Download as PDF Federal Register / Vol. 79, No. 136 / Wednesday, July 16, 2014 / Proposed Rules section 110(a)(2)(M) for the 1997 PM2.5, 2006 PM2.5, and 2008 ozone NAAQS. V. Proposed Action We are proposing to approve the Alaska SIP as meeting the following CAA section 110(a)(2) infrastructure elements for the 1997 PM2.5, 2006 PM2.5, and 2008 ozone NAAQS: (A), (B), (C), (D)(ii), (E), (F), (H), (J), (K), (L), and (M). We are also proposing to approve the Alaska SIP as meeting the requirements of CAA section 110(a)(2)(D)(i)(II) as it applies to prevention of significant deterioration and visibility for the 2006 PM2.5 and 2008 ozone NAAQS. In addition, we are proposing to approve the Alaska SIP as meeting the requirements of CAA section 110(a)(2)(G) for the 2008 ozone NAAQS. As discussed above, final action is contingent upon the EPA first taking final action on the May 5, 2014, proposed approval of revisions to the Alaska SIP to reflect changes to the NAAQS and Federal PSD permitting requirements (79 FR 25533). tkelley on DSK3SPTVN1PROD with PROPOSALS VI. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the EPA’s role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this proposed action merely approves the state’s law as meeting Federal requirements and does not impose additional requirements beyond those imposed by the state’s law. For that reason, this proposed action: • Is not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993); • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); • Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); • Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4); • Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); VerDate Mar<15>2010 17:37 Jul 15, 2014 Jkt 232001 • Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); • Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because it does not involve technical standards; and • Does not provide the EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994). In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in Alaska, and the EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.

Background and, in accordance with the definition of ‘‘emission limitations’’ in CAA section 302(k), such emission limitations must be continuous. In addition, under CAA section 304(a), any person may bring a civil action against any person alleged to have violated (if there is evidence that the alleged violation has been repeated) or to be in violation of an ‘‘emission standard or limitation’’ under the CAA. For the purposes of section 304, ‘‘emission standard or limitation’’ is defined in section 304(f) and includes SIP emission limitations. Thus, SIP emissions limitations can be enforced in a section 304 action and so must be capable of enforcement. SIP provisions that create exemptions such that excess emissions during startup, shutdown, malfunctions (SSM) and other conditions are not violations of the applicable emission limitations are inconsistent with these fundamental requirements of the CAA with respect to emission limitations in SIPs. WAQSR Chapter 3, section 2(d) created an exemption for particulate matter emissions in excess of a 30 percent opacity standard from diesel engines during startup, malfunction, and maintenance. Because this provision allowed exemptions from the otherwise applicable SIP emission limit, it was inconsistent with CAA requirements. On June 30, 2011, the Sierra Club filed with the EPA Administrator a petition for rulemaking concerning states’ treatment of excess emissions from sources during SSM events (the Petition).1 In the Petition, the Sierra Club identified existing SIP provisions in 39 states that the Sierra Club considered inconsistent with the CAA, including one provision in the Wyoming SIP. Specifically, the Sierra Club argued that WAQSR Chapter 3, ‘‘General Emission Standards,’’ section 2, ‘‘Emission standards for particulate matter,’’ subsection (d) ‘‘is contrary to EPA policy for source category specific rules for startup and shutdown.’’ 2 On February 22, 2013, EPA published a proposed rulemaking in which (among other things) we proposed to grant the Petition as it pertained to WAQSR Chapter 3, section 2(d). 78 FR 12460, 12533. We concurred with Sierra Club’s assertion that this provision is inconsistent with the requirements of the CAA. For this reason, we proposed to find that WAQSR Chapter 3, section 2(d) is substantially inadequate to meet CAA requirements, and concurrently In accordance with the requirements of CAA section 110(a)(2)(A), SIPs must contain enforceable emission limitations 1 The Petition is available to view in the docket for this action. 2 Id. at 74. I. General Information What should I consider as I prepare my comments for EPA? 1. Submitting Confidential Business Information (CBI). Do not submit this information to EPA through www.regulations.gov or email. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD–ROM that you mail to EPA, mark the outside of the disk or CD–ROM as CBI and then identify electronically within the disk or CD–ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. 2. Tips for Preparing Your Comments. When submitting comments, remember to: • Identify the rulemaking by docket number and other identifying information (subject heading, Federal Register, date, and page number); • Follow directions and organize your comments; • Explain why you agree or disagree; • Suggest alternatives and substitute language for your requested changes; • Describe any assumptions and provide any technical information and/ or data that you used; • If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced; • Provide specific examples to illustrate your concerns, and suggest alternatives; • Explain your views as clearly as possible, avoiding the use of profanity or personal threats; and • Make sure to submit your comments by the comment period deadline identified.

