law requiring power plants to report the release of radioactive contaminants into the soil, surface water or ground water to the state within 24 hours. Before the law was passed, companies operating nuclear plants were only required to report such releases to the federal NRC. The law was introduced by Illinois State Representative Careen Gordon and State Senator Gary Dahl, and was signed by Illinois Governor Rod Blagojevich on June 11, 2006 and became effective immediately upon his signature. The state government only found out about the tritium releases at the Exelon-owned plants after local officials near the Braidwood plant informed them. Following that revelation, other information about spills at Braidwood, Byron, and Dresden came to light. The state of Illinois contended that it was not informed of the leaks by Exelon in a timely manner. The law also required all Illinois nuclear power plants to submit to quarterly inspections by the IEPA and the Illinois Emergency Management Agency. Safety As of the second quarter of 2007, Byron Nuclear Generating Station scored in the "green" in every Nuclear Regulatory Commission (NRC) inspection category but one. The NRC has four levels of inspection findings; the levels are color-coded and the colors equate with risk levels. Green inspection findings represent very low risk significance. Higher levels, from white, to yellow, to red, show increasing levels of risk. For any inspection findings greater than green, the NRC conducts follow-up inspections. Unit One scored "green" in every category, while Unit Two scored "white", a step down from "green", on the inspection of the heat removal system. The inspection covered several other significant areas, including unplanned scrams, the alert and notification system and the emergency AC power system. From 2001–2005, no inspections of Byron Nuclear Generating Station found any condition that merited a greater than "green" designation, during the same time period inspection found 71 green conditions at the Byron plant. Byron, like most U.S. nuclear plants, has been the subject of various actions by the NRC. Escalated Enforcement Actions represent one type. From 1997–2007 the Byron plant has received five such actions, two of which resulted in a total of $150,000 in fines. A $100,000 fine was issued on February 27, 1997 due to problems with excessive silt build up in two separate locations at the Byron facility; the NRC fined the plant $50,000 for each problem. The NRC levied an additional $55,000 in
