Current through Register 2024 Notice Reg. No. 28, July 12, 2024
This Basin Plan amendment establishes a Total Maximum Daily
					 Load (TMDL) for bacteria in Malibu Creek and Lagoon for summer (April 1 to
					 October 31) dry weather, winter (November 1 to March 31) dry weather and
					 wet-weather days. Wet-weather days are defined as any day receiving 0.1 inch of
					 rain or more and three days thereafter. The TMDL establishes the loading
					 capacity of the Malibu Creek and Lagoon as the maximum densities of the four
					 bacterial indicators (total coliform,
E. coli
, fecal coliform,
					 and enterococcus) as specified in the Basin Plan as bacteriological water
					 quality objectives for fresh and marine water having a water contact beneficial
					 use designation. This TMDL will be implemented in two phases over a
					 fifteen-year period. By January 24, 2012, compliance with the allowable number
					 of dry-weather exceedance days must be achieved. By July 15, 2021, compliance
					 with the allowable number of wet-weather exceedance days and rolling geometric
					 mean targets must be achieved.
The regulatory mechanisms to implement the TMDL may
					 include, but are not limited to, the Los Angeles County Municipal Separate
					 Storm Sewer System (MS4) National Pollutant Discharge Elimination System
					 (NPDES) Permit, Ventura County MS4 NPDES Permit, the Caltrans Storm Water
					 Permit, any future Phase II MS4 permits, waste discharge requirements (WDRs),
					 Memorandum of Understanding (MOUs), revised MOUs, or other appropriate
					 mechanisms consistent with the Nonpoint Source Implementation and Enforcement
					 Policy, general NPDES permits, general industrial storm water permits, general
					 construction storm water permits, and the authority contained in Sections
					 13225,
					 13263,
					 13267, and
					 13383 of the
					 California Water Code, and other appropriate regulatory mechanisms. Each NPDES
					 permit assigned a Waste Load Allocation (WLA) shall be reopened or amended at
					 reissuance, in accordance with applicable laws, to incorporate the applicable
					 WLA as a permit requirement.
By July 15, 2018, the TMDL shall be re-considered to
					 incorporate new information from technical or scientific studies, or to address
					 revisions to water quality standards, such as adoption of revised water quality
					 objectives based on recommendations from U.S. EPA.
