4 TMDL for indicator bacteria in the Santa Clara River Estuary and Reaches 3, 5, 6, and 7 This TMDL for indicator bacteria in the impaired sections of the Santa Clara River watershed to address impairments of water contact recreation and non contact recreation beneficial uses. Implemented through General and Individual NPDES permits, MS4 permits, Industrial and Construction Stormwater permits, the Caltrans Stormwater permit, the Conditional Waiver for Irrigated Lands, WDRs, waivers of WDRs and other appropriate mechanisms. 07-08-2010 0 12
4 Santa Monica Bay Nearshore and Offshore Debris TMDL TMDL for Debris in the Santa Monica Bay to address impairments of aquatic life, wildlife, and recreational beneficial uses. Waste load allocations for trash will be implemented through the MS4 permit. Implementation for plastic pellets through the Industrial Stormwater permit. Load allocations for non-point sources of trash implemented in a manner consistent with the Statewide Policy for Implementation and Enforcement of the Nonpoint Source Pollution Control Program. 11-04-2010 0 3
6 Lake Tahoe TMDL TMDL for fine sediment and nutrients from urban stormwater, forested uplands, atmospheric deposition and stream channel erosion to attain clarity objective within 65 years. Implementation through stormwater NPDES permits, BMPs for activities on undeveloped forested lands, stream restoration projects, ongoing air quality and transportation control programs, tracking of implementation actions and water quality and air quality monitoring. 11-06-2010 0 13


Other Basin Planning Amendments Adopted by Regional Boards in Fiscal Year 2010/2011
Region Title Description Adoption Date Objectives (Count) Imple-mentation (Count)
2 Beneficial Use Update Adds 275 water bodies to Basin Plan and makes 2,327 changes additions and 104 changes to the designated beneficial uses for the newly added and existing water bodies. 07-14-2011 0 0
4 REC-1 Freshwater Bacteria Objectives Update Removal of the fecal coliform objectives for freshwaters designated for water contact recreation. Updates the freshwater bacteria objectives in the Basin Plan to maintain consistency with EPA's recommendation that E.coli replace fecal coliform as an indicator of the presence of pathogens in freshwater. 07-08-2010 2 0
7 Implementation Plan for Ag Wastewater Discharges Originating within the Palo Verde Valley and the Palo Verde Mesa Prohibition of agricultural wastewater discharges that originate within the Palo Verde Valley and Palo Verde mesa 01-20-2011 2 4
7 Yucca Valley Septic Tank Discharge prohibition 3-phase project that prohibits waste septic systems in specific areas in the Town of Yucca Valley (Town), San Bernardino County, CA 05-19-2011 2 2
7 Basin Plan Update - Non Regulatory Nonregulatory amendment to correct or updates language, tables and figures contained in the current Basin Plan. 01-20-2011 0 0
8 Total Dissolved Solids and Nitrate-Nitrogen Water Quality Objectives for the San Jacinto Upper Pressure Management Zone This Basin Plan amendment establishes a second set of TDS and nitrate-nitrogen objectives for the San Jacinto Upper Pressure Management Zone. This second, less stringent set of objectives is based on the finding that water quality consistent with “maximum benefit to the people of the State” will be maintained (the “maximum benefit” objectives), provided that specific water and wastewater projects and programs are implemented by Eastern Municipal Water District. 10-29-2010 2 7
9 Definition of Commercial Growing Operation in Conditional Waiver No. 4 for Agricultural and Nursery Operations
(Resolution No. R9-2011-0020)
Amendment adds a definition of “commercial agricultural and nursery operations” to Conditional Waiver No. 4. 02-09-2011 0 0
9 2011 Basin Plan Triennial Review (Resolution No. R9-2011-0047) Resolution adopts the 2011 Basin Plan Triennial Review. 06-08-2011 0 0



In Fiscal Year 20010-11, the Regional Water Boards adopted amendments to the Water Quality Control Plan (Basin Plan) though 14 separate resolutions. The tables above provides a summary of the amendments that were adopted by each region with information about what each set of amendments is intended to do. Nearly half (6) of the resolutions were to adopt TMDLs. Three of the resolutions adopted amendments to regulatory programs, and three resolutions primarily included updates to designated beneficial uses or water quality objectives. In one case, amendments were adopted to simply clarify and update the basin plan without making substantive regulatory changes. Each set of amendments includes numerous implementation tools that will be used to implement these regulatory changes, primarily with most involving one or more changes to permitting and monitoring programs.



Basin Plans are the Water Boards primary water quality planning documents. Basin Plans designate beneficial uses for waters of the state, water quality objectives designed to protect those uses, and establish implementation plans to achieve the water quality objectives. Basin Plans are living documents that are regularly updated to meet changing needs. They serve as the principal basis for waste discharge requirements (permits) issued and cleanup requirements established by the Water Boards, and also are used by outside agencies in their permitting and resource management activities. The Regional Water Boards review and revise their Basin Plans periodically to address new information and changes in policy.
