PROPOSED AMENDMENTS TO ORDER NO. R9-2013-0001, AS AMENDED BY ORDER NO. R9-2015-0001

On February 11, 2015, the San Diego Water Board adopted Order No. R9-2015-0001, which amended Order No. R9-2013-0001, to extend coverage of the Regional MS4 Permit to the Orange County Copermittees and address a variety of other issues. During the proceedings for Order No. R9-2015-0001, the San Diego Water Board deferred consideration of two concepts proposed as permit amendments to establish 1) a definition of the term "prior lawful approval" for priority development projects, and 2) an alternative compliance pathway that would conditionally allow the Copermittees to be deemed in compliance with the receiving water limitations and related prohibitions of the Regional MS4 Permit. The San Diego Water Board scheduled a series of workshops to receive comments and information from the Copermittees and other key stakeholder groups concerning the prior lawful approval and alternative compliance pathway issues.
