ACTION: Final rule; notice of final action on reconsideration.
-----------------------------------------------------------------------
SUMMARY: In this action the EPA is taking final action on its
reconsideration of certain issues in the emission standards for the
control of hazardous air pollutants from new and existing industrial,
commercial, and institutional boilers and process heaters at major
sources of hazardous air pollutants, which were issued under section
112 of the Clean Air Act. As part of this action, the EPA is making
technical corrections to the final rule to clarify definitions,
references, applicability and compliance issues raised by petitioners
and other stakeholders affected by this rule. On March 21, 2011, the
EPA promulgated national emission standards for this source category.
On that same day, the EPA also published a notice announcing its intent
to reconsider certain provisions of the final rule. Following these
actions, the Administrator received several petitions for
reconsideration. After consideration of the petitions received, on
December 23, 2011, the EPA proposed revisions to certain provisions of
the March 21, 2011, final rule, and requested public comment on several
provisions of the final rule. The EPA is now taking final action on the
proposed reconsideration.
DATES: The May 18, 2011 (76 FR28661), delay of the effective date
revising subpart DDDDD at 76 FR 15451 (March 21, 2011) is lifted
January 31, 2013. The amendments in this rule to 40 CFR part 63,
subpart DDDDD are effective as of April 1, 2013.

SUPPLEMENTARY INFORMATION:
Executive Summary
Purpose of This Regulatory Action
The EPA is taking final action on its proposed reconsideration of
certain provisions of its March 21, 2011, final rule that established
standards for new and existing industrial, commercial, and
institutional boilers and process heaters at major sources of hazardous
air pollutants. Section 112(d) of the CAA requires the EPA to regulate
HAP from major stationary sources based on the performance of MACT.
Section 112(h) of the CAA allows the EPA to establish work practice
standards in lieu of numerical emission limits only in cases where the
agency determines that it is not feasible to prescribe or enforce an
emission standard, including circumstances in which the agency
determines that the application of measurement methodology is not
practicable due to technological and economic limitations. The EPA is
revising certain MACT standards established in March 2011 for boilers
and process heaters, including standards for CO--as a surrogate for
organic HAP; HCl--as a surrogate for acid gas HAP; Hg; TSM or
filterable PM--as a surrogate for non-Hg metallic HAP; and dioxin/
furan.
This final rule amends certain provisions of the final rule issued
by the EPA on March 21, 2011. The EPA delayed the effective date of the
2011 rule in a May 18, 2011, notice, but that delay notice was vacated
by the U.S. District Court for the District of Columbia on January 9,
2012, and the March 2011 final rule was, therefore, in effect until
publication of this action.
Summary of Major Reconsideration Provisions
In general, this final rule requires facilities classified as major
sources of HAP with affected boilers or process heaters to reduce
emissions of harmful toxic air emissions from these combustion sources.
This will improve air quality and protect public health in communities
where these facilities are located.
Recognizing the diversity of this source category and the multiple
sectors of the economy this final rule effects, the EPA is revising
certain subcategories for boilers and process heaters in this action
that were established in the March 2011 final rule, based on the design
of the combustion equipment. These revisions result in 19 subcategories
for the boilers and process heaters source category. Numerical emission
limits are established for most of the subcategories for five
pollutants, CO, HCl, Hg, and PM or TSM. The review of existing data and
consideration of new data have resulted in changes to some of the
emission limits contained in the March 2011 final rule. Overall, for
both new and existing affected units, about 30 percent of the emission
limits are more stringent, half are less stringent, and 20 percent
unchanged as compared to the March 2011 final rule. Also, based on its
review and analysis of new data submissions, the EPA is establishing an
alternative emission standard for CO, based on CEMS data for several
subcategories with CO CEMS data available. This alternative standard is
based on a 30-day rolling average for subcategories for which
sufficient CEMS data were available for more than a 30-day period, or a
10-day rolling average for subcategories for which CEMS data were
available for less than a 30-day period, and provides additional
compliance flexibility to sources. All of the subcategories are subject
to periodic tune-up work practices for dioxin/furan emissions.
The compliance dates for the rule are January 31, 2016, for
existing sources and, January 31, 2013, or upon startup, whichever is
later, for new sources. New sources are defined as sources that began
operation on or after June 4, 2010.
Costs and Benefits
The final rule affects 1,700 existing major source facilities with
an estimated 14,136 boilers and process heaters and the EPA projects an
additional 1,844 new boilers and process heaters to be subject to this
final rule over the next 3
[[Page 7139]]
years. This final rule affects multiple sectors of the economy
including small entities. Table 1 summarizes the costs and benefits
associated with this final rule. A more detailed discussion of the
costs and benefits of this final rule is provided in section VI of this
preamble.

----------------------------------------------------------------------------------------------------------------
\1\ All estimates are for the implementation year (2015), and are rounded to two significant figures.
\2\ The total monetized co-benefits reflect the human health benefits associated with reducing exposure to PM2.5
through reductions of PM2.5 precursors such as directly emitted particles, SO2, and NOX and reducing exposure
to ozone through reductions of VOC. It is important to note that the monetized benefits include many but not
all health effects associated with PM2.5 exposure. Monetized benefits are shown as a range from Pope et al.
(2002) to Laden et al. (2006). These models assume that all fine particles, regardless of their chemical
composition, are equally potent in causing premature mortality because the scientific evidence is not yet
sufficient to support the development of differential effects estimates by particle type. These estimates
include the energy disbenefits valued at $24 million (using the 3 percent discount rate), which do not change
the rounded totals. CO2-related disbenefits were calculated using the ``social cost of carbon,'' which is
discussed further in the RIA.
\3\ The methodology used to estimate social costs for one year in the multimarket model using surplus changes
results in the same social costs for both discount rates.

II. Background Information
A. Chronological History of Related Actions
On March 21, 2011, the EPA issued final standards for new and
existing industrial, commercial, and institutional boilers and process
heaters, pursuant to its authority under section 112 of the CAA. On the
same day as the final rule was issued, the EPA stated in a separate
notice that it planned to initiate a reconsideration of several
provisions of the final rule. This reconsideration notice identified
several provisions of the March 2011 final rule where additional public
comment was appropriate. This notice also identified several issues of
central relevance to the rulemaking where reconsideration was
appropriate under CAA section 307(d).
On May 18, 2011, the EPA issued a notice to postpone the effective
date of the March 21, 2011 final rule. Following promulgation of the
final rule, the EPA received petitions for reconsideration from the
following organizations
[[Page 7141]]
(``Petitioners''): AIE, USCHPA, Alyeska Pipeline, ACC, AHFA, AISI,
ACCCI, AMP, API, NPRA, AIF, Citizens Energy Group (CEG), CIBO, CMI,
District Energy St. Paul, FSI, GPSP, Hovensa L.L.C., Tesoro Hawaii
Corp., Industry Coalition (AF&PA et al.), JELD-WEN Inc., MSU, PSU,
Purdue University, Renovar Energy Corp., RPU, Sierra Club, Southeastern
Lumber Manufacturers Association, State of Washington Department of
Ecology, BCSE, UARG, US Sugar, WM and WEPCO. Copies of these petitions
are provided in the docket (see Docket ID No. EPA-HQ-OAR-2002-0058).
Petitioners, pursuant to CAA section 307(d)(7)(B), requested that the
EPA reconsider numerous provisions in the rule. On December 23, 2011,
the EPA granted the petitions for reconsideration on certain issues,
and proposed certain revisions to the final rule in response to the
reconsideration petitions and to address the issues that the EPA
previously identified as warranting reconsideration. That proposal
solicited comment on several specific aspects of the rule, including:
Revising the proposed subcategories.
Solicitation of new data or corrections to existing data
to revise emission standards calculations.
Establishing an alternative TSM limit.
Appropriateness of an alternative TSM limit for the liquid
subcategories.
Establishing work practice standards for dioxin/furan
emissions.
Revising the efficiency assumptions for the alternative
output-based emission standards.
Accommodating emissions averaging provisions in the
alternative output-based emission standards.
Establishing a mercury fuel specification through which
gas-fired boilers that use a fuel other than natural gas or refinery
gas may be considered Gas 1 units.
Establishing a work practice standard for limited use
units.
Providing an affirmative defense for malfunction events.
Revisions to the monitoring requirements for oxygen in the
March 2011 final rule.
Establishing a full-load stack test requirement for carbon
monoxide coupled with continuous oxygen (oxygen trim) monitoring.
Revising PM monitoring requirements from CEMS to CPMS and
exempting biomass units from PM CPMS requirements.
Revising mercury monitoring requirements to allow for an
alternative mercury CEMS.
Considering use of SO2 CEMS to demonstrate
compliance with HCl limits.
Minimum data availability provisions.
Averaging times for monitored parameters and pollutants.
Revised methods for computing minimum detection levels.
Providing an alternative CO emission limit based on CO
CEMS data.
Soliciting additional data to set MACT floor emission
limits for non-continental liquid units.
Selecting a 99 percent confidence interval for setting the
CO emission limit.
Tune-up frequencies, timing of initial tune-ups and
adjusted tune-up requirements for shutdown units.
Scope and duration of the energy assessment and deadline
for completing the assessment.
Revising work practices during startup and shutdown.
Revisions to certain exemptions, including units serving
as control devices, waste heat process heaters, units firing comparable
fuels and residential units.
Revisions to reduced testing frequency for emission limits
that are established at minimum detection levels.
Removing fuel analysis requirements for gas 1 fuels at co-
fired units.
Revisions to automating techniques for coal sampling.
Revisions to emissions averaging across subcategories when
units opt to switch to natural gas.
Consideration of a new subcategory for units installed and
used in place of flares.
In this action, the EPA is finalizing multiple changes to the March
2011 final rule after considering public comments on the items under
reconsideration.
III. Summary of This Final Rule
As stated above, the December 23, 2011 proposed rule addressed
specific issues and provisions the EPA identified for reconsideration.
This summary of the final rule reflects the changes to 40 CFR part 63,
subpart DDDDD (March 21, 2011 final rule) in regards to those
provisions identified for reconsideration and on other discrete matters
identified in response to comments or data received during the comment
period. Information on other provisions and issues not proposed for
reconsideration is contained in the notice and record for the 2011
final rule. [See 76 FR 15608]
This section summarizes the requirements of this action. Section IV
below provides a summary of the significant changes to the March 21,
2011 final rule.
A. What is an affected source?
This final rule revises the list of exemptions in Sec. 63.7491 to
include residential boilers that may be located at an industrial,
commercial or institutional major source. The exemption for boilers or
process heaters used specifically for research and development has been
revised to include boilers used for certain testing purposes.
B. What are the subcategories of boilers and process heaters?
In this final rule, we are finalizing separate subcategories for
heavy liquid-fired, light liquid-fired and liquid-fired units in non-
continental locations for PM and CO, pollutants that are dependent on
combustor design. In addition, a new subcategory for coal-fired
fluidized bed boilers with integrated fluidized bed heat exchangers has
been included in the final rule for CO which is dependent on boiler
design. Finally, we are finalizing the subcategory for PM at coal/
fossil solid units across all coal combustor designs.
C. What emission limits and work practice standards are being
finalized?
You must meet the emission limits presented in Table 3 of this
preamble for each subcategory of units listed in the table. This final
rule includes 19 subcategories, which are based on unit design. New and
existing units in three of the subcategories are subject to work
practices standards in lieu of emission limits for all pollutants.
Numeric emission limits are finalized for new and existing sources in
each of the other 16 subcategories.
The changes associated with the emission limits are due to new
data, corrections to old data, and inventory changes. In summary, for
existing subcategories, for the HCl emission limits, 10 are more
stringent, 3 are less stringent and 1 remained the same from the March
21, 2011 final rule; for the mercury emission limits, 3 are more
stringent and 11 are less stringent from the March 21, 2011 final rule;
for the PM emission limits, 2 are more stringent, 7 are less stringent
and 5 are unchanged from the March 21, 2011 final rule; and for the CO
emission limits, 4 are more stringent and 10 are less stringent from
the March 21, 2011 final rule. For new subcategories, for the HCl
emission limits, 13 are less stringent and 1 is unchanged from the
March 21, 2011 final rule; for the mercury emission limits, 11 are more
[[Page 7142]]
stringent, 2 are less stringent and 1 is unchanged from the March 21,
2011 final rule; for the PM emission limits, 9 are less stringent and 5
are unchanged from the March 21, 2011 final rule; and for the CO
emission limits, 3 are more stringent and 11 are less stringent from
the March 21, 2011 final rule.

