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.

CEQA 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. 

Construction Activity Management Plan: A Construction Activity Management Plan maybe required as part of the construciton activites assoicated with a variety of project types. Please refer to the CEQA Handbook to determine when a CAMP is needed. The APCD has developed a guideline to assist with preparation of a CAMP. This guideline is available for download here or as an appendix in the CEQA Handbook.

ModelsTo assist individuals with CEQA requirements the District has developed several brochures that outline the general Air Quality requirements and specific information for residential, commercial and industrial development.  For general   estimating emissions from land development projects, the District recommends using the most recent version of the URBEMIS model. This model is available is available for a free download. More Arrow icon

MappingThe California Air Resources Board (CARB) has determined that emission from sources such as roadways and distribution centers and, to a lesser extent gas stations, certain dry cleaners, marine ports and airports as well as refineries can lead to unacceptably high health risk from diesel particulate matter and other toxic substances. The APCD has compiled and maintains a list of such sources within SLO County; this data is being made available here in GIS format. It is the APCD's intention that this data will be used to avoid citing residential and sensitive receptor developments in close proximity to sources of pollution associated with cancer risk.

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
