Terracon Project No. N1187151 July 11, 2018

1.0 INTRODUCTION

Terracon Consultants, Inc. (Terracon) conducted an asbestos survey of Building 34020at the Wright Patterson Air Force Base. The survey was conducted on June 25, 2018, by United States Environmental Protection Agency (USEPA)-accredited and State of Ohio certified Asbestos Hazard Evaluation Specialist (AHES) in general accordance with Terracon proposal number PN1187151 dated, May 3, 2018. Accessible interior and exterior building components were surveyed. Homogeneous areas of suspect asbestos-containing materials (ACM) were visually identified and documented. Although reasonable effort was made to survey accessible suspect materials, additional suspect but un-sampled materials could be located in walls, in voids, or in other concealed areas. Suspect ACM samples were collected in general accordance with the sampling protocols outlined in (USEPA) 40 Code of Federal Regulations (CFR) Part 763, Subpart E, known as the Asbestos Hazard Emergency Response Act (AHERA). Samples were delivered to an accredited laboratory for analysis by Polarized Light Microscopy (PLM).

A prior asbestos report for Building 34020 (dated December 3, 2015 by Lawhon & Associates) was provided by the Client to Terracon for review prior to the field survey; data from that survey was utilized as feasible A copy of the previous report is included in Appendix E (Client-Provided Information).

1.1 Project Objective

We understand that this survey was requested for the purpose of a potential demolition of Building 34020. Please note that asbestos surveys are required prior to renovation or demolition to satisfy requirements of the USEPA 40 CFR Part 61, Subpart M, the National Emission Standards for Hazardous Air Pollutants (NESHAP) regulation (as well as the state NESHAP equivalent).

2.0 BUILDING DESCRIPTION

Building 34020 is a vacant aircraft hangar with approximately 18,170 square feet of interior floor space.

3.0 FIELD ACTIVITIES

The survey was conducted by Mr. Joshua Vogel USEPA-accredited and OEPA certified AHES.

A copy of Mr. Vogel’s Ohio AHES credential is attached as Appendix D. The survey was conducted in general accordance with the sample collection protocols established in USEPA 40 CFR Part 763, Subpart E, Section 763.86, AHERA. A summary of survey activities is provided below.

3.1 Visual Assessment

Survey activities were initiated with visual observation of the accessible interior and exterior areas of the building to identify homogeneous areas of suspect ACM. A homogeneous area (HA) consists of building materials that appear similar throughout in terms of color and texture with consideration given to the date of application.

3.2 Physical Assessment

A physical assessment of each HA of suspect ACM was conducted to assess the friability and condition of the materials. A friable material is defined by the USEPA as a material which can be crumbled, pulverized, or reduced to powder by hand pressure when dry. Friability was assessed by physically touching suspect materials.

3.3 Sample Collection

Based on results of the visual observation, bulk samples of suspect ACM were collected in general accordance with USEPA AHERA sampling protocols. Samples of suspect materials were collected from randomly selected locations in each homogeneous area. Bulk samples were collected using wet methods as applicable to reduce the potential for fiber release. Samples were placed in sealable containers and labeled with unique sample numbers using an indelible marker.

July 11, 2018 ■ Terracon Project No. N1187151

Responsive ■ Resourceful ■ Reliable 3

The selection of sample locations and frequency of sampling were based on Terracon’s observations and the assumption that like materials in the same area are homogeneous in content.

Terracon collected a total of 110 bulk samples from 34 homogeneous areas of suspect ACM. A summary of suspect ACM samples collected during the survey is included as Appendix B.

3.4 Sample Analysis

Bulk samples were submitted under chain of custody to International Asbestos Testing Laboratories (IATL) of Mount Laurel, New Jersey for analysis PLM with dispersion staining techniques per USEPA methodology 600/R-93/116. The percentage of asbestos, where applicable, was determined by microscopic visual estimation. When applicable for samples determined by PLM to have a low asbestos content (<10%), the additional point count (PC) method was utilized. IATL is accredited under the National Voluntary Laboratory Accreditation Program (NVLAP), accreditation number 101165-0.

