2.2.1.1
Sample Location Documentation
Upon completion of the walk-through survey, and prior to actual sampling, the Contractor shall
clearly mark, number and otherwise uniquely identify all homogenous areas of suspected ACM and
samples to be taken, by marking the locations on the floor plan or sketch including room layout.
The resultant information shall be compiled and labeled the "Sample Location Documentation"
before actual sampling commences. Sampling shall be completed immediately following the walk-
through survey and the documentation of sample locations, prior to exiting the facility.
The COTR reserves the right to audit the Sample Location Documentation, at any time during the
course of the project. The Sample Location Documentation shall be included as an attachment to
the Asbestos Sampling Plan, and shall be submitted as a part of the Asbestos Survey and
Assessment Report.
2.2.2
Collection of Bulk Samples
The Contractor shall ensure that all personnel collecting bulk samples are currently certified as
AHERA Asbestos Inspectors. The Contractor shall collect bulk samples following the guidance
provided in PWTB 420-70-8, Chapter 8-3, "Bulk Sample Collection" and in the ACM in Schools
Rule found in 40 CFR 763.86. The Contractor shall use the specific procedures and techniques for
bulk sample collection described in Section I of the USEPA "Model EPA Curriculum for Training
Building Inspectors". The Contractor shall collect a minimum of three bulk samples per
homogeneous area that is 1000 ft2 or less, except as provided in 40 CFR 763.87, for all surfacing
materials. Suspect surfacing materials (i.e., sprayed or troweled on) shall be sampled randomly
following the USEPA document entitled "Asbestos in Building Simplified Sampling Scheme for
Friable Surfacing Materials".
The Contractor shall collect a minimum of three samples for TSI that is not assumed to be ACM.
If a TSI section is less than six linear feet or six square feet, a minimum of 1 bulk sample shall be
collected, unless the TSI is assumed to be ACM.
[Destructive bulk sampling of [any] [exterior] [roofing] miscellaneous materials is not authorized.]
[Destructive bulk sampling of miscellaneous materials is authorized, and sample location shall be
coordinated with the facility management.] The Contractor shall collect the minimum number of
bulk samples of miscellaneous materials following the guidance in the "AHERA 3,5,7 Rule".
2.2.3
Sample Identification
A unique sample identification code number shall be used for all bulk samples. The number is
intended to facilitate sample tracking without revealing the identity of the sample to the laboratory.
All sample containers shall be labeled immediately upon collection of the sample. Information on
sample labels shall include the sample identification printed with a waterproof marker. Labels are
used for identification and to preserve sample integrity.
2.2.4
Sample Chain-of-Custody
The Contractor shall follow a standard chain-of-custody protocol to document and ensure a
continuous record of sample possession from the time of sample collection to the samples' receipt
