Fla. Admin. Code Ann. R. 62-610.568 - Monitoring and Operating Protocol
(1) Only acceptable quality reclaimed water
shall be discharged to reuse systems regulated under Part V of this
chapter.
(2) Reclaimed water
limitations shall be met before injection to ground water or discharge to
surface waters. For projects requiring high-level disinfection, the TSS
limitation shall be achieved before disinfection, regardless of the actual
reclaimed water compliance monitoring location.
(3) The treatment facility shall include
continuous on-line monitoring for turbidity before application of the
disinfectant. Continuous monitoring for total residual chlorine or for residual
concentrations of other disinfectants, if used, shall be provided at the
compliance monitoring point. Instruments for continuous on-line monitoring
shall be equipped with an automated data logging or recording device.
Continuous online monitoring instruments shall be calibrated according to the
requirements of Chapters 62-160 and 62-600, F.A.C. Continuous online monitoring
instruments shall be maintained according to the manufacturer's operation and
maintenance instructions.
(4)
Treatment facilities designed to meet the full treatment and disinfection
requirements shall have the reclaimed water sampled and analyzed for TOC and
TOX daily, seven days per week.
(5)
Treatment facilities that are required to meet the drinking water standards
shall sample the reclaimed water for parameters regulated as drinking water
standards as follows:
(a) If the treatment
facility is required to meet the bacteriological requirements of the drinking
water standards, total coliforms and total suspended solids shall be analyzed
daily.
(b) Parameters listed as
primary drinking water standards that are imposed as reclaimed water limits
shall be analyzed monthly. After the first year, the Department shall reduce
the monitoring frequency if the applicant provides an affirmative demonstration
that reclaimed water limits and ground water standards will be met and that
public health will be protected. In no case shall the frequency of this
monitoring be reduced below quarterly.
(c) Parameters listed as secondary drinking
water standards that are imposed as reclaimed water limits shall be analyzed
quarterly. After the first year, the Department shall reduce the monitoring
frequency if the applicant provides an affirmative demonstration that reclaimed
water limits and ground water standards will be met and that public health will
be protected. In no case shall the frequency of this monitoring be reduced
below annually. The pH of the reclaimed water shall be analyzed
daily.
(d) Except for total
coliforms and pH, twenty-four hour composite samples shall be used to analyze
the reclaimed water for parameters listed as primary or secondary drinking
water standards.
(6)
Other reclaimed water monitoring shall meet the requirements of Chapter 62-600,
F.A.C.
(7) In accordance with Rule
62-610.320, F.A.C., the
permittee shall develop, and the Department shall approve, an operating
protocol designed to ensure that the reclaimed water limitations will be met
before the reclaimed water is released to the reuse system. For treatment
facilities required to provide full treatment and disinfection, the operating
protocol shall include monitoring and control of key treatment processes for
removal of organic compounds required by subsection
62-610.563(3),
F.A.C., and shall incorporate the fail safe "lock-out" provisions of subsection
62-610.567(2),
F.A.C. In the engineering report, the applicant shall describe and justify the
operational controls on the key treatment processes for removal of organic
compounds. Reclaimed water produced at the treatment facility that fails to
meet the criteria established in the operating protocol shall not be released
to the system storage or reuse system. Such substandard reclaimed water (reject
water) shall be either stored for subsequent additional treatment or shall be
discharged to another permitted reuse system requiring lower levels of
preapplication treatment or to a permitted effluent disposal system. The
operating protocol shall be reviewed and updated by the permittee as required
by Rule 62-610.320, F.A.C. The permittee
shall submit the current operating protocol to the Department for review with
any application to renew or modify the permit.
(8) Ground water monitoring requirements
shall be as specified in Rule
62-610.412, F.A.C. A ground
water monitoring plan meeting the requirements of Chapters 62-520, 62-600, and
62-610, F.A.C., is required. Submittal and approval of ground water monitoring
plans shall be in accordance with Rule
62-520.600, F.A.C. Department
approval of the ground water monitoring plan is a prerequisite for issuance of
the initial permit.
(9) The surface
water or ground water receiving the reclaimed water shall be sampled quarterly
for the parameters for which primary or secondary drinking water standards have
been established. After the first year of operation, the Department shall
reduce the sampling frequency if the applicant provides an affirmative
demonstration that water quality standards will be met in the receiving surface
water or ground water and that public health will be protected. For ground
water recharge projects, reductions in monitoring shall be considered only
after the injected reclaimed water reaches a monitoring well. The complete list
of all regulated parameters shall be sampled and analyzed for at least
annually.
(10) Except as noted in
subsection 62-610.568(11),
F.A.C., the permittee shall sample the reclaimed water for Cryptosporidium and
Giardia. The following requirements shall be met:
(a) Sampling shall be conducted quarterly.
Intervals between sampling shall not exceed three months. The sample results
shall be submitted to the Department on or before February 28, May 28, August
28, and November 28 of each year using Form

(b) Samples shall be taken at a point
immediately following the final treatment or disinfection process within the
treatment facility.
(c) Sampling
for Cryptosporidium and Giardia shall be required only for the following types
of projects:
1. Discharge to Class I surface
waters, as described in Rule
62-610.554, F.A.C.
2. Discharge to waters contiguous to or
tributary to Class I surface waters, as described in subsection

4. Discharges to surface waters that are
directly connected to ground water, which serve as ground water recharge, as
described in subsection
62-610.555(4),
F.A.C.
(d) Samples shall
be taken during peak flow periods between the months of August and
October.
(e) If the wastewater
treatment facility uses chlorination for disinfection, samples collected for
analysis of Giardia and Cryptosporidium shall be dechlorinated.
(f) 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.
