California Code of Regulations › Title 23 - Waters › Division 4 - Regional Water Quality Control Boards › Chapter 1 - Water Quality Control Plans, Policies, and Guidelines › Article 3 - Central Coast Region › Section 3929.11 - Basin Plan Amendment to Revise Onsite Wastewater System Requirements

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
On June 19, 2012, the State Water Resources Control Board
					 (State Water Board) adopted the
Water Quality Control Policy for
					 Siting, Design, Operation, and Maintenance of Onsite Wastewater Treatment
					 Systems
(OWTS Policy). The OWTS Policy provides criteria for siting,
					 design, operation and maintenance of onsite systems and provides a conditional
					 waiver for onsite systems that comply with the policy. The OWTS Policy is
					 available at the following link:
http://www.waterboards.ca.gov/water_issues/programs/owts/index.shtml
.
					 Applicable state-wide, the OWTS Policy designates regional boards with
					 principal responsibility for overseeing its implementation and calls for
					 incorporation of the OWTS Policy requirements into regions' basin plans within
					 a year of the policy's effective date.
At its May 30-31, 2013 meeting, the Central Coast Regional
					 Water Quality Control Board (Central Coast Water Board) adopted Resolution No.
					 R3-2013-0005 amending the
Water Quality Control Plan for the Central
					 Coastal Basin
(Basin Plan) to incorporate the OWTS Policy. This Basin
					 Plan amendment revises sections of the Basin Plan to delete redundant or
					 conflicting onsite wastewater systems criteria and incorporates by reference
					 the provisions of the OWTS Policy.
A clarifying paragraph is added to the existing Santa Cruz
					 County waste discharge prohibition to require the County of Santa Cruz to
					 submit a Local Agency Management Program and annual reports consistent with the
					 OWTS Policy
in lieu
of submitting annual reports under the
					 Wastewater Management Plan for the San Lorenzo River Watershed.
A paragraph that was inadvertently omitted from the current
					 Basin Plan is restored to the existing Los Osos/Baywood Park waste discharge
					 prohibition. The paragraph was originally adopted in 1983 by Resolution
					 R3-83-13 and pertains to consequences of failing to comply with (now-expired)
					 compliance dates.

California Code of Regulations › Title 23 - Waters › Division 4 - Regional Water Quality Control Boards › Chapter 1 - Water Quality Control Plans, Policies, and Guidelines › Article 3 - Central Coast Region › Section 3929.17 - Total Maximum Daily Loads for Nitrogen and Phosphorus Compounds in Streams of the Franklin Creek Watershed

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
The Central Coast Regional Water Quality Control Board
					 (Central Coast Water Board) adopted Resolution No. R3-2018-0006 on March 23,
					 2018, amending the
Water Quality Control Plan for the Central Coastal
					 Basin
(Basin Plan). The State Water Resources Control Board approved
					 the amendment under Resolution No. 2018-0049 on November 6, 2018. TMDLs are a
					 requirement of the federal Clean Water Act. Waterbodies assigned TMDLs by this
					 action include Franklin Creek and tributary surface waterbodies as identified
					 in the Basin Plan amendment.
The Central Coast Water Board's goal for establishing TMDLs
					 in the Franklin Creek watershed is to rectify water quality impairments related
					 to nitrogen and phosphorus compounds. The impairments are based on surface
					 waters not meeting the Basin Plan numeric water quality objective for drinking
					 water supply and the narrative water quality objective for biostimulatory
					 substances. Resolution No. R3-2018-0006 establishes total maximum daily loads
					 (TMDLs), numeric targets, and an implementation plan for nitrogen and
					 phosphorus compounds for streams in the Franklin Creek watershed.
Responsibility for achieving pollutant load reductions
					 falls upon several entities as described in Attachment A to Resolution No.
					 R3-2018-0006 (Basin Plan amendment). The Central Coast Water Board is relying
					 on existing regulatory measures (i.e., the Agricultural Order and stormwater
					 permits) to ensure implementation actions are carried out by implementing
					 parties to address the impairments.
Milestones are established for achieving the TMDLs and the
					 Central Coast Water Board will track progress towards achieving the TMDLs
					 through review of implementation actions and monitoring conducted by the
					 implementing parties. If existing efforts are not expected to achieve the TMDLs
					 as scheduled, the Executive Officer or the Water Board may require changes to
					 existing monitoring, reporting, or implementation efforts pursuant to
					 California Water Code Sections
					 13263,
					 13267 or

