TANG Buildings M110 and M111, Alcoa, Tennessee November 30, 2017

SUMMARY OF SERVICES

Our asbestos survey services outlined below are intended to supplement information contained in the TANG AMP. Prior to our surveys, we conducted a review the TANG AMP data and compared it to our observations of the current building conditions. The TANG AMP reviewed was dated September 2014. The asbestos surveys of buildings M110 and M111 were conducted by Mr. Eduardo Padron, a State of Tennessee Accredited Asbestos Management

Planner, on September 9, 2017.

The survey approach included a visual assessment of representative materials to locate, as far as practicable, suspect ACM. Suspect materials were divided into Homogeneous Areas (HA), building materials which were determined by our consultant to be homogeneous based on their color, texture, and age. A representative number of samples were collected from each HA.

The bulk material samples collected were placed in sealable plastic bags and sent under chain-of-custody protocol to Arrowhead Technologies, LLC, located in Clearwater, Florida for analysis.

Material identification was performed using Polarized Light Microscopy with Dispersion Staining

(PLM/DS) in accordance with the Environmental Protection Agency “Method for the Determination of Asbestos in Bulk Building Materials” (EPA/600/R-93/116). Laboratory analysis summary reports and the Chains of Custody are included in Appendix A. Arrowhead Technologies participates in the National Voluntary Laboratory Accreditation Program (NVLAP) as administered by the National Institute of Standards and Technology (NIST). PC&D is a State of Tennessee

Accredited Asbestos Firm. Accreditation certificates for Mr. Padron, Arrowhead Technologies, LLC, and PC&D are included in Appendix B.

Asbestos Survey of Building M110

During our survey of building M110 we identified nine (9) suspect HAs and collected and submitted a total of eighteen (18) bulk samples for laboratory analysis. Based on the laboratory data, asbestos-containing flooring was identified in the bulk samples collected and analyzed from building M110. The following table summarizes our sampling.

Asbestos Survey Update of Building M111

Our review of the AMP found that the asbestos survey of building M111 identified several areas of ceiling and flooring finishes in the NW office and shop areas, which were incorrectly assumed to be present in the SW and SE offices. In addition, the AMP showed thermal insulation system materials that were identified as ACM and non-ACM; these were not re-sampled during our survey. During our survey we identified ten (10) suspect HAs and collected and submitted a total of twenty (20) bulk samples for laboratory analysis as described above. Based on the laboratory data, additional asbestos-containing flooring was identified in the bulk samples collected and analyzed from building M111. The following table summarizes our sampling.

Roof Asbestos Survey of Building M111

The roofs on building M111 were observed to be standing seam metal roofs and accessed for sampling from the ground by means of a 60’ articulated lift. The roof decking had been observed to be cementitious panels, which were accessible in the tool room of the building. Four (4) suspect HAs were identified during the roof survey and a total of eight (8) bulk samples were collected and submitted for laboratory analysis as described above. Based on the laboratory data, no asbestos-containing materials were found in the bulk samples collected and analyzed from the roofing materials of building M111.

TANG Buildings M110 and M111, Alcoa, Tennessee November 30, 2017

Our consultants accessed the roof above the SW offices and shops (Tire Shop) and cut a section of the metal roof using a metal saw blade. Observations though the opening revealed insulation on the cementitious deck (HA 9) consisting of expanded polystyrene foam sheets (Styrofoam).

See picture below:

TANG Buildings M110 and M111, Alcoa, Tennessee November 30, 2017

Additional sampling locations were located near the SW corner of the upper (hangar) roof. Two access openings were cut in the upper roof to sample for possible roofing materials under the metal roof panels. Observations though the openings revealed fiberglass insulation bats adhered to a plastic vapor barrier located on top of the the cementitious deck. The deck was covered with a bituminous layer (non-ACM, HA 10). See picture below:

The roof openings were repaired with aluminum flashing fastened down with self-tapping screws and sealed with roofing cement. These repairs are temporary in nature and not guaranteed or

TANG Buildings M110 and M111, Alcoa, Tennessee November 30, 2017 warrantied to prevent water intrusion into the building. A qualified roofing contractor should be retained by others to conduct final repairs. A picture of the typical repaired location is shown below:

RECOMMENDATIONS

Asbestos-containing materials (ACM) were identified in our survey of buildings M110 and M111, beyond those identified in the TANG AMP. Therefore, we recommend the following:

• The asbestos-containing containing flooring materials identified in the surveys should be properly managed in-place until their removal is forced by demolition or planned renovation of the building, in accordance with guidelines established in the TANG AMP.

These flooring materials are considered Category I non-friable materials. The flooring materials found during our survey to contain asbestos in buildings M110 and M111 are in good condition and effectively encapsulated by a layer of non-asbestos containing flooring.

