When the State Water Resources Control Board (“State Board”) adopted the Industrial General Storm Water Permit in 2014 (the “IGP”), the State Board reserved for a later day how to incorporate Total Maximum Daily Load (“TMDL”)-specific requirements for watersheds around the state into the IGP. Specifically, the State Board set July 1, 2016, as the deadline for Regional Water Quality Control Boards (“Regional Boards”) to propose TMDL-specific requirements for incorporation into the IGP.
Regional Boards around the state are now accepting public comment on proposed TMDL-specific requirements. Over the past several weeks the Los Angeles, San Diego, San Francisco, and Santa Ana Regional Boards have all issued public notices inviting 30-days of public comment on a variety of TMDLs. For example, the San Diego Regional Board is accepting comment through March 31 on TMDL-specific requirements for a wide range of pollutants including diazinon, copper, lead, zinc, bacteria, sediments, nitrogen, phosphorus, and dissolved copper in watersheds from Chollas Creek and Shelter Island, to beaches and coastal lagoons. (Please check your local Regional Board’s website for all relevant notices.)