					 the Central Coastal Basin (Basin Plan) to establish Total Maximum Daily Loads
					 (TMDLs) for turbidity in the Gabilan Creek watershed, Monterey County. The
					 State Water Resources Control Board approved the Basin Plan amendment under
					 Resolution No. 2022-0023 on June 7, 2022.
TMDLs are a requirement of the federal Clean Water Act when
					 a waterbody is identified as not attaining applicable water quality standards.
					 Waterbodies assigned TMDLs by this action include Alisal Creek, Alisal Slough,
					 Espinosa Slough, Gabilan Creek, Merritt Ditch, Natividad Creek, Old Salinas
					 River, Salinas Reclamation Canal, Santa Rita Creek, and Tembladero
					 Slough.
Responsibility for achieving turbidity TMDLs falls upon
					 point source and nonpoint source responsible parties as described in the Basin
					 Plan amendment. The Central Coast Water Board will rely on existing regulatory
					 mechanisms (e.g., the Agricultural Order and stormwater permits), nonpoint
					 source implementation programs, and Basin Plan prohibitions for
					 implementation.
The Basin Plan amendment establishes milestones for
					 achieving the TMDLs, and the Central Coast Water Board will track progress
					 towards achieving the TMDLs through review of implementation actions and
					 monitoring conducted by the implementing parties. To ensure implementation
					 actions are carried out, the Basin Plan amendment establishes interim and final
					 implementation milestones of 7, 15, and 20 years for showing progress and
					 achieving the TMDLs. If existing efforts are not expected to achieve the TMDLs
					 as scheduled, the Executive Officer or the Central Coast Water Board may

Resolution No. 99-15, adopted on October 28, 1999 by the
					 Los Angeles Regional Water Quality Control Board (LARWQCB), modified the
					 regulatory provisions of the Water Quality Control Plan for the Los Angeles
					 Region by (1) revising the Table of Contents, (2) adding introductory text for
					 Chapter 7 (Total Maximum Daily Loads), and (3) establishing a Total Maximum
					 Daily Load (TMDL) for Trash for the East Fork of the San Gabriel River. The
					 TMDL addresses impairment to water quality due to trash being deposited in and
					 along the stream by recreational users. The TMDL sets a numeric target of no
					 trash in the river which implicitly incorporates a margin of safety, based on a
					 conservative interpretation of narrative water quality objectives. As the
					 responsible party, the U.S. Forest Service is assigned a load allocation of
					 zero trash discharged to the river. On May 25, 2000, the LARWQCB adopted
					 Resolution No. 00-10, which revised the implementation dates contained within
					 the TMDL. The U.S. Forest Service must submit a TMDL Implementation Plan within
					 60 days of the effective date of the amendment and begin implementation and
					 monitoring within 90 days of the effective date of the amendment. The U.S.
					 Forest Service must demonstrate compliance with the TMDL numeric target no
					 later than April 1, 2003.

