National Emission Standards for Hazardous Air Pollutants for the
Portland Cement Manufacturing Industry
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is taking direct
final action to amend the National Emission Standards for Hazardous Air
Pollutants for the Portland Cement Manufacturing Industry. This direct
final rule provides, for a period of 1 year, an additional compliance
alternative for sources that would otherwise be required to use an HCl
CEMS to demonstrate compliance with the HCl emissions limit. This
compliance alternative is needed due to the current unavailability of a
calibration gas used for quality assurance purposes. This direct final
rule also restores regulatory text requiring the reporting of clinker
production and kiln feed rates that was deleted inadvertently.
DATES: This rule is effective on September 8, 2016 without further
notice, unless the EPA receives significant adverse comment by August
24, 2016. If the EPA receives significant adverse comment, we will
publish a timely withdrawal in the Federal Register informing the
public that the rule will not take effect.

I. General Information
A. Why is the EPA using a direct final rule?
The EPA is publishing this direct final rule without a prior
proposed rule because we view this as a noncontroversial action and do
not anticipate significant adverse comment. However, in the ``Proposed
Rules'' section of this Federal Register, we are publishing a separate
document that will serve as the proposed rule to amend the National
Emission Standards for Hazardous Air Pollutants for the Portland Cement
Manufacturing Industry, if EPA receives significant adverse comments on
this direct final rule. We will not institute a second comment period
on this action. Any parties interested in commenting must do so at this
time. For further information about commenting on this rule, see the
ADDRESSES section of this document.
If the EPA receives significant adverse comment on all or a
distinct portion of this direct final rule, we will publish a timely
withdrawal in the Federal Register informing the public that some or
all of this direct final rule will not take effect. We would address
all public comments in any subsequent final rule based on the proposed
rule.
B. Does this direct final rule apply to me?

Triangle Park, North Carolina 27711, Attention Docket ID No. EPA-HQ-
OAR-2011-0817.
II. What are the amendments made by this direct final rule?
In response to a concern raised by a stakeholder regarding the
availability of calibration gases for HCl continuous monitoring
compliance, this direct final rule amends 40 CFR 63.1349(b)(6) of the
performance testing requirements for HCl by adding an alternative
method for performance testing. Under the current rule, the owner or
operator of a kiln subject to the emission limits for HCl in 40 CFR
63.1343 may demonstrate compliance by one of the following methods:
An owner or operator of a kiln may demonstrate compliance
by operating a continuous emissions monitoring system (CEMS) meeting
the requirements of performance specification 15 (PS-15), PS-18, or any
other PS for HCl CEMS in appendix B to part 60, with compliance based
on a 30-kiln operating day rolling average.
If the kiln is controlled using a wet scrubber, tray
tower, or dry scrubber, the owner or operator, as an alternative to
using a CEMS, may demonstrate compliance with the HCl limit using one
of two options, described below.
Under both options, a performance test must be conducted by the
owner or operator using Method 321. Under the first option, while
conducting the Method 321 performance test (note Method 321 is the HCl
stack testing performance method required by this rule), the owner or
operator simultaneously measures a control device parameter and
establishes a site-specific parameter limit that will be continuously
monitored to determine compliance. If the kiln is controlled using a
wet scrubber or tray tower, the owner or operator would monitor the
pressure drop across the scrubber and/or liquid flow rate and pH during
the HCl performance test. If the kiln is controlled using a dry
scrubber, the sorbent injection rate would be monitored during the
performance test. Under the second option, the owner or operator may
establish sulfur dioxide (SO2) as the operating parameter by
measuring SO2 emissions using a CEMS simultaneously with the
Method 321 test and establishing the site-specific SO2 limit
that will be continuously monitored to determine compliance with the
HCl limit.
The current rule requires that if a source chooses to monitor HCl
emissions using a CEMS, they must do so in accordance with PS-15, PS-
18, or any other PS for HCl CEMS in appendix B to part 60 of this
chapter. (See 40 CFR part 60 appendix B.) Quality assurance procedures
for HCl CEMS require that they be capable of reading HCl concentrations
that span a range of possible emission levels below as well as above
expected HCl emission concentrations. These quality assurance
procedures require the use of National Institute of Standards and
Technology (NIST)-traceable calibration gases for HCl.
