Chapters 173-491, 173-400, 173-455 WAC

This rulemaking is on hold.

This rulemaking proposes to change three rules:

• Emission Standards and Controls for Sources Emitting Gasoline Vapors - Chapter 173-491 WAC – establishes air quality requirements to control emissions from sources of gasoline from gasoline dispensing facilities, gasoline loading terminals, bulk gasoline plants, and gasoline storage tanks.
• General Regulations for Air Pollution Sources - Chapter 173-400 WAC – establishes the regulatory framework to ensure that healthy air quality exists in Washington, including meeting federal air quality standards.
• Air Quality Fee Rule - Chapter 173-455 WAC – establishes air quality-related fees for businesses regulated by Ecology.

The changes will:

• Update outdated requirements and make other administrative changes for sources emitting gasoline vapors to align with federal rules.
• Not include Stage II requirements for large volume gas stations.
• Revise Chapters 173-400 and 173-455 WAC to align with changes to Chapter 173-491 WAC.
• Adopt by reference new federal rules and revisions to existing federal rules in Chapter 173-400 WAC.
