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 ZZZZ. # - $ . ) . ) 2 SOURCE EVALUATION: Site Type: PBR – Uncontrolled No Flare Controls, Site powered by Engine. DOGM current 12 month rolling production is: 657 BBLs. Utah Statute R307-506 requires a source with throughput greater than 8,000 BBLs to have controls. REGISTERED EQUIPMENT: Engine - Natural Gas 2-Stroke Lean Burn Make - Ajax Model - E-42 Mfg Year - 1960 Horse Power - 40 Combustion - Natural Gas, Pneumatic, Tank 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 detected by use of the USEPA Method 9. VOC emissions are, at all times, minimized as reasonably practicable by equipment design, maintenance and operation practices. [R307-501-4(1)] In Compliance. Associated gas is routed to a sales gathering line. Tanks all have thief hatches and PRV's that are closed and not leaking. The expected components were found installed. 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. The natural gas-driven pneumatic controllers at this source are not continuous bleed but are low-bleed or snap acting.

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] Not Observed. It was too windy during the evaluation to operate the camera with any certainty. 3 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 is gathered to a sales line. 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 reported venting events or breakdowns. Emission Inventory An emissions inventory has been submitted within the past three years. [R307-150-9(1)] In Compliance. The operator submitted for the 2020 emissions inventory. The results for the 2023 inventory have not yet been released. Oil and Gas Industry Registration Requirement The source is registered with the DAQ. [R307-505-3(3)] In Compliance. 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.
