The State Water Resources Control Board (SWRCB) approved a new Industrial General Storm Water Permit (IGP) on April 1st of this year. The new permit requirements go into effect July 1, 2015.

The IGP regulates discharges associated within 10 broad categories of industrial activities. This permit requires the implementation of management measures that will achieve performance standards stricter than those previously needed.

It also requires the development of a Storm Water Pollution Prevention Plan (SWPPP) and a monitoring plan. The SWPPP is required to identify sources of pollutants, the means to control pollutant sources and reduce storm water pollution.

There are significant differences between the requirements of the previous storm water permit and the new permit and noncompliance quickly adds up to large penalties and fines. Additionally, the new IGP covers many manufacturing facilities that were not included under the previous permit.

Here is a link to a list of the more significant changes.

There are noteworthy benefits for companies to start evaluating their compliance situation in advance. In order to assist CMTA members comply with the new IGP, CMTA will host at least one “not-for-profit” storm water compliance seminar on January 21 in Sacramento and likely one in Southern California, depending on demand. We expect the seminar to last approximately 3-4 hours.  Associate CMTA members AECOM/Rust (an environmental consulting firm) and Downey Brand (a law firm) have volunteered to assist as well as a representative of the SWRCB.

If you or your firm is interested in attending, please contact Mike Rogge at
