Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
				Resolution 99-065, adopted June 17, 1999, by the State Water Resources Control
				Board, created the Consolidated Toxic Hot Spots Cleanup Plan (Plan). As
				required by Water Code Sections
				13392 and
				13394, the Plan
				requires the Regional Water Quality Control Boards to implement remedial
				actions at identified known toxic hot spots to improve and protect the quality
				of the enclosed bays, estuaries and coastal waters of the State from discharges
				of hazardous substances in accordance with the provisions of Chapter 5.6 of the
				Water Code. The Plan was adopted as Policy for Water Quality Control. The Plan
				contains the following elements:
* A list of known toxic hot spots;
* The priority of each known toxic hot spot;
* Procedures for removing toxic hot spots from the
				  Plan;
* Guidance on the reevaluation of waste discharge
				  requirements;
* The scope of remedial actions and costs;
* Policy on remediation if potential discharger is
				  identified;
* Policy on remediation in the absence of potential
				  discharger;
* Policy for prevention of toxic hot spots:
* Special provisions for remediation in San Diego Bay;
* The toxic hot spot definition, ranking criteria, and
				  benefits of remediation;
* Mitigation necessary to avoid the potential environmental
				  impacts of remediation; and
* Regional Toxic Hot Spots Cleanup Plan developed pursuant to
				  Title 23, California Code of Regulations Section
				  2912.
(b) On January 22, 2004, the State Water
				Resources Control Board (State Water Board) adopted Resolution No. 2004-0002
				amending the Consolidated Hotspots Cleanup Plan (Consolidated Plan). The
				amendment revised three toxic hot spot cleanup plans for the Central Valley
				region.
The Central Valley Regional Water Quality Control Board
				  (Regional Water Board) adopted the revised plans in Resolution R5-2003-0034.
				  The revised plans address:
1) diazinon
				in orchard dormant spray;
2)
				diazinon and chlorpyrifos in stormwater; and
3) chlorpyrifos in irrigation return flow.
				The revisions deleted site-specific variances for these hot spots and added
				specific information addressing the elements that must be included in a toxic
				hot spot cleanup plan under Water Code §
										13394. The
				revised Plans recognize that the three pesticide problems are seasonal water
				column problems that cannot be addressed by hauling away the water or
				underlying sediments but instead must rely on controlling the amount of
				chemicals that reach surface waters in the delta. The revised Plans:
* Comprehensively describe actions already implemented to
				  reduce pesticide levels (Water Code §
											13394(h))
* Preliminarily assess actions required to remedy or restore
				  toxic hot spots (Water Code §
											13394(f)),
				  including the establishment of time schedules for the Regional Board to
				  consider Basin Plan amendments to control pesticide discharges and to implement
				  TMDLs, as well as the identification of elements that need to be included in
				  revisions to the Basin Plan
* Estimate the costs of implementing the program and the
				  costs that may be recoverable from potential dischargers (Water Code
				  §§
											13394(c) and
				  (e)) and identify potential sources of funds
				  for costs not recoverable from dischargers (Water Code §
											13394(g))
* Require monitoring to evaluate program
				  success.
