San Joaquin Valley Unified Air Pollution District

This page updated July 15, 2003.

Transportation Conformity

The San Joaquin Valley consists of eight separate counties, each responsible for ensuring that their short-and long-term transportation plans help attain federal clean air standards. The regional transportation planning agencies prepare transportation air quality conformity analyses which demonstrate that the motor vehicle emissions resulting from planned transportation activities are consistent with the regions' State Implementation Plans (SIPs). In the San Joaquin Valley, motor vehicle emissions budgets have been set in SIPs for carbon monoxide (CO) and the ozone precursors reactive organic gases (ROG) and nitrogen oxides (NOx). Alternative conformity tests are used to demonstrate conformity for particulate matter (PM-10) and PM-10 precursors since there are no applicable motor vehicle emissions budgets for these pollutants.

The currently applicable motor vehicle emissions budgets in the San Joaquin Valley are as follows:

2002 ROP Budget Documentation


On ______, ARB submitted to U.S. EPA the San Joaquin Valley Unified Air Pollution Control District's (District) 2003 PM-10 SIP. The 2003 PM-10 SIP contains motor vehicle emissions budgets for directly emitted PM-10 and the PM-10 precursor NOx for 2005, 2008, and 2010. These budgets are currently undergoing adequacy review by U.S. EPA. Upon a positive adequacy finding from U.S. EPA, the 2005, 2008, and 2010 budgets would become applicable for transportation conformity purposes. The emissions budgets identified in the PM-10 SIP are as follows:

 

Pending PM-10 Plan Budgets for 2005
(tons per day)

Pending PM-10 Plan Budgets for 2008
(tons per day)

Pending PM-10 Plan Budgets for 2010
