Monthly inspections are required for all industrial facilities enrolled under the IGP. Their main goal is to catch potential stormwater pollution issues before they become problems. Typically, inspections must occur during dry weather conditions and focus on stormwater best management practices (BMPs), housekeeping, and signs of illicit discharges.
3 Key Areas to Focus On
When conducting your inspection, focus on three critical areas:
- Unauthorized Non-Storm Water Discharges (NSWDs):
These are discharges that are not permitted under your Notice of Intent (NOI). Common examples include process water leaks or pressure washing runoff. - Authorized NSWDs:
These include things like fire hydrant flushing or air conditioning condensate — but they still must be properly managed and documented. - Potential Future Issues:
Are there containers near drains? Are BMPs damaged or out of place? Anything that could lead to a violation should be flagged and corrected.
Avoiding Unauthorized NSWDs
According to recent IGP compliance updates, unauthorized discharges are one of the top causes of enforcement actions. Don’t wait for a rain event to expose problems. If you see stains, puddles, or leaks near storm drains, that’s your cue to act.
Why Documentation Matters
Always document what was inspected, who conducted the inspection, and any corrective actions taken. These reports aren’t just for your records — they’re critical during audits or if the Water Board requests a compliance review.
Need Help from a QISP?
Facilities that fall into Exceedance Response Action (ERA) Levels 1 or 2 must have a Qualified Industrial Storm Water Practitioner (QISP) involved in inspections and reporting. Even if you’re still in baseline status, working with a QISP ensures your site stays prepared and in compliance.

FAQs:
Q: What is the IGP monthly inspection requirement?
A: Facilities must perform monthly visual inspections of stormwater areas to identify potential sources of pollution and verify BMP effectiveness.
Q: What happens if you miss a monthly inspection?
A: Missing inspections can lead to permit violations, increased monitoring requirements, or enforcement actions.
Q: Who can conduct these inspections?
A: Staff trained in IGP compliance can conduct them. However, sites under ERA Level 1 or 2 must involve a QISP.
