The number of samples collected will be determined using the following criteria: <br /> • Thermal Insulation Materials (piping, breeching, boiler insulation, etc.)-A minimum of three <br /> (3) samples will be collected with the exception of one(1)sample being collected from patch <br /> areas that are less than 6 square or linear feet in size. <br /> • Surfacing Materials (plaster, fireproofing, etc.) - A minimum of seven (7) samples will be <br /> collected for areas greater than 5,000 square feet;five(5)samples collected for areas greater <br /> than 1,000 square feet, but less than 5,000 square feet; and three (3) samples collected for <br /> areas less than 1,000 square feet. <br /> • Miscellaneous Materials(flooring, adhesives, roofing,wallboard, etc.)-A minimum of two(2) <br /> samples are required. <br /> 5. Samples collected from the second floor of the building will be delivered to a laboratory that has <br /> been accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) for testing by <br /> polarized light microscopy(PLM). Chain of custody forms will be maintained with the samples. <br /> 6. The assessment will not include destructive measures to look in chases, above fixed ceilings, <br /> behind permanent or attached fixtures, behind walls, etc. Materials located below carpeting corners, <br /> behind removable exterior siding and behind removable fixtures will be sampled if accessible during <br /> the time of the assessment. Suspect materials observed in inaccessible areas will have to be assumed <br /> positive or be evaluated at the time of discovery. <br /> 7. If one sample of a material from a homogeneous area is reported to contain greater than 1% <br /> asbestos, then by EPA definition,the material is characterized as an ACM. <br /> 8. An asbestos assessment report will be provided at the completion of our work. This report <br /> will include a description of the background information provided, assessment and laboratory <br /> procedures, results obtained and a discussion presenting our evaluation and recommendations, <br /> should ACMs be identified. <br /> The non-invasive assessment will target accessible interior portions of the second floor of the subject <br /> building. The assessment at this time does not include the exterior of the structure or destructive <br /> testing that may require access within wall, ceiling, or floor cavities to access hidden materials. ECS <br /> will rely on Orange County Asset Management Services to provide access to the subject building(s). <br /> While this assessment will generally be non-destructive, the nature of an ACM assessment requires <br /> limited destructive means to collect bulk samples (approximately one square inch in size) of suspect <br /> ACMs. ECS will attempt to perform bulk sampling in discrete areas. Patching of or repair to sample <br /> locations will not be performed by ECS. During the assessment, attempts will be made to sample <br /> suspect ACMs in readily accessible areas. However, due to the nature of an asbestos assessment <br /> and the inability and impracticality of accessing some hidden locations, some areas/materials may <br /> Page 2 E <br /> mg <br />
