GENERAL ASBESTOS SURVEY OF

Building 4702, George C. Marshall Space Flight Center, Marshall Space Flight Center, Alabama

1. Introduction

In accordance with GSE Task Order No.GSE-013 dated April 21, 2008, Great Southern Engineering, Inc. (GSE) has performed an asbestos survey of Building 4702 located at George C.

Marshall Space Flight Center, Marshall Space Flight Center, Alabama. The 8,388 square feet building was identified to have been originally constructed in 1955. A total of 35 samples were collected from the building.

The objective of the Asbestos Survey is to determine the location and quantity of asbestos-containing materials at the Property building.

GSE’s Scope of Work included:

Visual inspection and identification of suspect asbestos-containing materials (ACMs) in the Property building and collected a representative number of samples for analysis.

As part of this asbestos survey, GSE personnel collected samples of all suspect friable and suspect damaged non-friable building materials at the Property. The remaining suspect non-friable materials were not be sampled as part of this asbestos survey

Estimated quantities and locations of ACM.

Assessed the condition of the ACM identified.

Assigned a hazard rating to each type of ACM.

This report has been prepared for the use of George C. Marshall Space Flight Center. Our investigation was performed using the degree of care and skill ordinarily exercised under similar circumstances by professional consultants practicing in this or similar localities. No other warranty or guarantee, expressed or implied, is made as to the conclusions included in this report.

Task Order GSE 013 Page 2 of 26

Building 4702, George C. Marshall Space Flight Center, Marshall Space Flight Center, Alabama

The GSE, Inc. did not perform destructive sampling procedures at the site; therefore, regardless of the thoroughness of this survey, it is possible that suspected asbestos-containing materials (ACMs) might exist in the building beneath the floors, behind walls, within pipe chases, or in other inaccessible locations. If, during renovation or demolition activities, materials not addressed in this survey are discovered, these materials should be sampled and analyzed for asbestos content prior to disturbance.

2.1. Suspect ACMs

The following information is included for informational purposes:

A. The following suspect asbestos-containing materials were not sampled as part of this scope of work:

Suspect fibrous electrical cable covering (danger of electrocution) were not sampled.

These materials are not subject to regulation under NESHAP for demolition and renovation as long as they are in good condition and are not subject to sanding, grinding, cutting, or abrading.

Since ordinary demolition activities do not include sanding, grinding, cutting, and abrading, these materials may remain in place during building demolition, as long as they remain in good condition and are not friable.

If the material is in poor condition and is friable at the time of demolition or renovation, or if it will be subjected to sanding, grinding, cutting, or abrading, it should first be removed by a licensed asbestos removal contractor and disposed of as asbestos-containing waste.

When removing asphalt-roofing products, the material should be removed using a method that does not subject the material to sanding, cutting, grinding, or abrading (hand tools).

Asbestos-containing roofing may be disposed of as construction debris.

2.2. Recommendations

The following additional actions are recommended:

No further actions are recommended at this time.

3. Survey Scope

This survey was conducted for the purpose of identifying asbestos-containing materials (ACM) throughout the building and to conduct a hazard assessment on existing ACM. The survey was non-destructive in nature and limited only to those areas that were readily accessible.

Specific areas to which access was limited by occupant request, unavailability of keys, or by site conditions included the following:

Behind the walls

Beneath the floors

Any suspect ACM not sampled as part of the assessment and if any additional suspect materials were to be identified behind walls and beneath the floors should be sampled prior to repair, renovation, or demolition activities.

Task Order GSE 013 Page 6 of 26

Building 4702, George C. Marshall Space Flight Center, Marshall Space Flight Center, Alabama

4. Limitations

GSE did not attempt to disassemble mechanical equipment, open pipe chases or assess materials within wall voids. Regardless of the thoroughness of a survey, the possibility exists that some areas containing asbestos were not identified, inaccessible or different from those at specific locations. The findings and opinions presented are relative to the dates of our site work and should not be relied upon to represent conditions at substantially later dates due to changes in the condition ACM may change over time, renovations and repairs.

This report is for the exclusive use of the client and its agents and use by any unauthorized parties in whole or in part, except as directed by legal jurisdiction, is at the sole risk of the user.

If this assessment includes reliance on work products and/or documents prepared by others, GSE has no responsibility for the accuracy of information contained therein.

