s 3949.2. Program to Control Dissolved Oxygen in the Stockton Deep Water Ship Channel.
Resolution No. R5-2005-0005, adopted by the Central Valley Regional Water Quality Control Board (Central Valley Water Board) on January 27, 2005, modified the regulatory provisions of the Water Quality Control Plan for the Sacramento and San Joaquin River Basins by incorporating a program for the control of factors contributing to the dissolved oxygen impairment in the Stockton Deep Water Ship Channel (DWSC). Impairment is defined in terms of excess net oxygen demand (ENOD) and responsibility for reducing ENOD is apportioned to the entities responsible for three factors that contribute to the impairment (low flow, increased channel geometry, and loads of oxygen demanding substances and their precursors (ODS)).
The program includes a Total Maximum Daily Load that allocates percent of relative responsibility for the ENOD to the point source and nonpoint source discharges that contribute ODS to the DWSC: 30 percent for a waste load allocation for the City of Stockton Regional Wastewater Control Facility; 60 percent for a load allocation for nonpoint sources (defined as discharges from irrigated lands); and 10 percent as a reserve for impacts from unknown sources and/or minor sources. An explicit margin of safety of 20 percent is incorporated. The Central Valley Water Board has committed to reviewing and updating the load allocations, waste load allocations, and prohibitions (mentioned below) by December 2009.
Entities responsible for sources of ODS are required to perform studies by December 2008 that identify and quantify: 1) sources of ODS in the source area; 2) growth or degradation mechanisms of ODS in transit to the DWSC; and 3) the impact of ODS on dissolved oxygen concentrations in the DWSC under a range of environmental conditions. Within 60 days from the effective date of this amendment, responsible entities must submit a study plan for the Central Valley Water Board describing how ongoing studies and future studies will address information needs.
Upon the effective date of this amendment, any increases in the discharge of ODS into waters tributary to the DWSC is prohibited unless the discharge is regulated by a waiver of waste discharge requirements, or individual or general waste discharge requirements or National Pollution Discharge Elimination System (NPDES) permits, which either implement the amendment or include a finding that the discharge will have no reasonable potential to cause or contribute to the dissolved oxygen impairment in the DWSC.
After December 31, 2011, the discharge of ODS into waters tributary to the DWSC is prohibited when net daily flow in the DWSC is less than 3,000 cubic feet per second, unless dissolved oxygen objectives in the DWSC are being met or the discharge is regulated by a waiver of waste discharge requirements, or individual or general waste discharge requirements or National Pollution Discharge Elimination System (NPDES) permits, which either implement the amendment; or include a finding that the discharge will have no reasonable potential to cause or contribute to the dissolved oxygen impairment in the DWSC.
The United States Army Corps of Engineers must submit by December 31, 2006 a technical report identifying and quantifying: 1) the chemical, biological, and physical mechanisms by which loads of substances into, or generated within the DWSC, are converted to oxygen demand; and 2) the impact that the Stockton Deep Water Ship Channel has on re-aeration and other mechanisms that affect dissolved oxygen concentrations in the water column.
Any project that requires a Clean Water Act Section 401 Water Quality Certification and that has the potential to impact dissolved oxygen conditions in the DWSC must evaluate and fully mitigate those impacts. The Central Valley Water Board may consider alternate measures, as opposed to direct control, of certain contributing factors if these measures adequately address the impact on the dissolved oxygen impairment and do not degrade water quality in any other way. Compliance with waste load allocations and load allocations for ODS, and development of alternate measures to address non-load related factors must be achieved by December 31, 2011.

Makes other minor clarifications and corrections in Basin Plan language.
s 3952. Removal of the Municipal and Domestic Supply (MUN) Beneficial Use Designations from Nine Saline Water Bodies.
On July 12, 2000, the Lahontan Regional Water Quality Control Board adopted Resolution No. 6-00-67 amending the Water Quality Control Plan for the Lahontan Basin (Basin Plan). The amendment revised the Basin Plan by removing the Municipal and Domestic Supply (MUN) beneficial use designations from nine saline water bodies. The water bodies include Wendel Hot Springs, Amedee Hot Springs, Fales Hot Springs, Hot Creek, Little Hot Creek, Little Alkali Lake, Keough Hot Springs, Deep Springs Lake, and Amargosa River.
