Disapproval of State Implementation Plan Revisions; Clark County,
Nevada
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The EPA is proposing to disapprove revisions to the Clark
County portion of the Nevada State Implementation Plan (SIP). The SIP
contains state and local regulations necessary to meet requirements of
the Clean Air Act (CAA or the Act). We are proposing to disapprove a
submission that would revise the SIP to include affirmative defense
provisions applicable to violations related to excess emissions during
equipment startup, shutdown and malfunction (SSM) events. We are taking
comments on this proposal and plan to follow with a final action.
DATES: Any comments must arrive by January 9, 2014.
ADDRESSES: Submit comments, identified by docket number EPA-R09-OAR-
2013-0778, by one of the following methods:
1. Federal eRulemaking Portal: www.regulations.gov. Follow the on-
line instructions.
2. Email: [email protected].
3. Mail or deliver: Andrew Steckel (Air-4), U.S. Environmental
Protection Agency Region IX, 75 Hawthorne Street, San Francisco, CA
94105-3901.
Instructions: All comments will be included in the public docket
without change and may be made available online at www.regulations.gov,
including any personal information provided, unless the comment
includes Confidential Business Information (CBI) or other information
whose disclosure is restricted by statute. Information that you
consider CBI or otherwise protected should be clearly identified as
such and should not be submitted through www.regulations.gov or email.

I. The State's Submittal
A. What regulation did the State submit?
Table 1 identifies the section of the Clark County Air Quality
Regulations (CCAQR) proposed for disapproval, with the dates that it
was amended by the Clark County Board of Commissioners (CCBC) and
submitted to EPA on behalf of the Clark County Department of Air
Quality and Environmental Management (DAQEM) by the State of Nevada
Division of Environmental Protection (NDEP).

for Excess Emissions Due to
Malfunctions, Startups, and

----------------------------------------------------------------------------------------------------------------
[[Page 74058]]
On March 1, 2011, NDEP's September 1, 2010 submission was deemed
complete by operation of law, pursuant to CAA section 110(k)(1).
The CCBC also decided to adopt or amend other sections of the
CCAQR, primarily addressing air pollution permit procedures, at the
same May 18, 2010 CCBC hearing, and included these revisions in the
same September 1, 2010 SIP submission. EPA has already taken action
upon the other revisions in the September 1, 2010 SIP submission. EPA
proposed a limited approval and limited disapproval of these other
revisions on July 24, 2012 (77 FR 43206) and finalized the limited
approval and limited disapproval on October 18, 2012 (77 FR 6403). EPA
did not address the revisions to CCAQR Section 25 in the July 24, 2012
proposal or October 18, 2012 final action. Today's action addresses the
remaining portion of NDEP's September 1, 2010 submission, specifically
CCAQR Section 25.
B. Are there other versions of the submitted regulation?
We are not certain when CCBC originally adopted Section 25, but
CCBC has amended it at the local level many times, most recently on May
18, 2010.\1\ EPA has not previously approved a version of Section 25
into the Nevada SIP.\2\ Therefore, the May 18, 2010 version of Section
25 is a new submittal to the SIP and is not replacing or amending pre-
existing requirements already approved into the SIP. EPA is today
reviewing only the May 18, 2010 version of Section 25 and the relevant
materials associated with it that were included in NDEP's September 1,
2010 SIP submittal.

---------------------------------------------------------------------------
C. What is the purpose of the submitted regulation?
Section 25 and the other CCAQR sections submitted on September 1,
2010 are part of DAQEM's overall program intended to control the health
and environmental impacts of air pollution. Specifically, CCAQR Section
25 describes the procedures by which air pollution sources may assert
an affirmative defense for violations that result from excess emissions
due to SSM events. CAA Section 110 describes procedures for States to
develop and submit various air pollution regulations to EPA as part of
SIP revisions. EPA interprets the CAA to authorize a state to elect to
create narrowly drawn affirmative defense provisions applicable to
malfunctions, consistent with EPA guidance. Accordingly, the Section 25
provision submitted by Clark County is not required by the CAA, but may
be submitted to EPA under CAA section 110(a).
