Rules & Regulations
The APCD is primarily responsible for managing local air quality by regulating
emissions from stationary sources of air pollution. Standards for motor vehicle
emissions are set by the California Air Resources Board (ARB), and apply uniformly
statewide. The APCD Rules and Regulations are adopted by the Air Pollution Control Board
and apply to the area and activities within the District.
The California Air Resources Board maintains a website that stores rules and
regulations for all Districts throughout the state.

County APCD's Rules and Regulations.
Land Use and CEQA
As part of the California Clean Air Act, the APCD is required to develop a plan to
achieve and maintain the state ozone standard by the earliest practicable date.
The Clean Air Plan (CAP) outlines the District's strategies to reduce ozone precursor
emissions from a wide variety of stationary and mobile sources. The 2001 CAP was adopted by the Air
Pollution Control Board at their hearing on
March 26, 2002.
The 2001 CAP is available for download either as the entire
document or broken into individual chapters.

PM Report
In 2003, the California Legislature enacted Senate Bill 656 (Sher),
to reduce public exposure to particulate matter (PM10 and PM2.5
collectively referred to as PM). SB 656 required the
California Air Resource Board (ARB) in consultation with local air
pollution control districts, to develop and adopt a list of PM
reduction strategies.
San Luis Obispo County Air Pollution Control District Board
adopted the PM Report and
associated control measures in July 2005.
CEQA Handbook and Associated Tools: The California Environmental Quality Act (CEQA) was created to ensure that
environmental impacts from new development are addressed and adequately mitigated. The
District's CEQA Handbook provides information on the District's significance
thresholds for determining potential air quality impacts from proposed residential and
commercial development and provides recommendations on the level of mitigation necessary
to reduce those impacts. Appendix A to the CEQA Handbook outlines
the building permit requirements for facilities potentially subject
to air district permitting. The CEQA Handbook was last updated on December 2, 2009. The CEQA Handbook and tools listed below are intended to assist with CEQA reviews.
- CEQA
Handbook
- Standard Language File -Frequently used language for CEQA review
- Unpaved Road Data - Screening table for vehicle trips that would exceed APCD's CEQA PM 10 threshold
- Construction Activity Management Plan The APCD has developed a guideline to assist with preparation of a CAMP. This guideline is available in Section 4 of the CEQA Handbook (see link above).
CalEEMod Model: The California Emission Estimator Model (CalEEMod) is the emissions estimation model the District recommends using for landuse project. The model is free and available for download from the link below. The most recent verison of the model should be used.
Health Risk Assessment: Screening level health risk assessments (HRA) may be required as part of the CEQA review process. A tool is available to assist with this screening. The tool and instruction on how to use the tool are listed below. Please note this tool is intended for screening only. A more detail assessment maybe required depending upon the results from the screening tool.

ARB's Air Quality and Land Use Handbook
ARB's Air Quality and Land Use Handbook:
As part of the Air Resources Board's (ARB) Community Health Program,
they have developed an Air Quality and Land Use Handbook (Handbook)
which is intended to serve as a general reference guide for
evaluating and reducing air pollution impacts associated with new
projects that go through the land use decision-making process.
