Environmental Protection Agency (EPA).
Direct final rule.
The Environmental Protection Agency (EPA) is taking direct final action to approve the 2011 base year inventory for the Maryland portion of the Philadelphia-Wilmington-Atlantic City marginal nonattainment area for the 2008 8-hour ozone national ambient air quality standard (NAAQS). The State of Maryland submitted the emission inventory, which included the ozone precursors, nitrogen oxides (NOX) and volatile organic compounds (VOC), as well as several other pollutants, through the Maryland Department of the Environment (MDE) to meet the nonattainment requirements for marginal ozone nonattainment areas for the 2008 8-hour ozone NAAQS. EPA is approving the 2011 base year emissions inventory for the 2008 8-hour ozone NAAQS as a revision to the Maryland State Implementation Plan (SIP) as the inventory for NOX and VOC is in accordance with the requirements of the Clean Air Act (CAA).
This rule is effective on November 24, 2017 without further notice, unless EPA receives adverse written comment by October 25, 2017. If EPA receives such comments, it will publish a timely withdrawal of the direct final rule in the Federal Register and inform the public that the rule will not take effect.

Ground level ozone is formed when NOX and VOC react in the presence of sunlight. NOX and VOC are referred to as ozone precursors and are emitted by many types of pollution sources, including motor vehicles, power plants, industrial facilities, and area wide sources, such as consumer products and lawn and garden equipment. Scientific evidence indicates that adverse public health effects occur following exposure to ozone. These effects are more pronounced in children and adults with lung disease. Breathing air containing ozone can reduce lung function and inflame airways, which can increase respiratory symptoms and aggravate asthma or other lung diseases. In response to this scientific evidence, EPA promulgated the first ozone NAAQS in 1979, the 0.12 part per million (ppm) 1-hour ozone NAAQS. See 44 FR 8202 (February 8, 1979). EPA had previously promulgated a NAAQS for total photochemical oxidants.
On July 18, 1997, EPA promulgated a revised ozone NAAQS of 0.08 ppm, averaged over eight hours. 62 FR 38855. This 8-hour ozone NAAQS was determined to be more protective of public health than the previous 1979 1-hour ozone NAAQS. In 2008, EPA revised the 8-hour ozone NAAQS from 0.08 to 0.075 ppm. See 73 FR 16436 (March 27, 2008).
On May 21, 2012, the Philadelphia-Wilmington-Atlantic City area was designated as marginal nonattainment for the 2008 8-hour ozone NAAQS. 77 FR 30088. The designation of the Philadelphia-Wilmington-Atlantic City area as marginal nonattainment was effective July 20, 2012. The Philadelphia-Wilmington-Atlantic City nonattainment area is comprised of Cecil County in Maryland, as well as counties in Delaware, New Jersey, and Pennsylvania. Under section 172(c)(3) of the CAA, Maryland is required to submit a comprehensive, accurate, and current inventory of actual emissions from all sources of the relevant pollutants, i.e. the ozone precursors NOX and VOC, in its marginal nonattainment area, i.e., the Maryland portion of the Philadelphia-Wilmington-Atlantic City nonattainment area.
II. Summary of SIP Revision and EPA Analysis
Under CAA section 172(c)(3), states are required to submit a comprehensive, accurate, and current inventory of actual emissions from all sources (point, nonpoint, nonroad, and onroad) of the relevant pollutant or pollutants in the nonattainment area. CAA section 182(a)(1) requires that areas designated as nonattainment and classified as marginal submit an inventory of all sources of ozone precursors no later than 2 years after the effective date of designation. EPA's guidance for emissions inventory development calls for actual emissions to be used in the base year inventory. The state must report annual emissions as well as “summer day emissions.” As defined in 40 CFR 51.900(v), “summer day emissions” means, “an average day's emissions for a typical summer work weekday. The state will select the particular month(s) in summer and the day(s) in the work week to be represented.”
On January 19, 2017, MDE submitted a formal revision (SIP #16-15) to its SIP. The SIP revision consists of the 2011 base year inventory for the Maryland portion of the Philadelphia-Wilmington-Atlantic City nonattainment area for the 2008 8-hour ozone NAAQS. MDE selected 2011 as its base year for SIP planning purposes, as recommended in EPA's final rule, “Implementation of the 2008 National Ambient Air Quality Standards for Ozone: State Implementation Plan Requirements.” See 80 FR 12263 (March 6, 2015). MDE's 2011 base year inventory includes emissions estimates covering the general source categories of stationary point, area (nonpoint), nonroad mobile, onroad mobile, and Marine-Air-Rail (M-A-R). Start Printed Page 44523In its 2011 base year inventory, MDE reported actual annual emissions and typical summer day emissions for the months of May through September for NOX, VOC, and carbon monoxide (CO). Although MDE also reported annual emissions for fine particulate matter (PM2.5), sulfur dioxide (SO2), and ammonia (NH3) and typical summer day emissions for CO, in this approval of the 2011 base year emissions inventory for the 2008 ozone NAAQS, EPA is approving only relevant ozone precursors, which are VOC and NOX.
