62-600.540. Underground Injection

(1) All facilities using Class I wells discharging domestic effluent into Class G-IV waters must meet the secondary treatment and pH limitations specified in subsection 62-600.420(3) and Rule 62-600.445, F.A.C. Disinfection is not required before disposal via any Class I well, whether from any new or existing facility except as provided in subsection 62-600.540(2), F.A.C.; however, all Class I well permittees must maintain capability to disinfect at a level that is consistent with the alternate discharge mechanism pursuant to Rule 62-528.415, F.A.C.

(2) All facilities using Class I municipal injection wells shall meet the requirements of Rules 62-528.440, 62-528.450, and 62-528.455, F.A.C.

(3) All facilities using Class V wells for the injection of reclaimed water to Class F-I, G-I, or G-II ground water for ground water recharge or for salinity barrier control shall meet the requirements of Rules 62-610.550 through 62-610.575, F.A.C.

(4) Reclaimed water aquifer storage and recovery shall meet the requirements of Rule 62-610.466, F.A.C.

(5) Surface equipment for all injection well facilities shall be such that manual backup capability to monitor wellhead pressure and flow is provided for systems utilizing automatic and continuous recording equipment. The design of new facilities and modifications of existing facilities shall incorporate additional surface equipment considerations such that:

(a) Effluent or reclaimed water pumping stations shall be protected from lightning and transient voltage surges. As a minimum, stations shall be equipped with lightning arrestors, surge capacitors or other similar protection devices, and phase protection; and,

(b) Effluent or reclaimed water pumping stations shall be provided with divided compartments to allow access for repair and maintenance purposes without interrupting operation; and,

(c) Potential surge and water hammer will not jeopardize the safety and integrity of the injection well system; and,

(d) Surface equipment for multi-well systems provides operational reliability and flexibility in the event of damage to or failure of the pipeline or a well; and,

(e) Access to the well for geophysical logging without major modifications is enabled; and,

(f) The wellhead shall be protected in a manner to minimize accidents or vandalism; and,

(g) Necessary screening for floatable solids prior to injection to avoid plugging of the formation is provided; and,

(h) Equipment with sufficient reliability and redundancy is provided in accordance with appropriate references contained in subsection 62-600.300(4), F.A.C.

(6) All facilities injecting reclaimed water or effluent to underground injection wells shall comply with the permitting requirements of Chapter 62-528, F.A.C.
