For Immediate Release  
Attorney General Kamala D. Harris Sues Phillips 66 and ConocoPhillips over 
Environmental Violations at Gas Stations                                         
SAN FRANCISCO -- Attorney General Kamala D. Harris today filed a civil lawsuit 
against Phillips 66 and ConocoPhillips for allegedly violating state law by 
failing to properly inspect and maintain underground tanks used to store 
gasoline for retail sale at more than 560 gas stations in California. 
“The state’s hazardous waste laws help protect our residents from contaminated 
groundwater,” Attorney General Harris said. “This lawsuit safeguards public 
health by ensuring proper maintenance of the tanks that store fuel beneath many 
California communities.” 
The Attorney General’s office was joined in this enforcement action by Alameda 
County District Attorney Nancy E. O’Malley, El Dorado County District Attorney 
Vern Pierson, Merced County District Attorney Larry D. Morse II, Nevada County 
District Attorney Clifford Newell, Placer County District Attorney R. Scott 
Owens, San Bernardino County District Attorney Michael A. Ramos, and Stanislaus 
County District Attorney Birgit Fladager. 
The complaint filed today in Alameda County Superior Court alleges that, since 
November 2006, Phillips 66 and ConocoPhillips have improperly monitored, 
inspected and maintained underground storage tanks used to store gasoline for 
retail sale. The complaint alleges that the defendants tampered with or 
disabled leak detection devices, and failed to test secondary containment 
systems, conduct monthly inspections, train employees in proper protocol, and 
maintain operational alarm systems, among other violations. The lawsuit also 
alleges that the defendants improperly handled and disposed of hazardous wastes 
and materials associated with the underground storage tanks at retail gas 
stations throughout the state.   
A statewide investigation led by the Attorney General’s office found violations 
of hazardous materials and hazardous waste laws and regulations at gas stations 
in 34 counties across the state. 
Deputy Attorney Generals Brett J. Morris and Deborah Halberstadt are 
prosecuting the case for Attorney General Harris’ Environment Section.