D. What does the submitted regulation provide?
CCAQR Section 25 establishes affirmative defenses applicable to
violations that result from excess emissions. Section 25.1 states that
affirmative defenses for certain excess emissions are available in the
case of violations of all emission standards and limitations, except
those specifically listed in Section 25.1.1(a) through (d), which are
primarily emission limits or standards related to federal requirements
under the CAA. For example, EPA interprets the exceptions from
25.1.1(a) to provide that Section 25 does not operate to create any
affirmative defense applicable to violations of any EPA standards
promulgated pursuant to CAA section 111.
Section 25.2 states that emissions in excess of emission limits
that were caused by equipment malfunction constitute a violation.
However, a source is provided an affirmative defense from civil and
administrative enforcement (except injunctive relief) for these
violations if it meets the reporting requirements in Section 25.6 and
demonstrates compliance with Sections 25.2.1(a) through (j), which
require that: (a) The excess emissions resulted from a sudden and
unavoidable equipment breakdown beyond reasonable control; (b)
equipment was well maintained and operated; (c) equipment was repaired
expeditiously; (d) excess emissions were minimized; (e) excess emission
impacts were minimized; (f) there was no recurring pattern of excess
emissions; (g) ambient air quality standards were not exceeded; (h) the
excess emissions could not have been foreseen or avoided; (i) emission
monitoring systems were operated if practicable; and (j) the response
to the excess emissions was documented by contemporaneous records.
Section 25.3 similarly states that emissions in excess of emission
limits that were caused by equipment startup and shutdown constitute a
violation. However, a source is provided an affirmative defense from
civil and administrative enforcement (except injunctive relief) for
these violations if it meets the reporting requirements in Section 25.6
and demonstrates compliance with Sections 25.3.1(a) through (h), which
require that: (a) The excess emissions could not have been prevented
through prudent planning and design; (b) if the excess emissions
resulted from a bypass of control equipment, the bypass was unavoidable
to prevent loss of life, personal injury or severe property damage; (c)
equipment was well maintained and operated; (d) excess emissions were
minimized; (e) excess emission impacts were minimized; (f) ambient air
quality standards were not exceeded; (g) emission monitoring systems
were operated if practicable; and (h) the response to the excess
emissions was documented by contemporaneous records. Section 25.3.2
notes that if excess emissions occur during scheduled startup and
shutdown, then those instances shall be treated as other malfunctions
subject to Section 25.2.
Section 25.4 states that if excess emissions occur due to a
malfunction during scheduled maintenance, then that exceedance will be
treated the same as other malfunctions subject to 25.2.
To obtain an affirmative defense, Section 25.5 requires sources to
demonstrate, through information required by Section 25.6, that all
reasonable measures were implemented to prevent the excess emissions.
Section 25.6 requires air pollution sources to report to DAQEM
regarding emissions in excess of permit limits by: (a) a notification
within 24 hours of learning of the excess emissions; and (b) a report
containing the information required by Section 25.6.3 within 72 hours
of the initial notification. Section 25.6.2 accelerates these reporting
deadlines where emissions pose imminent and substantial danger. Section
25.6.3 specifies that the report must describe the emissions including:
(a) location; (b) magnitude; (c) time and duration; (d) type of
equipment; (e) cause; (f) steps taken to remedy and prevent future
malfunction; (g) steps taken to limit emissions; and (h) steps taken to
comply with applicable permit procedures. In the case of continuing or
recurring excess emissions, Section 25.6.4 states that the notification
requirements in Sections 25.6.1 and 25.6.2 will be satisfied if the
source provides notification after excess emissions are first detected
and includes in the notification an estimate of the time the excess
emissions will continue.

II. EPA's Evaluation Criteria
A. General Framework for State Submittal and EPA Review of SIP
Revisions
Under the principle of cooperative federalism, both states and EPA
have authorities and responsibilities under the CAA with respect to
SIPs. Pursuant to CAA section 109, 42 U.S.C. 7409, EPA promulgates
National Ambient Air Quality Standards (NAAQS) for criteria pollutants,
the attainment and maintenance of which are considered requisite to
protect the public health and welfare. CAA section 107(a) assigns
states the primary responsibility for assuring that the NAAQS are
attained and maintained, and CAA section 110(a)(1), 42 U.S.C.
7410(a)(1), requires states to develop and submit to EPA, SIPs which
provide for NAAQS implementation, maintenance, and enforcement. CAA
section 110(a)(2), 42 U.S.C. 7410(a)(2), requires each SIP to meet the
requirements listed in section 110(a)(2)(A) through (M).
