State of Florida Department of Environmental Protection Notice of Draft Permit The Department of Environmental Protection hereby provides notice that it has prepared a draft permit for the proposed project as detailed in the application, subject to the conditions specified in the draft permit and summarized below. The applicant, Miami-Dade County, Water and Sewer Department (WASD), Jay J. Fink, Director of Water and Sewer, 3071 Southwest 38th Avenue, Suite 521, Miami, Florida 33146 applied on October 1, 2025, for a Class I injection well operation permit. The project is located at South District Wastewater Treatment Plant, 8950 Southwest 232nd Street in Unincorporated Miami-Dade County, Florida (File 061787-068-084-UO/1M, WACS ID 57046). The permittee will operate seventeen, non-hazardous Class I injection wells (IW-1 through IW-17) for the disposal of municipal wastewater from the South District Wastewater Treatment Plant that has been treated through secondary and high-level disinfection processes. The injection wells are each constructed with 24-inch, outside diameter injection casings set at various depths ranging from 2,392 to 2,746 feet below land surface (bls), and total drilled depths ranging from 2,824 to 3,193 feet bls. The maximum injection rate for injection wells IW-1 through IW-17, except IW-5, shall be 12,949 gallons per minute (gpm) per well, and the maximum injection volume for wells IW-1 through IW-17, except IW-5, shall be 18.65 million gallons per day (mgd) per well at a peak, hourly flow velocity of 10 feet per second (fps) in the injection casing of each well during normal operation. The maximum injection rate for IW-5 shall be 8,837 gpm and the maximum injection volume shall be 12.72 mgd at a peak, hourly flow velocity of 10 fps in the injection casing during normal operation. The injection well system at this facility includes single-zone monitor wells FA-1R, FA-3R (currently under construction), FA-14, FA-17, FA-18, and FA-19, which are completed in the Floridan aquifer with monitor zones ranging from approximately 980 to 1,090 and 1,490 to 1,575 feet bls. A regional, dual-zone monitor well (CHI) is completed in the Floridan aquifer with monitor zones at 1,402 to 1,430 feet bls and 1,700 to 1,770 feet bls. Three other injection wells (IW-18, IW-19, and IW-20) for the disposal of secondary and HLD-treated municipal wastewater have also been constructed at this facility under separate injection well permits. The Department has permitting jurisdiction under Chapter 403 of the Florida Statutes and the rules adopted thereunder. The project is not exempt from permitting procedures. The Department has determined that an Underground Injection Control permit is required for the proposed work. Any interested person may submit written comments on the draft permit and may request a public meeting within 30 days after publication of this public notice. A request for a public meeting shall be submitted in writing and shall state the nature of the issues proposed to be raised in the meeting. If a public meeting is later scheduled, there will be another 30-day notice period for that meeting. Written comments or a public meeting request shall be submitted to the Department of Environmental Protection, Aquifer Protection Program, 2600 Blair Stone Road, MS 3530, Tallahassee, Florida 32399-2400, which is the office processing this permit application. All comments received within the 30-day period will be considered in formulation of the Department's final decision regarding permit issuance. The files associated with this order are available for public inspection during normal business hours, 8 a.m. to 5 p.m., Monday through Friday, except state holidays, at the Department of Environmental Protection, Southeast District, and at the Department of Environmental Protection, Aquifer Protection Program office in Tallahassee.
