If a proposed withdrawal doesn't pass the Water Withdrawal Assessment Tool, a site-specific review can be requested from EGLE or, alternatively, a third-party analysis can be submitted by the property owner to EGLE to pursue authorization of the withdrawal.
Both the site-specific review and the third-party analysis are deeper investigations performed by professionals which can override the Water Withdrawal Assessment Tool, often resulting in a successful registration.
Starting the third-party alternative analysis
A property owner can hire a professional hydrologist or hydrogeologist to submit an analysis of a proposed Large Quantity Withdrawal with a capacity of up to 1,000,000 gallons per day (694 gallons per minute) instead of requesting EGLE to do the analysis under a site-specific review.
All analyses must determine the likelihood of an Adverse Resource Impact occurring as a result of the proposed withdrawal as defined and required by Part 327, Great Lakes Preservation, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended (NREPA).
