These products go through a separator where the oil and any water products are sent to storage tanks and the gas is used to power equipment on site (pump jack engine, tank heater, separator, flare, combustor, etc.) Any remaining gas is sent to a pipeline that feeds a local gas plant. The oil and process water in the storage tanks is loaded into tanker trucks and hauled off site for processing and disposal. APPLICABLE REGULATIONS: Utah Administrative Code (UAC) R307-500 Series for the Oil and Gas Industry, and UAC R307-201: Emission Standards: General Emission Standards; and UAC R307-150: Emission Inventories. Federal Subpart: 40 CFR 60 Subpart JJJJ. / + # ) * 0 ' " - 2 SOURCE EVALUATION: Site Type: PBR-Uncontrolled No Flare Controls, Site powered by Engine. DOGM current 12 month rolling production is: 2,072. Utah Statute R307-506 requires a source with throughput greater than 8,000 BBLs to have controls. REGISTERED EQUIPMENT: Tanks, Engine General Provisions Visible emissions are within the following opacity limits: VOC Control Devices and Gasoline engines 0%, Diesel engines 20%, Natural Gas Engines and Boilers, Treater burners & Tank burners 10%, Mobile source dust 10%. [ R307-201-3] In Compliance. No visible emissions were observed at the time of inspection. VOC emissions are, at all times, minimized as reasonably practicable by equipment design, maintenance and operation practices. [R307-501-4(1)] In Compliance. VOC emissions were found properly minimized at the time of inspection. All natural gas-driven pneumatic controllers are in compliance with 40CFR 60.5390 or 60.5390a as applicable. Tagging and record keeping requirements are not required. [R307-502-4] In Compliance. No continuous bleed pneumatic controllers were found on-site at the time of inspection. Tank Truck Loading Truck loading is done by bottom filling or submerged fill pipe [R307-504(1)] In Compliance. Truck loading found properly designed at the time of inspection. Storage Vessels Thief hatches are kept closed and latched. [R307-506-4(1)] In Compliance. Thief hatches found closed and latched at the time of inspection. Vessel Vent Components: (valves, unions, pressure relief devices, etc.) are leak-free, in good repair, and working as intended. (Tank covers are leak free and form a continuous seal.). [R307-501-4] In Compliance. Vessel vent components found leak free and in good working order at the time of inspection. Associated Gas Flaring Associated gas is routed to a process unit for combustion, a sales pipeline or an operating VOC control device, except in an emergency. An emergency release is unanticipated, temporary, infrequent, unavoidable, =24 hrs. and is not due to operator negligence. Low pressure gas from working loss, breathing loss and oil flashing is not "associated gas". [R307-511-4(1)] In Compliance. Associated gas found properly routed at the time of inspection. 3 The following records are kept: The time and date of event Volume of emissions Any corrective action taken for 3 years.[R307-511-5(1)(a)(b)] In Compliance. No associated gas flaring was reported at the time of inspection. Emission Inventory An emissions inventory has been submitted within the past three years. [R307-150-9(1)] In Compliance. This source was found properly reported in the emissions inventory. Oil and Gas Industry Registration Requirement The source is registered with the DAQ. [R307-505-3(3)] In Compliance. Source found properly registered at the DAQ. Registration has been updated within 30 days of a company name change, removal or addition of control devices, or termination of operations. [R307-505-3(3)] In Compliance. Registration found properly updated at the time of inspection. Engine Requirements Affected engine exhaust vents are vertical and unrestricted. Stacks are 8' or greater if the site horsepower rating is 151 to 305 Stacks are 10' or greater if the site horse power rating is 306 or greater. [R307-510-4(3)] In Compliance. Engine on-site predates these regulations. Temporary Emergency Generators, in use for less than 100 days, have an operational hour meter and log book (onsite) recording hours used and maintenance performed. [40 CFR 60 Subpart IIII, JJJJ] In Compliance. No emergency generators were found on-site at the time of inspection.
