FOG (Fat, Oil and Grease):
BY FRANK NADEAU, WASTEWATER TECHNICIAN I
Sewer Public Enemy No. 1
SMITHFIELD IS A
town of approximately 8,000 residents situated on the bank of the Pagan River, just west of where the James River meets the Chesapeake Bay. During a routine contact visit to the town of Smithfield a couple of years ago, I met a new hire town employee. His name is Will Councill, and he had just been hired as FOG Inspector. I asked him what he was going to be doing. His answer was quite vague as he really didn’t know exactly what the whole idea was. Since that meeting, Mr. Councill has grown in his job and those sewer enemies are losing the battle. In 2006, the town of Smithfield entered into a Consent Order with the DEQ. One part of that order was to reduce the amount of fat, oils and grease going into the collection system and being piped to the Hampton Roads Sanitation District treatment facility. Town manager Peter Stephenson and Sonja Eubank, public works administrator, acquired a sample ordinance which had enforcement capability from the Hampton Roads Planning District Commission, tweaked it to pass the Town’s Attorney, and it was enthusiastically adopted by the Town Council. The town initiated a series of educational meetings with the residents and with food preparation owners. The meetings prepared them to meet the requirements of the new ordinance and allow time for implementation. They also conducted one-onone visits to explain the reasons and requirements with the food preparation owners. Notifications of the new ordinance were sent out in Dec. 2009 and Jan. 2010, with three months to comply. Along with continuing education and the presence of the FOG inspector, this procedure resulted in very few complaints for the town of Smithfield. As a result of the new ordinance, grease traps had to be installed if not already present. Traps have to be regularly pumped out and a scheduled inspection plan has been implemented. Traps are allowed up to 1/3 their depth in FOG accumulation and up to ¼ depth of solids accumulation. The traps are pumped and most of the contents are purchased by Valley Proteins, an animal feed processor. Trapping FOG also reduces maintenance of the collection system. One of the most odor-causing objects in a manhole is a grease ball collecting all sorts of unsavory materials. These have to be pulled from the manhole and disposed of by the maintenance people. The town has seen a dramatic increase in the amount of FOG collected. In 2009, 156,000 pounds of FOG were collected, compared to 303,000 pounds in 2011, and in the first quarter of 2012, 90,000 pounds were collected.
One part of that order was to reduce the amount of fat, oils and grease going into the collection system and being piped to the Hampton Roads Sanitation District treatment facility.
