1. INTRODUCTION

In accordance with your request and authorization to proceed, Ninyo & Moore has conducted a

Limited Hazardous Building Materials Survey (HBMS) of Room 102 at Falcon Stadium at the

United States Air Force Academy (USAFA) in Colorado Springs, Colorado.

Ninyo & Moore understands the area is scheduled for renovation. Therefore, a Limited HBMS was conducted to identify and quantify potentially hazardous building materials prior to renovation.

This report has been prepared in accordance with generally accepted environmental science and engineering practices and applicable federal and state regulations. The report is based upon site conditions at the time of the field activities, and provides documentation of our findings and recommendations.

2. PURPOSE AND SCOPE OF SERVICES

The purpose of the HBMS was to assess and quantify asbestos-containing material (ACM), and paint coatings that contain lead.

Ninyo & Moore performed the following services:

Visual assessment of accessible areas to evaluate the presence of suspect ACM and lead paint.

Collection of building material samples and submittal of these samples to an independent laboratory for asbestos analysis by polarized light microscopy (PLM).

Collection of paint chip samples and submittal of these samples to an independent laboratory for lead analysis in general accordance with Environmental Protection Agency (EPA) SW-

846 Method 3050B/7000B.

Preparation of this report, presenting the data and summarizing the methodology used. This report includes a site description, figures, laboratory testing information, conclusions and recommendations, and tables summarizing the assessed building materials.

501013006 R 2

3. SITE DESCRIPTION

The subject site is Room 102 at Falcon Stadium at the USAFA in Colorado Springs, Colorado.

Room 102 is a media meeting room, and was constructed within a materials storage area adjacent to the south end of the stadium field level. With the exception of the small (approximate 300 square-feet) media room area, Room 102 is a concrete-walled storage area. Most of the storage area portion of Room 102 is unpainted concrete. The media room area of Room 102 is a drywall room, within the larger storage area structure.

4. PHYSICAL LIMITATIONS

No physical limitations, such as locked rooms and fenced areas, were encountered during the

HMBS. However, access to the interstitial wall and ceiling spaces of the media room area was limited. Therefore, there is a possibility that during renovation activities, additional ACM may be encountered in these spaces. Suspect materials encountered during renovation activities that have not been assessed previously may either be assumed to be ACM and handled accordingly, or may be sampled and analyzed at that time to assess whether they are asbestos-containing.

5. HAZARDOUS BUILDING MATERIAL SURVEY

On June 1, 2017, Ninyo & Moore conducted a Limited HBMS that included an asbestos inspection and limited lead sampling.

5.1. Asbestos Inspection

Mr. Steven Truesdale, a Colorado Department of Public Health and Environment (CDPHE)-certified Asbestos Building Inspector with Ninyo & Moore, conducted the asbestos inspection. The inspection was conducted in general accordance with the Colorado Air

Quality Control Commission’s Regulation 8, Part B (Regulation 8).

5.1.1. Sample Collection

A preliminary visual assessment of suspect ACM was conducted and homogeneous areas (areas in which the materials are uniform in color, texture, construction or

501013006 R 3 application date, and general appearance) were identified. Each homogeneous area was observed for material type, location, condition, and friability. Representative samples were collected from each homogeneous material, within the limitations of the inspection, using EPA-recommended sampling procedures. Building materials that were sampled and analyzed for the presence of asbestos are summarized in Table 1.

5.1.2. Laboratory Analyses and Results

A total of 10 samples of suspect ACM were collected and submitted to EMSL Labs, Inc.

(EMSL) of Denver, Colorado for analysis. EMSL is a CDPHE-registered asbestos laboratory and is accredited by the National Voluntary Laboratory Accreditation

Program (NVLAP No. 200828-0) for bulk asbestos fiber analysis. The samples were analyzed by PLM for the presence and quantification of asbestos fibers, in general accordance with EPA Method 600/R-93/116. A copy of Ninyo & Moore personnel and laboratory certifications are presented in Appendix A.

The lower limit of reliable detection for asbestos using the PLM method is approximately 1% by volume. Materials containing asbestos in amounts less than 1% but in excess of 0.1% are defined as containing “trace” amounts. Copies of the laboratory analytical reports and chain-of-custody records are presented in Appendix B.

