3130 Tchulahoma Warehouse

Asbestos Survey Report

The Memphis International Airport Facility located at 3130 Tchulahoma Road in Memphis, Shelby

County, Tennessee is preparing for renovations on the northern portion of the building to

accommodate a new tenant. The Memphis-Shelby County Airport Authority (Authority) prepared

a survey to identify asbestos containing materials (ACM) present within this space, as well as on

the roof.

Facility Description

The asbestos survey encompassed all potential ACM materials in the tenant’s space: drywall,

floor tile, floor tile mastic, cove base mastic, as well as multiple roofing materials (fabric

walkways, silver flashing, asphalt shingles, and black roofing). The building is shown in Figure 1

below:

Project Background

Asbestos has been a widely used component of building materials throughout history due to its

unique physical properties: poor heat and electrical conductor, fire resistance, and high tensile

strength and low cost. Unfortunately, asbestos also poses potentially serious health concerns for

people exposed to the material. Knowing where and how much ACM is located in a building

allows for proper managing of site activities and providing appropriate protection for building

occupants and workers involved in maintenance, renovation, or demolition of asbestos

containing materials.

This survey was conducted in general conformance with Asbestos Hazard Emergency Response

Act (AHERA) and ASTM Standard E2356-10. It included a walkthrough of the buildings to identify

suspect asbestos-containing materials, quantification of material amounts, collection of samples

from each homogenous area, and assessment per functional space.

Survey

The asbestos inspection was performed on June 8, 2017 by Lori Morris of the Authority, State of

Tennessee Certified Asbestos Inspector, Certification No. A-I-48800-56688. A copy of her

certification is included in Appendix 1.

During the inspection, Ms. Morris first conducted a survey of the 3130 Tchulahoma Warehouse

to determine the number of homogeneous areas and the number of samples that were needed

to be collected from each homogeneous area. Secondly, samples were collected from each

homogenous area for laboratory analysis. These samples were delivered to a NVLAP certified

laboratory for analysis by polarized light microscopy (PLM). ASTM/AHERA protocol was used in

the sampling and assessment of suspect ACM.

Asbestos Findings

All samples were transported to National Econ Labs, an NVLAP certified laboratory, for PLM

analysis on June 9, 2017. Results were received on June 14, 2017. Materials identified containing

greater than one percent (1%) asbestos are considered asbestos-containing. A copy of the

laboratory report is included in Appendix 2.

The laboratory analysis for samples collected as part of this survey found only 2 building materials

containing greater than 1% asbestos. Table 1 summarizes the homogenous areas and materials

sampled during this inspection as well as the results of the analysis.

Summary and Recommendation

All materials identified as asbestos-containing should be maintained in good condition to avoid

potential fiber release due to disturbance. In the event of renovation or demolition, the State of

Tennessee and NESHAP require that all friable ACM and non-friable ACM that could become

friable during renovation or demolition activities must be removed by a certified Asbestos

Abatement Contractor prior to disturbance.

In all instances, non-certified personnel should not disturb or attempt removal of any asbestos

containing materials. OSHA regulation 29 CFR 1926.1101 requires that a qualified, certified

Asbestos Abatement Contractor must be retained to perform abatement of ACM prior to

demolition or renovation activities at the Property. At no time are non-certified personnel

allowed to disturb or remove ACM.

It is recommended that any Asbestos Abatement Contractor retained to perform abatement

activities at the facility should be required to maintain proper engineering control measures prior

to and during the disturbance of all ACM to ensure protection of human health and safety for

personnel involved with this project. These control measures are also required for the protection

of the surrounding environment by preventing the possibility of contamination outside of the

abatement areas. Appropriate area air and personnel monitoring during the removal of these

materials must be conducted as per federal, state, and local regulations.

The following recommendations are in general conformance with the State of Tennessee, EPA,

NESHAP and OSHA requirements.

• Roofing fabric and black material on the roof that tested positive for asbestos are non-

friable, in good condition, and are classified as Category I materials. These materials can

be left in place during demolition of the building. If slicing or other methods that do not

sand, grind, cut or abrade the roofing material are used, the NESHAP does not apply,

regardless of the area of roof to be removed.

• If the roofing materials do become friable or damaged during demolition, NESHAP does

apply and proper authorities must be notified. Additionally, an asbestos abatement

contractor must be retained to abate this material.

According to the EPA, if a rotating blade roof cutter or equipment that similarly damages the

roofing material is used to remove Category I non-friable ACM, any roofing project that is 5,580

square feet or greater will create 160 square feet of RACM, is therefore subject to NESHAP.

Consequently, the proper authorities must be notified and the project must be performed by an

asbestos abatement contractor.

• In the event that suspect materials are identified during demolition or renovation,

additional testing should be performed to verify that these materials do not contain

asbestos.

Bulk Sample Test Report

Date Analyzed: June 13, 2017 Lab I.D. Number: 2017622

Client / Project Name: M&SC Airport Authority/ 3130 Tchulahoma Analyst: Netta Cooper

Comments: National Econ Corporation participates in the American Industrial Hygiene Association (AIHA) - Bulk Asbestos PAT Program (BAPAT). For all obviously heterogeneous

samples easily separated into sub-samples, and for layered samples, each component was analyzed separately. Disclaimer: Difficult samples such as floor tile, roofing material and samples

containing < 1% asbestos, may require additional analysis by TEM or SEM if No Asbestos Detected is reported. The above test report relates only to the items tested. This test report

relates only to the material analyzed. This sample was analyzed using the technique contained in 40 CFR 763, Subpart F, Appendix A (AHERA). Results from this report must not be

reproduced, except in full, with the approval of National Econ Corporation.
