§ 3006. Clear and Concise Summary of the Sediment Quality Provisions of the Water Quality Control Plan for Enclosed Bays and Estuaries of California Adopted by the State Water Resources Control Board on September 16, 2008 and Amended on April 6, 2011 and on June 5, 2018.
On September 16, 2008, the State Water Resources Control Board (State Water Board) adopted Resolution No. 2008-0070 approving Part 1 of the Water Quality Control Plan for Enclosed Bays and Estuaries of California (Part 1). Part 1 was amended by the State Water Board on April 6, 2011 (Resolution No. 2011-0017). Part 1 was amended by the State Water Board on June 5, 2018 (Resolution No. 2018-0028), which retitled Part 1 to “Sediment Quality Provisions.”
(a) As adopted on September 16, 2008, Part 1 includes two narrative sediment quality objectives and a program to implement the narrative objectives. The narrative objectives protect:
Benthic communities for direct exposure to pollutants in sediment, and
Human health from contaminants in fish tissue that bioaccumulate from the sediment up the food web
Part 1 describes how to interpret the narrative objectives and how to assess whether the narrative objectives have been attained. The program of implementation addresses:
Stressor identification studies
Monitoring ambient sediment quality
Use of the sediment quality objectives as receiving water limits in Waste Discharge Requirements/National Pollutant Discharge Elimination System Permits
Exceedance of receiving water limits
Applicability of the sediment quality objectives to dredging activities
Applicability of State Water Board Resolution No. 92-49 for cleanup actions and cleanup levels, and
Development of site-specific sediment management guidelines
(b) The amendments to Part 1, as adopted on April 6, 2011, modify the regulatory provisions of the previous Part 1 to include the following:
A narrative sediment quality objective that protects wildlife and resident finfish from both direct exposure to toxic pollutants in sediment and indirect exposure to pollutants in sediment that bioaccumulate up the food web
A requirement to utilize ecological risk assessment to implement this narrative
Additions to the glossary and supersession language to provide additional clarity
(c) The amendments adopted on June 5, 2018 include the following:
A revised approach implementing the aquatic life - benthic community protection sediment quality objective to assess multiple stations that encompass a site based upon magnitude of response and percent of area of impact, in order to evaluate the need to list waterbodies as impaired and evaluate compliance with receiving water limits
A revised approach implementing the sediment quality objective protecting human consumers from contaminants that bioaccumulate from sediment into tissue, applicable to organochlorine pesticides and polychlorinated biphenyls from sediment into sportfish
Additions to the glossary and supersession language to provide additional clarity
