Certain other material, such as copyrighted material, is not placed on the Internet and will be publicly available only in hard copy form. Publicly available docket materials are available either electronically in www.regulations.gov or in hard copy during normal business hours at the Air Protection Division, U.S. Environmental Protection Agency, Region III, 1650 Arch Street, Philadelphia, Pennsylvania 19103.

SUPPLEMENTARY INFORMATION:

I. Background

Biomass materials, which include wood residue and wood products, animal manure (including litter and other bedding materials), vegetative agricultural materials as well as silvicultural materials, can be used as fuel burned to provide heat and power. New technologies and environmental initiatives have recently increased the use of biomass material for combustion in the State of Maryland. Therefore, the Maryland Department of the Environment (MDE) has established emission standards for the combustion of biomass fuel by developing a new Code of Maryland (COMAR) regulation, COMAR 26.11.09.12—“Standards for Biomass Fuel-Burning Equipment Greater Than 350,000 British Thermal Units (Btu)/Hour (hr) Heat Input.” The Start Printed Page 15710typical type of equipment that is regulated under this new regulation is a boiler; however, it also applies to process heaters and other applications.

II. Summary of SIP Revision

On January 12, 2015, MDE submitted to EPA a SIP revision concerning new regulation COMAR 26.11.09.12 (Standards for Biomass Fuel-Burning Equipment Equal to or Greater Than 350,000 Btu/hr) and related amendments to regulations .01, .04, .06, .07, .09, and .10 under COMAR 26.11.09—Control of Fuel-Burning Equipment, Stationary Internal Combustion Engines, and Certain Fuel-Burning Installations. The new regulation, COMAR 26.11.09.12, Standards for Biomass Fuel-Burning Equipment Equal to or Greater Than 350,000 Btu/hr, establishes particulate matter (PM) and nitrogen oxide (NOX) emission limits (see Table 1) and additional requirements (such as compliance and record keeping and reporting) for biomass fuel-burning equipment. According to MDE, small biomass boilers will need to install PM emission controls; however, MDE asserts the NOX emission rates for biomass fuel-burning equipment can be achieved through efficient system design and do not require add-on pollution controls. MDE also asserted in the SIP submittal that new biomass fuel-burning equipment would still be subject to standards based on federal maximum achievable control technology (MACT), generally available control technology (GACT), and best available control technology (BACT) analysis. Further EPA analysis and information on the MDE regulations for this SIP submittal are provided in the Technical Support Document (TSD) with Docket ID No. EPA-R03-OAR-2015-0089.

Table 1—Emission Standards for Biomass Fuel-Burning Equipment

Heat input capacity (mmBtu/hr)PM (pounds/mmBtu)NOX (pounds/mmBtu)
≥100.03-0.070.25-0.30
>1.5 and <100.1-0.230.30
>0.35 and ≤1.50.1-0.350.30

MDE has submitted the new biomass fuel-burning provisions in COMAR 26.11.09.12 and revised provisions in COMAR 26.11.09.10 for inclusion in the Maryland SIP. The SIP submittal also includes revisions to COMAR 26.11.09.01 (February 22, 2011, 76 FR 9650), .04 (November 3, 1992, 57 FR 49651), .06 (July 6, 2005, 70 FR 38774), .07 (November 3, 1992, 57 FR 49651), and .09 (May 1, 2003, 68 FR 23206), which were previously included in the Maryland SIP.

III. Proposed Action

EPA's review of this material indicates that MDE's regulation provides emission limits on smaller biomass fuel-burning equipment providing PM and NOX emission reductions which will strengthen the Maryland SIP. The reductions in PM and NOX will help Maryland attain and maintain the National Ambient Air Quality Standards (NAAQS) for ozone and PM. EPA is proposing to approve Maryland's January 12, 2015 SIP revision for biomass fuel-burning equipment. 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 rulemaking, the 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 the Maryland rules regarding the definitions and requirements for biomass fuel-burning equipment in COMAR 26.11.09.01, .04, .06, .07, .09, .10, and .12. The EPA has made, and will continue to make, these documents generally available electronically through www.regulations.gov and/or in hard copy at the EPA Region III 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 pertaining to Maryland's biomass fuel-burning equipment standards 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.
