PLACE:	Miami-Dade Water and Sewer Department, located at 13071 Southwest 38 Avenue, Miami, Florida 33146.

Subject:	To obtain public comments on the draft injection well permit for Miami-Dade Water and Sewer Authority Department, who applied on October 5, 2017, for a permit to operate an injection well (File No. 061787-043-045-UC/1M, WACS ID No. 57046). The project is located at the South District Wastewater Treatment Plant (WWTP), 8950 Southwest 232nd Street, Cutler Bay, Florida 33190, in Miami-Dade County, and will consist of three new non-hazardous Class I injection wells, IW-18, IW-19, and IW-20, and operationally test those wells for the disposal of secondary treated municipal effluent which has received high-level disinfection from the Miami-Dade South District WWTP. Wells IW-18, IW-19, and IW-20 are to be constructed with a 24-inch steel diameter casing set to 2,400 feet below land surface (bls) and total depth of 3,200 feet bls completed into the Oldsmar Formation. The maximum injection volume for each injection well is to be 18.65 million gallons per day (MGD). Three single-zone monitor wells, FA-18, FA-19, and FA-20, will be constructed for this project. The monitor interval for monitor wells FA-18, FA-19, and FA-20 is from 980 to 1,090 feet bls. Under this permit all zones of existing monitor wells BZ-1, FA-10, FA-15, and FA-16 and the lower zones of FA-1, FA-3, and FA-4 are to be plugged and abandoned. Single-zone monitor wells FA-1, FA-3, and FA-14 and regional dual-zone monitor well CHI, along with the three-new single-zone monitor wells FA-18, FA-19, and FA-20 are proposed for monitoring this site. ALSO, TO BE CONSIDERED: To obtain public comments on the draft injection well permit for Miami-Dade Water and Sewer Authority Department, who applied on November 17, 2017, for a permit to operate an injection well (File No. 0317749-006-012- UC/1M, WACS ID No. 101237). The project is located at the Miami-Dade Central District WWTP (MDCDWWTP), 3989 Rickenbacker Causeway, Virginia Key, Florida 33149, in Miami-Dade County, and will consist of seven new non-hazardous Class I injection wells (CDIW-3 through CDIW-9) and associated monitor wells (CDMW-2 through CDMW-5), and operationally test those wells for the disposal of secondary treated domestic wastewater with high-level disinfection from the MDCDWWTP. The maximum injection rate for each injection well will not exceed 18.65 MGD. The injection wells are proposed to be constructed with a 24-inch diameter casing set to 2,650 feet bls and total depth of 3,200 feet bls. The dual-zone monitor wells are proposed to be completed in the Floridan aquifer from 1,125 to 1,175 feet bls and from 1,650 to 1,700 feet bls.