• Due to the forces that may act on these materials during demolition of the building and removal of the floor slabs, these materials should be removed prior to demolition of the structure or renovations that may disturb them.

We understand that these buildings may be scheduled for renovation or demolition. The current

EPA regulation for the removal of asbestos in buildings i.e., the National Emission Standard for

Hazardous Air Pollutants (NESHAP, 40 CFR 61, Subpart M), requires that regulated asbestos-containing materials (RACM) be properly removed prior to performing renovation and demolition activities which would disturb them. RACM is generally defined as materials which contain greater than one percent asbestos and are one of the following:

1. Friable materials

2. Non-friable materials which have become friable.

3. Category I non-friable materials which have been sanded, ground, cut, or abraded.

4. Category II non-friable materials which are expected to become friable due to the forces expected to act on them during demolition.

A friable asbestos-containing material is defined as any material that contains more than one percent asbestos by weight that, when dry, can be crumbled, pulverized, or reduced to powder by hand pressure. The EPA categorizes non-friable materials into two categories:

1. Category I non-friable materials are specifically defined as resilient floor coverings;

asphalt-based bituminous roofing materials; packings; construction mastics; and gaskets.

2. Category II non-friable materials include all other non-friable materials such as asbestos cement products; vibration dampeners; caulking; putties; etc.

TANG Buildings M110 and M111, Alcoa, Tennessee November 30, 2017

If other suspect materials that are not referenced in this report or in the AMP are discovered or identified during renovation or demolition activities, PC&D recommends that the materials be sampled and analyzed to confirm the absence or presence of asbestos prior to disturbance of these materials.

Please note that prior to renovation or demolition of these buildings, a 10-Day Notification Form must be submitted to the Tennessee Department of Environment & Conservation. A copy of this report as well as pertinent portions of the AMP should be attached to the notification to provide a complete submission.

SCOPE OF THIS REPORT

These samples were obtained as a part of a building survey; this report is only intended to be used as a part of the survey report issued by the surveyor. This report explains the laboratory analysis and results. The surveyor's report explains the sampling protocol used, when the samples were obtained, the location(s) of the samples, where the materials were observed in the building, quantities of materials observed, condition of the materials and the extent of his/her survey. Sample locations and material descriptions are given by the surveyor on the chain of custody but included here (possibly abbreviated) only as a convenience for the reader.

This report may not be reproduced without written permission of Arrowhead and must be reproduced in full.

STATEMENT OF LABORATORY ACCREDITATION

The samples were analyzed in general accordance with the procedures outlined in the Method for the Determination of

Asbestos in Bulk Building Materials, EPA/600/R-93/116, and the Interim Method for the Determination of Asbestos in Bulk

Insulation Samples, EPA 600/M4-82-020. The results of each bulk sample relate only to the material tested and the results shall not be used to claim product endorsement by NVLAP or any agency of the U.S. Government.

Floor tile and other resinously bound materials, when analyzed by the EPA method, may yield false negative results because of limitations in separating closely bound fibers and in detecting fibers of small length and diameter. When a definitive result is required, Arrowhead recommends utilizing alternative methods of identification, including Transmission Electron Microscopy.

Specific questions concerning bulk sample results shall be directed to the Laboratory Director.

SCOPE OF THIS REPORT

These samples were obtained as a part of a building survey; this report is only intended to be used as a part of the survey report issued by the surveyor. This report explains the laboratory analysis and results. The surveyor's report explains the sampling protocol used, when the samples were obtained, the location(s) of the samples, where the materials were observed in the building, quantities of materials observed, condition of the materials and the extent of his/her survey. Sample locations and material descriptions are given by the surveyor on the chain of custody but included here (possibly abbreviated) only as a convenience for the reader.

This report may not be reproduced without written permission of Arrowhead and must be reproduced in full.

STATEMENT OF LABORATORY ACCREDITATION

The samples were analyzed in general accordance with the procedures outlined in the Method for the Determination of

Asbestos in Bulk Building Materials, EPA/600/R-93/116, and the Interim Method for the Determination of Asbestos in Bulk

Insulation Samples, EPA 600/M4-82-020. The results of each bulk sample relate only to the material tested and the results shall not be used to claim product endorsement by NVLAP or any agency of the U.S. Government.

Floor tile and other resinously bound materials, when analyzed by the EPA method, may yield false negative results because of limitations in separating closely bound fibers and in detecting fibers of small length and diameter. When a definitive result is required, Arrowhead recommends utilizing alternative methods of identification, including Transmission Electron Microscopy.

Specific questions concerning bulk sample results shall be directed to the Laboratory Director.
