Fla. Admin. Code Ann. R. 62-6.029 - Monitoring
Monitoring requirements - All performance-based treatment systems shall be monitored in compliance with the requirements in this section. If soil is considered part of the treatment system in any performance-based standard, monitoring points in the effluent plume within the boundaries of the property must be in compliance with the minimum criteria for total nitrogen, total phosphorous and fecal coliform.
(1) Advanced wastewater treatment systems.
(a) A maintenance report shall be kept by the
performance system maintenance entity. A copy of all maintenance reports shall
be provided to the Department on monthly intervals, to begin one month after
system operation has started. After the first six reports are provided to the
Department, reports shall be provided once every three months. All reports must
be legible. The report shall include the following information:
1. Address of performance-based treatment
system.
2. Date and time of
inspection.
3. Sample collection
time and date, and person who collected sample.
4. Results of all sampling.
5. Volume of effluent treated, to include
total monthly and daily average.
6.
Maintenance performed.
7. Problems
noted with performance-based treatment system and actions taken or proposed to
overcome them.
8. During the first
six months of system operation, or after the system has failed, systems shall
be monitored a minimum of once every two weeks. Monitoring shall include
sampling for CBOD5, TSS, TN, TP and fecal
coliform. Monitoring shall occur at the time the system is expected to be at
capacity, or as close to capacity as possible. Re-sampling within 48 hours of
receipt of laboratory results shall be allowed on all samples that exceed
design parameters in order to evaluate the validity of the original sample
results. If the re-sample is in compliance with the appropriate
performance-based standard, the original result shall be disregarded.
Laboratories must be approved by the Department for all analyses performed. All
results shall be certified by the laboratory.
a. If any two consecutive samples exceed
design treatment standards by more than 100%, the system design and operation
shall be inspected by the design engineer for conformance with permitting
requirements, and shall be adjusted to bring the effluent quality into
compliance with permitting requirements. Monitoring shall be increased to once
per week, or more if the design engineer specifies such, until such time the
violation is corrected. When two consecutive samples are within 100% of the
design parameters, monitoring shall be reduced to once every two weeks. For
example, if the design parameter is 10 mg/l
CBOD5, a reading of 20 mg/l
CBOD5 exceeds the standard by
100%.
b. After a six month period
of compliance with all applicable performance standards, sampling shall be
performed quarterly.
c. When an
applicant installs a system designed to meet advanced wastewater treatment
standards, the monitoring frequency shall be reduced by 50% if only one of the
following three location and installation requirements is used and the other
two remain at the standards required of prescriptive systems. The three
requirements are:
(I) Setbacks required in
paragraphs 62-6.028(1)(a)
-(c), F.A.C.
(II) Seasonal high
water table subparagraph
62-6.028(1)(c)
4., F.A.C.
(III) Authorized lot
flow subsection 62-6.028(2),
F.A.C.
(b) When four consecutive once every two week
samples from a system are at or below the applicable standard, sampling
frequency shall be reduced to quarterly.
(c) When eight consecutive quarterly samples
from a system are below the applicable standard, sampling frequency shall be
reduced to once every six months.
(d) All reports of operating permit
violations shall be reported to the Department within five working
days.
(e) If the system cannot be
brought into compliance with design parameters, the contingency plan must be
enforced.
(f) All failures of the
performance-based treatment system shall be reported to the Department by the
maintenance entity within one working day from discovery of failure. The
testing laboratory shall mail copies of all results to the
Department.
(g) Testing performed
during periods of system non-use that exceed one week, shall not qualify as
legitimate samples for purposes of compliance with any provisions of this
rule.
(2) Secondary
treatment systems and advanced secondary treatment systems.
(a) A maintenance report shall be kept by the
performance system maintenance entity. A copy of all maintenance reports shall
be provided to the Department on quarterly intervals. All reports must be
legible. The report shall include the items required in subparagraphs
62-6.029(1)(a)
1., 2., 5., 6. and 7., F.A.C., in addition to the following information:
1. Ponding depth observed through drainfield
observation ports or, when the drainfield design prevents direct measurement of
ponding depth, CBOD5 and TSS results for samples
collected at a point prior to the discharge to the drainfield.
2. If system performance is necessitated by
setback reductions or lot flow allowances:
a.
Sampling results for Fecal Coliform from Secondary Treatment Systems.
b. Sampling results for Nitrogen, Phosphorous
and Fecal Coliform from Advanced Secondary Treatment Systems.
c. Collection time and date of all
samples.
d. Name of the person who
collected samples.
(b) All reports of operating permit
violations shall be reported to the Department within five working
days.
(c) If the system cannot be
brought into compliance with design parameters, the contingency plan must be
implemented by the system owner.
(d) All failures of the performance-based
treatment system shall be reported to the Department by the maintenance entity
within one working day from discovery of failure. The testing laboratory shall
mail copies of all results to the Department.
(3) Florida Keys nutrient reduction treatment
systems shall be monitored and sampled in accordance with Part II of this
chapter.
(4) All systems with
drainfields designed under subsections
62-6.028(3)
-(5), F.A.C., shall be monitored via placing a minimum of two observation ports
in the drainfield. Monitoring will consist of recording depth of effluent
ponding in the drainfield in at least two places on a quarterly
basis.
(5) If soil is considered
part of the treatment system in any performance-based standard, two monitoring
points in the effluent plume within the boundaries of the property must be in
compliance with the performance level specified by the design
engineer.
(6) Any performance-based
treatment system that is out of compliance with the terms of the operating
permit shall be re-engineered by an engineer registered in the State of
Florida. The system shall be brought into compliance with treatment standards
required at the time of system permitting.
(7) Innovative systems shall be monitored in
accordance with the design engineer's protocol submitted with the application
as approved by the Department. All monitoring and sampling shall be performed
at the expense of the applicant. At a minimum, the monitoring protocol shall:
(a) Determine if baseline standards are being
met.
(b) Address the monitoring for
any contaminant being reduced.
(c)
Address the monitoring of any site condition being
modified.
(8) The
following shall be considered as violations of the performance-based treatment
system operating permit:
(a) The failure to
maintain equipment in a condition which will enable the intended
function.
(b) The submission, by
the owner, manager or maintenance entity of a performance-based treatment
system, or agent or employee thereof, of misleading, false, or inaccurate
information or operational reports to the Department, either knowingly or
through neglect.
(c) The submission
of fraudulent data produced with an intention to deceive including the
following:
1. Apparent measurement results
for which no measurement or test results were actually made as determined by
the absence of the supporting records which are usually made.
2. Measurements or test results obtained by
deliberately and knowingly making measurements or collecting samples at places
and times other than as specified in this chapter.
3. Test results obtained through use of
unapproved and erroneous sampling, preservation, storage, or analysis
procedures.
4. Computational
errors, misunderstandings of required procedures and other common errors are
excluded.
