Based on our proposed determination that the Provo, UT NAA is currently attaining the 24-hour PM2.5 NAAQS, the EPA is also proposing to determine that the obligation for Utah to make submissions to meet certain Clean Air Act (CAA or the Act) requirements related to attainment of the NAAQS for this area is not applicable for as long as the area continues to attain the NAAQS.
Approval and Promulgation of Air Quality Implementation Plans; Wyoming; Interstate Transport for the 2008 Ozone National Ambient Air Quality Standards
The Environmental Protection Agency (EPA) is proposing action on a submission from the State of Wyoming that is intended to demonstrate that the Wyoming State Implementation Plan (SIP) meets certain interstate transport requirements of the Clean Air Act (Act or CAA) for the 2008 ozone National Ambient Air Quality Standards (NAAQS). This submission addresses interstate transport ``prong 2,'' which requires each state's SIP to prohibit emissions which will interfere with maintenance of the NAAQS in other states. The EPA is proposing to approve this submittal as meeting the requirement that Wyoming's SIP contain adequate provisions to prohibit emissions in amounts which will interfere with maintenance of the 2008 ozone NAAQS in any other state.
Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Commercial Fuel Oil Sulfur Limits for Combustion Units in Allegheny County
The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision submitted by the Commonwealth of Pennsylvania. The revision updates Allegheny County's portion of the Pennsylvania SIP, which includes regulations concerning sulfur content in fuel oil. This revision will implement low sulfur fuel oil provisions that will reduce the amount of sulfur in fuel oils used in combustion units which will aid in reducing sulfates that cause decreased visibility. This revision will strengthen the Pennsylvania SIP. This action is being taken under the Clean Air Act (CAA).
Approval and Promulgation of Air Quality Implementation Plans; Delaware; Revisions to the Regulatory Definition of Volatile Organic Compounds
The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision formally submitted by the State of Delaware. This revision pertains to amendments made to the definition of ``volatile organic compound'' (VOC) in the Delaware Administrative Code to conform with EPA's regulatory definition of VOC. The EPA found that certain compounds have a negligible photochemical reactivity and therefore has exempted them from the regulatory definition of VOC in several rulemaking actions, as discussed below. This revision to the Delaware SIP requested the exemption of these compounds from the regulatory definition of VOC to match the actions EPA has taken. The revision also requested minor changes to the format of some of the chemical formulas for VOCs that are already excluded from the definition of VOC in the Delaware SIP. EPA is approving these revisions to update the definition of VOC in the Delaware SIP under the Clean Air Act (CAA).
Approval and Promulgation of Air Quality Implementation Plans; Maryland; Removal of Stage II Gasoline Vapor Recovery Program Requirements
The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision submitted by the State of Maryland. This revision seeks to remove requirements for gasoline vapor recovery systems installed on gasoline dispensers, the purpose of which are to capture emissions from vehicle refueling operations (otherwise known as Stage II vapor recovery). Specifically, this action would remove from the approved SIP prior approved Stage II requirements applicable to new gasoline dispensing facilities (GDFs) and existing GDF's undergoing major modification. GDF's will have the choice whether to install Stage II at new stations or whether to decommission Stage II at existing stations already equipped with Stage II. Owners that elect to retain existing Stage II equipment can do so, but in doing must continue to test and to maintain or replace existing equipment. Maryland's SIP revision includes a demonstration that removal of Stage II requirements is consistent with the Clean Air Act (CAA) and meets all relevant EPA guidance.
Air Plan Approval; North Carolina; Miscellaneous Rules
The Environmental Protection Agency (EPA) is proposing to approve changes to the North Carolina State Implementation Plan (SIP) submitted by the State of North Carolina, through the North Carolina Department of Environmental Quality (NCDEQ), through letters dated April 4, 2017, August 22, 2017, and September 28, 2018. These SIP revisions make amendments, most of which are structural and minor, to North Carolina's source testing rules. This action is being taken pursuant to the Clean Air Act (CAA or Act).
Air Plan Approval; GA: Non-Interference Demonstration and Maintenance Plan Revision for Federal Low-Reid Vapor Pressure Requirement in the Atlanta Area
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision that would support a change to the Federal Reid Vapor Pressure (RVP) requirements in 13 counties in Atlanta, Georgia. They comprise the following counties: Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding, and Rockdale (the ``Atlanta fuel volatility Area''). The Atlanta fuel volatility Area is a subset of the Atlanta 15-county 2008 8-hour ozone maintenance area. The 15-county 2008 8-hour ozone maintenance area is comprised of the following counties: Bartow, Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Newton, Paulding, and Rockdale (the ``Atlanta maintenance Area''). This proposed approval is based in part on EPA's analysis of whether the SIP revision would interfere with the 15-county Atlanta maintenance Area's ability to meet the requirements of the Clean Air Act (CAA or Act). On August 15, 2018, Georgia through the Georgia Environmental Protection Division (GA EPD), submitted a noninterference demonstration to support its SIP revision requesting that EPA relax the federal RVP requirements for the Atlanta fuel volatility Area. This SIP revision updates Georgia's 2008 8-hour ozone maintenance plan for the 15-county Atlanta maintenance Area and its emissions inventory, the associated motor vehicle emissions budgets (MVEBs) and includes measures to offset the emissions increases expected from the relaxation of the federal RVP requirements. Georgia's noninterference demonstration concludes that relaxing the federal RVP requirement from 7.8 pounds per square inch (psi) to 9.0 psi for gasoline sold between June 1 and September 15 of each year in the Atlanta fuel volatility Area would not interfere with attainment or maintenance of any national ambient air quality standards (NAAQS or standards) or with any other CAA requirement. EPA is proposing to approve this SIP revision because EPA has preliminarily determined that the revision is consistent with the applicable provisions of the CAA.
Clean Air Plans; 2008 8-Hour Ozone Nonattainment Area Requirements; San Joaquin Valley, California
The Environmental Protection Agency (EPA) is taking final action to approve portions of three state implementation plan (SIP) revisions submitted by the State of California to meet Clean Air Act (CAA or ``the Act'') requirements for the 2008 8-hour ozone national ambient air quality standards (NAAQS or ``standards'') in the San Joaquin Valley, California ozone nonattainment area. First, the EPA is approving the portions of the ``2016 Ozone Plan for the 2008 8-Hour Ozone Standard'' (``2016 Ozone Plan'') that address the requirements to demonstrate attainment by the applicable attainment date and implementation of reasonably available control measures, among other requirements. Second, the EPA is approving the portions of the ``Revised Proposed 2016 State Strategy for the State Implementation Plan'' (``2016 State Strategy'') related to the ozone control strategy for the San Joaquin Valley for the 2008 ozone standards, including a specific aggregate emissions reduction commitment. Lastly, the EPA is approving an air district rule addressing the emission statement requirement for ozone nonattainment areas.
