What does SWPPP stand for?

SWPPP stands for Storm Water Pollution Prevention Plan.


What is the purpose of a SWPPP?

A Storm Water Pollution Prevention Plan (SWPPP) is a site-specific document that identifies industrial operations and pollution control practices that are being implemented, to prevent and minimize pollutants from reaching storm water runoff. The SWPPP is required by Storm Water Permits pursuant to local permitting authority’s adopted NPDES program. Among other things, the SWPPP requires BMPS (Best Management Practices) to prevent or minimize storm water pollution.


Do I need a SWPPP?

If your business is defined as Industrial, and your facility operations contribute to storm water runoff, you are required to apply for California’s Industrial General Permit. A SWPPP is required for an Industrial General Permit holder to discharge storm water. Dischargers that qualify for a Non Exposure Certification (NEC) are exempt from the SWPPP requirements.

When do I need to complete the SWPPP?

The SWPPP should be prepared before submitting a Notice of Intent (NOI) or General Permit application. The SWPPP should be implemented by the start of industrial operations.

How do I submit or revise the SWPPP?

In California, the SWPPP is required to be submitted electronically through SMARTS (Stormwater Multiple Application and Report Tracking System). SWPPPs should be revised whenever it is necessary. The SWPPP is considered a living document and must be

updated to reflect any changes in industrial operations and pollution prevention practices. The SWPPP also requires an Annual Comprehensive Facility Compliance Evaluation.

Who submits the SWPPP?

Within the SMARTS program, Dischargers are required to certify and submit Permit Registration Documents. The Discharger must assign a

LRP (Legally Responsible Person), who is required to submit documents related to permit coverage via SMARTS. SWPPPs are submitted and certified by the LRP for NOI coverage.

What does Frog do?

Frog starts by performing a site walk where we evaluate your industrial facility, assess your potential pollutants sources, and recommend Best Management Practices (BMPs) to reduce pollutants in your stormwater run-off. Then, we develop your SWPPP, which

includes storm water outfalls and sampling points, as well as a facility diagram, a potential pollutant diagram and a monitoring diagram. Our writers can also update your existing SWPPP to bring your facility into compliance, if needed. SWPPP development can be part of Frog’s annual monitoring contract, or it can be a stand-alone service.
