Final Second Five-Year Review Report Fort Ord Superfund Site ...

6.5 Recommendations and Follow-Up Actions
Landfill Cap
Continue operation of the landfill gas treatment system to maintain landfill gas levels remain below
regulatory standards. Continue to inspect and monitor the OU 2 Landfills in accordance with the
Preliminary Draft Closure Operation and Maintenance Plan, Operable Unit 2 Landfills (Shaw, 2006a).
In the FS Addendum currently in development for Site 39, consideration is being given to placing
excavated soils on top of the existing cover on Cell E and then placing a new engineered cover.
Groundwater Treatment
The OU 2 Groundwater Remedy should continue to be implemented as designed until either aquifer
cleanup levels are reached or the next technical assessment is conducted. Adjustments to system
operation may be conducted to maximize extraction and treatment of contaminants while maintaining
capture of the plume.
6.6 Protectiveness Statement
The remedy will be protective of human health and the environment upon completion, and in the interim,
exposure pathways that could result in unacceptable risks are being controlled because of the presence of
Monterey County Ordinance 4011 and the CRUP.
