The maximum permitted injection rate for IW-1 shall be 903 gallons per minute and the maximum permitted injection volume for IW-1 shall be 1.3 million gallons per day.
This injection well is monitored by dual-zone monitor well (DZMW-1); which, is completed with an upper monitor zone from 1,614 to 1,664 feet bls and a lower monitor zone from 1,900 to 1,950 feet bls.

The Department has permitting jurisdiction under Chapter 403 of the Florida Statutes (F.S.) and the rules adopted thereunder. The project is not exempt from permitting procedures.