Following our decision to create PS-18 and Procedure 6 for HCl
continuous monitoring in 2012, the EPA worked with NIST and commercial
gas vendors on development of NIST-traceable HCl gas standards to
support the PS-18 and Portland Cement Maximum Achievable Control
Technology (MACT) rulemaking. While some of the low HCl concentration
(<10 parts per million, or ppm) NIST-traceable gases have been
available on a limited basis since 2013, the full range of HCl
concentrations required to support all HCl emissions monitoring
technologies (including integrated path that requires concentrations
100 times higher) are not widely available at this time.
The approach used by NIST in 2013 was to certify the Research Gas
Material (RGM) cylinders as primary gas standards. These cylinders
contain HCl gas and are provided to NIST by vendors for NIST
certification, and subsequently used by the vendors as transfer
standards to prepare the Gas Manufacturer Intermediate Standards
(GMIS). The GMIS cylinders are then used to produce NIST-traceable gas
cylinders that are sold commercially.\1\ The initial approach used by
NIST to certify the RGM cylinders was not viable in the long term as
the instrumentation used by NIST largely depleted the HCl RGM gas
volume, leaving little gas in the cylinder for the vendors to use in
preparing GMIS materials. Because of this concern, NIST initiated
development of an improved RGM certification procedure. The development
of both the initial and more recently improved approach has been
hampered by the challenges presented in handling HCl gas. HCl gas is
extremely reactive and difficult to handle in both gas cylinders and
analytically. As such, it has taken considerable time for NIST to
optimize the new analytical equipment and approach to achieve the
necessary uncertainty requirements (e.g., <1 percent uncertainty).
---------------------------------------------------------------------------

Gaseous Calibration Standards, U.S. Environmental Protection Agency
Office of Research and Development, EPA/600/R-12/531, May 2012.
---------------------------------------------------------------------------
In addition, the commercial establishment of NIST-traceable gases
is dependent on collaboration between NIST and the specialty gas
vendors. There are a limited number of vendors providing the stable,
accurate, low and high concentration cylinder gases to NIST to certify
as RGMs. NIST is now receiving a regular supply of candidate RGM
cylinders from these vendors and is beginning work on higher
concentration HCl gas standards needed to support integrated path HCl
monitors (IP-CEMS). Once the RGMs are available, the specialty gas
vendors must complete a series of procedures to establish the certainty
of their products which adds to the time to achieve wide commercial
availability.
As a result, the EPA is providing, for a period of 1 year, an
additional compliance alternative for sources that would otherwise be
required to use an HCl CEMS. In this alternative, the HCl CEMS is still
required to be installed and operated, but actual compliance with the
HCl emissions limit is determined by a three run stack test. The HCl
CEMS will still provide a continuous readout of HCl emissions, but
because the CEMS will not be calibrated with the required NIST-
traceable calibration gases, the HCl measurement is not considered to
be sufficiently accurate on an absolute basis for compliance, but would
be sufficient to indicate any relative change in HCl emissions
occurring subsequent
[[Page 48358]]
to the compliance test. Therefore, the HCl CEMS under this alternative
would function as a continuous parameter monitor system (CPMS) as in
the case of the particulate matter (PM) CPMS requirement (see 78 FR
10014-10015, 10019-10020, February 12, 2013). Based on conversations
with gas vendors and NIST, we anticipate that NIST-traceable
calibration gases for HCl will be available in sufficient quantities
within one year of this notice (see J. Ryan, memo to S. Johnson, Docket
ID No. EPA-HQ-OAR-2011-0817, Status of NIST-Traceable Hydrogen Chloride
(HCl) Calibration Gases for Use With HCl Continuous Emissions
Monitoring Systems (CEMS) Under 40 CFR part 63, subpart LLL, June 22,
2016). Thus, this alternative will expire on July 25, 2017 and owner/
operators must have in place one of the original HCl compliance
demonstration alternatives (we anticipate HCl CEMS operated monitoring
equipment according to 40 CFR 63.1350(l)) by this date.
