AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve a revision to the Maryland state implementation plan (SIP). Maryland has submitted for inclusion in the SIP a Consent Agreement between Maryland and Raven Power concerning an inter-facility averaging plan for emissions of nitrogen oxides (NOX) at facilities located in Maryland and owned by Raven Power. The Consent Agreement allows Raven Power to use system-wide emissions averaging to comply with the applicable NOX emission limits for six units located at two electric generating facilities, Brandon Shores and H.A. Wagner, owned by Raven Power. EPA is proposing to approve this revision in accordance with the requirements of the Clean Air Act (CAA).

SUPPLEMENTARY INFORMATION:

I. Background

Maryland's COMAR 26.11.09.08—Control of NOX Emissions for Major Stationary Sources—was approved into Maryland's SIP pursuant to section 182 of the CAA. This regulation established NOX emission limits for the 1-hour ozone national ambient air quality standard (NAAQS) for specific types of boilers and other fuel-burning equipment. Specifically, COMAR 26.11.09.08.C(2) established maximum NOX emission rates as pounds (lbs) of NOX per million British thermal units (MMBtu) per hour, ranging from 0.45 lbs/MMBtu to 0.80 lbs/MMBtu, depending on the type of combustion unit. COMAR 26.11.09.08 also contains a provision that allows an owner or operator of more than one unit to demonstrate compliance with system-wide emissions standards through the use of an averaging plan.

II. Summary of SIP Revision

On July 28, 2016, the State of Maryland through the Maryland Department of the Environment (MDE) submitted to EPA a SIP revision submittal consisting of a Consent Agreement between MDE and Raven Power establishing an inter-facility averaging plan for NOX emissions at two electric generating facilities, Brandon Shores and H.A. Wagner, collectively called Fort Smallwood. Both facilities are owned by Raven Power. MDE requests that this new Consent Agreement and NOX averaging plan replace the Consent Order and NOX averaging plan previously approved into the Maryland SIP on February 27, 2002 (67 FR 8897).

The Consent Agreement between MDE and Raven Power allows Raven Power to use system-wide emissions averaging to comply with the applicable NOX limits for six boiler units (Brandon Shores units 1 and 2 and H.A. Wagner units 1 through 4) subject to COMAR 26.11.09.08. Pursuant to the new Consent Agreement, Raven Power is required to calculate mass emissions from the affected units on a daily basis, determine compliance with the averaging plan using continuous emissions monitors (CEMs), and to submit quarterly reports to both MDE and EPA. In the Consent Agreement, Raven Power agreed that if it fails to comply with the NOX averaging plan, all sources at Brandon Shores and Wagner remain subject to the unit-specific emission limits of COMAR 26.11.09.08.C (shown in Table 1) and must demonstrate compliance through the requirements found in COMAR 26.11.09.08.B(2). The aggregate mass emissions from all units at Brandon Shores and Wagner, under the NOX averaging plan, must be less than the mass emissions that would otherwise occur if each unit were subject to the applicable NOX emissions limit of COMAR 26.11.09.08.C.

Additionally, according to the Consent Agreement, Raven Power must submit a written report and certify annually that the annual NOX mass emissions for all six affected units are at least twenty percent less than otherwise allowed from the affected units by the applicable NOX emission limits of COMAR 26.11.09.08. A more detailed description of the NOX averaging plan can be found in the technical support document (TSD) on www.regulations.gov under Docket ID No. EPA-R03-OAR-2016-0562. In addition, in the July 28, 2016 SIP submittal, Maryland seeks to remove from the Maryland SIP the April 2001 Consent Order between Maryland and Constellation Power Source Generation (Constellation) which functioned as a NOX averaging plan for compliance with COMAR 26.11.09.08 for ten units at five facilities—Brandon Shores units 1 and 2; C.P. Crane units 1 and 2; H.A. Wagner units 1 through 4; Gould Street unit 3; and Riverside unit 4. EPA had approved the April 2001 Consent Order between Maryland and Constellation into the Maryland SIP on February 27, 2002 (67 FR 8897). The 2001 NOX averaging plan is no longer effective for compliance with COMAR 26.11.09.08 as Constellation is not the owner of all of these units and COMAR 26.11.09.08 permitted system-wide averaging only when the same person owned or operated all affected units. COMAR 26.11.09.08.B(4)(a).

III. Proposed Action

EPA has evaluated Maryland's SIP revision submittal and believes Raven Power's NOX emissions averaging plan meets all the applicable requirements of the SIP-approved COMAR 26.11.09.08, particularly subsection .08B(4) for emissions averaging. The Consent Agreement also includes appropriate provisions for monitoring, recordkeeping, and reporting as well as assuring compliance and enforceability. As discussed in the TSD in more detail, EPA expects the Consent Agreement will strengthen the Maryland SIP and lead to additional NOX emission reductions. Thus, the SIP is approvable under CAA section 110.

In addition, EPA finds that this SIP revision submittal meets the requirements of CAA section 110(l) as it will not interfere with attainment and maintenance of any NAAQS, reasonable further progress, or any other applicable CAA requirement, because the NOX averaging plan requires that annual system-wide NOX mass emissions from Brandon Shores and Wagner be at least twenty percent less than otherwise allowed from these affected units by the applicable NOX emission limits of COMAR 26.11.09.08 and because the prior NOX emissions averaging plan that included Brandon Shores, Wagner, and other unrelated units is no longer effective, since the owners have changed. The previously approved April 2001 Constellation NOX averaging plan required that annual system-wide NOX mass emissions be at least five percent less than otherwise allowed by the applicable NOX emission limits of COMAR 26.11.09.08. The system-wide averaging from the new NOX averaging plan which requires at least a twenty percent reduction compared to rates applicable to individual emitting units should provide additional NOX emission reductions. EPA believes the emission reductions from this NOX averaging plan will be beneficial to both Maryland and the ozone transport region (OTR). Therefore, EPA is proposing to approve this SIP revision in accordance with requirements in CAA section 110. EPA is soliciting public comments on the issues discussed in this document and these comments will be considered before taking final action.

IV. Incorporation by Reference

In this proposed rule, 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, EPA is proposing to incorporate by reference Maryland's Consent Agreement with Raven Power concerning a NOX averaging plan discussed in section II of this document as well as in the TSD supporting this rulemaking action. EPA has made, and will continue to make, these materials generally available through http://www.regulations.gov and/or at the EPA Region III Office (please contact the person identified in the For Further Information Contact 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 Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
  • 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 concerning Maryland's NOX averaging plan Consent Agreement with Raven Power 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.
