Natural Resource Damage Assessment
The Former Indian Refinery Site (the Site) consists of approximately 990 acres located south of the City of Lawrenceville in southeastern Illinois. The area is bounded by residential neighborhoods, cropland, bottomland forested wetlands, the Embarras River, and an unnamed tributary of Indian Creek.
The facility at the Site was active as a petroleum refinery from the early 1900's until the mid-1990's. During its operation, the refinery produced various petroleum products. A variety of waste products were also generated and disposed of or released to various areas on- and off-site, including the floodplain of the Embarras River. Petroleum products and hazardous substances, including an acidic sludge, polycyclic aromatic hydrocarbons (PAHs), benzene, toluene, ethyl-benzene, xylene, cadmium, lead and other metals have been detected in surface water, soils, and in groundwater on or adjacent to the site.
The Site was placed on the National Priorities List (NPL) of uncontrolled hazardous waste sites in 2000 pursuant to the Comprehensive Environmental Response, Compensation and Liability Act, 42 USC 9601 et seq. (CERCLA, also known as Superfund) and is being cleaned up under that authority. Chevron with oversight by The Illinois Environmental Protection Agency (Illinois EPA) is conducting a remedial investigation/feasibility study (RI/FS) to determine the response actions that are required to address human health and ecological risks at the site. For the current status of the remedial investigation/feasibility study visit the Illinois EPA's Indian Refinery site.
The natural resource trustees (the Trustees), which are the Illinois EPA, the Illinois Department of Natural Resources (Illinois DNR), and the U.S. Department of Interior acting through the U.S. Fish and Wildlife Service (Service), are conducting a Natural Resource Damage Assessment (NRDA) for the Site in cooperation with Chevron. In November 2004, the Trustees and Chevron signed a Funding and Participation Agreement to facilitate a cooperative NRDA for the Site. An NRDA Technical Workgroup, consisting of representatives of Illinois EPA and DNR, the Service, and Chevron, was established to conduct the NRDA. The NRDA will be coordinated with the ongoing remedial investigation/feasibility study, the first time such coordination has been formally conducted in the State of Illinois.
Contaminants released into the environment from the Site can cause injuries to natural resources, including surface water, groundwater, soils, air, and biota. The purpose of the NRDA is to determine the amount and type of natural resource restoration that is required to:
Natural resource restoration can include actions that rehabilitate, replace, or acquire the equivalent of the injured natural resources and the services they provide.
In conducting the NRDA cooperatively with Chevron, the Trustees will take advantage of the shared expertise and experience between the two groups to determine the amount of natural resource restoration that is required to make the public whole for the natural resource injuries.
