TMDL for Metals in Ballona Creek (Metals TMDL)

TMDL Effective Date: January 11, 2006
Final Compliance Date: January 11, 2021

The City of Los Angeles is mandated by the Regional Water Quality Control Board (RWQCB) to address the water quality impairments in Reach 1, Reach 2, and Sepulveda Channel associated with metals (copper, lead, selenium, and zinc in both total dissolved and total recoverable form in the water column). Metals impairments in sediments are addressed in the TMDL for Contaminated Sediments in Ballona Creek Estuary.

The RWQCB adopted the Ballona Creek Metals TMDL on July 7, 2005 and the TMDL became effective on January 11, 2006. The Metals TMDL requires that the responsible jurisdictions submit the draft Coordinated Monitoring Plan (CMP) to the RWQCB by January 11, 2007 and the TMDL Implementation Plan by January 11, 2010.

The Metals TMDL defines milestones for achieving compliance with dry- and wet-weather waste load allocations (WLAs) based on the percent of total watershed area (excluding Ballona Estuary, which is covered under Estuary Toxics TMDL):

2012: demonstrate compliance for 50% dry-weather and 25% wet-weather total drainage area WLAs
2014: demonstrate compliance for 75% dry-weather total drainage area WLAs
2016: demonstrate compliance for 100% dry-weather and 50% wet-weather drainage area WLAs
2021: demonstrate compliance for 100% both wet- and dry-weather total drainage area WLAs
The RWQCB identified City of Culver City, City of Inglewood, City of West Hollywood, City of Beverly Hills, Caltrans, City of Los Angeles, and County of Los Angeles as the agencies responsible for compliance with the Metals TMDL. As City of Los Angeles is the largest city in the watershed, the Watershed Protection Division (WPD) of Bureau of Sanitation is the lead office in charge of developing CMPs and Implementation Plans for this TMDL. County of Los Angeles is developing a separate Implementation Plan.
Over the past two years, WPD, together with other responsible agencies has conducted community stakeholder workshops and one hundred or more one-to-one meetings and field visits to consult with the stakeholders on Implementation Plan opportunities. Two stakeholder workshops were held on the following dates:
Workshop 1: Watershed Characterization, City of Culver City Council Chambers, November 6, 2008
Workshop 2: Best Management Practices Strategies, City of Los Angeles Hyperion Treatment Facility, March 3, 2009.

Both workshops were attended by about two hundred stakeholders that included non-governmental organizations, neighborhood councils, private residents, universities, and state and local governments.

As a result, the Ballona Creek Metal Implementation Plan builds upon the expertise and knowledge of stakeholders and existing plans. The plan focuses on sustainability, infiltration, use of and expansion of open space, multi-benefit, and watershed-wide approach.
