If a facility does not have industrial materials outdoors, does not conduct industrial activities outdoors and there is no exposure to storm water (in accordance with Section XVII of the Industrial General Permit) the facility may qualify for the NEC. The NEC allows for a reduction in monitoring storm water permit requirements, and the annual fee. This brochure summarizes the NEC requirements that can be found in the Industrial General Permit (State Water Board Order 2014-0057-DWQ).

This 2 page summary of the key components of the Industrial General Permit is intended to introduce the permit to individuals new to the program.
