We are proposing to send the federal Environmental Protection Agency (EPA) our revised air quality SIP, which includes updated rules about emissions from energy facilities. Learn about these rule changes and how to get involved with the process.
About this rule
A 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. We customize sections of the plan to meet regional needs for air quality.
The revised SIP:
- Removes outdated provisions
- Adds current provisions
