PROCESS DESCRIPTION: Oil and gas products are brought to the surface. 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: SOURCE EVALUATION: Site Type: PBR-Controlled Controlled by flare, Site powered by Line power. The source registered: 3,199 Estimated Oil BBL. DOGM current 12 month rolling production is: DOMG rolling 12 month. 2,913 BBL's. Utah Statute R307-506 requires a source with throughput greater than 8,000 BBLs to have controls. , - 2 REGISTERED EQUIPMENT: 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 during evaluation. VOC emissions are, at all times, minimized as reasonably practicable by equipment design, maintenance and operation practices. [R307-501-4(1)] In Compliance. Source has a combustor and is operating to manufactures 95% destruction specifications. 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. This source does not use continuous bleed controllers as described in 40 CFR 60.5390(a). Associated Gas Flares Any flare has an operational auto-igniter and a continuously burning pilot flame. [R307-503-4] In Compliance. Auto Igniter in place and operating as designed. Flare inlet lines are equipped with a fire arrestor, pressure gauge, inlet pressure regulating valve and other components according to the engineering design, the manufacturers specifications or good practices for safety and emissions control. [R307-501-4(1)]] In Compliance. In place and operating per manufactures design. Tank Truck Loading Truck loading is done by bottom filling or submerged fill pipe [R307-504(1)] In Compliance. The truck loading valves were built and designed for submerged loading. A vapor capture line is used during truck loading if subject to storage vessel emissions controls of R307-506-4(2). [R307-504-4(2)] In Compliance. In place and appears operational during inspection. Storage Vessels Thief hatches are kept closed and latched. [R307-506-4(1)] In Compliance. All hatches were found closed and latched down at the start of the evaluation. VOCs from storage vessels are recycled, recovered or controlled by a device that is compliant with R307-508. Exempt if <8000 bbls crude oil per year, <2000 bbls condensate, or if uncontrolled emissions are <4 tons VOC per year.[R307-506-4(2)(a)] In Compliance. Properly installed and appears to be functional to design. 3 Combustors and VOC Control Devices Air pollution control equipment is installed appropriately, maintained and operated, pursuant to the manufacturers specifications, to control emissions. [R307-501-4(2)] In Compliance. All necessary components properly in place and operating to manufactures specifications. Vessel vent lines are sloped away from the flare inlet or to a separation vessel (scrubber). [R307-501-4(2)] In Compliance. Properly installed and appears to be functional to design. Combuster inlet lines are equipped with a fire arrestor, pressure gauge, inlet pressure regulating valve and other components according to the engineering design, the manufacturer's specifications or good practices for safety and emissions control. [R307-501-4(2)] In Compliance. All necessary components properly in place and operating to manufactures specifications. Air pollution control equipment is designed and sized to achieve the destructive efficiencies in rules and to handle fluctuations in emissions. [R307-501-4(2)] In Compliance. Source has a combustor and is operating to manufactures 95% destruction specifications. The VOC control device(s) required by R307-506 or R307-507 has a control efficiency of 95% or greater, operates with no visible emissions and has a continuously burning pilot flame and an operational auto-igniter according to R307-503. [R307-508-3(1)] In Compliance. Combustor operating correctly with no observed opacity. 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 source has a source specific emissions monitoring plan. [R307-509-4(1)(a)] In Compliance. Reviewed at local field office. Oil and Gas Industry Registration Requirement The source is registered with the DAQ. [R307-505-3(3)] In Compliance. Source appears to be in order. 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. Source appears to meet this requirement. 4 Records for each of the following are kept for three years: Monthly storage vessel vent system inspections (openings, thief hatches, pressure relief devices, bypasses, etc.), if controlled. Monthly crude oil throughput Emission calculations, actuals and sampling data when used to justify an exemption to storage vessel rules Emergency storage vessel usage (dates used, emptied, and volumes), if not controlled. [R307-506-5] In Compliance. Records observed at local field office and appear to be orderly and complete. Applicable Federal Regulations In Compliance. PREVIOUS ENFORCEMENT ACTIONS: None in the past 5 years. COMPLIANCE STATUS & RECOMMENDATIONS: In regards to the site, the overall status is: In Compliance. The DAQ was joined by Ovintiv personnel during the site inspection. OGI camera was used during evaluation, no fugitive emissions were detected. Source was clean and well kept. DAQ recommends frequency of inspections to increase. Source is controlled and oil production is only at 2,913 BBL. RECOMMENDATION FOR NEXT INSPECTION: DAQ recommends for next inspection to observe if combustor equipment is still in operation mode. RECOMMENDATIONS FOR NSR: None. ATTACHMENTS: None.
