Fla. Admin. Code Ann. R. 62-610.562 - Salinity Barrier Systems

(1) Reclaimed water may be used in compliance with this rule to create fresh water barriers to impede landward or upward migration of salt water into Class F-I, G-I, or G-II ground waters.

(2) If rapid-rate land application systems are used to create such barriers, the requirements in Part IV of this chapter shall apply. Rapid-rate land application systems are not subject to regulation under Part V of this chapter.

(3) Except as provided in subsection 62-610.562(4), F.A.C., if injection systems are used, the requirements of Rule 62-610.560, F.A.C., shall apply.

(4) Salinity barrier systems involving injection to Class G-II ground water containing 1000 to 3000 mg/L of total dissolved solids. Treatment requirements specified in subsection 62-610.560(3), F.A.C., shall apply to this case, if all of the following conditions are met:

(a) In the engineering report, the applicant provides an affirmative demonstration that the receiving ground water within 1, 000 feet of the salinity barrier injection well is not currently used as a source of public water supply and that the receiving ground water within this area is not reasonably expected to be used for public water supply in the future.

(b) In the engineering report, the applicant provides an affirmative demonstration of the need to control the landward or upward migration of salt water and the ability of the proposed project to retard the landward or upward migration of salt water.

(c) A setback distance of 1, 000 feet shall be maintained from the injection well to potable water supply wells.

(d) The injection system shall be designed and operated to preclude movement of the injected reclaimed water to potable water supply wells with subsequent withdrawal of reclaimed water at the potable water supply wells.

(e) The zone of discharge shall not extend into zones having TDS concentrations less than 1000 mg/L (based on the initial TDS characterization in the initial engineering report and information submitted after the submittal of the initial engineering report).

(5) The Department shall approve less restrictive discharge limitations for parameters which are included as drinking water standards in either of the following circumstances:

(a) An aquifer exemption has been granted, as provided in subsection 62-528.300(3), F.A.C.

(b) A parameter exemption has been granted, as described in Rule 62-520.500, F.A.C.

(6) If the Department establishes alternative discharge limitations in accordance with subsection 62-610.560(5), F.A.C., the alternative limit shall be applied as a single sample maximum.
