§ 3939.33. A Total Maximum Daily Load for Bacteria in the Harbor Beaches of Ventura County (Kiddie Beach and Hobie Beach).
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.
