3.0 SURVEY The survey was conducted on August 24, 2000 by Ms. Jennifer Wolff and Mr. Matt Schemmel, both of DPRA and licensed asbestos building inspectors. Copies of the certifications for Ms. Wolff and Mr. Schemmel are attached as Appendix A. Lonnie Brokke, of the city of Roseville, provided access to the subject property. 3.1 Asbestos Samples of suspect ACM were collected utilizing random sampling procedures. Similar systems and materials were grouped into "homogeneous areas of building materials." Multiple random samples were taken of materials in accordance with the EPA-AHERA guidelines. The samples taken were designated "A, B, C" etc. Sample locations were determined using a random sampling process for each homogeneous material and are shown on Figure 1. Samples were collected by removing a small representati ve sample of the material and sealing it in a plastic bag. Water was sprayed on the material to control dust. The bag was then labeled with the sample number. , .. . DPRA reviewed a previous asbestos survey report for the subject property and was able to eliminate the sampling of the tectum ceiling, one type of ceiling tile, one type of floor tile, and one type of wallboard on the basis of the findings of that report. The 9" by 9" floor tile in the previous report was found to be ACM. The previous report also identified pipe fittings and water heater .insulation to be ACM; however, upon inspection, they have been replaced with fiberglass insulation and are thus non-asbestos containing material. i I I DPRA collected 126 samples of suspect asbestos-containing materials. The samples were submitted to McCall and Spero Environmental, Inc. (MSE) for PLM analysis. The samples were tested until positive, which indicates that the homogeneous materials were analyzed until one of the samples was determined to contain asbestos. A total of 105 samples were analyzed.
