EPA Regulations for Grease Discharge

All companies need to follow the EPA’s regulations for grease discharge in the United States when it comes to permitting the authorized production of water discharging

When it comes to industrial discharge, the government targets three types; indirect discharges, direct discharges and land application. Industrial discharge is governed at the federal, state and local levels under the Clean Water Act (CWA). The pollutants governed by these agencies include biochemical oxygen demand, toxic pollutants, fecal coliform, total suspended solids, pH and oil and grease. Oil and grease are the topics of discussion in today’s post.

Definition of Oil and Grease

What is the definition of oil and grease? These two items are constituents that are present in produced water. Because of this, oil and grease can be regulated in almost all produced water discharges. The two do not occur as a single chemical compound. Instead, they are referred to as indicator pollutants that can be found in various organic materials that respond to procedural analysis.

Grease Discharge

When it comes to owning a business, especially one that has an industrial kitchen, knowing what to do with the grease is very important. It could also mean the difference between being fined by the EPA and complying with the federal regulations. Inspections happen announced and unannounced, which is why your company needs to be in compliance with the EPA’s regulation on grease discharge around the year.

Fats, Oils and Grease (FOG)

Fats, Oils and Grease, otherwise known as FOG, are the regulation of these items when discharged from food service, food preparation and the cleanup of kitchens. Foods in which grease can be found when discarded include meat fats, lard, salad dressing, cooking oil, mayonnaise and even dairy products such as ice cream, milk and cheese.

Importance of a Grease Trap

Because of the EPA regulations on grease discharge, it is important for businesses with industrial kitchens to have a grease trap, or multiple traps, installed on their property. The grease trap is made of either metal or concrete that collects FOG or wastewater from the pipes of the kitchen. Those items are held in the trap until it is properly emptied. A certified liquid waste hauler must empty grease traps. A good thing about grease trap tanks is that most of the FOG will separate itself from the wastewater and flow to the top of the tank because some of the wastewater will continue to flow through the pipes of the business. This means that the amount of grease that flows through the pipes will be reduced because of the grease trap.

Installation of Grease Traps

It is vital to your business that a professional installs the grease traps properly. If the traps are not installed properly, they might not work well or could even let grease, or FOG, flow through the pipes. The trap should also be inspected prior to use and maintained often to make sure that there are no issues with it or cracks in it that allow grease to flow through into the pipes.
