EMSL maintains liability limited to cost of analysis . Interpretation and use of test results are the responsibility of the client. This report relates only to the samples reported above, and may not be reproduced, except in full, without written approval by EMSL. EMSL bears no responsibility for sample collection activities or analytical method limitations . The report reflects the samples as received.

Results are generated from the field sampling data (sampling volumes and areas, locations, etc.) provided by the client on the Chain of Custody. Samples are within quality control criteria and met method specifications unless otherwise noted. The above analyses were performed in general compliance with Appendix E to Subpart E of 40 CFR (previously EPA 600/M4-82-020 “Interim Method”) but augmented with procedures outlined in the 1993 (”final”) version of the method. This report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST or any agency of the federal government. Non- friable organically bound materials present a problem matrix and therefore EMSL recommends gravimetric reduction prior to analysis . Unless requested by the client, building materials manufactured with multiple layers (i.e. linoleum, wallboard, etc.) are reported as a single sample. Estimation of uncertainty is available on request.

PROJECT SUMMARY

PROPERTY ADDRESS: Elevator Building – Wind Cave National Park

CLIENT: National Park Service – Wind Cave National Park

CONSULTANT: Prairie Environmental Consulting, LLC PO Box 1266 Sioux Falls, SD 57101

AHERA BUILDING INSPECTOR: Jason Biggins, SD Cert #8347

INSPECTION AND SAMPLING DATE: April 6, 2021

REPORT DATE: April 12, 2021

Executive Summary

Jason Biggins of Prairie Environmental Consulting, LLC was contacted by Joshua Kreilaus with NPS – Wind Cave regarding an asbestos inspection at the Elevator Buidling, located near the Visitor’s Center in Wind Cave National Park.

An asbestos inspection will help the determine if any materials require special consideration or should be removed prior to renovation of this property.

On April 6, 2021, Jason arrived on-site at 3:00pm to conduct the inspection.

Jason collected five asbestos bulk samples of materials within the building.

The analytical results indicate that the following building materials DO contain asbestos:

o Window Glaze – 1st fl E Window (S side) – 4% Chrysotile

The analytical results indicate that the following building materials do NOT contain asbestos:

o Window Glazing – Other 1st floor windows o Concrete o Sheet Flooring o 12x12 Floor Tile + Adhesive o Wall Tile + Adhesive

The following building materials were NOT sampled and are presumed to be asbestos-containing.

o None

Asbestos Bulk Sampling Methodology

Asbestos bulk samples were collected and placed in sample bags for laboratory analysis. This sampling was performed to identify asbestos in specific suspect asbestos-containing materials (ACM). The samples were submitted for standard turnaround time analysis via polarized light microscopy (PLM).

The PLM method is the most commonly used method to analyze the building materials for the presence of asbestos. The PLM method is in accordance with the EPA Interim Method of the Determination of Asbestos in Bulk Samples (EPA, July 1993). This method utilizes the optical properties of minerals to identify the selected constituent. The use of this method enables identification of the type and the percentage of asbestos in a sample.

The detection limit of the PLM method for asbestos identification is approximately one percent (1%) asbestos. PEC recommends Transmission Electron Microscopy (TEM) or Point Counting analysis for asbestos samples with trace, or less than one percent (<1%) when analyzed via PLM.

In some cases, samples collected from an apparently homogeneous material and yielding mixed results may, in face, have been taken from different homogeneous materials displaying similar visual characteristics buy composed of different constituents. Although materials may appear to be homogeneous, different manufacturers may have produced them in different batches. Materials, which appear to be homogeneous buy yield mixed results, are typically assumed, in accordance with AHERA procedures, to be asbestos containing in all areas where the materials are located.

PLM Asbestos Bulk Analysis Laboratory

Collected asbestos bulk samples were submitted under chain of custody for standard turnaround PLM analysis to EMSL Analytical in Minneapolis, MN. EMSL is NVLAP (#101234-0) accredited for bulk (PLM) asbestos analysis.

PLM Asbestos Bulk Sample Results

Positive samples identify building components as ACM. Asbestos-containing materials are regulated materials. ACM scheduled for disturbance or in poor condition are subject to handling and disposal according to all local, state, and federal regulations.

On April 6, 2021, a total of 5 bulk samples of what appeared to be 3 homogeneous area were collected at the subject property for PLM analysis.

The analytical results indicate that the following building materials DO contain asbestos:

o Window Glaze – 1st fl E Window (S side) – 4% Chrysotile

The analytical results indicate that the following building materials do NOT contain asbestos:

o Window Glazing – Other 1st floor windows o Concrete o Sheet Flooring o 12x12 Floor Tile + Adhesive o Wall Tile + Adhesive

The following building materials were NOT sampled and are presumed to be asbestos-containing.

o None

Conclusions

1. The window glazing on the 1st floor East Window (south end) contains 4% Chrysotile asbestos.

Recommendations

1. Because one window glazing sample came back as asbestos-containing, we must assume that other windows that were not tested contain glazing that is >1% asbestos, and must be considered asbestos-containing. The window glazing is considered a non-friable asbestos-containing material, even though sections of it are maginally damaged in some areas.

Limitations

The field observations, measurements, and research reported herein are considered sufficient in detail and scope to determine the asbestos content of the tested materials at the subject property.
