California air quality regulators are doing the bare minimum to curb landfill pollution

I’ve learned that, while Val Verde’s situation is devastating, it’s unfortunately not unique. There are over 300 landfills across the state, and many — like Newby Island in Milpitas, Clover Flat Landfill in Calistoga and Avenal Landfill in Avenal — have also been in the news for making nearby residents sick. That’s because landfills emit health-harming pollutants like benzene, sulfur dioxide and volatile organic compounds. Like Val Verde, where nearly 60% of residents are Hispanic, communities of color are often the ones bearing the brunt of landfill pollution. It’s no coincidence that 70% of California’s highest-emitting landfills are located in these communities, a report by Industrious Labs found. Communities like mine are paying the price in doctor’s bills, in sick days, in missed school and in lives shortened by toxic exposure. CARB could make a meaningful difference right now by requiring stronger landfill cover practices, making sure that more landfill gas is collected before it escapes into our atmosphere, and using established technology to find invisible methane leaks. These aren’t radical solutions — they’re affordable, effective and ready to go. Watching the people I love suffer pushed me into activism. I had no choice. I began speaking out — not just in my neighborhood but to elected officials and policymakers across all levels of government. I even shared my story with the U.S. Environmental Protection Agency last year and testified in front of the air resources board earlier this year. Poor landfill management comes at a price, and communities across California have paid that price for too long. We’ve done our part — we’ve testified, we’ve suffered, we’ve waited. Now CARB needs to do its job and protect California communities.
California regulators haven't updated landfill pollution standards since 2010, and appear to be only doing the minimum in the latest effort to revisit them, argues an L.A. County activist impacted by the Chiquita Canyon Landfill.
