Learn about the Air District's process for developing amendments to Regulation 6, Rule 5, which would further reduce particulate matter emissions from petroleum refinery fluidized catalytic cracking units.
Find out about the status and anticipated timeline of the rule development process. Information on hearings, workshops, and other events is provided below, along with supporting documents and materials.
Air District staff has developed proposed amendments to Regulation 6, Particulate Matter, Rule 5: Particulate Emissions from Refinery Fluidized Catalytic Cracking Units (Rule 6-5). Rule 6-5 was originally adopted by the Air District Board of Directors in December 2015, and subsequently amended in December 2018 for minor clarifications and revisions. The purpose of the current rule development effort for amendments to Rule 6-5 is to further reduce emissions of particulate matter, including condensable particulate matter, from petroleum refinery fluidized catalytic cracking units (FCCU), which are some of the largest individual sources of particulate matter emissions in the Bay Area.
This current rule development effort for amending Rule 6-5 follows previous Air District rulemaking and planning actions to address emissions from these sources. Rule 6-5 was originally adopted in 2015. The Air District’s 2017 Clean Air Plan and AB 617 Expedited Best Available Retrofit Control Technology (BARCT) Implementation Schedule identified the need to further evaluate and consider additional efforts to control particulate matter emissions from these sources.
The Air District Board of Directors will conduct a public hearing on Wednesday, June 2, 2021, to consider adoption of the proposed amendments to Rule 6-5. The Air District released a Notice of Public Hearing, proposed amendments to Rule 6-5, and a Staff Report in March 2021 and accepted public comments on these materials. The Air District has released the Final Proposal Package, including the proposed amendments to Rule 6-5, Final Staff Report, and a Summary of Comments and Responses:
