Proposed rule.


EPA is proposing to approve a State Implementation Plan (SIP) revision submitted by the Pennsylvania Department of Environmental Protection (PADEP). This revision pertains to the Air Pollution Control portion of the Allegheny County Health Department (ACHD) Rules and Regulations, relating to ACHD's Prevention of Significant Deterioration (PSD) program. Additionally, EPA is proposing to make a determination that the proposed SIP revision will satisfy the Clean Air Act (CAA) infrastructure requirements relating to PSD for the 1997 ozone and particulate matter less than 2.5 micrometers (PM2.5) National Ambient Air Quality Standards (NAAQS) and the 2006 PM2.5 NAAQS. This Action is being taken under the section 110(k) of the CAA.

Throughout this document, whenever “we,” “us,” or “our” is used, we mean EPA. On July 1, 2008, PADEP submitted a revision to its SIP on behalf ACHD. The SIP submittal consists of changes to the ACHD Rules and Regulations, Article XXI, Air Pollution Control, relating to ACHD's PSD program.

I. Background

On December 14, 1983, EPA delegated authority to ACHD to implement and enforce the provisions of Title 40 Code of Federal Regulations (CFR) Part 40 CFR 52.21 on behalf of EPA (see 48 FR 55625, December 14, 1983).

On February 13, 2003, ACHD requested EPA to update and affirm the existing delegation of authority agreement between Allegheny County and EPA based on the representations included in Allegheny County's February 13, 2003 letter to EPA (see 68 FR 14617). On March 18, 2003, EPA formally notified ACHD that as of the publication date of the information notice in the Federal Register (March 26, 2003), pursuant to 40 CFR 52.21(u), ACHD was delegated full authority to implement all portions of the federal PSD program in 40 CFR 52.21. Future additions, revisions, or deletions to 40 CFR 52.21 which are adopted by EPA are automatically incorporated into this delegation of authority agreement. EPA noted that authority is delegated to ACHD for all sources located in Allegheny County subject to review pursuant to the federal PSD program. This includes all source categories listed in 40 CFR 52.21 for each pollutant regulated by the CAA (see 68 FR 14617).

II. Summary of SIP Revision

On July 1, 2008, PADEP submitted ACHD's proposed revision to their portion of the SIP. This SIP submission adds Allegheny County's Prevention of Significant Deterioration (PSD) regulations at Article XXI section 2102.07 entitled, “Prevention of Significant Deterioration,” by incorporating by reference, the federal PSD program at 40 CFR 52.21 in its entirety. In addition, ACHD requests that as their regulation automatically incorporates by reference all future changes to 40 CFR 52.21, that such future changes be automatically incorporated into the SIP.

The SIP revision submitted by ACHD on July 1, 2008 contained a provision in section 2102.07(d) that would relieve a person of the duty to comply with the PSD requirements as promulgated by EPA and incorporated in section 2102.07 if such person was “legally temporarily relieved of the duty to comply.” On May 1, 2012 PADEP submitted a letter notifying EPA that they were withdrawing that portion of the SIP revision.

III. Proposed Action

EPA is proposing to approve ACHD's PSD permitting program by proposing approval of this SIP submission with the exception of the language in section 2102.7 as described above. EPA has determined that this revision is approvable because it conforms to the CAA and implementing regulations. Additionally, EPA is proposing to determine that ACHD has met its obligations pursuant to the PSD portion of the CAA infrastructure requirements of sections 110(a)(2)(C), (D)(i)(II), and (J) for the 1997 ozone and PM2.5 NAAQS and the 2006 PM2.5 NAAQS. Copies of the technical support document supporting EPA's decision to approve ACHD's PSD permitting program and EPA's determination that ACHD has met its obligations pursuant to the PSD portion of the infrastructure requirements of the CAA can be obtained from the docket as discussed in the ADDRESSES section above. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action.

IV. Statutory and Executive Order Reviews

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA 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 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 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 (Public Law 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 U.S.C. 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 SIP revision, regarding Allegheny County's Prevention of Significant Deterioration (PSD) program, 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.
