Asbestos Project Size & Classification
(w) Asbestos Project. Work that involves the removal,
encapsulation, enclosure, repair or disturbance of friable or
non-friable asbestos, or any handling of asbestos material that may
result in the release of asbestos fibers. For the purpose of
compliance with this Part, an asbestos project shall include any
disturbance of asbestos fibers, and the planning, asbestos survey (as
per Subpart 56-5.1), design, background air sampling, inspection, air
sampling and oversight of abatement work, cleanup, and the handling of
all asbestos material subject to abatement, as well as the supervising
of such activities. Installation of friable ACM shall also be
considered an asbestos project. An asbestos project starts with Phase
I when the planning, asbestos survey, and design work begins or is
required to begin. The project shall not be considered completed until
Phase II D is complete. (See Table 1 Below).

(i) Large asbestos
project. An asbestos project involving the removal, disturbance,
enclosure, encapsulation, repair or handling of 160 square feet or
more of ACM, PACM or asbestos material or 260 linear feet or more of
ACM, PACM or asbestos material.
(ii) Small asbestos project. An asbestos project involving the
removal, encapsulation, enclosure, repair, disturbance or any handling
of more then 10 and less than 160 square feet of ACM, PACM or asbestos
material or more than 25 and less than 260 linear feet of ACM, PACM or
asbestos material.
(iii) Minor asbestos project. An asbestos project involving the
removal, disturbance, repair, encapsulation, enclosure or handling of
10 square feet or less of ACM, PACM or asbestos material, or 25 linear
feet or less of ACM, PACM or asbestos material.
(ah) Category I Non-Friable ACM. NESHAP classification -
Asbestos-containing packings, gaskets, resilient floor covering, and
asphalt roofing products, containing more than one percent (1%)
asbestos, that when dry, can not be crumbled, pulverized, or reduced
to powder by hand pressure.
(ai) Category II Non-Friable ACM. NESHAP classification - Any
material, excluding Category I Non-Friable ACM, containing more than
one percent (1%) asbestos, that when dry, can not be crumbled,
pulverized, or reduced to powder by hand pressure.
(aj) Class I Asbestos Work. OSHA term meaning activities
involving the abatement of Thermal Systems Insulation (TSI), and
surfacing ACM and PACM.
(ak) Class II Asbestos Work. OSHA term meaning activities
involving the abatement of ACM which is not TSI or surfacing material.
This includes, but is not limited to, the removal of
asbestos-containing wallboard, floor tile and sheeting, roofing and
siding shingles, and construction mastics.
(al) Class III Asbestos Work. OSHA term meaning Repair and
Maintenance operations, where no more than a minor quantity of ACM,
including TSI and surfacing ACM and PACM, is likely to be disturbed.
(am) Class IV Asbestos Work. OSHA term meaning Maintenance and
Custodial Activities during which employees contact but do not disturb
ACM or PACM and activities to clean up non-ACM dust, waste and debris
resulting from Class I, II and III activities. |
