Abstract
The Environmental Protection Agency (EPA) is approving requests for redesignation to attainment status as well as state implementation plan (SIP) revisions submitted by the Commonwealth of Pennsylvania. On January 23, 2019 and February 11, 2019, respectively, the Pennsylvania Department of Environmental Protection (PADEP) submitted requests for EPA to redesignate the Delaware County and Lebanon County nonattainment areas (the Delaware and Lebanon Areas or the Areas) to attainment of the 2012 annual fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS). EPA is granting PADEP's requests and determining that the Delaware and Lebanon Areas meet the 2012 annual PM<INF>2.5</INF> NAAQS, based on the most recent three years of certified air quality data. The effect of this action is to change the designation status of the Delaware and Lebanon Areas from nonattainment to attainment for the 2012 annual PM<INF>2.5</INF> NAAQS, thereby removing the requirement for a nonattainment new source review (NNSR) permitting program and stopping the sanctions clock associated with a finding of failure to submit NNSR updates for the 2012 annual PM<INF>2.5</INF> NAAQS. EPA is also approving PADEP's plans to ensure that the Delaware and Lebanon Areas continue to meet the 2012 PM<INF>2.5</INF> NAAQS through 2030 (maintenance plans) as revisions to the Pennsylvania SIP. The maintenance plans for the Delaware and Lebanon Areas include 2014, 2022, and 2030 motor vehicle emissions budgets (MVEBs) for mobile sources of PM<INF>2.5</INF> and nitrogen oxides (NO<INF>X</INF>). Finally, EPA is finding these 2014, 2022, and 2030 MVEBs for PM<INF>2.5</INF> and NO<INF>X</INF> adequate and is approving these MVEBs into the Pennsylvania SIP for transportation conformity purposes. This action is being taken under the Clean Air Act (CAA).
