Key Facts
- The article says FOG is an environmental-compliance issue in commercial kitchens, not only a maintenance issue.
- Nearly every jurisdiction regulates FOG discharge to the sanitary sewer through a local sewer-use ordinance and pretreatment program.
- The grease interceptor is described as a compliance device, with service tied to kitchen volume.
- The article cites a common '25 percent rule' to pump and clean interceptors before grease and solids reach a quarter of the interceptor depth.
- Under MS4 illicit discharge provisions, non-stormwater discharges such as grease-laden runoff are presumptively prohibited.
What Happened
EP Online argues that fats, oils, and grease (FOG) should be managed as an environmental-compliance issue in commercial kitchens, not just as a plumbing nuisance. The report frames FOG as sitting at the intersection of wastewater pretreatment, stormwater permitting, waste diversion, and the clean-fuel economy.
The source says the problem is often underestimated because it can begin with a clogged line or backed-up trap, but the regulatory exposure extends well beyond routine maintenance.
Why It Matters
According to the report, neglected FOG controls can allow grease to enter the collection system, harden into deposits, and contribute to sanitary sewer overflows. Those overflows are exactly what pretreatment programs are designed to prevent, and the article says fines for contributing to them are real.
The piece also highlights stormwater as a frequently missed pathway. Used-oil containers stored outdoors, dumpster-pad washdown, and grease-laden runoff from pressure-washing a hood or pad can all reach a storm drain, creating illicit discharge risk under MS4 permit provisions.
Key Details
The article says nearly every jurisdiction regulates FOG discharge to the sanitary sewer through a local sewer-use ordinance and pretreatment program. It identifies the grease interceptor as a compliance device that must be serviced on a schedule matched to kitchen volume.
- A common benchmark is the '25 percent rule' for pumping and cleaning interceptors before grease and solids reach one-quarter of the interceptor depth.
- High-volume operations may need a tighter service schedule than the benchmark.
- Manifests and service records are described as the first documents an inspector asks for.
The report also notes that managed well, used cooking oil can support waste diversion and the clean-fuel economy, turning a liability into an asset.
What To Watch Next
Facilities should review interceptor service intervals, outdoor storage practices, and cleaning methods that can move grease into stormwater pathways. The article suggests that FOG controls need to be handled as part of broader compliance management, not as isolated maintenance tasks.
For commercial kitchens and multi-site operators, the practical focus is on documentation, routine service, and preventing any discharge route that can reach sewer or storm systems.
Alliance's Take
For buyers and operators, the immediate takeaway is that FOG management is a service-and-documentation program, not just a janitorial task. Interceptor pumping, manifests, and service records should be treated as compliance essentials.
For EHS and facilities teams, outdoor oil storage and washdown practices deserve the same review as sewer pretreatment controls, because the report says stormwater pathways can create separate permit exposure.

Frequently asked questions
Why is FOG a compliance issue in commercial kitchens?
The report says FOG can affect both sanitary sewer pretreatment and stormwater controls, so poor management can lead to violations, overflows, and fines.
What servicing benchmark does the article mention for grease interceptors?
It cites the common '25 percent rule,' meaning interceptors should be pumped and cleaned before grease and solids reach a quarter of the depth.
What records matter most during an inspection?
The article says manifests and service records are the first things an inspector asks for.
