California Code of Regulations › Title 23 - Waters › Division 4 - Regional Water Quality Control Boards › Chapter 1 - Water Quality Control Plans, Policies, and Guidelines › Article 6 - Lahontan Region › Section 3959.3 - Total Maximum Daily Load for Sediment in the Middle Truckee River Watershed, Placer, Nevada and Sierra Counties

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Water Board Resolution No. R6T-2008-0019, adopted on May
					 14, 2008 by the Lahontan Regional Water Quality Control Board, modified the
					 regulatory provisions of the Water Quality Control Plan for the Lahontan Region
					 by establishing a Total Maximum Daily Load (TMDL) for suspended sediment in the
					 middle Truckee River, including Gray and Bronco creeks. The middle Truckee
					 River is defined as the segment of the Truckee River from the outflow of Lake
					 Tahoe to the California-Nevada state line. On March 17, 2009, the State Water
					 Resources Control Board approved the amendment under Resolution No.
					 2009-0028.
The TMDL is a sediment control plan which sets a numeric
					 target for suspended sediment concentrations in the river, and includes
					 requirements for land managers to implement effective erosion controls to
					 reduce sediment delivery to the middle Truckee River by 20 percent. These
					 requirements will be included in Waste Discharge Requirements and Waivers as
					 appropriate. Continued monitoring will also be required to evaluate the
					 effectiveness of the TMDL. TMDL implementation is expected to result in
					 improving conditions such that the middle Truckee River will meet its water
					 quality standards for sediment within twenty years.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
On November 16, 2010, the Regional Water Quality Control
					 Board, Lahontan Region (Lahontan Water Board) adopted Resolution No.
					 R6T-2010-0058, amending the Water Quality Control Plan for the Lahontan Region.
					 The State Water Resources Control Board approved the amendment under State
					 Water Resources Control Board Resolution No. 2011-0022, on April 19,
					 2011.
Resolution No. R6T-2010-0058 establishes an amendment to
					 the Water Quality Control Plan for the Lahontan Region to incorporate a TMDL
					 and TMDL implementation plan for fine sediment particles, total nitrogen, and
					 total phosphorus for Lake Tahoe.
The TMDL is the sum of wasteload allocations for point
					 sources, load allocation for nonpoint sources, and a margin of safety in
					 protecting Lake Tahoe's deep water transparency. The major pollutant load
					 sources include: urban (developed) upland runoff, atmospheric deposition,
					 forest (undeveloped) upland runoff, and stream channel erosion. The most cost
					 effective and efficient load reduction options for the atmospheric deposition,
					 forested upland, and stream channel erosion sources are to continue with
					 existing programs. Because the most significant and quantifiable load reduction
					 opportunities are within the urban uplands source, the TMDL implementation plan
					 emphasizes actions to reduce fine sediment particle and associated nutrient
					 loading from urban stormwater runoff. Lahontan Water Board staff has developed
					 the tools and protocols to quantify, track, and account for pollutant loads
					 associated with urban runoff.
The Lahontan Water Board staff will evaluate progress
					 towards meeting the TMDL in periodic milestone reports and will annually track
					 actions taken to reduce loads from the major pollutant load sources. The
					 estimated timeframe to achieve the TMDL-required load reductions and meet the
					 numeric target is 65 years after the TMDL is approved by the US Environmental
					 Protection Agency. This requires that estimated fine sediment particle,
					 phosphorus, and nitrogen loads be reduced by 65 percent, 35 percent, and 10
					 percent, respectively.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
On December 7, 2011, the Regional Water Quality Control
					 Board, Lahontan Region (Lahontan Water Board) adopted Resolution No.
					 R6T-2011-0102, amending the Water Quality Control Plan for the Lahontan Region.
					 The State Water Resources Control Board approved the amendment under Resolution
					 No. 2012-0018, on May 15, 2012.
Resolution No. R6T-2011-0102 removes the former pesticide
					 Water Quality Objective, establishes a Waste Discharge Prohibition for
					 Pesticides and provides Exemption Criteria for the use of aquatic pesticides in
					 certain circumstances.
This amendment to the Lahontan Water Board's Basin Plan
					 replaces a regionwide pesticide water quality objective of non-detect, which
					 effectively prohibits pesticides in water, with a regionwide waste discharge
					 prohibition on discharges of pesticides with exemption criteria for aquatic
					 pesticide application. The amendment provides the Lahontan Water Board the
					 discretion to approve eligible aquatic pesticide applications. Eligible
					 projects include those proposed for purposes of public health and safety and
					 preservation of ecological integrity that satisfy exemption criteria. Examples
					 of projects that fit into these categories include vector control, fisheries
					 management, aquatic invasive species control and projects implemented for these
					 purposes in response to emergency situations. The Lahontan Water Board may
					 grant a prohibition exemption and regulate the subsequent aquatic pesticide
					 discharge under an applicable permit, such as Waste Discharge Requirements
					 (WDRs), a National Pollutant Discharge Elimination System (NPDES) permit, or a
					 waiver of WDRs issued by the State or Regional Water Board.