We also are finalizing a work practice standard for dioxin/furan
emissions from all subcategories.
D. What are the requirements during periods of startup and shutdown?
We are finalizing revised work practice standards for periods of
startup and shutdown to better reflect the maximum achievable control
technology during those periods. In addition, we are finalizing
definitions of startup and shutdown. We are defining startup as the
period between the state of first-firing of fuel in the unit after a
shutdown to the period where the unit first supplies steam. We are
defining shutdown as the period that begins when no more steam is
supplied or at the point of no fuel being fired in the unit. For
periods of startup and shutdown, we are finalizing the following work
practice standard: You must operate all continuous monitoring systems
during startup and shutdown. For startup, you must use one or a
combination of the listed clean fuels. Once you start firing coal/solid
fossil fuel, biomass/bio-based solids, heavy liquid fuel, or gas 2
(other) gases, you must engage all of the applicable control devices
except limestone injection in FBC boilers, dry scrubber, fabric filter,
SNCR and SCR. You must start your limestone injection in FBC boilers,
dry scrubber, fabric filter, SNCR and SCR systems as expeditiously as
possible. During shutdown while firing coal/solid fossil fuel, biomass/
bio-based solids, heavy liquid fuel, or gas 2 (other) gases during
shutdown, you must operate all applicable control devices, except
limestone injection in FBC boilers, dry scrubber, fabric filter, SNCR
and SCR. You must comply with all applicable emissions and operating
limits at all times the unit is in operation except for periods that
meet the definitions of startup and shutdown in this subpart, during
which times you must comply with these work practices. You must keep
records during periods of startup or shutdown. You must keep records
concerning the date, duration, and fuel usage during startup and
shutdown.
E. What are the testing and initial compliance requirements?
We are requiring that the owner or operator of a new or existing
boiler or process heater conduct performance tests to demonstrate
compliance with all applicable emission limits. This final rule adds
the requirement to conduct initial and annual stack tests to determine
compliance with the TSM emission limits using EPA Method 29 for those
subcategories with alternate TSM limits.
[[Page 7143]]
F. What are the continuous compliance requirements?
This final rule removes the requirement for units combusting
biomass with heat input capacities of 250 MMBtu/hr or greater to
install, certify, maintain and operate a CEMS measuring PM emissions.
This final rule requires units combusting solid fossil fuel or heavy
liquid with heat input capacities of 250 MMBtu/hr or greater to
install, certify, maintain, and operate PM CPMS. Moreover, owners or
operators of units combusting solid fossil fuel or heavy liquid with
heat input capacities of 250 MMBtu/hr or greater are allowed to
install, certify, maintain and operate PM CEMS as an alternative to the
use of PM CPMS, consistent with regulations for similarly-sized
commercial and industrial solid waste incinerators units and EGUs
subject to the MATS. Just as units using PM CPMS will not be required
to conduct parameter monitoring for PM, units using PM CEMS will not be
required to conduct parameter monitoring for PM.
This final rule also includes an alternative method of
demonstrating continuous compliance with the HCl emission limit. This
method allows using SO2 emissions as an alternate operating
limit. This method of demonstrating continuous compliance will be
allowed only on a unit that utilizes a SO2 CEMS and an acid-
gas control technology including wet scrubber, dry scrubbers and duct
sorbent injection. Boilers or process heaters subject to an HCl
emission limit that demonstrate compliance with an SO2 CEMS
would be required to maintain the 30-day rolling average SO2
emission rate at or below the highest hourly average SO2
concentration measured during the most recent HCl performance test.
G. What are the compliance dates?
For existing sources, the EPA is establishing a compliance date of
January 31, 2016. New sources must comply by January 31, 2013, or upon
startup, whichever is later. New sources are defined as sources which
commenced construction or reconstruction on or after June 4, 2010
pursuant to section 112(a)(4).
Commenters have argued that the 3-year compliance deadline the EPA
is establishing for existing sources to meet the standards does not
provide them with sufficient time to meet the standards in view of the
large number of sources that will be competing for the needed resources
and materials from engineering consultants, permitting authorities,
equipment vendors, construction contractors, financial institutions,
and other critical suppliers.
As an initial matter, we note that many sources subject to the
emission standards in the final rule should be able to meet the
standards within three years, even those that need to install pollution
control technologies to do so. In addition, many sources subject to the
rule are gas fired units or small boilers (less than 10 MMBtu/hr) and
will not need to install controls in order to demonstrate compliance,
as these sources are subject to work practice standards. For these
sources, the 3-year compliance deadline is highly unlikely to be
problematic either in general, or with respect to the claims commenters
have made about the possibility that the demand for resources related
to control technology will exceed the supply.
At the same time, the CAA allows title V permitting authorities to
grant sources, on a case-by-case basis, extensions to the compliance
time of up to one year if such time is needed for the installation of
controls. See CAA section 112(i)(4)(i)(A). Permitting authorities are
already familiar with, and in many cases have experience with, applying
the 1-year extension authority under section 112(i)(4)(A) since the
provision applies to all NESHAP. We believe that should the range of
circumstances that commenters have cited as impeding sources' ability
to install controls within three years materialize, then it is
reasonable for permitting authorities to take those circumstances into
consideration when evaluating a source's request for a 1-year
extension, and where such applications prove to be well-founded, it is
also reasonable for permitting authorities to make the 1-year extension
available to applicants.
In making a determination as to whether an extension is
appropriate, we believe it is also reasonable for permitting
authorities to consider the large number of pollution control retrofit
projects being undertaken for purposes of complying either with the
standards in this rule or with those of other rules such as MATS for
the power sector that may be competing for similar resources.
Further, commenters have pointed out that in some cases operators
of existing sources that are subject to these standards and that
generate energy may opt to meet the standards by terminating operations
at these sources and building new sources to replace the energy
generation at the shut-down sources. While the ultimate discretion to
provide a 1-year extension lies with the permitting authority, the EPA
believes that it is reasonable for permitting authorities to allow the
fourth year extension for the installation of replacement sources of
energy generation at the site of a facility applying for an extension
for that purpose. Specifically, the EPA believes where an applicant
demonstrates that it is building replacement sources of energy
generation for purposes of meeting the requirements of these standards
such a replacement project could be deemed to constitute the
``installation of controls'' under section 112(i)(3)(B).
In a case where pollution controls are being installed or onsite
replacement energy generation is being constructed to allow for
retirement of older, under-controlled energy generation units, a
determination that an extra year is necessary for compliance should be
relatively straightforward. In order to install controls, companies are
likely to undertake a number of steps relatively soon after the
effective date of the rule, including obtaining necessary building and
environmental permits and hiring contractors to perform the
construction of the emission controls or replacement energy generation
units. This should provide sufficient information for a permitting
authority to determine that emission controls are being installed or
that replacement energy generation is being constructed. As a result, a
permitting authority will be in a position to make a determination as
to whether a source's compliance schedule will exceed 3 years and to
quickly make a determination as to when an extension is appropriate.
In sum, the EPA believes that although most, if not all, units will
be able to fully comply with the standards within 3 years, the fourth
year that permitting authorities are allowed to grant for installation
of controls is an important flexibility that will address situations
where an extra year is necessary. Of course in situations where EPA is
the permitting authority, we would also consider the above
circumstances when acting on a permit application.
IV. Summary of Significant Changes Since Proposal
The EPA has made numerous changes in this final rule from the
proposal after consideration of the public comments received. Most are
changes to clarify applicability and implementation issues raised by
the commenters. The public comments received on the proposed changes
and the responses to them can be viewed in the memorandum ``Response to
Comments for Industrial, Commercial, and Institutional Boilers
[[Page 7144]]
and Process Heaters National Emission Standards for Hazardous Air
Pollutants'' located in the docket.
A. Applicability
Since proposal, the EPA has made certain changes to the
applicability of this final rule. We have clarified that the exemption
for boilers and process heaters used for research and development
includes boilers used for testing the propulsion systems on military
vessels. This is consistent with the intent of the exemption in that
these test boilers do not provide steam for heating, to a process, or
other non-propulsion related uses but are used exclusively to test the
propulsion systems of nuclear-powered aircraft carriers that are
undergoing repair, overhaul, or installation.
B. Subcategories
As described in the preamble to the proposed reconsideration rule,
within the basic unit types of boilers and process heaters there are
different designs and combustion systems that, while having a minor
effect on fuel-dependent HAP emissions, have a much larger effect on
pollutants whose emissions depend on the combustion conditions in a
boiler or process heater. In the case of boilers and process heaters,
the combustion-related pollutants are the organic HAP. In the proposed
rule, we identified the following 17 subcategories for organic HAP: (1)
Pulverized coal units; (2) stokers designed to burn coal; (3) fluidized
bed units designed to burn coal; (4) stokers designed to burn wet
biomass; (5) stokers designed to burn kiln-dried biomass; (6) fluidized
bed units designed to burn biomass; (7) suspension burners designed to
burn biomass; (8) dutch ovens/pile burners designed to burn biomass;
(9) fuel cells designed to burn biomass; (10) hybrid suspension grate
units designed to burn biomass; (11) units designed to burn heavy
liquid fuel; (12) units designed to burn light liquid fuel; (13) non-
continental liquid units; (14) units designed to burn natural gas/
refinery gas; (15) units designed to burn other gases; (16) metal
process furnaces; and (17) limited-use units.
In this final rule, we are also adding a separate subcategory for
fluidized bed units with a fluidized bed heat exchanger designed to
burn coal and adjusted the definition of the limited use subcategory.
Fluidized bed boilers are designed to combust fuel with relatively
low heating value and high ash compared to other combustor designs. Two
fuel properties of coal are heating values and ash content. As the
heating value of the coal decreases, ash content increases. Fluidized
bed boilers are designed to have large tube surface areas to transfer
heat from the fuel through the process of conduction and convection,
but in some cases the amount of tube surface area in the furnace for
heat transfer is insufficient. In order to overcome insufficient heat
exchange, certain fluidized bed boilers adopt a fluidized bed heat
exchanger design to achieve heat transfer. The fluidized bed heat
exchanger is located at the exit of the cyclone section of the unit.
This design allows the boiler to combust coal with a lower heating
value than a coal-fired fluidized bed boiler without a fluidized bed
heat exchanger. Therefore, because this boiler design does have
different combustion-related HAP emission characteristics, a new
subcategory of coal fluidized bed with integrated heat exchanger was
added to the final rule.
The EPA is also revising the definition of the limited use
subcategory. Many affected units operate on standby mode or low loads
for periods longer than the proposed definition for limited use units,
which limited operation to 876 hours per year. By converting to a
capacity-factor approach, we are allowing more flexibility on unit
operations without increasing emissions or harm to human health and the
environment. For example, units operating at 10 percent load for 8,760
hours per year would emit the same amount of emissions as units
operating at full load for 876 hours per year. Further, it is
technically infeasible to schedule stack testing for these limited use
units since these units serve as back up energy sources and their
operating schedules can be intermittent and unpredictable. The limited
use subcategory was adjusted to be based on units with a federally
enforceable operating limit of less than or equal to 10 percent of an
average annual capacity factor.
C. Performance Test Requirements
Table 5 of this final rule has been revised to add performance test
procedures for conducting performance stack tests for demonstrating
compliance with the alternate TSM emission limits. In the
reconsideration proposal, we proposed emissions limits for TSM (i.e.,
arsenic, beryllium, cadmium, chromium, lead, manganese, nickel and
selenium) as an alternative to the proposed PM emission limits for many
of the subcategories. In the preamble to the proposed rule, we added
procedures in Table 6 of the rule for conducting fuel analysis for
total selected metals but we inadvertently failed to add performance
test requirements for stack sampling of TSM emissions in Table 5 of the
rule.
D. Emission Limits
One significant change since proposal is related to the PM emission
limits for the coal subcategories. Several petitioners disagreed with
EPA's position to set different PM limits for subcategories of boilers
and process heaters based on the fuel used, and instead offered
information to support the position that PM should be considered a
combustion-based pollutant. The differences in PM particle size,
fouling characteristics and feasibility of certain control technologies
on certain unit designs suggested that PM is more appropriately
classified as a combustion-based pollutant, but only for the coal
subcategories. After assessing the points raised by the petitioners,
the EPA agreed that PM emissions are influenced by unit design, and
fuel type, and proposed to create combustion-based pollutant
subcategories for coal and solid fuels and create fuel-based
subcategories for liquid and biomass fuel units. The EPA is finalizing
a single PM limit for all coal/solid fossil fuel subcategories, and is
also finalizing emissions limits based on PM as a combustion-based
pollutant for the biomass and liquid fuel subcategories.
Another change from proposal is that the alternative TSM emission
limits are now applicable to the three liquid fuel subcategories.
Several commenters provided data and comments supporting these
alternative emission standards for non-mercury metallic HAP. After
assessing the revised data and the points made by the commenters, the
EPA agrees that the limited data available for liquid fuel units are
not unique to this subcategory. Based on the EPA agreeing with the
commenters, the EPA re-calculated the TSM emission limits for the
liquid fuel subcategories and included them in the final rule.
The CO emission limit for several subcategories, both new and
existing, have been revised to reflect a CO level that is consistent
with MACT for organic HAP reduction. Several commenters recommended
that the EPA evaluate a minimum CO standard (i.e., 100 ppm corrected to
7 percent oxygen) to serve as a lower bound surrogate for organic HAP.
Commenters also provided data and information to support such a
standard, and noted that the EPA has taken a similar approach in other
emission standards under section 112.
The EPA evaluated whether there is a minimum CO level for boilers
and
[[Page 7145]]
process heaters below which there is no further benefit in organic HAP
reduction/destruction. Specifically, we evaluated the relationship
between CO and formaldehyde using the available data obtained during
the rulemaking. Formaldehyde was selected as the basis of the organic
HAP comparison because it is the most prevalent organic HAP in the
emission database and a large number of paired tests existed for
boilers and process heaters for CO and formaldehyde. The paired data
show decreasing formaldehyde emissions with decreasing CO emissions
down to CO levels around 300 ppm, supporting the selection of CO as a
surrogate for organic HAP emissions. A slight increase in formaldehyde
emissions is observed at CO levels below around 200 ppm, suggesting a
breakdown in the CO-formaldehyde relationship at low CO levels. At
levels lower than 150 ppm, the mean levels of formaldehyde appear to
increase, as does the overall maximum value of and variability in
formaldehyde emissions. However, we are aware of no reason why CO
concentrations would continue to decrease and formaldehyde
concentrations would increase as combustion conditions improve. It is
possible that imprecise formaldehyde measurements at low concentrations
(i.e., 1-2 ppm) may account for this slight increase in formaldehyde
emissions observed at CO levels below 100 ppm corrected to 7 percent
oxygen. Based on this, we do not believe that such measurements are
sufficiently reliable to use as a basis for establishing an emissions
limit.
Therefore, based on the above analysis, we are promulgating a
minimum MACT floor level for CO of 130 ppm corrected to 3 percent
oxygen (which is equivalent to 100 ppm corrected to 7 percent oxygen).
We note this is the same approach used to establish the CO emission
limit of 100 ppm corrected to 7 percent oxygen for the Burning of
Hazardous Waste in Boilers and Industrial Furnaces rule. Additional
discussion of the rationale for this approach can be found in the
memorandum ``Revised MACT Floor Analysis (August 2012) for Industrial,
Commercial, Institutional Boilers and Process Heaters National Emission
Standards for Hazardous Air Pollutants--Major Source.''
Subcategories where the initial MACT floor 99 percent UPL
calculations for CO were less than 100 ppm corrected to 7 percent
oxygen (or equivalently 130 ppm corrected to 3 percent oxygen) are as
follows:
New and Existing Subcategories: Coal-FB, Coal-PC, Heavy
Liquid, Light Liquid, Non-Continental Liquid, Process Gas
New Subcategories: Coal-Stoker
We believe a CO level of 130 ppm corrected to 3 percent oxygen is an
appropriate minimum MACT floor level. Although some measurements show
CO levels below 130 ppm corrected to 3 percent oxygen, it is not
appropriate to establish a lower floor level because CO is a
conservative surrogate for organic HAP. In other words, organic HAP
emissions are extremely low when sources operate under the good
combustion conditions required to achieve CO levels in the range of
zero to 100 ppm. As such, lowering the CO floor below 100 ppm will not
provide reductions in organic HAP emissions. There are myriad factors
that affect combustion efficiency and, as a function of combustion
efficiency, CO emissions. As combustion conditions improve and
hydrocarbon levels decrease, the larger and easier to combust compounds
are oxidized to form smaller compounds that are, in turn, oxidized to
form CO and water. As combustion continues, CO is then oxidized to form
carbon dioxide and water. Because CO is a difficult to destroy
refractory compound (i.e., oxidation of CO to carbon dioxide is the
slowest and last step in the oxidation of hydrocarbons), it is a
conservative surrogate for destruction of hydrocarbons, including
organic HAP.
The conservative nature of CO as an indicator of good combustion
practices is supported by our data. At CO levels less than 100 ppm
corrected to 7 percent oxygen, our data indicate that there is no
apparent relationship between CO and organic HAP (i.e., formaldehyde).
For example, a source with a CO level of 20 ppm may have the same
measured formaldehyde as a source achieving a CO emission level of 100
ppm corrected to 7 percent oxygen. Sources are required to establish
operating requirements based on operating levels that were demonstrated
during the test. Sources must comply with these operating requirements
on a continuous basis. Compliance with these requirements adequately
assures sources will be controlling organic HAP emissions to MACT
levels.
As detailed in the docketed memorandum ``Beyond the Floor
Technology Analysis for Major Source Boilers and Process Heaters
(Revised August 2012),'' we reviewed the emission limits that are
becoming less stringent since the March 2011 final rule in order to
assess whether a beyond the floor option was technically achievable and
cost effective. As a result of this review, the PM emission limits for
several new biomass subcategories have been changed to reflect a beyond
the floor limit of 0.03 lb/MMBtu, based on the limit for new biomass
boilers in 40 CFR part 60 subparts Db and Dc. Due to the low mercury
emission limits for new solid fuel boilers, these new biomass units are
expected to install a fabric filter level of control in order to meet
the new source mercury limits for the solid fuel subcategory. This
mercury control has the co-benefit of reducing PM emissions down to
levels of 0.03 lb/MMBtu so there is no incremental cost to achieve
these additional reductions in PM for the biomass units that have a
design heat input capacity between 10 and 30 MMBtu/hr. For units with a
design heat input capacity of 30 MMBtu/hr or greater, these units are
already subject to a PM limit of 0.03 lb/MMBtu and adjusting these new
source limits to this level of control makes the limits consistent
between both rules, without adding additional costs. We did not
identify any beyond the floor options for existing source PM limits or
new and existing limits for other pollutants as technically feasible or
cost effective.
The other changes associated with the other emission limits are due
to new data, corrections to old data, and inventory changes. In
summary, compared to the December 23, 2011 proposed limits for existing
units, the final HCl emission limits remained the same; for the final
mercury emission limits, 3 are more stringent, 10 are less stringent
and 1 is unchanged; for the final PM emission limits, 3 are more
stringent, 5 are less stringent and 6 are unchanged; and for the final
CO emission limits, 3 are more stringent and 11 are less stringent. For
new units, compared to the proposed emission limits, 3 of the final HCl
emission limits are more stringent and 11 remained the same; for the
final mercury emission limits, 10 are more stringent and 4 are
unchanged; for the final PM emission limits, 5 are more stringent, 2
are less stringent and 7 are unchanged; and for the final CO emission
limits, 2 are more stringent, 11 are less stringent and 1 is unchanged.
E. Work Practice Requirement
In this final rule several changes have been made to the work
practice requirement to conduct a tune-up. First, the requirement to
inspect the burner has been revised to allow units that sell
electricity to schedule the burner inspection, as well as the air-to-
fuel system inspection, at the time of the first outage but not to
exceed 36 months from the previous inspection. This
[[Page 7146]]
change is being made to this final rule because commenters stated that
large boilers that serve electricity for sale may not require annual
outages and would, therefore, need to be taken off-line for the sole
purpose of an annual tune-up. This frequency is consistent with the
requirements of the NESHAP for electric utility boilers (40 CFR part
63, subpart UUUUU).
Also, for units where entry into a piece of process equipment or
into a storage vessel is required to complete the tune-up inspections,
inspections are required only during planned entries into the storage
vessel or into process equipment. Commenters indicated that some
process heaters are installed inside tanks and entry into the tank to
access the heater may not occur within a 5 year period.
The requirement to optimize total emissions of CO has been revised
to require that this optimization not only be consistent with the
manufacturer's specifications but also with any NOX emission
requirement to which the unit is subject. Some commenters indicated
that many boilers need different tune-up criteria due to their
requirement to also comply with low NOX emission limits. We
are also aware that several states have boiler tune-up requirements to
minimize NOX emissions first and then optimize CO emissions.
We have added boilers or process heaters that have a continuous
oxygen trim system to the types of boilers or process heaters that must
conduct a tune-up every 5 years. These units do not need to be tuned as
frequently because the trim system is designed to continuously measure
and maintain an optimum air to fuel ratio which is the purpose of a
tune-up.
F. Averaging Times Definitions
We revised the definitions of ``30-day rolling average'' and
``daily block average'' to exclude periods of startup and shutdown or
downtime from the arithmetic mean. Commenters requested that the EPA
specify how a 30-day rolling average is calculated and whether it
includes the previous 720 hours of valid operating data and that the
valid data exclude hours during startup and shutdown as well as unit
down time. We agree with the commenters that the definitions need
clarification and that these periods should not be included in
calculating the 30-day rolling average. Therefore, we have revised the
definitions accordingly.
We have also included in the final rule a definition of ``10-day
rolling average'' that is consistent with the revised definition of
``30-day rolling average.''
G. Energy Assessment
In this final rule, we have revised the definition of energy
assessment per the requirements of Table 3 of this final rule by
providing duration for performing the energy assessment for large fuel
use facilities. In numbered paragraph (3) in the definition of ``Energy
assessment'' in Sec. 63.7575, which is for facilities with units
having a combined heat input capacity greater than 1 TBtu/yr, we added
time duration/size ratio and included a cap to the maximum number of
on-site technical hours that should be used in the energy assessment.
This addition of a duration for large fuel use facilities is being made
to be consistent with durations specified for small [paragraph (1) in
the definition of ``Energy assessment''] and medium [paragraph (2) in
the definition of ``Energy assessment''] fuel use facilities. The
energy assessment for facilities with affected boilers and process
heaters having a combined heat input capacity greater than 1.0 TBtu/yr
will be up to 24 on-site technical labor hours for the first TBtu/yr
plus 8 technical labor hours for every additional 1.0 TBtu/yr not to
exceed 160 technical hours, but may be longer at the discretion of the
owner or operator.
The revised definition of energy assessment also clarifies our
intentions that the scope of assessment is based on energy use by
discrete segments of a facility and not by a total aggregation of all
individual energy using elements of a facility. The applicable discrete
segments of a facility could vary significantly depending on the site
and its complexity. We have added the following paragraph (4), to the
energy assessment definition to help resolve current problems in
identifying the scope of the various energy use systems in a large
industrial complex and allow for more streamlined assessments:
``(4) The on-site energy use systems serving as the basis for the
percent of affected boiler(s) and process heater(s) energy output in
(1), (2) and (3) above may be segmented by production area or energy
use area as most logical and applicable to the specific facility being
assessed (e.g., product X manufacturing area; product Y drying area;
Building Z).''
We have also revised paragraph 4 of Table 3 of the final rule to
allow a source that is operating under an energy management program
established through energy management systems compatible with ISO
50001, which includes the affected units, to satisfy the energy
assessment requirement. We consider these energy management programs to
be equivalent to the one-time energy assessment because facilities
having these programs operate under a set of practices and procedures
designed to manage energy use on an ongoing basis. These programs
contain energy performance measurements and tracking plans with
periodic reviews.
The definition of ``Energy use system'' has also been revised in
this final rule to clarify that energy use systems are only those
systems using energy clearly produced by affected boilers and process
heaters.
H. Startup and Shutdown Definitions
A number of commenters indicated that the proposed load
specifications (i.e., 25 percent load) within the definitions of
``startup'' and ``shutdown'' were inconsistent with either safe or
normal (proper) operation of the various types of boilers and process
heaters encountered within the source category. As the basis for
defining periods of startup and shutdown, a number of commenters
suggested alternative load specifications based on the specific
considerations of their boilers; other commenters suggested the
achievement of various steady-state conditions.
We have reviewed these comments and believe adjustments are
appropriate in the definition of ``startup'' and ``shutdown.'' These
adjustments are tailored for industrial boilers and are consistent with
the definitions of ``startup'' and ``shutdown'' contained in the 40 CFR
part 63, subpart A General Provisions. We believe these revised
definitions address the comments and are rational based on the fact
that industrial boilers function to provide steam or, in the case of
cogeneration units, electricity; therefore, industrial boilers should
be considered to be operating normally at all times steam of the proper
pressure, temperature, and flow rate is being supplied to a common
header system or energy user(s) for use as either process steam or for
the cogeneration of electricity. The definitions of ``startup'' and
``shutdown'' have been revised in the final rule as follows:
``Startup means either the first-ever firing of fuel in a boiler or
process heater for the purpose of supplying steam or heat for heating
and/or producing electricity, or for any other purpose, or the firing
of fuel in a boiler or process heater after a shutdown event for any
purpose. Startup ends when any of the steam or heat from the boiler or
process heater is supplied for heating and/or producing electricity, or
for any other purpose.''
[[Page 7147]]
``Shutdown means the cessation of operation of a boiler or process
heater for any purpose. Shutdown begins either when none of the steam
and heat from the boiler or process heater is supplied for heating and/
or producing electricity, or for any other purpose, or at the point of
no fuel being fired in the boiler or process heater, whichever is
earlier. Shutdown ends when there is both no steam or heat being
supplied and no fuel being fired in the boiler or process heater.''
The EPA is requiring sources to vent emissions to the main stack(s)
and operate all control devices necessary to meet the normal operating
standards under this final rule (with the exception of limestone
injection in FBC boilers, dry scrubber, fabric filter, SNCR and SCR)
when firing coal/solid fossil fuel, biomass/bio-based solids, heavy
liquid fuel or gas 2 (other) gases in the boiler or process heater
during startup or shutdown. It is the responsibility of the operators
of affected boilers and process heaters to start their limestone
injection in FBC boilers, dry scrubber, fabric filter, SNCR and SCR
systems appropriately to comply with relevant standards applicable
during normal operation. Startup ends and normal operating standards
apply when heat or steam is supplied for any purpose.
The EPA carefully considered fuels and potential operational
constraints of APCD when designing its work practices for periods of
startup and shutdown. The EPA notes that there is no technical barrier
to burning clean fuels (e.g., natural gas, distillate oil) for longer
portions of startup or shutdown periods at a boiler and the HAP
emission reduction benefits warrant additional utilization of such
fuels until the temperature and stack emissions pressure is sufficient
to engage the APCD. The EPA is aware that SNCR and SCR systems with
ammonia injection need to be operated within a prescribed and
relatively narrow temperature window to provide NOX
reductions. Further, the EPA is aware that dry scrubbers also need to
be operated close to flue gas saturation temperature, and that fabric
filters need to be operated at temperatures above the acid dew point.
Because these devices have specific temperature requirements for proper
operation, the EPA notes in its work practices that it is the
responsibility of the operators of affected boilers and process heaters
to start their SNCR, SCR, fabric filter and dry scrubber systems
appropriately to comply with relevant standards applicable during
normal operation.
I. Fuel Sampling Frequency
The sampling frequency for gaseous fuel-fired units that elected to
demonstrate that the unit meets the specification for mercury for the
unit designed to burn gas 1 subcategory has been revised in this final
rule. If the initial mercury constituents in the gaseous fuels are
measured to be equal to or less than half of the mercury specification,
no further sampling is required. If the initial mercury constituents
are greater than half but equal to or less than 75 percent of the
mercury specification, only semi-annual sampling need to be conducted.
If the initial mercury constituents are greater than 75 percent of the
mercury specification, monthly sampling is required.
J. Affirmative Defense
In the proposal, we used terms such as ``exceedance'' or ``excess
emissions'' in Sec. 63.7501, which created unnecessary confusion as to
when the affirmative defense could be used. In the final amended rule,
we have eliminated those terms and used the word ``violation'' to make
clear that the affirmative defense to civil penalties is available only
where an event that causes a violation of the emissions standard meets
the definition of malfunction under Sec. 63.2.
We have also eliminated the 2-day notification requirement that was
included in 40 CFR 63.7501(b) at proposal because we expect to receive
sufficient notification of malfunction events that result in violations
in other required compliance reports, such as the malfunction report
required under 40 CFR 63.7550(c). In addition, we have revised the 45-
day affirmative defense reporting requirement that was included in 40
CFR 63.7501(b) at proposal to require sources to include the report in
the first compliance, deviation or excess emission report due after the
initial occurrence of the violation, unless the compliance, deviation
or excess emission report is due less than 45 days after the violation.
In that case, the affirmative defense report may be included in the
second compliance, deviation or excess emission report due after the
initial occurrence of the violation. Because the affirmative defense
report is now included in a subsequent compliance, deviation or excess
emission report, there is no longer a need for the proposed 30-day
extension for submitting a stand-alone affirmative defense report.
Consequently, we are not including this provision in the final amended
rule. We have also re-evaluated the language concerning the use of off-
shift and overtime labor to the extent practicable and believe that the
language is not necessary. Thus, we have deleted that phrase from
section 63.7501(a)(2).
V. Other Actions We Are Taking
Section 307(d)(7)(B) of the CAA states that ``[o]nly an objection
to a rule or procedure which was raised with reasonable specificity
during the period for public comment (including any public hearing) may
be raised during judicial review. If the person raising an objection
can demonstrate to the Administrator that it was impracticable to raise
such objection within such time or if the grounds for such objection
arose after the period for public comment (but within the time
specified for judicial review) and if such objection is of central
relevance to the outcome of the rule, the Administrator shall convene a
proceeding for reconsideration of the rule and provide the same
procedural rights as would have been afforded had the information been
available at the time the rule was proposed. If the Administrator
refuses to convene such a proceeding, such person may seek review of
such refusal in the United States court of appeals for the appropriate
circuit (as provided in subsection (b)).''
As to the first procedural criterion for reconsideration, a
petitioner must show why the issue could not have been presented during
the comment period, either because it was impracticable to raise the
issue during that time or because the grounds for the issue arose after
the period for public comment (but within 60 days of publication of the
final action). The EPA is denying the petitions for reconsideration on
a number of issues because this criterion has not been met. In many
cases, the petitions reiterate comments made on the proposed June 2011
rule during the public comment period for that rule. On those issues,
the EPA responded to those comments in the final rule and made
appropriate revisions to the proposed rule after consideration of
public comments received. It is well-established that an agency may
refine its proposed approach without providing an additional
opportunity for public comment. See Community Nutrition Institute v.
Block, 749 F.2d at 58 and International Fabricare Institute v. EPA, 972
F.2d 384, 399 (D.C. Cir. 1992) (notice and comment is not intended to
result in ``interminable back-and-forth[,]'' nor is agency required to
provide additional opportunity to comment on its response to comments)
and Small Refiner Lead Phase-Down Task Force v. EPA, 705 F.2d 506, 547
(D.C. Cir. 1983) (``notice requirement
[[Page 7148]]
should not force an agency endlessly to repropose a rule because of
minor changes'')
In the EPA's view, an objection is of central relevance to the
outcome of the rule only if it provides substantial support for the
argument that the promulgated regulation should be revised. See Union
Oil v. EPA, 821 F.2d 768, 683 (D.C. Cir. 1987) (court declined to
remand rule because petitioners failed to show substantial likelihood
that final rule would have been changed based on information in
petition). See also the EPA's Denial of the Petitions to Reconsider the
Endangerment and Cause or Contribute Findings for Greenhouse Gases
under Section 202 of the Clean Air Act, 75 FR at 49556, 49561 (August
13, 2010). See also, 75 FR at 49556, 49560-49563 (August 13, 2010) and
76 FR at 4780, 4786-4788 (January 26, 2011) for additional discussion
of the standard for reconsideration under CAA section 307(d)(7)(B).
We are denying reconsideration on the following 57 issues contained
in the petitions for reconsideration because they failed to meet the
standard described above for reconsideration under CAA section
307(d)(7)(B). Specifically, on these issues, the petitioner has failed
to show the following: that it was impracticable to raise their
objections during the comment period or that the grounds for their
objections arose after the close of the comment period; and/or that
their concern is of central relevance to the outcome of the rule.
Therefore, the EPA is denying the petitions for reconsideration on the
issues for the reasons described below.
Issue: Delist gas units.
The petitioners (API, NPRA) requested that the EPA remove gas-fired
units from the section 112(c) list of source categories for which the
EPA is required to establish emissions standards under section 112(d).
The EPA is denying the petition for reconsideration for the following
reasons. First, the issue is outside the scope of this rulemaking,
which establishes emissions standards for new and existing units within
the major source boilers and process heaters source category. The EPA
did not solicit comment in the proposed rule regarding the scope of the
subcategory. Further, petitioners provide no information to support
delisting gas units under section 112(c)(9), which requires the EPA to
make certain findings before delisting any sources. In addition, the
petition does not address the D.C. Circuit's decision in NRDC v. EPA,
489 F.3d 1364 (2007), regarding the EPA's ability to delist
subcategories of a source category pursuant to section 112(c)(9). For
these reasons, the petitions do not provide support for the argument
that the regulation should be changed. For this reason, the petition
does not demonstrate that the issue is of central relevance to the
outcome of the final rule and the EPA is denying the request for
reconsideration.
Issue: Exempt natural gas hot water heaters with tanks greater than
120 gallons.
The petitioner (AIF) requested that the EPA exempt natural gas hot
water heaters with tanks greater than 120 gallons. While the EPA
disagrees with the petitioner regarding whether such units should be
subject to the emissions standards in this rule, the petitioner has not
demonstrated that it lacked the opportunity to comment on whether such
units should be required to meet emissions standards. The EPA proposed
work practice standards for such units in its June 2010 proposal, and
the petitioner had the opportunity to comment on whether such standards
should be applied to such units at all. Therefore, the EPA is denying
the request for reconsideration.
Issue: Exempt natural gas and distillate oil-fired circulating hot
water systems with a design capacity of 10 MMBtu/hr or less.
The petitioner (CIBO) requested that the EPA exempt natural gas and
distillate oil-fired circulation hot water systems that are not greater
than 10 MMBtu/hr. While the EPA disagrees with the petitioner regarding
whether such units should be subject to the emissions standards in this
rule, the petitioner has not demonstrated that it lacked the
opportunity to comment on whether such units should be required to meet
emissions standards. The EPA proposed emissions standards for such
units, and the petitioner had the opportunity to comment on whether
such standards should be applied to such units at all. In addition, the
petition does not provide any information to demonstrate that these
units should be delisted pursuant to section 112(c)(9). Therefore, the
EPA is denying the request for reconsideration.
Issue: Confirm in definitions that open flame heaters (e.g.,
asphalt tank heaters) are not process heaters.
The petitioners (API, NPRA) requested that the EPA clarify in the
definition of ``process heater'' that open flame heaters do not meet
the definition. While the EPA disagrees with the petitioners whether
clarification is needed in regards to open flame heaters, the
petitioners have not demonstrated that it lacked the opportunity to
comment on the proposed definition. The definition that the EPA
proposed clearly states that process heaters are enclosed devices in
which the combustion gases do not come into contact with process
materials, and as such, does not include open flame heaters. Therefore,
the EPA is denying reconsideration.
Issue: For blast furnace fuel-fired boiler exemption, compute the
90 percent BFG by volume threshold to exclude periods of BFG
curtailment.
The petitioners (AISI, ACCCI) requested that the EPA revise the
exemption for BFG fuel-fired boilers to exclude periods of BFG
curtailment. While the EPA disagrees with the petitioners regarding
revising the exemption, the petitioners have not demonstrated that it
lacked the opportunity to comment on the proposed exemption for BFG
fuel-fired boilers. The EPA proposed the exemption for these boilers,
and petitioners therefore had the opportunity to comment on whether the
exemption should apply to periods of BFG curtailment. Therefore, the
EPA is denying the request for reconsideration.
Issue: Exempt boilers whose flue gases are used in direct-fired
process heaters subject to other NESHAP.
The petitioner (CMI) requested that the EPA exempt from the rule
boilers whose flue gases are used in direct-fired process heaters that
are subject to other NESHAP. The final rule does not apply to such
units if they are subject to another NESHAP. The EPA does not see a
need for further clarification. Since the final rule does in fact
exempt these units, the EPA is denying the request for reconsideration.
Issue: Work practice standards do not meet EPA obligations under
112(c)(6).
The petitioner (Sierra Club) requested that the EPA establish
numeric emissions limits for Gas 1 units rather than work practice
standards. Specifically, the petitioner alleges that the work practice
standards do not meet the EPA's obligations under section 112(c)(6) of
the CAA, and that it was not the case that data were below the
detection level for all HAP emitted from these units. The EPA is
denying the request for reconsideration on this issue. While the EPA
disagrees with the petitioner's arguments regarding the legal authority
to establish work practice standards for Gas 1 units and the basis for
such standards, the petitioner has not demonstrated that it lacked the
opportunity to comment on this issue. The EPA proposed work practice
standards for Gas 1 units and explained in the proposal its rationale
for such standards, including the fact that a significant portion of
the
[[Page 7149]]
emissions data were below the detection level. 75 FR at 32024-25.
Therefore, the petitioner had the opportunity to comment on this issue,
and did in fact submit comments regarding the EPA's legal authority to
establish work practice standards for Gas 1 units. Therefore, the EPA
is denying reconsideration on this issue.
Issue: Work practices for small units are not justified by 112(h)
since small units were not given their own subcategory.
The petitioner (Sierra Club) requested that the EPA require small
units, those having a heat input capacity of less than 10 MMBtu/hr, to
meet numeric emissions limits rather than work practice standards. The
EPA is denying the request for reconsideration on this issue because
the petitioner has not demonstrated that it lacked the opportunity to
comment on this issue. The EPA proposed work practice standards for
these units and explained in the proposal its rationale for such
standards. 75 FR at 32024-25. The EPA did in fact receive comments
regarding the proposed standards, to which it responded in the final
rule. 76 FR at 15640. Moreover, the EPA notes that nothing in section
112(h) limits the EPA's discretion to establish work practice standards
to the establishment of such standards for an entire category or
subcategory. Therefore, the EPA is denying the request for
reconsideration.
Issue: PM is not an adequate surrogate for non-mercury metallic
HAP.
The petitioner (Sierra Club) requested that the EPA remove the PM
standard as a surrogate for non-mercury metallic HAP and instead adopt
a numeric limit for non-mercury metallic HAP because PM is not an
appropriate surrogate. The EPA is denying the request for
reconsideration on this issue. While the EPA disagrees with the
petitioner's argument regarding the suitability of PM as a surrogate
for non-mercury metallic HAP, the petitioner has not demonstrated that
it lacked the opportunity to comment on this issue. The EPA proposed PM
standards as a surrogate for non-mercury metallic HAP and explained in
the proposal the agency's basis for concluding that PM was an
appropriate surrogate. 75 FR at 32018. Therefore, the EPA is denying
the request for reconsideration.
Issue: Establish direct limits on organics or select a surrogate
besides CO.
The petitioner (Sierra Club) requested that the EPA remove the CO
standard as a surrogate for organic HAP and instead adopt a numeric
limit for these HAP, because CO is not an appropriate surrogate. The
EPA is denying the request for reconsideration on this issue. While the
EPA disagrees with the petitioner's argument regarding the suitability
of CO as a surrogate for organic HAP, the petitioner has not
demonstrated that it lacked the opportunity to comment on this issue.
The EPA proposed CO standards as a surrogate for organic HAP and
explained in the proposal the agency's basis for concluding that CO was
an appropriate surrogate. 75 FR at 32018. The EPA received comments on
this issue, including comments stating that CO is not an appropriate
surrogate for organic HAP. Therefore, the EPA is denying the request
for reconsideration.
Issue: Adopt an alternative THC emission standard.
The petitioner (CIBO) requested that the EPA adopt a THC emissions
standard as an alternative to the CO standard. The EPA is denying the
request for reconsideration on this issue. While the EPA disagrees with
the petitioner's argument regarding whether a THC alternative standard
is appropriate as a surrogate for non-dioxin organic HAP, the
petitioner has not demonstrated that it lacked the opportunity to
comment on this issue. The EPA raised in the proposal the possibility
of THC as a surrogate for non-dioxin organic HAP, and explained why the
use of CO as a surrogate was preferable. 75 FR at 32018. In addition,
the EPA did not receive any comments or data during the public comment
period on the proposed rule that would have enabled the agency to
establish a THC alternative standard, including THC emissions data, nor
did the petitioner provide any such data. Therefore, the petition does
not provide substantial support for its argument that the final rule
should be changed. For these reasons, the EPA is denying the petition
for reconsideration on this issue.
Issue: Regulation of Total dioxin/furans exceeds statutory
authority as only 2 compounds are in 112(b)(1).
The petitioners (AISI, ACCCI, AF&PA) alleged that the EPA lacks
statutory authority to regulate total dioxin/furans under CAA section
112, and that the EPA's response in the final rule explaining why it is
issuing a total dioxin/furan standard was not a logical outgrowth of
the proposed rule. The EPA is denying the request for reconsideration
on this issue. First, the EPA disagrees that the final rule is not a
logical outgrowth of the proposal. The EPA proposed emissions standards
for total dioxin/furans and adopted a final emissions standard for the
same pollutant. Therefore, the commenter had the opportunity to provide
its views during the public comment period regarding the EPA's proposed
emissions standard, including its views regarding the EPA's authority
to regulate the pollutant at issue. The fact that the EPA responded to
those comments does not mean that the petitioner lacked the opportunity
to comment--in fact, the petitioner did provide such comments. 76 FR at
15640. For this reason, the EPA is denying the petition for
reconsideration.
Issue: HCl is an inadequate surrogate for all acid gases.
The petitioner (Sierra Club) requested that the EPA remove the HCl
standard as a surrogate for acid gases and instead adopt a numeric
limit for these HAP, because HCl is not an appropriate surrogate. The
EPA is denying the request for reconsideration on this issue. While the
EPA disagrees with the petitioner's argument regarding the suitability
of HCl as a surrogate for acid gases, the petitioner has not
demonstrated that it lacked the opportunity to comment on this issue.
The EPA proposed HCl standards as a surrogate for acid gases and
explained in the proposal the agency's basis for concluding that HCl
was an appropriate surrogate. 75 FR at 32018. While the EPA had
emission data for HCl from hundreds of affected units upon which to
establish standards, the EPA did not have sufficient data on the other
acid gases to do so (hydrogen fluoride, hydrogen cyanide and chlorine).
The petitioner did not refer to any such data and, therefore, the issue
is not of central relevance to the outcome of the final rule.
Therefore, the EPA is denying the request for reconsideration.
Issue: Establish work practice for other organic HAP instead of
using CO as a surrogate.
The petitioners (AMP, JELD-WEN) requested that the EPA adopt a work
practice standard for organic HAP rather than a numeric emissions limit
based on CO as a surrogate for organic HAP. The EPA is denying the
request for reconsideration on this issue. While the EPA disagrees that
a work practice standard is appropriate for such HAP for the
subcategories for which the EPA adopted a numeric CO limit in the final
rule, the petitioners have not demonstrated that they lacked the
opportunity to comment on this issue. The EPA proposed numeric CO
limits rather than a work practice, and the petitioners had the
opportunity to provide their views during the public comment period on
the proposed rule regarding why it believed a work practice standard
should instead be
[[Page 7150]]
finalized. Therefore, the EPA is denying the petition for
reconsideration.
Issue: Allow health based compliance alternatives for HCl, other
acid gases and manganese.
The petitioners (AMP, AF&PA, AHFA, AISI, ACCCI, RPU, CIBO)
requested that the EPA adopt a HBES for HCl and other acid gases as
well as for manganese, pursuant to section 112(d)(4). The petitioners
also requested that the EPA grant reconsideration on this issue to
better address the comments and data submitted during the public
comment period for the proposed rule. The EPA is denying the request
for reconsideration of this issue. The EPA did not propose a HBES for
any pollutants, but did solicit public comment on such standards,
explaining its concerns regarding health-based standards, including the
lack of available data on which to base such standards. 75 FR at 32030.
The EPA received comments addressing those concerns and responded to
them in the final rule. 76 FR at 15642. Therefore, the petitioners have
not demonstrated that it lacked the opportunity to comment on this
issue. Further, the EPA received no data during the public comment
period for the proposed rule on which it could base a HBES for HCl,
other acid gases or manganese. Therefore, the petitions do not provide
substantial support to demonstrate that the final rule should be
changed. For these reasons, the EPA is denying the petition for
reconsideration.
Issue: Provide additional compliance alternatives according to
Executive Order 13563 (additional subcategories and HBES).
The petitioner (AHFA) requested that the EPA provide additional
compliance alternatives in the final rule pursuant to Executive Order
13563 (Improving Regulation and Regulatory Review), including HBES. The
EPA is denying the request for reconsideration on this issue because it
is not of central relevance. First, nothing in Executive Order 13563
affects the EPA's discretion to establish HBES under the CAA.
Additionally, the petition does not provide any information to address
our concerns regarding HBES or data to establish such standards.
Issue: Remove energy assessment requirements.
The petitioners (AHFA, AISI, ACCCI, API, NPRA, AIF, CIBO, AF&PA,
U.S. Sugar) requested that the EPA remove from the final rule the
requirement that existing sources conduct an energy assessment. The EPA
is denying the request for reconsideration on this issue. The EPA
proposed an energy assessment requirement as a beyond-the-floor
standard, and petitioners commented on that proposal. The EPA addressed
those comments in the final rule, and petitioners have not demonstrated
that they lacked the opportunity to comment on whether the EPA should
require an energy assessment, including the EPA's legal authority to do
so. 76 FR at 15631. Therefore, the EPA is denying the petition for
reconsideration. The EPA continues to believe that an energy assessment
is not only authorized by the CAA but required as a cost-effective
beyond-the-floor standard in accordance with section 112(d)(2).
Issue: Require energy assessment to be conducted every 5 years.
The petitioner (Washington Dept. of Ecology) requested that the EPA
require more frequent energy assessments. The EPA proposed a one-time
assessment (75 FR at p. 32036) and the petitioner has not demonstrated
it lacked the opportunity to comment on the frequency of the assessment
requirement. Therefore, the EPA is denying the petition.
Issue: Modify cost analysis to include potential fuel savings from
implementing assessment findings.
The petitioners (AIE, USCHPA) requested that the EPA modify its
cost impacts analysis to include potential fuel savings from
implementing energy assessment findings. The EPA is denying the
petition. The impacts analysis, including specific mention of how cost
savings for energy assessments were handled quantitatively, was
explained in the proposal (see 75 FR 32026), and the petitioner
therefore had the opportunity to comment on this issue. For this
reason, the EPA is denying the petition for reconsideration on this
issue.
Issue: Reconsider definition of ``cost effective.''
The petitioners (AIE, USCHPA) requested that the EPA reconsider the
definition of ``cost-effective'' in the final rule. The EPA is denying
the request for reconsideration on this issue. The EPA proposed to
define cost-effective energy conservation measures as any measure with
return of investment period of two years or less. 75 FR at 32036. The
petitioners have not demonstrated it lacked the opportunity to comment
on the proposed definition. Therefore, the EPA is denying the petition
for reconsideration.
Issue: Establish work practice for other organic HAP instead of
using CO surrogate.
The petitioners (AMP, JELD-WEN) requested that the EPA establish
work practice standards for controlling organic HAP instead of using CO
as a surrogate for organic HAP and establishing CO emission limits. The
EPA is denying the request for reconsideration on this issue. Use of CO
as a surrogate for organic HAP was subject to notice and comment. (75
FR 32018, 75 FR 32041). Responses to comment on this topic were
provided in RTC document, Volume 2, EPA-HQ-OAR-2002-0058-3289, see
section ``Choice of Regulated Pollutants: THC vs. CO vs. Other Organic
HAP''.
Issue: Provide alternative format for units of measure for CO
emission limits to allow sources to use their existing monitoring
equipment.
The petitioners (UARG, CIBO) requested that the EPA provide an
alternative format (ppm at X percent CO2) for units of
measure for CO emissions in addition to ppm at 3 percent oxygen. The
EPA is denying the petition because the petitioners do not demonstrate
that it was impracticable to comment on this issue. The format for
units of measure for the limits was provided in the proposed rule, and
petitioners could have commented on whether the proposed units were
appropriate.
Issue: New source emission limits are unachievable and the EPA
should collect additional fuel variability data from top performing
units to adjust the limits.
The petitioner (AF&PA) requested that the EPA adjust the emissions
limits for new sources by collecting additional data from the best
performing units that they believed would result in increased
variability. The petitioners have not demonstrated that they lacked the
opportunity to comment. We proposed standards based on the data we had,
including data collected during the ICR process in which petitioners
participated, and that data were available for public review.
Therefore, petitioners could have commented on this issue. Second, the
CAA requires that we base the standards on the sources for which we
have emissions information. Petitioners are always free to provide more
information to us and the EPA specifically requested new data at each
stage of the rulemaking to support the development of emission limits
for each subcategory. (75 FR 32041, 76 FR 28663, 76 FR 80612). The EPA
has incorporated revised data corrections or new data submittals in its
analysis for the final rule. The EPA is denying the request for
reconsideration.
Issue: Adjust the methodology for computing MACT floors to address
statistical errors and variability concerns.
The petitioners (AISI, ACCCI, AF&PA) requested that the EPA adjust
the
[[Page 7151]]
methodology for computing MACT floors to address statistical errors and
variability concerns, including: (1) Dataset reflects the ``best of the
best'' units; (2) misapplication of statistical formulae to address
distribution, confidence limits, and variability; and (3) failure to
address variability in emissions from one unit over time. The methods
used to compute the MACT floors were subject to notice and comment.
Where new data or data corrections have been submitted that might alter
data distributions, identifying best performers or application of fuel
variability factors, these changes have been made in the final rule,
but the general methodology remains the same. See Solite Corp. v. EPA,
952 F.2d 473, 485 (D.C. Cir. 1991) (public had sufficient notice of
final rule threshold calculations where methodology did not change
significantly from proposed rule). The EPA explained the MACT floor
methodology in the proposed rule, and addressed comments received on
the proposed methodology in the final rule (75 FR 32019-26, 32027-29,
76 15621-30, 76 FR 80614). Therefore, the EPA is denying the request
for reconsideration.
Issue: Modify the basis for ranking the top performing units.
The petitioner (WEPCO) requested that the EPA modify the basis for
ranking the top performing units, especially for new units, according
to the average performance of the unit. The EPA is denying the
petition. The methods used to rank units to establish the MACT floors
were subject to notice and comment. The EPA explained its methodology
in the proposed rule and addressed comments received on the ranking of
data for computing the MACT floor in the final rule (75 FR 32019-26,
32027-29, 76 FR 15627).
Issue: Do not use a pollutant-by-pollutant approach to establish
MACT floors.
The petitioners (AISI, ACCCI, AF&PA) requested that the EPA not use
a pollutant-by-pollutant approach to establish MACT floors. The
petitioners stated that this method is not a reasonable interpretation
of Section 112(d)(3) of the CAA and that MACT floors should reflect
levels achieved in practice, not aspirational controls. The EPA is
denying the petition for reconsideration on this issue because it does
not demonstrate that it was impracticable to comment on the issue. The
EPA proposed MACT floors based on the pollutant-by-pollutant
methodology, and therefore petitioners could, and in fact did, provide
comments opposing this approach. See 75 FR 32021, 32029. The EPA
addressed comments received on this approach in the final rule (76 FR
15621-23). Therefore, the EPA is denying the petition.
Issue: Revise approach to establish MACT floors where there is non-
detect data.
The petitioner (Sierra Club) requested that the EPA not use the
approach it used in the final rule based on the representative
detection level (RDL) to establish MACT floors because it does not
reflect actual emissions of any source within the subcategory. Further,
the petitioner questioned the basis of the selected detection level,
and whether or not other variability adjustments (e.g., UPL analysis)
sufficiently account for measurement imprecision. The EPA is denying
the petition. The three times representative detection level approach
was subject to notice and comment. The EPA explained its rationale for
this approach in the proposed rule (75 FR 32021) and responded to
comments received in the final rule (76 FR 15623, 76 FR 80611).
Issue: The approach used to set MACT floor limits for dioxin/furan
emissions is flawed and the EPA should establish an isomer-specific
approach.
The petitioner (WEPCO) requested that the EPA establish an isomer-
specific approach for dioxin/furan emissions because the three times
detection level approach for dioxin/furan emissions is flawed. The EPA
is denying the petition. This approach was subject to notice and
comment. Rationale and responses to comments on this approach were
provided at (75 FR 32021, 32041, 76 FR 15623). Further, the methods for
establishing a representative detection level for dioxin/furan have
been revised to account for the sensitivity of individual isomers, see
rationale provided at (76 FR 80606).
Issue: Incorporate a fuel variability factor for PM based on the
ash content of the fuel used by best performing units.
The petitioners (WEPCO, CIBO) requested that the EPA incorporate a
fuel variability factor for PM based on the ash content of the fuel
used by best performing units. The MACT floor methodology was explained
in the June 4, 2010 proposal which included fuel variability factors
that did not reflect the ash content of the fuel. Therefore, the
petitioner could have commented recommending that the EPA do so, and,
in fact, comments were provided on this issue. The EPA is denying the
petition for reconsideration on this issue because it does not
demonstrate that it was impracticable to comment on the issue.
Responses to comment on this topic were provided in RTC document,
Volume 1, EPA-HQ-OAR-2002-0058-3289, see section ``MACT Floor
Methodology: Fuel Analysis Variability''.
Issue: Allow energy assessors to determine the time needed to
conduct assessment.
The petitioner (Washington Dept. of Ecology) requested that the EPA
allow the energy assessor to determine the time needed to conduct the
energy assessment. The EPA is denying the petition. The duration of
energy assessments was subject to notice and comment and the duration
remains up to the affected source. Specific concerns with maximum
duration requirements included in the March 21, 2011 final rule were
clarified in the December 23, 2011 proposed notice of reconsideration.
(76 FR 80615)
Issue: The unit designed to burn gas 1 subcategory should allow for
limited use of liquid fuels.
The petitioners (ACC, CEG, API, NPRA) requested that the EPA allow
units in the Gas 1 subcategory for limited use of liquid fuels; for
example, units with a federally enforceable permit on back up fuels or
units burning 10 percent or less of its heat input from liquid fuels
should qualify as gas 1 units. The EPA is denying the petition because
it does not demonstrate that it was impracticable to comment on the
issue. The EPA proposed definitions of the various subcategories, and
petitioners had the opportunity to comment on those definitions,
including the proposed definition of the Gas 1 subcategory which did
allow for the limited use of liquid fuels. The EPA addressed comments
received on this issue in the final rule (76 FR 15620).
Issue: The unit designed to burn gas 1 subcategory should
automatically include other gaseous fuels such as petrochemical process
gas and landfill gas.
The petitioners (ACC, AIF, WM) requested that the EPA redefine the
unit designed to burn gas 1 subcategory to automatically include other
gaseous fuels such as petrochemical process gas and LFG, especially
when the LFG is routed to a treatment system prior to use or sale. The
EPA proposed definitions of units designed to burn gas 1 and units
designed to burn gas 2 (other), and therefore the petitioner had the
opportunity to comment on these definitions and to recommend that other
gases be included in the definition of the Gas 1 subcategory (75 FR
32017, 32065). The EPA addressed comments received on this issue in the
final rule (76 FR 15638). Therefore, the EPA is denying the petition.
[[Page 7152]]
Issue: Reconsider the emission standards established for the unit
designed to burn gas 2 subcategory.
Petitioners (AIF, CIBO, WM, CEG) requested that the EPA reconsider
the emission standards for the unit designed to burn gas 2 subcategory
in light of what they feel was a limited dataset and lack of data from
a diverse set of fuel types. The EPA is denying the petition. The MACT
floor methodology was open to notice and comment in the June 4, 2010
proposal. The EPA proposed emissions standards for this subcategory and
the petitioners had an opportunity to comment on the proposed standards
and the data on which the standards were based. The EPA further notes
that the CAA requires that the MACT standards be based on the best
performing sources for which the Administrator has emissions
information.
Issue: Adjust the ``metal process furnaces'' subcategory definition
to include any gas-fired process furnace.
The petitioners (AISI, ACCCI) requested that the EPA adjust the
``metal process furnaces'' subcategory definition to include any gas-
fired process furnace. The EPA is denying the petition. The definition
of the subcategory for metal process furnaces was subject to notice and
comment. (75 FR 32064, 76 FR 15620).
Issue: The designed to burn rationale for subcategorization is
arbitrary.
The petitioner (Sierra Club) alleged that the designed to burn
rationale for subcategorization is arbitrary, especially considering
the large number of co-fired units in the inventory. The EPA proposed
subcategories based on boiler design, and the petitioner has not
demonstrated that it was impracticable to comment on the issue. In
fact, the petitioner did submit comments on the proposed rule opposing
the EPA's proposed subcategorization approach. Therefore, the EPA is
denying the petition.
Issue: The EPA should consider exempting units from NSR.
The petitioners (MSU, PSU, Purdue, Citizens Thermal Energy)
requested that the EPA consider exempting units from NSR who switch
fuels, install pollution controls, or construct energy efficiency
projects to meet the requirements of this rule because complying with
the rule requirements will trigger NSR. The EPA is denying the
petition. The applicability of NSR is outside the scope of this
rulemaking. Moreover, it was not impracticable to comment on this issue
during the 2011 rulemaking, in fact, comments were submitted on this
issue, to which the EPA responded. See RTC document, Volume 2, EPA-HQ-
OAR-2002-0058-3289, DCN EPA-HQ-OAR-2002-0058-2729.1, excerpt 17.
Issue: Remove the 10 percent penalty for sources opting to use the
emission averaging compliance alternative.
The petitioners (AMP, MSU, PSU, Purdue, RPU, U.S. Sugar, Citizens
Thermal Energy) requested that the EPA remove the 10 percent penalty
for sources opting to use the emission averaging compliance
alternative. The EPA is denying the petition. The EPA proposed an
emissions averaging approach that included the 10 percent adjustment
factor. (75 FR 32035) Therefore, the petition does not demonstrate that
it was impracticable to comment on this issue. Responses to comment on
this topic were provided in RTC document, Volume 2, EPA-HQ-OAR-2002-
0058-3289, see section ``Emissions Averaging.''
Issue: Allow emissions averaging across subcategories.
The petitioners (MSU, PSU, Purdue, RPU, Citizens Thermal Energy)
requested that the EPA allow emissions averaging across subcategories.
The EPA is denying the petition. The EPA proposed an emissions
averaging approach that did not allow averaging across subcategories,
and petitioners therefore had the opportunity to comment recommending
that the EPA allow such averaging. Responses to comment on this topic
were provided in RTC document, Volume 2, EPA-HQ-OAR-2002-0058-3289, DCN
EPA-HQ-OAR-2002-0058-3213.1, excerpt 175.
Issue: Allow a source's actual heat input instead of the maximum
design heat input to be used in the emissions averaging provisions.
The petitioner (CIBO) requested that the EPA allow a source's
actual heat input instead of the maximum design heat input to be used
in the emissions averaging provisions of the final rule. The EPA
proposed an emissions averaging approach that was based on the maximum
rated heat input capacity, and petitioners therefore had the
opportunity to comment recommending that the EPA base the averaging on
actual heat input. Therefore, the EPA is denying the petition.
Issue: Reduce stack testing frequency to once every five years to
reduce burden on facilities.
The petitioners (ACC, CIBO, JELD-WEN) requested that the EPA reduce
stack testing frequency to once every 5 years and rely on the extensive
set of continuous parameter monitoring in order to reduce burden on
facilities. The EPA is denying the petition. The EPA proposed to
require stack testing every year. The petition does not demonstrate
that it was impracticable to comment on this issue, and the petitioners
could have submitted comments requesting less frequent stack testing.
Issue: Incorporate detailed fuel sampling procedures using
incorporation by reference mechanisms instead of detailing sampling
procedures in the regulatory language.
The petitioner (CIBO) requested that the EPA incorporate detailed
fuel sampling procedures using incorporation by reference mechanisms
and citing credible literature (e.g., American Society for Testing and
Materials) instead of detailing sampling procedures in the regulatory
language since sampling procedures are subject to change over time. The
EPA is denying the petition because the petitioner has not demonstrated
that it was impracticable to comment on this issue. The EPA proposed
fuel sampling procedures in the regulatory text in the June 4, 2010
proposal, and the petitioner therefore had the opportunity to comment
recommending its preferred approach.
Issue: Remove the advanced submittal requirement for site-specific
fuel monitoring plans before each analysis.
The petitioner (UARG) requested that the EPA remove the advanced
submittal requirement for site-specific fuel monitoring plans before
each analysis, especially if monthly frequency is maintained. If the
fuel monitoring plan requirement remains, the petitioner requests that
the EPA remove the requirement to report things that might change, such
as unanticipated fuel use (based on unanticipated fuel changes). The
EPA is denying the petition and disagrees with the commenter. First,
the EPA proposed a fuel monitoring plan, and petitioners had the
opportunity to comment on the plan requirement. The final rule requires
submittal of a fuel monitoring plan 60 days before demonstrating
initial compliance. The rule does not require re-submittal of this plan
before each monthly analysis, see 40 CFR section 63.7521(b)(1).
Issue: Allow EPA Method 5B to demonstrate compliance with PM
emission limits.
The petitioner (UARG) requested that the EPA allow EPA Method 5B to
demonstrate compliance with PM emission limits. The EPA is denying the
petition because it does not demonstrate that it was impracticable to
comment on this issue. The EPA proposed methods to demonstrate
compliance in the June 4, 2010 proposal and did not propose to allow
Method 5B for PM compliance demonstrations. Therefore, the petitioner
had the opportunity to submit comments recommending that the EPA allow
the use of this method. For this
[[Page 7153]]
reason, the EPA is denying the petition on this issue.
Issue: Remove or make references to Methods 2, 2F, 2G and 4
optional.
The petitioner (UARG) requested that the EPA remove or make
references to EPA Methods 2, 2F, 2G and 4 optional. The EPA is denying
the petition because it does not demonstrate that it was impracticable
to comment on this issue. The EPA proposed methods to demonstrate
compliance in the June 4, 2010 proposal and did not propose to make EPA
Methods 2, 2F, 2G and 4 optional. Therefore, the petitioner had the
opportunity to submit comments recommending that the EPA make the use
of these methods optional. For this reason, the EPA is denying the
petition on this issue.
Issue: Allow sources to petition for alternative PM monitoring
requirements based on source-specific limitations.
The petitioner (CEG) requested that the EPA allow sources to
petition for alternative PM monitoring requirements based on source-
specific limitations (e.g., common stacks with more than one
subcategory). The EPA is denying this petition because it is not of
central relevance to this rulemaking. The General Provisions at 40 CFR
63.8 allow sources to petition the EPA for alternative monitoring
plans. Therefore, no such provision is needed in this final rule.
Issue: Allow sources with overlapping CEMS regulations to comply
with existing QA/QC plans or 40 CFR part 75 Appendices A and B.
The petitioners (CIBO, CMI) requested that the EPA allow sources
with overlapping CEMS regulations to comply with existing QA/QC plans
or 40 CFR part 75 Appendices A and B. The EPA is denying this petition
because it is not of central relevance to this rulemaking.
Issue: No justification or discussion was provided on why the EPA
selected 12 hours as the averaging time period and also why the EPA
selected block averages instead of rolling averages.
The petitioner (Sierra Club) alleges that the EPA provided no
justification or discussion explaining why the EPA selected 12 hours as
the averaging time period and why the EPA selected block averages
instead of rolling averages for parameter monitor. The petitioner
requested that the EPA clarify that the averaging times for continuous
parameter monitoring should be the same as the averaging times during
the most recent performance test. Averaging times were open to notice
and comment in the June 4, 2010 proposal. In the June 2010 proposal, we
required that parameters be set based on 4-hour block averages during
the compliance test, and that continuous compliance be demonstrated by
monitoring 12-hour block average values for most parameters. We
selected this averaging period to reflect operating conditions during
the performance test to ensure the control system is continuously
operating at the same or better level as during a performance test
demonstrating compliance with the emission limits. Therefore, the EPA
is denying the petition.
Issue: The EPA position regarding treatment of ``out-of-control''
and ``maintenance'' periods as deviations is not supported or
explained.
The petitioner (UARG) alleges that the EPA position regarding
treatment of ``out-of-control'' and ``maintenance'' periods as
deviations is not supported or explained. The petitioner requested that
the EPA revise the definition of ``deviation'' to be consistent with
how deviation is treated with respect to CO CEMS and CPMS. The EPA is
denying the petition. The definition of deviations was open to notice
and comment in the June 4, 2010 proposal.
Issue: Require checks of pressure monitoring taps only if reading
is abnormal.
The petitioner (CMI) requested that the EPA require checks of
pressure monitoring taps only if reading is abnormal. The requirement
to check pressure tap pluggage daily was open to notice and comment in
the June 2010 proposal. In addition, the EPA is denying this petition
because it is not of central relevance to this rulemaking.
Issue: The EPA has not sufficiently correlated emission limits to
operating parameters and should not set enforceable limits on maximum
and minimum control device operating parameters.
The petitioners (UARG, AMP, CIBO) alleges that the EPA has not
sufficiently correlated emission limits to operating parameters and
requested the EPA not to set enforceable limits on maximum and minimum
control device operating parameters. One petitioner (CIBO) requested
that the rule should allow sources to set their own ESP secondary
voltage requirement based on load and coal quality since power
consumption by an ESP is influenced by factors other than operating
load, including ESP design, amount of PM collected, and resistivity of
the PM. Other petitioners (UARG and AMP) also indicate that the limits
set on control devices inhibit the flexibility to operate control
devices with a margin of safety. The EPA is denying the petition.
Operating limits were open to notice and comment in the June 4, 2010
proposal.
Issue: The EPA should delay incorporating PS 17 in this rule until
the revisions for PS 17 are completed.
The petitioner (UARG) requested that the EPA delay incorporating PS
17 in this rule, which outlines how to select and install CPMS, until
the revisions for PS 17 are completed.
The EPA is denying this petition. The final rule did not
incorporate PS 17, or any other PS, in the provision regarding
selection and installation of CPMS and ongoing quality assurance of
data from CPMS. Comments related to revising PS 17 are outside the
scope of this rulemaking. (RTC document, Chapter 11, EPA-HQ-OAR-2002-
0058-3289, DCN EPA-HQ-OAR-2002-0058-2960.1, excerpt 150).
Issue: The EPA should not set an enforceable operating limit on
opacity.
The petitioner (UARG) alleged that there is insufficient
correlation between opacity and PM emissions and requested that the EPA
not set an enforceable operating limit on opacity. The EPA is denying
the petition. The EPA proposed opacity limits in the June 4, 2010
proposal and the petitioner therefore had the opportunity to comment on
the proposed limits, including comments requesting that no limit be
established.
Issue: Update outdated BLDS Guidance.
The petitioner (UARG) requested that the EPA update the outdated
BLDS Guidance that is currently incorporated by reference. The EPA is
denying this petition. The current guidance document is the most recent
guidance available and comments related to revising the guidance
document are outside the scope of this rulemaking. (RTC document,
Chapter 11, EPA-HQ-OAR-2002-0058-3289, DCN EPA-HQ-OAR-2002-0058-2997.1,
excerpt 10).
Issue: The EPA should reconsider emission limits for HCl on coal-
fired boilers using a hot-side ESP for particulate control.
The petitioners (MSU, PSU, Purdue, Citizens Thermal Energy)
requested that the EPA reconsider emission limits for HCl on coal-fired
boilers using a hot-side ESP for particulate control. The petitioners
are unaware of any HCl control devices that are compatible with a hot-
side ESP. The EPA is denying the petition. The basis for
subcategorization was subject to notice and comment. The EPA did not
propose a separate subcategory for such units, and the petitioner could
have commented recommending that the agency do so. (75 FR 32012, 76 FR
15617-18, 76 FR 80607) Further, the EPA disagrees with the petitioner
that the subcategories
[[Page 7154]]
could be based on the level of controls installed on the unit.
Issue: The EPA should change electronic reporting requirements to
avoid WebFIRE and ERT shortcomings.
The petitioner (UARG) requested that the EPA change the electronic
reporting requirements to avoid WebFIRE and ERT shortcomings. The
petitioner requested that to meet the EPA's obligations under the
Paperwork Reduction Act the EPA specify each individual data item
requested in the ERT. The petitioner also requests that the EPA explain
how the ERT electronic signature mechanisms will meet the requirements
of the Cross-Media Electronic Reporting Rule.
The EPA is denying the petition because it does not demonstrate
that it was impracticable to comment on this issue. The EPA proposed to
require the use of the ERT and WebFIRE, and the petitioner therefore
had the opportunity to comment on any concerns with the proposed
approach.
Issue: Eliminate gas curtailment notification requirements or
adjust the frequency of these notifications to be consistent with the
reporting requirements in the Title V program.
The petitioner (AIF) requested that the EPA eliminate the gas
curtailment notification requirements or adjust the frequency of these
notifications to be consistent with the semi-annual reporting
requirements in the Title V program. The EPA is denying the petition.
Reporting requirements were open to notice and comment in the June 4,
2010 proposal.
Issue: Allow facilities to become area or synthetic minor sources
instead of installing controls.
The petitioner (GPSP) requested that the EPA allow facilities to
become area or synthetic minor sources instead of installing controls.
The EPA is denying the petition. Whether or not sources elect to become
area or synthetic minor sources is not of central relevance to this
rulemaking, as nothing in this rule affects whether or how a source can
become a synthetic minor source (RTC document, EPA-HQ-OAR-2002-0058-
3289, Volume 1, DCN EPA-HQ-OAR-2002-0058-3176.2, excerpt 4).
VI. Impacts of This Final Rule
A. What are the incremental air impacts?
Table 4 of this preamble illustrates, for each basic fuel
subcategory, the total emissions reductions achieved by the final
amended rule (i.e., the difference in emissions between a boiler or
process heater controlled to the amended floor level of control and
boilers or process heaters at the current baseline) for new and
existing sources. Nationwide emissions of selected HAP (i.e., HCl, HF,
mercury, metals, and VOC) will be reduced by 44,300 tpy. This is an
incremental increase of 4,000 tpy in HAP reductions compared to the
estimates in the March 2011 final rule. This increase is due mainly to
changes in the inventory (336 units were added since the March 2011
inventory). Excluding the changes in the inventory, the amendments to
the regulatory provisions themselves resulted in a decrease of 1,100
tpy of estimated reductions, part of this incremental reduction in HAP
is contributed to edits to the baseline emission data received since
the March 2011 final rule, as well as changes to the subcategories and
emission limits as a result of this amended rule. The amendments to the
final rule are expected to result in an additional 4,600 tpy of
reductions in HCl emissions. The amendments are also expected to have a
modest effect on mercury, estimated to range from a slight decrease of
0.12 tpy up to a slight increase of 0.96 tpy in emission reductions as
a result of the changes to the regulatory requirements. Reductions in
emissions of filterable PM will decrease by 18,500 tpy due to the final
amended rule. Reductions in emissions of non-mercury metals (i.e.,
antimony, arsenic, beryllium, cadmium, chromium, cobalt, lead,
manganese, nickel, and selenium) will decrease by 260 tpy. In addition,
the amendments are estimated to result in an additional 50,100 tpy of
reductions in SO2 emissions. A discussion of the methodology
used to estimate emissions, emissions reductions, and incremental
emission reductions is presented in ``Revised (August 2012) Methodology
for Estimating Cost and Emission Impacts for Industrial, Commercial,
and Institutional Boilers and Process Heaters NESHAP--Major Source'' in
the docket.

