The California State Water Resources Control Board is hosting a series of public workshops throughout the state, between now and April, on the new Industrial General Permit (IGP) requirements. The new National Pollution Discharge Elimination System (NPDES) Permit for storm water associated with industrial activity is effective July 1, 2015. 

The IGP is a statewide, general NPDES permit that regulates the discharge of storm water associated with industrial activity as defined by the U.S. Environmental Protection Agency (EPA). Storm water and urban runoff are significant sources of water pollution and can threaten aquatic life and public health.

The management of storm water at industrial sites in California is currently regulated under a permit that was issued in 1997. This permit was originally scheduled for reissue in 2002 but was delayed for more than ten years until 2013 when a revised draft permit was released for public comment and subsequent meetings with stakeholders. As a result, a revised IGP was adopted last year with an effective date of July 1, 2015. A number of significant changes are forthcoming for permittees, a list of which can be found here.

SPI had earlier submitted comments to the Board speaking to the material handling requirements for facilities using resin pellets. We reiterated the industry’s support for the employment of best management practices (BMPs) as prescribed by Operation Clean Sweep in preventing the unwarranted release of pellets into the environment.  Members are again strongly encouraged to review any BMPs they have in place related to resin pellets and make any necessary adjustments.
