of existing tanks and site features. The Contractor
will provide, as part of the Closure Report, a
detailed map showing exact location of the tank
prior to removal.
(3) Limits of pavement removal, fence removal, and
the location of ancillary equipment to be removed.
Hardened tanks are deep buried tanks as would be
found with some missile facilities. This should be
noted in the contract as they require deeper
excavations and possibly substantial demolition of
concrete.
Tanks will not be abandoned in place unless a waiver
is granted in accordance with state or local
requirements, LEE HQ U.S. Air Force for Air Force
Projects, and HQUSACE policy dated 31 July 1990, for
Formerly Used Defense Sites. Waivers will be
obtained prior to advertising the closure project.
Exceptions will be granted when requested in writing
on a case by case basis. Absence of contamination
must still be verified prior to closure and prior to
obtaining a waiver.
The designer must incorporate installation, state
and local requirements into this specification,
including the necessary approval processes,
licensing, or having their representative on site
during removal operations. In many cases, the state
or local jurisdiction has final authority on
approval of the Work Plan. While states often
enforce petroleum tank removal regulations, counties
and cities are sometimes delegated authority.
Petroleum sludge and contaminated media are often
considered "special wastes" and are subject to
regulations enforced by the State Fire Marshals
Office, local agencies, etc. Some states have
adopted federal rules for management of petroleum
waste.
State requirements usually involve testing,
analysis, and a report. The review by the state may
require additional testing or other work, and may
take several months; therefore, the designer must be
forewarned to investigate these requirements in
advance. Areas most likely to be impacted are waste
and tank disposal, tank cleaning, residue and soil
sampling and analysis, contaminated soil disposal or
remediation, reporting, and requirements for a clean
closure.
Petroleum sites which are known to have extensive
soil contamination or where groundwater
contamination is a possibility, should have a
Corrective Action Plan under Subtitle I of RCRA and
applicable state and local regulations; refer to EM
1110-3-178, Removal of Underground Storage Tanks
(USTs).
