Industrial & high-risk programs; locality to adopt, etc., runoff programs.

Authorizes any locality that owns or operates a permitted municipal separate storm sewer system (MS4) to adopt and administer an industrial and high-risk runoff program. The bill authorizes any such locality to include in its industrial and high-risk program an industrial or commercial facility notwithstanding the fact that the facility is also subject to certain permits or the federal Emergency Planning and Community Right-to-Know Act. The bill limits the ability of the State Water Control Board (the Board), unless it is required to do so by federal law, to impose certain regulatory conditions on any locality that administers such a program and prohibits the Board from modifying existing MS4 permits to avoid such limitation. The bill authorizes the Board to require a locality to report an industrial or commercial facility if it becomes aware of a violation of an industrial stormwater management requirement.
