(a) Long-term care for each hazardous waste
management unit subject to the requirements of this section and ss.
NR 665.0118 to 665.0120 shall begin after completion of
closure of the unit and continue for a minimum of 40 years after that date. It
shall consist of at least both of the following:
1. Monitoring and reporting in accordance
with the requirements of subchs. F, K, L and N.
2. Maintenance and monitoring of waste
containment systems in accordance with the requirements of subchs. F, K, L and
N.
(b) Any time
preceding closure of a hazardous waste management unit subject to long-term
care requirements or final closure, or any time during the long-term care
period for a particular hazardous waste disposal unit, the department may
extend the long-term care period applicable to the hazardous waste management
unit or facility, if the department finds that the extended period is necessary
to protect human health and the environment (e.g., leachate or groundwater
monitoring results indicate a potential for migration of hazardous wastes at
levels which may be harmful to human health and the environment).
(2) The department may require, at
partial and final closure, continuation of any of the security requirements of
s.
NR 665.0014 during part or all of the long-term care
period under either of the following circumstances:
(a) Hazardous wastes may remain exposed after
completion of partial or final closure.
(b) Access by the public or domestic
livestock may pose a hazard to human health.
(3) Post-closure use of property on or in
which hazardous wastes remain after partial or final closure may never be
allowed to disturb the integrity of the final cover, liners or any other
components of the containment system, or the function of the facility's
monitoring systems, unless the department finds that either of the following
applies:
(a) The disturbance is necessary to
the proposed use of the property, and will not increase the potential hazard to
human health or the environment.
(b) The disturbance is necessary to reduce a
threat to human health or the environment.
(4) All long-term care activities shall be in
accordance with the provisions of the approved long-term care plan as specified
in s.
NR 665.0118.
