Determining resource quality and potential reasons for impairment of Illinois streams, inland lakes, and Lake Michigan : (Methods used for 2002 305(b) reporting).

According to Section 305(b) of the Clean Water Act (i.e. a generic name that refers to the Federal Water Pollution Control Act of 1972, the Clean Water Act of 1977, and subsequent amendments) and guidance provided by the United States Environmental Protection Agency (USEPA), each state must prepare and submit annually to the U.S. Congress and the USEPA report that describes the resource quality of the surface waters of the state. Every other year, this report, commonly referred to as the "305(b) report," must be provided in written form, whereas in alternate years each state may submit an electronic database to meet the reporting requirement. In the 305(b) report, states must also explain how they determined the resource quality of the waters of the state in terms of the degree to which predefined beneficial uses of those waters are supported. Also, in the 305(b) report when any designated use for any water body is not fully supported, the state must report potential reasons for the impairment. Herein, is explained how the Illinois Environmental Protection Agency determines the resource quality of Illinois streams, inland lakes, and Lake Michigan.

Diesel fuel release at Caterpillar Proving Grounds, East Peoria, Illinois : Tazewell and Woodford Counties /

On February 18, 2011, Caterpillar Tractor Company, Inc. (CAT) was notified by the Woodford County Emergency Management Agency that residents along Ten Mile Creek had noticed a fuel odor. CAT personnel checked outfalls on the bluff below and the Proving Grounds fuel station and discovered some diesel fuel seeping into a ravine which continues to Ten Mile Creek. An initial investigation around the fueling facility revealed a diesel leak in an underground line that feeds the fuel dispensers. Diesel fuel is used on the Proving Grounds property to power the earth-moving equipment being tested there. At the time the leak was found, CAT began excavating to remove the source and to find the extend of the leak. The fuel had followed a down-hill slope to a ravine on CAT property, ran down the ravine and impacted Ten-Mile Creek (about one-half mile away) with a visible sheen of diesel fuel on top of the water.