Therefore, we are proposing to approve the removal of this language from the provision.4 Wyoming also added language to WAQSR Chapter 3, section 2(d) clarifying that the provision applies to both stationary and portable diesel engines. EPA finds no issue with this clarifying language and therefore proposes to approve this change as well. III. Wyoming Revisions and EPA Analysis tkelley on DSK3SPTVN1PROD with PROPOSALS proposed to issue a SIP call for this provision. On February 10, 2014, WDEQ submitted to EPA SIP revisions that included the removal of the problematic language in WAQSR Chapter 3, section 2(d), as well as updates to the State’s incorporation by reference (IBR) of federal regulations. The State’s IBR updates will be acted upon in a separate rulemaking. IV. EPA’s Proposed Action We are proposing to approve the revisions to WAQSR Chapter 3, section 2(d) of the Wyoming SIP, as reflected in the State’s February 10, 2014 submission. Under CAA section 107, states have the primary authority and responsibility to develop and implement SIPs that provide for attainment, maintenance, and enforcement of the National Ambient Air Quality Standards and meet other CAA requirements. Pursuant to CAA section 110(k), EPA has the authority and responsibility to review state SIP submissions to assure that they meet all applicable requirements. CAA section 110(l) prohibits EPA from approving a SIP revision that (among other things) would interfere with any applicable requirement of the CAA. In this instance, the State has elected to revise its existing SIP by editing a previously approved provision that created exemptions from otherwise applicable emission limitations in the SIP. The State made two edits to WAQSR Chapter 3, section 2(d). Notably, the sentence that read ‘‘This limitation shall not apply during a reasonable period of warmup following a cold start or where undergoing repairs and adjustment following malfunction’’ was struck from the provision. We consider this change sufficient to correct the provision’s inadequacy and to meet the requirements of the CAA.3 As a result of the removal of the problematic language from WAQSR Chapter 3, section 2(d), the improper exemptions from the emissions limitation contained within this provision will no longer be available to sources. EPA’s proposed approval is also consistent with CAA section 110(l) because approval will not interfere with any applicable requirement of the CAA. Specifically, removal of the exemptions will not relax the existing emission limitation in the SIP and will in fact be more protective. Furthermore, this revision will render the revised emissions limitation consistent with the requirements of the CAA for SIP provisions by making it continuously 3 For a more in-depth discussion on the inadequacy of WAQSR Chapter 3, section 2(d), see our proposed SIP call at 78 FR 12533, February 22, 2013.

II. Background

    In accordance with the requirements of CAA section 110(a)(2)(A), 
SIPs must contain enforceable emission limitations and, in accordance 
with the definition of ``emission limitations'' in CAA section 302(k), 
such emission limitations must be continuous. In addition, under CAA 
section 304(a), any person may bring a civil action against any person 
alleged to have violated (if there is evidence that the alleged 
violation has been repeated) or to be in violation of an ``emission 
standard or limitation'' under the CAA. For the purposes of section 
304, ``emission standard or limitation'' is defined in section 304(f) 
and includes SIP emission limitations. Thus, SIP emissions limitations 
can be enforced in a section 304 action and so must be capable of 
enforcement. SIP provisions that create exemptions such that excess 
emissions during startup, shutdown, malfunctions (SSM) and other 
conditions are not violations of the applicable emission limitations 
are inconsistent with these fundamental requirements of the CAA with 
respect to emission limitations in SIPs.
    WAQSR Chapter 3, section 2(d) created an exemption for particulate 
matter emissions in excess of a 30 percent opacity standard from diesel 
engines during startup, malfunction, and maintenance. Because this 
provision allowed exemptions from the otherwise applicable SIP emission 
limit, it was inconsistent with CAA requirements.
    On June 30, 2011, the Sierra Club filed with the EPA Administrator 
a petition for rulemaking concerning states' treatment of excess 
emissions from sources during SSM events (the Petition).\1\ In the 
Petition, the Sierra Club identified existing SIP provisions in 39 
states that the Sierra Club considered inconsistent with the CAA, 
including one provision in the Wyoming SIP. Specifically, the Sierra 
Club argued that WAQSR Chapter 3, ``General Emission Standards,'' 
section 2, ``Emission standards for particulate matter,'' subsection 
(d) ``is contrary to EPA policy for source category specific rules for 
startup and shutdown.'' \2\

