Frequently asked questions

Does my facility need a storm water permit and a SWPPP?

Industrial facilities in regulated categories that discharge storm water associated with industrial activity generally need coverage under an NPDES industrial general permit — EPA's Multi-Sector General Permit (MSGP) or a state equivalent such as California's Industrial General Permit — and must prepare a Storm Water Pollution Prevention Plan (SWPPP). Construction sites disturbing one or more acres need coverage under the Construction General Permit.

What is a SWPPP?

A SWPPP is a site-specific plan documenting your site layout and drainage, potential pollutant sources, the Best Management Practices (BMPs) you'll use to control them, and your monitoring, inspection, training, and corrective-action procedures. It's the core document an inspector will ask to see.

What ongoing obligations come with permit coverage?

Typically routine and rain-event visual inspections, periodic sampling and analytical monitoring compared against benchmark values, annual reporting, employee training, and ongoing BMP maintenance — all backed by recordkeeping you can produce on demand.

What happens if monitoring results exceed benchmarks?

Benchmark exceedances trigger escalating corrective measures — for example, the tiered Exceedance Response Actions under California's Industrial General Permit. Failing to investigate and respond can lead to agency enforcement and, in some states, citizen-suit liability.

Can SafetyNet run the inspections and monitoring for us?

Yes — we develop the SWPPP and then run the recurring inspection schedule, coordinate sampling, and prepare the annual report the permit requires, so compliance stays current instead of lapsing between deadlines.