4.0 REGULATORY OVERVIEW

The asbestos NESHAP (40 CFR Part 61, Subpart M) regulates asbestos fiber emissions and asbestos waste disposal practices. The asbestos NESHAP regulation also requires the identification and classification of existing ACM according to friability prior to demolition or renovation activity. Friable ACM is a material containing more than 1% asbestos that, when dry, can be crumbled, pulverized, or reduced to powder by hand pressure. All friable ACM is considered regulated asbestos containing material (RACM).

The asbestos NESHAP regulation classifies material subject to demolition or renovation as either RACM, Category I non-friable ACM, or Category II non-friable ACM. RACM includes all friable ACM (pre-disturbance), along with Category I non-friable ACM that becomes friable (during disturbance), and Category I non-friable ACM subject to sanding, grinding, cutting, or abrading, or Category II non-friable ACM with a high probability of becoming crumbled, pulverized, or reduced to powder by forces expected to act on the material during disturbance. Category I non-friable ACM are exclusively asbestos-containing packings, gaskets, resilient floor coverings, and asphalt roofing products that contain more than 1% asbestos. Category II non-friable ACM are all other non-friable materials (other than Category I non-friable ACM) that contain more than 1% asbestos. Category II non-friable ACM generally include (but is not limited to) cementitious material such as cement pipes, cement siding (Transite™), cement panels, glazing, mortar, and grouts.

The Ohio Environmental Protection Agency (OEPA) adopted Chapter 3745-20 of the Ohio Administrative Code and implements the Asbestos NESAHP. The owner or operator must provide the OEPA district office or local air agency with written notification at least 10 business days prior

July 11, 2018 ■ Terracon Project No. N1187151

Responsive ■ Resourceful ■ Reliable 4 to the commencement of renovation or demolition projects. The OEPA also regulates friable asbestos abatement activities, asbestos personnel training, and issuance of asbestos professional certifications under OAC 3745-22. OEPA audits asbestos abatement projects and responds to public health emergencies where friable ACMs has been released; licensed contractors must submit a 10-business day notification prior to an abatement project where friable ACMs in quantities greater than 50 linear or 50 square feet are being removed. Please note that per OEPA regulations, non-friable floor tile if broken into pieces four (4) square inches or smaller are considered friable, and thus as a RACM.

The United States Occupational Safety and Health Administration (US OSHA) asbestos standard for construction (29 CFR 1926.1101) regulates workplace exposure to asbestos. The USOSHA standard requires that employee exposure to airborne asbestos must not exceed 0.1 fibers per cubic centimeter of air (0.1 f/cc) as an eight-hour time weighted average (TWA) and not exceed

1.0 fibers per cubic centimeter of air (1.0 f/cc) over a 30-minute time period - known as an excursion limit (EL). The TWA and EL are known as US OSHA’s asbestos permissible exposure limits (PELs). The US OSHA standard classifies construction and maintenance activities which could disturb ACM, and specifies work practices and precautions which employers must follow when engaging in each class of regulated work.

5.0 FINDINGS AND RECOMMENDATIONS

Based on the results of laboratory analysis regarding the bulk material samples collected, and data from the previous asbestos report, the materials listed below were identified to contain asbestos.

6.0 LIMITATIONS/GENERAL COMMENTS

In addition to the limitations indicated in other sections of this report, Terracon did not perform sampling which required demolition or destructive activities such as knocking large holes in walls, dismantling of equipment or removal of protective coverings. Reasonable efforts to access suspect materials within known areas of restricted access (e.g., crawl spaces) were made;

however, confined spaces or areas which may pose a health or safety risk to Terracon personnel were not sampled. Sampling did not include suspect materials which could not be safely reached with available ladders/man-lifts.

This asbestos survey was conducted in a manner consistent with the level of care and skill ordinarily exercised by members of the profession currently practicing under similar conditions in the same locale. The results, findings, conclusions, and recommendations expressed in this report are based on conditions observed during our survey of the building. The information contained in this report is relevant to the date on which this survey was performed, and should not be relied upon to represent conditions at a later date. This report has been prepared on behalf of and exclusively for use by Emersion Design, LLC for specific application to their project as discussed. This report is not a bidding document. Contractors or consultants reviewing this report must draw their own conclusions regarding further investigation or remediation deemed necessary.