In developing SIPs, states have broad authority to develop the mix
of emission limitations they deem best suited for the particular
situation, but this discretion is not unbridled. Under CAA section
110(k), EPA is required to determine whether or not SIP submissions in
fact meet all applicable requirements of the Act. EPA is authorized to
approve, disapprove, partially approve and partially disapprove, or
conditionally approve each SIP submission, as appropriate. When a SIP
submission does not meet the applicable requirements of the CAA, EPA is
obligated to disapprove it, in whole or in part, as appropriate.
CAA sections 110(l) and 193 impose additional requirements upon EPA
when reviewing a state's proposed SIP revision. CAA section 110(l), 42
U.S.C. 7410(l), provides that EPA may not approve a SIP revision if it
``would interfere with any applicable requirement concerning attainment
and reasonable further progress, or any other applicable requirement of
this chapter.'' In addition, CAA section 193 prohibits SIP revisions
that would affect control measures in effect prior to the 1990 CAA
amendments in any area that is designated nonattainment for any NAAQS,
unless the modification insures equivalent to greater emission
reductions of such air pollutant.
B. Specific Framework for Evaluating SIP Provisions Regarding Excess
Emissions
The general framework summarized above underlies EPA's evaluation
of SIP submissions as they relate to provisions related to excess
emissions. EPA has a longstanding interpretation of the CAA with
respect to the treatment in SIPs of excess emissions during SSM events.
Central to EPA's interpretation are the definitions of ``emission
limitation'' and ``emission standard'' contained in CAA section 302(k),
42 U.S.C. 7602(k), which are defined as limitations that must be met on
a continuous basis. Under CAA section 110(a)(2)(A), 42 U.S.C.
7410(a)(2)(A), each SIP must include enforceable emission limitations
and other control measures as may be necessary or appropriate to meet
applicable CAA requirements. In addition, under CAA section
110(a)(2)(C), 42 U.S.C. 7410(a)(2)(C), each SIP must provide for the
enforcement of the measures described in CAA section 110(a)(2)(A) and
provide for the regulation of sources as necessary to ensure the
attainment and maintenance of the NAAQS and protection of Prevention of
Significant Deterioration (PSD) increments.
While the CAA requires that emission limitations in a SIP must be
met on a ``continuous'' basis, practical realities or circumstances may
create difficulties in meeting a legally required emission limit
continuously 100% of the time. Case law holding that technology-based
standards should account for the practical realities of technology
supports EPA's view that an enforcement program under a SIP that
incorporates some level of flexibility is reasonable and consistent
with the overall intent of the CAA.\3\ While EPA views all excess
emissions as violations of emission limitations or emission standards,
we recognize that, in certain situations, imposition of a civil penalty
for sudden and unavoidable malfunctions caused by circumstances
entirely beyond a source's control may not be appropriate.
---------------------------------------------------------------------------
\3\ See, e.g., Essex Chemical v. Ruckelshaus, 486 F.2d 427, 433
(D.C. Cir. 1973); and Portland Cement Association v. Ruckelshaus,
486 F.2d 375 (D.C. Cir. 1973).
---------------------------------------------------------------------------
In addressing excess emissions due to sudden and unavoidable
malfunctions, EPA has provided guidance on three approaches states may
elect to use: (1) Traditional enforcement discretion; (2) SIP
provisions that address the exercise of enforcement discretion by state
personnel; and (3) SIP provisions that provide a narrowly tailored
affirmative defense to civil penalties. Under the first approach, the
State (or another entity, such as EPA, seeking to enforce a violation
of the SIP) may consider the circumstances surrounding the event in
determining whether to pursue enforcement. Under the second approach,
states may elect to create SIP provisions that provide parameters for
the exercise of enforcement discretion by state personnel, so long as
they do not adversely affect enforcement by EPA or citizens. Under the
third approach, states may elect to create SIP provisions that
establish an affirmative defense that may be raised by the defendant in
the context of an enforcement proceeding for civil penalties (not
injunctive relief), if the defendant has proven that certain criteria
have been met.
