PURPOSE AND EFFECT: The Department is adopting the national Stage 2 Disinfectants and Disinfection Byproducts Rule (D/DBPR) with related State clarifications and additions, and the Department is updating the State’s public water system recordkeeping and Stage 1 D/DBPR requirements to incorporate changes that were made to the record maintenance and Stage 1 D/DBPR requirements in the national primary drinking water regulations and that were promulgated with the Stage 2 D/DBPR. Also, the Department is updating the State’s listing of analytical methods for primary or secondary contaminants and the State’s consumer confidence report (CCR) requirements so they are consistent with current national primary or secondary drinking water regulations.
SUMMARY: Rule 62-550.200, F.A.C., is being amended to incorporate new or revised definitions from the Stage 2 D/DBPR and to make minor technical corrections. Rule 62-550.310, F.A.C., is being amended to expand the applicability of the Stage 1 D/DBPR maximum residual disinfectant levels (MRDLs) for chlorine and chloramines in accordance with the Stage 2 D/DBPR; to clarify that the Stage 1 D/DBPR maximum contaminant levels (MCLs) for total trihalomethanes (TTHM) and haloacetic acids (five) (HAA5) apply until the date specified for compliance with the Stage 2 D/DBPR MCLs for TTHM and HAA5; to specify the water systems to which the Stage 2 D/DBPR TTHM and HAA5 MCLs apply; and to specify the effective dates for the Stage 2 D/DBPR TTHM and HAA5 MCLs. Rule 62-550.500, F.A.C., is being amended to clarify that the monitoring and compliance measurement requirements under the Stage 2 D/DBPR take precedence over the general monitoring and compliance measurement requirements in Rule 62-550.500, F.A.C., and to indicate that monitoring frequencies under the Stage 2 D/DBPR are specified in new Rule 62-550.822, F.A.C. Rule 62-550.514, F.A.C., is being amended to expand the applicability of the Stage 1 D/DBPR chlorine and chloramine monitoring requirements in accordance with the Stage 2 D/DBPR; to clarify that community or non-transient non-community water systems that add a chemical disinfectant to the water must monitor for TTHM and HAA5 under the Stage 1 D/DBPR until the date specified for compliance with the Stage 2 D/DBPR MCLs for TTHM and HAA5; and to specify that community or non-transient non-community water systems that add, or deliver water that has been treated with, a primary or residual disinfectant other than ultraviolet (UV) light must monitor for TTHM and HAA5 under the Stage 2 D/DBPR starting with the date specified for compliance with the Stage 2 D/DBPR MCLs for TTHM and HAA5. Rule 62-550.540, F.A.C., is being amended to clarify residual disinfectant monitoring requirements under the D/DBPRs for consecutive systems; to clarify disinfection byproduct (DBP) monitoring requirements under the D/DBPRs for consecutive systems; and to make minor technical changes. Rule 62-550.550, F.A.C., is being amended to specify who may perform, and appropriate procedures or methods for performing, residual disinfectant measurements to demonstrate that Stage 2 D/DBPR TTHM and HAA5 samples were taken under normal operating conditions. Rule 62-550.550, F.A.C., also is being amended to reference all analytical methods currently listed in the national primary or secondary drinking water regulations; to delete the sentence allowing use of alternative analytical techniques with written permission; and to clarify that the Department approves the use of the Industrial Test Systems free chlorine test strip for the determination of free chlorine. Rule 62-550.720, F.A.C., is being amended to incorporate revisions that the U.S. Environmental Protection Agency (USEPA) made to the record maintenance requirements in the national primary drinking water regulations and published with the Stage 2 D/DBPR. Rule 62-550.730, F.A.C., is being amended to reference the Stage 2 D/DBPR reporting format for DBPs (TTHM and HAA5) in new Rule 62-550.822, F.A.C., and to make minor technical corrections. Rule 62-550.821, F.A.C., is being revised to make a minor technical correction and to incorporate revisions that the USEPA made to the Stage 1 D/DBPR and published with the Stage 2 D/DBPR. The USEPA revisions to the Stage 1 D/DBPR include the following: updating of analytical requirements under the Stage 1 D/DBPR; addition of source water total organic carbon monitoring requirements for subpart H systems that are not using conventional filtration treatment and that wish to qualify for reduced TTHM and HAA5 monitoring under the Stage 1 D/DBPR; and revision of the criteria to qualify for reduced bromate monitoring under the Stage 1 D/DBPR. Rule 62-550.822, F.A.C., is being