3.3 Regulated Material Survey <br />A walk- through was performed of the entire parcel where materials classified as regulated <br />wastes by the MPCA were identified and quantified. Regulated materials include but are not <br />limited to; mercury containing devices, fluorescent light bulbs, pcb containing ballasts, <br />Housed chemicals, etc. <br />4.0 RESULTS <br />4.1 Asbestos Sampling Results <br />A total of forty-one samples were collected of materials suspected of containing asbestos. <br />The results of the sampling show that the following materials were determined to be asbestos <br />containing and must be removed prior to demolition: <br />The duct seam wrap (paper) found on the ductwork located throughout the house was <br />determined to be asbestos containing. The paper is wrapped around the seams of the <br />ductwork which is found exposed in the basement and is concealed in wall and /or ceiling <br />cavities within the upper levels. LEGEND would estimate that there is approximately 150 <br />square feet of the paper present. The abatement contractor will have to demolish the plaster <br />walls and/or ceilings on the upper levels in order to expose the ducts that require abatement. <br />Vent locations on the second floor have been provided on Diagram #3 for reference <br />purposes. <br />The textured ceiling spray found throughout the first and second floors of the house was <br />determined to be asbestos containing. It is estimated that there is approximately 700 square <br />feet of the spray present in the house. The spray will have to be removed by a licensed <br />asbestos abatement contractor prior to demolition. <br />The black/gray caulk found around the perimeter of the chimney (on the exterior of the <br />house) was determined to be asbestos containing. There is approximately 50 linear feet of <br />the caulk present extending from the ground to the roof. The caulk should be removed by a <br />licensed asbestos abatement contractor prior to demolition. <br />Refer to Table #1 located in Appendix A for complete analytical results. The quantities <br />given are only estimates and should be verified by the abatement contractor prior to bidding. <br />4.2 Lead in Paint Sampling Results <br />A total of two samples were collected of paints that were in poor condition. The results <br />show that both paints were determined to be non -lead -based paints and therefore, no <br />stabilization is required. <br />Page 2 of 3 <br />6 <br />
