Good Neighbor (Transport) State Implementation Plan

Comment deadline: December 23, 2019

Clean Air Act Section 110(a)(2)(D)(i)(I) requires each state to submit to EPA new or revised SIPs that "contain adequate provisions prohibiting, consistent with the provisions of this subchapter, any source or other type of emissions activity within the State from emitting any air pollutant in amounts which will contribute significantly to nonattainment in, or interfere with maintenance by, any other state with respect to any such national primary or secondary ambient air quality standard." The EPA often refers to CAA Section 110(a)(2)(D)(i)(I) as the good neighbor provision and to SIP revisions addressing this requirement as Good Neighbor SIPs or interstate transport SIPs.

The Department's proposed Good Neighbor SIP supplements its Section 110(a)(1) and (2) Infrastructure SIP to demonstrate that emissions from sources in Maine do not significantly contribute to nonattainment in, or interfere with maintenance by, any other state with respect to the 2015 ozone NAAQS. The Departments analysis of recent EPA and Ozone Transport Commissions (OTC) 2023 modeling demonstrates that Maine meets its good neighbor requirements for the 2015 NAAQS. This plan will be submitted to EPA as a revision to Maines State Implementation Plan.

Pursuant to federal law, interested parties are publicly notified of the proposed SIP amendment and are provided an opportunity for comment. Written comments may be submitted by mail, e-mail or fax to the contact person before the end of the comment period. To ensure the comments are considered, they must include your name and the organization you represent, if any.
