Florida Administrative Code › 62 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 62 - Departmental › Chapter 62-6 - STANDARDS FOR ONSITE SEWAGE TREATMENT AND DISPOSAL SYSTEMS › Part IV - Performance-based Treatment Systems › Section 62-6.029 - Monitoring

Current through Reg. 50, No. 138; July 16, 2024
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 CBOD
5
, 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
				  CBOD
5
, a reading of 20 mg/l
				  CBOD
5
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.
