SIP Revision Public Notice 03/14/2023

Air Rule Update:

EFSEC accepted public comment June 3, 2020 through July 20, 2020 for the revision of WAC 463-78 – General and operating permit regulations for air pollution sources. The purpose of the proposed rule revisions are to be consistent with Ecology and EPA rules and to ensure that EFSEC issued permits are in line with current EPA and Ecology regulations. Additionally, the Washington Air Quality State Implementation Plan (SIP) is pending update, and requires that EFSEC’s rules be updated to move forward. Because EFSEC would be adopting by reference rules that have already been through public comment via the department of Ecology’s rule making process, this update to EFSEC rules qualifies for the expedited process.
