gas-powered appliances

Southern California air regulators can proceed with new limits on gas-powered appliances, including water heaters, after a 2-1 ruling by the 9th Circuit Court of Appeals upheld restrictions in four Los Angeles-area counties. The decision impacts approximately 1.3 million water heaters and industrial boilers in L.A., Orange, Riverside, and San Bernardino counties, with the Sierra Club listed as a defendant.
