Asbestos Survey Report Irerracon <br />Old Bethel Elementary School m Midland, North Carolina <br />November 29, 2010 �- Terracon Project No. 71107253 <br />3.+0 FIELD ACTIVITIES <br />The survey was conducted by Mr. Russell Harrings, Mr. William Reid and Mr, Christopher Kelley; <br />State of North Carolina accredited asbestos inspectors (no. 12222, 11977 and 12487). The <br />survey was conducted in general accordance with the sample collection protocols established in <br />EPA regulation 40 CFR 763, the Asbestos Hazard Emergency Response Act (AHERA). A <br />summary of survey activities is provided below. <br />3.1 Visual Assessment <br />Our survey activities began with visual observation of the interior and exterior of the structures to <br />identify homogeneous areas of suspect ACM. A homogeneous area consists of building materials <br />that appear similar throughout in terms of color, texture and date of application. Interior <br />assessment was conducted throughout visually accessible areas of the building. The exterior <br />survey included an assessment of the exterior walls and roofs. Building materials identified as <br />concrete, glass, wood, masonry, metal or rubber were not considered suspect ACM. <br />3.2 Physical Assessment <br />A physical assessment of each homogeneous area of suspect ACM was conducted to assess the <br />friability and condition of the materials. A friable material is defined by the EPA as a material <br />which can be crumbled, pulverized or reduced to powder by hand pressure when dry. Friability <br />was assessed by physically touching suspect materials. <br />3.3 Sample Collection <br />Based on results of the visual observation, bulk samples of suspect ACM were collected in <br />general accordance with AHERA sampling protocols. Random samples of suspect materials <br />were collected in each homogeneous area (HA), Samples were placed in sealable containers <br />and labeled with unique sample numbers using an indelible marker. <br />Sixty (60) bulk samples were collected from eighteen (18) HA's in Building A. <br />Twenty -nine (29) bulk samples were collected from eight (8) HA's in Building B. <br />Fifty -eight (58) bulk samples were collected from sixteen (16) HA's in Building C. <br />Twenty -five (25) bulk samples were collected from eight (8) HA in Building D. <br />Forty -two (42) bulk samples were collected from fourteen (14) HA's in Building E. <br />Fifteen (15) bulk samples were collected from six (6) HA's from the exterior outbuildings. <br />Reliable a Responsive ■ Convenient ■ Innovative <br />3 <br />Attachment number 4 <br />G -6 Page 283 <br />
