Proposal for Geotechnical Services,Phase 1 ESA and Database Review <br /> 2.57 Acres Site- <br /> Highway U.S.70A and Meadowland Drive,Hillsborough,North Carolina <br /> ECS Proposal Number 06P:16687-16689 <br /> NOW SCOPE SERVICES <br /> ASBESTOS SURVEY <br /> The site contains a two single family homes, reportedly scheduled for demolition. The purpose <br /> of this work is to survey the property to identify asbestos-containing materials (ACM) prior to <br /> demolition activities. ECS proposes to complete the asbestos survey as described below: <br /> 1. ECS will survey the property to identify ACM in general accordance with the U.S. <br /> Environmental Protection Agency (EPA) and NESHAPS requirements. Personnel <br /> performing the asbestos survey will be registered as Accredited Asbestos Inspectors <br /> within North Carolina. <br /> 2. ECS will begin by interviewing the site contact (if any) to learn available information <br /> regarding the past history of the building, including ages of materials, past renovations, <br /> maintenance, etc. <br /> 3. ECS will observe the property and identify the homogenous areas. Homogeneous areas <br /> are defined as sections of building materials appearing to have been installed in the <br /> same general time period, and are of uniform color and texture. Once homogeneous <br /> areas are identified, samples will be collected of materials suspected to contain asbestos <br /> in general accordance with NESHAP regulations. Specifically, samples will be collected <br /> from random locations of each homogeneous area. The number of samples collected <br /> from each homogeneous area will vary, based upon the following criteria: <br /> • Thermal Insulation Materials (piping, breeching, boiler insulation, etc.) - A <br /> minimum of three samples are required. Only patch areas (less than six square <br /> or linear feet) may have one sample collected. <br /> • Surfacing Materials (plaster, fireproofing, etc.) — A minimum of seven samples <br /> are to be taken for areas greater than 5,000 square feet; five samples for areas <br /> greater than 1,000 square feet, but less than 5,000 square feet; three samples <br /> for areas less than 1,000 square feet; one sample for patching material. <br /> • Miscellaneous Materials (flooring, adhesives, roofing, wallboard, etc.) — A <br /> minimum of two samples are required. <br /> 4. Samples collected from the site will be delivered to a laboratory accredited by the <br /> National Voluntary Laboratory Accreditation Program (NVLAP) for testing using for PLM <br /> (polarized light microscopy). A chain of custody will be maintained with the samples. <br /> 5. If one sample of a material from a homogeneous area is reported to contain greater than <br /> 1% asbestos, then by EPA definition, it is characterized as an asbestos-containing <br /> material. <br /> 6. This assessment will include limited destructive measures. However, due to the limited <br /> nature of our sampling, inaccessible materials may exist in chases, above fixed ceilings, <br /> behind permanent or attached fixtures, behind walls, etc. Suspect materials observed in <br /> inaccessible areas will have to be assumed positive or be evaluated at the time of <br /> discovery. <br /> 9 <br />
