Document Description
Cont. Title: Franklin Creek Watershed The Central Coast Regional Water Quality Control Board (Central Coast Water Board) adopted this Basin Plan amendment via Resolution No. R3-2018-0006 on March 23, 2018. The State Water Resources Control Board approved the amendment through Resolution No. 2018-0049 on November 6, 2018. Total maximum daily loads (TMDLs) are a requirement of the federal Clean Water Act. Waterbodies assigned TMDLs by this action include Franklin Creek and other 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 pbosphorus 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 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 Water Board may require changes to existing monitoring, reporting, or implementation efforts pursuant to California Water Code Sections 13263, 13267 or 13383.