(3) a prohibition for discharge of silt-laden
				  tailwater into the Imperial Valley, including the Imperial Valley drains, New
				  River, and Alamo River.
A net reduction of about 51 percent of sediment/silt in the
					 Niland 2, P, and Pumice drains is required. The implementation plan requires
					 farm landowners, renters/lessees, and operators/growers to implement management
					 practices to reduce silt/sediment delivery into all drains that empty directly
					 into the Salton Sea, in accordance with a time schedule consisting of four
					 phases. Each phase consists of a two- or three-year period, with interim load
					 reductions for each phase. The first implementation provisions begin three
					 months after U.S. Environmental Protection Agency (USEPA) approval of the TMDL.
					 The implementation plan also requires the Imperial Irrigation District to
					 submit and maintain compliance with a revised Drain Water Quality Improvement
					 Plan, to begin six months after USEPA approval of the TMDL.
The prohibition begins three months after USEPA approval of
					 the TMDL and establishes that direct or indirect discharge of sediment will be
					 prohibited unless the discharger is in compliance with applicable
					 sedimentation/siltation TMDLs, has a monitoring program approved by the
					 Colorado River Basin Water Board's Executive Officer, or is covered by Waste

Resolution No. R7-2006-0047, adopted on June 21, 2006, by
					 the Colorado River Basin Regional Water Quality Control Board, modified the
					 regulatory provisions of the Water Quality Control Plan for the Colorado River
					 Basin Region by establishing a Total Maximum Daily Load (TMDL) and
					 Implementation Plan for trash in the New River at the International Boundary,
					 Imperial County, California. The current trash load of the New River is
					 impairing the following beneficial uses: warm freshwater habitat (WARM);
					 wildlife habitat (WILD); preservation or rare, threatened, and endangered
					 species (RARE); water contact recreation (REC 1); non-contact water recreation
					 (REC 2); and freshwater replenishment (FRSH). Water quality objectives are not
					 being met in the New River due in part to illegal dumping and littering into
					 the New River and its tributary drains in Mexicali, Mexico, which adversely
					 impacts beneficial uses. Trash has an impact on the water column that may
					 extend to the New River's terminus at the Salton Sea because trash may carry or
					 leach other pollutants (e.g., pathogens, VOCs, and metals), thus causing water
					 quality impacts.
The TMDL Implementation Plan consists of two phases, and
					 uses an interim numeric target to assess compliance progress. Phase I calls for
					 a 75 percent trash reduction within two years of United States Environmental
					 Protection Agency (USEPA) approval of the TMDL. Phase II calls for a 100
					 percent trash reduction within three years of USEPA approval of the TMDL. Third
					 party cooperating agencies are requested to complete implementation tasks
					 within specified timeframes, including signing a Memorandum of Understanding,
					 forming a coordination committee, and submitting semiannual progress
					 reports.

Resolution Order No. R7-2007-0039, adopted on May 16, 2007
					 and revisions adopted by Resolution Order No. R7-2010-0028 on June 17, 2010 by
					 the Colorado River Basin Regional Water Quality Control Board (Colorado River
					 Basin Water Board), modified the regulatory provisions of the Water Quality
					 Control Plan for the Colorado River Basin Region by establishing a Total
					 Maximum Daily Load (TMDL) and Implementation Plan for Bacterial Indicators in
					 the Coachella Valley Stormwater Channel. The State Water Resources Control
					 Board approved the amendments under Resolution No. 2011-0030, on July 19,
					 2011.
The TMDL addresses the impairment to water quality in the
					 Coachella Valley Stormwater Channel due to exceedences of bacteria water
					 quality objectives. The TMDL sets numeric targets for E. coli.
The implementation plan is divided into two phases with
					 Phase I actions being implemented within 90 days following U.S. Environmental
					 Protection Agency (U.S. EPA) approval of the TMDL. Phase I actions will take
					 three years to complete and will focus on monitoring and addressing bacteria
					 associated with wastewater discharges from facilities, urban runoff, and
					 stormwater runoff. If the water quality objectives are not achieved by the end
					 of Phase I, Colorado River Basin Water Board staff will implement additional
					 actions in Phase II to control pathogenic sources. Enforcement actions against
					 violators of the TMDL may be taken in Phases I and/or II, if necessary.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Colorado River Basin Regional Water Quality Control Board
					 (Regional Board) Resolution No. R7-2010-0011, adopted on May 20, 2010, by the
					 Regional Board, modified the regulatory provisions of the Water Quality Control
					 Plan for the Colorado River Basin Region (Basin Plan) by establishing a Total
					 Maximum Daily Load (TMDL) and Implementation Plan for Dissolved Oxygen (DO) in
					 the New River at the International Boundary (IB). The TMDL addresses DO
					 impairment in the New River due to wastewater entering California at the IB
					 with Mexico. The TMDL numeric target for DO is a minimum of 0.5 mg/L at any
					 time and applies to the first 12-mile segment of the New River downstream from
					 the IB. All publicly owned treatment works that discharge pollutants from point
					 sources in the impaired New River have been issued NPDES permits, which
					 prescribe TMDL allocations, as specified in the TMDL. The implementation plan
					 consists of two phases. Phase 1 requests that U.S. Environmental Protection
					 Agency (USEPA) and the U.S. Section of the International Boundary and Water
					 Commission (USIBWC) report measures taken to ensure Mexico's compliance with
					 the TMDL; continue to monitor water quality and DO in the New River at the IB;
					 and submit monitoring and progress reports to the Regional Water Board staff
					 according to the specified schedule. Phase 1 also requests that other
					 cooperating agencies with interests in New River water quality sign a
					 Memorandum of Understanding (MOU) to ensure coordination of IB projects. Phase
					 1 measures should be sufficient to achieve the New River DO water quality
					 objectives (WQOs). Phase 1 will be implemented in the first 3 years after USEPA
					 approves the TMDL. Phase 2 (the second 3 years after USEPA approval) will be
					 implemented if Phase 1 does not result in attaining the DO WQO. Regional Water
					 Board staff will track implementation and monitor water quality progress in
					 both phases, and will propose modification of the TMDL to the Regional Water
					 Board, if necessary, in phase 2.
