If my business has a Regulated SIC Code and does not have one of the required documents (WDID, NONA, or NEC) to verify enrollment in the NPDES Stormwater IGP, who should I contact?

In City businesses with a Regulated SIC Code as determined by the SWRCB that are unable to verify enrollment in the NPDES Stormwater IGP by providing one of the required documents (WDID, NONA or NEC) with the City’s business license application, should review the requirements for NPDES Stormwater IGP to ensure that the permit coverage is applicable and apply for Stormwater IGP coverage with the SWRCB using the links below:
