NOTICE OF PUBLIC HEARING BAY AREA AIR QUALITY MANAGEMENT DISTRICT PROPOSED AMENDMENTS TO AIR DISTRICT REGULATION 11: HAZARDOUS POLLUTANTS, RULE 18: REDUCTION OF RISK FROM TOXIC AIR CONTAMINANTS AT EXISTING FACILITIES Notice is hereby given that the Board of Directors of the Bay Area Air Quality Management District (Air District) will conduct a public hearing on June 3, 2026, in the 1st floor Board Room, 375 Beale Street, San Francisco, California, at 10:00 a.m., or as soon thereafter as the matter may be heard, to receive testimony on proposed amendments to Air District Regulation 11: Hazardous Pollutants, Rule 18: Reduction of Risk from Toxic Air Contaminants at Existing Facilities (Rule 11-18) and on the proposal to adopt updates to the Rule 11-18 Implementation Procedures. The proposed amendments to Rule 11-18 include measures to expedite the approval of facility-wide Health Risk Assessments (HRAs), as well as other changes that would improve implementation efficiency of this rule. These proposed amendments focus on measures aimed at accelerating risk reduction and improving program efficiency to implement the requirements of the Rule as soon as feasible. The amendments are expected to expedite not only the overall implementation of the Rule but also the reduction of toxic emissions and health risks from affected facilities. Air District staff has also developed proposed updates to the Rule 11-18 Implementation Procedures, which include aligning with the proposed amended rule language; improving clarity and readability; and defining the role, scope, and process for a Dispute Resolution Panel that is expected to hear disputes between refineries and the Air District about technical issues. At the June 3, 2026 meeting, the Board of Directors will consider adopting these amendments to Rule 11-18 and updates to the Rule 11-18 Implementation Procedures. Air District Staff has prepared a written analysis describing the regulatory context of the amendments pursuant to California Health and Safety Code § 40727.2, as well as an addendum to the Environmental Impact Report (EIR) pursuant to the California Environmental Quality Act (CEQA) describing the amendments and discussing why a subsequent or supplemental EIR is not required.
