The Environmental Protection Agency (EPA) is proposing to approve 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 proposing to approve 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 will also convert 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.
