We propose revisions to Washington's air quality State Implementation Plan. These revisions show Washington's ability to attain, maintain, enforce, and implement federal air quality standards for 2015 ozone and 2010 sulfur dioxide through infrastructure requirements, including:
- Permitting programs
We have scheduled a tentative public hearing for Aug. 29, 2019, at 3 p.m. If we do not receive a request for a public hearing by 5 p.m. on August 15, 2019, we will cancel the hearing. We will update this web page with hearing information.
To request a public hearing, use one of the ways listed above.
To request ADA accommodation for the public hearing, email Ecology's ADA coordinator by August 15, 2019. Or call 360-407-6831, 711 (relay service), or 800-833-6384 (TTY).
Infrastructure state implementation plans
When EPA revises or issues a new National Ambient Air Quality Standard, the federal Clean Air Act requires each state to adopt and submit to EPA a plan, called an Infrastructure State Implementation Plan. An infrastructure plan shows how the state will implement, meet, and enforce federal standards for specific air pollutants, such as nitrogen dioxide, particles (also called particulate matter), lead, and ozone. The plan describes the infrastructure Washington has in place to protect air quality, such as:
- Legal authority to implement federal standards.
- Rules adopted in the plan to meet federal standards.
- Air monitors to measure air pollution and determine compliance with the federal standards.
- Funding and resources.
- Permitting and other programs.
- Studies about how air pollution travels to neighboring states.
Rule state implementation plans
Washington’s plan includes current state and local rules to reduce air pollution and meet federal air quality standards. When state and local agencies revise or add new rules in the plan, we submit those updates to EPA.
