Cal. Code Regs. tit. 23 § 3939.55
On December 8, 2016, the Regional Water Quality Control Board, Los Angeles Region (Los Angeles Water Board) adopted Resolution No. R16-010 to incorporate stakeholder-developed groundwater quality management measures for salts and nutrients in the Main San Gabriel Groundwater Basin of Los Angeles County. The State Water Resources Control Board approved the amendment under Resolution No. 2017-0030, on May 16, 2017.
Resolution No. R16-010 amends the Los Angeles Region's Basin Plan by incorporating stakeholder-developed groundwater quality management measures, contained in the Salt and Nutrient Management Plan (SNMP) for the Main San Gabriel Groundwater Basin in Los Angeles County, into Chapter 8 "Groundwater Quality Management -- Sustainability and Basin-specific Protection of Groundwater". The SNMP compiles existing salt and nutrient loading information for the Main San Gabriel Basin and uses existing water quality objectives established in Chapter 3 of the Los Angeles Region Basin Plan and current water quality information to determine available assimilative capacities to be used when evaluating the effectiveness of existing and potential salt and nutrient management measures as well as future water projects. The stakeholder-developed management strategies for salt and nutrients are designed to maintain water quality that is protective of beneficial uses, while increasing recycled water use and supporting the sustainable use of groundwater. These strategies will be applied in conjunction with already existing water quality protection measures in the planning area (e.g. cleanup operations).
