Air Plan Approval; VT; Nonattainment New Source Review and Prevention of Significant Deterioration Permit Program Revisions; Infrastructure Requirements for National Ambient Air Quality Standards
The Environmental Protection Agency (EPA) is proposing to approve several different revisions to the State Implementation Plan (SIP) submitted to EPA by the Vermont Department of Environmental Conservation (VT DEC). On May 23, 2017, Vermont submitted revisions to EPA satisfying the VT DEC's earlier commitment to adopt and submit revisions that meet certain requirements of the federal Prevention of Significant Deterioration (PSD) air permit program. Vermont's submission also included revisions relating to the federal nonattainment new source review (NNSR) permit program. This action proposes to approve those revisions and also proposes to fully approve certain of Vermont's infrastructure SIPs (ISIPs), which were conditionally approved by EPA on June 27, 2017. Additionally, EPA is proposing to approve several other minor regulatory changes to the SIP submitted by VT DEC on May 23, 2017. This action is being taken in accordance with the Clean Air Act.

EPA is approving Vermont's Progress Report on the basis that it addresses the progress report and adequacy determination requirements for the first implementation period covering through 2018.
