Y ~' <br />Asbestos Containing <br />Materials Survey <br />4629 Nonh Overland Trail <br />La Porte, Colorado <br />• Rated fire doors throughout the site stmctures were assumed to contain <br />asbestos in internal linings. <br />• Electrical wiring or transformers may contain ACM products. <br />During this Survey, a total of 13 samples of gasket materials were collected throughout <br />the site (including in areas of 1980's construction). Eleven of the sampled gasket <br />materials (84 percent of gaskets sampled) contained asbestos in concentrations greater <br />t1t\ 1 percent. The typical asbestos content of the sampled gasket materials was 65 to <br />85 percent. These gaskets were both friable and non friable. <br />A total of 20 samples of window caulking/puay materials were collected throughout <br />the site. Eight of the sampled window materials (40 percent of sampled materials) <br />contained asbestos in concentrations greater than one percent. The typical asbestos <br />content of the sampled window materials was two to six percent. All observed window <br />caulkinglpu[ty materials were non-friable. <br />5. SummarvTahles and Appendices <br />Appendix A contains a Building Information Table that summarizes the number of <br />samples and the number of confirmed ACMs at each structure or azea. This table also <br />identifies the acronym used for each structure of area, which was incorporated into the <br />sample numbering system identified in the laboratory reports. Appendix B includes <br />Tables of Findings that also utilize the building acronyms in the sampled material <br />summaries. For example, the Machine Shop samples aze prefixed with the letters MS. <br />Following the building prefix, samples are described using an acronym for the type of <br />homogeneous material. An example would be PI for pipe insulation. The Findings <br />Table in Appendix B summarize the identified suspect and confirmed ACM <br />homogeneous materials. Laboratory results sheets are provided in Appendix C and <br />Photographs are attached in Appendix D. <br />6. ACM Condition <br />Identified ACMs were found to be in genera]ly good and intact condition. Damaged <br />pipe insulation, debris and associated contaminated soils were observed in localized <br />areas of the Finish Mill and Boiler House aeeas. Localized damage to pipe insulation <br />in the Plant Office and Quarry Shop were also observed. <br />~wonori~raor a~amvvp.a:,nu.os-a.a'roa.moo~me.um=..=n=m~wnm~l,rouzm~ <br />
