Document Description
Amendments to Rules 9-4 and 9-6 which govern appliance point of sale emissions standards.
Rule 9-4 applies to the natural gas-fired space-heating furnaces commonly found in single-family homes, and Rule 9-6 applies to natural gas-fired water heaters commonly found in residential and commercial applications. Space and water-heating appliances generate a large portion of nitrogen oxide (NOX) emissions from sources in the Bay Area. NOx is formed during natural gas combustion when ambient nitrogen and oxygen combine at high temperatures. The amendments substantially reduce NOX emissions from these appliances.?The amendments include a zero NOx standard for both space and water heating appliances that applies when new appliances are sold and installed beginning in 2027. The amendments also include the introduction of an ultra-low NOx standard to Rule 9-4 for furnaces starting in 2024, as well as additional updates to definitions, testing and certification requirements and other clarifications.