The amendment removes the MUN designation of these waters from Table 2-1 in the Basin Plan, and also adds Amedee Hot Springs, Little Alkali Lake, and Little Hot Creek and their designated beneficial uses, with the exception of MUN, to Table 2-1. These three water bodies were previously categorized as "Minor Surface Waters" in the Basin Plan.
s 3953. Basin Plan Amendment Incorporating a Total Maximum Daily Load (TMDL) and TMDL Implementation Program to Control Sediment Loading to Heavenly Valley Creek.
The TMDL's goal of attaining instream standards is projected to occur within approximately 20 years after final approval of the TMDLs (2021).
The terms "parameter" and "desired conditions," as used in this TMDL, are equivalent to the U.S. EPA terms "indicator" and "targets," respectively, as defined in "Guidance for Developing TMDLs in California" January 7, 2000 USEPA, Region 09.
The TMDL assigns a loading capacity for total annual instream sediment loading to Heavenly Valley Creek, measured at the "Property Line" station near the resort permit boundaries, as 58 tons of sediment per year, expressed as a five year rolling average.
The TMDL implementation program is based substantially on continuation of existing erosion control and monitoring programs which are being carried out under an adaptive management approach by the U.S. Forest Service, Lake Tahoe Basin Management Unit (LTBMU - the landowner) and the Heavenly Valley Ski Resort (an LTBMU permittee).
The implementation program includes full application of Best Management Practices to all new and existing disturbed areas within the ski resort. Specifics of the implementation include the following:
Summary of TMDL Implementation Program
Implementation Measure Schedule
Abandon and restore 7.59 acres of existing Complete by 2006
unpaved roads
Stabilize 21.10 acres of existing roads which Complete by 2006
will remain in use
Restore 182 acres of existing ski runs Complete by 2006
Maintain BMPs as necessary Annually
Review success of specific BMPs at specific Annually
sites; identify and implement improvements
through adaptive management approach
Conduct a comprehensive review of progress At five year intervals
toward watershed restoration and attainment of beginning in 2000: (first
water quality standards and identify needs for evaluation report completed
change through adaptive management program. in 2001).
The Lahontan Regional Board will use its existing authority, including the Lake Tahoe Basin control measures outlined in Chapter 5 of its Basin Plan, and the three-tier compliance approach (ranging from voluntary compliance to regulatory action) in the statewide Nonpoint Source Management Plan, to ensure implementation of the TMDL.
The TMDL Implementation Plan includes the addition of macroinvertebrate community health monitoring, along with a continuation of monitoring provisions for suspended sediment concentration and flow and other parameters.
If progress is not satisfactory at the conclusion of the second (2005-2006) review, Regional Board staff will evaluate the need for revision of the TMDL and/or the implementation program.
s 3954. Revisions to the Water Quality Control Plan for the Lahontan Region, as Adopted by the California Regional Water Quality Control Board, Lahontan Region on January 23, 2002.
On July 12, 2000, the Lahontan Regional Water Quality Control Board (LRWQCB) adopted Resolution No. 6-00-66 amending the Water Quality Control Plan for the Lahontan Basin (Basin Plan). The amendments include both non-regulatory provisions (editorial and procedural changes) and regulatory provisions. The regulatory provisions of the amendments are:
(1) Revisions to a regionwide prohibition against discharges of industrial waste to surface waters. The amended language provides that discharges of "industrial process wastes," as defined, may be allowed to surface waters not designated for the Municipal and Domestic Supply (MUN) beneficial uses, if such discharges comply with General Discharge Limitations and appropriate findings under state and federal antidegradation regulations are made. The amendments also add definitions of "industrial process wastes," "municipal and domestic wastewater," and "industry."
(2) Removal of the potential Municipal and Domestic Supply (MUN) beneficial use designation from ground water within defined topographic boundaries surrounding Searles Lake, and addition of the Industrial Process Supply (PRO) use to ground water beneath the Searles Lake bed (Searles Valley ground water basin, Department of Water Resources Basin No. 52).
s 3955. Basin Plan Amendment Incorporating a Total Maximum Daily Load (TMDL) and TMDL Implementation Program to Control Phosphorus Loading to Indian Creek Reservoir.
