Industrial General Permit Fact Sheet

NELs for storm water discharges associated with industrial activity due to insufficient
information at the time of adoption of this General Permit.

On April 17, 1997, the State Water Board issued NPDES General Permit for Industrial
Storm Water Discharges, Excluding Construction Activities, Water Quality
Order 97-03-DWQ (previous permit). This General Permit, Order 2014-0057-DWQ
rescinds the previous permit and serves as the statewide general permit for industrial
storm water discharges. The State Water Board concludes that significant revisions to
the previous permit requirements are necessary for implementation, consistency and
objective enforcement. As discussed in this Fact Sheet, this General Permit requires
Dischargers to:

 Eliminate unauthorized non-storm water discharges (NSWDs);

 Develop and implement storm water pollution prevention plans (SWPPPs) that
include best management practices (BMPs);

 Implement minimum BMPs, and advanced BMPs as necessary, to achieve
compliance with the effluent and receiving water limitations of this General Permit;

 Conduct monitoring, including visual observations and analytical storm water
monitoring for indicator parameters;

 Compare monitoring results for monitored parameters to applicable numeric action
levels (NALs) derived from the U.S. EPA 2008 Multi-Sector General Permit for Storm
Water Discharges Associated with Industrial Activity (2008 MSGP) and other
industrial storm water discharge monitoring data collected in California;

 Perform the appropriate Exceedance Response Actions (ERAs) when there are
exceedances of the NALs; and,

 Certify and submit all permit-related compliance documents via the Storm Water
Multiple Application and Report Tracking System (SMARTS). Dischargers shall
certify and submit these documents which include, but are not limited to, Permit
Registration Documents (PRDs) including Notices of Intent (NOIs), No Exposure
Certifications (NECs), and Storm Water Pollution Prevention Plans (SWPPPs), as
well as Annual Reports, Notices of Termination (NOTs), Level 1 ERA Reports, and
Level 2 ERA Technical Reports.

C. Blue Ribbon Panel of Experts (Panel)

In 2005 and 2006, the State Water Board convened a Blue Ribbon Panel of Experts
(Panel) to address the feasibility of NELs in California’s storm water permits.
Specifically, the Panel was charged with answering the following questions:

Is it technically feasible to establish numeric effluent limitations, or
some other quantifiable limit, for inclusion in storm water permits?
