Current through Reg. 50, No. 138; July 16, 2024
(1) The
				following operating standards shall apply to all Limited Use Public Water
				Systems:
(a) All components shall function
				properly at all times.
(b) Should
				the system shut down, the supplier shall take steps to restore it immediately.
				The supplier shall alert all users in advance of maintenance that will cause
				pressure loss or water quality change. The supplier shall follow the standards
				outlined in the
Guidelines for the Issuance of Precautionary Boil Water
				Notices
, 12/11/06 revision, available from the Department of Health,
				Division of Environmental Health/Water Programs at: 4052 Bald Cypress Way, Bin
				#C22, Tallahassee, FL 32399-1742, or

.
(c) The supplier shall alert the CHD
				twenty-four (24) hours in advance where possible, but no later than the next
				business day after any shutdown or treatment failure, or within twenty-four
				(24) hours after discovering sabotage or vandalism to the water
				system.
(d) Where continuous
				disinfection is required to remove confirmed microbioloical contamination,
				disinfection equipment shall maintain the free available chlorine residual and
				total chlorine residual between 0.2 milligrams per liter (mg/L) and 4.0 mg/L
				throughout the entire system, or the equivalent of these limits as determined
				by the Department.
1. Where continuous
				disinfection is required, the supplier shall test the chlorine residual daily
				by using a N, N-Diethyl-p-Phenylenediamine (DPD) color comparison test kit, or
				a portable spectrophotometer test kit and post the results in a log kept on
				premises. The test kit shall be functional and kept on site at all times. The
				Department shall specify tests for alternative disinfectants upon construction
				approval.
2. Where continuous
				disinfection is required for a Limited Use Community System and a chemical
				disinfectant is used, the supplier shall assure a state certified water
				treatment plant operator services the system weekly.
3. Where continuous disinfection was
				initially required prior to the effective date of this rule, the effective
				water contact volume for groundwater supplied systems shall be 15 times the PD,
				and the effective water contact volume for surface water supplied systems shall
				be 120 times the PD (in order to achieve a minimum water contact time of 15 or
				120 minutes, respectively, with the disinfectant at peak demand
				flow).
4. Where continuous
				disinfection was initially required for a groundwater supplied system on or
				after the effective date of this rule, the system must maintain the minimum
				required water contact time and free chlorine residual based on the water
				temperature exiting the contact tank according to Table 1, or designed in
				accordance with Chapters 3 and 4 of the U.S. EPA
Guidance Manual for
				Compliance with the Filtration and Disinfection Requirements for Public Water
				Systems Using Surface Water Sources
, March 1991 Edition.
5. Where disinfection equipment is installed
				on a Limited Use Public Water System but is not required, the free available
				chlorine residual and total chlorine residual shall not exceed 4.0 mg/L
				throughout the entire system.
(e) The system shall maintain a minimum water
				pressure of twenty (20) pounds per square inch throughout the water system at
				all times.
(f) The water system
				shall contain no cross-connections.
