When a restaurant owner calls with a FOG question, the first challenge is figuring out which of the half-dozen agencies actually has authority. Federal, state, city, and county all have roles. So do third-party contractors hired by utilities. Here's how it actually works in practice.
Local Wastewater Utility: The Primary Enforcer
Your local wastewater utility — also called the POTW (publicly owned treatment works), sewer authority, or water reclamation district — handles roughly 95 percent of day-to-day FOG enforcement. They have these powers:
- Issue FOG discharge permits and set permit fees.
- Inspect grease traps on scheduled and surprise visits.
- Issue Notices of Violation (NOVs) and assess fines.
- Require emergency pump-outs.
- Suspend or revoke FOG permits, which effectively closes your kitchen.
- License and regulate grease haulers.
In large cities, this function lives in a dedicated FOG program office with several inspectors. In mid-size cities, it's typically one pretreatment coordinator. In small towns, it may be a part-time duty of the utility manager.
State Environmental Agency: Secondary Authority
Each state has an environmental agency — TCEQ in Texas, CalEPA in California, NYSDEC in New York, and equivalents elsewhere. State agencies step in when:
- A FOG discharge causes a sanitary sewer overflow that reaches waterways.
- Industrial FOG generators need direct permits (rare for restaurants).
- A POTW fails to adequately run its pretreatment program.
- Multi-jurisdictional issues arise (a shared sewer system across cities).
You rarely interact with state agencies directly unless something has gone badly wrong. When you do, the penalties are larger.
US EPA: Federal Backstop
The US EPA enforces the Clean Water Act and pretreatment regulations under 40 CFR Part 403. The EPA rarely pursues individual restaurants directly. Its role is:
- Require POTWs to run compliant pretreatment programs.
- Enter consent decrees with POTWs that allow sewer overflows.
- Issue federal Clean Water Act penalties (up to $25,000+ per day per violation, inflation-adjusted).
- Prosecute criminal violations in egregious cases — typically illegal FOG dumping into storm drains or waterways.
Most restaurants never interact with the EPA. But an EPA consent decree against your local POTW usually means tighter enforcement at the restaurant level, since the POTW must show the EPA it's cracking down on dischargers.
Health Department: Parallel Jurisdiction
Your local health department inspects restaurants for food safety, but they also check grease traps. Health inspectors can cite FOG issues through their own authority — often treating a backed-up grease trap as a sanitation hazard. Health department actions can escalate to temporary closure faster than wastewater authority actions, because the public health framing moves through different administrative channels.
Third-Party Inspectors and Contractors
Some cities contract with private firms to perform FOG inspections. These contractors carry the same legal authority as city staff but often have tighter inspection routines and more consistent enforcement. Treat them as you would any city inspector: cooperative, documented, and don't argue in the moment.
Who to Call for What
| Question or Issue | Who to Contact |
|---|---|
| Any question about pumping, permits, or fines | Local wastewater utility FOG program |
| Emergency backup or overflow | Licensed hauler immediately, then wastewater utility within 24 hours |
| Hauler license verification | Local wastewater utility's approved hauler list |
| Questions about state plumbing code | State plumbing board or licensed local plumber |
| Suspected illegal dumping by a hauler | State environmental agency |
| Violation notice you believe is incorrect | Wastewater utility's appeal or hearing officer |
Practical Advice
Build a relationship with your local FOG program before you need one. Introduce yourself, ask clarifying questions in writing, and request their preferred ways of communicating (email usually beats phone). When a violation does come, you'll have a known contact who can explain options and speed up resolution.
