State lawmakers are planning an oversight hearing that will look into how California handles toxic soil from old industrial, military and other cleanup sites — waste contaminated with things such as lead, petroleum hydrocarbons and the infamous insecticide DDT.
A CalMatters investigation last month revealed businesses and government agencies routinely dispose of contaminated soil at landfills in Arizona and Utah — states with weaker environmental regulation and oversight — as opposed to in California where the waste would need to go to specialized hazardous waste disposal facilities.
Two of the most heavily used landfills are near Native American reservations in Arizona, including one landfill with a spotty environmental record.
California state and local government agencies largely oversee or directly manage the cleanup projects disposing the waste out of state. California’s own hazardous waste watchdog — the Department of Toxic Substances Control — is one of the biggest out-of-state dumpers and has continued to take its toxic waste to Arizona despite the public revelations, according to information the department recently provided.