Under this new, temporary alternative, the owner or operator would
demonstrate initial compliance by conducting a performance test using
Method 321 and would monitor compliance with an operating parameter
limit through use of an HCl CPMS. For the HCl CPMS, the owner operator
would use the average HCl CPMS indicated output, typically displayed as
parts per million volume, wet basis HCl recorded at in-stack oxygen
concentration during the HCl performance test to establish the
operating limit. To determine continuous compliance with the operating
limit, the owner or operator would record the indicated HCl CPMS output
data for all periods when the process is operating and use all the HCl
CPMS data, except data obtained during times of monitor malfunctions.
Thus, continuous compliance with the operating limit would be
demonstrated by using all valid hourly average data collected by the
HCl CPMS for all operating hours to calculate the arithmetic average
operating parameter in units of the operating limit (indicated ppm) on
a 30-kiln operating day rolling average basis, updated at the end of
each new kiln operating day. An exceedance of the kiln 30-day operating
limit would trigger evaluation of the control system operation and
resetting the operating limit based on a new correlation with
performance testing. For kilns with inline raw mills, performance
testing and monitoring HCl to establish the site specific operating
limit must be conducted during both raw mill on and raw mill off
conditions.
As is the case for the PM CPMS requirements (see 40 CFR
63.1349(b)(1)(i)), this alternative includes a scaling factor of 75
percent of the emission standard as a benchmark (2.25 parts per million
volume, dry basis @ 7-percent oxygen). Sources that choose this option
will conduct a Method 321 test to determine compliance with the HCl
emissions standard and during this testing will also monitor their HCl
CPMS output in indicated ppm to determine where their HCl CPMS output
would intersect 75 percent of their allowed HCl emissions, and set
their operating level at that ppm output. This scaling procedure
alleviates re-testing concerns for sources that operate well below the
emission limit and provides greater operational flexibility while
assuring continuous compliance with the HCl emission standard. For
sources whose Method 321 compliance tests place them at or above 75
percent of the emission standard, their operating limit is determined
by the average of three Method 321 test runs (for sources with no
inline raw mill) or the time weighted average of six Method 321 test
runs (for kilns with inline raw mills). We believe that by adopting a
scaling factor as well as the use of 30 days of averaged HCl CPMS
measurements, the parametric limit in no way imposes a stringency level
higher than the level of the HCl emissions standard and will avoid
triggering unnecessary retests for many facilities, especially for the
lower-emitting sources.
In addition to adding the interim testing and monitoring provisions
for HCl, we are restoring a recordkeeping regulatory provision that was
deleted inadvertently during one of the recent rule revisions. The
provision in question is the former 40 CFR 63.1355(e). This provision
relates to the recordkeeping requirements for clinker production and
kiln feed rates. This requirement was added in the 2010 final
amendments and was not removed or revised in subsequent amendments to
the rule. This rulemaking restores this provision in the regulatory
text to ensure that the regulated community has a clear understanding
of the applicable compliance requirements.
III. Statutory and Executive Order Reviews
Additional information about these statutes and Executive Orders
can be found at http://www2.epa.gov/laws-regulations/laws-and-executive-orders.
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review
This action is not a significant regulatory action and was,
therefore, not submitted to the Office of Management and Budget (OMB)
for review.
B. Paperwork Reduction Act (PRA)
This action does not impose any new information collection burden
under the PRA. OMB has previously approved the information collection
activities contained in the existing regulation (40 CFR part 63,
subpart RRR) and has assigned OMB control number 2060-0416. This action
does not change the information collection requirements.
C. Regulatory Flexibility Act (RFA)
I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA. This
action will not impose any requirements on small entities. This action
does not create any new requirements or burdens and no costs are
associated with this direct final action.
D. Unfunded Mandates Reform Act (UMRA)
This action does not contain an unfunded mandate as described in
UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect
small governments. The action imposes no enforceable duty on any state,
local, or tribal governments or the private sector.