reductions.
[[Page 7155]]
B. What are the incremental water and solid waste impacts?
The EPA estimated the additional water usage that would result from
installing wet scrubbers to meet the amended emission limits for HCl
would be 556 million gallons per year for existing sources compared to
the current baseline. In addition to the increased water usage, an
additional 160 million gallons per year of wastewater would be produced
for existing sources. Only half of these incremental changes are due to
changes in the regulatory provisions. The other half is due to changes
in the number of identified existing units and projected new units. The
annual costs of treating the additional wastewater are $1.2 million.
These additional costs are accounted for in the incremental control
cost estimates.
The EPA estimated the additional solid waste that would result due
to the amendments to be 138,000 tpy, with nearly all due to changes in
the regulatory provisions. Solid waste is generated from flyash and
dust captured in PM and mercury controls as well as from spent carbon
that is injected into exhaust streams or used to filter gas streams.
The costs of handling the additional solid waste generated are $5.8
million. These costs are also accounted for in the incremental control
costs estimates.
A discussion of the methodology used to estimate incremental
impacts is presented in ``Revised (August 2012) Methodology for
Estimating Cost and Emission Impacts for Industrial, Commercial, and
Institutional Boilers and Process Heaters NESHAP--Major Source'' in the
docket.
C. What are the incremental energy impacts?
The EPA estimated that the March 2011 final rule would result in an
increase of about 1.4 billion kWh/yr in national energy usage from the
electricity required to operate control devices, such as wet scrubbers,
electrostatic precipitators and fabric filters which are expected to be
installed to meet the final rule. The amendments are expected to
decrease energy usage by a net 143 million kWh/yr compared to the March
2011 rule. These reductions are driven by the regulatory provisions of
these amendments. Additionally, the EPA expects these amendments will
result in a decrease of 4.4 million MMBtu/yr in fuel savings, compared
with the estimates in the March 2011 final rule.
D. What are the incremental cost impacts?
For these final amendments, we estimated the incremental difference
between the national costs impacts for the final amended rule and the
March 2011 final rule. First, we determined the control measures, work
practices, and monitoring and testing requirements that would be
required by boilers and process heaters located at major source
facilities to comply with the final amended rule. To estimate the
national cost impacts of the final amended rule for existing sources,
we used the identical methodology used to estimate the cost impacts for
the March 2011 final rule with one exception. In this revised analysis,
it was assumed that several liquid fuel units that reported natural gas
firing capability would switch to natural gas as a compliance option
instead of installing add-on controls to demonstrate compliance with
the emission limits. Thus, the only costs to these units would be the
tune-up work practice costs. A discussion of the methodology used to
estimate cost impacts is presented in ``Revised (August 2012)
Methodology for Estimating Cost and Emission Impacts for Industrial,
Commercial, and Institutional Boilers and Process Heaters NESHAP--Major
Source'' in the docket.
The resulting total national cost impact of the final amended rule
is $4.7 billion in capital expenditures and $1.5 billion per year in
total annual costs, considering fuel savings. The total capital
expenditures are slightly lower than estimated for the March 2011 final
rule, but the total annual costs are slightly higher than estimated for
the March 2011 final rule. See 76 FR 15651. The total capital and
annual costs include costs for control devices, work practices, testing
and monitoring.
In order to determine the incremental cost impacts of the amended
requirements and emission limits, we first estimated the cost impacts
of the additional existing boilers and process heaters added to the
Boiler MACT inventory database since promulgation of the March 2011
final rule and the revised number of new boilers and process heaters
that could be potentially constructed. Since the March 2011 final rule,
we became aware of 72 major source facilities that were not previously
in the Boiler MACT inventory database. Adding the boilers and process
heaters located at these newly identified major source facilities
resulted in 73 additional coal-fired units, 32 additional biomass-fired
units, 82 additional oil-fired units, and 149 additional gas-fired
units. Our revised number of new boilers and process heaters included
82 additional biomass units, 1,728 additional gas 1 units and 13 fewer
liquid units.
The resulting cost impact for these additional existing and new
boilers and process heaters is $1.0 billion in capital expenditures and
$0.31 billion per year in total annual costs, considering fuel savings.
Therefore, discounting the added costs for the additional boilers
and process heaters included in the costs analysis, the estimated
incremental cost impacts for these amended requirements on existing and
new boilers and process heaters are $1.0 billion in capital
expenditures and $0.13 billion per year in total annual costs less than
the costs estimated in the March 2011 rule.
Table 5 of this preamble shows the total capital and annual cost
impacts of the final amended rule for each subcategory. Costs include
testing and monitoring costs, but not recordkeeping and reporting
costs.

