(Terracon) conducted an asbestos in soil survey of the above referenced site in Davidson, North Carolina. The survey was conducted between July 27-29, 2015 and September 9-10, 2015 by a North Carolina accredited asbestos inspector in general accordance with Terracon Proposal No. P71150239 dated July 30, 2015 and supplemental proposal numbers P71150239r1a and P71150239r2 dated August 20, 2015 and September 25, 2015 and asbestos sampling necessary to characterize the extent of asbestos contamination present at the Davidson Depot site. We understand this asbestos survey was requested due to the planned development of the above referenced site to address potential asbestos soil contamination. 1.1 Reliance This report is for the exclusive use of Miller-Valentine Residential Development LLC and Davidson Depot LLC for the project being discussed. Reliance by any other party on this report is prohibited without written authorization of Terracon and Miller-Valentine Residential Development LLC and Davidson Depot LLC. Reliance on this report by Miller-Valentine Residential Development LLC and Davidson Depot LLC and all authorized parties will be subject to the terms, conditions and limitations stated in the proposal, this report and Terracon’s Agreement for Services. The limitations of liability defined in Terracon’s Agreement for Services is the aggregate limit of Terracon’s liability to Miller-Valentine Residential Development LLC and Davidson Depot LLC. 2.0 LAND DESCRIPTION This site is located at 301 Depot Street in Davidson, North Carolina. This property includes the existing buildings, parking areas, abandoned building foundations, and a capped landfill area previous reported to contain asbestos debris. Manicured grass and asphalt parking and drive way areas also are located on the site. The site is bound by Depot Street, Sloan Street and Eden Street with a railroad right of way on the east side of the property. The site generally slopes from a high of 814 feet on the eastern portion of the site to a low of 780 feet on the western portion of the site. The landfill area is an approximate elevation of 800 feet. Asbestos in Soil Survey Report Davidson Depot ■ Davidson, North Carolina June 17, 2016 ■ Terracon Project No. 71155040 Responsive ■Resourceful ■Reliable 2 3.0 FIELD ACTIVITIES The survey was conducted by North Carolina accredited asbestos inspector Alex Manzanarez (Accreditation No. 12617). The survey was conducted in general accordance with the sample collection protocols established in USEPA 40 CFR Part 763 Subpart E 763.86, AHERA and industry practices. A summary of survey activities is provided below. 3.1 Visual Assessment Survey activities were initiated with visual observation of the property to identify areas suspected of having deposits of asbestos debris. Terracon picked different locations to test the soil inside of the area that will be developed. Areas currently planned for significant undercut by the current development plan were specifically targeted. Terracon also chose locations that were not expected to have deposits of asbestos debris for comparison. 3.2 Physical Assessment A physical assessment of each sample location of suspect asbestos-containing materials (ACM) was conducted to assess the friability and condition of the materials. A friable material is defined by the USEPA as a material which can be crumbled, pulverized or reduced to powder by hand pressure when dry. Friability was assessed by physically touching suspect materials. 3.3 Sample Collection Based on results of the visual observation of the soil borings, bulk soil samples of suspect ACM were collected in general accordance with USEPA AHERA and industry accepted sampling protocols. Please refer to the attached drawing (A-2A) in Appendix C for sample locations. The selection of sample locations and frequency of sampling were based on Terracon’s observations and the assumption that like materials in the same area are homogeneous in content. Terracon collected forty-four (44) soil samples from nineteen (19) areas of suspect ACM on the site. A summary of suspect ACM samples collected during the survey is included as Appendix B. 3.4 Sample Analysis Soil samples were submitted under chain of custody to EMSL Analytical, Inc. (EMSL) of Cinnaminson, New Jersey for analysis by ASTM D7521: Standard Test Method for the Asbestos in Soil Survey Report Davidson Depot ■ Davidson, North Carolina June 17, 2016 ■ Terracon Project No. 71155040 Responsive ■Resourceful ■Reliable 3 Determination of Asbestos in Soil. The percentage of asbestos, where applicable, was determined by weighted asbestos concentration. 4.0 REGULATORY OVERVIEW The asbestos NESHAP (40 CFR Part 61, Subpart M) regulates asbestos fiber emissions and asbestos waste disposal practices. The asbestos NESHAP regulation also requires the identification and classification of existing ACM according to friability prior to demolition or renovation activity. Friable ACM is a material containing more than 1% asbestos that, when dry, can be crumbled, pulverized or reduced to powder by hand pressure. All friable ACM is considered regulated asbestos containing material (RACM). The asbestos NESHAP regulation classifies ACM as either RACM, Category I non-friable ACM or Category II non-friable ACM. RACM includes all friable ACM, along with Category I and Category II non-friable ACM that has become friable, will be or has been subjected to sanding, grinding, cutting or abrading, or ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder in the course of renovation or demolition activity. Category I non-friable ACM are exclusively asbestos-containing packings, gaskets, resilient floor coverings, resilient floor covering mastics and asphalt roofing products that contain more than 1% asbestos. Category II non-friable ACM are all other non-friable materials other than Category I non-friable ACM that contain more than 1% asbestos. Category II non-friable ACM generally includes but is not limited to cementitious material such as: cement pipes, cement siding, cement panels, glazing, mortar and grouts. 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 f/cc). The OSHA standard classifies construction and maintenance activities which could disturb ACM, and specifies work practices and precautions which employers must follow when engaging in each class of regulated work. States which administer their own federally-approved state OSHA programs may require additional precautions. In the state of North Carolina, the Health Hazards Control Unit (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. Asbestos in Soil Survey Report Davidson Depot ■ Davidson, North Carolina June 17, 2016 ■ Terracon Project No. 71155040 Responsive ■Resourceful ■Reliable 4 5.0 FINDINGS Asbestos was identified in soil samples of varying depths throughout the site. Please refer to Appendix A for specific borings, sample depths and sample locations. Boring logs are included in Appendix D. Based on the results of the asbestos sampling at this site, Terracon recommends that soil contaminated with asbestos, if excavated, be removed and disposed as an asbestos-containing material. Excavation and grading on the site should be performed by an experienced asbestos abatement contractor using North Carolina accredited asbestos workers and supervisors. Specific technical work procedures and an asbestos monitoring plan should be developed for this work. Terracon also recommends that once the asbestos soil removal is complete, a geotextile liner could be installed with a minimum 12” cap of clean soil. The geotextile liner would serve as a demarcation point between clean and potentially asbestos-contaminated soil. 6.0 LIMITATIONS/GENERAL COMMENTS This asbestos soil survey was conducted in a manner consistent with the level of care and skill ordinarily exercised by members of the profession currently practicing under similar conditions in the same locale.
