Table 1 Notes:
Above values are based on a water pH of no greater than 9.0 and a baffling factor of 0.1 (no baffling). Water temperature, pH and free chlorine residuals are based on the water exiting the contact tank.
1For initial design of disinfection systems, use the coldest anticipated water temperature exiting the contact tank.
a. Therefore, the effective water contact volume for groundwater supplied systems shall be a minimum of either fifteen (15), or thirty (30) or forty-five (45) times the PD (to achieve a minimum water contact time of either 15, or 30 or 45 minutes with the disinfectant at peak demand flow, based on Table 1 values).
b. through e. No change.
(c) through (d) No change.
(e) Beginning on the effective date of this rule chapter, systems supplied by surface water or cisterns, and systems supplied by groundwater where continuous disinfection is required but is not designed according to Table 1 above, must be designed by a professional engineer and must include treatment designed according to Chapters 3 and 4 of the Guidance Manual for Compliance with the Filtration and Disinfection Requirements for Public Water Systems Using Surface Water Sources, March 1991 Edition, available from the U.S. Environmental Protection Agency (EPA) at: Office of Groundwater and Drinking Water (4601), Ariel Rios Building, 1200 Pennsylvania Avenue N. W., Washington, DC, 20460-0003, or www.epa.gov/safewater/mdbp/implement.html. All such plans must be reviewed and approved by the Department’s Bureau of Water Programs.
(5) No change.
(6) All equipment shall be installed and operated in accordance with manufacturer's instructions and specifications. Only food or water-grade chemicals, equipment and materials shall be used. These items shall meet the standards of the U.S. Food and Drug Administration under Title 21 of the Code of Federal Regulations (CFR) Parts 170-199, April 1, 2007; and Pertinent Federal Registers; or meet the National Sanitation Foundation/American National Standards Institute, NSF/ANSI Standard 60-2005, entitled Drinking Water Treatment Chemicals – Health Effects, and NSF/ANSI Standard 61-2007, entitled Drinking Water System Components – Health Effects, available from NSF International at P. O. Box 130140, Ann Arbor, Michigan, 48113-0140; or meet the standards of another ANSI accredited testing and certification organization.
(7) through (10) No change.
64E-8.004 Annual Operating Permits, Existing Systems, Systems Constructed On or After 1/1/93, Annual Inspections and Registrations
(1) through (4) No change.
(5) Suppliers of Limited Use Commercial Public Water Systems that do not make tap water available for public consumption are eligible for a Registration exemption if the system meets the water quality standards of subsection 64E-8.006(2), F.A.C., and does not require continuous disinfection to remove microbiological contamination. Registered systems are exempt from obtaining annual operating permits. If corrective treatment equipment is required to correct a chemical MCL or HAL violation, the supplier shall not be eligible for a Registration exemption and shall be required to obtain an annual operating permit, unless the treatment equipment is actively managed and maintained by the Department of Environmental Protection’s Water Supply Restoration Program.
(a) through (d) No change.
(e) In order to retain their potable water status as is required by the Federal Occupational Health and Safety Administration under 29 CFR 1910.141, July 1, 2007, and the Florida Plumbing Code, 2004, suppliers of Registered systems as described within this section must perform annual testing for bacteria in the form of one (1) satisfactory microbiological sample per year. Such analyses shall be performed no more than twelve (12) months apart and the results shall be provided to the Department no later than fifteen (15) days after the time period in which the sample was required.
