Florida Administrative Code › 40 - WATER MANAGEMENT DISTRICTS › 40E - South Florida Water Management District › Chapter 40E-63 - EVERGLADES PROGRAM › Part IV - EVERGLADES PROGRAM: C-139 BASIN › Section 40E-63.464 - Limiting Conditions for the Permit Basin Discharge Monitoring Program

Current through Reg. 50, No. 138; July 16, 2024
For those applicants proposing to implement the Permit
					 Basin Discharge Monitoring Program, the District-approved monitoring plan will
					 be incorporated into a modified General Permit and the following limiting
					 conditions shall be met in addition to the conditions indicated in Rule
					  40E-63.444, F.A.C. These
					 limiting conditions will be attached to the General Permit.
(1) The discharge (quantity and quality)
				  monitoring plan shall provide reasonable assurance that the annual water
				  discharge and total phosphorus load are accurately documented.
(2) The approved discharge monitoring plan
				  shall be incorporated by reference and made part of this permit;
(3) The equipment shall be installed and the
				  monitoring shall start no later than 30 days after the permit issuance date.
				  Within 60 days after the permit issuance date, the permittee shall contact the
				  District to verify that installation of the monitoring equipment is complete
				  and to schedule an inspection;
(4)
				  The permittee shall implement the discharge monitoring plan in accordance with
				  the permit and shall submit to the District any proposed modification of the
				  plan by submitting an application to modify the permit for review and approval
				  prior to implementation.
(5) The
				  location of sample collection shall be such that water sampled is
				  representative of all water from the monitored area that discharges
				  off-site.
(6) All water quality
				  sample collection, preservation, handling, transport, and chain-of-custody
				  documentation shall be conducted in accordance with an approved Comprehensive
				  Quality Assurance Plan as specified in the approved discharge monitoring plan.
				  All laboratory analyses shall be conducted by a laboratory with proper
				  certification for the specified parameter (e.g. phosphorus);
(7) In the event that water quality automatic
				  sampling equipment becomes inoperable for any reason, grab samples shall be
				  temporarily taken on a daily basis during flow events and composited for a
				  maximum of 14 days for total phosphorus analysis. Reasonable effort must be
				  made to render the automatic sampling equipment operable within 14
				  days;
(8) Monitoring conditions may
				  be reduced or adjusted upon submission of data and/or studies that provide the
				  basis for such, reasonably demonstrating that equivalent data will be obtained
				  with the reduction or adjustment in monitoring;
(9) The District will provide at least one
				  week notice to the permittee of the intent to conduct a quality assurance field
				  audit of the sampling collection procedures;
(10) The water quantity and quality data
				  shall be submitted to the District no later than 60 days from the last day of
				  the sampling period being reported. Water quantity and quality data shall be
				  submitted to the District in an approved electronic format on a monthly
				  basis.
(11) All flow quantity
				  discharged from the property shall be calculated using a method proposed by a
				  Florida-registered Professional Engineer in a Calibration Report approved by
				  the District. A Calibration Report shall be required for each pump, culvert or
				  other discharge structure. The report shall also quantify uncontrolled off-site
				  discharges, such as overland sheet flow. Each Calibration Report shall contain,
				  at a minimum: data collection methodology, instrumentation and procedures; the
				  actual field data collected; the basis for the full operating range represented
				  by the data; the methodology for development of the calibration equation;
				  operational information needed to calculate flow with a temporary backup
				  methodology to be used if the primary equipment becomes inoperable; and the
				  final calibration equation and primary method for calculating the flow. Any
				  modification to the approved calibration shall require an application to modify
				  the existing permit.
(12) During
				  periods of off-site discharge, water quality composite samples shall be
				  collected by automatic sampler, preserved, and the composite sample shall be:
a) removed from the sample collection site
				  and delivered to the laboratory no later than 21 days from the time the first
				  individual sample was taken and,
b)
				  analyzed for total phosphorus no later than 28 days from the time the first
				  individual sample was taken.
