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 (off lease) 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.

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.

PREVIOUS ENFORCEMENT
ACTIONS: None in the past 5 years.

COMPLIANCE STATUS &
RECOMMENDATIONS: In Compliance. Inclement weather conditions were outside of
reliable detection parameters for the use of an OGI camera. The
DAQ conducted a review of the rules requiring recordkeeping
and looked for installation/operation issues onsite. 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. The DAQ was joined by Scout
personnel during the site inspection.

RECOMMENDATIONS FOR NSR: None
