You must notify EGLE if your Large Quantity Withdrawal is installed or put into operation differently than authorized either by the Water Withdrawal Assessment Tool or by a site-specific review.
These differences can include any or all of the following:
- Changing from a direct surface water withdrawal to groundwater or vice versa.
- Changing the location of the withdrawal.
- Changing the top of well screen depth (for a well in a glacial aquifer) or the bottom of the well casing depth (for an open borehole bedrock well) for a groundwater withdrawal.
- Changing from a bedrock well to a glacial well or vice versa.
- Changing the rated pump capacity for the withdrawal.
- Changing the pumping schedule for the withdrawal.
Changing any of the conditions of an authorized Large Quantity Withdrawal may affect whether the authorization is still valid.
What to do if your Large Quantity Withdrawal has changed since authorized
If the original Large Quantity Withdrawal was authorized by the Water Withdrawal Assessment Tool or by a site-specific review, the property owner must:
- Rerun the Water Withdrawal Assessment Tool using revised information for the withdrawal, and
- Notify EGLE of the revisions and the corrected results
