Air Quality Program

Infrastructure, Rule, and Program SIPs

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 SIP Title Status

Interstate transport of lead, nitrogen dioxide, ozone, and fine particles air pollution.

 

Ecology accepted comments from March 9, 2015 through April 10, 2015.

EPA proposed to partially approve and partially disapprove the NO2 and Lead portions of the transport SIP. 

EPA comment period from May 27, 2015 to June 26, 2015.

EPA approved the ground level ozone portion of the interstate transport SIP on December 15, 2015.

EPA approved the fine particle portion of the interstate transport SIP on July 30, 2015.

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

EPA partially approved part of the SIP submittal on 1/14/15.

EPA proposed to partially approve another part  of the SIP submittal on 10/17/14 in a separate action.

Infrastructure SIP Certification for the 2008 Lead National Ambient Air Quality Standards

EPA partially approved this SIP on 7/23/14.

Infrastructure SIP Certification for the 1997 8-Hour Ozone National Ambient Air Quality Standards

EPA partially approved this SIP on 5/24/12.

Interstate Transport SIP State Implementation Plan for 1997 8-Hour Ozone and PM2.5 National Ambient Air Quality Standards

EPA approved this SIP on 8/27/07.


Rule SIPS

Washington usually submits rules (Washington Administrative Codes or WACs) along with a SIP as enforceable means to carry out the control strategy in any type of SIP. Sometimes, rules are even submitted as standalone SIP revisions. 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 or citizens can step in and enforce the rule at the federal level.

Rule SIP Title Status

Including parts of revised Chapters 173-400 and 173-476 WAC in the Washington SIP

Ecology is proposing portions of recent revisions to Chapters 173-400 and 173-476 WAC be included in the Washington SIP. Ecology is also proposing portions of the recent revision in Chapter 173-400 be included in Benton Clean Air Agency (BCAA) SIP.

Ecology comment period:  April 18 – May 27, 2016

If requested by 5 pm May 17, 2016, Ecology will be holding  a hearing on:

May 24 at 2:00 p.m.

Ecology is proposing changes to Chapters 173-400, 173-423, and 173-476 WAC. Benton Clean Air Agency is proposing that portions of revisions to Chapter 173-400 WAC be included in the SIP.

Ecology comment period: February 25 – April 12, 2016

Ecology will be holding two consecutive hearings.

  • Hearing 1 – comments on the proposed rule amendments

Including Benton Clean Air Agency Regulation 1 in the SIP

Benton Clean Air Agency (BCAA) Regulation 1 was approved by the BCAA local board of directors. Ecology held a comment period from July 10 to August 14, 2015. Ecology adopted the updated rules on August 19, 2015 and submitted them to EPA for approval into the State Implementation Plan (SIP) on August 25, 2015.

EPA granted final approval on November 17, 2015.

Questions? Contact Laurie Hulse-Moyer

Including revised Spokane Regional Clean Air Agency Regulation 1, Article VIII, Solid Fuel Burning Devices, in the Washington SIP

After carefully consideration of the oral and written comments received, Ecology adopted the SIP revision on July 10, 2015 and submitted it to EPA for approval. 

 EPA approved this submittal on September 28, 2015.

For more information contact Joanna Ekrem, 360-407-6826.

Including revised chapter 173-400 WAC, General Air Quality Regulations, in the Washington SIP

Ecology submitted this SIP revision to EPA in January 2014.

EPA partially approved Ecology’s general air quality rules on October 3, 2014.

EPA approved Ecology’s nonattainment new source review rules on November 7, 2014.

EPA proposed to approve the Prevention of Significant Deterioration program, the final portion of the SIP submittal on January 7, 2014.

Including revised chapter 173-433 WAC, Solid Fuel Burning Devices, in the Washington SIP

EPA approved this SIP revision on April 9, 2014.

Including new chapter 173-476 WAC, Ambient Air Quality Standards, in the Washington SIP

EPA approved this SIP revision on 3/4/14.


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.

Program SIP Title Status

Revision to the BP Cherry Point Refinery BART Order

Ecology accepted comments from March 9, 2015 – April 10, 2015.
No comments were received.

Ecology submitted the documents to EPA on May 12, 2015.

EPA approved the Best Available Retrofit Technology (BART) alternative measure to reduce Nitrogen Oxides (NOx) at BP’s Cherry Point refinery located near Ferndale, on February 16 2016.

2010 Regional Haze SIP and 2011 Regional Haze SIP Updates

On December 6, 2012, EPA approved the Best Available Retrofit Technology (BART) determination for the TransAlta Centralia Generation LLC Coal-fired power plant in Centralia, WA.

On June 11, 2014, EPA partially approved and partially disapproved the 2010 Regional Haze Plan. EPA developed a Federal Implementation Plan (FIP) for the elements they did not approve.

EPA issued a final action to correct an error on November 24, 2014.

In addition, EPA also approved an alternate to BART for five BART emission units at the Tesoro Refining and Marketing refinery in Anacortes. An emission unit is an individual piece of equipment that emits air pollutants at a stationary source, such as steam generators, combustion turbines, or printing presses.
