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.

California Emissions
Estimator Model (CalEEMod)
The San Joaquin Valley
Air Pollution Control District transitioned from
using URBEMIS to 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
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.
Transition from
CalEEMod 2016 to CalEEMod 2020
The San Joaquin Valley
Air Pollution Control District transitioned to the
recently updated version of the California Emissions
Estimator Model (CalEEMod), version 2020 which is
EPA and District APCO approved, when reviewing or
preparing air impact assessments in compliance with
provisions of District Rule 9510 (Indirect Source
Review). The updated CalEEMod 2020 version,
