FATS, OILS, AND GREASE
Organic polar compounds derived from animal and/or plant
sources that contain multiple carbon chain tricycleride molecules.
These substances are detectable and measurable using analytical test
procedures established in the United States Code of Federal Regulations
40 CFR 136, as may be amended from time to time. All are sometimes
referred to herein as "grease."
FOOD SERVICE ESTABLISHMENTS
Those establishments primarily engaged in activities of preparing,

GRAB SAMPLE
A sample that is taken from a waste stream without regard
to the flow in the waste stream and over a period of time not to exceed
15 minutes.
GREASE INTERCEPTOR
A structure or passive device designed for the purpose of
removing and preventing fats, oils, and grease from entering the sanitary
sewer collection system. These devices are often below-ground units
located outside the building and are built as two- or three-chamber
baffled tanks having a rated flow exceeding 50 gpm (189 L/m).
GREASE-LADEN WASTEWATER
Effluent discharge that is produced from food processing,
food preparation or other sources where grease, fats, and oils enter
automatic dishwasher pre-rinse stations, sinks, or other appurtenances.
GREASE TRAP
A passive interceptor having a rated flow 50 gpm (189L/m)
or less for separating and retaining waterborne grease and grease
complexes prior to the wastewater exiting the trap and entering the
sanitary sewer collection and treatment system. Such traps are typically
compact under-the-sink units that are near food preparation areas
and are located inside the building.
MINIMUM DESIGN CAPABILITY

technology to exceed 325 mg/L, as defined by EPA Test Method 1664,
or 275 mg/L, as identified by EPA Test Method 413.
