EPA v. CHEVRON USA INC

Case summary

On November 1, 2006 U.S. EPA Region 5 issued an Administrative Order on Consent for Cleanup of Groundwater at the former Chevron refinery located near Hooven, Ohio west of Cincinnati. The final remedy calls for source control through periodic high-volume pumping of groundwater in targeted areas to extract LNAPL. Monitored Natural Attenuation will also be conducted. Groundwater will be tested regularly and institutional controls put in place to prevent groundwater use at the facility and construction of basements on Chevron property. A system to collect vapors from beneath the adjacent residential areas will continue to operate, and the river bank will be stabilized to prevent the erosion of contaminated material into the Great Miami River. Contingency plans are in place if performance measures are not met. A workplan is due in 120 days from November 1, 2006.
