Executive Summary:

In May of 2021, Cumberland Analytical Laboratories, Inc. (CALI) was retained by Mr. Warren

Bieger and Mr. Daniel M. Gibbs of Frog Switch to conduct an Asbestos Identification Survey at the Frog Switch Facility located at 600 East High Street in Carlisle, Pennsylvania to identify suspect Asbestos-Containing Materials (ACM) from within the structures. The entire facility was evaluated during the survey.

The U.S. Environmental Protection Agency (EPA) defines ACM as any material that contains greater than 1% asbestos by PLM analysis. All sampled materials which contained one or more of the following asbestos types above 1% by laboratory analysis would be defined as ACM:

chrysotile, amosite, crocidolite, tremolite, anthophyllite, or actinolite.

The Occupational Safety and Health Administration (OSHA) defines ACM as any material that contains a detectable amount of asbestos. Therefore, materials that contain less than 1% asbestos would be regulated by OSHA under 29 CFR 1926.1101 (Construction) and 29 CFR 1910.1001

(General Industry). Any disturbance and/or removal of an ACM must be performed in accordance with the OSHA regulations by professionally trained and protected individuals using proper work practices and engineering controls.

The Scope of Work for this survey consisted of a visual inspection of all accessible areas within the select areas of the structures to identify suspect asbestos-containing materials. Bulk samples were collected as part of the survey to confirm or dismiss the presence of asbestos within the accessible suspected materials. During the sampling of suspect homogeneous materials from the structure a total of 111 homogeneous materials were analyzed. The results of the ACM survey performed have confirmed that asbestos-containing materials were found from within the structure:

• 15 Linear Feet of Rope Material in the Frog Shop Old Boiler Room.

• 2,000 Linear Feet of Thermal System Insulation in the Old Frog Shop

• 2,000 Ft.² of Asbestos Drywall Compound in the Machine Shop Bathroom

• 90,000 Ft.² of Roofing Material Foundry and Office Building Combine

• Entire Office Building Drywall Compound – No Quantity Known

Please review the Polarized Light Microscopy (PLM) Results Data Tables for additional sample information.

• Please note that, while this survey was performed in a thorough manner to locate and sample all suspect materials, additional suspect materials or undocumented asbestos-containing materials may still be located within the building in such areas as inside wall, ceiling, and floor cavities, underground or buried locations, roofing, HVAC equipment, coated/wrapped electrical wire/conduits and other inaccessible location. These materials may not be observed until renovation/demolition activities are commenced.

• Any materials not listed or specifically identified as part of this survey must be positively identified to verify the existence or absence of asbestos prior to the start of future demolition or renovations.

Methods and Analysis – Asbestos PLM Bulk Sampling:

Asbestos Sampling:

All samples were collected by a Pennsylvania Licensed Certified Asbestos Building Inspector to ensure efficient scheduling, priority analysis, and thorough documentation and record keeping during the survey. Bulk samples were collected from accessible suspected ACM within the structure areas during the survey under EPA recommended procedures to minimize fiber release and performed in accordance with EPA 40 CFR Part 763 SubPart E. Core samples of each material were collected to its substrate by penetrating the materials outer covering. Duplicate samples of similar materials from adjacent locations were compared for uniformity of texture and color. All samples were placed in sealed containers and labeled with an identifying code. A chain of custody for each collected sample was documented throughout the sample collection process to ensure proper quality control.

Asbestos Sample Analysis:

Bulk samples collected during this survey were packaged for proper shipment and delivered to

Eckhart Environmental Services, LLC, an American Industrial Hygiene Association (AIHA) accredited laboratory located in Media, Pennsylvania. Samples were analyzed using Polarized

Light Microscopy (PLM) with central stop dispersion staining techniques, using the EPA's

"Method for the Determination of Asbestos in Bulk Building Materials" and Analytical Method

EPA 600/R-93/116. The detection limit of this analytical method is one percent (1%) asbestos by weight.