\a\ Total annualized costs for new units do not account for fuel savings since no fuel savings are estimated in the first year for new units.
Potential control device cost savings and increased recordkeeping
and reporting costs associated with the emissions averaging provisions
in the final rule are not accounted for in either the capital or
annualized cost estimates.
A discussion of the methodology used to estimate cost impacts is
presented in ``Revised (August 2012) Methodology for Estimating Cost
and Emission Impacts for Industrial, Commercial, and Institutional
Boilers and Process Heaters NESHAP--Major Source'' in the docket.
E. What are the economic impacts?
The EPA analyzed the economic impacts of this final amended rule
using the methodology that was discussed in the March 2011 final rule
RIA and in the preamble to the March 2011 final rule. See FR 76 15651.
The market impact results are very similar to the results presented in
the March 2011 final rule and the RIA. The agency's economic model
suggests the average national price increases for industrial sectors
are less than 0.01 percent, while average annual domestic production
may fall by less than 0.01 percent.
Because of higher domestic prices, imports slightly rise. The
results for sales tests for small businesses were somewhat reduced than
those calculated for the March 2011 final rule. For the sales tests
using small companies identified in the Combustion Survey, the mean
cost to receipts dropped from 4 percent in the RIA to 3 percent for
this final amended rule and the median was 0.2 percent for the RIA and
also 0.2 percent for this final amended rule. The number of parent
companies with sales tests exceeding 3 percent dropped from 8 in the
RIA to 5 for this final amended rule. There was no change in the
results for small public entities. Median cost is still about $1.1
million and representative small major public entities would have cost-
to-revenue ratios above 10 percent. The change in employment estimates
between the RIA and the final amended rule is minimal. In the RIA for
the March 2011 final rule, we estimated employment changes ranging
between -3,100 to +6,500 employees, with a central estimate of +1,700.
For this final amended rule we estimate employment changes ranging
between -2,600 to +5,400 employees, with a central estimate of +1,400.
These estimated annual employment changes compared to the baseline
employment, and are for the time period for which the annualized cost
applies (2015 to 2029).
F. What are the benefits of this final rule?
We calculated health benefits using the methodology described in
the RIA prepared for the March 21, 2011 final rule. We incorporated the
revised emission reductions estimated for this reconsideration final
rule into the analysis. We were unable to estimate the benefits from
reducing exposure to HAP and ozone, ecosystem impairment and visibility
impairment, including reducing 180,000 tons of carbon monoxide, 39,000
tons of HCl, 500 tons of HF, 2,500 tons of other metals and 3,100 to
5,300 pounds of mercury. Please refer to the full description of the
unquantified benefits as well as technical details of the analysis and
its limitations and uncertainties in the final Boiler RIA (March 2011).
These monetized benefits are approximately 23 percent higher than the
March 2011 final rule benefits due to the increase in SO2
emission reductions associated with the additional units affected by
the rule and the revised HCl limit. We estimate the total monetized
benefits of this final regulatory action to be $27 billion to $67
billion at a 3 percent discount rate and $25 to $61 billion at a 7
percent discount rate. All estimates are for the implementation year
(2015) in 2008$. A summary of the monetized benefits estimates at
discount rates of 3 percent and 7 percent is provided in Table 6 of
this preamble. A summary of the avoided health incidences is provided
in Table 7 of this preamble.

