Infrastructure, rule, & program plans

We submit plans as well as state and local rules to EPA that show Washington has tools in place to meet national air quality standards. Once approved by EPA, these plans for infrastructure, rules, and programs become part of Washington's State Implementation Plan (SIP) for air quality. Plans and rules in Washington's State Implementation Plan are enforceable by EPA and the public.

Public comment

We propose revisions to Washington's State Implementation Plan for air quality. These revisions show Washington's ability to attain, maintain, enforce, and implement federal air quality standards through infrastructure requirements and updated rules.

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 – like 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

Date submitted to EPA	Plan
9/30/19	State Implementation Plan: National Ambient Air Quality Standards: Infrastructure State Implementation Plan for 2015 Ozone and 2010 Sulfur Dioxide
2/7/18	Interstate Transport of Sulfur Dioxide and Ground-Level Ozone
2/7/18	Interstate Transport of Fine Particulate Matter
5/11/15	Interstate Transport of Lead, Nitrogen Dioxide, and Ground-Level Ozone
5/11/15	Interstate Transport of Fine Particulate Matter
9/22/14	Infrastructure SIP for the 2010 Nitrogen Dioxide, 2008 Ozone, and 1997, 2006, and 2012 Fine Particulate Matter National Ambient Air Quality Standard
4/14/14	Infrastructure SIP Certification for the 2008 Lead National Ambient Air Quality Standard

See the status of EPA action on infrastructure plans.

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.

Program state implementation plans

A program state implementation plan describes specific programs to protect air quality and meet federal air quality standards.

Plan	Description
Vehicle Inspection and Maintenance Program (also known as the Emission Check Program)	This program is required for carbon monoxide and ozone nonattainment areas. A nonattainment area is an area that does not meet an air quality standard. In May 2019, we submitted to EPA our plan to remove the vehicle inspection and maintenance program from the state implementation plan.
Regional Haze State Implementation Plan	This defines a strategy to improve visibility in our national parks and wilderness areas (Class 1 Areas). It documents existing conditions and identifies key sources of air pollution. We update this strategy periodically.
DNR's Draft Updated Smoke Management Plan	This is another part of the plan to improve visibility. It regulates forestry (silvicultural) burning on land managed by the Washington Department of Natural Resources.