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.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have tribal implications, as specified in
Executive Order 13175. It will neither impose substantial direct
compliance costs on federally recognized tribal governments, nor
preempt tribal law. The EPA is aware of one tribally owned Portland
cement facility currently subject to 40 CFR part 63, subpart LLL that
will be subject to this direct final rule. However, the provisions of
this direct final rule are not expected to impose new or substantial
direct compliance costs on Tribal governments since the provisions in
this direct final rule are
[[Page 48359]]
adding an alternative to the HCl monitoring provisions, adding an
option which provides operational flexibility. 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 as applying to those
regulatory actions that concern environmental health or safety risks
that the EPA has reason to believe may disproportionately affect
children, per the definition of ``covered regulatory action'' in
section 2-202 of the Executive Order. This action is not subject to
Executive Order 13045 because it does not concern an environmental
health risk or safety risk.
H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This action is not subject to Executive Order 13211 because it is
not a significant regulatory action under Executive Order 12866.
I. National Technology Transfer and Advancement Act (NTTAA)
This rulemaking does not involve technical standards.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
The EPA believes that this action does not have disproportionately
high and adverse human health or environmental effects on minority
populations, low-income populations, or indigenous peoples, as
specified in Executive Order 12898 (59 FR 7629, February 16, 1994).
This action does not affect the level of protection provided to human
health or the environment.
K. Congressional Review Act (CRA)
This action is subject to the CRA, and the EPA will submit a rule
report to each House of the Congress and to the Comptroller General of
the United States. This action is not a ``major rule'' as defined by 5
U.S.C. 804(2).

For the reasons stated in the preamble, the Environmental
Protection Agency is amending title 40, chapter I, part 63 of the Code
of Federal Regulations (CFR) as follows:
PART 63--NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS
FOR SOURCE CATEGORIES
0
1. The authority citation for part 63 continues to read as follows:
Authority: 42 U.S.C. 7401, et seq.
Subpart LLL--National Emission Standards for Hazardous Air
Pollutants for the Portland Cement Manufacturing Industry

2. Section 63.1349 is amended by adding paragraph (b)(6)(v) to read as
follows:
Sec. 63.1349 Performance testing requirements.
* * * * *
(b) * * *
(6) * * *
(v) As an alternative to paragraph (b)(6)(ii) of this section, the
owner or operator may demonstrate initial compliance by conducting a
performance test using Method 321 of appendix A to this part. You must
also monitor continuous performance through use of an HCl CPMS
according to paragraphs (b)(6)(v)(A) through (H) of this section. For
kilns with inline raw mills, compliance testing and monitoring HCl to
establish the site specific operating limit must be conducted during
both raw mill on and raw mill off conditions.
(A) For your HCl CPMS, you must establish a 30 kiln operating day
site-specific operating limit. If your HCl performance test
demonstrates your HCl emission levels to be less than 75 percent of
your emission limit (2.25 ppmvd @7% O2), you must use the
time weighted average HCl CPMS indicated value recorded during the HCl
compliance test (typically measured as ppmvw HCl at stack O2
concentration, but a dry, oxygen corrected value would also suffice),
your HCl instrument zero output value, and the time weighted average
HCl result of your compliance test to establish your operating limit.
If your HCl compliance test demonstrates your HCl emission levels to be
at or above 75 percent of your emission limit (2.25 ppmvd @7%
O2), you must use the time weighted average HCl CPMS
indicated value recorded during the HCl compliance test as your
operating limit. You must use the HCl CPMS indicated signal data to
demonstrate continuous compliance with your operating limit.
(1) Your HCl CPMS must provide a ppm HCl concentration output and
the establishment of its relationship to manual reference method
measurements must be determined in units of indicated ppm. The
instrument signal may be in ppmvw or ppmvd and the signal may be a
measurement of HCl at in-stack concentration or a corrected oxygen
concentration. Once the relationship between the indicated output of
the HCl CPMS and the reference method test results is established, the
HCl CPMS instrument measurement basis (ppmvw or ppmvd, or oxygen
correction basis) must not be altered. Likewise, any setting that
impacts the HCl CPMS indicated HCl response must remain fixed after the
site-specific operating limit is set.