\a\ All estimates are for the implementation year (2015), and are rounded to two significant figures so numbers
may not sum across rows. All fine particles are assumed to have equivalent health effects because the
scientific evidence is not yet sufficient to allow differentiation of effect estimates by particle type.
Benefits from reducing hazardous air pollutants (HAP) are not included. These estimates do not include energy
disbenefits valued at $24 million (using a 3 percent discount rate). These benefits reflect existing boilers
and new boilers anticipated to come online by 2015.
\b\ There are some slight differences in the emission reductions used in the RIA and those used in the air
impacts section of this preamble due to some late changes in the data that were received after the RIA was
completed. Refer to the memoranda ``Revised (August 2012) Methodology for Estimating Cost and Emission Impacts
for Industrial, Commercial, and Institutional Boilers and Process Heaters NESHAP--Major Source'' for a
discussion of the differences.

G. What are the incremental secondary air impacts?
For units adding controls to meet the amended emission limits, we
anticipate very minor secondary air impacts. The combustion of fuel
needed to generate additional electricity would yield slight increases
in emissions, including NOX, CO, PM and SO2 and
an increase in CO2 emissions. Since NOX and
SO2 are covered by capped emissions trading programs and
methodological limitations prevent us from quantifying the change in CO
and PM, we do not estimate an increase in secondary air impacts for
this final rule from additional electricity demand. We do estimate
greenhouse gas impacts, which result from increased electricity
consumption, to be 859,200 tpy from existing units and 79,700 tpy from
new units. This is 19,200 tpy less than the estimated greenhouse gas
impacts associated with the March 2011 final rule.
VII. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review
Under section 3(f)(1) of Executive Order 12866 (58 FR 51735,
October 4, 1993), this action is an ``economically significant
regulatory action'' because it is likely to have an annual effect on
the economy of $100 million or more or adversely affect in a material
way the economy, a sector of the economy, productivity, competition,
jobs, the environment, public health or safety, or state, local, or
tribal governments or communities. Accordingly, the EPA submitted this
action to the OMB for review under Executive Orders 12866 and 13563 (76
FR 3821, January 21, 2011) and any changes made in response to the OMB
recommendations have been documented in the docket for this action.
The EPA did prepare a new RIA for this action. The EPA prepared an
assessment of the changes in the costs and benefits of this final rule
compared to the costs and benefits associated with the March 21, 2011,
final rule. Overall, the costs and impacts are estimated to be similar
to the costs and impacts associated with the previous final rule,
although the distribution is somewhat different and the number of
affected units in the inventory has increased by about 302 units. When
comparing the costs using only those sources that were part of the
final rule inventory, the costs have decreased. The EPA re-ran the
multimarket model to assess changes in economic impacts, and this
analysis confirmed that the overall economic impacts are similar to the
previous final rule. The benefits are projected to increase by about 20
percent because of the increase in the estimated SO2
reductions. A summary of the costs and benefits of the previous final
rule is provided in the preamble to the previous final rule (see 76 FR
15658) and the detailed analysis for the previous final rule is
provided in the RIA for the previous final rule. In addition, memoranda
are provided in the docket to document the changes in costs, economic
impacts, and benefits associated with this final rule, shown in Table
8.

------------------------------------------------------------------------
\1\ All estimates are for the implementation year (2015), and are
rounded to two significant figures.
\2\ The total monetized co-benefits reflect the human health benefits
associated with reducing exposure to PM2.5 through reductions of PM2.5
precursors such as directly emitted particles, SO2, and NOX and
reducing exposure to ozone through reductions of VOC. It is important
to note that the monetized benefits include many but not all health
effects associated with PM2.5 exposure. Monetized benefits are shown
as a range from Pope et al. (2002) to Laden et al. (2006). These
models assume that all fine particles, regardless of their chemical
composition, are equally potent in causing premature mortality because
the scientific evidence is not yet sufficient to support the
development of differential effects estimates by particle type. These
estimates include the energy disbenefits valued at $24 million (using
the 3 percent discount rate), which do not change the rounded totals.
CO2-related disbenefits were calculated using the ``social cost of
carbon'', which is discussed further in the RIA.
\3\ The methodology used to estimate social costs for one year in the
multimarket model using surplus changes results in the same social
costs for both discount rates.
B. Paperwork Reduction Act
The OMB has approved the information collection requirements
contained in the March 21, 2011 final rule under the provisions of the
Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned OMB
control number 2060-0551. The EPA has updated the supporting statement
to reflect the final inventory and burden estimates associated with
this action since some of the monitoring, recordkeeping and reporting
requirements have changed since the March 21, 2011 final rule. These
revised estimates have been sent to OMB for review and approval.
The information requirements are based on notification,
recordkeeping, and reporting requirements in the NESHAP General
Provisions (40 CFR part 63, subpart A), which are mandatory for all
operators subject to national emission standards. These recordkeeping
and reporting requirements are specifically authorized by section 114
of the CAA (42 U.S.C. 7414). All information submitted to the EPA
pursuant to the recordkeeping and reporting requirements for which a
claim of confidentiality is made is safeguarded according to agency
policies set forth in 40 CFR part 2, subpart B.
This final rule will require maintenance inspections of the control
devices but will not require any notifications or reports beyond those
required by the General Provisions aside from a notification of intent
to commence burning solid waste materials and notification of
alternative fuel use for those units that are in the Gas 1 subcategory
but burn liquid fuels for periodic testing, or during periods of gas
curtailment or gas supply emergencies. The recordkeeping requirements
require only the specific information needed to determine compliance.
The revised annual monitoring, reporting and recordkeeping burden
for this collection (averaged over the first 3 years after the
effective date of the standards) is estimated to be $95.3 million which
is about the same as estimated for the March 2011 final rule. This
includes 323,130 labor hours per year at a total labor cost of $30.6
million per year, and total non-labor capital costs of $64.7 million
per year. This estimate includes initial and annual performance test,
conducting and documenting an energy assessment, conducting fuel
specifications for Gas 1 units, repeat testing under worst-case
conditions for solid fuel units, conducting and documenting a tune-up,
semiannual excess emission reports, maintenance inspections, developing
a monitoring plan, notifications and recordkeeping. Monitoring,
testing, tune-up and energy assessment costs and cost were also
included in the cost estimates presented in the control costs impacts
estimates in section VI.D of this preamble. The total burden for the
federal government (averaged over the first 3 years after the effective
date of the standard) is estimated to be 100,608 hours per year at a
total labor cost of $5.3 million per year. Burden is defined at 5 CFR
1320.3(b).
An agency may not conduct or sponsor, and a person is not required
to respond to, a collection of information unless it displays a
currently valid OMB control number. The OMB control numbers for the
EPA's regulations in 40 CFR are listed in 40 CFR part 9. In addition,
the EPA is amending the table in 40 CFR part 9 of currently approved
OMB control numbers for various regulations to list the regulatory
citations for the information requirements contained in this final
rule.
C. Regulatory Flexibility Act
The RFA generally requires an agency to prepare a regulatory
flexibility analysis of any rule subject to notice and comment
rulemaking requirements under the Administrative Procedure Act or any
other statute unless the agency certifies that the rule will not have a
significant economic impact on a substantial number of small
entities.\1\ The RFA also allows an agency to ``consider a series of
closely related rules as one rule for the purposes of sections'' 603
(initial regulatory flexibility analysis) and 604 (final regulatory
flexibility analysis) in order to avoid ``duplicative action.'' 5
U.S.C. Sec. 605(c). This final rule is closely related to the final
major source rule, which the EPA signed on February 21, 2011. The EPA
prepared a final regulatory flexibility analyses in connection with the
major source rule. Therefore,
[[Page 7159]]
pursuant to Sec. 605(c), the EPA is not required to complete a final
regulatory flexibility analysis for this rule.
---------------------------------------------------------------------------
\1\ Small entities include small businesses, small
organizations, and small governmental jurisdictions. For purposes of
assessing the impacts of today's rule on small entities, small
entity is defined as: (1) A small business according to Small
Business Administration (SBA) size standards by the North American
Industry Classification System category of the owning entity. The
range of small business size standards for the affected industries
ranges from 500 to 1,000 employees, except for petroleum refining
and electric utilities. In these latter two industries, the size
standard is 1,500 employees and a mass throughput of 75,000 barrels/
day or less, and 4 million kilowatt-hours of production or less,
respectively; (2) a small governmental jurisdiction that is a
government of a city, county, town, school district or special
district with a population of less than 50,000; and (3) a small
organization that is any not-for-profit enterprise which is
independently owned and operated and is not dominant in its field.
---------------------------------------------------------------------------
The EPA has been concerned with potential small entity impacts
since it began developing the major source rule. The EPA conducted
outreach to small entities and, pursuant to Sec. 609 of RFA, convened
a Small Business Advocacy Review Panel to obtain advice and
recommendations from small entity representatives.
Pursuant to the RFA, the EPA used the Panel's report and prepared
both an initial regulatory flexibility analysis and a final regulatory
flexibility analysis in connection with the closely related major
source rule. Convening an additional Panel and preparing an additional
final regulatory flexibility analysis would be procedurally duplicative
and is unnecessary given that the issues here are within the scope of
those considered by the Panel. In addition, this final action would
decrease capital and annualized costs on small entities by about 3
percent and 10 percent, respectively, relative to the closely related
final rule.
D. Unfunded Mandates Reform Act
Title II of the UMRA of 1995, 2 U.S.C. 1531-1538, requires federal
agencies, unless otherwise prohibited by law, to assess the effects of
their regulatory actions on state, local and tribal governments and the
private sector. Federal agencies must also develop a plan to provide
notice to small governments that might be significantly or uniquely
affected by any regulatory requirements. The plan must enable officials
of affected small governments to have meaningful and timely input in
the development of the EPA regulatory proposals with significant
Federal intergovernmental mandates and must inform, educate, and advise
small governments on compliance with the regulatory requirements.
Both this rule and the March 21, 2011 final rule contain a federal
mandate that may result in expenditures of $100 million or more for
state, local and tribal governments, in the aggregate, or the private
sector in any one year. Accordingly, the EPA prepared under section 202
of the UMRA a written statement for the final rule. This final rule
also contains a federal mandate that may result in expenditures of $100
million or more for state, local, and tribal governments, in the
aggregate, or the private sector in any one year. The discussion below
has been updated to reflect the changes.
1. Statutory Authority
As discussed in the March 21, 2011, final rule, the statutory
authority for this final rulemaking is section 112 of the CAA. Title
III of the CAA Amendments was enacted to reduce nationwide air toxic
emissions. Section 112(b) of the CAA lists the 188 chemicals,
compounds, or groups of chemicals deemed by Congress to be HAP. These
toxic air pollutants are to be regulated by NESHAP.
Section 112(d) of the CAA directs us to develop NESHAP which
require existing and new major sources to control emissions of HAP
using MACT based standards. This NESHAP applies to all boilers and
process heaters located at major sources of HAP emissions.
2. Social Costs and Benefits
The regulatory impact analysis prepared for the March 21, 2011
final rule, which we have revised for this final rule, including the
agency's assessment of costs and benefits, is detailed in the
``Regulatory Impact Analysis for the Final Industrial Boilers and
Process Heaters MACT (2011)'' and in the ``Regulatory Impact Results
for the Reconsideration Final Rule for National Emission Standards for
Hazardous Air Pollutants for Industrial, Commercial, and Institutional
Boilers and Process Heaters at Major Sources'' in the docket. Based on
estimated compliance costs associated with this final rule and the
predicted change in prices and production in the affected industries,
the estimated social costs of this rule are $1.4 to 1.6 billion (2008
dollars).
It is estimated that 3 years after implementation of this final
rule, HAP would be reduced by 45,000 tpy, including reductions in HCl,
hydrogen fluoride, metallic HAP including mercury, and several other
organic HAP from boilers and process heaters. Studies have determined a
relationship between exposure to these HAP and the onset of cancer,
however, the agency is unable to provide a monetized estimate of the
HAP benefits at this time. In addition, there are significant annual
reductions in fine particulate matter (PM2.5) and in
SO2 that would occur, including 25 thousand tons of
PM2.5 and 558 thousand tons of SO2. These
reductions occur within 3 years after the implementation of the final
regulation and are expected to continue throughout the life of the
affected sources. The major health effect associated with reducing
PM2.5 and PM2.5 precursors (such as
SO2) are a reduction in premature mortality. Other health
effects associated with PM2.5 emission reductions include
avoiding cases of chronic bronchitis, heart attacks, asthma attacks and
work-lost days (i.e., days when employees are unable to work). While we
are unable to monetize the benefits associated with the HAP emissions
reductions, we are able to monetize the benefits associated with the
PM2.5 and SO2 emissions reductions. For
SO2 and PM2.5, we estimated the benefits
associated with health effects of PM but were unable to quantify all
categories of benefits (particularly those associated with ecosystem
and visibility effects). Our estimates of the monetized benefits in
2015 associated with the implementation of the final regulatory action
range from $27 billion (2008 dollars) to $67 billion (2008 dollars)
when using a 3 percent discount rate (or from $25 billion (2008
dollars) to $61 billion (2008 dollars) when using a 7 percent discount
rate). This estimate, at a 3 percent discount rate, is about $25
billion (2008 dollars) to $65 billion (2008 dollars) higher than the
estimated social costs shown earlier in this section. The general
approach used to value benefits is discussed in more detail earlier in
this preamble. For more detailed information on the benefits estimated
for the rulemaking, refer to the RIA and the memos updating the impacts
and benefits in the docket.
3. Future and Disproportionate Costs
The UMRA requires that we estimate, where accurate estimation is
reasonably feasible, future compliance costs imposed by this final rule
and any disproportionate budgetary effects. Our estimates of the future
compliance costs of the rule are discussed previously in this preamble.
We do not believe that there will be any disproportionate budgetary
effects of this final rule on any particular areas of the country,
state or local governments, types of communities (e.g., urban, rural)
or particular industry segments. See the results of the ``Regulatory
Impact Analysis for the Final Industrial Boilers and Process Heaters
MACT (2011).''
4. Effects on the National Economy
The UMRA requires that we estimate the effect of this final rule on
the national economy. To the extent feasible, we must estimate the
effect on productivity, economic growth, full employment, creation of
productive jobs and international competitiveness of the U.S. goods and
services, if we determine that accurate estimates are reasonably
feasible and that such effect is relevant and material.
The nationwide economic impact of this final rule is presented in
the
[[Page 7160]]
``Regulatory Impact Analysis for the Final Industrial Boilers and
Process Heaters MACT (2011)'' and a memoranda that are included in the
docket, entitled ``Regulatory Impact Results for the Reconsideration
Final Rule for National Emission Standards for Hazardous Air Pollutants
for Industrial, Commercial, and Institutional Boilers and Process
Heaters at Major Sources which update the RIA analyses. This analysis
provides estimates of the effect of this rule on some of the categories
mentioned above. The results of the economic impact analysis are
summarized previously in this preamble. The results show that there
will be a small impact on prices and output, and little impact on
communities that may be affected by this final rule. In addition, there
should be little impact on energy markets (in this case, coal, natural
gas, petroleum products and electricity). Hence, the potential impacts
on the categories mentioned above should be small.
5. Consultation With Government Officials
The UMRA requires that we describe the extent of the agency's prior
consultation with affected state, local and tribal officials, summarize
the officials' comments or concerns, and summarize our response to
those comments or concerns. In addition, section 203 of the UMRA
requires that we develop a plan for informing and advising small
governments that may be significantly or uniquely impacted by a final
rule. We consulted with state and local air pollution control officials
during the development of the final rule. We have also held meetings on
this final rule with many of the stakeholders from numerous individual
companies, institutions, environmental groups, consultants and vendors,
labor unions and other interested parties. We have added materials to
the docket to document these meetings.
Consistent with section 205, the EPA has identified and considered
a reasonable number of regulatory alternatives. Additional information
on the costs and environmental impacts of these regulatory alternatives
is presented in the docket.
The regulatory alternative upon which the emission limits in this
final rule are based represents the MACT floors for all subcategories
and, as a result, it is the least costly and least burdensome
alternative.
This rule is not subject to the requirements of section 203 of UMRA
because it contains no regulatory requirements that might significantly
or uniquely affect small governments. While some small governments may
have some sources affected by this final rule, the impacts are not
expected to be significant. Therefore, this final rule is not subject
to the requirements of section 203 of the UMRA.
E. Executive Order 13132: Federalism
This action does not have federalism implications. It will not have
substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government, as
specified in Executive Order 13132. This final rule will not impose
direct compliance costs on state or local governments, and will not
preempt state law. Thus, Executive Order 13132 does not apply to this
action.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have tribal implications, as specified in
Executive Order 13175 (65 FR 67249, November 9, 2000). It will not have
substantial direct effects on tribal governments, on the relationship
between the federal government and Indian tribes, or on the
distribution of power and responsibilities between the federal
government and Indian tribes, as specified in Executive Order 13175.
Thus, Executive Order 13175 does not apply to this action.
G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
The EPA interprets Executive Order 13045 (62 FR 19885, April 23,
1997) as applying to those regulatory actions that concern health or
safety risks, such that the analysis required under section 5-501 of
the Order has the potential to influence the regulation. This action is
not subject to EO 13045 because it is based solely on technology
performance.
H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This action is not a ``significant energy action'' as defined in
Executive Order 13211 (66 FR 28355, May 22, 2001), because it is not
likely to have a significant adverse effect on the supply,
distribution, or use of energy. For the March 21, 2011, final rule, we
estimated a 0.05 percent price increase for the energy sector and a -
0.02 percent percentage change in production. We estimated a 0.09
percent increase in energy imports. For more information on the
estimated energy effects, please refer to the ``Regulatory Impact
Analysis for the Final Industrial Boilers and Process Heaters MACT
(2011).'' The analysis is available in the public docket. While we did
not recreate the RIA for this final action, the energy impacts for
existing sources decreased slightly, and the energy impacts for new
source increased due to the increased number of new sources that is now
projected. Overall, the projected energy use increased slightly but
would not change the analysis that was conducted for the previous final
rule. Therefore, we conclude that this final rule when implemented is
not likely to have a significant adverse effect on the supply,
distribution, or use of energy.
I. National Technology Transfer and Advancement Act
Section 12(d) of the NTTAA, Public Law 104-113, 12(d) (15 U.S.C.
272 note) directs the EPA to use VCS in its regulatory activities
unless to do so would be inconsistent with applicable law or otherwise
impractical. VCS are technical standards (e.g., materials
specifications, test methods, sampling procedures, and business
practices) that are developed or adopted by VCS bodies. NTTAA directs
the EPA to provide Congress, through the OMB, explanations when the
agency decides not to use available and applicable VCS.
This action does not involve any new technical standards from those
contained in the March 21, 2011 final rule. Therefore, the EPA did not
consider the use of any VCS. See 76 FR 15660-15662 for the NTTAA
discussion in the March 21, 2011 final rule.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
Executive Order 12898 (59 FR 7629, February 16, 1994) establishes
federal executive policy on environmental justice. Its main provision
directs federal agencies, to the greatest extent practicable and
permitted by law, to make environmental justice part of their mission
by identifying and addressing, as appropriate, disproportionately high
and adverse human health or environmental effects of their programs,
policies, and activities on minority populations and low-income
populations in the United States.
For the March 2011 final rule, the EPA determined that the rule
would not have disproportionately high and adverse human health or
environmental effects on minority or low-income populations because it
increases the
[[Page 7161]]
level of environmental protection for all affected populations without
having any disproportionately high and adverse human health or
environmental effects on any population, including any minority or low-
income population. Compared to the previous final rule, while the
amendments are somewhat less stringent for some subcategories of units
and more stringent for some others, the overall increased health
benefits demonstrate that the conclusions from the environmental
justice analysis conducted for the previous final rule are still valid.
Therefore, the EPA has determined this final rule will not have
disproportionately high and adverse human or environmental effects on
minority or low-income populations.
K. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this final rule and
other required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. A major rule cannot
take effect until 60 days after it is published in the Federal
Register. This action is a ``major rule'' as defined by 5 U.S.C.
804(2). With the exception of the May 18, 2011 (76 FR 28661), delay of
the effective date revising subpart DDDDD at 76 FR 15451 (March 21,
2011) being lifted January 31, 2013, this rule will be effective April
1, 2013.

