<br />looking for anomalies. Any identified anomalies (i.e., utilities, underground storage tanks) will be marked
<br />on the surface using chalk or paint, as appropriate for documentation to others.
<br />Task 3 — Survey for Asbestos - Containing Materials
<br />The purpose of the asbestos survey is identification or elimination of building materials as of Asbestos -
<br />Containing Materials (ACM) in accordance with the National Emission Standard of a Hazardous Air
<br />Pollutant (NESHAP) for Asbestos 40 CFR 61, Subpart M, and 326 IAC 14 -10, Emission Standards for
<br />Asbestos; Demolition and Renovation Operations.
<br />The survey of the property for ACM will begin with a walk- through of the existing structure to document
<br />locations of friable and non - friable materials that may be present. Friable materials are those that can be
<br />pulverized or reduced to powder by moderate pressure, such as spray - applied fireproofing and acoustical
<br />materials, ceiling tiles and most thermal system insulation. Non - friable materials are those that cannot be
<br />crumbled easily, such as resilient floor tiles and cement asbestos (Transited) board. Although emphasis
<br />is on detecting friable materials, the possible presence of non - friable ACM must also be considered, as
<br />during renovation, non - friable materials may be pulverized or otherwise damaged so as to release
<br />asbestos fibers into the air.
<br />The sampling strategy for any suspect material is dependent upon the application, the area of coverage
<br />and the uniformity of the application. In accordance with the United States Environmental Protection
<br />Agency (USEPA) 40 CFR 763.83, Subpart E definitions, there are three types of asbestos - containing
<br />materials (ACM): 1) Thermal System Insulation (TSI), 2) Surfacing Materials (S), and 3) Miscellaneous
<br />Materials (Misc). Thermal System Insulation is material used to prevent heat loss or gain and prevent
<br />condensation, and includes: pipe insulation, valve and fitting insulation, boiler system insulation,
<br />breeching insulation and tank insulation. Surfacing materials are spayed on, troweled on or materials
<br />otherwise applied to a surface and include: acoustical plaster, fireproofing on structural members or
<br />decking, or on surfaces for the purpose of fireproofing. Miscellaneous or "other" materials are those that
<br />are not characterized as TSI or Surfacing Materials, and include: ceiling tile, floor tile, roofing felt, cove
<br />base and associated adhesive or mastic.
<br />Each suspect ACM (i.e., TSI, Surfacing or Miscellaneous material) identified from the initial walkthrough
<br />of the facilities will be placed into a group of similar materials identified as a homogeneous area.
<br />Homogeneous areas are identified as materials of the same type, color, texture and estimated age of
<br />installation. Upon identifying homogeneous areas, representative samples will be collected on a random
<br />basis. The number of samples collected depends upon the type of material (TSI, S, Misc) and the
<br />amount of the material, in accordance with the following, based on OSHA regulations detailed in 29CFR
<br />1926.1001).
<br />Type of Material
<br />Amount
<br />Number of Samples
<br />Surfacing Materials
<br />< 1,000 SF
<br />Minimum of 3 samples
<br />1,000 to 5,000 SF
<br />Minimum of 5 samples
<br />> 5,000 SF
<br />Minimum of 7 samples
<br />Thermal System Insulation
<br />< 6 LF /SF
<br />1 sample required
<br />, 6 LF /SF
<br />Minimum of 3 samples
<br />Misc /Other
<br />Any
<br />Sufficient to determine ACM /Non -ACM
<br />General in accordance with 3/5/7 protocol for
<br />Surface Materials
<br />Notes: LF — Linear Feet, SF — Square Feet
<br />The asbestos - containing material (ACM) survey will be performed by an Indiana Certified Asbestos
<br />Building Inspector. At any time during the survey, the Inspector can elect to assume that a specific
<br />material is asbestos - containing, and thereby forego sampling requirements for that homogeneous area.
<br />Samples, as appropriate, will be collected in general conformance with the procedures outlined in the
<br />Asbestos Hazard Emergency Response Act of 1986 (AHERA).
