July 8, 2013 U.S. EPA Adopts Malibu Creek Regulations On July 2nd, the U.S. Environmental Protection Agency established new water quality standards for Malibu Creek and Lagoon, which when implemented, will have a severe effect on wastewater treatment costs for customers of the Las Virgenes – Triunfo Joint Powers Authority (JPA), comprised of Las Virgenes Municipal Water District and Triunfo Sanitation District. Intended to reduce or eliminate the presence of algae in the watershed, the document contains stringent regulations for nitrogen and phosphorous that cannot be met using the existing wastewater treatment processes.

JPA Opposes EPA Proposal for Malibu Creek; Filing Cites Faulty Scientific Foundations May 20, 2013  EPA Postpones Announcing Malibu Creek & Lagoon TMDLs In a statement released Friday May 17, the U.S. EPA said it will extend the implementation of new water quality standards (TMDLs) for Malibu Creek and Lagoon to July 2, “to allow further discussion of the proposed terms of these TMDLs with stakeholders and to address public comments on the proposed TMDLs.” The EPA’s new TMDLs had been scheduled to be established on May 23. David W. Pedersen, Administering Agent and General Manager for the Las Virgenes – Triunfo Joint Powers Authority (JPA) said, “We appreciate the EPA’s decision to take additional time in considering this important matter, which will have enduring impacts in our service area. The JPA supports actions for the watershed based on sound science that will produce benefits in proportion to their costs.” Mr. Pedersen said he believes the EPA is being responsive to the concerns of the community and allowing more time to consider all the information submitted is an appropriate approach toward building consensus for actions that will benefit the watershed.

For more information on the EPA’s announcement: http://www.epa.gov/region9/water/tmdl/progress.html May 6, 2013 Thank you for attending the May 1 EPA Workshop at Agoura Hills City Hall. Your interest and presence sent a powerful message that our community shares an interest in the region’s environmental responsibilities, but at the same time, recognize that the benefits of any proposed standards must be real and in proportion to their costs. A number of you have asked us, “What else can I do?” Here is a sample letter (PDF format or Word format) you can use to express your concerns to the EPA. Feel free to modify the letter to express your personal views. You can also send a copy of this letter to your elected state and federal representative (click here for addresses).  Sincerely, David W. Pedersen, P.E.

The Las Virgenes – Triunfo Joint Powers Authority (JPA), comprised of Las Virgenes Municipal Water District (LVMWD) and Triunfo Sanitation District (TSD) is voicing strong opposition to the U.S. Environmental Protection Agency (EPA) proposal of new water quality standards for Malibu Creek. The JPA has filed a 75-page document with the EPA citing serious flaws in methodology, concerns about potential high costs to meet standards which are unwarranted, given the natural background conditions found in the watershed, and the time frame for public review was very brief. The documents and additional information on this issue, including comment letters, is also posted at www.TriunfoSanitation.com.
