permissible to use contaminated soil materials for
backfill in tank and piping excavations. Specifier
shall get approval from local regulating authority
before using contaminated soil materials.
If contaminated soil materials are approved for
backfill, delete paragraph.
**************************************************************************
Soils with OVA/FID readings of [10] [_____] ppm or greater shall be further
sampled and tested for TPH and for BTEX in accordance with EPA 530/F-93/004
and EPA 600/4-79/020, and for toxicity characteristic leaching procedure
(TCLP) for lead if leaded gasoline was stored in or near the underground
tank being removed. For stockpiled soils, provide a minimum of one test
for every [77] [_____] cubic meters [100] [_____] cubic yards for TPH, and
one test for every [77] [19] [_____] cubic meters [100] [25] [_____] cubic
yards for BTEX and TCLP. Soils that contain [50] [_____] ppm or more TPH,
[10] [_____] ppm or more BTEX or have TCLP reading of [10] [_____] ppm lead
or virgin petroleum products are considered contaminated materials. Soils
which are less than the above may be used as clean fill. Furnish results
to the Contracting Officer within 24 hours after the results are obtained.

Testing Under Tank After Removal of Tank
**************************************************************************
NOTE: Testing requirements are dependent on
regulations applicable to the location where
underground tanks and piping are being removed.
Specifier must verify number of tests required and
required location for tests.
**************************************************************************
If tank is [6] [_____] m [20] [_____] feet or less in length, take [two]
[_____] samples. Each sample shall be [0.60] [_____] m [2] [_____] feet
from each end of the tank and [0.60] [_____] m [2] [_____] feet below the
bottom of the excavation. If the tank is greater than [6] [_____] m [20]
[_____] feet, take [three] [_____] samples. Two samples shall be [0.60]
[_____] m [2] [_____] feet from each end of the tank and [0.60] [_____] m
[2] [_____] feet below the bottom of the excavation. A third sample shall
be taken from the middle of the tank area and [0.60] [_____] m [2] [_____]
feet below the bottom of the excavation. Samples shall be analyzed for
TPH, BTEX, and TCLP. Sampling and analysis shall conform to standards
specified above for stockpiled soils.
Soil shall be sampled and analyzed
for TPH, and for BTEX in accordance with EPA 530/F-93/004 and EPA
600/4-79/020, and a TCLP test if soil is contaminated with leaded gasoline.
Soils that contain [50] [_____] ppm or more TPH, [10] [_____] ppm or more
BTEX, or have TCLP reading of [10] [_____] ppm of lead or virgin petroleum
products are considered contaminated materials. Soils which are less than
the above may be used as clean fill. Furnish results to the Contracting
Officer within 24 hours after the results are obtained. Along with the
results furnish a sketch showing underground tank, sampling location, and
extent of excavations.
