[Stockpiled contaminated soil shall be sampled and preserved in accordance
with the approved Sampling and Analysis Plan, and Section 01450A CHEMICAL
DATA QUALITY CONTROL.] [Sampling locations, number and specific procedures
shall be as required by the [State of [_____]] [implementing agency] and
the disposal facility.]

Analysis
**************************************************************************
NOTE: Hydrocarbon tests may vary vastly from state
to state. Designer should consult the latest state
requirements for the appropriate hydrocarbon test
methods and coordinate with Section 01450A CHEMICAL
DATA QUALITY CONTROL.
The designer will take into consideration that
testing of stockpiled soils and testing of the
excavation pit to confirm "clean closure" may
require different testing. Stockpiled materials
testing is performed relative to disposal criteria,
confirmation soil testing from the pit is tested to
demonstrate clean closure.
**************************************************************************
Soil samples from the excavation and stockpiled material shall be tested in
accordance with the approved Sampling and Analysis Plan, and Section 01450A
CHEMICAL DATA QUALITY CONTROL for the following parameters: [total
petroleum hydrocarbon (TPH)] [benzene, ethylbenzene, toluene, xylene
(BETX)] [toxicity characteristic leaching procedure (TCLP)] [the following
constituents: [_____]]. Copies of all test results shall be provided to
the Contracting Officer.
3.11
BACKFILLING
**************************************************************************
NOTE: Coordinate with the IA regarding the maximum
contaminant levels allowable for clean closure, and
if waste from one stockpile can be used as backfill
for another. Coordinate with the user concerning
preferences in regard to leaving excavations open
pending lab results, state inspector's evaluations,
road closures and other factors. Lab turnaround
time plays a critical role in the duration of
excavations left open and times must be coordinated.
If field analysis is allowed by the state
inspector, this would reduce or eliminate turnaround
time concerns.
If the Government or state will analyze samples,
revise this paragraph and give the length of time
the Contractor should expect the excavation to be
open.
If additional constituents require analyses to meet
state/local closure requirements, include the
appropriate limits in this paragraph and include the
same limits in the definition for clean fill.
Add applicable requirements for backfilling the
