Notice of Intent
The Department of Environmental Protection hereby provides Notice of Intent to Issue a 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, Miami-Dade Water and Sewer Department, Jay J. Fink, Director of Water and Sewer, 3071 Southwest 38th Avenue, Suite 521, Miami, Florida 33146 applied on March 28, 2025, for a construction permit for a Class I injection well system. The project is located at the North District Wastewater Treatment Plant (WWTP), 2575 Northeast 156th Street, North Miami, Florida 33160, in Miami-Dade County (File 0057792-035-039-UC/1M, WACS ID 56453).
The permittee will operationally test five, non-hazardous Class I injection wells (IW-5N, IW-6N, IW-7N, IW-8N, and IW-9N) that have been constructed for the disposal of high-level disinfected domestic (municipal) wastewater from the North District WWTP.
The injection wells are constructed with 24-inch outside diameter injection casings set to depths ranging from 2,635 to 2,785 feet below land surface (bls). Each well has been drilled to a total, open-hole depth of 3,300 feet bls.
The maximum injection rate and volume for each injection well shall be 12,951 gallons per minute per well and the maximum injection volume shall be 18.65 million gallons per day per well at a peak, hourly flow velocity of 10 feet per second in the injection casing of each well during operational testing. Operational testing of IW-5N, IW-6N, IW-7N, IW-8N, and IW-9N will not commence until construction of the HLD processes are completed at the North District WWTP.
Operational testing of the five injection wells will be monitored by dual-zone monitor wells MWFA-5N and MWFA-6N. The monitor wells are completed in the Floridan aquifer with upper monitor zones at approximately 1,100 to 1,200 feet bls and lower monitor zones at 1,440 to 1,500 feet bls.
Four other injection wells (IW-1N, IW-2N, IW-3N, and IW-4N) for the disposal of secondary treated municipal wastewater and four associated monitor wells (FA-1R, FA-2N, FA-3N, and FA-4R) are currently operating at this facility under separate UIC permits.
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. The Department has determined that an Underground Injection Control permit is required for the proposed work.
The Department will issue the permit unless a petition for an administrative hearing is timely filed under Sections 120.569 and 120.57, F.S., before the deadline for filing a petition. On the filing of a timely and sufficient petition, this action will not be final and effective until further order of the Department. Because the administrative hearing process is designed to formulate final agency action, the hearing process may result in a modification of the agency action or even denial of the application.
Petition for Administrative Hearing
A person whose substantial interests are affected by the Department's action may petition for an administrative proceeding (hearing) under Sections 120.569 and 120.57, F.S.