Asbestos is present if the material analyzed is greater than one percent (>1%) by weight. This stipulation is outlined in the EPA Publication EPA 500/5-85-028, Section 2.2.2.2. Some building/structure materials may contain asbestos concentrations below the 1% by weight and can be documented via point counting or "trace" detection levels.

Asbestos Standards:

Federal regulations promulgated by the Environmental Protection Agency prohibit the use of asbestos materials for fireproofing and insulation where the material contains more than one percent asbestos by weight. In general, the higher the percentage of asbestos, the more fibers that can be released and cause contamination to the structure environment. However, substantial fiber release can occur in damaged or deteriorating materials even where asbestos content is low.

The condition of the ACM and its potential for disturbance (fiber release) may be used to determine if corrective measures should be taken. Evidence of water damage, physical damage, and the presence of broken or crumbled materials on the floor are signs that fiber release has occurred, is occurring or may occur in the future.

Inspection Date: May 3, 2021 and May 7, 2021

CALI Project Number: 20-1034-019

Health experts agree that exposure to airborne asbestos, regardless of concentrations, involves a health risk. Persons exposed to asbestos have an increased risk of developing asbestosis, lung cancer and mesothelioma.

The EPA currently recognizes four abatement methodologies to control exposure to airborne asbestos fibers. Specifically, these are removal, encapsulation, enclosure, operations, and maintenance. Properly conducted and supervised removal of asbestos material is the only method, which entirely eliminates asbestos exposure.

The current EPA recommended "clean air" asbestos limit for clearance testing during an asbestos abatement project is 0.01 Fibers per cubic centimeter (F/cc) by Phase Contrast Microscopy (PCM).

This level is also recognized as a "clean" level for background air levels in occupied buildings/structures.

If the purpose of this inspection was for documentation of asbestos-containing materials prior to structure renovation/demolition, please consult the appropriate local, state, and other relevant governmental regulatory agencies to ensure that proper procedures for notifications, abatement (if required), and material disposal and hauling are adhered to always. Please note that the abatement contractor may require adequate sources of water and electricity during removal activities.

Since the purpose of this inspection, as described to CALI, was for the determination of Asbestos-

Containing Materials prior to renovation activities, please consult the appropriate local, state, and other relevant governmental regulatory agencies to ensure that proper procedures for notifications, abatement (if required), and material disposal and hauling are adhered to always.

Conclusion/Recommendations:

Proper precautions should be taken when performing work in and around the identified asbestos materials and other materials you may encounter as suspect asbestos. This is especially Important and required when working in an occupied structure. Any potential renovation/demolition plans should include proper procedures for treatment of this asbestos material, as deemed necessary.

Disclaimer:

This survey only contains sample results from physical bulk samples collected during this inspection. Any other suspect asbestos materials identified within this structure that conflict with this report's findings should be sampled by a licensed building inspector prior to their removal to ensure no materials are misidentified as non-asbestos.

The Scope of Work of this survey was performed in such a manner to access all suspect materials.

Select removal of flooring was performed to attempt to access any additional suspect material.

With any structure of this general age and size, additional asbestos-containing materials may still be located within previously un-accessible locations. These areas include, but are not limited to, locations such as within wall and ceiling cavities, in unidentified pipe chases, within underground locations or buried materials, under flooring and/or sub-flooring, or in additional original roofing materials.

Also note that the HVAC systems and their internal buildings, including boiler units, water heaters, air conditioning and ventilation system, etc., were not disassembled and inspected due to the safety concerns of the technician performing the survey, as utilities were in service at the time of inspection.

While the results and information of these analyses are considered to be reliable, CALI assumes no responsibility for the accuracy of the results.

Data and other information in this report are only valid for the prevailing conditions identified during this investigation and will be kept confidential. Any information contained in this report will not be released to third parties without the expressed written consent of the client except where required by law.
