on fittings (e.g., tees, elbows, valves). Bulk samples are not required where the TSI has been
identified as fiberglass, foam glass, rubber, or other non-ACM.
c. Miscellaneous Material
The Contractor shall collect samples in a quantity sufficient to determine whether the material
contains asbestos at a concentration of greater than 1%.
Category I Nonfriable Asbestos-Containing Material
Collect asbestos-containing packing, gaskets, resilient floor covering, and asphalt roofing
product samples in a quantity sufficient to determine whether the material contains asbestos at a
concentration of greater than 1%.
Category II Nonfriable Asbestos-Containing Material
Collect asbestos-containing material excluding Category I nonfriable asbestos-containing
material that when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure,
in sufficient quantities to determine whether the material contains asbestos at a concentration of
greater than 1%.
[The Contractor shall photograph each sample location.]

Waste Characterization and Quantity Estimation
******************************************************************************
NOTE: The intent of characterizing waste prior to the actual project work
(demolition or renovation) is to determine if the anticipated waste stream will be
hazardous or non- hazardous waste due to lead. The determination is
accomplished by the Toxicity Characteristic Leaching Procedure (TCLP) test and
must be performed by an NLLAP laboratory capable of performing the test. To
prepare for the test, the Contractor must estimate the anticipated waste stream that
will be produced by the demolition/renovation or remodeling, and estimate the
approximate quantities of each building material making up the waste stream as a
percent of the total, regardless of the material's LBP content (see Table B-4).
Materials that are to be recycled (typically metal) should be excluded from the
sample. The Contractor must then collect field samples of each material in
quantities sufficie nt for the laboratory to take samples of each material
proportional to the percent of each material to the whole. For instance, if the
intent is to demolish a building, there should be representative samples and
approximate percent quantities to the whole sample of footers/foundations, wall
studs, roofing material, glass, brick facade, in addition to painted interior and
exterior materials, such as doors, wall, ceilings, windows, etc. The Contractor
provides the laboratory each of the representative samples. The lab then typically
composites a 120-gram sample, and performs the TCLP test, using the percent
