Rules, Regulations & Plans

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.

Proposed Revisions to Rules 430 & 431

Rule 430, Control of Oxides of Nitrogen from Industrial, Institutional, and Commercial Boilers, Steam Generators, and Process Heaters, and Rule 431, Stationary Internal Combustion Engines, are proposed for revision to reference new source review requirements from Rule 204 that were not previously referenced in the current rules and to add flexibility to Rule 430 for the use of alternative source test methods if approved by the Air Pollution Control Officer.  The proposed revisions do not add any additional requirements or regulations, but instead draw attention to existing requirements in other District Rules that are not referenced in these rules.

The proposed changes will be discussed at the next APCD Board Meeting on November 12, 2014, at 9:00am in the Board of Supervisors Chambers in the County Government Center. 

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.
