EPA NPDES Permit Application

Overview

Draft and validate NPDES permit application documentation under the Clean Water Act §402. Covers facility characterisation, outfall and effluent data, SWPPP, and compliance schedule per EPA Form 2.

Example Conversation

You: We need an NPDES permit application for our industrial outfall. Include facility and outfall characterisation, effluent data with ELG comparison, and SWPPP with inspection schedule.

Agent: I’ll draft the application using the NPDES template and checklist, then run npdes_application_checker to verify all required elements.

Agent: Created npdes-application.md. Running npdes_application_checker…

Agent: FAIL — site_map and SWPPP inspection schedule weak. I’ve added a site map section and a monthly inspection schedule for stormwater controls. Re-running…

Agent: PASS — all NPDES application elements are present. Ready for submission or internal review.

What the Tools Validate

npdes_application_checker scans the NPDES application:

• Required elements: Facility characterisation (SIC/NAICS, location, receiving water, outfall map), outfall characterisation (flow, pollutant parameters, treatment), effluent data and ELG comparison, SWPPP with inspection schedule, site map with outfall locations.
• Rule: Each element must be clearly addressed in the document.
• Output: PASS if all elements are present; FAIL with a list of missing or weak areas. Add content and re-run until PASS.
