Temperature Policy Amendment

Amendment to the Water Quality Control Plan for the North Coast Region to Establish a Policy for the Implementation of Temperature Objectives and Establish Implementation Plans for the Eel, Mattole, and Navarro TMDLs


North Coast Regional Water Quality Control Board (Regional Water Board) staff is proposing Basin Plan revisions that will add a policy to implement the water quality objective for temperature. The amendment will also add additional action plans to implement total maximum daily loads for temperature in the Navarro, Eel, and Mattole watersheds. The proposed revisions to the Basin Plan include changes to Chapter 4 - Implementation Plans.

Note: The Regional Water Board directed staff to prepare an amendment incorporating a temperature implementation policy into the Basin Plan by adoption of resolution R1-2012-0013.

The proposed Basin Plan amendment will describe the approach to implementing the interstate water quality objective for temperature in one cohesive policy. It will identify the regulatory mechanisms staff will employ to ensure achievement of the water quality objective for temperature, it will describe the significance of stream shade as a factor determining stream temperatures, and it will direct staff to address temperature concerns through existing authorities and processes.

The proposed Basin Plan amendment will also establish implementation plans for the Navarro, Mattole, Upper Main Eel, Middle Main Eel, Lower Eel, Middle Fork Eel, North Fork Eel, and South Fork Eel River temperature total maximum daily loads.

The Regional Water Board considered the Policy and Action Plans at a public hearing during the Regional Water Board's November 20, 2013 meeting in Santa Rosa, California. The Regional Water Board deferred action at that time and directed staff to define the term "site potential effective shade" and clarify the concept, with particular discussion of how the concept is applied and assessed. Staff have developed additional material in response to the Regional Water Board's direction, which are now available for review.
