Notice of 30-day Comment Period and Public Hearing – 2050 RTP Air Quality Conformity Timeline and Methodology

SANDAG is currently developing the 2050 Regional Transportation Plan (RTP), which is anticipated to be adopted in summer 2011 along with its air quality conformity determination. While the horizon year of this RTP is 2050, both the current version of the emissions model approved by the  U.S. Environmental Protection Agency (EMFAC 2007) and the new version of the model (EMFAC 2010), which is under development by the California Air Resources Board (CARB), only contain emissions factors to 2040.

Since no other emissions model is approved for use in conformity determinations by Metropolitan Planning Organizations in California, SANDAG is exploring options under the Transportation Conformity Rule to conduct the air quality conformity determination for its 2050 RTP. On September 17, 2010 the Transportation Committee accepted the draft proposed methodology for conducting the air quality conformity determination for the 2050 RTP for review and distribution for a 30-day comment period and scheduled a public hearing to solicit public comments on shortening the conformity timeline and proposed methodology for the regional emissions analysis for the October 15, 2010, Transportation Committee meeting to be held at SANDAG, 401 B Street, San Diego, CA 92101 at 8:30 a.m.

Questions or comments regarding this notice should be directed to Rachel Kennedy, Senior Transportation Planner at or (619) 699-1929
