3.5.3
Liquid Storage
Liquid collected from excavations and stockpiles shall be temporarily
stored in [220 L barrels] [[2000] [_____] L tanks] [55 gallon barrels]
[[500] [_____] gallon tanks]. Liquid storage containers shall be
water-tight and shall be located [as shown on the drawings] [_____].

SAMPLING
3.6.1
Sampling of Stored Material
**************************************************************************
NOTE: Additional samples are sometimes collected
from excavated material to determine the
contaminants present prior to treatment or disposal.
Composite samples are often collected from
stockpiled material. However, composite samples
cannot be taken if the samples are being analyzed
for volatile organic contaminants.
At sites with radioactive contamination, ex-situ
sampling of excavated material is typically
performed to ensure that the material meets disposal
facility acceptance criteria and, in some cases, to
assist with the preparation of shipping papers. The
ex-situ sampling regime is site-specific. It is
usually determined in consultation with the disposal
facility and its regulatory agency.
**************************************************************************
Samples of stored material shall be collected at a frequency of once per
[_____] cubic meters yards. Samples shall be tested for the following:
Chemical Parameter
Action Level
[_____]
[_____]
Stored material with contaminant levels that exceed the action levels shall
be treated [offsite. Analyses for contaminated material to be taken to an
offsite treatment facility shall conform to local, state, and federal
criteria as well as to the requirements of the treatment facility.
Documentation of all analyses performed shall be furnished to the
Contracting Officer. Additional sampling and analyses to the extent
required by the approved offsite treatment, storage or disposal (TSD)
facility shall be the responsibility of the Contractor and shall be
[performed at no additional cost to the Government] [subject to approval by
the Contracting Officer].] [onsite. Treatment shall be in accordance with
Section [_____].]
3.6.2
Sampling Liquid
**************************************************************************
NOTE: Liquid should generally be tested for the
same contaminants as are found in the contaminated
solid material being removed. The frequency of
testing should be determined on a site specific
basis. Offsite disposal will generally require
additional testing and analysis prior to disposal.
