m. Various textile materials
The A-E shall make prudent efforts to insure that asbestos detection and evaluation is
accomplished in sufficient detail to accurately identify the presence of the material or rule
out its existence. The Environmental Protection Agency Model Assessment Program shall
be used as the guide in defining homogeneous areas, establishing sampling protocols and
providing objective identification levels. Particular attention will be given to the correct
identification of damaged asbestos containing material with priority assessment based on
the EPA algorithm determining removal, encapsulation and/or repair.
3.19.2 Site Investigation of Suspect Materials
In cases where demolition is anticipated, friable asbestos material shall be removed
before other work proceeds. Preparation for work will include: (1) notification of regulatory
agencies, (2) acceptable arrangements to provide proper transportation, (3) verification of
personnel and contractor qualifications, and (4) assurance that administrative procedures
are completed relative to requirements for site surveillance when Regulated Asbestos
Containing Material (RACM) is present. Additionally, a report shall be submitted, after
review, during site surveillance to insure thoroughness in the data generated. This will
include the facility history file which includes a record history of maintenance and repairs
accomplished to date. Record data from NAVFAC MO-321, Facilities Management and
NAVFAC MO-322, Inspection of Shore Facilities will be summarized and presented in a
table format as part of the summary report.
3.19.3 Regulated Amounts of Asbestos Materials
Materials that have been objectively identified to contain asbestos are designated
Regulated Asbestos Containing Materials (RACM) only if they meet the legally defined
identification criteria. Required analysis includes Polarizing Light Microscopy (PLM),
Transmission Electro Microscopy (TEM), and X-Ray diffraction. The most commonly used
bulk identification procedure is the Petrographic Microscopy (PLM). This is currently the
legal methodology for bulk sample identification. This method has limitations based on the
limit of detection of the light microscope for diameters less than 0.5 microns. The
regulated asbestos containing materials are also defined as fibers of a specific length and
length to width ratio, as well as percent by area, rather than weight per volume. Where
identification is other than PLM and insertion of values or identifications by TEM is
presented by the A-E, this information must be supplemented with ashed weight data, as
well as fiber size and length, for consideration and decision making.
