State orders Chiquita Canyon Landfill to take corrective measures or face fines

A smoldering chemic absorption brewing heavy wrong the precocious closed Chiquita Canyon Landfill successful Castaic present threatens to devour an full 160-acre canyon of buried waste, endangering a retention country for hazardous liquid waste, according to authorities officials.

The California Environmental Protection Agency and authorities Department of Toxic Substances Control accidental the concern poses “an imminent and important danger” to nationalist wellness and the environment, and ordered the institution to instrumentality corrective measures oregon look fines of up to $70,000 daily.

The scorching-hot chemic absorption has been burning garbage heavy underground successful a 30-acre information of Chiquita Canyon Landfill for astir 3 years, causing noxious odors to drift into adjacent neighborhoods and hazardous leachate to spill onto the surface.

Although the landfill representatives person insisted the chemic absorption had mostly been contained to that 30-acre area, California biology regulators accidental there’s grounds that it has expanded to astir 90 acres, citing abnormally precocious temperatures and c monoxide emissions successful caller areas, according to a caller authorities investigation and enforcement action.

Without further action, authorities officials expect the absorption to proceed to turn and pain trash for a decennary oregon more.

“There is nary projected obstruction to forestall the absorption from consuming the full facility,” a March 28 CalRecycle study reads. “The absorption country is expanding, and the existent containment strategy has failed.”

Waste Connections Inc., the landfill proprietor and operator, disputed the state’s findings.

The institution “disagrees with a fig of statements and allegations made by immoderate of its regulators and the conclusions they are drafting from the data,” Steve Cassulo, the landfill manager, said successful a statement. “[Our staff] believes the information amusement that the mitigation efforts undertaken to day person had affirmative results to the stated extremity of slowing the reaction.”

According to authorities officials, immoderate parts of the landfill are rapidly collapsing arsenic ample amounts of buried discarded are burnt oregon interruption down. This includes an country underneath 1 of the landfill’s vessel farms — a postulation of retention containers utilized to store and dainty hazardous leachate. Deep cracks and sinkholes person besides formed connected the landfill’s aboveground adjacent these leachate retention containers.

State regulators interest that harm to the vessel workplace would origin chemical-laden leachate to spill onto the landfill’s aboveground and perchance into adjacent sources of water.

State agencies person ordered Waste Connections to relocate the vessel workplace to forestall hazardous chemicals from seeping into groundwater oregon spilling into tempest drains that provender into the Santa Clara River.

The leachate spills besides airs a menace to section aerial quality. When the scalding-hot leachate spills onto the surface, immoderate of the toxic chemicals tin evaporate, including benzene — a cancer-causing chemic recovered successful cigaret smoke. Some leachate samples contained benzene levels truthful precocious that they were considered hazardous discarded nether national standards.

Residents person phoned successful thousands of odor complaints to the South Coast Air Quality Management District. Many accidental they person experienced headaches, nosebleeds and trouble breathing.

State Assemblymember Pilar Schiavo (D-Chatsworth), who represents the neighboring communities of Val Verde and Castaic, petitioned for the authorities to state a authorities of emergency, underscoring the superior and long-lasting wellness risks from exposure. The Newsom medication denied the request, saying an exigency proclamation would not assistance effect efforts.

“The tanks wherever they’re treating the toxic liquid, the crushed is becoming unstable,” Schiavo said. “That’s conscionable an implicit nightmare situation. The leachate has truthful galore horrific chemicals that volition marque radical sick. And unfortunately, you know, I haven’t heard of a solution. There’s nary metallic slug for this benignant of situation.”

“How this is not 1 of the biggest disasters that we are each talking astir boggles my mind,” Schiavo added.

In the past, the utmost vigor from the absorption country has caused unit to physique up. Toxic leachate occasionally erupted and spilled onto the landfill’s surface. As a result, the landfill has been proactively extracting leachate to alleviate the pressure. Last year, astir 63 cardinal gallons of leachate were collected.

In summation to relocating the vessel farm, authorities regulators are besides requiring Waste Connections to instal a obstruction to forestall the chemic absorption from moving farther south. If the absorption spreads there, the vigor and instability could trigger a landslide, perchance blocking the main entranceway to the landfill.

The authorities besides is requiring the landfill to grow its synthetic screen strategy crossed the full main canyon to assistance suppress fumes.

“Enough is enough,” manager Katie Butler of the Department of Toxic Substances Control said successful a statement. “For excessively long, residents successful Val Verde and Castaic person suffered arsenic this biology situation worsens. And the landfill’s strategy is not working. This bid requires tangible actions to incorporate the absorption and trim impacts. DTSC volition enforce it to the fullest grade the instrumentality allows.”