The goal of this TMDL is a change from eutrophic to mesotrophic conditions, which should provide adequate support for aquatic life and recreational beneficial uses. Attainment of the numeric target for total phosphorus (0.02 mg/L as an annual mean concentration in the water column) is projected to occur within approximately 21 years after final approval of the TMDL (2024). Attainment of other numeric targets and narrative water quality objectives related to protection of beneficial uses is also projected to occur by that date.
The TMDL assigns a loading capacity for phosphorus loading to Indian Creek Reservoir, as a net annual load of 82 pounds of total phosphorus in the water column. Attainment of the loading capacity and numeric target will require an 87 percent reduction in internal phosphorus loading from the sediment and a 75 percent reduction in external loading to the reservoir from the surrounding watershed and the tributary inflow.
The TMDL implementation program will use an adaptive management approach. It establishes a process and schedule for selection and implementation of specific control measures. Such measures will include best management practices to control external sources, and in-lake control methods to control phosphorus loading from the sediment. Examples of potential in-lake controls include measures to remove phosphorus-laden sediment, reduce phosphorus release from sediment, and/or increase flushing of phosphorus from the reservoir. Implementation will be the responsibility of the South Tahoe Public Utility District (STPUD), which manages the reservoir and its tributary flow; the U.S. Bureau of Land Management, which owns the watershed contributing surface runoff to the reservoir; and public and private landowners in the watershed of the tributary inflow.
The Lahontan Regional Board will use its existing authority, including the three-tier compliance approach (ranging from self-determined implementation to regulatory action) in the statewide Nonpoint Source Management Plan and Rangeland Water Quality Management Plan, to ensure implementation of the TMDL.
The TMDL implementation program includes continued monitoring of water quality in the reservoir and its tributary inflow, and periodic inspection of BMPs once they have been installed. The adaptive management approach includes flexibility for changes in the existing monitoring program over time.
If progress toward implementation and attainment of TMDL targets and indicators is not satisfactory at the conclusion of the second comprehensive review (in 2013), or if monitoring shows support of beneficial uses at phosphorus concentrations higher than mandated by the target, Regional Board staff will evaluate the need for revision of the TMDL and/or the implementation program.
Specifics of the TMDL implementation program are as follows

s 3956. Basin Plan Amendment Revising Waste Discharge Prohibition Exemption Criteria for the Mojave Hydrologic Unit, San Bernardino County.
Exemptions to regionwide, hydrologic unit, and hydrologic area prohibitions may be granted as specified in Chapter 4.1 of the Water Quality Control Plan. Most exemptions are based on a finding by the Regional Board Executive Officer if so delegated, that the discharge will not result in exceeding the water quality objectives or unreasonably affect the water for its beneficial uses. The Lahontan Regional Water Quality Control Board (Regional Board) will base this determination on an analysis of the criteria contained in State Water Resources Control Board Resolution No. 68-16, the Statement of Policy with Respect to Maintaining High Quality Waters in California.
This amendment applies to the Mojave Hydrologic Unit for surface water that is tributary to the West Fork Mojave River or Deep Creek (Prohibition 1), the Silverwood Lake, Deep Creek, and Grass Valley watersheds (Prohibition 2), and surface waters upstream of the Lower Narrows (Prohibition 4). Language was added to Prohibitions 1 and 2 that exempts storm water discharges unless such discharges create a contition of pollution or nuisance. Prohibition 2 now applies to discharge of waste to land or water.
s 3957. Amendment to Designated Beneficial Uses.
On July 14, 2005, the Lahontan Regional Water Quality Control Board adopted Resolution No. R6T-2005-0021, amending the Water Quality Control Plan for the Lahontan Region (Basin Plan). The amendment revised Table 2-1 in Chapter 2 (Beneficial Uses) of the Basin Plan by deleting the Municipal and Domestic Supply (MUN) beneficial use designation for Owens Lake (Hydrologic Unit No. 603.30).
s 3960. Water Quality Control Plans.
The following are changes to regulatory provisions in the 1991 Water Quality Control Plan for the Colorado River Basin Region (Basin Plan). The surface water objectives for temperature, suspended solids, and settleable solids were changed by removing the words "point source". These objectives will now apply to nonpoint and point sources. The waiver for application of the bacteria objective was changed by adding the word "existing". Consequently, only existing point source discharges are now eligible for the waiver, while new point source discharges are not eligible. New language was added that contains numeric objectives for selenium (0.005 mg/L four-day average, 0.02 mg/L one-hour average) which apply to all surface water tributaries to the Salton Sea. Further, new language was added to address: 1. the regulation of sludge applications; 2. storm water pollution; 3. Regional Water Quality Control Board, Colorado River Basin Region's guidelines and the general permit for septic systems; and 4. the State Water Quality Certification Program.
s 3961. Establishment of a Total Maximum Daily Load for Sedimentation/Siltation for the Alamo River.
