On October 26, 2015, EPA revised the ozone NAAQS from 0.075 parts per million (ppm) to 0.070 ppm,
and subsequently designated the Baltimore, MD, Philadelphia-Wilmington-Atlantic City, PA-NJ-MD-DE, and Washington, DC-MD-VA areas as Marginal Nonattainment for the 2015 ozone NAAQS on June 4, 2018.
These areas include the following Maryland counties: Anne Arundel, Baltimore, Baltimore City, Carroll, Harford, Howard, Cecil, Calvert, Charles, Frederick, Montgomery, and Prince George's counties.
Section 182 of the CAA identifies plan submissions and requirements for ozone nonattainment areas. Specifically, section 182(a)(3)(B) requires that states develop and submit rules which establish annual reporting requirements for certain stationary sources. Sources that are within marginal (or worse) ozone nonattainment areas must annually report the actual emissions of nitrogen oxides (NOX) and volatile organic compounds (VOC) to the state. However, states may waive reporting requirements for sources that emit under 25 tpy of NOX and VOC if the state provides an inventory of emissions from such class or category of sources. See CAA section 182(a)(3)(B)(ii).
Additionally, Maryland is located in the ozone transport region (OTR) Start Printed Page 32007established by Congress in section 184 of the CAA. Pursuant to section 184(b)(2), any stationary source that emits or has the potential to emit at least 50 tons per year (tpy) of VOC shall be considered a major stationary source and subject to the requirements which would be applicable to major stationary sources if the area were classified as a moderate nonattainment area. See CAA section 184. Thus, states within the OTR are subject to certain plan requirements in CAA section 182(b) applicable to moderate nonattainment areas. Also, section 182(f)(1) of the CAA requires that the plan provisions required for major stationary sources of VOC also apply to major stationary sources of NOX for states with moderate (or worse) ozone nonattainment areas. A major stationary source of NOX is defined as a stationary facility or source of air pollutants which directly emits or has the potential to emit 100 tpy or more of NOX. See CAA section 302(j). Because Maryland is in the OTR, stationary sources located in attainment areas in Maryland and which emit above 50 tpy of VOC or 100 tpy of NOX are considered major sources and also subject to the requirements of major stationary sources in moderate (or worse) nonattainment areas, including the emissions statement submission required by CAA section 182(a)(3)(B). See CAA sections 182(f) and 184(b)(2).
On July 6, 2020, the State of Maryland, through the Maryland Department of the Environment (MDE), submitted a SIP revision to satisfy the emissions statement requirement of CAA section 182(a)(3)(B) for the 2015 ozone NAAQS.
II. Summary of SIP Revision and EPA Analysis
On October 12, 1994 (59 FR 51517), EPA first approved Maryland's SIP submittal satisfying CAA section 182(a)(3)(B) and has approved submissions for section 182(a)(3)(B) for each succeeding revision of the ozone NAAQS. Maryland's emissions reporting requirements are codified in Code of Maryland Regulations (COMAR) 26.11.01.05-1 “Emissions Statements.” COMAR 26.11.01.05-1 requires sources that emit above specified thresholds of NOX or VOC to submit an emissions statement to the State. The emissions threshold for reporting varies according to the county in which the source is located. The statement must be submitted by a certified individual who can verify the source's actual emissions.
COMAR 26.11.01.05-1.A(1) requires a person who owns or operates any installation, source, or premises that emits 25 tons or more of NOX or VOC during a calendar year and is located in Baltimore City or the counties of Anne Arundel, Baltimore, Calvert, Carroll, Cecil, Charles, Frederick, Harford, Howard, Kent, Montgomery, Prince George's, or Queen Anne's to submit an emissions statement to the state. These counties are included in various ozone nonattainment areas. See 40 CFR 81.321. Per CAA section 182(a)(3)(B)(ii), states may waive this requirement for sources that emit less than 25 tpy of NOX or VOC if the state provides an inventory of emissions from such class or category of sources as required by CAA sections 172 and 182. Maryland provides emissions inventories for nonattainment areas as required by CAA sections 172(c)(3) and 182(a)(3)(B).
COMAR 26.11.01.05-1 also requires a person who owns or operates any installation, source, or premises that emits 50 tons or more of VOC or 100 tons or more of NOX during a calendar year to submit an emissions statement if they are located in the following counties: Allegany, Caroline, Dorchester, Garrett, St. Mary's, Somerset, Talbot, Washington, Wicomico, or Worcester Counties. These counties are designated attainment/unclassifiable for the 2015 ozone NAAQS but within the OTR; therefore, sources in attainment areas for the 2015 ozone NAAQS that emit 50 tpy or more of VOC or 100 tpy or more of NOX are considered major sources and subject to the requirements for major stationary sources applicable to moderate nonattainment areas. Because the requirements for moderate nonattainment areas include all the requirements for marginal areas, major sources in these areas are also subject to the emission statement submission requirement specified in CAA section 182(a)(3)(B).
In Maryland's July 6, 2020 SIP submittal, Maryland states that the existing COMAR 26.11.01.05-1 “Emissions Statements” continues to satisfy section 182(a)(3)(B) for the 2015 ozone NAAQS because Maryland has not made any changes since EPA's prior approval and COMAR 26.11.01.05-1 meets the CAA requirements for emission statements.
EPA is proposing to find that COMAR 26.11.01.05-1 continues to satisfy CAA section 182(a)(3)(B) because the existing rule is applicable to the entire State of Maryland and requires stationary sources that emit NOX or VOC to submit an emissions statement to the State detailing the sources' emissions. EPA finds that Maryland's emissions thresholds for stationary sources that are required to submit an emissions statement meet CAA requirements in sections 182 (plan submissions and requirements for ozone nonattainment areas) and 184 (OTR requirements).
Therefore, EPA has determined that COMAR 26.11.01.05-1, which is currently in the Maryland SIP, is appropriate to address the emissions statement requirement in section 182(a)(3)(B) and is proposing to approve this SIP revision. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action.
III. Proposed Action
EPA is proposing to approve the May 12, 2020 Maryland SIP revision, submitted on July 6, 2020, certifying that Maryland's existing SIP-approved emissions statement regulation meets the emissions statement requirement of section 182(a)(3)(B) of the CAA for the 2015 ozone NAAQS.
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 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.);Start Printed Page 32008
- 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 rulemaking, which proposes to approve Maryland's certification that Maryland's SIP-approved emissions statement regulation meets the emissions statement requirement of section 182(a)(3)(B) of the CAA, 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.
