In one of the vital essential state environmental selections this yr, California air regulators adopted new guidelines designed to cut back methane leaks and higher reply to disastrous underground fires at landfills statewide.
California Air Sources Board members voted 12-0 on Thursday to approve a batch of recent rules for the state’s almost 200 giant landfills, designed to attenuate the discharge of methane, a robust greenhouse gasoline produced by decomposing natural waste. Landfills are California’s second-largest supply of methane emissions, following solely the state’s giant dairy cow and livestock herds.
The new necessities will power landfill operators to put in further air pollution controls; extra comprehensively examine methane leaks on components of landfills which can be inaccessible with on-the-ground monitoring utilizing new expertise like drones and satellites; and repair gear breakdowns a lot quicker. Landfill operators additionally can be required to restore leaks recognized via California’s new satellite-detection program.
The regulation is predicted to forestall the discharge of 17,000 metric tons of methane yearly — an quantity able to warming the ambiance as a lot as 110,000 gas-fired vehicles pushed for a yr.
It additionally will curtail different dangerous landfill air pollution, corresponding to lung-aggravating sulfur and cancer-causing benzene. Landfill operators can be required to maintain higher observe of excessive temperatures and take steps to attenuate the fireplace dangers that warmth may create.
There are underground fires burning in at the very least two landfills in Southern California — smoldering chemical reactions which can be incinerating buried rubbish, releasing poisonous fumes and spewing liquid waste. Regulators discovered explosive ranges of methane emanating from many different landfills throughout the state.
Through the three-hour Air Sources Board listening to previous the vote, a number of Californians who stay close to Chiquita Canyon Landfill — one of many identified websites the place rubbish is burning deep underground — implored the board to behave to forestall disasters in different communities throughout the state.
“If these guidelines have been already up to date, possibly my household wouldn’t be sick,” stated Steven Howse, a 27-year resident of Val Verde. “My home wouldn’t be on the market. My shut pal and neighbor would nonetheless stay subsequent door to me. And I wouldn’t be pleading with you proper now. You will have the ability to alter this.”
Landfill operators, together with corporations and native governments, voiced their concern concerning the prices and labor wanted to adjust to the regulation.

Lauren Sanchez, who was appointed chair of the California Air Sources Board in October, just lately attended the United Nations’ COP30 local weather convention in Brazil with Gov. Gavin Newsom. What she realized on the summit, she stated, made clear to her that California’s methane emissions have worldwide penalties, and that the state has an crucial to cut back them.
“The science is obvious, appearing now to cut back emissions of methane and different short-lived local weather pollution is the easiest way to right away gradual the tempo of local weather change,” Sanchez stated.
