Site History and Background
In September 1972, Royal N. Hardage opened and began operating an industrial hazardous waste land disposal facility. Initially, the facility was permitted by the Oklahoma State Department of Health, but the permit was later revoked when it failed to meet newly established Environmental Protection Agency standards. EPA investigations and inspections indicated poor waste management practices that posed a potential threat to human health and the environment. On behalf of the EPA, the U.S. Department of Justice filed a lawsuit, which sought closure and recovery of the site. Royal Hardage was then forced to file for bankruptcy and close the site in September 1980. During site operations, approximately 21 million gallons of acidic, causticm and corrosive wastes were disposed on the site. Initially, liquid and sludge waste from drums or tank trucks were discharged into unlined pits. As the disposal pits filled, drums were piled into a sludge mound in the center of the property. Eventually, the site contained waste impoundments, including a large unlined main pit, a series of smaller pits, a sludge mound, and a barrel mound.
The cleanup for the Hardage/Criner Site included:
- Composite cap placed over former disposal area to prevent direct contact with waste, control surface water flow, limit erosion of affected soils, and to reduce infiltration
- Permanent Mounds Liquid Recovery System functions to extract non-aqueous phase liquids, which are sent off-site for destruction
- Three groups of ground water wells monitor natural attenuation of the alluvial aquifer
- Passive Aeration System treats contaminated ground water collected by the V-Trench and discharges into an on-site polishing basin (Green Remediation Technique)
- Control of air emissions from source areas
All immediate threats at the site have been addressed, and the selected remedies are expected to remain protective of human health and the environment. The Hardage/Criner Site Remedy is currently in the Operation & Maintenance phase.
Did You Know?
The Hardage Site is under the continuing jurisdiction of the U.S. District Court for the Western District of Oklahoma and operates under a Court ordered remedy, not an EPA CERCLA Record of Decision.
Land Use Restrictions
Historical land use surrounding the site is primarily agricultural. Institutional controls in the form of a deed notice restrict use of the site, its ground water, and some neighboring properties. On going cleanup activities and remaining waste complicates any reuse. There is currently a security fence along the perimeter of the site. Recent modifications to the institutional control boundaries now allow livestock grazing south of the site.
Sources of Contamination: 278,000 cubic yards of sludges, waste drums, tank trucks, highly contaminated soils, and waste liquids contained in three waste disposal areas near the center of the property
Contaminants of Concern: Acids, alcohols, caustics, metals, pesticides, solvents
Surface Water Impacted: North Criner Creek
Ground Water Impacted: North Criner Creek Alluvial Aquifer
