Abstract
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Massachusetts. On February 9, 2018, the Massachusetts Department of Environmental Protection (MassDEP) submitted revisions to the EPA satisfying the MassDEP's earlier commitment to adopt and submit provisions that meet certain requirements of the Nonattainment New Source Review (NNSR) air permit program regulations. The EPA is also approving the Commonwealth's NNSR certification, which was included in the February 9, 2018, SIP revision, as sufficient for the purposes of satisfying the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS). In addition, this action converts the EPA's December 21, 2016, conditional approval for certain infrastructure provisions relating to Massachusetts's NNSR air permit program to full approval. This action is being taken under the Clean Air Act.
