Procedures for Determining Localized Carbon Monoxide 
Concentrations (Hot-Spot Analysis) for Transportation Conformity Under 
the Clean Air Act in Washington State

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: Notice is hereby given that EPA, in accordance with the 
regulations has approved a `different procedure' submitted on November 
7, 2005 for determining localized carbon monoxide (CO) concentrations 
(hot-spot analysis) for Transportation Conformity under the Clean Air 
Act in Washington State.

FOR FURTHER INFORMATION CONTACT: Wayne Elson, U.S. EPA, Region 10 (AWT-
107), 1200 Sixth Ave., Seattle, WA 98101; (206) 553-1463 or 
[email protected], or Mia Waters, Washington State Department of 
Transportation, 15700 Dayton Avenue North, PO Box 330310, Seattle, WA 
98133; (206) 440-4541 or [email protected].

SUPPLEMENTARY INFORMATION: This is a notice of EPA's approval of the 
Washington State Intersection Screening Tool (WASIST) for carbon 
monoxide (CO) concentrations (hot-spot analysis) for Transportation 
Conformity under the Clean Air Act in Washington State submitted by the 
Washington State Department of Transportation on November 7, 2005. This 
`different procedure' was developed through the interagency 
consultation process and is consistent with 40 CFR 93.105. The basis 
for this approval is provided by 40 CFR 93.123 (a)(1). A letter 
approving WASIST was sent to Washington State Department of 
Transportation on February 2, 2006. The purpose of WASIST is to provide 
a different procedure to ensure that highway projects in Washington 
state will not cause or contribute to any new localized CO violations 
or increase the frequency or severity of any existing CO violations in 
CO nonattainment and maintenance areas consistent with 40 CFR 93.116. 
This different procedure will result in a substantial cost savings to 
governments in Washington when making project level CO hot-spot 
transportation conformity demonstrations for highway projects.

    Authority: 42 U.S.C. 7401-7671q.

    Dated: February 6, 2006.
L. Michael Bogert,
Regional Administrator, Region 10.
