San Diego Regional Water Quality Control Board is a regional branch of the State Water Resources Control Board tasked with protecting and restoring surface water and groundwater quality within its designated region. It implements state and federal laws, develops basin plans, issues permits, and enforces water quality standards across urban, agricultural, and coastal areas. The Board interacts with municipalities, tribes, federal agencies, and international partners to address issues ranging from stormwater runoff to wastewater treatment and transboundary pollution.

Overview and Jurisdiction

The Board's jurisdiction encompasses coastal waters and watersheds in San Diego County, parts of Riverside County, and transboundary influences from Baja California. This jurisdiction overlaps with entities such as the United States Environmental Protection Agency, National Oceanic and Atmospheric Administration, and United States Navy installations along the Pacific Ocean coastline. Watershed areas under its purview include the San Diego River, San Luis Rey River, Sweetwater River, and the Tijuana River and estuary, where it coordinates with the International Boundary and Water Commission and Mexican federal agencies like the Comisión Nacional del Agua. The Board enforces provisions of the Clean Water Act and the Porter-Cologne Water Quality Control Act within its region.

History and Organizational Structure

The agency emerged from the state’s mid-20th century reorganization to implement the Federal Water Pollution Control Act Amendments of 1972 and subsequent environmental statutes. Its evolution reflects interactions with entities such as the California State Legislature, United States Congress, and the California Environmental Quality Act processes. Organizationally, the Board comprises an appointed board of members and a staff of engineers, scientists, and attorneys who coordinate with the California Coastal Commission, San Diego County Water Authority, and local city public works departments including City of San Diego Public Utilities Department. Legal and policy guidance often involves the California Attorney General and consultations with federal partners like the Department of the Interior and the United States Fish and Wildlife Service.

Programs and Regulatory Responsibilities

The Board administers National Pollutant Discharge Elimination System permits in concert with the United States Environmental Protection Agency, oversees municipal separate storm sewer systems for cities such as San Diego, Chula Vista, and Oceanside, and issues Waste Discharge Requirements for treatment plants including the Metro Wastewater Department and regional wastewater treatment facilities. It manages Total Maximum Daily Loads (TMDLs) established for impaired waters listed under the Clean Water Act section 303(d), coordinates wetland and riparian protection alongside the United States Army Corps of Engineers, and enforces requirements affecting agricultural operations, industrial sites, and military bases like Marine Corps Base Camp Pendleton. The Board’s regulatory portfolio intersects with programs by the California Department of Fish and Wildlife, California Department of Transportation, and regional air quality districts when multi-media issues arise.

Water Quality Planning and Basin Plans

Water quality planning is centralized in the Board’s regional basin plan documents, which set beneficial uses and water quality objectives for rivers, coastal waters, and aquifers. Basin plans are prepared under the oversight of the State Water Resources Control Board and incorporate scientific assessments from institutions such as the Scripps Institution of Oceanography, University of California, San Diego, and the San Diego State University. Planning processes consider impacts to protected areas including Torrey Pines State Natural Reserve, San Diego Bay National Wildlife Refuge, and the Tijuana Estuary National Estuarine Research Reserve. The Board’s basin plans guide permits, TMDLs, and restoration projects coordinated with the California Coastal Conservancy and regional flood control agencies like the San Diego County Flood Control District.

Enforcement and Compliance Actions

When violations occur, the Board can issue cleanup and abatement orders, administrative civil liability complaints, and refer matters for judicial action in coordination with the California Court System and the United States District Court for the Southern District of California. Enforcement actions have addressed discharges from wastewater treatment plants, illegal stormwater connections affecting beaches monitored by the California Beach Water Quality Monitoring Program, and cross-border sewage flows linked to infrastructure issues in Tijuana, Baja California. Compliance tools include monitoring programs developed with partners such as the Southern California Coastal Water Research Project and municipal utilities commissions.

Public Participation and Outreach

Public involvement in Board activities is facilitated through public meetings, notices, and collaborative forums with stakeholders including environmental organizations like the Surfrider Foundation, Sierra Club (United States), and local watershed groups such as the Tijuana River Valley Recovery Team. The Board engages tribal governments including the Kumeyaay and consults with the California Tribal Water Commission on projects affecting cultural resources. Outreach also involves coordination with school-based programs at institutions like the University of San Diego and community education efforts with county offices of education and non-governmental organizations.

Notable Projects and Partnerships

Significant initiatives include remediation and infrastructure projects addressing transboundary sewage pollution in the Tijuana River Valley, collaborative restoration of estuarine habitat with the United States Fish and Wildlife Service and the International Boundary and Water Commission, stormwater capture and reuse projects with the City of San Diego Public Utilities Department and the San Diego County Water Authority, and groundwater cleanup efforts linked to Superfund sites managed by the Environmental Protection Agency Region 9. The Board has partnered with research institutions such as Scripps Institution of Oceanography and San Diego State University on coastal monitoring, and with federal agencies including the National Oceanic and Atmospheric Administration and the United States Geological Survey for data sharing and technical support.
