Fla. Admin. Code Ann. R. 62-610.464 - Storage Requirements
(1)
System storage shall not be required where another permitted reuse system or
effluent disposal system is incorporated into the system design to ensure
continuous facility operation in accordance with the requirements of Chapter
62-600, F.A.C. If system storage is not required, provision of flow
equalization or storage should be evaluated in the engineering report to ensure
that reclaimed water flows will match the demand pattern during a diurnal
cycle.
(2) Unless exempted by
subsection 62-610.464(1),
F.A.C., system storage ponds shall have capacities determined as follows.
Requirements for system storage pond capacity shall be as contained in Rule
62-610.414, F.A.C., for
restricted access slow-rate land application systems. System storage or a
limited wet weather discharge authorization shall be required for wet weather
conditions. At a minimum, system storage capacity shall be the volume equal to
three times that portion of the average daily flow of the total reuse capacity
for which no alternative reuse or disposal system is permitted.
(3) In addition, a separate, off-line system
for storage of reject water shall be provided, unless another permitted reuse
system or effluent disposal system is capable of discharging the reject water
in accordance with requirements of Chapter 62-600, F.A.C. Reject water storage
shall have sufficient capacity to ensure the retention of reclaimed water of
unacceptable quality. At a minimum, this capacity shall be the volume equal to
one day flow at the average daily design flow of the treatment plant or the
average daily permitted flow of the reuse system, whichever is less. Provisions
for recirculating this reject water to other parts of the treatment plant for
further treatment shall be incorporated into the design.
(4) Requirements for system storage and
off-spec water holding ponds shall be as contained in Rule
62-610.414, F.A.C., except for
the following:
(a) System storage ponds do
not have to be lined.
(b) Off-spec
reclaimed water storage ponds shall be lined or sealed to prevent measurable
seepage.
(c) Existing or proposed
lakes or ponds (such as golf course ponds) are appropriate for storage of
reclaimed water and stormwater management if all Department rules are met and
the use of lakes or ponds for reclaimed water storage will not impair the
ability of the lakes or ponds to function as a stormwater management system.
Rule 62-610.830, F.A.C., contains
permitting requirements for these types of storage lakes or ponds. Lakes or
ponds (such as golf course ponds) used to store reclaimed water are not
required to meet the storage pond design, construction, and operation
requirements in subsections
62-610.414(7) and
(8), F.A.C.
(5) The permittee shall maintain an inventory
of storage systems. The inventory shall be submitted to the Department at least
30 days before reclaimed water will be introduced into any new storage systems.
The inventory shall include the following:
(a)
Name or identifier for the storage system.
(b) Location of the storage system
(latitude/longitude).
(c) Function
of the storage system (system storage or reject storage).
(d) Type of facility (covered tank, uncovered
tank, lined pond, unlined pond).
(e) Indication of whether or not the storage
facility is a water of the state or discharges to a water of the
state.
(f) Distances to the nearest
public water supply wells and to the nearest potable water supply wells which
are not public water supply wells.