California Code of Regulations › Title 23 - Waters › Division 4 - Regional Water Quality Control Boards › Chapter 1 - Water Quality Control Plans, Policies, and Guidelines › Article 4 - Los Angeles Region › Section 3939.1 - Update of Ammonia Objectives for Inland Surface Waters

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
The amendment revises the Basin Plan by updating the
					 ammonia water quality objectives for inland surface waters. The Basin Plan
					 objectives for ammonia are based on revised criteria developed by the U.S.
					 Environmental Protection Agency (USEPA) in the "1999 Update of Ambient Water
					 Quality Criteria for Ammonia." These most recent USEPA freshwater aquatic life
					 criteria for ammonia supercede previous criteria. The previous Basin Plan
					 one-hour average and four-day average objectives for waters designated as
					 "WARM" are retained for waters not characteristic of freshwater.
The ammonia objectives provide 1-hour average, 4-day
					 average, and 30-day average objectives for ammonia. The one-hour average
					 objective is dependent on pH and fish species (salmonids present or absent). It
					 is assumed that salmonids may be present in waters designated in the Basin Plan
					 as "COLD" or "MIGR" and that salmonids are absent in waters not designated in
					 the Basin Plan as "COLD" or "MIGR," in the absence of additional information to
					 the contrary. The 30-day average objective is dependent on pH and temperature.
					 At lower temperatures, the 30-day average objective also is dependent on the
					 presence or absence of early life stages of fish (ELS). Water bodies with a
					 Basin Plan designation of "SPWN" support high quality aquatic habitats suitable
					 for reproduction and early development of fish and, therefore, these water
					 bodies are designated as ELS present waters. The four-day average objective is
					 2.5 times the 30-day average objective.
The Basin Plan amendment also includes specific
					 implementation provisions for the objectives. These include methods for (1)
					 determination of freshwater, brackish water or salt water conditions; (2)
					 determination of presence or absence of salmonids when selecting the
					 appropriate one-hour average objective; (3) determination of presence or
					 absence of ELS when selecting the appropriate 30-day average objective; (4)
					 implementation of the objectives where more sensitive threatened or endangered
					 species are present; and (5) translation of objectives to effluent limitations
					 using a method similar to that in the "Policy for Implementation of Toxics
					 Standards for Inland Surface Waters, Enclosed Bays, and Estuaries of
					 California" (2000).

California Code of Regulations › Title 23 - Waters › Division 4 - Regional Water Quality Control Boards › Chapter 1 - Water Quality Control Plans, Policies, and Guidelines › Article 4 - Los Angeles Region › Section 3939.9 - Ammonia Objectives for Inland Surface Waters Not Characteristic of Freshwater

