BAAQMD Regulation 11, Rule 18 Health Risk Assessment Update

January 12, 2024

Under Regulation 11, Rule 18, the Bay Area Air Quality Management District (BAAQMD) conducts health risk assessments (HRAs) for facilities whose emissions pose potentially high health risks. Facilities were ranked into two phases for evaluation: Phase I (36 total facilities) and Phase II. If a facility is found to exceed health risks, a Risk Reduction Plan will be required. After approval by the District, this Risk Reduction Plan will require implementation within 5 years.

As of the fourth quarter of 2023, the BAAQMD has calculated Prioritization Scores for all Phase I facilities and ranked each Phase I facility as either Top Priority (eight facilities), Medium Priority (13 facilities), or Low Priority (15 facilities). The BAAQMD is considering rulemaking in the 2023-2024 fiscal year to amend Rule 11-18 to streamline and expedite regulatory implementation.

More information and the list of Phase I facilities can be found at: https://www.baaqmd.gov/community-health/facility-risk-reduction-program.