Regional Board Resolution No. 01-100, adopted on June 27, 2001, 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 (Basin Plan) by establishing a Total Maximum Daily Load (TMDL) for sedimentation/siltation in the Alamo River. The amendment to the Basin Plan requires the farmers/operators discharging agricultural return flows into the Alamo River and its tributary drains to implement best management practices to reduce silt/sediment delivery into the Alamo River, in accordance with a time schedule consisting of four phases. Each phase consists of about a three-year period with interim silt/sediment load reductions for each phase. Implementation of the TMDL does not take place until one year after the U.S. Environmental Protection Agency approves the TMDL. The amendment also requires the Imperial Irrigation District to submit and implement a revised drain water quality improvement plan, with a monitoring program, for the drains discharging into the Alamo River. A net reduction of 47% of the current sediment/silt load in the Alamo River is required by the TMDL.
s 3962. A Total Maximum Daily Load for Pathogens in the New River.
A Total Maximum Daily Load (TMDL) for pathogens discharged to the New River was adopted on October 10, 2001 by the Colorado River Basin Regional Water Quality Control Board (Regional Board). This resolution (No. 01-197) modified the Water Quality Control Plan for the Colorado River Basin Region. The U.S. Environmental Protection Agency (USEPA) must approve the TMDL.
The New River Pathogens TMDL specifies water quality objectives to protect the River's beneficial uses, which currently are impaired by high pathogen levels. Fecal coliforms, E. Coli and enterococci bacteria serve as pathogen indicators. The pathogens load is allocated among point and non-point sources in the New River sub-watershed. All U.S. wastewater treatment plants (WWTPs) within the sub-watershed must utilize disinfection equipment within 1 year of USEPA approval. TMDL objectives are to be achieved no later than 3 years after USEPA approval.
Regional Board staff is required to submit reports to the Regional Board that:
(1) Detail compliance with the implementation plan for the TMDL that specifies responsible parties and time schedules,
(2) Update financial options for implementation measures, and
(3) Detail implementation progress every six months.
The New River Pathogens TMDL will be re-evaluated and revised, if appropriate, based upon new monitoring data and studies.
s 3963. Establishment of a Total Maximum Daily Load for Sedimentation/Siltation for the New River.
Regional Board Resolution No. R-7-2002-0097, adopted on June 26, 2002, 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) for sedimentation/siltation in the New River. The implementation plan requires the farmers/operators in the New River Subwatershed to implement best management practices to reduce silt/sediment delivery into the New River, in accordance with a time schedule consisting of four phases. Each phase consists of about a three-year period, with interim load reductions for each phase. Implementation does not take place until one year after U.S. Environmental Protection Agency approval of the TMDL. It also requires the Imperial Irrigation District to submit and implement a revised drain water quality improvement plan, with a monitoring program, for the drains discharging into the New River. A net reduction of 17% of sediment/silt in the New River is required by the TMDL.
s 3964. Prohibition of the Discharge of Individual Subsurface Wastewater Disposal Systems in the Cathedral City Cove.
Regional Board Resolution No. 02-184 adopted on November 13, 2002 by the Colorado River Basin Regional Water Quality Control Board, amends the Water Quality Control Plan to prohibit discharges from individual subsurface wastewater disposal systems in Cathedral City Cove, pursuant to California Water Code s 13286. The prohibition takes effect on and after January 1, 2012. Cathedral City is required to submit to the Regional Board an implementation plan to comply with the January 1, 2012 prohibition date, one year following State Board approval of the subject amendment. Thereafter, the City is shall submit annual progress reports describing actions taken by the City or any other person or entity, to achieve compliance by January 1, 2012.
s 3965. Prohibition of Discharge from Septic Tanks on Parcels that Overlie the Mission Creek or the Desert Hot Springs Aquifers.
