NPDES requirements must be considered for onsite
disposal of liquids.
**************************************************************************
Liquid collected from [excavations] [storage areas] [decontamination
facilities] shall be sampled at a frequency of once for every [2,000]
[_____] L [500] [_____] gallons of liquid collected. Samples shall be
tested for the following:
Chemical Parameter
Action Level
[_____]
[_____]
Liquid with contaminant levels that exceed action levels shall be treated
[offsite. Analyses for contaminated liquid 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 analysis to the extent required by the approved
offsite treatment, storage or disposal (TSD) facility receiving the
material 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 [_____].]
3.6.3
Sampling Beneath Storage Units
**************************************************************************
NOTE: At some sites, samples are collected to
verify the soil on which a storage unit is placed
has not become contaminated.
Sampling along any connecting pipelines that
transport contaminated liquid may also be
appropriate. A standard practice is to sample at 6
m (20 foot) intervals under piping and at
connections such as bends, elbows, or tees.
**************************************************************************
Samples from beneath each storage unit shall be collected prior to
construction of and after removal of the storage unit. Samples shall be
collected at a frequency of one per each [_____] square meters yards from a
depth interval of [0 to 0.15] [_____] m [0 to 0.5] [_____] feet and shall
be tested for the following:
Chemical Parameter
Action Level
[_____]
[_____]
Based on test results, soil which has become contaminated above action
levels shall be removed at no additional cost to the Government.
Contaminated material which is removed from beneath the storage unit shall
be handled in accordance with paragraph Sampling of Stored Material. As
directed by the Contracting Officer and at no additional cost to the
Government, additional sampling and testing shall be performed to verify
areas of contamination found beneath stockpiles have been cleaned up to
below action levels.
