So far there aren't many dates but I also found this,
http://www.barr.com/clientre/Archives/UtilityMACT2.asp the guy gets blamed if he does it or not, I like to find out who started it before I blame.
From what I could find it was signed into law in 90, IMO all these politicians sign stuff that may appease someone at the time & never look into the consequences on down the road. Guess they figure they will be long gone & someone else will get the blame & the whole time it's the tax payer that suffers.
