Learn about the Air District's process for amending to Regulation 9, Rules 4 and 6 to reduce emissions of nitrogen oxides from residential and commercial furnaces and water heaters in buildings in the Bay Area.
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 is currently evaluating potential amendments to two rules: Rule 9-4: Nitrogen Oxides from Fan Type Residential Central Furnaces and Rule 9-6: Nitrogen Oxides Emissions from Natural Gas-Fired Boilers and Water Heaters. These rules govern point of sale emission standards for small, typically residential and commercial, water and space heating systems.
The Air District is currently convening a Building Appliance Stakeholder Working Group to solicit stakeholder input in the development of regulatory amendments to further reduce emissions from commercial and residential space and water heating. The Air District is seeking both technical feedback as well as input on appropriate measures to ensure the rulemaking is equitable in process and outcomes through this workgroup. Initial outcomes from this workgroup and first draft language of regulatory amendments are anticipated to be brought to a public workshop in Summer 2021.