Most relevant to this action, EPA interprets the CAA to allow SIP
provisions that provide an affirmative defense, so long as they are
appropriately drawn. EPA has issued guidance specifically concerning
affirmative defense provisions in SIPs.\4\ EPA guidance recommends
criteria that it considers necessary to assure that the affirmative
defense is consistent with CAA requirements for SIP provisions. EPA
believes that narrowly-tailored affirmative defense provisions can
supply flexibility both to ensure that emission limitations are
``continuous'' as required by CAA section 302(k), because any
violations remain subject to a claim for injunctive relief, and to
provide limited relief for penalties for malfunctions that are beyond
the source's control where the source has taken necessary steps to
minimize the likelihood and extent of any such violation. Several
courts have agreed with this approach.\5\ Neither the enforcement
discretion nor the affirmative defense approaches may waive reporting
requirements for the violation. States are not required to employ an
affirmative defense approach, but if they choose to do so,
[[Page 74060]]
EPA will evaluate the state's SIP provisions for consistency with the
Act as interpreted by our policy and guidance, including those
documents listed in section II.C below.
---------------------------------------------------------------------------
\4\ See Memorandum dated September 20, 1999, from Steven A.
Herman, Assistant Administrator for Enforcement and Compliance
Assurance, and Robert Perciasepe, Assistant Administrator for Air
and Radiation, entitled ``State Implementation Plans: Policy
Regarding Excess Emissions During Malfunctions, Startup, and
Shutdown'' (``1999 Policy''), pg. 3 of the Attachment. EPA notes
that at the time of the 1999 SSM Policy, EPA interpreted the CAA to
allow such affirmative defense provisions not only in the case of
malfunctions, but also in the case of startup and shutdown. For the
reasons explained later in this proposal, EPA no longer interprets
the CAA to permit affirmative defense provisions for events other
than malfunctions, because it believes that sources should be
expected to meet applicable emission limits during normal modes of
source operation or for appropriate alternative emission limits to
apply during such normal modes of source operation.
\5\ See, Luminant Generation Co. v. EPA, 714 F.3d 841 (5th Cir.
2013) (upholding the EPA's approval of an affirmative defense
applicable during malfunctions in a SIP submission as a permissible
interpretation of the statute under Chevron step 2 analysis), cert
denied, 187 L. Ed. 2d 45 (October 7, 2013); Mont. Sulphur & Chemical
Co. v. EPA, 666 F.3d 1174 (9th Cir. 2012); and Ariz. Public Service
Co. v. EPA, 562 F.3d 1116, 1130 (9th Cir. 2009).
---------------------------------------------------------------------------
In CCAQR Section 25 as submitted, DAQEM has elected to create an
affirmative defense provision applicable to excess emissions for SSM
events. EPA acknowledges that DAQEM attempted to develop these
affirmative defenses in NDEP's September 1, 2010 SIP submittal
consistent with EPA guidance at that time. However, EPA has reexamined
its interpretation of the CAA with respect to affirmative defenses and
accordingly believes that such affirmative defenses are only
appropriate in the case of unplanned events like malfunctions, not in
the case of planned events such as startup and shutdown for which
sources should be expected to comply with applicable SIP emission
limitations. Under CAA sections 110(k) and 110(l), EPA is obligated to
determine whether SIP submissions in fact meet CAA requirements and our
interpretation of the Act at the time EPA takes action on a SIP
submission.
C. What documents did we use in our evaluation?
EPA's interpretation of the Act as it applies to SIP provisions
that address excess emissions occurring during SSM periods is set forth
in a series of guidance documents. These include: (1) A memorandum
dated September 28, 1982, from Kathleen M. Bennett, Assistant
Administrator for Air, Noise, and Radiation, entitled ``Policy on
Excess Emissions During Startup, Shutdown, Maintenance, and
Malfunctions'' (1982 Policy); (2) a memorandum dated February 15, 1983,
from Kathleen M. Bennett, Assistant Administrator for Air, Noise, and
Radiation, also entitled, ``Policy on Excess Emissions During Startup,
Shutdown, Maintenance, and Malfunctions'' (1983 Policy); (3) a
memorandum dated September 20, 1999, from Steven A. Herman, Assistant
Administrator for Enforcement and Compliance Assurance, and Robert
Perciasepe, Assistant Administrator for Air and Radiation, entitled
``State Implementation Plans: Policy Regarding Excess Emissions During
Malfunctions, Startup, and Shutdown'' (1999 Policy); and (4) a
memorandum dated December 5, 2001, from Eric Schaeffer, Director,
Office of Regulatory Enforcement, Office of Enforcement and Compliance
Assurance, and John S. Seitz, Director, Office of Air Quality Planning
and Standards, Office of Air and Radiation, entitled, ``Re-Issuance of
Clarification--State Implementation Plans (SIPs): Policy Regarding
Excess Emissions During Malfunctions, Startup, and Shutdown'' (2001
Policy).
EPA's interpretation of the CAA with respect to SIP provisions that
address excess emissions during SSM events has been applied in
rulemaking, including, but not limited to: (1) EPA's ``Approval and
Promulgation of Implementation Plans; Texas; Excess Emissions During
Startup, Shutdown, Maintenance, and Malfunction Activities,'' 75 FR
68989 (Nov. 10, 2010); (2) EPA's ``Federal Implementation Plan for the
Billings/Laurel, MT, Sulfur Dioxide Area,'' 73 FR 21418 (Apr. 21,
2008); and (3) EPA's ``Finding of Substantial Inadequacy of
Implementation Plan: Call for Utah State Implementation Plan
Revision,'' April 18, 2011 (76 FR 21639).
In addition, EPA recently issued a proposal in response to a
petition for rulemaking concerning CAA requirements for SIP provisions
that address excess emissions, reiterating EPA's interpretation of the
CAA with respect to such provisions.\6\ In this recent action, EPA
specifically addressed the CAA requirements with respect to SIP
provisions that provide an affirmative defense for violations of
emission limitations due to excess emissions during SSM events.
---------------------------------------------------------------------------

Rulemaking; Findings of Substantial Inadequacy; and SIP Calls To

(``February 22, 2013 Proposed SSM SIP Calls''); see also EPA's
February 4, 2013 Statutory, Regulatory, and Policy Context
Memorandum for the February 22, 2013 Proposed SSM SIP Calls.
---------------------------------------------------------------------------
A copy of each document listed in this section is available in the
docket for this rulemaking.
III. EPA's Evaluation and Action
A. Does the regulation meet the evaluation criteria?
NDEP's September 1, 2010 submission of CCAQR Section 25 fails to
meet the evaluation criteria in at least two significant respects.
First, Sections 25.1 and 25.3 are inconsistent with the
requirements provided in CAA section 110(a) and conflict with the
fundamental enforcement structure provided in CAA sections 113 and 304,
because they create an affirmative defense for violations due to excess
emissions during startup and shutdown. EPA believes that providing
affirmative defenses for avoidable violations, such as those resulting
from excess emissions during planned events such as startups and
shutdowns, that are within the source's control, is inconsistent with
the requirements provided in CAA section 110(a) and the fundamental
enforcement structure provided in CAA sections 113 and 304,\7\ which
provide for potential civil penalties for violations of SIP
requirements.\8\
---------------------------------------------------------------------------
\7\ See, Luminant Generation Co. v. EPA, 714 F.3d 841 (5th Cir.
2013) (upholding the EPA's approval of an affirmative defense
applicable during malfunctions in a SIP submission as a permissible
interpretation of the statute under Chevron step 2 analysis), cert
denied, 187 L. Ed. 2d 45 (October 7, 2013); See also, EPA's February
22, 2013 Proposed SIP Calls (78 FR 12460, 12480).
\8\ See EPA's February 22, 2013 Proposed SIP Calls (78 FR 12460,
12480).
---------------------------------------------------------------------------
By contrast, SIP provisions providing affirmative defenses can be
appropriate for malfunctions because, by definition and unlike planned
startups and shutdowns, malfunctions are unforeseen and could not have
been avoided by the source, and the source will have taken steps to
prevent the violation and to minimize the effects of the violation
after it occurs. In such circumstances, EPA interprets the Act to allow
narrowly drawn affirmative defense provisions that may provide relief
from civil penalties (but not injunctive relief) to sources, when their
conduct justifies this relief.\9\ Such is not the case with planned and
predictable events, such as startups and shutdowns, during which
sources should be expected to comply with applicable SIP emission
limitations and should not be accorded relief from civil penalties if
they fail to do so.\10\ Providing an affirmative defense for monetary
penalties for violations that result from planned events is
inconsistent with the basic premise that the excess emissions were
beyond the source's control, and thus is diametrically opposed to the
intended purpose of such an affirmative defense to encourage better
compliance even by sources for which 100% compliance is not possible.
---------------------------------------------------------------------------
\9\ See EPA's February 22, 2013 Proposed SIP Calls (78 FR 12460,
12478).
