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 pressure landfill operators to put in extra air pollution controls; extra comprehensively examine methane leaks on elements of landfills which might be inaccessible with on-the-ground monitoring utilizing new expertise like drones and satellites; and repair tools breakdowns a lot sooner. Landfill operators additionally can be required to restore leaks recognized by way of California’s new satellite-detection program.
The regulation is predicted to stop 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 12 months.
It additionally will curtail different dangerous landfill air pollution, comparable to lung-aggravating sulfur and cancer-causing benzene. Landfill operators can be required to maintain higher monitor of excessive temperatures and take steps to attenuate the fireplace dangers that warmth may create.
There are underground fires burning in no less than two landfills in Southern California — smoldering chemical reactions which might 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.

What she realized on the summit, she mentioned, 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 evident, performing 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 mentioned.
