ROCKDALE, Ill. (AP) - The Environmental Protection Agency is reviewing Caterpillar Inc.'s oil spill control and monitoring plans after 65,000 gallons of oil overflowed, some spilling into the Des Plaines River.

The federal EPA said in a release Wednesday that most of the cleanup from the Feb. 8 spill near Joliet has been completed. The EPA says any consequences that result from its review of Peoria-based Caterpillar will be announced later.

Caterpillar says in a statement that it's working with the EPA and the Coast Guard.

The EPA says state and federal authorities found no significant impact from the spill on wildlife and ecological resources.

According to the agency, a pair of waste oil collection pits overflowed and spilled into the river and onto an embankment and gravel parking lot.
