A debate took place yesterday on an e-mail list over whether a major water withdrawal request made by Genesee County, Michigan is a 'test' of the Great Lakes Compact or Michigan's new water withdrawal law. One of the most interesting comments was from an observer who said she "failed to see what this has to do with the Compact given that all of Michigan's water comes from the Great Lakes Basin." But the Compact says that within 5 years all proposed consumptive uses of 5 million gallons per day or more are subject to prior notice and regional review. There is no exception for Michigan. The Genesee County proposal is for 8.5 million gallons per day. Whether it's a consumptive use is another matter. Ultimately, some large water withdrawal proposals in Michigan will be covered by some of the Compact's provisions.
