The Environmental Protection Agency (EPA) Region 9 is publishing a direct final Notice of Deletion of the Sola Optical U.S.A., Inc. Superfund Site (Site), located in Petaluma, California, from the National Priorities List (NPL). The NPL, promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). This direct final deletion is being published by EPA with the concurrence of the State of California, through the California Regional Water Quality Control Board--San Francisco Bay Region, because EPA has determined that all appropriate response actions under CERCLA have been completed. However, this deletion does not preclude future actions under Superfund.