\10\ EPA notes that a state can elect to adopt alternative
emission limitations that apply to normal modes of source operation,
such as startup and shutdown, so long as these provisions are
consistent with CAA requirements. EPA's February 22, 2013 Proposed
SSM SIP Calls provides guidance on how such SIP provisions may be
developed to meet CAA requirements.
---------------------------------------------------------------------------
Second, the criteria for obtaining an affirmative defense for
excess emissions during malfunctions in CCAQR Section 25.2 are not
fully consistent with CAA requirements. EPA has guidance making
recommendations for criteria appropriate for affirmative defense
provisions that would be consistent with the CAA. EPA's 1999 Policy and
the February 22, 2013 Proposed SSM SIP Call lay out these criteria.
These are
[[Page 74061]]
guidance recommendations and states do not need to track EPA's
recommended wording verbatim, but states should have SIP provisions
that are consistent with these recommendations in order to assure that
the affirmative defense meets CAA requirements. The affirmative defense
criteria set forth in Section 25.2.1 are not sufficiently consistent
with these recommended criteria for affirmative defense provisions in
SIPs for malfunctions.
Specifically, EPA's guidance notes that affirmative defenses are
``not appropriate for areas and pollutants where a single source or
small group of sources has the potential to cause an exceedance of the
NAAQS or PSD increments.'' \11\ CCAQR Section 25.2.1(g) states that
sources with emissions in excess of an applicable emission limitation
due to a malfunction have an affirmative defense if the source has
demonstrated (among other things) that ``During the period of excess
emissions there were no exceedances of the relevant ambient air quality
standards established in Section 11 that could be attributed to the
emitting source.'' This deviates from EPA's guidance because CCAQR
Section 11.2 was adopted and submitted in 2003 and lists ``relevant
ambient air quality standards'' that do not account for all of the
NAAQS promulgated since the regulation was approved into the SIP in
2004.\12\ As a result, CCAQR Section 25.2 would allow an affirmative
defense for an exceedance of an applicable emission limitation even if
that exceedance violated a NAAQS that is not listed in CCAQR Section
11.2.\13\
---------------------------------------------------------------------------
\11\ See page 3 of the Attachment to EPA's 1999 Policy on SSM
events.
\12\ See CCAQR Section 11.2, ``Ambient Air Quality Standards,''
adopted by CCBC on 10/7/03, submitted by NDEP to EPA on 10/23/03,
and approved by EPA on 9/7/04 (69 FR 54006); 40 CFR 50.4-50.13.
\13\ See, e.g. the 24-hour standard for PM2.5 of 65
[micro]g/m\3\ in CCAQR Section 11.2, which is inconsistent with the
24-hour standard set on October 17, 2006 of 35 [micro]g/m\3\ (71 FR
61144).
---------------------------------------------------------------------------
In addition, Section 25.2.1(g) is not fully consistent with CAA
requirements because it fails to include consideration of the impacts
of excess emissions during a malfunction on the PSD increments. As
noted above, Section 25.2.1(g) only mentions the relevant ambient air
quality standards in Section 11, and Section 11 also does not mention
the PSD increments. SIP requirements are not limited to those specific
requirements for designated nonattainment areas; SIPs must also meet
requirements related to PSD in attainment areas. Similarly, SIP
provisions addressing affirmative defense provisions cannot be limited
exclusively to impacts on nonattainment areas.
B. EPA Recommendations To Improve the Regulation
CCAQR Section 25.6 requires sources to provide information to DAQEM
regarding excess emissions caused by SSM. Such reporting would enable
DAQEM to review, evaluate, and utilize the information as a tool in its
air quality planning and management efforts and help provide for
attainment and maintenance of the NAAQS and other applicable
requirements of the Act. This reporting would also facilitate effective
enforcement, if appropriate. As a result, while it is not appropriate
at this time for EPA to separately approve Section 25.6 as submitted in
context of the overall Section 25, EPA would support a SIP revision
creating such reporting requirements, independent of the problematic
affirmative defense provisions elsewhere in Section 25.
As stated in Section II.B and elsewhere above, EPA interprets the
CAA to allow only narrowly drawn affirmative defense provisions that
are available for events that are entirely beyond a source's control.
Thus, an affirmative defense may be appropriate for events like
malfunctions, which are sudden and unavoidable events that cannot be
foreseen or planned for. The underlying premise for an affirmative
defense provision is that the source is properly designed, operated and
maintained, and could not have taken action to prevent the exceedance.
