OHC is the prime contractor for the RAO/LTM
contract. The Remedial Action
Operations/Long Term Management (RAO/LTM) work includes operating,
maintaining and/or monitoring Navy environmental restoration sites that
have ongoing remedial actions. Types of RAO includes: capped landfills,
groundwater treatment systems, phytoremediation, vegetative covers,
shoreline protection, soil vapor extraction, bioventing, steam or air
sparging, infiltration barriers, leach basins, storm water containment
systems, enhanced bioremediation, and free product recovery. Monitoring
and reporting of contaminants in accordance with approved monitoring plans
at sites with remediation systems or where monitored natural attenuation
may be occurring. The LTM work includes: Field data collection, sampling,
performing field and laboratory analyses, surveying, modeling of various
contaminants and geochemical indicators in monitoring and modeling results
to the RAO objectives that are generally outlined in either a decision
document, monitoring plan or applicable regulatory standards. Media
includes: air; groundwater; surface water; the marine environment;
sediments and soil; soil vapor gas; aquatic, benthic or terrestrial
organisms; bioassays.
Monitoring requirements includes
interpreting results for contaminants and geochemical indicators such as:
metals, volatile organic compounds (VOC); semi-volatile organic compounds
(SVOC); ordnance compounds; polychlorinated biphenyls (PCB)/pesticides;
polynuclear aromatic hydrocarbons (PAH) and total petroleum hydrocarbons (TPH);
water level; conductivity; redox potential; total organic carbon;
dissolved inorganic carbon; dissolved oxygen; hydrogen; methane; ethane;
nitrates; sulfates; and hydrogen sulfide.
RAO/LTM
services includes the following:
1)
Inspection and reporting of remediation systems operating conditions, the
use of supplies and replacement
equipment. This work
will include maintaining an O&M logbook for each system being
maintained.
2) Performing limited chemical
treatments, contaminant source removals, or other physical treatments to
improve efficiency of ongoing site remediation.
3) Establishing and abandoning of
monitoring wells in accordance with local, state, and federal regulatory
requirements.
4)
Evaluating Navy Activities compliance with activity-specific institutional
control plans.
5) Managing and/or disposing of
wastes resulting from the services provided by this contract, per Navy
Activity instructions.
6) Providing support with GIS,
CAD, and/or electronic data management.
7)
Developing technical memoranda, including but not limited to: the
findings of inspection, monitoring, testing, sampling, and modeling,
annual summary reports, CERCLA five-year reviews, various permitting
reports, and response complete reports.
8) Emergency repairs to
non-functioning remedial action systems.
9) Minor projects of constructing,
refurbishing, upgrading or reconfiguring remedial action systems to
improve system operations or remediation efficiency and to otherwise
reduce life-cycle costs at the site.
10) Designing and implementing
system modifications and revising O&M manuals to incorporate any new
requirements. On site design services to effect emergency or operational
repairs, construction or refurbishment of environmental systems, creation
of operating manuals, maintenance manuals.
