Asbestos survey Report Nerracon Old Bethel Elementary School A Midland, North Carolina November 29, 2010 a Terracon Project No. 71107253 3.4 Sample Analysis Sulk samples were submitted under chain of custody to Pinnacle Environmental Consultants, Inc. (Pinnacle) of Hurricane, West Virginia for analysis by polarized light microscopy per EPA. methodology EPA16001R- 931116. The percentage of asbestos, where applicable, was determined by microscopic visual estimation or point counting. Pinnacle is accredited under the National Voluntary Laboratory Accreditation Program (NVLAP Accreditation No. 200718 -0). The laboratory was instructed to analyze samples from each homogeneous area until the first sample containing asbestos was identified. 4.0 REGULATORY OVERVIEW The asbestos NESHAP (40 CFR Part 61, Subpart M) regulates asbestos fiber emissions and asbestos waste disposal practices. It also requires the identification and classification of existing building materials prior to demolition or renovation activity, Under NESHAP, asbestos- containing building materials are classified as either friable, Category I non - friable or Category 11 non - friable ACM. Friable materials are those that, when dry, may be crumbled, pulverized or reduced to powder by hand pressure. Category I non - friable ACM includes packings, gaskets, resilient floor coverings and asphalt roofing products containing more than 1% asbestos. Category 11 non - friable ACM are any materials other than Category I materials that contain more than 1% asbestos. Friable ACM, Category I and Category II non - friable ACM which is in poor condition and has become friable or which will be subjected to drilling, sanding, grinding, cutting or abrading and which could be crushed or pulverized during anticipated renovation or demolition activities are considered regulated ACM (RACM). In the state of North Carolina, the HHCU regulates asbestos activities. The NC HHCU requires that any asbestos - related activity conducted in a public building be performed by personnel licensed by NC HHCU. RACM must be removed prior to renovation or demolition activities which will disturb the materials. The owner or operator must provide the NC HHCU with written notification of planned removal activities at least 10 working days prior to the commencement of asbestos abatement activities. Removal of RACM must be conducted by a State of North Carolina licensed asbestos abatement contractor. In addition, third party air monitoring must be performed following the abatement. The OSHA Asbestos standard for construction (29 CFR 1926.1101) regulates workplace exposure to asbestos. The OSHA standard requires that employee exposure to airborne asbestos fibers be maintained below 0.1 asbestos fibers per cubic centimeter of air (0.1 ficc). The OSHA standard classifies construction and maintenance activities which could disturb ACM, and Reliable r Responsive ■ Convenient n Innovative 4 Attachment number 4 G -6 Page 284
