Energy Facility Site Evaluation Council Rule Change

State Implementation Plan

March 13, 2023 - April 21, 2023, 11:59 p.m.

We propose to send EPA the revised air quality State Implementation Plan (SIP) to include Energy Facility Site Evaluation Council's (EFSEC) updated rule for startup, shutdown, and malfunction.

The revised SIP:

  • Removes EFSEC's outdated provisions
  • Adds their current provisions

Documents for review:

Tentative public hearing:

(if requested by April 12, 2023)
April 18, 2023, 6 p.m. online

We will cancel the public hearing if we do not receive a request by April 12, 2023. We will update this webpage if the public hearing is cancelled. To comment or request a public hearing, use one of the ways listed below.


State Implementation Plan (SIP) is a general cleanup plan for air.  It describes how Washington carries out, maintains, and enforces national air quality standards.

The SIP explains how Washington will lower air pollution from sources like transportation, wood smoke, and industry. Sections of the plan are customized to meet regional air quality needs.