added to incorporate the Stage 2 D/DBPR requirements with State clarifications and additions. The Stage 2 D/DBPR requirements include the following: initial distribution system evaluation requirements included under 40 C.F.R. § 141 subpart U; and the Stage 2 D/DBPR compliance monitoring and other requirements included under 40 C.F.R. § 141 subpart V. Rule 62-550.824, F.A.C., is being amended to reference the current edition of subpart O–“CCRs”–and Appendix A to subpart O in 40 C.F.R. § 141. Table 3 is being amended to incorporate the Stage 2 D/DBPR MCLs for TTHM and HAA5. Tables 7 and 8 are being amended to incorporate Stage 2 D/DBPR monitoring requirements and to make minor technical corrections. There are a number of Department rules that reference these rules being amended. Rules 62-555.320, 62-555.360, 62-555.401, and 62-560.410, F.A.C., reference Rule 62-550.200, F.A.C., but the amendment to Rule 62-550.200, F.A.C., will have no effect on those rules. Rules 62-520.420, 62-528.425, 62-560.610, and 62-560.620, F.A.C. refer to the disinfection byproduct maximum contaminant levels that are being revised under Rule 62-550.310, F.A.C. Also, Rules 62-555.325, 62-560.410, 62-560.510, 62-560.520, 62-560.545, and 62-560.610, F.A.C., reference Rule 62-550.310, F.A.C., but the amendment to Rule 62-550.310, F.A.C. will have no effect on those rules. Rules 62-555.320 and 62-560.546, F.A.C., reference Rule 62-550.500, F.A.C., but the amendment to Rule 62-550.500, F.A.C., will have no effect on those rules. Rules 62-555.315, 62-555.325, 62-555.340, 62-555.350, and 62-555.530, F.A.C., refer to the list of referenced analytical methods that is being amended under Rule 62-550.550, F.A.C. Also, Rule 62-699.311, F.A.C., references Rule 62-550.550, F.A.C., but the amendment to Rule 62-550.550, F.A.C., will have no effect on that rule. Rule 62-555.350, F.A.C., references Rule 62-550.720, but the amendment to Rule 62-550.720, F.A.C., will have no effect on that rule. Rules 62-555.350, 62-560.410, and 62-560.530, F.A.C., reference Rule 62-550.730, F.A.C., but the amendment to Rule 62-550.730, F.A.C., will have no effect on those rules. Rule 62-560.410, F.A.C., references Rule 62-550.821, F.A.C., but the amendment to Rule 62-550.821, F.A.C., will have no effect on that rule. Rule 62-560.410, F.A.C., references Rule 62-550.824, F.A.C., but the amendment to Rule 62-550.824 will have no effect on that rule. Many Department rules reference the primary or secondary drinking water standards or just the water quality standards contained in Chapter 62-550. However, these rule amendments do not change any numerical standard. Therefore the following rules are not affected by this rulemaking: Rules 62-312.825, 62-330.100, 62-330.200, 62-341.486, 62-346.051, 62-346.301, 62-521.400, 62-524.200, 62-552.650, 62-600.420, 62-600.510, 62-301.300, 62-606.400, 62-610.300, 62-610.525, 62-610.865, 62-761.200, 62-762.201,62-770.200, 62-780.200, 62-782.200, and 62-785.200, F.A.C.
SUMMARY OF STATEMENT OF ESTIMATED REGULATORY COSTS: The Department has determined that these rule amendments will have an impact on small businesses and has prepared a SERC. Community water systems (CWSs) and non-transient non-community water systems (NTNCWSs) will incur both a one-time cost and a recurring annual cost to comply with the Stage 2 D/DBPR. For CWSs serving less than 10,000 persons, many of which probably are a small business or an ancillary part of a small business, the estimated average one-time cost is approximately $1,360 per CWS and the estimated average annual cost is approximately $1,090 per CWS. The estimated average one-time and average annual costs for NTNCWSs serving less than 10,000 persons, many of which probably are an ancillary part of a small business, are approximately $330 and $230, respectively. The estimated total one-time and annual costs for all CWSs in Florida to comply with the Stage 2 D/DBPR are $4.53 million and $8.62 million, respectively; and the estimated total one-time and annual costs for all NTNCWSs in Florida to comply with the Stage 2 D/DBPR are $318,000 and $229,000, respectively. Assuming CWSs pass all costs on to their customers, customers of CWSs in Florida will incur an average one-time cost of $0.79 per customer and an average annual cost of $1.49 per customer as a result of the Stage 2 D/DBPR. A copy of the SERC is available from Virginia Harmon, Department of Environmental Protection, 2600 Blair Stone Road, M.S. 3520, Tallahassee, FL 32399-2400, [phone], [e-mail].
Any person who wishes to provide information regarding a statement of estimated regulatory costs, or provide a proposal for a lower cost regulatory alternative must do so in writing within 21 days of this notice.

