On July 7, the State Water Board released the revised toxicity provisions and updated staff report. The proposed toxicity provisions will establish numeric water quality objectives for both acute and chronic toxicity, and a program of implementation for dischargers to surface waters. CASA has been actively engaged in the development of the toxicity provisions, a process that has taken many years. State Water Board staff will host a workshop on July 29 to review the revisions, and formal comments are due August 24. Later this month, the State Water Board staff will release a response to comments, which they indicated will only address the draft provisions released over the last couple of years and exclude matters related to the test of significant toxicity (TST). CASA will be submitting written comments on the revised toxicity provisions. If you have questions or comments, please reach out to Adam Link. A summary of the changes is available here, and the materials for the next draft of the regulations are here.