Because a qualifying source could not have foreseen or prevented the
event, the affirmative defense is available to provide relief from
monetary penalties that could result from an event beyond a source's
control. Therefore, it may be possible for DAQEM to revise Section 25
to provide an affirmative defense for malfunctions consistent with CAA
requirements, as recommended in EPA's SSM Policy.
The legal and factual basis supporting the concept of an
affirmative defense for malfunctions does not support providing an
affirmative defense for normal modes of operation like startup and
shutdown. Such events are planned and predictable. Sources should be
designed, operated, and maintained to comply with applicable emission
limitations during normal and predictable source operation. Because
startup and shutdown periods are part of a source's normal operations,
the same approach to compliance with, and enforcement of, applicable
emission limitations during those periods should apply as otherwise
applies during a source's normal operations. If justified, the state
can develop and submit to EPA for approval as part of the SIP,
alternative emission limitations or control measures that apply during
startup and shutdown, if a source cannot meet the otherwise applicable
emission limitations in the SIP.
However, even if a source is a suitable candidate for alternative
SIP emission limitations during startup and shutdown, that does not
justify the creation of an affirmative defense in the case of excess
emissions during such events. Because these events are planned, EPA
believes that sources should be able to comply with applicable emission
limitations during these periods of time. To provide an affirmative
defense for violations that occur during planned and predictable events
for which sources should have been expected to comply is tantamount to
providing relief from civil penalties for a planned violation.
Accordingly, EPA recommends that NDEP should eliminate the affirmative
defense provisions in Section 25 applicable to startup and shutdown.
C. Proposed Action and Public Comment
As discussed in Section II.B and elsewhere above, affirmative
defense provisions that include periods of normal source operation that
are within a source's control, such as planned startup and shutdown,
are inconsistent with the requirements of CAA section 110(a) and the
enforcement structure provided in CAA sections 113 and 304. Therefore,
the affirmative defense provision for excess emissions during startup
and shutdown created in Sections 25.1, 25.3 and elsewhere in CCAQR
Section 25 do not meet CAA requirements for SIPs. In addition, the
affirmative defense provisions for malfunctions in Section 25.2 do not
fully comply with the CAA as discussed in Section III.A above, and thus
also do not meet CAA requirements.
As authorized in CAA section 110(k)(3), we are proposing to
disapprove CCAQR Section 25 in NDEP's September 1, 2010 SIP submission
because of the deficiencies discussed in section III.A above.
Affirmative defenses for excess emissions and other elements of Section
25 are not required by the Act, and the lack of affirmative defenses
for excess emissions does not make a SIP deficient. Therefore, if this
disapproval is finalized as proposed, there would be no CAA sanction
implications as described in CAA section 179 and 40 CFR 52.31, and no
Federal
[[Page 74062]]
Implementation Plan (FIP) implications as described in CAA section
110(c).
We will accept comments from the public on this proposed
disapproval for the next 30 days.
IV. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review
This proposed action is not a ``significant regulatory action''
subject to review by the Office of Management and Budget (OMB) under
Executive Order (EO) 12866 (58 FR 51735, October 4, 1993) and is
therefore not subject to review under EO 12866 and EO 13563 (76 FR
3821, January 21, 2011).
B. Paperwork Reduction Act
This proposed action does not impose an information collection
burden under the provisions of the Paperwork Reduction Act (44 U.S.C.
3501 et seq.) because this proposed action under CAA section 110 will
not in and of itself create any new information collection burdens but
simply disapproves certain State requirements for inclusion into the
SIP. Burden is defined at 5 CFR 1320.3(b).
C. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA, 5 U.S.C. 601 et seq.)
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.\14\ This proposed SIP disapproval under section 110 and
subchapter I, part D of the CAA will not have a significant impact on a
substantial number of small entities because it will not create any new
requirements but simply disapproves certain State requirements for
inclusion in the SIP. Accordingly, it affords no opportunity for EPA to
fashion for small entities less burdensome compliance or reporting
requirements or timetables or exemptions from all or part of the rule.
Therefore, I certify that this action will not have a significant
economic impact on a substantial number of small entities under the
RFA. Moreover, due to the nature of the Federal-State relationship
under the CAA, preparation of flexibility analysis would constitute
Federal inquiry into the economic reasonableness of State action. The
CAA forbids EPA to base its actions concerning SIPs on such grounds.
