The SJVAPCD recommends a three-tiered approach to analysis based on
project size to allow quick screening of most projects for significant
impacts.
Small Project Analysis Level (SPAL)
The Small Project Analysis Level (SPAL) document can be found here.

Cursory Analysis Level (CAL)
The CAL is used to determine if significance thresholds have been exceeded on
projects not meeting the SPAL criteria.
- Estimate mobile and area source emissions using CalEEMod
- Screen for CO impact/use CO Protocol or CALINE4 dispersion model if
needed.
- If source of hazardous air pollutants or odors or is near such a source,
contact the SJVUAPCD.
- If demolition or renovation of existing buildings, contact the District
for asbestos requirements.
- Identify feasible mitigation measures and quantify benefit using CalEEMod
7G
- If impacts are identified as significant and cannot be mitigated to less
than significant prepare an EIR with full analysis.

Full Analysis Level (FAL)
The Full Analysis Level (FAL) is the level of analysis usually required for
an EIR. It requires all the elements of the previous two levels and an air
quality report that fully describes the air quality impacts to the public.
- Estimate mobile and area source emissions with CalEEMod. For general
plans and large specific/community plans use DTIM2 if transportation demand
model available, otherwise use MVEI7G (BURDEN7G).
- Screen project for CO impacts, use CO Protocol or CALINE 4 if needed.
- If source of hazardous air pollutants or odors, or is near such a source,
contact the SJVUAPCD.
- If SJVUAPCD identifies as potentially significant source of hazardous air
pollutants, a health risk assessment will be required.
- Prepare an air quality report containing:
- existing air quality conditions;
- analysis of project air quality impacts;
- mitigation measures; and
- results of modeling as technical appendices.

Recommended Thresholds of Significant
Impact
- Ozone Precursor Emissions
Particulate Matter with a diameter of 10 microns or less (PM10) 15 tons/year
Particulate Matter that is 2.5 microns or less (PM2.5) 15 tons/year
It should be noted that although compliance with SJVAPCD Regulation VIII substantially reduces project specific fugitive dust emissions, it may not be sufficient to reduce project specific emissions to less than significant levels. Furthermore, Regulation VIII does not reduce construction exhaust emissions.
- Hazardous Air Pollutant Emissions