    \1\ The Petition is available to view in the docket for this 
action.
    \2\ Id. at 74.
---------------------------------------------------------------------------

    On February 22, 2013, EPA published a proposed rulemaking in which 
(among other things) we proposed to grant the Petition as it pertained 
to WAQSR Chapter 3, section 2(d). 78 FR 12460, 12533. We concurred with 
Sierra Club's assertion that this provision is inconsistent with the 
requirements of the CAA. For this reason, we proposed to find that 
WAQSR Chapter 3, section 2(d) is substantially inadequate to meet CAA 
requirements, and concurrently

proposed to issue a SIP call for this provision.
    On February 10, 2014, WDEQ submitted to EPA SIP revisions that 
included the removal of the problematic language in WAQSR Chapter 3, 
section 2(d), as well as updates to the State's incorporation by 
reference (IBR) of federal regulations. The State's IBR updates will be 
acted upon in a separate rulemaking.

III. Wyoming Revisions and EPA Analysis

    Under CAA section 107, states have the primary authority and 
responsibility to develop and implement SIPs that provide for 
attainment, maintenance, and enforcement of the National Ambient Air 
Quality Standards and meet other CAA requirements. Pursuant to CAA 
section 110(k), EPA has the authority and responsibility to review 
state SIP submissions to assure that they meet all applicable 
requirements. CAA section 110(l) prohibits EPA from approving a SIP 
revision that (among other things) would interfere with any applicable 
requirement of the CAA. In this instance, the State has elected to 
revise its existing SIP by editing a previously approved provision that 
created exemptions from otherwise applicable emission limitations in 
the SIP.
    The State made two edits to WAQSR Chapter 3, section 2(d). Notably, 
the sentence that read ``This limitation shall not apply during a 
reasonable period of warmup following a cold start or where undergoing 
repairs and adjustment following malfunction'' was struck from the 
provision.
    We consider this change sufficient to correct the provision's 
inadequacy and to meet the requirements of the CAA.\3\ As a result of 
the removal of the problematic language from WAQSR Chapter 3, section 
2(d), the improper exemptions from the emissions limitation contained 
within this provision will no longer be available to sources. EPA's 
proposed approval is also consistent with CAA section 110(l) because 
approval will not interfere with any applicable requirement of the CAA. 
Specifically, removal of the exemptions will not relax the existing 
emission limitation in the SIP and will in fact be more protective. 
Furthermore, this revision will render the revised emissions limitation 
consistent with the requirements of the CAA for SIP provisions by 
making it continuously applicable and more enforceable. Therefore, we 
are proposing to approve the removal of this language from the 
provision.\4\
---------------------------------------------------------------------------

    \3\ For a more in-depth discussion on the inadequacy of WAQSR 
Chapter 3, section 2(d), see our proposed SIP call at 78 FR 12533, 
February 22, 2013.
    \4\ We note that if we finalize our proposed approval of this 
revision to the Wyoming SIP, it will have the effect of mooting our 
proposed SIP call regarding this provision.
---------------------------------------------------------------------------

    Wyoming also added language to WAQSR Chapter 3, section 2(d) 
clarifying that the provision applies to both stationary and portable 
diesel engines. EPA finds no issue with this clarifying language and 
therefore proposes to approve this change as well.

IV. EPA's Proposed Action

    We are proposing to approve the revisions to WAQSR Chapter 3, 
section 2(d) of the Wyoming SIP, as reflected in the State's February 
10, 2014 submission.

V. Statutory and Executive Orders Review

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
proposed action merely proposes to approve state law as meeting federal 
requirements and does not impose additional requirements beyond those 
imposed by state law. For that reason, this proposed action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 USC 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 USC 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999); is not an 
economically significant regulatory action based on health or safety 
risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 USC 272 
note) because application of those requirements would be inconsistent 
with the CAA; and,
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this proposed rule does not have tribal implications 
as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the state, and EPA notes that it will not impose substantial direct 
costs on tribal governments or preempt tribal law.
