and full TCLP including ignitability, corrosivity and reactivity. Backfill
shall contain less than [100] [_____] parts per million (ppm) of total
petroleum hydrocarbons (TPH) and less than [10] [_____] ppm of the sum of
Benzene, Toluene, Ethyl Benzene, and Xylene (BTEX) and shall not fail the
TCPL test. TPH concentrations shall be determined by using EPA 600/4-79/020
Method 418.1. BTEX concentrations shall be determined by using EPA
SW-846.3-3 Method 5030/8020. TCLP shall be performed in accordance with
EPA SW-846.3-3 Method 1311. Provide Borrow Site Testing for TPH, BTEX and
TCLP from a composite sample of material from the borrow site, with at
least one test from each borrow site. Material shall not be brought on
site until tests have been approved by the Contracting Officer.

BURIED WARNING AND IDENTIFICATION TAPE
**************************************************************************
NOTE: Delete paragraph if tape is not required in
the project. The use of a plastic warning tape for
identification is mandatory for buried hazardous
utilities such as electrical conduit, gas lines,
fuel lines, high pressure nitrogen, high pressure
water and steam lines, domestic sewage force mains,
industrial waste force mains and industrial sewers
carrying hazardous, explosive, or toxic waste.
Coordinate color codes with other specification
sections and conform, if possible, to local practice
for identifying buried utilities.
**************************************************************************
[Polyethylene plastic] [and] [metallic core or metallic-faced, acid- and
alkali-resistant, polyethylene plastic] warning tape manufactured
specifically for warning and identification of buried utility lines.
Provide tape on rolls, 75 mm 3 inch minimum width, color coded as specified
below for the intended utility with warning and identification imprinted in
bold black letters continuously over the entire tape length.
Warning and
identification to read, "CAUTION, BURIED (intended service) LINE BELOW" or
similar wording. Color and printing shall be permanent, unaffected by
moisture or soil.

2.2.1
Warning Tape for Metallic Piping
Acid and alkali-resistant polyethylene plastic tape conforming to the
width, color, and printing requirements specified above. Minimum thickness
of tape shall be 0.08 mm 0.003 inch. Tape shall have a minimum strength of
10.3 MPa 1500 psi lengthwise, and 8.6 MPa 1250 psi crosswise, with a
maximum 350 percent elongation.