On March 30, 2004, the Colorado River Basin Regional Water Quality Control Board (Regional Board), adopted Resolution No. R7-2004-0017 amending the Water Quality Control Plan for the Colorado River Basin Region (Basin Plan). The amendment revised the Basin Plan by incorporate a prohibition of discharge of waste from existing or new individual disposal systems on percels of less than one-half acre that overlie the Mission Creek or the Desert Hot Springs aquifers if a sewer is available. The regulatory provisions are added to Chapter 4 of the Water Quality Control Plan.
Section 13281(b) of the California Water Code requires the Regional Board to prohibit the discharge of waste from individual disposal systems (or septic tanks) on parcels less than one-half acre that overly the Mission Creek or Desert Hot Springs Aquifers in Riverside County, California, if a sewer system is available within two hundred feet. For parcels of one-half acre or greater, septic systems are limited to two per acre if a sewer system is available, and discharge of waste from additional or existing septic systems is prohibited. This amendment implements this section of the California Water Code by incorporating this language into the Basin Plan and further requires the Mission Creek Water District to submit a report to the Regional Board describing actions taken to implement the subject prohibition.
s 3966. Total Maximum Daily Load for Sedimentation/Siltation for the Niland 2, P, and Pumice Imperial Valley Drains and Implementation Plan.
On January 19, 2005, the Colorado River Basin Regional Water Quality Control Board (Colorado River Basin Water Board) adopted Resolution No. R7-2005-0006 to modify the regulatory provisions of the Water Quality Control Plan for the Colorado River Basin Region by establishing: (1) a Total Maximum Daily Load (TMDL) for sedimentation/siltation in the Imperial Valley Drains: Niland 2, P, and Pumice Drains, and Implementation Plan, (2) an implementation plan for all Imperial Valley drains that empty directly into the Salton Sea, and (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 Discharge Requirements (WDRs) or a Waiver of WDRs.
s 3970. Exemption Criteria for Septic Systems Prohibition.

s 3972. "Revision of Bacterial Water Quality Objectives for Ocean Waters."
Regional Board Resolution No. 97-20, adopted on April 18, 1997, by the Santa Ana Regional Water Quality Control Board (SARWQCB), modified the regulatory provisions of the Water Quality Control Plan for the Santa Ana River Basin by deleting ocean water bacterial objectives for water contact recreation and shellfish harvesting and continuing to incorporate by reference the objectives contained in the Water Quality Control Plan for Ocean Waters (Ocean Plan).
s 3973. Establishment of a Total Maximum Daily Load for Sediment in the Newport Bay/San Diego Creek Watershed.
Regional Board Resolution 98-69, adopted on April 17, 1998, and Regional Board Resolution No. 98-101, adopted on October 9, 1998, by the Santa Ana Regional Water Quality Control Board (SARWQCB), modified the regulatory provisions of the Water Quality Control Plan for the Santa Ana Region by establishing a Total Maximum Daily Load (TMDL) for sediment discharged in the Newport Bay (Bay)/San Diego Creek watershed (Watershed). Phase 1 of the TMDL provides: (1) quantifiable targets for sediment deposition in Upper Newport Bay and the annual sediment load entering the Watershed; (2) load allocations for sediment discharged from specific land uses in the Watershed; (3) allowances for waivers of waste discharge requirements for maintenance dredging of flood control channels and for drainage channelization and stabilization projects under specified conditions; (4) requirements for sediment control measures to reduce dredging frequency of in-Bay sediment basins; and (5) maintenance requirements for in-channel and foothill sediment basins. Phase 2 of the TMDL provides specific monitoring requirements and methods for reassessment of the TMDL and specifies that required monitoring plans be approved by the SARWQCB at a duly noticed public hearing as per Chapter 1.5, Division 3, Title 23 of the California Code of Regulations (Section 647 et seq.).
s 3974. Establishment of a Total Maximum Daily Load for Nutrients in the Newport Bay/San Diego Creek Watershed.
