Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Los Angeles Regional Water Quality Control Board (Regional
					 Board) Resolution No. R2007-017, adopted on November 01, 2007 by the Regional
					 Board modified the regulatory provisions of the Water Quality Control Plan for
					 the Los Angeles Region (Basin Plan) by (1) revising the Table of Contents, (2)
					 adding introductory text for Chapter 7 (Total Maximum Daily Loads [TMDL]), and
					 (3) establishing a TMDL for Bacteria at Kiddie Beach and Hobie Beach.
Kiddie Beach and Hobie Beach in the Channel Islands Harbor
					 subwatershed in the Miscellaneous Ventura Coastal Management Area have been
					 listed under the federal Clean Water Act section
					 303(d) as not
					 attaining water quality standards due to elevated levels of indicator bacteria
					 and excess exceedances of bacteria numeric limits measured in ankle- to
					 knee-high depth. The beneficial uses most affected by elevated levels of
					 bacteria at the Kiddie and Hobie Beaches include water contact recreation
					 (REC-1) and non-contact water recreation (REC-2).
The amendment establishes waste load allocations (WLAs) for
					 point source discharges, load allocations (LAs) for nonpoint source discharges,
					 and interim allocations expressed as "allowable exceedance days". Allowable
					 exceedance days only apply to days in which single sample limits are exceeded
					 and does not apply to days where geometric mean limits are exceeded. Allowable
					 exceedance days are further separated into three separate time periods: summer
					 dry-weather, winter dry-weather, and wet-weather. The amendment establishes an
					 implementation schedule for complying with allocations with separate final
					 compliance dates of five years for dry-weather and ten years for wet-weather,
					 given the different conditions and implementation approaches necessary to
					 achieve compliance.
Responsible parties shall propose source control and Best
					 Management Practices (BMPs,) including but not limited to structural and
					 non-structural BMPs, at Kiddie Beach and Hobie Beach and subsequent
					 subwatershed during dry- and wet- weather for Executive Officer approval. Upon
					 approval, responsible parties shall implement source control and BMPs for
					 Kiddie Beach and Hobie Beach and subsequent subwatershed to address the
					 elevated levels of indicator bacteria. Agricultural dischargers in the
					 subwatershed are also required to submit a monitoring plan for Executive
					 Officer approval and implement monitoring six months after approval of the
					 plan.
In addition to a brief description of the Channel Islands
					 Harbor subwatershed and the existing conditions contributing to water quality
					 problems, the Basin Plan amendment also includes numeric targets, source
					 analysis, linkage analysis, WLAs, LAs, margin of safety, critical conditions,
					 implementation plan, and compliance schedules.
