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.

Clean Air Plan

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.

San Luis Obispo County APCD CEQA Tools

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 ModelThe 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.  More Arrow icon
