NPDES Inspections

Ensuring Environmental Compliance with NPDES Inspections

RSP Engineers provides certified NPDES Inspections to keep your construction site in full compliance with the Clean Water Act. Our qualified inspectors monitor your site's erosion and sediment control measures, conduct routine inspections, and manage all necessary documentation and reporting. We help you avoid costly fines and project delays by ensuring your project meets all stormwater pollution prevention requirements.

Proactive Management of Stormwater Compliance

The National Pollutant Discharge Elimination System (NPDES) permit program regulates stormwater discharges from construction sites. Failure to comply can result in significant penalties. Our service provides peace of mind by managing all aspects of your site's stormwater compliance.

When to bring in NPDES inspection

  • A construction project disturbs one acre or more, or is part of a larger common plan of development, and needs an NPDES permit and a site-specific SWPPP.
  • The permit requires routine documented inspections of erosion and sediment controls, including after qualifying rain events, with documented reports.
  • A regulatory audit is expected and the project wants a representative who can speak to its compliance record.
  • A site has been stabilized and the permit needs to be closed out with a Notice of Termination.