5.1.3. Findings and Opinions

The findings of the asbestos inspection are based on our visual observations and laboratory analysis of suspect building materials. Based on the analytical results, the materials sampled were not reported to contain asbestos.

501013006 R 4

5.2. Lead Sampling

Limited lead sampling was conducted to assess the lead content of paint coated surfaces.

5.2.1. Assessment

Ninyo & Moore conducted a visual assessment for possible lead-based paint (LBP). The sampling was conducted in general accordance with applicable federal and state regulations within the scope of this assessment.

5.2.2. Laboratory Analyses and Results

A total of three samples of suspect LBP were collected and submitted to EMSL for analysis. EMSL is accredited by the American Industrial Hygiene Association (AIHA

No. 157245) for environmental lead analysis The samples were analyzed by atomic absorption spectroscopy in general accordance with EPA SW-846 Method

3050B/7000B.

LBP is paint with a lead concentration in excess of the EPA total threshold limit concentration of 5,000 milligrams per kilogram (mg/kg), 5,000 parts per million (ppm), 1 milligram per square centimeter (1.0 mg/cm ), or 0.5 percent by weight. Paint with a lead concentration in excess of the laboratory reporting limit but less than the EPA total threshold limit is considered to be lead-containing paint (LCP).

A Summary of Lead Sample Results is presented in Table 2. Copies of the laboratory analytical reports and chain-of-custody records are presented in Appendix C.

5.2.3. Findings and Opinions

The findings of this assessment are based on limited paint chip samples collected from the site. None of the samples collected were reported to contain lead exceeding the EPA total threshold limit. Although none of the samples are considered LBP by definition, two of the samples were reported to have lead above the laboratory analytical reporting limit and are considered LCP.

501013006 R 5

The Occupational Safety and Health Administration (OSHA) lead standard for the construction industry does not make a distinction between working on painted surfaces with greater than 0.5% lead and those that have less. Since there is some measurable lead in the wall paint of the storage area, a potential exists of occupational exposure to lead during remodeling when the painted surfaces are disturbed via sanding. Should paint in the storage area be sanded or disturbed, during a remodeling effort, an initial air monitoring scope should be conducted to determine if the sanding induces an airborne lead concentration above OSHA action levels or permissible exposure limits.

6. RECOMMENDATIONS

Based on the analytical results of the bulk samples collected during the limited asbestos inspection and limited lead sampling, no ACM or lead-based paint was identified. However, detectable levels of lead were reported in two of the paint chip samples. Therefore the following recommendations are provided:

Any suspect ACM or LCP discovered during renovation that was not assessed during this or previous inspections should be sampled and analyzed for asbestos content prior to disturbance.

Should paint in the storage area be sanded or disturbed, during a remodeling effort, an initial air monitoring scope should be conducted to determine if the sanding induces an airborne lead concentration above OSHA action levels or permissible exposure limits.

7. LIMITATIONS

Ninyo & Moore's opinions and recommendations regarding environmental conditions, as presented in this report, are based on limited sampling and analysis. The samples collected and used for testing, and the observations made, are believed to be representative of the area(s) evaluated. However, if additional suspect ACM or hazardous building materials are encountered during demolition activities, these materials should be sampled by qualified personnel, and analyzed prior to further disturbance.

501013006 R 6

The environmental services described in this report have been conducted in general accordance with applicable regulation and the standard-of-care exercised by environmental consultants performing similar work in the project area. Variations in site conditions may exist and conditions not observed or described in this report may be encountered during subsequent activities.

This document is intended to be used only in its entirety. No portion of the document, by itself, is designed to completely represent any aspect of the project described herein. Ninyo & Moore should be contacted if the reader requires any additional information, or has questions regarding content, interpretations presented, or completeness of this document.

The environmental interpretations and opinions contained in this report are based on the results of laboratory tests and analyses intended to detect the presence of ACM and lead in samples collected from the subject site. The testing and analyses have been conducted by an independent laboratory, which is accredited by the NVLAP and AIHA for bulk asbestos fiber analysis and lead analysis. Ninyo & Moore has no involvement in, or control over, such testing and analysis.

Ninyo & Moore, therefore, disclaims responsibility for any inaccuracy in such laboratory results.