(2) Your HCl CPMS operating range must be capable of reading HCl
concentrations from zero to a level equivalent to 125 percent of the
highest expected value during mill off operation. If your HCl CPMS is
an auto-ranging instrument capable of multiple scales, the primary
range of the instrument must be capable of reading an indicated HCl
concentration from zero to 10 ppm.
(3) During the initial performance test of a kiln with an inline
raw mill, or any such subsequent performance test that demonstrates
compliance with the HCl limit, record and average the indicated ppm HCl
output values from the HCl CPMS for each of the six periods
corresponding to the compliance test runs (e.g., average each of your
HCl CPMS output values for six corresponding Method 321 test runs).
With the average values of the six test runs, calculate the average of
the three mill on test runs and the average of the three mill off test
runs. Calculate the time weighted result using the average of the three
mill on tests and the average of the three mill off tests and the
previous annual ratio of mill on/mill off operations. Kilns without an
inline raw mill will conduct three compliance tests and calculate the
average monitor output values corresponding to these three test runs
and not use time weighted values to determine their site specific
operating limit.
(B) Determine your operating limit as specified in paragraphs
(b)(6)(i) or (iii) of this section. If your HCl performance test
demonstrates your HCl emission levels to be below 75 percent of your
emission limit, kilns with inline raw mills will use the time weighted
average indicated HCl ppm concentration CPMS
[[Page 48360]]
value recorded during the HCl compliance test, the zero value output
from your HCl CPMS, and the time weighted average HCl result of your
compliance test to establish your operating limit. Kilns without inline
raw mills will not use a time weighted average value to establish their
operating limit. If your time weighted HCl compliance test demonstrates
your HCl emission levels to be at or above 75 percent of your emission
limit, you will use the time weighted HCl CPMS indicated ppm value
recorded during the HCl compliance test to establish your operating
limit. Kilns without inline raw mills will not use time weighted
compliance test results to make this determination. You must verify an
existing operating limit or establish a new operating limit for each
kiln, after each repeated performance test.
(C) If the average of your three Method 321 compliance test runs
(for kilns without an inline raw mill) or the time weighted average of
your six Method 321 compliance test runs (for an kiln with an inline
raw mill) is below 75 percent of your HCl emission limit, you must
calculate an operating limit by establishing a relationship of the
average HCl CPMS indicated ppm to the Method 321 test average HCl
concentration using the HCl CPMS instrument zero, the average HCl CPMS
indicated values corresponding to the three (for kilns without inline
raw mills) or time weighted HCl CPMS indicated values corresponding to
the six (for kilns with inline raw mills) compliance test runs, and the
average HCl concentration (for kilns without raw mills) or average time
weighted HCl concentration (for kilns with inline raw mills) from the
Method 321 compliance test with the procedures in paragraphs
(b)(6)(v)(C)(1) through (5) of this section.
(1) Determine your HCl CPMS 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) If neither of the steps in paragraphs (b)(6)(v)(C)(1)(i)
through (ii) of this section are possible, you must use a zero output
value provided by the manufacturer.
(2) If your facility does not have an inline raw mill you will
determine your HCl CPMS indicated average in HCl ppm, and the average
of your corresponding three HCl compliance test runs, using equation
11a.
[GRAPHIC] [TIFF OMITTED] TR25JY16.018
Where:
Xi = The HCl CPMS data points for the three (or six) runs
constituting the performance test;
Yi = The HCl concentration value for the three (or six)
runs constituting the performance test; and
n = The number of data points.
(3) You will determine your HCl CPMS indicated average in HCl ppm,
and the average of your corresponding HCl compliance test runs, using
equation 11b. If you have an inline raw mill, use this same equation to
calculate a second three-test average for your mill off CPMS and
compliance test data.
[GRAPHIC] [TIFF OMITTED] TR25JY16.019
Where:
Xi = The HCl CPMS data points for the three runs
constituting the mill on OR mill off performance test;
Yi = The HCl concentration value for the three runs
constituting the mill on OR mill off performance test; and
n = The number of data points.
