The State Water Board has released two new drafts of general storm water NPDES permits this summer.
The new draft General Permit for the Discharge of Storm Water Associated with Industrial Activities is a substantial change from the draft released in January 2011. It has notably removed numeric effluent limitations, largely due to the difficulty of developing technology-based limits for all industrial sectors, but still includes numeric action levels. In addition, it implements new cost-saving measures for sampling and monitoring. Public comment will be accepted on the draft permit until noon on September 21, 2012, and the State Water Board will hold a public hearing on October 17, 2012 in Sacramento.
The State Water Board also issued a new draft of its Phase II General Permit for Small Municipal Separate Storm Sewer Systems (MS4s). Although the deadline for written comments has now passed, the public can still attend a public hearing on August 8, 2012 in Sacramento and provide oral comment.
