Termination of Postclosure Maintenance
Section 1100.530 Termination of Postclosure Maintenance
At the end of the postclosure maintenance period, the owner
or operator must submit a certification by a PE or PG and an affidavit by the
owner or operator demonstrating that, due to compliance with the postclosure
maintenance plan and the postclosure maintenance requirements of this Part,
postclosure maintenance is no longer necessary because:
a) Vegetation has been
established on all nonpaved areas;
b) The
surface has stabilized sufficiently with respect to settling and erosion so
that further stabilization measures required by the postclosure maintenance
plan are no longer necessary; and
c) The
owner or operator has completed all requirements of the postclosure maintenance
plan.
