The Indirect Source Review (ISR) rule, which went into effect March 1, 2006, requires developers of larger residential, commercial and industrial projects to reduce smog-forming and particulate emissions generated by their projects. The rule is expected to reduce nitrogen oxides and particulates throughout the San Joaquin Valley by more than 10 tons per day by 2010.

New California Emissions Estimator Model (CalEEMod)

The San Joaquin Valley Air Pollution Control District is transitioning to the use of the California Emissions Estimator Model (CalEEMod) when reviewing or preparing air impact assessments in compliance with provisions of District Rule 9510 (Indirect Source Review), California Environmental Quality Act (CEQA), and National Environmental Policy Act (NEPA), within the San Joaquin Valley air basin. CalEEMod is the newest computer emissions estimating model developed by the California Air Pollution Control Officers Association (CAPCOA). The model calculates criteria pollutant and greenhouse gas (GHG) emissions from a variety of land uses, including residential, commercial, retail, and industrial projects. CalEEMod also calculates the benefits of implementing mitigation measures, including GHG mitigation measures.

The District’s Transition Schedule to CalEEMod

District Rule 9510 (Indirect Source Review)

  • Air Impact Assessments deemed “Complete” before July 1st, 2012 will be analyzed using URBEMIS 2007. During this period, submitted applications that used CalEEmod will be reanalyzed by the District using URBEMIS 2007.
  • All Air Impact Assessments deemed “Complete” on or after July 1st, 2012 must be analyzed using CalEEMod.

Environmental Documents prepared for CEQA and NEPA

  • Before July 1st, 2012, for projects where the Lead Agency has released the draft environmental document for public review, the District will accept the use of any appropriate model, including CalEEMod, to perform the Air Quality Impact Analysis.
  • On or after July 1st, 2012, for projects where the Lead Agency has not released the draft environmental document for public review, the District recommends the use of CalEEMod to perform the Air Quality Impact Analysis.

The District recognizes that CEQA can involve long lead times, and if Lead Agencies are acting on projects with significant modeling already completed before the July 1st, 2012 deadline, please contact the District at (559) 230-6000 for project-specific discussions.

Rule 9510, Indirect Source Review: Air District prevails in national suit over development project construction emissions
On September 19, 2008, the U.S. District Court in Fresno struck down a lawsuit contesting the regulations over development project construction emissions. The Court affirms that the District has the authority to regulate the effects of motor vehicles and equipment attracted to development sites. Press release

The District has released the 2008 Annual Report on the District's Indirect Source Review Program for the period March 1, 2007 to February 29, 2008. Click here to view.

The District has released new application forms for Residential, Non-Residential, and Mixed Use projects. New instructions and the proposed AIA form will be forthcoming.

The District held a Transportation/Transit Workshop on Wednesday, Jun 7, 2006. The presentation can be found under "Presentations" in the Resources area.

The Fee Deferral Schedule and the Change of Project Developer Forms have been added to the Forms and Applications Page.

URBEMIS Templates are now available in Resources. These templates incorporate the District Recommended Standard Changes to Defaults.
