Air Plan Approval; California; Antelope Valley Air Quality Management District; Optional General SIP Category
The Environmental Protection Agency (EPA) is proposing to approve a revision to the Antelope Valley Air Quality Management District (AVAQMD) portion of the California State Implementation Plan (SIP). This revision concerns emissions of volatile organic compounds (VOCs) from organic liquid loading. We are proposing to approve revisions to a local rule to regulate these emission sources under the Clean Air Act (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action.
Air Plan Approval; Alabama; Regional Haze Progress Report
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Alabama through the Alabama Department of Environmental Management (ADEM) with a letter dated June 26, 2018. Alabama's SIP revision (Progress Report) addresses requirements of the Clean Air Act (CAA or Act) and EPA's rules that require each state to submit periodic reports describing progress towards reasonable progress goals (RPGs) established for regional haze and a determination of the adequacy of the State's existing SIP addressing regional haze (regional haze plan). EPA is proposing to approve Alabama's determination that the State's regional haze plan is adequate to meet these RPGs for the first implementation period covering through 2018 and requires no substantive revision at this time.
Approval and Promulgation of Air Quality State Implementation Plans; California; Plumas County; Moderate Area Plan for the 2012 PM2.5
The Environmental Protection Agency (EPA) is proposing to approve most elements of the state implementation plan (SIP) revisions submitted by California to address Clean Air Act (CAA or ``Act'') requirements for the 2012 annual fine particulate matter (PM2.5) national ambient air quality standards (NAAQS or ``standards'') in the Plumas County Moderate PM2.5 nonattainment area (``Portola nonattainment area''). The SIP revisions are the ``Portola Fine Particulate Matter (PM2.5) Attainment Plan'' submitted on February 28, 2017, and the 2019 and 2022 transportation conformity motor vehicle emission budgets (``budgets'') submitted on December 20, 2017. We refer to these submittals collectively as the ``Portola PM2.5 Plan'' or ``Plan.'' The EPA is proposing to approve the following elements of the Portola PM2.5 Plan: The 2013 base year emissions inventories, the reasonably available control measure/reasonably available control technology (RACM/RACT) demonstration, the attainment demonstration, the reasonable further progress (RFP) demonstration, the quantitative milestones, and the budgets for 2019 and 2021. The EPA is not proposing any action at this time on the contingency measures in the Portola PM2.5 Plan.
Air Plan Approval; MS; PSD Infrastructure Plan for the 2012 PM2.5
The Environmental Protection Agency (EPA) is approving portions of the State Implementation Plan (SIP) submission, submitted by the State of Mississippi, through the Mississippi Department of Environmental Quality (MDEQ), on December 11, 2015, to demonstrate that the State meets the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2012 annual fine particulate matter (PM2.5) national ambient air quality standard (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an ``infrastructure'' SIP. Specifically, EPA is approving the portions of the submission that relate to the prevention of significant deterioration (PSD) requirements. All other applicable infrastructure requirements for the 2012 Annual PM2.5 NAAQS have been addressed in separate rulemakings.
