Stormwater Discharge Permits
In California and the Federal EPA, 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. Adhering to this policy we assure meeting the environmental regulations.
Regulated facilities are required to:
- Submit an Initial Notification of Intent (NOI)
- Develop a Stormwater Pollution Prevention Plan
- Develop a Stormwater Monitoring Plan
- Conduct regular visual observations and collect stormwater samples
- Prepare an Annual Report of observation and sampling results
CDMS prepares the Notification of Intent (NOI), the Pollution Prevention Plan, Monitoring Program, and the Annual Stormwater Report required to comply with this permit. Contact CDMS for more information.
Stormwater Sampling Kits
CDMS provides 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 provides analysis reports for use in the Annual Stormwater Report.
Stormwater Annual Reports
CDMS prepares Annual Stormwater Reports for facilities to meet annual Reporting requirements. Reports are due July 1 every year.
Form information on how this regulation effects your facility, assistance in developing required programs or preparing reports, or to order Sampling kits, contact CDMS.
Stormwater Sampling Reduction
California Storm Water regulations provide companies with an opportunity to reduce monitoring activities for their Storm Water Program. The saving money and time in the form of reduced lab fees and sampling efforts.
In the Storm Water Program for at least the past three years
Taken 2 samples a year at each discharge point
Sampling results are below the established benchmark value.
Met Annual Report requirements during the past three years
Sampling reduced to two samples over the next four years
Stormwater regulations now allow qualified companies to be exempt from most of the sampling requirements. Chemical Data Management Systems is an environmental compliance service company and we have been preparing storm water and compliance plans for the past 10 years. We can help you to obtain this storm water sampling exemption. Contact CDMS for assistance. We will conduct the analysis of your data and prepare the necessary documentation to process the exemption.
March 2013 – Modified Stormwater Permit Regulation News
A modified draft permit has been proposed, but not yet adopted. The current draft does provide for some significant change to the regulation and requirements. The original draft was modified based on initial public comments and the second draft comment period has closed. CDMS is monitoring the status of this regulation and will send out a newsletter Hazardous Material Alert should regulations be finalized.