10. Section 63.7501 is revised to read as follows:
Sec. 63.7501 Affirmative Defense for Violation of Emission Standards
During Malfunction.
In response to an action to enforce the standards set forth in
Sec. 63.7500 you may assert an affirmative defense to a claim for
civil penalties for violations of such standards that are caused by
malfunction, as defined at Sec. 63.2. Appropriate penalties may be
assessed if you fail to meet your burden of proving all of the
requirements in the affirmative defense. The affirmative defense shall
not be available for claims for injunctive relief.
(a) Assertion of affirmative defense. To establish the affirmative
defense in
[[Page 7164]]
any action to enforce such a standard, you must timely meet the
reporting requirements in paragraph (b) of this section, and must prove
by a preponderance of evidence that:
(1) The violation:
(i) Was caused by a sudden, infrequent, and unavoidable failure of
air pollution control equipment, process equipment, or a process to
operate in a normal or usual manner; and
(ii) Could not have been prevented through careful planning, proper
design, or better operation and maintenance practices; and
(iii) Did not stem from any activity or event that could have been
foreseen and avoided, or planned for; and
(iv) Was not part of a recurring pattern indicative of inadequate
design, operation, or maintenance; and
(2) Repairs were made as expeditiously as possible when a violation
occurred; and
(3) The frequency, amount, and duration of the violation (including
any bypass) were minimized to the maximum extent practicable; and
(4) If the violation resulted from a bypass of control equipment or
a process, then the bypass was unavoidable to prevent loss of life,
personal injury, or severe property damage; and
(5) All possible steps were taken to minimize the impact of the
violation on ambient air quality, the environment, and human health;
and
(6) All emissions monitoring and control systems were kept in
operation if at all possible, consistent with safety and good air
pollution control practices; and
(7) All of the actions in response to the violation were documented
by properly signed, contemporaneous operating logs; and
(8) At all times, the affected source was operated in a manner
consistent with good practices for minimizing emissions; and
(9) A written root cause analysis has been prepared, the purpose of
which is to determine, correct, and eliminate the primary causes of the
malfunction and the violation resulting from the malfunction event at
issue. The analysis shall also specify, using best monitoring methods
and engineering judgment, the amount of any emissions that were the
result of the malfunction.
(b) Report. The owner or operator seeking to assert an affirmative
defense shall submit a written report to the Administrator with all
necessary supporting documentation, that it has met the requirements
set forth in Sec. 63.7500 of this section. This affirmative defense
report shall be included in the first periodic compliance, deviation
report or excess emission report otherwise required after the initial
occurrence of the violation of the relevant standard (which may be the
end of any applicable averaging period). If such compliance, deviation
report or excess emission report is due less than 45 days after the
initial occurrence of the violation, the affirmative defense report may
be included in the second compliance, deviation report or excess
emission report due after the initial occurrence of the violation of
the relevant standard.

b. Revising paragraph (c).
0
c. Revising paragraphs (d) introductory text, (d)(1) introductory text,
and (d)(1)(iii).
Sec. 63.7505 What are my general requirements for complying with this
subpart?
(a) You must be in compliance with the emission limits, work
practice standards, and operating limits in this subpart. These limits
apply to you at all times the affected unit is operating except for the
periods noted in Sec. 63.7500(f).
* * * * *
(c) You must demonstrate compliance with all applicable emission
limits using performance stack testing, fuel analysis, or continuous
monitoring systems (CMS), including a continuous emission monitoring
system (CEMS), continuous opacity monitoring system (COMS), continuous
parameter monitoring system (CPMS), or particulate matter continuous
parameter monitoring system (PM CPMS), where applicable. You may
demonstrate compliance with the applicable emission limit for hydrogen
chloride (HCl), mercury, or total selected metals (TSM) using fuel
analysis if the emission rate calculated according to Sec. 63.7530(c)
is less than the applicable emission limit. (For gaseous fuels, you may
not use fuel analyses to comply with the TSM alternative standard or
the HCl standard.) Otherwise, you must demonstrate compliance for HCl,
mercury, or TSM using performance testing, if subject to an applicable
emission limit listed in Tables 1, 2, or 11 through 13 to this subpart.
(d) If you demonstrate compliance with any applicable emission
limit through performance testing and subsequent compliance with
operating limits (including the use of CPMS), or with a CEMS, or COMS,
you must develop a site-specific monitoring plan according to the
requirements in paragraphs (d)(1) through (4) of this section for the
use of any CEMS, COMS, or CPMS. This requirement also applies to you if
you petition the EPA Administrator for alternative monitoring
parameters under Sec. 63.8(f).
(1) For each CMS required in this section (including CEMS, COMS, or
CPMS), you must develop, and submit to the Administrator for approval
upon request, a site-specific monitoring plan that addresses design,
data collection, and the quality assurance and quality control elements
outlined in Sec. 63.8(d) and the elements described in paragraphs
(d)(1)(i) through (iii) of this section. You must submit this site-
specific monitoring plan, if requested, at least 60 days before your
initial performance evaluation of your CMS. This requirement to develop
and submit a site specific monitoring plan does not apply to affected
sources with existing CEMS or COMS operated according to the
performance specifications under appendix B to part 60 of this chapter
and that meet the requirements of Sec. 63.7525. Using the process
described in Sec. 63.8(f)(4), you may request approval of alternative
monitoring system quality assurance and quality control procedures in
place of those specified in this paragraph and, if approved, include
the alternatives in your site-specific monitoring plan.

subpart, except as specified in paragraphs (a)(2)(i) through (iii) of
this section.
(i) For each boiler or process heater that burns a single type of
fuel, you are not required to conduct a fuel analysis for each type of
fuel burned in your boiler or process heater according to
[[Page 7165]]
Sec. 63.7521 and Table 6 to this subpart. For purposes of this
subpart, units that use a supplemental fuel only for startup, unit
shutdown, and transient flame stability purposes still qualify as units
that burn a single type of fuel, and the supplemental fuel is not
subject to the fuel analysis requirements under Sec. 63.7521 and Table
6 to this subpart.
(ii) When natural gas, refinery gas, or other gas 1 fuels are co-
fired with other fuels, you are not required to conduct a fuel analysis
of those fuels according to Sec. 63.7521 and Table 6 to this subpart.
If gaseous fuels other than natural gas, refinery gas, or other gas 1
fuels are co-fired with other fuels and those gaseous fuels are subject
to another subpart of this part, part 60, part 61, or part 65, you are
not required to conduct a fuel analysis of those fuels according to
Sec. 63.7521 and Table 6 to this subpart.
(iii) You are not required to conduct a chlorine fuel analysis for
any gaseous fuels. You must conduct a fuel analysis for mercury on
gaseous fuels unless the fuel is exempted in paragraphs (a)(2)(i) and
(ii) of this section.
(3) Establish operating limits according to Sec. 63.7530 and Table
7 to this subpart.
(4) Conduct CMS performance evaluations according to Sec. 63.7525.
(b) For each boiler or process heater that you elect to demonstrate
compliance with the applicable emission limits in Tables 1 or 2 or 11
through 13 to this subpart for HCl, mercury, or TSM through fuel
analysis, your initial compliance requirement is to conduct a fuel
analysis for each type of fuel burned in your boiler or process heater
according to Sec. 63.7521 and Table 6 to this subpart and establish
operating limits according to Sec. 63.7530 and Table 8 to this
subpart. The fuels described in paragraph (a)(2)(i) and (ii) of this
section are exempt from these fuel analysis and operating limit
requirements. The fuels described in paragraph (a)(2)(ii) of this
section are exempt from the chloride fuel analysis and operating limit
requirements. Boilers and process heaters that use a CEMS for mercury
or HCl are exempt from the performance testing and operating limit
requirements specified in paragraph (a) of this section for the HAP for
which CEMS are used.
(c) If your boiler or process heater is subject to a carbon
monoxide (CO) limit, your initial compliance demonstration for CO is to
conduct a performance test for CO according to Table 5 to this subpart
or conduct a performance evaluation of your continuous CO monitor, if
applicable, according to Sec. 63.7525(a). Boilers and process heaters
that use a CO CEMS to comply with the applicable alternative CO CEMS
emission standard listed in Tables 12, or 11 through 13 to this
subpart, as specified in Sec. 63.7525(a), are exempt from the initial
CO performance testing and oxygen concentration operating limit
requirements specified in paragraph (a) of this section.
(d) If your boiler or process heater is subject to a PM limit, your
initial compliance demonstration for PM is to conduct a performance
test in accordance with Sec. 63.7520 and Table 5 to this subpart.
(e) For existing affected sources (as defined in Sec. 63.7490),
you must complete the initial compliance demonstration, as specified in
paragraphs (a) through (d) of this section, no later than 180 days
after the compliance date that is specified for your source in Sec.
63.7495 and according to the applicable provisions in Sec. 63.7(a)(2)
as cited in Table 10 to this subpart, except as specified in paragraph
(j) of this section. You must complete an initial tune-up by following
the procedures described in Sec. 63.7540(a)(10)(i) through (vi) no
later than the compliance date specified in Sec. 63.7495, except as
specified in paragraph (j) of this section. You must complete the one-
time energy assessment specified in Table 3 to this subpart no later
than the compliance date specified in Sec. 63.7495, except as
specified in paragraph (j) of this section.
(f) For new or reconstructed affected sources (as defined in Sec.
63.7490), you must complete the initial compliance demonstration with
the emission limits no later than July 30, 2013 or within 180 days
after startup of the source, whichever is later. If you are
demonstrating compliance with an emission limit in Tables 11 through 13

applicable emission limit in Table 1 to this subpart, you must
demonstrate compliance with the applicable emission limit in Table 1 no
later than July 29, 2016.
(g) For new or reconstructed affected sources (as defined in Sec.
63.7490), you must demonstrate initial compliance with the applicable
work practice standards in Table 3 to this subpart within the
applicable annual, biennial, or 5-year schedule as specified in Sec.
63.7540(a) following the initial compliance date specified in Sec.

13. Section 63.7515 is revised to read as follows:
Sec. 63.7515 When must I conduct subsequent performance tests, fuel
analyses, or tune-ups?
(a) You must conduct all applicable performance tests according to
Sec. 63.7520 on an annual basis, except as specified in paragraphs (b)
through (e), (g), and (h) of this section. Annual performance tests
must be completed no more than 13 months after the previous performance
test, except as specified in paragraphs (b) through (e), (g), and (h)
of this section.
(b) If your performance tests for a given pollutant for at least 2
consecutive years show that your emissions are at or below 75 percent
of the emission limit (or, in limited instances as specified in Tables
1 and 2 or 11 through 13 to this subpart, at or below the emission
limit) for the pollutant, and if there are no changes in the operation
of the individual boiler or process heater or air pollution control
equipment that could increase emissions, you may choose to conduct
performance tests for the pollutant every third year. Each such
performance test must be conducted no more than 37 months after the
previous performance test. If you elect to
[[Page 7166]]
demonstrate compliance using emission averaging under Sec. 63.7522,
you must continue to conduct performance tests annually. The
requirement to test at maximum chloride input level is waived unless
the stack test is conducted for HCl. The requirement to test at maximum
mercury input level is waived unless the stack test is conducted for
mercury. The requirement to test at maximum TSM input level is waived
unless the stack test is conducted for TSM.
(c) If a performance test shows emissions exceeded the emission
limit or 75 percent of the emission limit (as specified in Tables 1 and
2 or 11 through 13 to this subpart) for a pollutant, you must conduct
annual performance tests for that pollutant until all performance tests
over a consecutive 2-year period meet the required level (at or below
75 percent of the emission limit, as specified in Tables 1 and 2 or 11
through 13 to this subpart).
(d) If you are required to meet an applicable tune-up work practice
standard, you must conduct an annual, biennial, or 5-year performance
tune-up according to Sec. 63.7540(a)(10), (11), or (12), respectively.
Each annual tune-up specified in Sec. 63.7540(a)(10) must be no more
than 13 months after the previous tune-up. Each biennial tune-up
specified in Sec. 63.7540(a)(11) must be conducted no more than 25
months after the previous tune-up. Each 5-year tune-up specified in
Sec. 63.7540(a)(12) must be conducted no more than 61 months after the
previous tune-up. For a new or reconstructed affected source (as
defined in Sec. 63.7490), the first annual, biennial, or 5-year tune-
up must be no later than 13 months, 25 months, or 61 months,
respectively, after the initial startup of the new or reconstructed
affected source.
(e) If you demonstrate compliance with the mercury, HCl, or TSM
based on fuel analysis, you must conduct a monthly fuel analysis
according to Sec. 63.7521 for each type of fuel burned that is subject
to an emission limit in Tables 1, 2, or 11 through 13 to this subpart.
You may comply with this monthly requirement by completing the fuel
analysis any time within the calendar month as long as the analysis is
separated from the previous analysis by at least 14 calendar days. If
you burn a new type of fuel, you must conduct a fuel analysis before
burning the new type of fuel in your boiler or process heater. You must
still meet all applicable continuous compliance requirements in Sec.
63.7540. If each of 12 consecutive monthly fuel analyses demonstrates
75 percent or less of the compliance level, you may decrease the fuel
analysis frequency to quarterly for that fuel. If any quarterly sample
exceeds 75 percent of the compliance level or you begin burning a new
type of fuel, you must return to monthly monitoring for that fuel,
until 12 months of fuel analyses are again less than 75 percent of the
compliance level.
(f) You must report the results of performance tests and the
associated fuel analyses within 60 days after the completion of the
performance tests. This report must also verify that the operating
limits for each boiler or process heater have not changed or provide
documentation of revised operating limits established according to
Sec. 63.7530 and Table 7 to this subpart, as applicable. The reports
for all subsequent performance tests must include all applicable
information required in Sec. 63.7550.
(g) For affected sources (as defined in Sec. 63.7490) that have
not operated since the previous compliance demonstration and more than
one year has passed since the previous compliance demonstration, you
must complete the subsequent compliance demonstration, if subject to
the emission limits in Tables 1, 2, or 11 through 13 to this subpart,
no later than 180 days after the re-start of the affected source and
according to the applicable provisions in Sec. 63.7(a)(2) as cited in
Table 10 to this subpart. You must complete a subsequent tune-up by
following the procedures described in Sec. 63.7540(a)(10)(i) through
(vi) and the schedule described in Sec. 63.7540(a)(13) for units that
are not operating at the time of their scheduled tune-up.
(h) If your affected boiler or process heater is in the unit
designed to burn light liquid subcategory and you combust ultra low
sulfur liquid fuel, you do not need to conduct further performance
tests if the pollutants measured during the initial compliance
performance tests meet the emission limits in Tables 1 or 2 of this
subpart providing you demonstrate ongoing compliance with the emissions
limits by monitoring and recording the type of fuel combusted on a
monthly basis. If you intend to use a fuel other than ultra low sulfur
liquid fuel, natural gas, refinery gas, or other gas 1 fuel, you must
conduct new performance tests within 60 days of burning the new fuel
type.
(i) If you operate a CO CEMS that meets the Performance
Specifications outlined in Sec. 63.7525(a)(3) of this subpart to
demonstrate compliance with the applicable alternative CO CEMS emission
standard listed in Tables 1, 2, or 11 through 13 to this subpart, you
are not required to conduct CO performance tests and are not subject to
the oxygen concentration operating limit requirement specified in Sec.
63.7510(a).

14. Section Sec. 63.7520 is amended by revising paragraphs (a), (c),
(d), and (e) and adding paragraph (f) to read as follows:
Sec. 63.7520 What stack tests and procedures must I use?
(a) You must conduct all performance tests according to Sec.
63.7(c), (d), (f), and (h). You must also develop a site-specific stack
test plan according to the requirements in Sec. 63.7(c). You shall
conduct all performance tests under such conditions as the
Administrator specifies to you based on the representative performance
of each boiler or process heater for the period being tested. Upon
request, you shall make available to the Administrator such records as
may be necessary to determine the conditions of the performance tests.
* * * * *
(c) You must conduct each performance test under the specific
conditions listed in Tables 5 and 7 to this subpart. You must conduct
performance tests at representative operating load conditions while
burning the type of fuel or mixture of fuels that has the highest
content of chlorine and mercury, and TSM if you are opting to comply
with the TSM alternative standard and you must demonstrate initial
compliance and establish your operating limits based on these
performance tests. These requirements could result in the need to
conduct more than one performance test. Following each performance test
and until the next performance test, you must comply with the operating
limit for operating load conditions specified in Table 4 to this
subpart.
(d) You must conduct a minimum of three separate test runs for each
performance test required in this section, as specified in Sec.
63.7(e)(3). Each test run must comply with the minimum applicable
sampling times or volumes specified in Tables 1 and 2 or 11 through 13
to this subpart.
(e) To determine compliance with the emission limits, you must use
the F-Factor methodology and equations in sections 12.2 and 12.3 of EPA
Method 19 at 40 CFR part 60, appendix A-7 of this chapter to convert
the measured particulate matter (PM) concentrations, the measured HCl
concentrations, the measured mercury concentrations, and the measured
TSM concentrations that result from the performance test to pounds per
million Btu heat input emission rates.
[[Page 7167]]
(f) Except for a 30-day rolling average based on CEMS (or sorbent
trap monitoring system) data, if measurement results for any pollutant
are reported as below the method detection level (e.g., laboratory
analytical results for one or more sample components are below the
method defined analytical detection level), you must use the method
detection level as the measured emissions level for that pollutant in
calculating compliance. The measured result for a multiple component
analysis (e.g., analytical values for multiple Method 29 fractions both
for individual HAP metals and for total HAP metals) may include a
combination of method detection level data and analytical data reported
above the method detection level.

