SITE CLEANUP PROGRAM (SCP)

Formerly Spills, Leaks, Investigations and Cleanups (SLIC)

The objectives of the Los Angeles Regional Water Quality Control Board's site cleanup program are to protect and restore water resources, and to uphold stringent goals to protect human health, water quality and the environment, today and into the future.

The Site Cleanup Program (SCP) regulates and oversees the investigation and cleanup of unauthorized discharges of pollutants and pollution-impaired sites not overseen by the Underground Tank Program. The primary goal of the SCP is to direct and provide oversight of site investigation and cleanup activities that will result in restoration and/or protection of water quality, human health, and the environment.

The scope of the SCP is not restricted to particular pollutants or environments; it covers all types of pollutants, such as solvents, petroleum fuels, and heavy metals, and all environments, including surface water, groundwater, and the vadose zone (also known as the unsaturated zone extending from the top of the ground surface to the water table).

Upon confirmation that an unauthorized discharge is polluting or threatening to pollute regional water bodies, the Los Angeles Regional Water Quality Control Board (Regional Water Board) has the legal and regulatory authority to oversee site investigations and direct corrective actions. The California Water Code provides authority for the State Water Resources Control Board and the Regional Water Boards to require investigation and cleanup of sites with unauthorized pollutant releases.

• The five essential elements of site investigation and cleanup are:

  • Preliminary site assessment to confirm the discharge and the identity of the dischargers; to identify affected or threatened waters of the state and their beneficial uses; and to develop preliminary information on the nature and vertical and horizontal extent, of the discharge;

  • Soil and water investigation to determine the source, nature, and extent of the discharge with sufficient detail to provide the basis for decisions regarding subsequent clean-up and abatement actions, if any, are determined by the Regional Water Board to be necessary;

  • Proposal and selection of clean-up action to evaluate feasible and effective cleanup and abatement actions and to develop preferred cleanup and abatement alternatives;

  • Implementation of clean-up and abatement action to apply the selected alternative and to monitor in order to verify progress; and

  • Monitoring to confirm short and long-term effectiveness of the cleanup and abatement.

• The SCP generally provides oversight for sites and projects involving:

  • Cost Recovery (CR) agreements: Pursuant to Porter-Cologne, Section 13304, reasonable costs for such oversight can be recovered by the Regional Water Board) from the responsible party. Before any oversight work can be done, the responsible party or parties must agree to reimburse the State for costs associated with the investigation and cleanup. Any overhead charges are based on the number of labor hours charged and can consist of rent, travel, training, supplies, and personnel services. If there is no labor charged, there will be no overhead charges. No cleanup oversight will be performed unless the responsible party in question agrees in writing to reimburse the State for appropriate cleanup oversight costs.

  • Superfund designation, in conjunction with the United States Environmental Protection Agency (USEPA): Since 1980, the USEPA has collaborated with state and local agencies such as this Regional Water Board to protect human and environmental health by managing the cleanup of the most contaminated hazardous waste sites in the United States, known as Superfund Sites. Sites determined to have superfund designation are added to the National Priorities List until cleanup has been completed. A tool for finding current Superfund and Brownfields cleanup projects in California can be found at: https://www.epa.gov/cleanups/cleanups-my-community.

  • Redevelopment: The Regional Water Board manages cleanup of sites where use or expansion is complicated by environmental contamination, either real or perceived. These sites will be further developed, expanded, or redeveloped for continued or future use after the cleanups have been completed.

  • Department of Defense (DOD): Decades of defense activities have degraded water quality on and around federally-owned facilities. Working with other agencies, the Regional Water Board is involved with remedial investigation and cleanup actions on more than 16 U.S. Department of Defense (DOD) sites. Agreements with the DOD provide for accelerated cleanups at military bases and other Defense sites scheduled for closure and reuse. Site investigation and cleanup procedures are consistent with State laws and regulations as well as applicable provisions of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Additional information can be found at: www.waterboards.ca.gov/water_issues/programs/dept_of_defense.

  • The Above Ground Tank (AGT) Program: Effective January 1, 2008, the Regional Water Board no longer oversees the AGT Program. Certified Unified Program Agencies (CUPA's) are vested with the responsibility and authority to implement the Aboveground Petroleum Storage Act (APSA). Additional Information can be found by visiting http://www.calepa.ca.gov/CUPA/Aboveground/.

  • The Former Well Investigation Program: The Regional Water Board managed specific investigations into sites potentially impacting drinking water wells. While this program is no longer active, information from the WIP database can be found in the existing GeoTracker database: https://geotracker.waterboards.ca.gov/.

  The GeoTracker database (Former SCP database) is the Water Boards' data management system for sites that impact, or have the potential to impact, water quality in California, with an emphasis on groundwater: GeoTracker contains records for sites that require cleanup, such as Leaking Underground Storage Tank (LUST) Sites, Department of Defense Sites, and Cleanup Program Sites. GeoTracker also contains records for various unregulated projects as well as permitted facilities including Irrigated Lands, Oil and Gas production, operating permitted underground storage tanks (USTs), and Land Disposal Sites. To review any files stored on this list, please email a request to: RB4-PublicRecords@waterboards.ca.gov.

  The Regional Water Board works closely with the Department of Toxic Substances Control (DTSC). DTSC's EnviroStor Database allows for quick access to vital information about environmental cleanups and permitted facilities in communities. To view a list of DTSC sites, please visit: http://www.envirostor.dtsc.ca.gov/public/.

• Public Participation

  Sections 13307.5 and 13307.6 of the California Water Code mandate public participation activities for sites under cleanup and abatement orders (CAOs), and public participation is an integral component of the Site Cleanup Program. The Regional Water Board engages in community outreach, engagement and education, provides timely and ongoing communication, and encourages public comment on Board actions and activities. The level of public participation at cleanup sites is based on potential dangers to human health and water quality, the degree of public interest, and environmental justice concerns.
