ONEOK - SUB-04 STATION: Oil Extraction Facility in Liberal, Kansas

ONEOK - SUB-04 STATION is an oil extraction facility situated in Liberal, Kansas, within Seward County. The facility is part of ONEOK's midstream operations, which focus on gathering, processing, and transporting natural gas and natural gas liquids. Located in the Hugoton Basin, a major natural gas producing area, the station plays a role in the region's energy infrastructure. The facility operates under U.S. federal and state regulations, including EPA standards for oil and gas extraction (e.g., New Source Performance Standards for volatile organic compounds) and Kansas Corporation Commission rules for well operations. Typical oil extraction facilities in this region involve wellhead separation, storage tanks, and pipeline connections. The NAICS codes 211111 (Crude Petroleum Extraction) and 211120 (Natural Gas Liquid Extraction) indicate the facility handles both crude oil and natural gas liquids. As a midstream asset, the station contributes to the efficient movement of hydrocarbons from production sites to processing plants and markets. Its location in southwestern Kansas places it within a network of pipelines and storage facilities that support the broader U.S. energy supply chain. The facility's operational status underscores its ongoing role in regional oil and gas activities.

The facility is located in the High Plains region of Kansas, an area with semi-arid climate and agricultural land use. Oil extraction operations can pose risks of soil and groundwater contamination from spills or leaks of produced water and hydrocarbons. Regulatory oversight includes EPA's Spill Prevention, Control, and Countermeasure (SPCC) rules and state-level groundwater protection programs. The proximity to the Ogallala Aquifer, a critical water source, heightens the importance of containment and monitoring measures.