Sec. 63.7530 How do I demonstrate initial compliance with the
emission limitations, fuel specifications and work practice standards?
(a) You must demonstrate initial compliance with each emission
limit that applies to you by conducting initial performance tests and
fuel analyses and establishing operating limits, as applicable,
according to Sec. 63.7520, paragraphs (b) and (c) of this section, and
Tables 5 and 7 to this subpart. The requirement to conduct a fuel
analysis is not applicable for units that burn a single type of fuel,
as specified by Sec. 63.7510(a)(2)(i). If applicable, you must also
install, operate, and maintain all applicable CMS (including CEMS,
COMS, and CPMS) according to Sec. 63.7525.
(b) If you demonstrate compliance through performance testing, you
must establish each site-specific operating limit in Table 4 to this
subpart that applies to you according to the requirements in Sec.
63.7520, Table 7 to this subpart, and paragraph (b)(4) of this section,
as applicable. You must also conduct fuel analyses according to Sec.
63.7521 and establish maximum fuel pollutant input levels according to
paragraphs (b)(1) through (3) of this section, as applicable, and as
specified in Sec. 63.7510(a)(2). (Note that Sec. 63.7510(a)(2)
exempts certain fuels from the fuel analysis requirements.) However, if
you switch fuel(s) and cannot show that the new fuel(s) does (do) not
increase the chlorine, mercury, or TSM input into the unit through the
results of fuel analysis, then you must repeat the performance test to
demonstrate compliance while burning the new fuel(s).
* * * * *
(3) If you opt to comply with the alternative TSM limit, you must
establish the maximum TSM fuel input (TSMinput) for solid or liquid
fuels during the initial fuel analysis according to the procedures in
paragraphs (b)(3)(i) through (iii) of this section.
(i) You must determine the fuel type or fuel mixture that you could
burn in your boiler or process heater that has the highest content of
TSM.
(ii) During the fuel analysis for TSM, you must determine the
fraction of the total heat input for each fuel type burned (Qi) based
on the fuel mixture that has the highest content of TSM, and the
average TSM concentration of each fuel type burned (TSMi).
(iii) You must establish a maximum TSM input level using Equation 9
of this section.
[GRAPHIC] [TIFF OMITTED] TR31JA13.013
Where:
TSMinput = Maximum amount of TSM entering the boiler or process
heater through fuels burned in units of pounds per million Btu.
TSMi = Arithmetic average concentration of TSM in fuel type, i,
analyzed according to Sec. 63.7521, in units of pounds per million
Btu.
Qi = Fraction of total heat input from fuel type, i, based on the
fuel mixture that has the highest content of TSM. If you do not burn
multiple fuel types during the performance testing, it is not
necessary to determine the value of this term. Insert a value of
``1'' for Qi.
n = Number of different fuel types burned in your boiler or process
heater for the mixture that has the highest content of TSM.
(4) You must establish parameter operating limits according to
paragraphs (b)(4)(i) through (ix) of this section. As indicated in
Table 4 to this subpart, you are not required to establish and comply
with the operating parameter limits when you are using a CEMS to
monitor and demonstrate compliance with the applicable emission limit
for that control device parameter.
(i) For a wet acid gas scrubber, you must establish the minimum
scrubber effluent pH and liquid flow rate as defined in Sec. 63.7575,
as your operating limits during the performance test during which you
demonstrate compliance with your applicable limit. If you use a wet
scrubber and you conduct separate performance tests for HCl and mercury
emissions, you must establish one set of minimum scrubber effluent pH,
liquid flow rate, and
[[Page 7175]]
pressure drop operating limits. The minimum scrubber effluent pH
operating limit must be established during the HCl performance test. If
you conduct multiple performance tests, you must set the minimum liquid
flow rate operating limit at the higher of the minimum values
established during the performance tests.
(ii) For any particulate control device (e.g., ESP, particulate wet
scrubber, fabric filter) for which you use a PM CPMS, you must
establish your PM CPMS operating limit and determine compliance with it
according to paragraphs (b)(4)(ii)(A) through (F) of this section.
(A) Determine your operating limit as the average PM CPMS output
value recorded during the most recent performance test run
demonstrating compliance with the filterable PM emission limit or at
the PM CPMS output value corresponding to 75 percent of the emission
limit if your PM performance test demonstrates compliance below 75
percent of the emission limit. You must verify an existing or establish
a new operating limit after each repeated performance test. You must
repeat the performance test annually and reassess and adjust the site-
specific operating limit in accordance with the results of the
performance test.
(1) Your PM CPMS must provide a 4-20 milliamp output and the
establishment of its relationship to manual reference method
measurements must be determined in units of milliamps.
(2) Your PM CPMS operating range must be capable of reading PM
concentrations from zero to a level equivalent to at least two times
your allowable emission limit. If your PM CPMS is an auto-ranging
instrument capable of multiple scales, the primary range of the
instrument must be capable of reading PM concentration from zero to a
level equivalent to two times your allowable emission limit.
(3) During the initial performance test or any such subsequent
performance test that demonstrates compliance with the PM limit, record
and average all milliamp output values from the PM CPMS for the periods
corresponding to the compliance test runs (e.g., average all your PM
CPMS output values for three corresponding 2-hour Method 5I test runs).
(B) If the average of your three PM performance test runs are below
75 percent of your PM emission limit, you must calculate an operating
limit by establishing a relationship of PM CPMS signal to PM
concentration using the PM CPMS instrument zero, the average PM CPMS
values corresponding to the three compliance test runs, and the average
PM concentration from the Method 5 or performance test with the
procedures in paragraphs (b)(4)(ii)(B)(1) through (4) of this section.
(1) Determine your instrument zero output with one of the following
procedures:
(i) Zero point data for in-situ instruments should be obtained by
removing the instrument from the stack and monitoring ambient air on a
test bench.
(ii) Zero point data for extractive instruments should be obtained
by removing the extractive probe from the stack and drawing in clean
ambient air.
(iii) The zero point may also be established by performing manual
reference method measurements when the flue gas is free of PM emissions
or contains very low PM concentrations (e.g., when your process is not
operating, but the fans are operating or your source is combusting only
natural gas) and plotting these with the compliance data to find the
zero intercept.
(iv) If none of the steps in paragraphs (b)(4)(ii)(B)(1)(i) through
(iii) of this section are possible, you must use a zero output value
provided by the manufacturer.
(2) Determine your PM CPMS instrument average in milliamps, and the
average of your corresponding three PM compliance test runs, using
equation 10.
[GRAPHIC] [TIFF OMITTED] TR31JA13.014
Where:
X1 = the PM CPMS data points for the three runs
constituting the performance test,
Y1 = the PM concentration value for the three runs
constituting the performance test, and
n = the number of data points.
(3) With your instrument zero expressed in milliamps, your three
run average PM CPMS milliamp value, and your three run average PM
concentration from your three compliance tests, determine a
relationship of lb/MMBtu per milliamp with equation 11.
[GRAPHIC] [TIFF OMITTED] TR31JA13.015
Where:
R = the relative lb/MMBtu per milliamp for your PM CPMS,
Y1 = the three run average lb/MMBtu PM concentration,
X1 = the three run average milliamp output from you PM
CPMS, and
z = the milliamp equivalent of your instrument zero determined from
(B)(i).
(4) Determine your source specific 30-day rolling average operating
limit using the lb/MMBtu per milliamp value from Equation 11 in
equation 12, below. This sets your operating limit at the PM CPMS
output value corresponding to 75 percent of your emission limit.
[GRAPHIC] [TIFF OMITTED] TR31JA13.016
Where:
Ol = the operating limit for your PM CPMS on a 30-day
rolling average, in milliamps.
L = your source emission limit expressed in lb/MMBtu,
z = your instrument zero in milliamps, determined from (B)(i), and
R = the relative lb/MMBtu per milliamp for your PM CPMS, from
Equation 11.
(C) If the average of your three PM compliance test runs is at or
above 75 percent of your PM emission limit you must determine your 30-
day rolling average operating limit by averaging the PM CPMS milliamp
output corresponding to your three PM performance test runs that
demonstrate compliance with the emission limit using equation 13 and
you must submit all compliance test and PM CPMS data according to the
reporting requirements in paragraph (b)(4)(ii)(F) of this section.
[GRAPHIC] [TIFF OMITTED] TR31JA13.017
Where:
X1 = the PM CPMS data points for all runs i,
n = the number of data points, and
Oh = your site specific operating limit, in milliamps.
(D) To determine continuous compliance, you must record the PM
[[Page 7176]]
CPMS output data for all periods when the process is operating and the
PM CPMS is not out-of-control. You must demonstrate continuous
compliance by using all quality-assured hourly average data collected
by the PM CPMS for all operating hours to calculate the arithmetic
average operating parameter in units of the operating limit (milliamps)
on a 30-day rolling average basis, updated at the end of each new
operating hour. Use Equation 14 to determine the 30-day rolling
average.
[GRAPHIC] [TIFF OMITTED] TR31JA13.018
Where:
30-day = 30-day average.
Hpvi = is the hourly parameter value for hour i
n = is the number of valid hourly parameter values collected over
the previous 720 operating hours.
(E) Use EPA Method 5 of appendix A to part 60 of this chapter to
determine PM emissions. For each performance test, conduct three
separate runs under the conditions that exist when the affected source
is operating at the highest load or capacity level reasonably expected
to occur. Conduct each test run to collect a minimum sample volume
specified in Tables 1, 2, or 11 through 13 to this subpart, as
applicable, for determining compliance with a new source limit or an
existing source limit. Calculate the average of the results from three
runs to determine compliance. You need not determine the PM collected
in the impingers (``back half'') of the Method 5 particulate sampling
train to demonstrate compliance with the PM standards of this subpart.
This shall not preclude the permitting authority from requiring a
determination of the ``back half'' for other purposes.
(F) For PM performance test reports used to set a PM CPMS operating
limit, the electronic submission of the test report must also include
the make and model of the PM CPMS instrument, serial number of the
instrument, analytical principle of the instrument (e.g. beta
attenuation), span of the instruments primary analytical range,
milliamp value equivalent to the instrument zero output, technique by
which this zero value was determined, and the average milliamp signals
corresponding to each PM compliance test run. (iii) For a particulate
wet scrubber, you must establish the minimum pressure drop and liquid
flow rate as defined in Sec. 63.7575, as your operating limits during
the three-run performance test during which you demonstrate compliance
with your applicable limit. If you use a wet scrubber and you conduct
separate performance tests for PM and TSM emissions, you must establish
one set of minimum scrubber liquid flow rate and pressure drop
operating limits. The minimum scrubber effluent pH operating limit must
be established during the HCl performance test. If you conduct multiple
performance tests, you must set the minimum liquid flow rate and
pressure drop operating limits at the higher of the minimum values
established during the performance tests.
(iii) For an electrostatic precipitator (ESP) operated with a wet
scrubber, you must establish the minimum total secondary electric power
input, as defined in Sec. 63.7575, as your operating limit during the
three-run performance test during which you demonstrate compliance with
your applicable limit. (These operating limits do not apply to ESP that
are operated as dry controls without a wet scrubber.)
(iv) For a dry scrubber, you must establish the minimum sorbent
injection rate for each sorbent, as defined in Sec. 63.7575, as your
operating limit during the three-run performance test during which you
demonstrate compliance with your applicable limit.
(v) For activated carbon injection, you must establish the minimum
activated carbon injection rate, as defined in Sec. 63.7575, as your
operating limit during the three-run performance test during which you
demonstrate compliance with your applicable limit.
(vi) The operating limit for boilers or process heaters with fabric
filters that demonstrate continuous compliance through bag leak
detection systems is that a bag leak detection system be installed
according to the requirements in Sec. 63.7525, and that each fabric
filter must be operated such that the bag leak detection system alert
is not activated more than 5 percent of the operating time during a 6-
month period.
(vii) For a minimum oxygen level, if you conduct multiple
performance tests, you must set the minimum oxygen level at the lower
of the minimum values established during the performance tests.
(viii) The operating limit for boilers or process heaters that
demonstrate continuous compliance with the HCl emission limit using a
SO2 CEMS is to install and operate the SO2
according to the requirements in Sec. 63.7525(m) establish a maximum
SO2 emission rate equal to the highest hourly average
SO2 measurement during the most recent three-run performance
test for HCl.
(c) If you elect to demonstrate compliance with an applicable
emission limit through fuel analysis, you must conduct fuel analyses
according to Sec. 63.7521 and follow the procedures in paragraphs
(c)(1) through (5) of this section.
* * * * *
(2) You must determine the 90th percentile confidence level fuel
pollutant concentration of the composite samples analyzed for each fuel
type using the one-sided t-statistic test described in Equation 15 of
this section.
[GRAPHIC] [TIFF OMITTED] TR31JA13.019
Where:
P90 = 90th percentile confidence level pollutant concentration, in
pounds per million Btu.
Mean = Arithmetic average of the fuel pollutant concentration in the
fuel samples analyzed according to Sec. 63.7521, in units of pounds
per million Btu.
SD = Standard deviation of the mean of pollutant concentration in
the fuel samples analyzed according to Sec. 63.7521, in units of
pounds per million Btu. SD is calculated as the sample standard
[[Page 7177]]
deviation divided by the square root of the number of samples.
t = t distribution critical value for 90th percentile
(t0.1) probability for the appropriate degrees of freedom
(number of samples minus one) as obtained from a t-Distribution
Critical Value Table.
(3) To demonstrate compliance with the applicable emission limit
for HCl, the HCl emission rate that you calculate for your boiler or
process heater using Equation 16 of this section must not exceed the
applicable emission limit for HCl.
[GRAPHIC] [TIFF OMITTED] TR31JA13.020
Where:
HCl = HCl emission rate from the boiler or process heater in units
of pounds per million Btu.
Ci90 = 90th percentile confidence level concentration of chlorine in
fuel type, i, in units of pounds per million Btu as calculated
according to Equation 11 of this section.
Qi = Fraction of total heat input from fuel type, i, based on the
fuel mixture that has the highest content of chlorine. If you do not
burn multiple fuel types, it is not necessary to determine the value
of this term. Insert a value of ``1'' for Qi.
n = Number of different fuel types burned in your boiler or process
heater for the mixture that has the highest content of chlorine.
1.028 = Molecular weight ratio of HCl to chlorine.

for TSM for solid or liquid fuels, the TSM emission rate that you
calculate for your boiler or process heater from solid fuels using
Equation 18 of this section must not exceed the applicable emission
limit for TSM.

signed certification that the energy assessment was completed according
to Table 3 to this subpart and is an accurate depiction of your
facility at the time of the assessment.
* * * * *
(g) If you elect to demonstrate that a gaseous fuel meets the
specifications of another gas 1 fuel as defined in Sec. 63.7575, you
must conduct an initial fuel specification analyses according to Sec.

63.7540(c) and maintain records of the results of the testing as
outlined in Sec. 63.7555(g). For samples where the initial mercury
specification has not been exceeded, you will include a signed

initial fuel specification test meets the gas specification outlined in
the definition of other gas 1 fuels.
(h) If you own or operate a unit subject to emission limits in
Tables 1 or 2 or 11 through 13 to this subpart, you must meet the work
practice standard according to Table 3 of this subpart. During startup
and shutdown, you must only follow the work practice standards
according to item 5 of Table 3 of this subpart.
(i) If you opt to comply with the alternative SO2 CEMS
operating limit in Tables 4 and 8 to this subpart, you may do so only
if your affected boiler or process heater:

The revisions and addition read as follows:
Sec. 63.7533 Can I use efficiency credits earned from implementation
of energy conservation measures to comply with this subpart?
(a) If you elect to comply with the alternative equivalent output-
based emission limits, instead of the heat input-based limits listed in
Table 2 to this subpart, and you want to take credit for implementing
energy conservation measures identified in an energy assessment, you
may demonstrate compliance using efficiency credits according to the
procedures in this section. You may use this compliance approach for an
existing affected boiler for demonstrating initial compliance according
to Sec. 63.7522(e) and for demonstrating monthly compliance according
to Sec. 63.7522(f). Owners or operators using this compliance approach
must establish an emissions benchmark, calculate and document the
efficiency credits, develop an Implementation Plan, comply with the
general reporting requirements, and apply the efficiency credit
according to the procedures in paragraphs (b) through (f) of this
section. You cannot use this compliance approach for a new or
reconstructed affected boiler. Additional guidance from the Department
of Energy on efficiency credits is available at: http://www.epa.gov/ttn/atw/boiler/boilerpg.html.
(b) * * *
(1) The benchmark from which efficiency credits may be generated
shall be determined by using the most representative, accurate, and
reliable process available for the source. The benchmark shall be
established for a one-year period before the date that an energy demand
reduction occurs, unless it can be demonstrated that a different time
period is more representative of historical operations.
* * * * *
(4) Collect non-energy related facility and operational data to
normalize, if necessary, the benchmark to current operations, such as
building size, operating hours, etc. If possible, use actual data that
are current and timely rather than estimated data.
(c) Efficiency credits can be generated if the energy conservation
measures were implemented after January 1, 2008 and if sufficient
information is available to determine the appropriate value of credits.
(1) The following emission points cannot be used to generate
efficiency credits:
(i) Energy conservation measures implemented on or before January
1, 2008, unless the level of energy demand reduction is increased after
January 1, 2008, in which case credit will be allowed only for change
in demand reduction achieved after January 1, 2008.
(ii) Efficiency credits on shut-down boilers. Boilers that are shut
down cannot be used to generate credits unless the facility provides
documentation linking the permanent shutdown to energy conservation
measures identified in the energy assessment. In this case, the bench
established for the affected boiler to which the credits from the
shutdown will be applied must be revised to include the benchmark
established for the shutdown boiler.
(2) * * *
(i) Calculate annual credits for all energy demand points. Use
Equation 19 to calculate credits. Energy conservation measures that
meet the criteria of paragraph (c)(1) of this section shall not be
included, except as specified in paragraph (c)(1)(i) of this section.
* * * * *
(3) Credits are generated by the difference between the benchmark
that is established for each affected boiler, and the actual energy
demand reductions from energy conservation measures implemented after
January 1, 2008. Credits shall be calculated using Equation 19 of this
section as follows:
(i) The overall equation for calculating credits is:
[GRAPHIC] [TIFF OMITTED] TR31JA13.023
Where:
ECredits = Energy Input Savings for all energy conservation measures
implemented for an affected boiler, expressed as a decimal fraction
of the baseline energy input.
EISiactual = Energy Input Savings for each energy
conservation measure, i, implemented for an affected boiler, million
Btu per year.
EIbaseline = Energy Input baseline for the affected
boiler, million Btu per year.
n = Number of energy conservation measures included in the
efficiency credit for the affected boiler.
(ii) [Reserved]
(d) The owner or operator shall develop, and submit for approval
upon request by the Administrator, an Implementation Plan containing
all of the information required in this paragraph for all boilers to be
included in an efficiency credit approach. The Implementation Plan
shall identify all existing affected boilers to be included in applying
the efficiency credits. The Implementation Plan shall include a
description of the energy conservation measures implemented and the
energy savings generated from each measure and an explanation of the
criteria used for determining that savings. If requested, you must
submit the implementation plan for efficiency credits to the
Administrator for review and approval no later than 180 days before the
date on which the facility intends to demonstrate compliance using the
efficiency credit approach.
(e) The emissions rate as calculated using Equation 20 of this
section from each existing boiler participating in the efficiency
credit option must be in compliance with the limits in Table 2 to this
subpart at all times the affected unit is operating, following the
compliance date specified in Sec. 63.7495.
(f) You must use Equation 20 of this section to demonstrate initial
compliance by demonstrating that the emissions from the affected boiler
participating in the efficiency credit compliance approach do not
exceed the emission limits in Table 2 to this subpart.
[[Page 7179]]
[GRAPHIC] [TIFF OMITTED] TR31JA13.024
Where:
Eadj = Emission level adjusted by applying the efficiency
credits earned, lb per million Btu steam output (or lb per MWh) for
the affected boiler.
Em = Emissions measured during the performance test, lb
per million Btu steam output (or lb per MWh) for the affected
boiler.
ECredits = Efficiency credits from Equation 19 for the affected
boiler.
(g) As part of each compliance report submitted as required under
Sec. 63.7550, you must include documentation that the energy
conservation measures implemented continue to generate the credit for
use in demonstrating compliance with the emission limits.

20. Section 63.7535 is amended by revising the section heading and
paragraphs (b), (c), and (d) to read as follows:
Sec. 63.7535 Is there a minimum amount of monitoring data I must
obtain?
* * * * *
(b) You must operate the monitoring system and collect data at all
required intervals at all times that each boiler or process heater is
operating and compliance is required, except for periods of monitoring
system malfunctions or out of control periods (see Sec. 63.8(c)(7) of
this part), and required monitoring system quality assurance or control
activities, including, as applicable, calibration checks, required zero
and span adjustments, and scheduled CMS maintenance as defined in your
site-specific monitoring plan. A monitoring system malfunction is any
sudden, infrequent, not reasonably preventable failure of the
monitoring system to provide valid data. Monitoring system failures
that are caused in part by poor maintenance or careless operation are
not malfunctions. You are required to complete monitoring system
repairs in response to monitoring system malfunctions or out-of-control
periods and to return the monitoring system to operation as
expeditiously as practicable.
(c) You may not use data recorded during monitoring system
malfunctions or out-of-control periods, repairs associated with
monitoring system malfunctions or out-of-control periods, or required
monitoring system quality assurance or control activities in data
averages and calculations used to report emissions or operating levels.
You must record and make available upon request results of CMS
performance audits and dates and duration of periods when the CMS is
out of control to completion of the corrective actions necessary to
return the CMS to operation consistent with your site-specific
monitoring plan. You must use all the data collected during all other
periods in assessing compliance and the operation of the control device
and associated control system.
(d) Except for periods of monitoring system malfunctions, repairs
associated with monitoring system malfunctions, and required monitoring
system quality assurance or quality control activities (including, as
applicable, system accuracy audits, calibration checks, and required
zero and span adjustments), failure to collect required data is a
deviation of the monitoring requirements. In calculating monitoring
results, do not use any data collected during periods when the
monitoring system is out of control as specified in your site-specific
monitoring plan, while conducting repairs associated with periods when
the monitoring system is out of control, or while conducting required
monitoring system quality assurance or quality control activities. You
must calculate monitoring results using all other monitoring data
collected while the process is operating. You must report all periods
when the monitoring system is out of control in your annual report.