(4) With your instrument zero expressed in ppm, your average HCl
CPMS ppm value, and your HCl compliance test average, determine a
relationship of performance test HCl (as ppmvd @7% O2)
concentration per HCl CPMS indicated ppm with Equation 11c.
[GRAPHIC] [TIFF OMITTED] TR25JY16.020
Where:
R = The relative performance test concentration per indicated ppm
for your HCl CPMS;
Y1 = The average HCl concentration as ppmvd @7%
O2 during the performance test;
X1 = The average indicated ppm output from your HCl CPMS;
and
z = The ppm of your instrument zero determined from paragraph
(b)(6)(v)(C)(1) of this section.
(5) Determine your source specific 30 kiln operating day operating
limit using HC1 CPMS indicated value from Equation 11c in Equation 11d,
below. This sets your operating limit at the HC1 CPMS output value
corresponding to 75 percent of your emission limit.
[[Page 48361]]
[GRAPHIC] [TIFF OMITTED] TR25JY16.021
Where:
Ol = The operating limit for your HCl CPMS on a 30 kiln
operating day average, as indicated ppm;
L = 3 ppmvd @7% O2;
z = Your instrument zero, determined from paragraph (b)(6)(v)(C)(1)
of this section ; and
R = The relative performance test concentration per indicated ppm
for your HCl CPMS, from Equation 11c.
(D) If the average of your HCl compliance test runs is at or above
75 percent of your HCl emission limit (2.25 ppmvd@7% O2) you
must determine your operating limit by averaging the HCl CPMS output
corresponding to your HCl performance test runs that demonstrate
compliance with the emission limit using Equation 11e.
[GRAPHIC] [TIFF OMITTED] TR25JY16.022
Where:
Oh = Your site specific HCl CPMS operating limit, in
indicated ppm.
Xi = The HCl CPMS data points for all runs i.
n = The number of data points.
(E) To determine continuous compliance with the operating limit,
you must record the HCl CPMS indicated output data for all periods when
the process is operating and use all the HCl CPMS data for calculations
when the source is not out of control. You must demonstrate continuous
compliance with the operating limit by using all quality-assured hourly
average data collected by the HCl CPMS for all operating hours to
calculate the arithmetic average operating parameter in units of the
operating limit (ppmvw) on a 30 kiln operating day rolling average
basis, updated at the end of each new kiln operating day. Use Equation
11f to determine the 30 kiln operating day average.

value for the CPMS parameter over the previous 30 days of kiln
operation;
Hpvi = The hourly parameter value for hour i; and
n = The number of valid hourly parameter values collected over 30
kiln operating days.
(F) If you exceed the 30 kiln operating day operating limit, you
must evaluate the control system operation and re-set the operating
limit.
(G) The owner or operator of a kiln with an inline raw mill and
subject to limitations on HCl emissions must demonstrate initial
compliance by conducting separate performance tests while the raw mill
is on and while the raw mill is off. Using the fraction of time the raw
mill is on calculate your HCl CPMS limit as a weighted average of the
HCl CPMS indicated values measured during raw mill on and raw mill off
compliance testing using Equation 11g.

(4) If you monitor continuous performance through the use of an HCl
CPMS according to paragraphs (b)(6)(v)(A) through (H) of Sec. 63.1349,
for any exceedance of the 30 kiln operating day HCl CPMS average value
from the established operating limit, you must:
(i) Within 48 hours of the exceedance, visually inspect the APCD;
(ii) If inspection of the APCD identifies the cause of the
exceedance, take corrective action as soon as possible and return the
HCl CPMS measurement to within the established value; and
(iii) Within 30 days of the exceedance or at the time of the annual
compliance test, whichever comes first, conduct an HCl emissions
compliance test to determine compliance with the HCl emissions limit
and to verify or reestablish the HCl CPMS operating
[[Page 48362]]
limit within 45 days. You are not required to conduct additional
testing for any exceedances that occur between the time of the original
exceedance and the HCl emissions compliance test required under this
paragraph.
(iv) HCl CPMS exceedances leading to more than four required
performance tests in a 12-month process operating period (rolling
monthly) constitute a presumptive violation of this subpart.
