FOG Requirements explained by Cater Waste – Waste Water Trade Effluent Licenses

Some Regional variations exist between the legal requirements within relevant Local Environmental Authorities (LEA`s). Trade Effluent Discharge licenses are the most common legal requirement which supercede but may include voluntary codes of standards or parts thereof. Most local council areas require restaurants to put in place measures to reduce the amount of FOG (Fats, Oils and Grease) that discharge into their drains.


CaterWaste manufacture and supply a range of Grease Control Methods to help you meet your FOG consent level of discharge. To help you understand what these Regulations mean for you, read the Caterwaste FOG guide below.


What are Fats, Oil and Greases (FOG)?

Fats, Oils and Greases (FOG) are produced in significant quantities from the kitchens of Food Service Establishments (F.S.E.) and is the by product of food preparation and washing up activities. Typically these FOG are washed down the drain of the sink and into the public drainage system. This can result in a breach of the Water Framework Directive.


What is the problem with Fats, Oil and Greases (FOG) entering the drain pipes?


When simply let enter the drainage system these FOG`s cool down and turn into solid form causing blockages. FOG congeals and accumulates in pipes, pumping stations and equipment. It also causes major problems at Wastewater Treatment Works and adds expense to the treatment of the water.


What are the Trade Effluent Licensing Requirements?


Most local licensing authorities throughout Ireland monitor the discharge of FOG quantities in waste water entering the drainage network. FSE operators shall be licensed to discharge FOG by means of a trade effluent license issued under the Water Pollution Act. As part of the conditions of that license, limits will be set on the amount of FOG that may be discharged to the public drainage network. Initially, premises will be inspected, advice given to the operator on the steps they must take to obtain a license and once licensed, each FSE will subsequently be visited throughout the year to ensure compliance with the limits set in their discharge license.


Who will be licensed for these Fats, Oil and Greases (FOG)

Food Service Establishments who operate wash-up facilities during the course of a trade such as hotels, pubs, restaurants, take-aways, canteens, convenience stores, cafes etc. and it is the operator of the FSE who is responsible for submitting the Trade Effluent license application.


What is the cost of a Trade Effluent (FOG) License?

As set out in the Local Govt. (Water Pollution) Regulations, there is typically a one-off application fee payable to the licensing authority. Then, similar to any other trade effluent license, there will then be an annual renewal license fee due. The annual fee will vary depending on the type of the FSE. Most licensing authorities have a team of advisers and inspectors so it is worth contacting them directly.


What happens to the removed FOG?

Waste FOG is collected by a licensed waste carrier and transported to a licensed waste management site where it is either composted, anaerobically digested or rendered to create tallow.
