The purpose of this rulemaking is to align three air quality rules:
with the August 2018 amendments to Chapter 173-400 WAC — General Regulations for Air Pollution Sources. Ecology revised Chapter 173-400 WAC to comply with EPA’s direction in the Startup-Shutdown-Malfunction State Implementation Plan Call (SSM SIP Call) (80 FR 33840).
We are also proposing other changes to address stakeholders' concerns and improve readability.
