SAN FRANCISCO — California Attorney General Kamala Harris is suing ConocoPhillips and its spinoff, Phillips 66, over underground tanks used to store gasoline at more than 500 gas stations in the state.
Harris alleges the companies have tampered with or disabled leak detection devices and failed to properly inspect and maintain the tanks since November 2006.
Harris accuses the companies of violating state laws intended to protect residents from contaminated groundwater.
Her civil lawsuit was filed on Wednesday in Alameda County. She was joined by district attorneys from numerous counties in the state.
