Compressor Station
THROUGH: Rik Ombach, Minor Source Oil and Gas Compliance Section Manager
FROM: Paul Bushman, Environmental Scientist
DATE: March 27, 2024
SUBJECT: FULL COMPLIANCE EVALUATION, Minor, Carbon County
INSPECTION DATE: March 20, 2024
SOURCE LOCATION: Remote location
Carbon County, UT
DIRECTIONS: Near Nine Mile Canyon
SOURCE CONTACTS: Glen Hicks, Environmental Contact
O: 832-280-5072, C: 724-263-6199
ghicks@mngllc.com
OPERATING STATUS: Temporarily down due to low natural gas prices.
PROCESS DESCRIPTION: Natural gas is routed into the facility via pipeline. The gas is then
sent through a dehydration unit before being compressed and
routed back into the pipeline. Liquids recovered from the gas are
stored in a 300 bbl condensate tank and a 100 bbl water tank.
Emissions from the storage tanks and vapor collection system
are routed to a flare.

II.A.2 Compressor Engine (E-2)
One (1) compressor engine
Capacity: 290 hp
Fuel: natural gas
Attached equipment: catalytic converter
II.A.3 Natural Gas Dehydrator
One (1) natural gas dehydration unit
Solvent: triethylene glycol
Attached equipment: 1,000,000 Btu/hr boiler and vapor collection system
Fuel: natural gas
II.A.4 Storage Tanks (T-1, T-2, T-3)
Three (3) vertical, fixed-roof storage tanks
Capacity: 12,600 gallons each
Service: natural gas condensates
Attached equipment: tank heaters rated at 125,000 Btu/hr each
Fuel: natural gas
II.A.5 Flare Device
One (1) flare device
Fuel: natural gas or vapor collection system gas
II.A.6 Vapor Collection System
With attached BTEX condenser and flare device
II.A.7 Fugitives from condensate loading
Truck loading
Status: In Compliance. The compressor engine is an Ajax 360LE with SN: 83235. The
dehydrator is a 250 kBtu/hr unit, and there is a 250 kBtu/hr line heater that is used
seasonally. There is one unheated 300 bbl condensate tank, and one unheated 100 bbl
water storage tank. The flare is a TCI 2000.
II.B Requirements and Limitations
II.B.1 The Gate Canyon Natural Gas Compressor Station shall be subject to the following.
II.B.1.a Visible emissions from any stationary point or fugitive emission source associated with the plant
operations or with the control facilities shall not exceed 10% opacity. Opacity observations of
emissions from stationary sources shall be conducted in accordance with 40 CFR 60, Appendix
A, Method 9. [R307-401-8]
Status: In Compliance. No visible emissions were observed from any point during the
inspection.
II.B.1.b The following limit shall not be exceeded:
1,686,300 gallons of natural gas condensates throughput per rolling 12-month period.
[R307-401-8]
4
