On January 24, 2013, MDE submitted a revision to the Maryland SIP.

I. Background

The proposed revision consists of amendments to Regulation .09 under section 26.11.02 of the Code of Maryland Regulations (COMAR). An amendment to COMAR inadvertently widened the universe of sources that are required to obtain a permit to construct under COMAR The previously approved version of COMAR requires that any “National Emission Standards for Hazardous Air Pollutants Source (NESHAP Source) as defined in section . . .” obtain a permit to construct. The definition of NESHAP Source at COMAR was amended and simplified (specifically,, effective March 5, 2012.[1] The revised definition had the unintended consequence of requiring that all sources subject to the NESHAP obtain a permit to construct, even the small emission sources which had previously been exempt under section

The proposed revision to section allows MDE to retain the exemptions for smaller sources as originally intended and already approved in the Maryland SIP. Additionally, Regulations .09A(3) and .09A(4) under section 26.11.02 were revised to clarify that electric generating stations that meet the definitions of New Source Performance Standard (NSPS) sources and NESHAP sources are exempt from MDE permitting requirements only if they receive a Certificate of Public Convenience and Necessity (CPCN) from the Maryland Public Service Commission (PSC).

II. Summary of SIP Revision

COMAR has been revised to specify that NESHAP sources “. . . as defined by COMAR,” are required to obtain a permit to construct. This corrects the unintended consequence of applying MDE permitting requirements to emission sources that would otherwise be exempt. COMAR will continue to require that all sources not explicitly exempt are required to obtain a permit to construct. Additionally, as previously discussed, Regulations .09A(3) and .09A(4) under section 26.11.02 have been revised to clarify that electric generating stations that meet the definitions of NSPS sources and NESHAP sources are exempt from permitting requirements only if they receive a CPCN from the Maryland PSC. The proposed revisions were effective in Maryland on July 8, 2013.

III. Proposed Action

EPA's review of this material indicates that it meets all applicable CAA requirements. EPA notes that in a February 10, 2012 final rulemaking action, limited approval was granted to a Maryland SIP revision that included amendments to COMAR See 77 FR 6963. The reasons for that limited approval are unrelated to this action, and do not prevent EPA from granting full approval to the currently proposed amendments to section Start Printed Page 2375726.11.02.09. Therefore, EPA is proposing to approve MDE's January 24, 2013 SIP revision. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action.

IV. Incorporation by Reference

In this proposed rulemaking action, EPA is proposing to include in a final EPA rule, regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by reference Maryland's permit to construct requirements as discussed in section II of this preamble. The EPA has made, and will continue to make, these documents generally available electronically through and/or in hard copy at the appropriate EPA office (see the ADDRESSES section of this preamble for more information).

V. 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 approves 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 (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 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 rule, relating to Maryland's preconstruction permitting requirements, 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.