Regional Board Resolution Nos. 98-09 and 98-100, adopted by the Santa Ana Regional Water Quality Control Board (SARWQCB) on April 17, 1998, and October 9, 1998, respectively, modified the regulatory provisions of the Water Quality Control Plan for the Santa Ana Region by establishing a total maximum daily load (TMDL) for nutrients (e.g.; nitrogen and phosphorous) discharged in the Newport Bay/San Diego Creek watershed (Watershed). The TMDL specifies daily, seasonal, and/or annual targets and specific land use load allocations for nutrients in the Watershed and total nitrogen load allocations for San Diego Creek (Reach 2). Phase 1 of the TMDL provides compliance schedules for: (1) review and revision of water quality objectives, (2) establishment of new waste discharge requirements, (3) revision of existing waste discharge requirements, (4) establishment of a nutrient management program for agricultural activities, and (5) co-permittees of the urban stormwater permit to submit: (a) an analysis of best management practices (BMPs) to achieve short-term (5-year) interim targets and final nutrient load reduction targets through the Drainage Area Management Plan (DAMP) and (b) a proposal for evaluating the effectiveness of implemented, control actions and compliance with nutrient load allocations. The sediment TMDL is incorporated by reference as the implementation plan for achieving the phosphorus loading reduction specified in the nutrient TMDL. Phase 2 of the TMDL provides specific monitoring requirements and methods for reassessment of the TMDL. Programs and activities required by the TMDL must be approved by the SARWQCB at a duly noticed public hearing as per Chapter 1.5, Division 3, Title 23 of the California Code of Regulations (Section 647 et seq.). These programs and activities are: (1) the agricultural nutrient management plan; (2) the proposal and analysis of BMPs to be implemented through the DAMP; and (3) the Phase 2 regional monitoring program.
s 3975. Establishment of a Total Maximum Daily Load for Fecal Coliform Bacteria in the Newport Bay.
Regional Board Resolution No. 99-10, adopted on April 9, 1999, by the Santa Ana Regional Water Quality Control Board (SARWQCB), modified the regulatory provisions of the Water Quality Control Plan for the Santa Ana Region by establishing a Total Maximum Daily Load (TMDL) for fecal coliform bacteria discharged in the Newport Bay. The TMDL addresses impairment due to pathogens in Newport Bay in a prioritized, phased approach. Compliance with objectives to protect water contact recreation are to be achieved no later than 14 years after State approval of the TMDL; objectives to protect shellfish harvesting are to be met no later than 20 years after State approval of the TMDL. Concentration-based allocations are assigned for vessel waste, urban runoff, natural sources, and agricultural runoff. The TMDL will be reevaluated and revised, if appropriate, based on monitoring results and relevant studies. These studies include source identification and characterization, development of a bacterial water quality model, a shellfish harvesting and a water contact recreation beneficial use assessment, and evaluation of a vessel waste program. Revision of the TMDL would be considered through the Basin Plan amendment process. Upon completion and consideration of studies and any appropriate Basin Plan amendment, the Regional Board shall adopt a plan for achieving the targets. This plan will use a phased compliance approach with priorities and compliance schedules assigned based on the use and area affected and the nature, magnitude, and timing of violations. The fecal coliform TMDL contains an implicitly incorporated margin of safety by not applying adjustments for dilution, natural die-off, and tidal flushing.
s 3976. Basin Plan Amendment Authorizing Schedules of Compliance in NPDES Permits.
On May 19, 2000, the Santa Ana Regional Water Quality Control Board (Santa Ana Regional Board) adopted Resolution No. 00-27 amending the Basin Plan to incorporate language that explicitly authorizes the Santa Ana Regional Board to include schedules of compliance in National Pollutant Discharge Elimination System permits for effluent limitations that implement water quality objectives or criteria that are adopted, revised, or newly interpreted after this Basin Plan amendment becomes effective. The amendment requires that dischargers requesting such a schedule(s) of compliance submit documentation that is to be justified and as short as possible. The amendment identifies the minimum documentation that is to be submitted and stipulates that the Santa Ana Regional Board may require additional documentation on a case-by-case basis. The amendment also stipulates that any approved compliance schedule shall not exceed ten years from the date of adoption or interpretation of the applicable water quality objective or criterion.
s 3977. Resolution No. R8-2003-0039 - Amending the Water Quality Control Plan (Basin Plan) for the Santa Ana Region To Include a Total Maximum Daily Load (TMDL) for Chlorpyrifos and Diazinon in San Diego Creek and Upper Newport Bay.Regional Board Resolution No. R8-2003-0039, adopted on April 4, 2003 by the Santa Ana Regional Water Quality Control Board, modified the regulatory provisions of the Water Quality Control Plan [Basin Plan] for the Santa Ana Region by establishing a TMDL for chlorpyrifos in Upper Newport Bay and diazinon and chlorpyrifos in San Diego Creek.