21. Section 63.7540 is revised to read as follows:
Sec. 63.7540 How do I demonstrate continuous compliance with the
emission limitations, fuel specifications and work practice standards?
(a) You must demonstrate continuous compliance with each emission
limit in Tables 1 and 2 or 11 through 13 to this subpart, the work
practice standards in Table 3 to this subpart, and the operating limits
in Table 4 to this subpart that applies to you according to the methods
specified in Table 8 to this subpart and paragraphs (a)(1) through (19)
of this section.
(1) Following the date on which the initial compliance
demonstration is completed or is required to be completed under
Sec. Sec. 63.7 and 63.7510, whichever date comes first, operation
above the established maximum or below the established minimum
operating limits shall constitute a deviation of established operating
limits listed in Table 4 of this subpart except during performance
tests conducted to determine compliance with the emission limits or to
establish new operating limits. Operating limits must be confirmed or
reestablished during performance tests.
(2) As specified in Sec. 63.7550(c), you must keep records of the
type and amount of all fuels burned in each boiler or process heater
during the reporting period to demonstrate that all fuel types and
mixtures of fuels burned would result in either of the following:
(i) Lower emissions of HCl, mercury, and TSM than the applicable
emission limit for each pollutant, if you demonstrate compliance
through fuel analysis.
(ii) Lower fuel input of chlorine, mercury, and TSM than the
maximum values calculated during the last performance test, if you
demonstrate compliance through performance testing.
(3) If you demonstrate compliance with an applicable HCl emission
limit through fuel analysis for a solid or liquid fuel and you plan to
burn a new type of solid or liquid fuel, you must recalculate the HCl
emission rate using Equation 12 of Sec. 63.7530 according to
paragraphs (a)(3)(i) through (iii) of this section. You are not
required to conduct fuel analyses for the fuels described in Sec.
63.7510(a)(2)(i) through (iii). You may exclude the fuels described in
Sec. 63.7510(a)(2)(i) through (iii) when recalculating the HCl
emission rate.
(i) You must determine the chlorine concentration for any new fuel
type in units of pounds per million Btu, based on supplier data or your
own fuel analysis, according to the provisions in your site-specific
fuel analysis plan developed according to Sec. 63.7521(b).
(ii) You must determine the new mixture of fuels that will have the
highest content of chlorine.
(iii) Recalculate the HCl emission rate from your boiler or process
heater under these new conditions using Equation 12 of Sec. 63.7530.
The recalculated HCl emission rate must be less than the applicable
emission limit.
(4) If you demonstrate compliance with an applicable HCl emission
limit through performance testing and you plan to burn a new type of
fuel or a new mixture of fuels, you must recalculate the maximum
chlorine input using Equation 7 of Sec. 63.7530. If the results of
recalculating the maximum chlorine input using Equation 7 of Sec.
63.7530 are greater than the maximum chlorine input level established
during the previous performance test, then you must conduct a new
performance test within 60 days of burning the new fuel type or fuel
mixture according to the
[[Page 7180]]
procedures in Sec. 63.7520 to demonstrate that the HCl emissions do
not exceed the emission limit. You must also establish new operating
limits based on this performance test according to the procedures in
Sec. 63.7530(b). In recalculating the maximum chlorine input and
establishing the new operating limits, you are not required to conduct
fuel analyses for and include the fuels described in Sec.
63.7510(a)(2)(i) through (iii).
(5) If you demonstrate compliance with an applicable mercury
emission limit through fuel analysis, and you plan to burn a new type
of fuel, you must recalculate the mercury emission rate using Equation
13 of Sec. 63.7530 according to the procedures specified in paragraphs
(a)(5)(i) through (iii) of this section. You are not required to
conduct fuel analyses for the fuels described in Sec. 63.7510(a)(2)(i)
through (iii). You may exclude the fuels described in Sec.
63.7510(a)(2)(i) through (iii) when recalculating the mercury emission
rate.
(i) You must determine the mercury concentration for any new fuel
type in units of pounds per million Btu, based on supplier data or your
own fuel analysis, according to the provisions in your site-specific
fuel analysis plan developed according to Sec. 63.7521(b).
(ii) You must determine the new mixture of fuels that will have the
highest content of mercury.
(iii) Recalculate the mercury emission rate from your boiler or
process heater under these new conditions using Equation 13 of Sec.
63.7530. The recalculated mercury emission rate must be less than the
applicable emission limit.
(6) If you demonstrate compliance with an applicable mercury
emission limit through performance testing, and you plan to burn a new
type of fuel or a new mixture of fuels, you must recalculate the
maximum mercury input using Equation 8 of Sec. 63.7530. If the results
of recalculating the maximum mercury input using Equation 8 of Sec.
63.7530 are higher than the maximum mercury input level established
during the previous performance test, then you must conduct a new
performance test within 60 days of burning the new fuel type or fuel
mixture according to the procedures in Sec. 63.7520 to demonstrate
that the mercury emissions do not exceed the emission limit. You must
also establish new operating limits based on this performance test
according to the procedures in Sec. 63.7530(b). You are not required
to conduct fuel analyses for the fuels described in Sec.
63.7510(a)(2)(i) through (iii). You may exclude the fuels described in
Sec. 63.7510(a)(2)(i) through (iii) when recalculating the mercury
emission rate.
(7) If your unit is controlled with a fabric filter, and you
demonstrate continuous compliance using a bag leak detection system,
you must initiate corrective action within 1 hour of a bag leak
detection system alert and complete corrective actions as soon as
practical, and operate and maintain the fabric filter system such that
the periods which would cause an alert are no more than 5 percent of
the operating time during a 6-month period. You must also keep records
of the date, time, and duration of each alert, the time corrective
action was initiated and completed, and a brief description of the
cause of the alert and the corrective action taken. You must also
record the percent of the operating time during each 6-month period
that the conditions exist for an alert. In calculating this operating
time percentage, if inspection of the fabric filter demonstrates that
no corrective action is required, no alert time is counted. If
corrective action is required, each alert shall be counted as a minimum
of 1 hour. If you take longer than 1 hour to initiate corrective
action, the alert time shall be counted as the actual amount of time
taken to initiate corrective action.
(8) To demonstrate compliance with the applicable alternative CO
CEMS emission limit listed in Tables 1, 2, or 11 through 13 to this
subpart, you must meet the requirements in paragraphs (a)(8)(i) through
(iv) of this section.
(i) Continuously monitor CO according to Sec. Sec. 63.7525(a) and
63.7535.
(ii) Maintain a CO emission level below or at your applicable
alternative CO CEMS-based standard in Tables 1 or 2 or 11 through 13 to
this subpart at all times the affected unit is operating.
(iii) Keep records of CO levels according to Sec. 63.7555(b).
(iv) You must record and make available upon request results of CO
CEMS performance audits, dates and duration of periods when the CO CEMS
is out of control to completion of the corrective actions necessary to
return the CO CEMS to operation consistent with your site-specific
monitoring plan.
(9) The owner or operator of a boiler or process heater using a PM
CPMS or a PM CEMS to meet requirements of this subpart shall install,
certify, operate, and maintain the PM CPMS or PM CEMS in accordance
with your site-specific monitoring plan as required in Sec.
63.7505(d).
(10) If your boiler or process heater has a heat input capacity of
10 million Btu per hour or greater, you must conduct an annual tune-up
of the boiler or process heater to demonstrate continuous compliance as
specified in paragraphs (a)(10)(i) through (vi) of this section. This
frequency does not apply to limited-use boilers and process heaters, as
defined in Sec. 63.7575, or units with continuous oxygen trim systems
that maintain an optimum air to fuel ratio.
(i) As applicable, inspect the burner, and clean or replace any
components of the burner as necessary (you may delay the burner
inspection until the next scheduled unit shutdown). Units that produce
electricity for sale may delay the burner inspection until the first
outage, not to exceed 36 months from the previous inspection. At units
where entry into a piece of process equipment or into a storage vessel
is required to complete the tune-up inspections, inspections are
required only during planned entries into the storage vessel or process
equipment;
(ii) Inspect the flame pattern, as applicable, and adjust the
burner as necessary to optimize the flame pattern. The adjustment
should be consistent with the manufacturer's specifications, if
available;
(iii) Inspect the system controlling the air-to-fuel ratio, as
applicable, and ensure that it is correctly calibrated and functioning
properly (you may delay the inspection until the next scheduled unit
shutdown). Units that produce electricity for sale may delay the
inspection until the first outage, not to exceed 36 months from the
previous inspection;
(iv) Optimize total emissions of CO. This optimization should be
consistent with the manufacturer's specifications, if available, and
with any NOX requirement to which the unit is subject;
(v) Measure the concentrations in the effluent stream of CO in
parts per million, by volume, and oxygen in volume percent, before and
after the adjustments are made (measurements may be either on a dry or
wet basis, as long as it is the same basis before and after the
adjustments are made). Measurements may be taken using a portable CO
analyzer; and
(vi) Maintain on-site and submit, if requested by the
Administrator, an annual report containing the information in
paragraphs (a)(10)(vi)(A) through (C) of this section,
(A) The concentrations of CO in the effluent stream in parts per
million by volume, and oxygen in volume percent, measured at high fire
or typical operating load, before and after the tune-up of the boiler
or process heater;
(B) A description of any corrective actions taken as a part of the
tune-up; and
[[Page 7181]]
(C) The type and amount of fuel used over the 12 months prior to
the tune-up, but only if the unit was physically and legally capable of
using more than one type of fuel during that period. Units sharing a
fuel meter may estimate the fuel used by each unit.
(11) If your boiler or process heater has a heat input capacity of
less than 10 million Btu per hour (except as specified in paragraph
(a)(12) of this section), you must conduct a biennial tune-up of the
boiler or process heater as specified in paragraphs (a)(10)(i) through
(vi) of this section to demonstrate continuous compliance.
(12) If your boiler or process heater has a continuous oxygen trim
system that maintains an optimum air to fuel ratio, or a heat input
capacity of less than or equal to 5 million Btu per hour and the unit
is in the units designed to burn gas 1; units designed to burn gas 2
(other); or units designed to burn light liquid subcategories, or meets
the definition of limited-use boiler or process heater in Sec.
63.7575, you must conduct a tune-up of the boiler or process heater
every 5 years as specified in paragraphs (a)(10)(i) through (vi) of
this section to demonstrate continuous compliance. You may delay the
burner inspection specified in paragraph (a)(10)(i) of this section
until the next scheduled or unscheduled unit shutdown, but you must
inspect each burner at least once every 72 months.
(13) If the unit is not operating on the required date for a tune-
up, the tune-up must be conducted within 30 calendar days of startup.
(14) If you are using a CEMS measuring mercury emissions to meet
requirements of this subpart you must install, certify, operate, and
maintain the mercury CEMS as specified in paragraphs (a)(14)(i) and
(ii) of this section.
(i) Operate the mercury CEMS in accordance with performance
specification 12A of 40 CFR part 60, appendix B or operate a sorbent
trap based integrated monitor in accordance with performance
specification 12B of 40 CFR part 60, appendix B. The duration of the
performance test must be the maximum of 30 unit operating days or 720
hours. For each day in which the unit operates, you must obtain hourly
mercury concentration data, and stack gas volumetric flow rate data.
(ii) If you are using a mercury CEMS, you must install, operate,
calibrate, and maintain an instrument for continuously measuring and
recording the mercury mass emissions rate to the atmosphere according
to the requirements of performance specifications 6 and 12A of 40 CFR
part 60, appendix B, and quality assurance procedure 6 of 40 CFR part
60, appendix F.
(15) If you are using a CEMS to measure HCl emissions to meet
requirements of this subpart, you must install, certify, operate, and
maintain the HCl CEMS as specified in paragraphs (a)(15)(i) and (ii) of
this section. This option for an affected unit takes effect on the date
a final performance specification for an HCl CEMS is published in the
Federal Register or the date of approval of a site-specific monitoring
plan.
(i) Operate the continuous emissions monitoring system in
accordance with the applicable performance specification in 40 CFR part
60, appendix B. The duration of the performance test must be the
maximum of 30 unit operating days or 720 hours. For each day in which
the unit operates, you must obtain hourly HCl concentration data, and
stack gas volumetric flow rate data.
(ii) If you are using a HCl CEMS, you must install, operate,
calibrate, and maintain an instrument for continuously measuring and
recording the HCl mass emissions rate to the atmosphere according to
the requirements of the applicable performance specification of 40 CFR
part 60, appendix B, and the quality assurance procedures of 40 CFR
part 60, appendix F.
(16) If you demonstrate compliance with an applicable TSM emission
limit through performance testing, and you plan to burn a new type of
fuel or a new mixture of fuels, you must recalculate the maximum TSM
input using Equation 9 of Sec. 63.7530. If the results of
recalculating the maximum TSM input using Equation 9 of Sec. 63.7530
are higher than the maximum total selected input level established
during the previous performance test, then you must conduct a new
performance test within 60 days of burning the new fuel type or fuel
mixture according to the procedures in Sec. 63.7520 to demonstrate
that the TSM emissions do not exceed the emission limit. You must also
establish new operating limits based on this performance test according
to the procedures in Sec. 63.7530(b). You are not required to conduct
fuel analyses for the fuels described in Sec. 63.7510(a)(2)(i) through
(iii). You may exclude the fuels described in Sec. 63.7510(a)(2)(i)
through (iii) when recalculating the TSM emission rate.
(17) If you demonstrate compliance with an applicable TSM emission
limit through fuel analysis for solid or liquid fuels, and you plan to
burn a new type of fuel, you must recalculate the TSM emission rate
using Equation 14 of Sec. 63.7530 according to the procedures
specified in paragraphs (a)(5)(i) through (iii) of this section. You
are not required to conduct fuel analyses for the fuels described in
Sec. 63.7510(a)(2)(i) through (iii). You may exclude the fuels
described in Sec. 63.7510(a)(2)(i) through (iii) when recalculating
the TSM emission rate.
(i) You must determine the TSM concentration for any new fuel type
in units of pounds per million Btu, based on supplier data or your own
fuel analysis, according to the provisions in your site-specific fuel
analysis plan developed according to Sec. 63.7521(b).
(ii) You must determine the new mixture of fuels that will have the
highest content of TSM.
(iii) Recalculate the TSM emission rate from your boiler or process
heater under these new conditions using Equation 14 of Sec. 63.7530.
The recalculated TSM emission rate must be less than the applicable
emission limit.
(18) If you demonstrate continuous PM emissions compliance with a
PM CPMS you will use a PM CPMS to establish a site-specific operating
limit corresponding to the results of the performance test
demonstrating compliance with the PM limit. You will conduct your
performance test using the test method criteria in Table 5 of this
subpart. You will use the PM CPMS to demonstrate continuous compliance
with this operating limit. You must repeat the performance test
annually and reassess and adjust the site-specific operating limit in
accordance with the results of the performance test.
(i) To determine continuous compliance, you must record the PM CPMS
output data for all periods when the process is operating and the PM
CPMS is not out-of-control. You must demonstrate continuous compliance
by using all quality-assured hourly average data collected by the PM
CPMS for all operating hours to calculate the arithmetic average
operating parameter in units of the operating limit (milliamps) on a
30-day rolling average basis, updated at the end of each new boiler or
process heater operating hour.
(ii) For any deviation of the 30-day rolling PM CPMS average value
from the established operating parameter limit, you must:
(A) Within 48 hours of the deviation, visually inspect the air
pollution control device (APCD);
(B) If inspection of the APCD identifies the cause of the
deviation, take corrective action as soon as possible and return the PM
CPMS measurement to within the established value; and
[[Page 7182]]
(C) Within 30 days of the deviation or at the time of the annual
compliance test, whichever comes first, conduct a PM emissions
compliance test to determine compliance with the PM emissions limit and
to verify or re-establish the CPMS operating limit. You are not
required to conduct additional testing for any deviations that occur
between the time of the original deviation and the PM emissions
compliance test required under this paragraph.
(iii) PM CPMS deviations from the operating limit leading to more
than four required performance tests in a 12-month operating period
constitute a separate violation of this subpart.
(19) If you choose to comply with the PM filterable emissions limit
by using PM CEMS you must install, certify, operate, and maintain a PM
CEMS and record the output of the PM CEMS as specified in paragraphs
(a)(19)(i) through (vii) of this section. The compliance limit will be
expressed as a 30-day rolling average of the numerical emissions limit
value applicable for your unit in Tables 1 or 2 or 11 through 13 of
this subpart.
(i) Install and certify your PM CEMS according to the procedures
and requirements in Performance Specification 11--Specifications and
Test Procedures for Particulate Matter Continuous Emission Monitoring
Systems at Stationary Sources in Appendix B to part 60 of this chapter,
using test criteria outlined in Table V of this rule. The reportable
measurement output from the PM CEMS must be expressed in units of the
applicable emissions limit (e.g., lb/MMBtu, lb/MWh).
(ii) Operate and maintain your PM CEMS according to the procedures
and requirements in Procedure 2-- Quality Assurance Requirements for
Particulate Matter Continuous Emission Monitoring Systems at Stationary
Sources in Appendix F to part 60 of this chapter.

CEMS at least once annually.
(B) You must conduct the relative correlation audit (RCA) for your
PM CEMS at least once every 3 years.
(iii) Collect PM CEMS hourly average output data for all boiler
operating hours except as indicated in paragraph (i) of this section.
(iv) Calculate the arithmetic 30-day rolling average of all of the
hourly average PM CEMS output data collected during all nonexempt
boiler or process heater operating hours.
(v) You must collect data using the PM CEMS at all times the unit
is operating and at the intervals specified this paragraph (a), except
for periods of monitoring system malfunctions, repairs associated with
monitoring system malfunctions, and required monitoring system quality
assurance or quality control activities.
(vi) You must use all the data collected during all boiler or
process heater operating hours in assessing the compliance with your
operating limit except:
(A) Any data collected during monitoring system malfunctions,
repairs associated with monitoring system malfunctions, or required
monitoring system quality assurance or control activities conducted
during monitoring system malfunctions in calculations and report any
such periods in your annual deviation report;
(B) Any data collected during periods when the monitoring system is
out of control as specified in your site-specific monitoring plan,
repairs associated with periods when the monitoring system is out of
control, or required monitoring system quality assurance or control
activities conducted during out of control periods in calculations used
to report emissions or operating levels and report any such periods in
your annual deviation report;
(C) Any data recorded during periods of startup or shutdown.
(vii) You must record and make available upon request results of PM
CEMS system performance audits, dates and duration of periods when the
PM CEMS is out of control to completion of the corrective actions
necessary to return the PM CEMS to operation consistent with your site-
specific monitoring plan.
(b) You must report each instance in which you did not meet each
emission limit and operating limit in Tables 1 through 4 or 11 through
13 to this subpart that apply to you. These instances are deviations
from the emission limits or operating limits, respectively, in this
subpart. These deviations must be reported according to the
requirements in Sec. 63.7550.
(c) If you elected to demonstrate that the unit meets the
specification for mercury for the unit designed to burn gas 1
subcategory, you must follow the sampling frequency specified in
paragraphs (c)(1) through (4) of this section and conduct this sampling
according to the procedures in Sec. 63.7521(f) through (i).
(1) If the initial mercury constituents in the gaseous fuels are
measured to be equal to or less than half of the mercury specification
as defined in Sec. 63.7575, you do not need to conduct further
sampling.
(2) If the initial mercury constituents are greater than half but
equal to or less than 75 percent of the mercury specification as
defined in Sec. 63.7575, you will conduct semi-annual sampling. If 6
consecutive semi-annual fuel analyses demonstrate 50 percent or less of
the mercury specification, you do not need to conduct further sampling.
If any semi-annual sample exceeds 75 percent of the mercury
specification, you must return to monthly sampling for that fuel, until
12 months of fuel analyses again are less than 75 percent of the
compliance level.
(3) If the initial mercury constituents are greater than 75 percent
of the mercury specification as defined in Sec. 63.7575, you will
conduct monthly sampling. If 12 consecutive monthly fuel analyses
demonstrate 75 percent or less of the mercury specification, you may
decrease the fuel analysis frequency to semi-annual for that fuel.
(4) If the initial sample exceeds the mercury specification as
defined in Sec. 63.7575, each affected boiler or process heater
combusting this fuel is not part of the unit designed to burn gas 1
subcategory and must be in compliance with the emission and operating
limits for the appropriate subcategory. You may elect to conduct
additional monthly sampling while complying with these emissions and
operating limits to demonstrate that the fuel qualifies as another gas
1 fuel. If 12 consecutive monthly fuel analyses samples are at or below
the mercury specification as defined in Sec. 63.7575, each affected
boiler or process heater combusting the fuel can elect to switch back
into the unit designed to burn gas 1 subcategory until the mercury
specification is exceeded.
(d) For startup and shutdown, you must meet the work practice
standards according to item 5 of Table 3 of this subpart.

category.
Electric utility steam generating unit (EGU) means a fossil fuel-
fired combustion unit of more than 25 megawatts electric (MWe) that
serves a generator that produces electricity for sale. A fossil fuel-
fired unit that cogenerates steam and electricity and supplies more
than one-third of its potential electric output capacity and more than
25 MWe output to any utility power distribution system for sale is
considered an electric utility steam generating unit. To be ``capable
of combusting'' fossil fuels, an EGU would need to have these fuels
allowed in their operating permits and have the appropriate fuel
handling facilities on-site or otherwise available (e.g., coal handling
equipment, including coal storage area, belts and conveyers,
pulverizers, etc.; oil storage facilities). In addition, fossil fuel-
fired EGU means any EGU that fired fossil fuel for more than 10.0

voluntary consensus standard or practice (VCS) or EPA method that
includes collection of a minimum of three composite fuel samples, with
each composite
[[Page 7189]]
consisting of a minimum of three increments collected at approximately
equal intervals over the test period.
(2) An equivalent sample compositing procedure means a published
VCS or EPA method to systematically mix and obtain a representative
subsample (part) of the composite sample.
(3) An equivalent sample preparation procedure means a published
VCS or EPA method that: Clearly states that the standard, practice or
method is appropriate for the pollutant and the fuel matrix; or is
cited as an appropriate sample preparation standard, practice or method
for the pollutant in the chosen VCS or EPA determinative or analytical
method.
(4) An equivalent procedure for determining heat content means a
published VCS or EPA method to obtain gross calorific (or higher
heating) value.
(5) An equivalent procedure for determining fuel moisture content
means a published VCS or EPA method to obtain moisture content. If the
sample analysis plan calls for determining metals (especially the
mercury, selenium, or arsenic) using an aliquot of the dried sample,
then the drying temperature must be modified to prevent vaporizing
these metals. On the other hand, if metals analysis is done on an ``as
received'' basis, a separate aliquot can be dried to determine moisture
content and the metals concentration mathematically adjusted to a dry
basis.
(6) An equivalent pollutant (mercury, HCl) determinative or
analytical procedure means a published VCS or EPA method that clearly
states that the standard, practice, or method is appropriate for the
pollutant and the fuel matrix and has a published detection limit equal

unit designed to burn coal/solid fossil fuel subcategory that fire coal
refuse.
* * * * *
Fuel cell means a boiler type in which the fuel is dropped onto
suspended fixed grates and is fired in a pile. The refractory-lined
fuel cell uses combustion air preheating and positioning of secondary
and tertiary air injection ports to improve boiler efficiency.
Fluidized bed, dutch oven, pile burner, hybrid suspension grate, and
suspension burners are not part of the fuel cell subcategory.
Fuel type means each category of fuels that share a common name or

whether such emission points or stations are major sources, even when
emission points are in a contiguous area or under common control;
(2) Emissions from processes, operations, or equipment that are not
part of the same facility, as defined in this section, shall not be
aggregated; and
(3) For facilities that are production field facilities, only HAP

Period of gas curtailment or supply interruption means a period of
time during which the supply of gaseous fuel to an affected boiler or
process heater is restricted or halted for reasons beyond the control
of the facility. The act of entering into a contractual agreement with
a supplier of natural gas established for curtailment purposes does not
constitute a reason that is under the control of a facility for the
purposes of this definition. An increase in the cost or unit price of
natural gas due to normal market fluctuations not during periods of
supplier delivery restriction does not constitute a period of natural
gas curtailment or supply interruption. On-site gaseous fuel system
emergencies or equipment failures qualify as periods of supply
interruption when the emergency or failure is beyond the control of the
facility.
Pile burner means a boiler design incorporating a design where the
anticipated biomass fuel has a high relative moisture content. Grates
serve to support the fuel, and underfire air flowing up through the
grates provides oxygen for combustion, cools the grates, promotes
turbulence in the fuel bed, and fires the fuel. The most common form of
pile burning is the dutch oven.
Process heater means an enclosed device using controlled flame, and
the unit's primary purpose is to transfer heat indirectly to a process
material (liquid, gas, or solid) or to a heat transfer material (e.g.,
glycol or a mixture of glycol and water) for use in a process unit,
instead of generating steam. Process heaters are devices in which the
combustion gases do not come into direct contact with process
materials. A device combusting solid waste, as defined in Sec. 241.3
of this chapter, is not a process heater unless the device is exempt
from the definition of a solid waste incineration unit as provided in
section 129(g)(1) of the Clean Air Act. Process heaters do not include
units used for comfort heat or space heat, food preparation for on-site
consumption, or autoclaves. Waste heat process heaters are excluded
from this definition.
