Current Rules & Rulemaking

Yolo-Solano AQMD adopts rules that help fulfill its mission to protect human health and property from the harmful effects of air pollution. These rules are based on federal and state air quality requirements established by the United States Environmental Protection Agency (EPA) and California Air Resources Board (ARB).

The Rulemaking Process

The District’s rulemaking process is fully transparent. Per state law, the District provides advance public notification of proposals to amend or develop rules, and seeks public comment on rulemaking.

Here are the steps in the District’s rulemaking process.

  1. District staff determines that a new rule or an existing rule revision is necessary. This could be due to a new federal or state air quality requirement, a public health interest or a new for clarification in the rules due to changes in industrial products or processes.
  2. Staff develops a draft staff report and draft rule language.
  3. Staff holds one or more public workshops to discuss the draft rule requirements with stakeholders and the general public and to solicit comments on the draft language.
  4. Staff sends the draft rule to ARB and the EPA for their review and comments.
  5. Staff reviews comments and incorporates changes as appropriate into the draft rule language.
  6. The District provides ample advance notice of a public hearing on the rulemaking.
  7. Staff presents the new or revised rule to the Board of Directors for consideration and a public hearing is held.
  8. The Board determines whether to adopt the rule as proposed.
  9. If necessary, staff issues a public advisory to educate affected sources of the new or amended rule requirements.
