Current through Reg. 50, No. 138; July 16, 2024
(1) Wastewater
				  treatment facilities shall monitor the flow, the influent for
				  CBOD5 and TSS, and the reclaimed water or effluent for
				  all reclaimed water or effluent parameters as required by the permit. The
				  minimum schedule for sampling and testing parameters to be monitored at a
				  wastewater treatment plant is specified in Figure 1 below.

1Hourly measurements during the
					 period of required operator attendance may be substituted for continuous
					 measurement.
2Total chlorine residual
					 measured for disinfection effectiveness (after chlorine contact). Hourly
					 measurements during the period for required operator attendance may be
					 substituted for continuous measurement except for systems permitted under Parts
					 III and V of Chapter 62-610, F.A.C. Continuous measurement shall be provided
					 for all systems permitted under Parts III and V of Chapter 62-610, F.A.C.,
					 regardless of permitted capacity.
3Reuse and land application
					 facilities (which include rapid-rate, slow-rate, absorption fields and other
					 systems pursuant to Chapter 62-610, F.A.C.) less than 100, 000 gpd, may sample
					 monthly. (This reduction does not apply to injection wells pursuant to Chapter
					 62-528, F.A.C., and reuse systems requiring high-level disinfection.)
4For reuse systems requiring
					 high-level disinfection, samples shall be obtained and reported daily, 7 days
					 per week for systems of 0.5 mgd and greater, 4 days per week for systems of at
					 least 50, 000 gpd but less than 0.5 mgd, and 3 days per week for systems less
					 than 50, 000 gpd; or daily during the period required for operator attendance,
					 whichever is less. At permit renewal, reduction to 4 days per week for systems
					 of 0.5 mgd and greater or to 3 days per week for systems of at least 50, 000
					 gpd but less than 0.5 mgd may be requested if no violations for these
					 parameters have occurred in the last 12 months. For systems requiring
					 high-level disinfection, the reduction allowed by note 3 does not apply.
5Total chlorine residual
					 measured for dechlorination effectiveness.
6Not applicable to reuse systems
					 discharging to Class I waters or waters contiguous to or tributary to Class I
					 waters or to reuse systems injecting into Class F-I, G-I, or G-II ground
					 waters.
7Applicable to reuse systems
					 discharging to Class I waters or waters contiguous to or tributary to Class I
					 waters or to reuse systems injecting into Class F-I, G-I, or G-II ground
					 waters. These systems shall monitor 7 days per week for total coliform,
					 regardless of permitted capacity, as specified in Parts III and V of Chapter
					 62-610, F.A.C.
8The daily frequency shall be 2,
					 3, or 5 days per week consistent with the required operator attendance
					 specified in paragraph
					  62-699.310(2)(a),
					 F.A.C.
9Applicable to surface water
					 discharges to Class I and Class III freshwater in accordance with Rule
					  62-302.530, F.A.C.
10Applicable to surface water
					 discharges to predominately marine Class III waters in accordance with Rule
					  62-302.530,
					 F.A.C.
(2) Wastewater
				  treatment facilities with a permitted capacity of 100, 000 gallons per day or
				  greater that discharge to ground water via reuse and land application systems
				  shall monitor the reclaimed water or effluent for the primary and secondary
				  drinking water standards contained in Chapter 62-550, F.A.C., and the Revised
				  Total Coliform Rule contained in Rule
				   62-550.830, F.A.C., (except for
				  asbestos, color, odor, and residual disinfectants) annually.
(3) Sample types.
(a) Grab samples shall be used to test pH,
				  chlorine residual, dissolved oxygen and other dissolved gases, microbiological
				  parameters, cyanide, oil and grease, dissolved constituents in field-filtered
				  samples (ortho-phosphorus, metals, etc.), specific conductance, un-ionized
				  ammonia, volatile organic compounds, total recoverable petroleum hydrocarbons,
				  and temperature.
(b) Grab samples
				  shall be used to test CBOD5,  TSS, and nutrients at
				  facilities with a permitted capacity less than 100, 000 gallons per day. Except
				  as provided in paragraphs
				   62-600.660(3)(c) and
				  (d), F.A.C., all other samples for CBOD5,
				  TSS, and nutrients shall be flow proportioned, composite samples and
				  compositing periods shall be 24, 16, or 8 hours based on the facility's
				  staffing requirement. In no case shall the compositing period be less than 8
				  hours.
(c) Grab samples shall be
				  used to test for TSS where a facility is required to meet the 5.0 mg/L TSS
				  limitation associated with high-level disinfection for a reuse system permitted
				  under Chapter 62-610, F.A.C.
(d)
				  Except for the parameters listed in paragraph
				   62-600.660(3)(a),
				  F.A.C., 24 hour flow proportioned, composite samples shall be used to analyze
				  reclaimed water or effluent for the primary and secondary drinking water
				  standards.
(e) Grab samples shall
				  be collected during periods of minimal treatment plant pollutant removal
				  efficiencies or maximum organic loading in the reclaimed water or effluent. The
				  actual time and flow conditions during which such samples are taken shall be
				  recorded.
