## 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.
