FOG - Fats, Oils & Grease


Fats, Oils, and Grease (FOG) from food establishment or residential activity has the potential to cause many problems in sanitary sewer lines. A grease trap or interceptor can be used to reduce the amount of FOG entering the sewer system. FOG that is not contained by a grease trap or interceptor has the risk of collecting on the sides of the pipes causing sewer blockages. These blockages can result in sanitary sewer overflows (SSOs) which then can be released into our rivers and streams. The costs of increased maintenance to the sewer lines to prevent blockages are high. In an effort to reduce operating costs and to help protect human health and the environment, the Henry County PSA has begun to implement a FOG Control Program. This program will also help us meet the most current EPA and Virginia DEQ requirements for sewer discharges. Under the Henry County PSA Pretreatment Regulations, Section 7.1, discharges of FOG into the sewer system shall not exceed 150 mg/L.
