BURLINGTON INTERNATIONAL AIRPORT April 1, 2019 QUICK TURNAROUND (QTA) RENTAL CAR FACILITY OIL/WATER SEPARATOR 0PERATIONS AND MAINTENANCE MANUAL 3 2.0 GENERAL SYSTEM OVERVIEW All trench drains located inside the new car wash facility, including car wash and potential future maintenance bays, are conveyed to a 6” PVC sanitary sewer pipe which discharges out the south side of the building. Wastewater is then conveyed to the influent side of the new 1,000- gallon oil/water separator (OWS). Interior dimensions of the new 1,000-gallon OWS are 10’-0” long x 5’-0” wide x approximately 4’-0” high. A 6” thick concrete baffle wall separates the influent/sedimentation compartment from the effluent compartment. 2.1 OIL/WATER SEPARATOR SYSTEM CONFIGURATION The OWS is designed with the baffle wall to trap sediment(s) and retain floating oils and grease, while allowing wastewater to discharge. Influent wastewater is first conveyed into the branch side of a 6” PVC tee fitting and then downward into the influent/sedimentation compartment. It is in the influent/sedimentation compartment where sediment falls out of suspension and any oils, grease, or floatables rise to the surface of the tank liquid. Wastewater is then conveyed upward over the baffle wall to the effluent compartment. The wastewater then is directed downward to the flow side of a second 6” PVC tee fitting for effluent discharge out the branch side of the fitting. Discharge from the OWS is to the City of South Burlington, wastewater collection system with treatment at the Airport Parkway Wastewater Treatment Facility. The design invert of the influent pipe is elevation 322.85’, while the effluent pipe invert is set at elevation 322.75’. The difference in the two invert elevations of 0.10’ creates the ‘head’ required to convey wastewater through the OWS. Access and inspection of the OWS is via two – 30” diameter cast iron frames and covers. Each 6” PVC tee fitting noted above are left open at the top for inspection purposes . The tee fittings are connected to the influent and effluent piping with slip flanges for removal if required. Site Utility Drawings, OWS details, and sanitary sewer profiles are presented in Appendix C. BURLINGTON INTERNATIONAL AIRPORT April 1, 2019 QUICK TURNAROUND (QTA) RENTAL CAR FACILITY OIL/WATER SEPARATOR 0PERATIONS AND MAINTENANCE MANUAL 4 3.0 INSPECTION AND MAINTENANCE Regular inspection and maintenance is a proven, cost-effective way to maximize water resource protection for all pollution control practices, and are required to insure proper functioning of the OWS system. Both inspection and maintenance of the OWS system is easily performed from the surface. The OWS has no moving parts, simplifying the inspection and maintenance process. IMPORTANT SAFETY NOTE: Do not enter underground tankage to inspect the OWS system unless all Occupational Safety & Health Administration (OSHA) regulations for confined space entry are followed. Please refer to the following information and guidelines before conducting inspection and maintenance activities. 3.1 INSPECTION FREQUENCY • Post-construction inspection is required prior to putting the OWS system into service. • Routine monthly inspections are recommended during the first year of operation to accurately assess the sediment accumulation. • Inspection frequency in subsequent years is based on the maintenance plan developed in the first year. It is recommended to inspect the OWS quarterly each year at a minimum. • Inspections should also be performed immediately after an oil, fuel or other chemical spill. The OWS system can be inspected through both manhole access covers. Sediment and oil depth inspections are performed with a sediment probe and oil dipstick. Visual observation of the surface water for a colored sheen is also one method for making a preliminary determination for the presence oil. Inspection of the internal piping should also be performed. 3.2 MAINTENANCE AND CLEA NING FREQUENCY For optimum performance, the OWS should be cleaned out once the sediment or sludge depth reaches 6” above the tankage floor. The minimum cleaning frequency is twice annually, although the frequency can be adjusted based on historical inspection results. BURLINGTON INTERNATIONAL AIRPORT April 1, 2019 QUICK TURNAROUND (QTA) RENTAL CAR FACILITY OIL/WATER SEPARATOR 0PERATIONS AND MAINTENANCE MANUAL 5 The OWS should be cleaned out immediately after an oil, fuel or chemical spill. The OWS system can be maintained through both manhole access covers. Insert an oil dipstick into the top of the surface water. If oil is present, pump off the oil layer into a separate container using a small pump and tubing. Maintenance cleaning of accumulated sediment is performed with vacuum truck and trained personnel. Using the vacuum hose, the trained personnel should decant the water from the OWS tankage into a separate containment tank mounted on the vacuum truck. the trained personnel should then remove the sludge from the bottom of the unit using the vacuum hose and re-fill the OWS with water when the cleaning operation is complete. Units that have not been maintained regularly, have surpassed the maximum recommended sediment capacity, or contain damaged components may require manned entry by trai ned personnel using proper confined space entry procedures. 3.3 COMMON PERFORMANCE I SSUES Common performance issues include the following conditions: • If the OWS system is not maintained regularly and fills with sediment and debris beyond its capacity as noted above, sediment removal efficiency may be reduced. • If an oil spill(s) exceeds the oil capacity of the system, subsequent spills may not be captured. • If debris clogs the inlet of the OWS system, removal efficiency of sediment and hydrocarbons may be reduced. • If a downstream blockage occurs, a backwater condition may occur in the system and removal efficiency of sediment and hydrocarbons may be reduced. 3.4 PERSONNEL TRAINING For typical inspection and maintenance activities, no specific supplemental train ing is required for the OWS system. However, the OWS system should be cleaned by professional vacuum cleaning service providers with experience in the maintenance of underground tanks, sewers and catch basins. In unusual circumstances, such as if a damaged pipe fitting needs replacement or some other condition requires manned entry into the vessel, confined space entry procedures must be followed. Only professional maintenance service providers trained in these procedures should enter the vessel. Service provider companies typically have personnel who are trained and certified in confined space entry procedures according to local, state, and federal standards.

