Project Name: Refinery Impacted Private Property, Cheyenne, Wyoming

Date Project Began: July 2006

Date Project Completed: September 2008

Project Description:  Old Horse Pastures, Inc. (OHP) owned property adjacent to the southern and eastern boundaries of the Cheyenne refinery.  The refinery had impacted the adjacent property and, as early as 1988, was ordered by the Environmental Protection Agency (EPA) to complete site investigations and remediation under authorization of the Resource Conservation and Recovery Act (RCRA).   In 2006, Casey Resources, Inc. (CRI) was requested by the legal counsel for OHP to obtain and review the available environmental reports for the refinery.  The available reports and applicable correspondence were obtained from records maintained by the Wyoming Department of Environmental Quality (WDEQ) and numbered in the hundreds.  The review included a detailed assessment of the EPA and WDEQ Administrative Orders of Consent, review of site investigation results, and review of remediation planning documents.  CRI provided comments on the reviewed documents to WDEQ.  In addition, CRI assisted legal counsel with identifying data gaps in the remediation planning including limited interim efforts in areas that continued to impact the adjacent land and stream environments.  Through continued review and comment, CRI assisted OHP to eventually obtain a settlement agreement in which the impacted land area was purchased by the refinery.

Type of Contamination:  Petroleum impacts.
