the same type of work is being performed, provide area sampling at least
once every work shift close to the work inside the enclosure, outside the
clean room entrance to the enclosure, and at the exhaust opening of the
local exhaust system. If sampling outside the enclosure shows airborne
levels have exceeded background or 0.01 fibers per cubic centimeter,
whichever is greater, stop all work, correct the condition(s) causing the
increase, and notify the Contracting Officer immediately. [Where alternate
methods are used, perform personal and area air sampling at locations and
frequencies that will accurately characterize the evolving airborne
asbestos levels.]]
[The PQP shall provide personal sampling as indicated in 29 CFR 1926.1101.
At the same time the NC will provide area sampling close to the work inside
the enclosure, outside the clean room entrance to the enclosure, and at the
exhaust opening of the local exhaust system. In addition, provided the
same type of work is being performed, the NC will provide area sampling
once every work shift close to the work inside the enclosure, outside the
clean room entrance to the enclosure, and at the exhaust opening of the
local exhaust system. If sampling outside the enclosure shows airborne
levels have exceeded background or 0.01 fibers per cubic centimeter,
whichever is greater, stop all work, correct the condition(s) causing the
increase, and notify the Contracting Officer immediately. [Where alternate
methods are used, perform personal and area air sampling at locations and
frequencies that will accurately characterize the evolving airborne
asbestos levels.]]
3.2.7.3
Sampling After Final Clean-Up (Clearance Sampling)
**************************************************************************
NOTE: The designer shall research the State,
regional and local laws, regulations, statutes,
etc., to determine whether "aggressive" air sampling
is required. However, always use aggressive air
sampling techniques after encapsulation type
abatement efforts.
**************************************************************************
**************************************************************************
NOTE: Normal practice is to have the Contractor
hire one independent Private Qualified Person (the
PQP) to perform all required functions. However,
some applicable laws forbid this approach and will
dictate when the PQP, the NC or both will be
required to perform the function involved. However,
the Contractor shall always hire a PQP.

NOTE: The designer shall research the State,
regional and local laws, regulations, statutes,
etc., to determine whether TEM analysis is required
and the number of samples required.
**************************************************************************
Provide area sampling of asbestos fibers [using aggressive air sampling
techniques as defined in the EPA 560/5-85-024] and establish an airborne
asbestos concentration of less than 0.01 fibers per cubic centimeter after
final clean-up but before removal of the enclosure or the asbestos work
control area. After final cleanup and the asbestos control area is dry but
