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 State Implementation Plan 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.
