Ensure you’re EPA-compliant and inspection-ready with this field-tested industrial stormwater inspection checklist used by us.
General Site Information
Make sure you’ve recorded and updated the following:
- Project Name & Location
- NPDES Tracking Number (if applicable)
- Current Phase of Construction (e.g., grading, framing, etc.)
- Inspector Name and Contact Info
- Inspection Type
- Regular
- Pre-Storm Event
- During-Storm Event
- Post-Storm Event
Weather & Storm Events
- Has there been a storm since the last inspection?
- If yes:
- Record storm start date/time
- Duration (hours)
- Estimated rainfall (inches)
- If yes:
- What’s the weather at the time of inspection?
- (e.g., clear, rainy, cloudy, windy, snowy)
- Any stormwater discharges since last visit?
- Are there discharges currently happening?
Site-Specific Best Management Practices (BMPs)
Review and document all BMPs, both structural (e.g., silt fences, check dams) and non-structural (e.g., trash areas, material storage).
For each BMP:
- Is it installed properly?
- Does it need maintenance?
- Any corrective action needed? Note who is responsible and the due date.
(We recommend numbering BMPs on your site map for easier tracking.)
