(a) The operator
shall implement the closure plan approved by the Department under §
273.192 (relating to closure
plan).
(b) At least 180 days before
implementation of a closure plan, the operator shall review its approved
closure plan to determine whether the plan requires modification, and shall
submit proposed changes to the Department for approval under §
271.222 (relating to permit
modification).
(c) If groundwater
degradation exists at closure or occurs after closure, a person shall meet one
of the following:
(1) Continue to implement
an approved abatement plan.
(2)
Submit an application for a closure plan modification in accordance with the
procedures for a major permit modification. The operator shall select one or
more remediation standards that will be met in accordance with the final

271.342 (relating to final closure
certification).
(d) An
application for a closure plan modification shall include the following:

in accordance with §
271.144 (relating to public notice
and public hearings for permit modifications), the frequency of monitoring for
a parameter for which quarterly monitoring is required under §
273.284 (relating to sampling and
analysis) to a semi-annual frequency if the operator demonstrates the
following:
(1) The parameter has not caused
or contributed to groundwater degradation.
(2) Based upon the characteristics of the
waste at the facility and the performance of the liner system, the parameter is
unlikely to cause or contribute to groundwater degradation in the
future.
(f) The
Department may modify the frequency of monitoring for a parameter for which
semi-annual monitoring was approved under subsection (e) to an annual basis if
the results of semi-annual monitoring continue to demonstrate the following:
(1) The parameter has not caused or
contributed to groundwater degradation.
(2) Based upon the characteristics of the
waste at the facility and the performance of the liner system, the parameter is
unlikely to cause or contribute to groundwater degradation in the
future.
(g) The
Department may reinstate the requirement of quarterly monitoring for any
parameter monitored under subsection (e) or (f) if the Department has reason to
believe that the parameter may cause or contribute to groundwater
degradation.