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
On March 4, 2004 the Los Angeles Regional Water Quality
					 Control Board (Regional Board), adopted Resolution No. 2004-022 amending the
					 Water Quality Control Plan for the Los Angeles Region (Basin Plan). The
					 amendment revised the Basin Plan by updating the ammonia objectives for inland
					 surface waters not characteristic of freshwater such that they are consistent
					 with the U.S. EPA "Ambient Water Quality Criteria for Ammonia
					 (Saltwater)-1989." The amendment revised the regulatory provisions of the Basin
					 Plan by adding language to Chapter 3 "Water Quality Objectives."
For inland surface waters not characteristic of freshwater,
					 the proposed objectives are a 4-day average concentration of un-ionized ammonia
					 of 0.035 mg/L and a one-hour average concentration of un-ionized ammonia of
					 0.233 mg/L. The proposed objectives are fixed concentrations of un-ionized
					 ammonia, independent of pH, temperature, or salinity. The proposed amendment
					 includes an implementation procedure to convert un-ionized ammonia objectives
					 to total ammonia effluent limits. The proposed amendment also simplifies the
					 implementation procedures for translating ammonia objectives into effluent
					 limits in situations where a mixing zone has been authorized by the Regional
					 Board. Finally, the proposed amendment revises the implementation procedure for
					 determining saltwater, brackish or freshwater conditions, to be consistent with
					 the proposed objectives. The proposed objectives will apply only to inland
					 surface waters not characteristic of freshwater (including enclosed bays,
					 estuaries and wetlands) and do not impact the Ammonia Water Quality Objectives
					 for ocean waters contained in the California Ocean Plan.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) The
				  Los Angeles Regional Water Quality Control Board (Regional Board) adopted under
				  Resolution Nos. 02-018 in October 2002, 03-008 on July 10, 2003, 04-004 on May
				  6, 2004, and revised under Resolution No. 06-016 on August 3, 2006 a Total
				  Maximum Daily Load (TMDL) for Chloride in the Upper Santa Clara River. The TMDL
				  specifies concentration-based targets for chloride and waste load allocations
				  for the Santa Clarita Valley Sanitation District (SCVSD) Saugus and Valencia
				  Water Reclamation Plants (WRPs), which must be fully attained 11 years after
				  the effective date of the TMDL. The August 6, 2006 revisions to the
				  implementation plan for the TMDL added tasks to begin the planning process to
				  construct appropriate treatment facilities at the WRPs to meet the TMDL. The
				  TMDL included subsequent tasks, such as development of site specific objectives
				  (SSOs), development of the antidegradation analysis, development of a
				  preplanning report on conceptual measures to meet different hypothetical final
				  waste load allocations, and preparation and consideration of a Basin Plan
				  Amendment to revise the chloride objective by the Regional Board.
(b) On December 11, 2008 the Regional Board
				  adopted Resolution No. 08-012, which modified the regulatory provisions of the
				  Water Quality Control Plan for the Los Angeles Region (Basin Plan) by:
(1) adopting SSOs for chloride in the upper
				  Santa Clara River (USCR), and
(2)
				  revising the USCR chloride TMDL.
(1) The chloride SSOs are based on the
				  results of special studies and an antidegradation analysis, as required by the
				  original TMDL. The revised USCR chloride TMDL sets numeric targets, conditional
				  waste load allocations, and an implementation plan based on the chloride SSOs.
				  The SSOs and revised TMDL allow for implementation of an alternative water
				  resources management (AWRM) program.
(2) The TMDL provided a ten-year schedule and
				  interim waste load allocations for chloride, as well as interim waste load
				  allocations for sulfate and total dissolved solids (TDS), to attain compliance
				  with the conditional SSOs and waste load allocations for chloride that support
				  the AWRM program. The conditional SSOs and waste load allocations apply and
				  supersede the regional water quality objectives only when chloride load
				  reductions and/or chloride export projects are operated. The implementation and
				  monitoring plan includes surface water and groundwater monitoring for chloride,
				  TDS, and sulfate.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) On
				  October 6, 2005, the Los Angeles Regional Water Quality Control Board (Regional
				  Water Board), adopted Resolution No. 2005-012, amending the Water Quality
				  Control Plan for the Los Angeles Region (Basin Plan). This Basin Plan amendment
				  established a Total Maximum Daily Load (TMDL) to reduce toxic pollutants in
				  Marina del Rey Harbor. The Basin Plan was amended again to modify the TMDL by
				  Resolution No. R14-004, adopted by the Regional Water Board on February 6,
				  2014. The State Water Resources Control Board approved the Basin Plan Amendment
				  on September 9, 2014 in Resolution No. 2014-0049. The TMDL:
(1) sets dual numeric targets for sediments
				  based on (A) the State's Water Quality Control Plan for Enclosed Bays and
				  Estuaries -- Part 1 Sediment Quality and (B) Effects Range-Low sediment quality
				  guidelines (ERLs) compiled by the National Oceanic and Atmospheric
				  Administration (the sediment target for total PCBs is based on a food web
				  bioaccumulation model rather than ERLs as this value is more protective of
				  human health);
(2) sets numeric
				  targets for the water column based on standards established by the California
				  Toxics Rule (CTR);
(3) sets numeric
				  targets for fish tissue based on the Office of Environmental Health Hazard
				  Assessment Fish Contaminant Goals;
(4) establishes a loading capacity to meet
				  numeric targets for sediment based on the average annual total suspended solids
				  loading to the harbor;
(5)
				  establishes a loading capacity for copper in the water column based on copper
				  leaching rates from boat hull paints; and
(6) allocates the loading capacities among
				  point and nonpoint sources of toxic pollutants.
