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: 40 CFR 60 Subpart JJJJ. , - 2 SOURCE EVALUATION: Site Type: PBR-Uncontrolled Controlled by flare, Site powered by Engine. The source registered: 557 Estimated Oil BBL. DOGM current 12 month rolling production is: 289 BBL's.. Utah Statute R307-506 requires a source with throughput greater than 8,000 BBLs to have controls. REGISTERED EQUIPMENT: Engine - Engine - Natural Gas 2-Stroke Lean Burn Make - Ajax Model - E-42 Mfg Year - 1967 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 excessive opacity limits were observed 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 meets uncontrolled requirements. All other internal components of tank battery functioning as designed. 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.

Storage Vessels Thief hatches are kept closed and latched. [R307-506-4(1)] In Compliance. All hatches were found closed at the start of the evaluation. Natural Gas Engines 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. Meets this requirement. Pre-2016 source. 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 found properly routed to pipeline at the time of inspection. Oil and Gas Industry Registration Requirement The source is registered with the DAQ. [R307-505-3(3)] In Compliance. Source appears to be properly registered at the time of inspection.

Source appears to meet this requirement. Applicable Federal Regulations NSPS (Part 60) JJJJ: Standards of Performance for Stationary Spark Ignition Internal Combustion Engines [40 CFR 60 Subpart JJJJ] In Compliance. Source appears to meet this requirement. PREVIOUS ENFORCEMENT ACTIONS: None in the past 5 years. COMPLIANCE STATUS & RECOMMENDATIONS: In regards to the site, the overall status is: In Compliance. This source was found to be clean and well-kept with no visible or fugitive emissions. The source was inspected by AVO and with an OGI camera and found to be free of leaks. The operator's representatives were pleasant and cooperative. Requested records were provided in a timely manner and reviewed at the local field office. RECOMMENDATION FOR NEXT INSPECTION: The DAQ has no recommendations for the next inspector other than what are customary. RECOMMENDATIONS FOR NSR: None. ATTACHMENTS: None.
