Infrastructure SIPs

When EPA establishes a new National Ambient Air Quality Standard (NAAQS) or revises an existing NAAQS, the federal Clean Air Act requires Washington to develop an infrastructure State Implementation Plan (SIP). The infrastructure SIP demonstrates that Washington has the necessary legal authority, regulatory structure, and sufficient resources to implement the NAAQS statewide.

Infrastructure SIPs:

SIP Title Status

Infrastructure SIP for the 2010 Nitrogen Dioxide, 2008 Ozone, and 1997, 2006, and 2012 Fine Particulate Matter National Ambient Air Quality Standards

This SIP submittal proves Washington’s authority to control sources and limit emissions of nitrogen dioxide, ozone, and fine particles. Ecology proposes to add Ecology’s existing requirement that permits will be issued only after permit fees are paid.

Public comment period: July 25, 2014 - August 27, 2014

Rules

Washington rules are submitted with a SIP to provide an enforceable means to carry out the control strategy in the SIP.  Washington may also submit rules or rule updates without a SIP to satisfy federal requirements or as a state initiative to “strengthen the SIP” (improve pollution control programs).

When EPA approves a rule as part of Washington’s SIP, the rule becomes “federally-enforceable.”  That is, if Washington does not implement the rule, EPA can step in and enforce the rule at the federal level.

Current proposals to include state and local air quality rules in the SIP:

SIP Title Status
Chapter 173-433 WAC, Solid Fuel Burning Devices (revised)

Rule proposed on 3/4/14. See Federal Register Notice.

Chapter 173-476 WAC, Ambient Air Quality Standards

Rule proposal approved on 3/4/14. See Federal Register Notice.

Chapter 173-400 WAC, General Air Quality Regulations (revised)

Updated rule submitted in 1/14.


Program SIPs

Some SIPs satisfy programs or parts of programs required by the Clean Air Act.  The subjects addressed by these SIPs can be quite diverse. One example is the Motor Vehicle Inspection and Maintenance Program, more commonly known as the Emission Check Program. This program is required for carbon monoxide and ozone nonattainment areas. Other examples include the Washington State Visibility Protection Program and the 1998 Smoke Management Program.
