TMDL Projects - Clear Lake Nutrient TMDL

Information Regarding the Status of Load Allocations

In 2016, Central Valley Water Board issued 13267 Enforcement Orders to all responsible parties named in the Clear Lake Nutrient TMDL. A 13267 Order is a formal enforcement action that utilizes Water Code Section 13267 authority to require further information or studies from dischargers. The information from the 13267 Order responses was summarized in the Technical Memorandum released in July 2018. As of 2019, Central Valley Water Board staff are in the process of drafting and issuing 13267 Orders to responsible parties that have not demonstrated compliance with the TMDL allocation. This process is meant to address data gaps and estimate the current status of load reductions.