(34) “DUAL SAMPLE SET” means a set of two samples collected at the same time and same location, with one sample analyzed for TTHM and the other sample analyzed for HAA5. Dual sample sets are collected for the purpose of conducting an IDSE under subpart U of 40 C.F.R. § 141 as incorporated into Rule 62-550.822, F.A.C., and for the purpose of determining compliance with the TTHM and HAA5 MCLs under subpart V of 40 C.F.R. §141 as incorporated into Rule 62-550.822, F.A.C.

(33) through (38) renumbered (35) through (40) No change.

(41) “FINISHED WATER” means water that is introduced into the distribution system of a public water system and is intended for distribution and consumption without further treatment, except treatment as necessary to maintain water quality in the distribution system (e.g., booster disinfection or addition of corrosion control chemicals).

(39) through (40) renumbered (42) through (43) No change.

(44)(41) “GAC10” means granular activated carbon filter beds with an empty-bed contact time of 10 minutes based on average daily flow and a carbon reactivation frequency of every 180 days, except that the reactivation frequency for GAC10 used as a best available technology for compliance with Stage 2 MCLs under paragraph 62-550.310(3)(d), F.A.C., shall be 120 days.

NOTE 1: Systems susceptible to asbestos contamination due solely to corrosion of asbestos-cement pipe shall sample at a tap served by asbestos-cement pipe and under conditions where asbestos contamination is most likely to occur. Systems susceptible to asbestos contamination due solely to source water shall monitor at every entry point to the distribution system during normal operating conditions. Systems susceptible to asbestos contamination due to both source water and corrosion of asbestos-cement pipe shall sample at a tap served by asbestos-cement pipe and under conditions where asbestos contamination is most likely to occur.

NOTE 2: Systems shall measure the residual disinfectant level at the same locations in the distribution system where, and at the same time when, total coliforms are sampled.

NOTE 3: Systems shall take routine daily samples at the entrance to the distribution system. Systems shall take additional three-sample sets in the distribution system at the following locations:

(a) If chloramines are used to maintain a disinfectant residual in the distribution system, or if chlorine is used to maintain a disinfectant residual in the distribution system and there are no disinfectant addition disinfection points after the entrance to the distribution system (i.e., no booster chlorination), the system shall take three samples as close to the first customer as possible at intervals of at least six hours.

(b) If chlorine is used to maintain a disinfectant residual in the distribution system and there are one or more disinfectant addition points after the entrance to the distribution system (i.e., booster chlorination), the system shall take one sample at each of the following locations: as close to the first customer as possible, in a location representative of average residence time, and as close to the end of the distribution system as possible.

NOTE 4: Systems taking one sample shall take the sample at a location reflecting maximum residence time in the distribution system. Systems taking more than one sample shall take at least 25% of the samples at locations representing maximum residence time of the water in the distribution system and shall take the remaining samples at locations representing at least average residence time in the distribution system and representing the entire distribution system, taking into account number of persons served, different sources of water, and different treatment methods.

NOTE 5: Systems shall take routine daily samples at the entrance to the distribution system. Systems shall take routine monthly or additional three-set samples in the distribution system; each three-set sample shall consist of one sample at each of the following locations: a location as close to the first customer as possible, a location representative of average residence time, and a location reflecting maximum residence time in the distribution system.

NOTE 6: For initial base point monitoring, systems shall take four consecutive quarterly samples during the first three-year compliance period. If a system does not detect any VOC, it shall take one sample annually beginning with the next three-year compliance period.

NOTE 7: During the first quarter of initial base point monitoring, GW systems shall take a minimum of one sample that is representative of each well. Under all other circumstances, systems shall sample at every entry point to the distribution system during normal operating conditions.

NOTE 8: The minimum number of samples shall be as set forth in subsection Rule 62-550.518(2), F.A.C.

NOTE 9: Systems shall conduct repeat monitoring in accordance with subsection Rule 62-550.518(7), F.A.C., and systems that routinely collect fewer than five samples per month shall collect at least five samples during the next month the system provides water to the public.

NOTE 10: The Department shall waive the final two quarters of initial monitoring for a sampling point if the results of the samples from the previous two quarters are below the regulatory detection limit. Additionally, under the conditions described in paragraph Rule 62-550.519(1)(c), F.A.C., historical data may be used to satisfy initial monitoring requirements. Systems shall take one sample quarterly if an MCL is exceeded.

NOTE 11: Quarterly monitoring for gross beta shall be based on the analysis of monthly samples or the analysis of a composite of three monthly samples. For iodine-131, a composite of five consecutive daily samples shall be analyzed once each quarter. Annual monitoring for tritium and strontium-90 shall be conducted by means of the analysis of a composite of four consecutive quarterly samples or analysis of four quarterly samples.
