4 EXECUTIVE SUMMARY United Consulting has completed limited sampling for Asbestos Containing Materials (ACM) on the Plaza Latina property in Norcross, Gwinnett County, Georgia. This property is hereafter referred to in this report as the Project Site. The results from this investigation are briefly summarized below. The text of the report should be reviewed for the basis and a discussion of these items.. The Project Site contained one single story brick structure that was finished on the interior with drywall system components, ceiling tiles, floor tiles, and other materials.. A total of 39 samples were collected from the Project Site structure of suspect asbestos containing materials (SACM) as part of Stage Two of this assessment. United Consulting previously collected 3 samples of SACM from the Project Site as part of Stage One. Based on the results from Stage One and Stage Two, United Consulting recommends considering all black floor mastic, all roof tar, and all exterior window caulk at the Project Site as ACM. 3. In the event that inaccessible, SACM are encountered within previously inaccessible building areas (wall cavities, columns, inaccessible roof areas, etc.) at the time of demolition, United Consulting should be contacted and proper samples of the suspect materials should be collected and submitted for testing, prior to continuing demolition activities which could disturb these materials and potentially result in an asbestos fiber release. 4. The National Emissions Standard for Hazardous Air Pollutants (NESHAP) requires the removal of asbestos-containing materials prior to activities, which would disturb them. In the event that ACM is encountered, United Consulting recommends that the asbestoscontaining materials be removed, by a qualified asbestos abatement contractor, using State of Georgia accredited personnel, in accordance with applicable federal, state and local regulations governing the removal of asbestos-containing material. 5. A properly prepared Ten Day Notification must be forwarded to the Georgia Department of Natural Resources Environmental Protection Division, by the building owner or renovation contractor, prior to the start of any building demolition/renovation activities. 6. Please note the Occupational Safety and Health Administration (OSHA) regulations require that workers be protected from exposure to asbestos via proper engineering controls and appropriate levels of personal protective equipment.

5 INTRODUCTION United Consulting was retained by City of Norcross to perform sampling for Asbestos Containing Materials (ACM). The purpose of this survey was to collect and test representative samples of common building materials for the presence of asbestos fibers. Photographs of the Project Site structure are included in Appendix B. SCOPE The scope of this assessment was outlined in United Consulting s December 5, 06 proposal, executed by the client on December 8, 06.. Conducting sampling of identified suspect asbestos containing materials (SACM) and submitting samples to an independent laboratory for analysis of asbestos;. Preparing this report of the sampling activities and findings. DESCRIPTION OF FACILITIES The Project Site contained one single story brick structure that was finished on the interior with drywall system components, ceiling tiles, floor tiles, and other materials. The brick structure had second story mezzanine level areas used for storage. Overview BULK SAMPLE COLLECTION Bulk sampling was performed in substantial conformance with the United States Environmental Protection Agency s (EPA's), "Guidance for Controlling Asbestos-Containing Materials in Buildings" (EPA 560/ , 985). Bulk sampling was performed at the Project Site on January 9, 07 by Mr. Tyler Kelly and Mr. Michael Abernathy. Mr. Kelly and Mr. Abernathy are accredited Asbestos Inspectors in accordance with the Asbestos Hazard Emergency Response Act (AHERA), Inspector Certificate Numbers 488 and 5876, respectively. Their certifications and that of the laboratory used for this investigation are reproduced in Appendix C. Sample Locations/Limiting Conditions Sample locations were randomly chosen in the field, based on the identification of suspect asbestos-containing material (SACM). A distributed sampling plan based on a randomized sampling scheme was not used for this sampling program. This survey was being conducted to evaluate the property for the presence of asbestos prior to possible building demolition. The SACM sampling locations are shown in Figure. Page 4 of 7

6 Bulk samples were collected from typical suspect materials such as drywall, roof shingles, vinyl floor tile, and other suspect materials. Bulk samples were not collected of non-suspect materials such as carpets, drapes, wood, fiberglass insulation or ceramic tiles. Destructive sampling techniques were employed at the Project Site building, as it was vacant. We did not have the necessary tools to assess what was in between sheet metal layers on the roof. This represents a limiting condition. Procedure Samples were collected by wetting the material to be sampled, by extracting a representative section of the suspect material and by placing the material in a sample container. Each sample was assigned a unique sample number and delivered to an independent laboratory (Analytical Environmental Services, Inc.) for analysis. Chain-of-Custody was documented and retained onfile. The laboratory results are attached in Appendix D. Bulk Sample Analysis The bulk samples were tested for detectable concentrations of asbestos (greater than one percent asbestos) utilizing Polarized PLM and dispersion staining techniques. The testing method used was the Interim Method for the Determination of Asbestos in Bulk Insulation Samples (EPA 600/M4-800, as amended). Materials containing one percent or more asbestos are considered ACM and are regulated. Bulk sample testing was performed by Analytical Environmental Services, Inc., a successful participant in the National Voluntary Laboratory Accreditation Program (NVLAP), certificate number General BULK SAMPLE RESULTS United Consulting collected 39 bulk samples of SACM from the Project Site structure during this sampling event. The items included drywall system components, floor tiles, caulk, drywall system components, roofing systems, and other materials. The survey results discussed below have been compiled by material location and material type (e.g., floor tile, caulk, etc.). Photocopies of the Laboratory Results are included in Appendix D. Sample locations are shown in Figure. A summary of the bulk sample results is presented in Table in Appendix A. Page 5 of 7

7 ACM DATA EVALUATION/ASSESSMENT Regulated concentrations of asbestos were detected in one of the roof tar samples collected from the Project Site. Despite regulated concentrations of asbestos not being detected in the remaining roof samples collected, United Consulting recommends assuming all roof tar as ACM or additional samples can be collected and tested to possibly delineate areas that are ACM. Based on the results of Stage One and Stage Two of this assessment, United Consulting recommends considering all black floor mastic, all roof tar, and all exterior window caulk at the Project Site as ACM. SACM sampling locations are shown on Figure. In the event that inaccessible, SACM are encountered within previously inaccessible building areas (wall cavities, columns, inaccessible roof areas, etc.) at the time of demolition, United Consulting should be contacted and proper samples of the suspect materials should be collected and submitted for testing, prior to continuing demolition activities which could disturb these materials and potentially result in an asbestos fiber release. The National Emissions Standard for Hazardous Air Pollutants (NESHAP) requires the removal of asbestos-containing materials prior to activities, which would disturb them. In the event that ACM is encountered, United Consulting recommends that the asbestos-containing materials be removed, by a qualified asbestos abatement contractor, using State of Georgia accredited personnel, in accordance with applicable federal, state and local regulations governing the removal of asbestos-containing material. A properly prepared Ten Day Notification must be forwarded to the Georgia Department of Natural Resources Environmental Protection Division, by the building owner or renovation contractor, prior to the start of any building demolition/renovation activities. Please note the Occupational Safety and Health Administration (OSHA) regulations require that workers be protected from exposure to asbestos via proper engineering controls and appropriate levels of personal protective equipment. LIMITATIONS The conclusions presented in this Limited Asbestos Survey report are based on the laboratory results and condition of the materials identified. Asbestos concentrations will vary between sample locations. Our assessment of the materials at the Project Site is a professional opinion arrived at through the method and procedures accepted by and standard to the industry. No other warranty or guarantee is expressed or implied. Preparation of abatement design bid documents or scopes of work for abatement, will require additional sampling and definition of the extent of the materials. United Consulting shall not be held responsible for errors, miscalculations, assumptions, misinterpretations or other problems Page 6 of 7