Although this assessment has attempted to identify the presence or absence of ACM, potential sources of ACM may have escaped detection due to: (1) the scope of this assessment, (2) the inaccuracy of records, interviews, work products or documents made available to GSE for this report, (3) the presence of undetected or unreported renovations and repairs, (4) inaccessible areas, and/or (5) deliberate concealment of detrimental information.

Estimates presented in this report are based upon observations during the survey and owner-provided information. These reasonable estimates may be affected by unanticipated conditions potentially present in inaccessible or un-surveyed areas. GSE does not warrant or guarantee the quantity estimates. The use of such estimates shall be at the user's own risk and shall constitute a release and agreement to defend and indemnify GSE from and against any liability. If questions arise during the planning for renovation, demolition, or other construction activities, GSE should be notified to permit review of the data and present recommendations.

Interior of the following rooms were inaccessible during our Asbestos Survey on May 13 and September 4, 2008: None.

5. Survey and Sample Collection Procedure

Based on United States Environmental Protection Agency (USEPA) guidance documents, GSE considered all material applications identified during the visual assessment were suspect ACM and sampled as described below.

Bulk samples were collected of any materials, which were suspected of containing asbestos with the exception of fire doors. Fire doors were not sampled because the damage caused by sampling would render these materials friable and may also void the fire rating. Since these materials were not sampled, they should be assumed to be asbestos containing, unless sampled and proven otherwise. Sampling of these assumed ACMs should be performed prior to any renovation or other activity that may cause a material disturbance.

Samples of the remaining suspect ACM were taken in accordance with USEPA recommendations.

The number and location of samples collected was based on the type of material, the manner of application, and the homogeneity of the ACM (similarity of color, texture, and type). Each sample was collected and placed into an individual sample container. The sample location was noted on the field survey form and assigned an individual identification number. This number was affixed to the sample container as the sample was collected. The survey form was also used to note the material type and general condition of the material. During the inspection, each suspect material's accessibility, location, and friability were recorded. This information was used to assess the potential hazard of the ACM and to prioritize response action recommendations.

The USEPA defines asbestos-containing materials (ACM) as those that contain greater than one percent asbestos. Friable materials are defined as those that can be crumbled or reduced to powder by hand pressure.

GSE utilized the “positive-stop” method of sample analysis. In this method, analysis is stopped on a group of samples once the first positive (e.g., greater than 1% asbestos) sample is analyzed.

According to the USEPA, if one sample of a homogenous material is identified to be asbestos containing, the entire material must be considered asbestos containing. By using the positive-stop method, GSE reduces the Client’s laboratory analysis cost by not analyzing the additional samples.

Samples collected were carried and submitted under Chain-of-Custody to Steve Moody Micro Services LLC, Farmers Branch, Texas for analysis of asbestos using USEPA Method 40 CFR, Chapter 1, Part 763, Subpart F, Appendix A, also known as Polarized Light Microscopy (PLM).

6. Previous Survey / Plans Review

GSE was not provided with any previously conducted asbestos surveys of the Property. As-built/renovation-site plans and construction drawings were reviewed at the Facilities Department Drawing Room. Review of these documents did not identify building material specifications requiring the use of ACM. However, this does not preclude or prevent the potential use of ACM.

Building 4702, George C. Marshall Space Flight Center, Marshall Space Flight Center, Alabama

7. Suspect ACM Materials Not Sampled

During the course of the property visit, GSE performed a preliminary review of interior, accessible areas of the subject building for the presence of suspect asbestos-containing materials (ACMs). This asbestos survey was conducted for overview purposes only; additional suspect materials may exist in concealed locations (behind walls and above ceilings, beneath the floors, within machinery, etc.). Also, not all suspect materials may have been sampled due to the condition or the location of the suspect materials. Destructive sampling of suspect ACMs was not performed. GSE will not be responsible for damaging materials or causing the materials to become friable. The USEPA defines asbestos-containing material as material containing greater than one percent asbestos. This review was not a pre-demolition/renovation survey or for regulatory submittal purposes.

Suspect and/or presumed ACMs were observed within the subject building during the property visit. These suspect and/or presumed ACMs that were not sampled as part of this asbestos survey are listed in the following table.
