Air Plan Approval and Approval of Operating Permits Program; Nebraska; Adoption of the 2015 Ozone Standard and Revisions to Definitions
The Environmental Protection Agency (EPA) is proposing approval of revisions to the State Implementation Plan (SIP), and Operating Permits Program for the State of Nebraska as submitted on August 22, 2018. This action proposes to adopt the 2015 primary and secondary National Ambient Air Quality Standards for Ozone, published in the Federal Register on October 26, 2015. The EPA is also proposing to approve revisions which are administrative in nature. These revisions include updating a reference to EPA's regulation used in the definition of ``Global Warming Potentials'', removing ``Greenhouse Gases'' from the definition of ``Regulated Air Pollutant'', and updating a reference to EPA's regulations used in the definition of ``Volatile Organic Compound''. Other typographical and reformatting revisions are also being made. Approval of these revisions will not impact air quality, ensures consistency between the State and Federally-approved rules, and ensures Federal enforceability of the State's rules.
Air Plan Approval; Massachusetts; Infrastructure State Implementation Plan Requirements for the 2012 PM2.5
The Environmental Protection Agency (EPA) is proposing to approve most elements of a State Implementation Plan (SIP) revision submitted by the Commonwealth of Massachusetts for the infrastructure requirements for the 2012 fine particle (PM2.5) National Ambient Air Quality Standard (NAAQS), including the interstate transport requirements. We are proposing findings of failure to submit for the prevention of significant deterioration (PSD) requirements of infrastructure SIPs for the 2012 PM2.5 NAAQS. We are also proposing several actions related to infrastructure SIP requirements for the 1997 and 2006 PM2.5 NAAQS, including approvals for previously unaddressed elements and converting certain previous conditional approvals to full approval. We are also proposing to convert to full approvals previous conditional approvals for the 1997 and 2008 ozone, 2008 lead, 2010 sulfur dioxide, and 2010 nitrogen dioxide NAAQS. Finally, EPA is proposing to approve five new or amended definitions regarding the NAAQS and Particulate Matter and a state Executive Order regarding consultation by state agencies with local governments. This action is being taken under the Clean Air Act.
Air Plan Approval; OR: Lane County Outdoor Burning and Enforcement Procedure Rules
The Environmental Protection Agency (EPA) is approving and incorporating by reference into the Oregon State Implementation Plan (SIP) the Lane Regional Air Protection Agency's (LRAPA) revised outdoor burning rule submitted by the Oregon Department of Environmental Quality (ODEQ) on July 19, 2018. The revised rule, as it applies in Lane County, Oregon, clarifies terminology and provides additional controls of outdoor burning activities, reducing particulate emissions and strengthening the Oregon SIP. In addition, the EPA is approving but not incorporating by reference the enforcement procedures and civil penalties rule for LRAPA submitted by the ODEQ on September 25, 2018. The revised rule brings the enforcement procedures and civil penalties rule, as it applies in Lane County, into alignment with recent changes in Oregon State regulations.
Approval and Promulgation of Air Quality Implementation Plans; Maryland; Reasonably Available Control Technology (RACT) State Implementation Plan (SIP) Under the 2008 Ozone National Ambient Air Quality Standard (NAAQS)
The Environmental Protection Agency (EPA) is approving a revision to the State of Maryland's state implementation plan (SIP). The State of Maryland's SIP revision satisfies the volatile organic compound (VOC) reasonably available control technology (RACT) requirements for the 2008 8-hour ozone national ambient air quality standard (NAAQS). The State of Maryland will address RACT for oxides of nitrogen (NOX) in another SIP submission. Maryland's VOC RACT submittal for the 2008 ozone NAAQS includes certification that previously adopted RACT controls in Maryland's SIP approved by EPA under the 1-hour ozone and 1997 8-hour ozone NAAQS were reviewed based on the currently available technically and economically feasible controls, and that they continue to represent RACT; a negative declaration for certain control technique guideline (CTG) categories that no facilities exist in the State for these certain categories; and adoption of new or more stringent RACT determinations where necessary. This action is being taken under the Clean Air Act (CAA).
