Anadarko E&P Onshore, LLC (f.k.a. Union Pacific Resources, Enid Refinery, and Champlin Refinery) is a closed, dismantled refinery consisting of 362 acres in the northeast portion of the City of Enid. Past refinery operations included a land treatment unit in which hazardous waste solids were land farmed. The site has a RCRA post-closure permit for the land treatment unit. A benezene plume from past operations is being remediated. Groundwater monitoring occurs semi-annually.

NOTE: some of the permit files may take some time to download because of their size.
