Comment and Hearing Notice: Reasonably Available Control Technology (RACT) State Implementation Plan (SIP) Revision Under the 2008 8-Hour Ozone National Ambient Air Quality Standard (NAAQS)

Comment deadline: August 17, 2018

The Department is proposing to amend the Maine State Implementation Plan (SIP) to address requirements for the implementation of reasonably available control technology (RACT) pursuant to the 1990 Clean Air Act Amendments (CAA) and the U.S. EPA's "Final Rule to Implement the 2008 8-Hour Ozone National Ambient Air Quality Standard" (80 FR 12263; March 6, 2015). Under the CAA and federal rules, Maine must submit a demonstration that its current rules fulfill the 2008 8-hour ozone RACT requirements for all Control Technique Guideline (CTG) categories and all major, non-CTG sources. This demonstration can be made with either a new RACT determination or a certification that previously-required RACT controls represent RACT for the 2008 8-hour ozone standard.

After reviewing its existing rules, the Department has concluded that its existing regulations for CTG sources still represent RACT. The Department has also concluded that all major stationary sources of volatile organic compounds are meeting the RACT requirements.

This certification will be submitted to EPA as a revision to Maine's State Implementation Plan. Copies of this proposal are available upon request by contacting the Agency contact person or at the link below. Written comments may be submitted by mail, e-mail or fax to the contact person before the end of the comment period.
