Storm Water Pollution Prevention Plan (SWPPP)

• California Regional Water Quality Control Board (9 regional boards operating under the State Water Resources Control Board).

In California, specific industries and facilities with hazardous materials potentially exposed to stormwater are required to obtain a Stormwater Discharge Permit.

The intent of the regulation is to reduce the impact of accidental discharges and hazardous material residuals being washed into the storm drain by stormwater run off, where it goes directly to waterways untreated. Many companies mistakenly assume that if they are not discharging any industrial wastewater into the storm drain, this regulation does not apply to them. This is not the case. Unauthorized industrial wastewater discharge to storm drains is prohibited in all cases. This regulation focuses on unintentional discharge that most companies have the potential for, including spills (i.e. during loading and unloading), residue from emissions settling on the roof and local area, outside operations or storage that may contribute to stormwater washing residues into the storm drains.

Regulated facilities are required to:

• Submit an Initial Notification of Intent (NOI)
• Develop a Stormwater Pollution Prevention Plan (SWPPP)
• Develop a Stormwater Monitoring Plan
• Conduct regular visual observations and collect stormwater samples
• Prepare an Annual Report of observation and sampling results

• EPA National Pollutant Discharge Elimination System (NPDES) stormwater regulations (40 CFR 122)
• EPA’s Multi-Sector General Permit (MSGP) for industrial stormwater discharges
• California’s Industrial General Permit (IGP), Order 2014-0057-DWQ
• Municipal separate storm sewer system (MS4) permits for local cities and counties
• California Water Code Section 13260 requiring SWPPPs
• California Stormwater Quality Association Best Management Practice Handbooks
• Regional Water Quality Control Board Basin Plans

CDMS has certified Qualified Industrial Storm Water Practitioner (QISPs) ready to assist you with:

• Preparing the Notification of Intent (NOI), developing the Storm Water Pollution Prevention Plan (SWPPP), the Stormwater Monitoring Plan and the Annual Stormwater Report for facilities to meet annual Reporting requirements. Reports are due July 1 every year.
• Conducting a Level 1 or 2 ERA evaluation of the industrial pollutant sources that are or may be related to the NAL exceedances.
• Adding BMPs and revising the facility’s Storm Water Pollution Prevention Plan (SWPPP) to prevent future NAL exceedances.
• Completing a Level 1 ERA report that includes the summary of the evaluation and a detailed description of the changes to the facility’s SWPPP.
• Assisting with the proper demonstration and completing a Level 2 ERA Action Plan and Technical Report.
• Training employees in the newly implemented SWPPP.
• Preparing Water Quality Based Corrective Action Reports (WQBCARs).

We can also supply Stormwater Sampling Kits, to make stormwater sampling easier. Kits are provided to clients before the rainy season starts, including the appropriate type and number of sampling media. The kits are then simply shipped from the site to the laboratory for analysis of the samples. CDMS also provides analysis reports for use in the Annual Stormwater Report and assistance in obtaining a reduction in the Stormwater Sampling requirements.
