The California Air Resources Board (CARB) will present an overview of the draft supplemental report to the “AB 1900 Biogas Recommendations” report published by the Office of Environmental Health Hazard Assessment (OEHHA) in 2020, pursuant to the requirements of Assembly Bill 1900 (AB 1900). The report includes CARB’s updated recommendations regarding source testing requirements. Materials for this event, including copies of the presentation, will be available prior to the workshop on the Short-Lived Climate Pollutants Program: Meetings & Workshops webpage. A link to submit written feedback will be posted to the same page on the day of the workshop. Staff will accept stakeholder comments following the workshop through 5:00 pm on November 1, 2022.

Background

AB 1900 requires OEHHA and CARB to compile a list of constituents of concern (COC) that could pose risks to human health and that are found in biogas at concentrations that significantly exceed the constituents in natural gas. AB 1900 further requires the California Public Utilities Commission (CPUC) to adopt, by rule or order (1) standards for biomethane that specify the concentrations of COC that are reasonably necessary to protect public health and ensure pipeline integrity and safety, and (2) requirements for monitoring, testing, reporting, and recordkeeping. The bill ensures that no entity can inject biogas in a common carrier pipeline without meeting these standards and requirements.
