What is a rule?

APCD rules are specific regulations designed to limit air pollution. While a rule can take many shapes, it often outlines requirements for a specific type of operation or source of pollution. Examples of such operations include: open burning, gasoline storage and dispensing, oil and gas processing, automotive coating, and dry cleaning operations.

Each rule generally contains a statement of conditions under which the rule applies, the definitions of terms, the requirements of the rule, and any potential exemptions from the rule.


Under what authority does the APCD adopt and enforce rules?

The California Health and Safety Code gives the APCD primary responsibility for controlling air pollution from stationary sources in order to protect the public’s health. This responsibility includes the authority to develop, adopt, and enforce rules.


What opportunity does the public have to comment on proposed rules?

There are various opportunities for public input in the rule-making process. The public is invited to attend workshops, Community Advisory Council Meetings, and adoption hearings. For more details, see the Rule Development Process.


Which rules apply to my type of business?

In addition to the prohibitory rules listed above, businesses must comply with Regulation VIII – New Source Review. Some business may also be subject to the requirements of Regulation IX – New Source Performance Standards, Regulation X – National Emission Standards for Hazardous Air Pollutants, and/or Regulation XIII – Part 70 Operating Permit Program.

Please contact our Engineering and Compliance Division to ensure you are complying with all applicable rules. For more information on the APCD’s New Source Review or the permit process, see the Permit Services and Engineering section of this website or contact our Business Assistance Program.

 How can I tell if my business is in the Northern or Southern Zone of Santa Barbara County?

The map available here shows the Northern and Southern Zones. For specific legislative citations, see Rule 102 (the definition of “Zones of Santa Barbara County” on the last page) and Sections 60103(b) and 60104(c) of Title 17 of the California Administrative Code as written on December 21, 1968. It should be noted that presently all of Santa Barbara County is within the South Central Coast Air Basin.  In 1976, the California Air Resources Board amended the air basin designations (California Administrative Code, Title 17, Sections 60103 and 60104). Those amendments removed the Southern Zone of Santa Barbara County from the South Coast Air Basin and placed the entire County into the South Central Coast Air Basin.
