Infrastructure, rule, & program plans

We submit plans as well as state and local rules to the Environmental Protection Agency (EPA) that demonstrate Washington has the tools in place to meet National Ambient Air Quality Standards. Once approved by EPA, these infrastructure and program plans and rules become part of Washington's State Implementation Plan (SIP) for air quality. Plans and rules in Washington's SIP are enforceable by EPA and the public.

Open for public comment

We are proposing to submit to EPA a revision to Washington’s SIP. Under state law, the vehicle inspection and maintenance (also known as vehicle I/M or emission check) program ends on December 31, 2019. This revision would update Washington’s SIP to remove the emission check program as a control measure.

Bajo la ley del estado, el programa de chequeo de emisiones de vehículos terminara el 31 de diciembre de 2019. Este plan actualiza el Plan de Implementación del estado de Washington para remocionar el programa de chequeo de emisiones. El plan muestra que la remoción del programa no resultara en calidad de aire malsano. Para más información sobre el plan, comuníquese con Joanna Ekrem, Programa de Calidad de Aire, al 360-407-6826.

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 a variety of parameters, such as nitrogen dioxide, 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 the National Ambient Air Quality Standards. When state and local agencies revise or add new rules in the plan, those updates are submitted to EPA.
