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. R3-2016-0003 on July 14,
					 2017, amending the
Water Quality Control Plan for the Central Coast
					 Region
(Basin Plan). The State Water Resources Control Board approved
					 the amendment under Resolution No. 2018-0013 on March 6, 2018. TMDLs are a
					 requirement of the federal Clean Water Act. Waterbodies assigned TMDLs by this
					 action include the Alisal Creek, Alisal Slough, Blanco Drain, Chualar Creek,
					 Espinosa Slough, Gabilan Creek, Merritt Ditch, Natividad Creek, Old Salinas
					 River, Quail Creek, Reclamation Canal, Salinas River (Lower), Tembladero
					 Slough, and other tributary surface waterbodies as identified in the Basin Plan
					 amendment.
The Central Coast Water Board's goal for establishing TMDLs
					 in the Lower Salinas River watershed is to rectify water quality impairments
					 related to toxicity and pesticides. The impairments are based on surface waters
					 not meeting the Basin Plan narrative water quality objectives for toxicity and
					 pesticides. Resolution No. R3-2016-0003 establishes total maximum daily loads
					 (TMDLs), numeric targets, and an implementation plan for sediment toxicity and
					 pyrethroid pesticides in sediment in the lower Salinas River watershed.
Responsibility for achieving pollutant load reductions
					 falls upon several entities as described in Attachment A to Resolution No.
					 R3-2016-0003 (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, as well as utilizing a Management Agency Agreement and pesticide
					 management plan between the California Department of Pesticide Regulation, the
					 State Water Resources Control Board, and the Central Coast Water Board to
					 address 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
					 13383.
