Roadway Protocol

NOTICE:

On January 25, 2018, the Mobile Sources Air Toxics Protocol replaced this Roadway Protocol.  The Sac Metro Air District is continuing to provide access to the Roadway Protocol for historical reference.

 

Visit the Mobile Sources Air Toxics Protocol website for the most current Sac Metro Air District guidance.

 

The Recommended Protocol for Evaluating the Location of Sensitive Land Uses Adjacent to Major Roadways (Roadway Protocol) provides guidance to jurisdiction planners on assessing and disclosing potential cancer risk of sensitive receptors exposed to diesel particulate matter from major roadways.

The Sac Metro Air District Board approved the Roadway Protocol on October 23, 2008.

The current Roadway Protocol reflects year 2011 emissions and traffic data from EMFAC2007.
