Fla. Admin. Code Ann. R. 62-673.620 - Closure Procedures
(1) Closing
inspections. The Department shall specify in the closure permit or closure plan
which particular closing steps or operations must be inspected and approved by
the Department before proceeding with subsequent closure actions.
(2) Final survey and record drawings. A final
survey shall be performed after closure is complete by an engineer or a
registered land surveyor to verify that final contours and elevations of the
phosphogypsum stack system are in accordance with the plan as approved in the
permit. Aerial mapping techniques which provide equivalent survey accuracy may
be substituted for the survey. The survey or aerial mapping information shall
be included in a report along with information reflecting the record drawings
of the phosphogypsum stack system. Contours should be shown at no greater than
five-foot intervals. The owner or operator shall submit this report to the
Department in accordance with the closing schedule.
(3) Certification of closure construction
completion. A certification of closure construction completion, signed, dated
and sealed by the engineer of record, shall be provided to the Department upon
completion of closure.
(4) Official
date of closing. Upon receipt of the documents required in subsections (2) and
(3), of this rule, the Department shall, within 30 days, acknowledge by letter
to the facility operator that notice of termination of operations and closing
of the phosphogypsum stack system has been received. The date of this letter
shall be the official date of closing for purposes of determining the long-term
care period.
(5) Use of closed
phosphogypsum stack systems. Closed phosphogypsum stack systems, if disturbed,
are a potential hazard to public health, groundwater and the environment. The
Department retains regulatory control over any activities which may affect the
integrity of the environmental protection measures such as the final cover,
drainage, liners, monitoring system, or leachate and stormwater controls.
Consultation with the Department is required before conducting activities at
the closed phosphogypsum stack systems.
