HEFLEY GYMNASIUM

1 INTRODUCTION

Grande River Environmental, LLC (GRE) was contracted by Colorado Northwestern Community College (CNCC) to conduct a limited asbestos inspection of materials beneath the Hefley Gymnasium floor located on the CNCC campus. The inspection was conducted in accordance with applicable Environmental Protection Agency (EPA), Occupational Safety and Health Administration (OSHA), and Colorado Department of Public Health and Environment (CDPHE) regulations prior to replacing the gymnasium floor. The purpose of this report is to present the findings of the inspection conducted on September 17, 2020

2 ASBESTOS INSPECTION

Asbestos sampling was completed by Jake Harris, a GRE asbestos inspector certified by the CDPHE and the EPA. Copies of the inspector’s certifications are attached to this report. This survey was performed in accordance with CDPHE Regulation No. 8 and AHERA regulations governing asbestos inspections. An asbestos inspection is required prior to conducting demolition or renovation activities.

Bulk samples of various suspect asbestos-containing materials (ACM) were collected and submitted to an independent laboratory for polarized-light microscopic (PLM) analysis.

Sample locations are described on the attached sample data sheets.

Asbestos sampling is conducted by segregating building materials into sampling units called homogeneous areas. A homogeneous area is defined as a material that is uniform in texture and color and appears identical in every other respect.

Once suspect materials are identified, they are classified as friable or non-friable. The EPA distinguishes between friable and non-friable forms of ACMs. Friable materials, when dry, can be crumbled or reduced to powder by hand pressure, whereas non-friable materials cannot.

Friable materials are more likely to release particulate dust into the air, especially during renovation and demolition activities. Therefore, the distinction between friable and non-friable homogeneous material is important.

September 18, 2020 2

Non-friable materials are further divided into two categories as defined by EPA. Category I non-friable materials that are in good condition may remain during building demolition provided these materials are not rendered friable during demolition. Category II non-friable materials must be removed prior to conducting renovation or demolition activities.

2.1 Asbestos Sampling Strategy

The Bulk Sampling Strategy shown in Table 1 was developed based on EPA and CDPHE regulations and was used to determine the minimum number of samples to be collected of each suspect material.

More than 5,000 SF 7 Thermal System Insulation - - - LF / SF / EA 3

Miscellaneous Materials - - - LF / SF / EA 2 Note: SF = Square feet LF = Linear feet EA = Each

GRE collected bulk samples of the homogeneous materials in a random and representative manner, as determined by the inspector. A minimum of one composite core sample that included all layers within the suspect material was obtained from each homogeneous area. Samples from soft friable materials were obtained by removing a small portion using wetting techniques. The sampler washed equipment following collection of each sample in order to minimize the potential for cross-contamination between samples. The sampler assumed that materials in inaccessible locations were similar to those in accessible locations, in order to limit the amount of destruction in the sampling process. All samples were placed in sealed, labeled containers, and the sample descriptions and locations were recorded.

Accessible spaces were inspected for homogeneous areas of building materials that potentially contain asbestos. The nature, extent, and condition of each type of potential ACM were cataloged. Sampling forms for each homogeneous area were prepared describing the type of material, identifying characteristics, and location of the sample. These forms are included in Appendix A of this report.

2.2 Asbestos Laboratory Analyses

Samples were submitted to an independent laboratory for analysis. Collected samples were analyzed by Reservoirs Environmental Services, Inc. (NVLAP Accreditation No. 101896) of Denver, Colorado, using polarized-light microscopy (PLM), a bulk sample analysis method

September 18, 2020 3 established by the National Voluntary Laboratory Accreditation Program (NVLAP). Bulk asbestos samples were analyzed using EPA Method 600/R-93/116. While the EPA does not “certify” laboratories, analytical methods follow EPA’s recommended protocols using a NVLAP accredited laboratory. The laboratory analytical data report is attached.

2.3 Asbestos Chain-of-Custody

A chain-of-custody record was used to track the possession and transfer of each sample from the time of field collection through laboratory analysis. The record contained the following: sample tag number, signature of collector, date of collection, identification of sampled material, requested laboratory analysis, signatures of individuals in custody of the samples, and record of possession. A copy of the chain-of-custody form is attached.

3 ASBESTOS INSPECTION RESULTS

Laboratory results from the asbestos inspection are summarized below. Samples of materials that contain greater than one percent (>1%) asbestos are considered ACM by the EPA and CDPHE. Samples that contain any amount of asbestos greater than none detected (ND) are recognized and covered by the OSHA Asbestos in Construction Standard found at 29 CFR

1926.1101. Homogeneous material descriptions, locations, and quantities as well as analytical results are summarized in Table 2.

4 CONCLUSIONS & RECOMMENDATIONS

This report presents the findings of a limited asbestos inspection conducted on September 17, 2020 at the Hefley Gymnasium on the CNCC campus in accordance with EPA and CDPHE regulations. The objective of this inspection was to identify the location and extent of asbestos-containing materials (ACMs) prior to gymnasium floor removal and replacement.

Bulk samples of suspect ACMs were obtained from the structure and submitted to an independent laboratory for polarized-light microscopic (PLM) analysis. Following are the recommendations to handle the materials based on their asbestos content, friability, and category:

September 18, 2020 4

Vermiculite Insulation – The insulation present beneath the gymnasium floor was identified to contain less than 0.25% asbestos; therefore, the materials are not governed by EPA or CDPHE regulations and may remain in the structure during demolition. However, materials that contain any amount of asbestos require compliance with the OSHA Asbestos in Construction Standard found at 29 CFR 1926.1101. Renovation or demolition activities involving materials that contain less than 1% asbestos require the use of wet methods and prompt clean-up and disposal of debris. The regulation prohibits employee rotation as a means of reducing employee exposure. The standard has other requirements for worker protection during asbestos removal.

If the material will remain in the structure during renovation or demolition, disturbance activities should be conducted in a manner to avoid contaminating site soils. Handling, removal, and disposal of soils containing any amount of asbestos may be regulated under the CDPHE Solid Waste Regulations.

5 QUALIFICATIONS AND LIMITATIONS

GRE conducted this investigation in a manner consistent with current professional practices.

This assessment was limited to the sampling locations and analyses described in the report. No other sampling or analyses were conducted during this investigation. Only readily accessible spaces were inspected; therefore, it is possible that ACM or other hazardous building materials may exist in areas that were inaccessible during this non-destructive inspection. Any materials not identified in this report should be assumed asbestos containing until proven otherwise. It is possible that additional reports or investigations could alter the conclusions of this assessment.

Materials and areas that were not accessed, sampled, and/or assessed include:

• Mechanical equipment interiors, including boilers, furnaces, electrical equipment, and ducting

• Interior of enclosed chases and soffits

• Behind walls that are inaccessible

• Above ceilings that are inaccessible

• Buried or subgrade building materials

Any addition to or alteration of the building should be documented and the inspection report should be amended. THIS DOCUMENT IS NOT INTENDED FOR BIDDING PURPOSES This report is intended for use only by the client. Any future use of this report by anyone other than the above-referenced client will require authorization by GRE and possible updating of the report.
