Updated: December 2009 Current Status The Oklahoma Department of Environmental Quality (ODEQ) has completed several sampling events of the groundwater. Results show that natural attenuation is taking place through the generation or transformation of related products from the original contaminants. Further investigations conducted by ODEQ and the U.S. Geological Survey (USGS) confirmed that soil conditions are adequate to support the natural attenuation process and the process is taking place. The ODEQ and the USGS have noted that the high levels of sodium, total dissolved solids and chlorides (saltwater or brine) in waters of the upper aquifer make this a Class III or non-potable aquifer. Brine contamination from historic activities associated with oil and gas production in the area has degraded the water quality to such an extent that these aquifers will never meet the criteria for potable water. The ODEQ and EPA continue to monitor the site by conducting Five-Year reviews to verify that the remedy is protective of human health and the environment. The last review was completed in May 2007. In 2008 the ODEQ and EPA prepared a deletion package for this site. A Notice of Intent to Delete was published in the Federal Register on June 13, 2008. The public comment period closed July 14, 2008. One adverse comment was received, a withdrawal notice of the deletion was published in the Federal Register and EPA prepared a response to comments. The site was deleted August 21, 2008. 

### Benefits The selected remedy for the Double Eagle site neutralized and stabilized approximately 44,193 cubic yards of contaminated sludge to protect approximately 32,000 people living within three miles of the site. Approximately 143,465 cubic yards of waste material were hauled and disposed at the East Oak Landfill.

Double Eagle Refinery Company 2 EPA Publication Date: November 30, 2009Double Eagle Refinery Company 3 EPA Publication Date: November 30, 2009 x The Groundwater ROD calls for groundwater monitoring upon completion of source removal.Other Remedies Considered Reason Not Chosen 1. No Action/Limited Action Will not address all risks. 2. On-site stabilization and Capping Not considered permanent due to possible failure of cap. 3. On-site stabilization, Onsite Disposal Was the recommended alternative but State preferred the more economical off-site disposal. 4. On-site Incineration, Does not address metals (primary risk) Onsite capping of ash 5. Off-site Incineration, off site Disposal does not address metals (primary risk)
Other Remedies Considered Reason Not Chosen 1. No Action Will not provide for protection of lower ground water. 2. Pump and Treat Will not reduce overall risk due to possible off-site source and high dissolved solids.
