Duncan Oil Properties Inc / Doris 4 12 - Oil Extraction Facility in Anthon, Oklahoma

Duncan Oil Properties Inc / Doris 4 12 is an oil extraction facility located in Anthon, Custer County, Oklahoma, United States. The facility is operational and engages in the extraction of crude petroleum, classified under NAICS code 211120. Oklahoma is a significant oil-producing state, with many small to medium-sized extraction sites contributing to the region's energy output. The facility operates under the regulatory framework of the United States Environmental Protection Agency (EPA) and state-level Oklahoma Corporation Commission (OCC) rules. Oil extraction in the U.S. is subject to the Clean Air Act (CAA) and Clean Water Act (CWA), with specific requirements for emissions control, spill prevention, and produced water management. The facility's scale is typical of many inland extraction sites in the Mid-Continent region. Environmental considerations for oil extraction include potential impacts on local groundwater, air quality from volatile organic compounds (VOCs), and land disturbance. The facility's location in rural Custer County suggests proximity to agricultural land and limited population density, which may influence its operational footprint and regulatory oversight.

The facility is situated in the Anadarko Basin, a region with extensive oil and gas activity. Local environmental concerns include potential groundwater contamination from drilling fluids and produced water, as well as air emissions from flaring and equipment. The rural setting may reduce direct human exposure but requires careful management of surface spills to protect soil and water resources.