Union Electric Co., v. U.S. EPA, 427 U.S. 246, 255-66 (1976); 42 U.S.C.
7410(a)(2).
---------------------------------------------------------------------------
\14\ Small entities include small businesses, small
organizations, and small governmental jurisdictions. For purposes of
assessing the impacts of this notice on small entities, small entity
is defined as: (1) A small business that is a small industrial
entity as defined in the U.S. Small Business Administration (SBA)
size standards (see 13 CFR 121.201); (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;
or (3) a small organization that is any not-for-profit enterprise
that is independently owned and operated and is not dominant in its
field.
---------------------------------------------------------------------------
D. Unfunded Mandates Reform Act
This action contains no Federal mandates under Title II of the
Unfunded Mandates Reform Act of 1995 (UMRA, 2 U.S.C. 1531-1538), for
State, local, or tribal governments or the private sector. EPA has
determined that the proposed disapproval action does not include a
Federal mandate that may result in estimated costs of $100 million or
more to either State, local, or tribal governments in the aggregate, or
to the private sector. This action proposes to disapprove pre-existing
requirements under State or local law, and imposes no new requirements.
Accordingly, no additional costs to State, local or tribal governments,
or to the private sector, result from this action.
E. Executive Order 13132--Federalism
EO 13132, entitled ``Federalism'' (64 FR 43255, August 10, 1999),
requires EPA to develop an accountable process to ensure ``meaningful
and timely input by State and local officials in the development of
regulatory policies that have federalism implications.'' ``Policies
that have federalism implications'' is defined in EO 13132 to include
regulations that 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.''
This proposed action does not have Federalism implications as
specified in EO 13132. 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 EO 13132, because it
merely disapproves certain State requirements for inclusion into the
SIP and does not alter the relationship or the distribution of power
and responsibilities established in the CAA. Thus, EO 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 EO
13175 (65 FR 67249, November 9, 2000). In this action, EPA is not
addressing any tribal implementation plans. This action is limited to
Clark County, Nevada, and the SIP provisions which are the subject of
the proposed action do not apply to sources of emissions located in
Indian country. Thus, EO 13175 does not apply to this action. However,
EPA invites comment on this proposed rule from tribal officials.
G. Executive Order 13045--Protection of Children From Environmental
Health Risks and Safety Risks
EPA interprets EO 13045 (62 FR 19885, April 23, 1997) as applying
only to those regulatory actions that concern health or safety risks,
such that the analysis required under section 5-501 of EO 13045 has the
potential to influence the regulation. This proposed action is not
subject to EO 13045 because it is not an economically significant
regulatory action based on health or safety risks subject to EO 13045.
This proposed action under section 110 and subchapter I, part D of the
CAA will not in and of itself create any new regulations but simply
disapproves certain State requirements for inclusion into the SIP.
H. Executive Order 13211--Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This proposed action is not a ``significant energy action'' as
defined in EO 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. This proposed action under section 110 and subchapter
I, part D of the CAA will not in and of itself create any new
regulations, but simply disapproves certain State requirements for
inclusion into the SIP.
I. National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (``NTTAA''), Public Law 104-113, section 12(d) (15 U.S.C.
272 note) directs EPA to use voluntary consensus standards in its
regulatory activities unless to do so would be inconsistent with
applicable law or otherwise impractical. Voluntary consensus standards
are technical standards (e.g., materials specifications, test methods,
sampling procedures, and business practices) that are developed or
[[Page 74063]]
adopted by voluntary consensus standards bodies. The NTTAA directs EPA
to provide Congress, through OMB, explanations when the Agency decides
not to use available and applicable voluntary consensus standards.
EPA believes that this proposed action is not subject to
requirements of section 12(d) of NTTAA because application of those
requirements would be inconsistent with the CAA. We also note that this
proposed rulemaking does not involve technical standards. Therefore,
EPA is not considering the use of any voluntary consensus standards.
J. Executive Order 12898--Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
EO 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.
EPA lacks the discretionary authority to address environmental
justice in this proposed action. In reviewing SIP submissions, EPA's
role is to approve or disapprove state choices, based on the criteria
of the CAA. Accordingly, this action merely proposes to disapprove
certain State requirements for inclusion into the SIP under section CAA
110 and will not in and of itself create any new requirements.
