Part 327 water withdrawal permits and registration
Our Water Use Program manages large water withdrawals in Michigan to help protect our rivers, streams, lakes, and groundwater. If a business, farm, municipality, or other facility plans to pump large amounts of water, it may be considered a Large Quantity Withdrawal.
A Large Quantity Withdrawal is defined as having the capacity to withdraw more than 100,000 gallons per day (GPD) over a 30-day period (70 gallons per minute (GPM)), and includes the combined total for all pumps on the property.
Owners of Large Quantity Withdrawals are required by state law to register the withdrawal or obtain a permit before operating. The Water Use Program reviews proposed withdrawals to make sure they do not significantly alter the local water balance resulting in harm to nearby water resources or aquatic life.
These requirements are part of Michigan’s water protection law and the regional Great Lakes–St. Lawrence River Basin Water Resources Compact, which helps safeguard Great Lakes water across the region.
*Exceptions to water withdrawal permit requirements:
What happens after using the Water Withdrawal Assessment Tool?
The Water Withdrawal Assessment Tool is a screening system that predicts whether a large quantity withdrawal is likely to cause an adverse resource impact to nearby streams or rivers.
- If the proposed withdrawal passes the Water Withdrawal Assessment Tool...
- It can be registered immediately
- The registration receipt produced by the Water Withdrawal Assessment Tool is legal authorization from EGLE to make the withdrawal
- If the proposed withdrawal doesn't pass the Water Withdrawal Assessment Tool...
- A site-specific review can be requested to pursue authorization of the withdrawal.
- A site-specific review is a deeper investigation and analysis performed by EGLE staff that overrides the Water Withdrawal Assessment Tool and often results in a successful registration.
- The property owner also has the option to hire a consultant to submit a third-party analysis instead of a EGLE site-specific review.
- A site-specific review can be requested to pursue authorization of the withdrawal.
