IntroductionThe State of Oregon and the Oregon Department of Environmental Quality have developedthis calendar for use by Oregon gasoline dispensing facilities to assist in compliance withvapor balance requirements. This calendar provides general information and tools. Pleasenote that official and full language of all applicable OAR and permit conditions is the actualenforceable language. A copy of your permit should always be available on site.Specific vapor recovery/balance rules, regulations, and permitting are available via OregonAdministrative Rules and Air Contaminant Discharge Permits. OAR 340-244 and OAR 340242 contain gasoline dispensing facility specific rules and regulations. Air ContaminantDischarge Program general permit 22 (stage one) and 23 (stage two) contains gasolinedispensing facility specific permit v/deq/aq/aqPermits/Pages/ACDP-General.aspxRequest assistanceDEQ’s small business assistance program provides industry with written information andtechnical assistance visits which clarify requirements and explains how to stay in compliancewith air pollution rules and regulations.

What is vapor balance?Vapor balance equipment is also referred to as stage one. Gasoline vapor balance systemscontrol gasoline vapors created and displaced during the storage and transfer of gasoline tostorage tanks. These systems allow a delivery vehicle (tanker) to capture gasoline vapors whileloading fuel into storage tanks.What is vapor recovery?Vapor recovery equipment is also referred to as stage two. Gasoline vapor recovery systemscapture vapors that may be released to the environment during gasoline dispensing fromstorage tanks. These systems capture gasoline vapors at the dispensing point.Why do we need vapor recovery systems?The recovery of volatile organic compounds from gasoline dispensing facilities provides asignificant reduction in the formation of ground level ozone. The hazardous air pollutantsemitted from gasoline dispensing facilities include benzene. Exposure to benzene may causecancer and have other harmful effects to human health. Vapor recovery equipment is designedto capture and recycle these emissions and when it is maintained in peak operating condition,the environment and human health will be enhanced. As the owner or operator of a dispensingfacility engaged in the distribution of gasoline, you can contribute greatly to the reduction ofthese health concerns.How does a vapor recovery system work?Certified vapor recovery systems include hoses, nozzles, and other equipment that creates apath which returns gasoline vapor back to the underground storage tank. This system ofcontrols and equipment is designed to capture vapor before it is released into the atmosphere.Image SourcePotter, Z., Thomas, E., Whitener, V., & Konopaski, K. (2015).

Performing inspections of your facility equipmentYour Stage I equipment may include: dust caps,poppet valves, submerged fill tubes, spill buckets,swivel adaptors, and PV valves.Dust Cap Seal/Gasket in place and in good condition?Cap fits snugly and closes securely on all tankopenings?Spill Containment BucketFree of liquid and debris?Poppet Valve AKA Dry Break (Dual point)Does the spring movement open and then return to aclosed/sealed position when depressed if you have it?Vapor Return Swivel Adaptor Ensure the Adapter isnot damaged or loose.Dual Point vs. Single PointSome facilities have a dual point system. This type of system has one liquid fill line and one vapor return line(two openings per storage tank). A delivery vehicle will attach two hoses to your equipment for a delivery. Thephotographs above are both from dual point systems. Single point, or coaxial, Stage I equipment has one linethat is used for liquid filling and vapor return simultaneously. These single point systems do not have a poppetvalve. (Note: If you are required, based on throughput, to conduct PD and PV testing a new tank install mustbe dual point.)Single Point – If your facility has a single point Stage I system thetank would look similar to this one. One opening in the tank allowsfor both vapor return and liquid filling. Ensure the gasket seal is ingood condition, the cap fits snugly and creates a good seal, and allspill containment buckets are free of liquid and debris.If you have questions as to whether equipment needs to bereplaced, repaired, or what is required please contact DEQ fortechnical assistance. Help can be provided in making adetermination.State of Oregon Department of Environmental Quality4

Vacuum-Assist vs Balance SystemThe Vacuum-Assist system use a vacuum pump to pullvapors back to the underground tank. The vacuum can begenerated by either an electric vane pump or a venturedevice such as the Healy mini-jet that uses pressurizedgasoline to produce a vacuum.The Balance System transfers vapors from the vehicletank back to the station without the assistance of anexternal force. The key feature in the balance system isa hose nozzle that makes a tight connection without thefill pipe on the vehicles gasoline tank.State of Oregon Department of Environmental Quality5

Performing inspections of your facility equipment continuedYour Stage II equipment may include: nozzles, hoses, breakaway connectors, and breakaway hoses (whiphoses).Vacuum Assist System ExampleWhip HoseHose in good condition? Free from tears and cracks? (Thishose comes from the dispenser to the breakawayconnector)Breakaway connectorInstalled in the correct direction? No leakage?NozzleFree from signs of leakage everywhere?Dispenser HoseHose in good condition? Free from tears and cracks?Check entire length of hose.*It is helpful to bend or move the hose while you inspectyour equipment to better notice cracks or tears.Balance system exampleBreakaway connectorInstalled in the correct direction? Free from signs of leakage?Dispenser hoseHose in good condition? Free from tears andcracks? Make sure hose is not flattened for more than 5”-6”.Check entire length of hose.Whip hoseHose in good condition? Free from tears and cracks?

BellowsReplace for slits longer than 1”.Replace for triangular tears longer than ½”. Replace faceplateif damaged more than 1/4 of circumference.*It is helpful to bend or move hoses and bellows better exposecracks and tears.State of Oregon Department of Environmental Quality7

Note that one PV valve is acceptablefor multiple gasoline tanks if the piping ismanifolded together. All Stage II permittedsites require PV valves for gasoline storagetanks.If you have questions as to whether equipment needs to be replaced, repaired, or what isrequired please contact DEQ for technical assistance.
