Sec. 763.86  Sampling.

    (a) Surfacing material. An accredited inspector shall collect, in a 
statistically random manner that is representative of the homogeneous 
area, bulk samples from each homogeneous area of friable surfacing 
material that is not assumed to be ACM, and shall collect the samples as 
follows:
    (1) At least three bulk samples shall be collected from each 
homogeneous area that is 1,000 ft\2\ or less, except as provided in 
Sec. 763.87(c)(2).
    (2) At least five bulk samples shall be collected from each 
homogeneous area that is greater than 1,000 ft\2\ but less than or equal 
to 5,000 ft\2\, except as provided in Sec. 763.87(c)(2).
    (3) At least seven bulk samples shall be collected from each 
homogeneous area that is greater than 5,000 ft\2\, except as provided in 
Sec. 763.87(c)(2).
    (b) Thermal system insulation. (1) Except as provided in paragraphs 
(b) (2) through (4) of this section and Sec. 763.87(c), an accredited 
inspector shall collect, in a randomly distributed manner, at least 
three bulk samples from each homogeneous area of thermal system 
insulation that is not assumed to be ACM.
    (2) Collect at least one bulk sample from each homogeneous area of 
patched thermal system insulation that is not assumed to be ACM if the 
patched section is less than 6 linear or square feet.
    (3) In a manner sufficient to determine whether the material is ACM 
or not ACM, collect bulk samples from each insulated mechanical system 
that

is not assumed to be ACM where cement or plaster is used on fittings 
such as tees, elbows, or valves, except as provided under Sec. 
763.87(c)(2).
    (4) Bulk samples are not required to be collected from any 
homogeneous area where the accredited inspector has determined that the 
thermal system insulation is fiberglass, foam glass, rubber, or other 
non-ACBM.
    (c) Miscellaneous material. In a manner sufficient to determine 
whether material is ACM or not ACM, an accredited inspector shall 
collect bulk samples from each homogeneous area of friable miscellaneous 
material that is not assumed to be ACM.
    (d) Nonfriable suspected ACBM. If any homogeneous area of nonfriable 
suspected ACBM is not assumed to be ACM, then an accredited inspector 
shall collect, in a manner sufficient to determine whether the material 
is ACM or not ACM, bulk samples from the homogeneous area of nonfriable 
suspected ACBM that is not assumed to be ACM.
