O&M Cost Elements.
a.
Many of the O&M cost elements listed in Exhibit 6-3 are incurred as part of
physical operation and maintenance activities. Project management and technical support are
professional/technical services to support O&M activities. Institutional controls may require
annual update or maintenance to ensure potential for exposure to site contamination or hazards is
reduced or minimized. Contingency, which covers unknowns or unanticipated conditions
associated with future O&M activities, should be added to the total of projected O&M costs (i.e.,
post-RA O&M), which are estimated only at the time of the RA report.
b.
O&M costs can vary and may be estimated for different time periods, depending
on the operating conditions and requirements. For example, the first five years of a groundwater
monitoring program may require semiannual sampling, while the next twenty years may only
require annual sampling. Likewise, an installed cap or cover may require more frequent
inspections during the first year of O&M than during subsequent years.
