Storm Water Pollution Prevention Plan (SWPPP)
A Storm Water Pollution Prevention Plan (SWPPP) is a crucial requirement for certain California-based companies to manage and mitigate stormwater pollution. It helps prevent hazardous materials and pollutants from being washed into storm drains and eventually flowing untreated into waterways. Even companies not intentionally discharging industrial wastewater into storm drains must comply with regulations that focus on unintentional discharges, such as spills or residue runoff. CDMS services offer comprehensive assistance, including preparing initial notifications, developing SWPPPs, monitoring stormwater, and submitting annual reports. Our certified practitioners can evaluate pollutant sources, implement best management practices, conduct employee training, and even provide stormwater sampling kits to facilitate and ensure regulatory compliance.
Regulatory bodies
Who needs it
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

What our service provides:
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.

What is a Storm Water Pollution Prevention Plan (SWPPP)?
SWPPP is a plan designed to prevent the contamination of stormwater runoff with pollutants from industrial or construction sites.
Why is SWPPP important in California?
California has strict regulations due to its vulnerable waterways and ecosystems that can be affected by stormwater runoff pollution.
Who needs to have a SWPPP in California?
Industrial facilities, construction sites, and municipalities that discharge stormwater into water bodies usually require a SWPPP.
What does a SWPPP include?
A SWPPP outlines pollution prevention measures, monitoring, and best management practices to control stormwater runoff.
Are there specific industries that need a SWPPP more?
Industries involving manufacturing, construction, transportation, and agriculture often require comprehensive SWPPPs.
Do I need a permit for SWPPP in California?
Yes, the California State Water Resources Control Board mandates permits for stormwater discharges under the General Industrial Stormwater Permit.
Can SWPPPs be tailored for different industries?
Yes, SWPPPs should be customized to address the specific pollutants and risks associated with each industry.
Are there fines for non-compliance with SWPPP regulations?
Yes, violations can result in substantial fines and enforcement actions from regulatory agencies.
Is SWPPP training required for employees?
Yes, employees should receive training on SWPPP requirements and best practices.
How often should a SWPPP be updated?
SWPPPs should be reviewed and updated regularly, especially if there are changes in operations or regulations.
Can SWPPs be submitted electronically?
Yes, they are required to be submitted electronically.
What is the role of a Qualified SWPPP Developer (QSD)?
A QSD is responsible for developing and implementing SWPPPs to ensure compliance with regulations.
What is the role of a Qualified SWPPPP Practitioner (QSP)?
A QSP oversees the implementation of SWPPPs and monitors stormwater discharges.
How can I prevent erosion and sediment runoff on construction sites?
Implement erosion control measures like silt fences, sediment basins, and stabilized construction entrances.
Is SWPPP required for small construction projects?
Yes, even small construction projects may require a SWPPP if they disturb a certain amount of soil.
Can SWPPPs help in LEED certification?
Yes, SWPPP practices can contribute to points in Leadership in Energy and Environmental Design (LEED) certification.
Are there any incentives for implementing effective SWPPPs?
Some regions offer incentives or recognition for companies that exceed SWPPP requirements.
Is monitoring required for SWPPPs?
Yes, regular monitoring of stormwater discharges and pollutants is a crucial aspect of SWPPP compliance.
Where can I find more information about SWPPP regulations in California?
The California State Water Resources Control Board and local water quality control boards are primary sources for detailed information on SWPPP regulations. However, if you have other questions regarding Storm Water Pollution Prevention Plan (SWPPP), you can contact us. Our skilled team of EH&S specialists is ready to assist you.
