(1) GENERAL.
(a) Unless otherwise directed by the
department, responsible parties shall conduct all necessary operation and
maintenance activities in accordance with this section and in compliance with
all applicable state or federal public health and environmental laws, whichever
are more stringent, until all applicable public health and environmental laws
are complied with as required in chs.
NR
700 to
754.
(b) Responsible parties shall operate and
maintain any cover systems, liners, physical hydraulic containment systems,
leachate collection systems, and gas collection, extraction, and management
systems at sites or facilities for which they are responsible until no longer
required by the department.
(c)
Responsible parties and property owners shall operate vapor mitigation systems
for which they are responsible until no longer required by the
department.
(d) Vapor mitigation
systems and remedial actions designed to address vapor migration shall be
monitored at a frequency determined by the department, to measure whether the
action taken has been effective in meeting the vapor action level.
(2)OPERATION AND MAINTENANCE PLAN.
Unless otherwise directed by the department, responsible parties shall submit
to the department an operation and maintenance plan when on-site maintenance
activities are necessary to implement, monitor or ensure the effectiveness of a
remedial or interim action. The plan shall outline all operation, monitoring,
and maintenance activities, from design through case closure under ch. NR 726
or through post-closure under ch. NR 727, as appropriate, including all of the
following information:
(a) The information
specified under s.
NR 724.05(2)
(e).
(b) A description of normal operation and
maintenance, including a schedule showing the frequency of each operation and
maintenance task.
(c) A contingency
plan for any anticipated or potential operation and maintenance problems,
including a description of techniques or activities to be conducted by the
responsible parties to resolve operation and maintenance problems.
(d) A description of routine monitoring and
analysis, including:
1. Long-term monitoring
required under s.
NR 724.17;
2.
Laboratory or field tests, test methods and sampling methods; and

dates.
(e) A description
of any site-specific or facility-specific record-keeping and reporting
requirements to document operation and maintenance activities, including:
1. Mechanisms for reporting system failures,
discharges of hazardous substances, environmental pollution and other
emergencies; and
2. Reports to be
submitted to the department, including the results of system and environmental
monitoring and the results of the monitoring well inspections meeting the

NR 716.13(14).
(f) A location map that includes the
locations and extent of features that need to be maintained, as well as the
extent of contamination.
(g) Final
construction specifications on any engineering control feature.
Note: Engineering controls may include a cover,
barrier, or vapor mitigation system.
(h) A list of prohibited
activities.
(i) A contact for
questions on specific actions and the inspection log.
(j) A statement of where more site-specific
information may be found.
Note: More site-specific information may be
found in the department's files.
(k) For vapor mitigation systems; a diagram
and photographs showing piping, venting, fans and manometer locations, vent
height and location, a description of how to verify that the vapor mitigation
system is operating properly, identification of prohibited activities to ensure
the continued effectiveness of the vapor mitigation system, and direction to
notify the department before any action is taken which would disturb operation
of the vapor mitigation system.
(L)
Air emission reporting and permitting, as applicable.
(m) Monthly manometer checks.
(n) Annual inspection of system
parts.
(3)PROGRESS
REPORTS. In addition to the general progress reporting requirements in s.
NR 700.11, responsible parties shall submit semi-annual
operation and maintenance progress reports to the department. Progress reports

supplied by the department. The department may require progress reports be
submitted at a different frequency than semi-annually.
Note: Operation and maintenance progress
reports should be submitted for both active and passive remediation systems.
Progress reports required under this subsection are not the same as
post-closure maintenance inspection logs for remedies such as performance
standard covers.
Note: Copies of remediation system operation
and maintenance reporting forms may be obtained from any regional office of the
department, or by writing to the Department of Natural Resources, Bureau for
Remediation and Redevelopment, P.O. Box 7921, Madison, Wisconsin 53707, or at
http://dnr.wi.gov/files/PDF/forms/4400/4400-194.pdf.