Table 1 summarizes the 2011 VOC and NOX emission inventory by source sector for Maryland's marginal nonattainment area. Annual emissions are given in tons per year (tpy) and summer weekday emissions are given by tons per day (tpd).
Table 1—Summary of 2011 Emissions of Ozone Precursors for the Philadelphia-Wilmington-Atlantic City Nonattainment Area
|Source sector||Summer weekday (tpd)||Annual (tpy)|
Point sources are large, stationary, and identifiable sources of emissions that release pollutants into the atmosphere. Maryland obtained its point source data from the MDE Air and Radiation Management Administration (ARMA) point source emissions inventory. ARMA identifies and inventories stationary sources for the point source emissions inventory through inspections, investigations, permitting, and equipment registrations.
Area sources, also known as nonpoint sources, are sources of pollution that are small and numerous and have not been inventoried as specific point or mobile sources. To inventory these sources, they are grouped so that emissions can be estimated collectively using one methodology. Examples include residential heating emissions and emissions from consumer solvents. MDE calculated nonpoint emissions for the Maryland portion of the Philadelphia-Wilmington-Atlantic City nonattainment area by multiplying emissions factors specific for each source category with some known indicator of collective activity for each source category, such as population or employment data.
Nonroad sources are mobile sources other than onroad vehicles, including aircraft, locomotives, construction and agricultural equipment, and marine vessels. Emissions from different source categories are calculated using various methodologies. MDE relied on EPA's nonroad emissions calculations from the National Mobile Inventory Model (NMIM—April 5, 2009). Onroad or highway sources are vehicles, such as cars, trucks, and buses, which are operated on public roadways. MDE estimated onroad emissions using EPA's Motor Vehicle Emission Simulator (MOVES) model, version 2010a, and appropriate activity levels, such as vehicle miles traveled (VMT) estimates developed from vehicle count data maintained by the State Highway Administration (SHA) of the Maryland Department of Transportation (MDOT). M-A-R sources include marine vessels, airports, and railroad locomotives. MDE estimated M-A-R emissions using data from surveyed sources or state and federal reporting agencies.
EPA reviewed Maryland's 2011 base year emission inventory's results, procedures, and methodologies for the Maryland portion of the Philadelphia-Wilmington-Atlantic City nonattainment area and found them to be acceptable and approvable for sections 110, 172(c)(3) and 182(a)(1) of the CAA. EPA's review and analysis is detailed in a Technical Support Document (TSD) prepared for this rulemaking. The TSD is available online at http://www.regulations.gov, Docket ID No. EPA-R03-OAR-2017-0149.
III. Final Action
EPA is approving the Maryland January 19, 2017 SIP revision as meeting requirements for a base year inventory for the 2008 8-hour ozone NAAQS for the Maryland portion of the Philadelphia-Wilmington-Atlantic City nonattainment area because the inventory for ozone precursors was prepared in accordance with requirements in sections 110, 172(c)(3) and 182(a)(1) of the CAA and its implementing regulations including 40 CFR 51.915. EPA is publishing this rule without prior proposal because EPA views this as a noncontroversial amendment and anticipates no adverse comment. However, in the “Proposed Rules” section of this Federal Register, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision if adverse comments are filed. This rule will be effective on November 24, 2017 without further notice unless EPA receives adverse comment by October 25, 2017. If EPA receives adverse comment, EPA will publish a timely withdrawal in the Federal Register informing the public that the rule will not take effect. EPA will address all public comments in a subsequent final rule based on the Start Printed Page 44524proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting must do so at this time.
IV. Statutory and Executive Order Reviews
A. General Requirements
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 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 rule 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.
B. Submission to Congress and the Comptroller General
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).
C. Petitions for Judicial Review
Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by November 24, 2017. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. Parties with objections to this direct final rule are encouraged to file a comment in response to the parallel notice of proposed rulemaking for this action published in the proposed rules section of this Federal Register, rather than file an immediate petition for judicial review of this direct final rule, so that EPA can withdraw this direct final rule and address the comment in the proposed rulemaking action.
This action approving Maryland's 2011 base year inventory for the 2008 8-hour ozone NAAQS for the Maryland portion of the Philadelphia-Wilmington-Atlantic City nonattainment area may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
