The inspection was conducted <br /> by Sheltertech representative George Zortman (Minnesota Asbestos Inspector #A11455). <br /> The site was occupied by a one story, multi-level residential building constructed of wood <br /> frame walls with vertical wood/brick siding, flat roof, and a full basement. The house was <br /> heated with five natural gas forced-air furnaces and cooled with four central air conditioning <br /> systems. The presence of vermiculite was not identified within the attic or those wall cavities <br /> accessible to visual inspection. According to Hennepin County property records, the building <br /> was constructed in 1970. <br /> Laboratory Analysis <br /> After completion of the field sampling activities, the bulk samples and accompanying chain-of- <br /> custody (COC) documentation were submitted to Carolina Environmental, Inc. of Cary, North <br /> Carolina. Carolina Environmental, Inc. participates in the analysis of standard bulk samples <br /> through the National Voluntary Laboratory Accreditation Program. Its NVLAP Accreditation <br /> number is 101768-0. The examination for the presence and identification of asbestos fibers in <br /> bulk samples was performed using crossed polarized light microscopy (PLM) and dispersion <br /> staining particle identification technique in accordance with USEPA, Method for the <br /> Determination of Asbestos in Bulk Building Materials, EPA 600/R-93/116 (July, 1993). Bulk <br /> samples containing multiple layers were analyzed per layer. The samples were analyzed <br /> utilizing a positive stop method, where indicated. <br />
