62-610. Reuse Of Reclaimed Water And Land Application |
1(1) Preapplication waste treatment shall result in a reclaimed water that meets secondary treatment and basic disinfection. If required by subsection 2262-610.652(5), 23F.A.C., additional treatment and disinfection shall be provided.
31(2) Individual industrial activities or users may have water quality needs which may necessitate treatment beyond the minimum requirements established in this part. The Department shall not regulate these additional treatment and disinfection requirements. These additional treatment and disinfection requirements shall be subject to negotiation between the industry and the supplier of the reclaimed water.
86(3) Except as provided in paragraph 9262-610.668(2)(d), 93F.A.C., domestic wastewater treatment or disinfection provided at the industrial facility before reuse of the reclaimed water at the industrial facility shall be subject to domestic wastewater permitting if the treatment or disinfection at the industrial site is needed to meet the minimum treatment and disinfection requirements imposed by this Part of this chapter.
147(4) If additional treatment or disinfection is provided at the industrial facility before reuse of the reclaimed water at the industrial facility, and the additional treatment or disinfection is provided only to meet water quality needs of the industry which are more stringent than the minimum requirements imposed by this part, domestic wastewater permitting shall not be needed for the additional treatment or disinfection facilities located at the industrial facility.
217(5) All requirements of Part III of this chapter, including minimum system size requirements, shall be met if reclaimed water will be used in open cooling tower applications, except as provided in paragraph 25062-610.668(2)(c) 251or (d), F.A.C.
254(6) Monitoring.
256(a) Waste treatment limitations shall be met after disinfection and before discharge to system storage or the reuse system.
275(b) If high-level disinfection is provided, the total suspended solids limitation shall be met after filtration and before application of the disinfectant.
297(c) For facilities that provide reclaimed water for use in open cooling towers, the permittee shall sample the reclaimed water for Cryptosporidium and Giardia. The following requirements shall be met:
3271. Sampling shall be conducted at one time during each two-year period. Intervals between sampling shall not exceed two years. This sampling frequency is independent of the treatment plant’s capacity. The sample results shall be submitted to the Department on or before November 28 of each even numbered year using 377Form 37862-610.300(3)(a)4., 379Pathogen Monitoring, (adopted and incorporated by reference in subparagraph 38862-610.300(3)(a)4., 389F.A.C., effective August 8, 2021, 394http://www.flrules.org/Gateway/reference.asp?No=Ref-13373396).
3972. Samples shall be taken from at a point immediately following the disinfection process.
4113. Samples shall be taken during peak flow periods between the months of August and October.
4274. If the wastewater treatment facility uses chlorination for disinfection, samples collected for analysis of Giardia and Cryptosporidium shall be dechlorinated.
4485. A grab sample for TSS shall be taken such that it is representative of the water leaving the filters at the treatment facility during the period when pathogen samples are taken. In addition, the permittee shall record the lowest total residual chlorine observed during the period when pathogen samples are collected.
5006. EPA Method 1623504.1, (adopted and incorporated by reference in subsection 51262-610.100(7), 513F.A.C., effective August 8, 2021, 518http://www.flrules.org/Gateway/reference.asp?No=Ref-133825201521), 522or other approved methods 526in accordance with Rule 53062-160.330, 531F.A.C., 532for reclaimed water or nonpotable waters, adjusted appropriately to accommodate the detection limit requirements, shall be used. Methods previously allowed for EPA’s ICR shall not be used. The full requirements of the approved method, including quality assurance and quality control, are to be met. Quality assurance and sampling requirements in Chapter 62-160, F.A.C., shall apply.
587Two concentrations of Giardia and Cryptosporidium shall be recorded on Part III of 600Form 60162-610.300(3)(a)4., 602Pathogen Monitoring, (adopted and incorporated by reference in subparagraph 61162-610.300(3)(a)4., 612F.A.C., effective August 8, 2021, 617http://www.flrules.org/Gateway/reference.asp?No=Ref-13373619).
620a. Total cysts and oocysts shall be enumerated using EPA Method 1623632.1, (adopted and incorporated by reference in subsection 64062-610.100(7), 641F.A.C., effective August 8, 2021, 646http://www.flrules.org/Gateway/reference.asp?No=Ref-13382648), 649or other approved methods 653in accordance with Rule 65762-160.330, 658F.A.C.
659b. Potentially viable cysts and oocysts shall be enumerated using the DAPI staining technique contained in EPA Method 1623678.1, (adopted and incorporated by reference in subsection 68662-610.100(7), 687F.A.C., effective August 8, 2021, 692http://www.flrules.org/Gateway/reference.asp?No=Ref-13382694), 695or similar enumeration techniques included in other approved methods 704in accordance with Rule 70862-160.330, 709F.A.C710. Cysts and oocysts that are stained DAPI positive or show internal structure by D.I.C. shall be considered as being potentially viable. If the laboratory reports separate values for DAPI positive and for cysts or oocysts having internal structure, the larger of the two concentrations will be reported as being potentially viable.
7627. 763If the number of potentially viable cysts of Giardia reported exceeds 5 per 100 liters or oocysts of Cryptosporidium reported exceeds 22 per 100 liters, a subsequent sample shall be taken and analyzed using EPA Method 1623800.1, (adopted and incorporated by reference in subsection 80862-610.100(7), 809F.A.C., effective August 8, 2021, 814http://www.flrules.org/Gateway/reference.asp?No=Ref816-81713382818), 819or other approved methods 823in accordance with Rule 82762-160.330, 828F.A.C829.