Environmental Fact Sheet Oil / Water Separator What is an oil / water separator? Oil/water separators are underground vaults, usually constructed of concrete, installed between a drain or drain network and the connecting sewer pipe. These vaults are designed with baffles to trap sediment(s) and retain floating oils and grease, while allowing water to discharge. The large capacity of these separator systems slows discharge water allowing oil to float to the surface and solid material to settle to the bottom. Who typically needs an oil / water separator? Any business or facility that frequently discharges oily or sediment-laden wastewater to a sewer system should install a separator system. Many local sewer ordinances require an oil/water separator for certain activities such as commercial car washes, vehicle service facilities with floor drains or facilities with a vehicle washing bay. Check with your local town office or contact your wastewater treatment plant operator to see if your town has such a requirement. What is required before an oil / water separator is installed? You should check with your local town office to better understand any local sewer ordinances or requirements that may apply. Before a separator system is installed in an existing facility you need to contact the Department of Environmental Conservation’s regional office serving the area in which your facility is located. In some cases an existing facility may need a permit, and in some cases it may not. A separator being installed in a new facility will require a wastewater permit prior to installation. See the regional office map for the VT DEC to which office serves your town. Plumbing supply contractors or wastewater engineers can be helpful in choosing a separator that is appropriately sized for your facility. Contact your local permit specialist if you have questions about permit requirements for any wastewater activity. How do I know when it needs to be maintained or cleaned? Just because an oil/water separator is still draining, it may not be functioning at its full efficiency. Like any filtration system, an oil/water separator needs to be maintained and cleaned on a regular basis. The efficiency of a separator system is most affected by settled solids or sludge on the bottom of the separator, and by oils floating on the water surface. The VT DEC recommends that an oil/water separator be inspected every six months to a year and the system be cleaned when needed. A separator with less sediments and lower amounts of oil entering the system may only need to be cleaned every few years. Who can I call to pump out and clean my separator system? Oil/water separators can be cleaned by a professional contractor specializing in environmental clean up work. You can contact the Environmental Assistance Office for a list of contractors who do this type of work. These companies have special vacuum trucks that can easily pump materials ranging from liquid, to sludge and dirt slurry. If the liquid is less than 5% by weight petroleum distillates it can be sent to a wastewater treatment facility with approval from the operator. If the solids are less than 5% by weight petroleum distillates they must be land filled. If either the liquid and/or solids contain greater than 5% by weight petroleum distillates they must be properly disposed of as a hazardous waste. Please contact the EAO if you have questions about trying to clean and service your own separator system. Continued► fs_oilwaterseparator.doc• rev. 7/2006 http://www.anr.state.vt.us/dec/dec.htm • 1 of 2 Environmental Fact Sheet: Oil / Water Separator fs_oilwaterseparator.doc• rev. 7/2006 • 2 of 2 What should not go down the drain and into an oil / water separator? Antifreeze, degreasers and detergents can emulsify (break up) oil into small droplets so the oil does not float to the surface. Fuels, alcohols or other solvents can also emulsify oil, as well as cause accumulated vapors, posing a threat to facility employees and/or wastewater treatment plant workers. Concentrated amounts of oily products will decrease the effectiveness of the separator system and require more frequent potentially expensive cleanings. Oil/water separators are not designed to treat heavy metal-bearing wastewater. These types of discharges are typically hazardous waste and must be handled and disposed of accordingly. What can you do to maintain and help keep your oil / water separator clean? You can save maintenance and service costs by minimizing the amount of oil and sediments that enter your system. By frequently sweeping sand and sediments from the floor, you will greatly reduce the potential of those materials building up in your separator. By using drip pans and oil soaking absorbent materials you will greatly reduce the amount of oils and grease that enter your separator. Another way to remove oil is to use absorbent pads and socks on the floor and within your floor drain system. These pads and socks float on water and attract and retain oil allowing the water to pass by. Place them in the inlet chamber or within the floor drain network to trap oils before they have a chance to migrate into the separator system. Check the pads and socks often so they don’t get fully saturated and become less effective. Some pads can be wrung out and reused if handled properly. Remember to properly handle and dispose of any oils that are extracted from such activities, or manage them as used oil if they are not contaminated. After use any such material must be disposed of as oil soaked hazardous waste. See fact sheets for more information.
