What does SWPPP stand for?
SWPPP stands for Stormwater Pollution Prevention Plan.
What is SWPPP?
The SWPPP is a site-specific written document that should identify industrial operations, and should identify pollution control practices that the site is implementing to prevent and minimize pollutants from reaching stormwater runoff. The SWPPP (sometimes referred to as SWP3 or SWP2 or SWPP) is required by Stormwater Permits pursuant to local permitting authority’s adopted NPDES program (authorized by Clean Water Act). Thus, the SWPPP is required under California’s Industrial General pursuant to California’s NPDES program. Among other things, the SWPPP requires BMPS (Best Management Practices) to prevent or minimize stormwater pollution.
Do I Need a SWPPP?
If your business is defined as Industrial and your facility operations contribute to stormwater runoff, you may be required to apply for California’s Industrial General Permit pursuant to the EPA’s NPDES (authorized by the CWA of 1972). Among other things, a SWPPP is required for an Industrial General Permit holder to discharge stormwater.
If I am certifying for NEC Permit Coverage, do I need a SWPPP?
No. Dischargers that qualify for an NEC are exempt from the SWPPP requirements, sampling requirements, sampling requirements, and visual observation requirements. If your facility operations have no exposure to stormwater, you should certify for NEC General Permit Coverage.
When should I prepare the SWPPP?
The SWPPP should be prepared by the Discharger before submitting a Notice of Intent (NOI) or General Permit application.
When should I implement the SWPPP?
The SWPPP should be implemented by the start of industrial operations.
How often do I need to revise the SWPPP?
SWPPPs for each site should be revised whenever it is necessary. The SWPPP is considered a living document and should be updated as necessary to reflect any changes in industrial operations and its pollution prevention practices. The SWPPP requires an Annual Comprehensive Facility Compliance Evaluation. SWPPP Implementations and Revisions must be submitted electronically via the SMARTS database.
How should I submit the SWPPP?
Some jurisdictions may require the discharger(s) to file electronically. In California, the SWPPP is required to be submitted electronically through SMARTS (Stormwater Multiple Application and Report Tracking System).
Who should submit the SWPPP?
Within the SMARTS program, Dischargers are required to certify and submit Permit Registration Documents (PRDs). PRDs include NOIs, NECs, SWPPPs, Annual Reports, NOTs, Level 1/2 ERA Reports. The Discharger must assign a LRP (Legally Responsible Person). The LRP is required to submit PRDs related to NOI permit coverage and NEC permit coverage via SMARTS. All other documents are to be submitted by the LRP or designated Duly Authorized Representative (DAR).
For NOI General Permit coverage, SWPPPs should be submitted by the LRP, since the SWPPP is one of the PRDs for NOI coverage. For NEC General Permit coverage, a SWPPP is not required.
What are the Requirements for an SWPPP?
The requirements for SWPPP vary by jurisdiction. In California, the Discharger must provide the following things:
- Facility Name and Contact Information
- Site Map
- List of Industrial Materials
- Description of Potential Pollution Sources;
- Assessment of Potential Pollutant Sources
- Minimum BMPs
- Advanced BMPs, if applicable
- Monitoring Implementation Plan
- Annual Comprehensive Site Evaluation, also called Annual Comprehensive Facility Compliance Evaluation (Annual Evaluation); and
- Date that SWPPP was initially prepared and date of each SWPPP amendment
- Signed Certification
