Fats, Oils and Grease ( FOG ) Program

Did you know that nearly 50 percent of all sewage overflows nationwide are caused by homeowners who improperly dispose of everyday Fats, Oils and Grease ( FOG ) ? These overflows are not just public health issues, but can result in serious damage to our environment, especially pollution of our streams, rivers and the Chesapeake Bay.

As the lead agency that responds to sewage overflows, the Bureau of Utilities has taken on the challenge of educating residents on how they can and should dispose of these fats, oils and grease which are found in foods and food ingredients we use in our homes everyday: meat, cooking oil, butter, shortening, margarine, baked goods, sauces and dairy products.

What happens when you fry bacon, broil hamburgers or bake meat? When you’re finished, what remains in your cooking pan ? The answer is FOG – a real enemy of our sewer system – a substance that, when poured down your drain or into your garbage disposal, will build up over time, constrict the flow of wastewater and eventually cause sewers to back up into homes, overflow sewage into streams, rivers and the Bay.

Howard County’s Bureau of Utilities quickly responds to and resolves these backups and overflows.

However, prevention is the best and wisest solution to this growing problem.

First and foremost, we must reduce the amount of FOG that enters Howard County’s sanitary sewage system.To do this, we are asking homeowners to follow these simple steps when they are recycling or disposing of fats, oils and grease:

  • First, minimize the use of excess cooking oils and grease when cooking or frying.
  • The best way to handle used cooking grease is to pour it from the pan while it is still somewhat warm into a container that you can freeze, preferably one you'd have to throw away because it's not accepted by your local recycling program. ( Frozen juice cartons work well because they won't melt when they come in contact with hot grease ) Use a rubber spatula to scrape as much of the grease out of the pan as possible, and then it should only take one disposable paper towel to wipe the pan clean.
  • Store the container in the freezer, which will keep the grease solid, and pull it out whenever you have fats, oils and grease to dispose of. When it gets full, dump the whole container in the trash.
  • Whenever possible, find creative ways to reuse or recycle properly stored FOG. One suggestion is to turn refrigerated FOG ( now lard ) into wild bird suet by mixing it with bird seed.

Regulation of Oil, Grease and Food Related Waste Discharges to the Public Sewerage System

Regulation of Oil, Grease and Food Related Waste Discharges to the Public Sewerage System

Dear Food Service Facility Owners and Managers:

Food Service Facilities have the potential to discharge oil, grease, and other food related wastes into the public sewerage system. Over time these discharges plug the sewers and cause back-ups. The sewage then overflows to the nearest outlets, which could be on a road, in your restroom, or in someone else’s basement. When this happens, costs of clean-up, damages, and repairs can be significant depending on where the sewage overflows. Health and other environmental problems can also arise. Your cooperation in preventing blockages in the sewers will prevent unnecessary costs, public health problems, and environmental damages.

Regulation of Vehicle Maintenance Facilities

Regulation of Vehicle Maintenance Facilities    

Attn: Owners and Managers:              

            In conformance with Federal, State and Local requirements, and to insure proper operation of the public sewerage system, Howard County has established a program to control the discharge of wastes from non-domestic sources to the public sewers. This program will affect motor vehicle fueling, maintenance, and repair establishments. The waste control program is specifically authorized by the Howard County Code, Section 18.122A, entitled “Regulation of Discharges to the Public Sewerage System”. The intent of this regulation is: 

1.       To control fuel, oil, and grease type discharges that have the capability to interfere with the operations of sewage pipelines, pumping stations, or treatment plants.

2.       To control discharges of fuels, solvents, chemicals, etc., that may have the capability to cause a combustible or explosive condition.

3.       To control discharges of chemicals/solvents that have the capability to interfere with biological treatment processes at the sewage treatment plant. 

               The Bureau of Utilities is requesting motor vehicle fueling, maintenance and repair establishments to complete the application (link below) and return it to our office. The purpose of the application is to update information related to your facility size, services, and waste disposal methods.

Frequently Asked Questions ( FAQ's )

What is FOG ?

Fats, Oils, and Grease ( FOG ) are byproducts of cooking and meat cutting. FOG can be found in meat fats, oils, shortening, butter, margarine, sauces, and dairy products.

Why is FOG an issue for me ?

When FOG are poured down drains or in garbage disposals, they build up in our sewer systems and can back up in our sinks, toilets and possibly into your own or somebody else’s basement. These backups pose serious public health and environmental problems – and they can be very costly too. Sewer overflows damage the environment by affecting the health of our waterways. By learning how to safely recycle or dispose of FOG, we are accepting some of the responsibility for the health of our environment and the quality of life we enjoy in Howard County.

What can I do ?

Whenever food is cooked, byproducts ( especially cooking oils and grease ) should NOT be poured down the drain or into garbage disposals. Pans and pots with heavy grease build up should be wiped with a paper towel before being placed in the dish washer.

What about the piping in my house ?

The first pipes that will become blocked with FOG will be your own pipes and that could result in expensive plumbing bills. Keeping FOG out of your drains and the sewer system is good for your home’s plumbing.



Residential Used Cooking Oil Collection Program at Alpha Ridge Landfill

The Howard County Landfill now accepts used vegetable-based cooking oil from residents for recycling. Any type of liquid vegetable oil (i.e., peanut, corn, canola, olive, etc) is accepted. Used cooking oil may be brought to the Alpha Ridge Landfill and left with the attendant at the guardhouse. Please call (410) 313-6444 to arrange an appointment for large quantities.

Please make sure that the cooking oil is not mixed with other fluids ( water, petroleum products, soaps, etc ). Place the cooking oil in a container with a tight-fitting lid, metal or plastic containers are preferable. Do not fill any container while the cooking oil is still hot as this could cause the container to crack or split; let the oil cool down for a few minutes before filling a container.

Vegetable oil that is mixed with small amounts of animal fats can be recycled as long as the amount of added animal fat has not caused the liquid to solidify. The method of collection that is being used can only handle liquids, not solids.

Used cooking oil is recycled into several valuable commodities including industrial fuel, soap, cosmetics, poultry feed, and many more.
