Current through Register 2024 Notice Reg. No. 28, July 12, 2024
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
