0208211 REPORT TO RAYMOND DESIGN ASSOCIATES OCTOBER 31, 2014 ASBESTOS INSPECTION LEEDS SCHOOL NORTHAMPTON, MA Submitted by: Kenneth Menzies, AI052108 PEER CONSULTANTS, P.C. Project Number: 6188-01 99 SOUTH BEDFORD STREET BURLINGTON, MA 01803 PEER Consultants Page 1 11/19/2014 rda northampton leeds asbestos inspection 2014-10-31.docx 1. Introduction Hazardous material sampling and analysis was conducted at the Leeds School in Northampton, MA to support designer services for a roof replacement. The objective was to inspect constructs, finishes and materials that may be affected by the project and may contain asbestos. All materials, which were to be disturbed by future renovation, were inspected. 2. Sampling Kenneth Menzies, PEER Consultants (MA Inspector License AI052108) surveyed the suspect asbestos containing building materials (ACBM) on October 17, 2014. Locations were selected with the guidance of Raymond Design Associates, Inc. (RDA) design engineers to facilitate the sampling of suspect building materials that will be disturbed by the future roof replacement. Therefore, all suspect hazardous building materials in the building were not necessarily sampled. Multiple samples of suspect materials were collected to meet the requirements of EPA and OSHA regulations. Suspect ACBM, which were identified, included roofing materials and roof penetration sealants. Samples were labeled, and appropriate chain-of-custody documentation was completed. The ACBM bulk samples were sent to AMA Analytical Services Inc. for laboratory analysis. 3. Analysis Bulk asbestos samples were analyzed using Polarized Light Microscopy (PLM) coupled with dispersion staining in accordance with the Environmental Protection Agency's (EPA) "Method for the Determination of Asbestos in Bulk Building Materials" (EPA/600/R-93/116, July 1993). AMA is accredited under the National Institute of Standards and Technology (NIST), National Voluntary Laboratory Accreditation Program (NVLAP), American Industrial Hygiene Association (AIHA), and the Commonwealth of Massachusetts (DOS). 4. Findings Visual inspection of selected materials indicated the presence of suspect asbestos containing building materials (ACBM) including roofing materials and roof sealants. The ACBM analytical data is provided in Appendix A. Samples are identified on a sample log (Appendix A). A summary of the ACBM results is provided in Table 1. An ACBM contains more than 1% asbestos and is regulated by the EPA and OSHA.
