1.0 EXECUTIVE SUMMARY

Sunrise Environmental, Inc. has completed a Pre-Demolition Asbestos Inspection of the Dixie Lode Site. The asbestos inspection was performed by Mr. Scott D. Sanders of Sunrise Environmental, Inc. July 22nd, 2021. After identifying homogeneous areas of suspect Asbestos Containing Materials (ACM), the inspector collected samples from each homogeneous area. The samples were submitted to an independent laboratory where they were analyzed by polarized light microscopy.

Sunrise Environmental, Inc. collected and analyzed a total of thirty-two (32) samples from fifteen

(15) homogeneous areas for asbestos content, eight (8) of which were found to contain greater than 1% asbestos. Sunrise Environmental, Inc. did not presume any additional Homogeneous Areas as asbestos containing.

The materials found to contain greater than 1% asbestos at the site are listed below:

· Gray window glazing (H.A #4) (cabin)

· Gray window glazing (H.A #5) (cabin)

· Gray window glazing (H.A #7) (debris pile north of outhouse)

· Black sink undercoating (H.A. #8) (debris pile north of outhouse)

· Black gas-tank rustproofing (H.A. #11) (debris pile west of truck topper)

· Gray caulk (H.A. #12) (truck topper)

· Black tar with silver sealant (H.A. #13) (camper)

· Gray caulk (H.A. #14) (camper)

All of the materials listed in above must be removed prior to demolition or manual deconstruction of the cabin and clean-up of the debris piles is to be performed. Removal of these materials should be performed by a Colorado Department of Public Health and Environment Air Quality Control Commission (CDPHE-AQCC) licensed General Abatement Contractor (GAC) using personnel trained in asbestos removal techniques and personal protective equipment.

2.0 SCOPE AND FACILITY INFORMATION

2.1 Inspection Objectives and Scope

The White River National Forest requested Sunrise Environmental Inc. inspect the Dixie Lode Site for the presence of asbestos containing materials (ACM). Sunrise Environmental, Inc. performed a Pre-Demolition Asbestos Inspection in accordance with the requirements of 40 CFR 61, National Standards for Hazardous Air Pollutants (NESHAP), and Colorado Department of Public Health and Environment Air Quality Control Commission (CDPHE-AQCC) Regulation 8, which require that a structure be thoroughly inspected for the presence of asbestos-containing building materials prior to demolition.

Our scope of services included the following:

· Identify suspect asbestos containing materials (ACM) at the Dixie Lode Cabin and outhouse.

· Identify suspect asbestos containing materials (ACM) on the surface of the ground at the site.

· Collect bulk samples of all identified suspect materials in accordance with 40 CFR

763.86 and CDPHE-AQCC Regulation # 8.

· Submit the bulk samples to a NVLAP accredited asbestos laboratory for analysis;

· Specify the condition of the suspect ACM;

· Compile a final report of findings.

Sunrise Environmental, Inc. made reasonable efforts to locate and identify asbestos containing materials (ACM) at the Dixie Lode Cabin. The inspection was conducted by CDPHE-AQCC Certified Asbestos Building Inspector Scott D. Sanders, Certification #633.

2.2 Building Description

The 19’ x 22’ square foot cabin and the 5’ x 5’ square foot outhouse are primarily constructed of wood.

2.3 Review of Existing Information

No previous asbestos inspection documentation regarding the site was provided for review.

3.0 METHODS AND TECHNIQUES

3.1 Inspection

Sunrise Environmental, Inc. inspected the Dixie Lode Site to locate and identify friable and non-friable asbestos containing building materials. Mr. Scott D. Sanders of Sunrise Environmental, Inc. performed the inspection July 22nd, 2021. Mr. Scott D. Sanders is a CDPHE-AQCC certified asbestos building inspector. The inspector visually inspected the cabin to locate and identify suspect ACM, touched suspect ACM to determine friability, and determined the extent of homogeneous areas of friable and non-friable suspect ACM.

3.2 Bulk Sampling

Random bulk samples, representative of the suspect asbestos containing building materials of each homogeneous area, were collected according to guidelines published as Environmental Protection Agency (EPA) Final Rule: Title II of the Toxic Substances Control Act (TSCA), 15 USC, Sections 2641 through 2654 and in compliance with 40 CFR, Part 763 and CDPHE-AQCC, Regulation Number 8. Representative sampling is based on the following criteria:

1. The distribution of the suspect material throughout the homogeneous area.

2. The suspect materials physical characteristics and application.

3. Random sampling patterns determined for each homogeneous area.

Sample locations for Surfacing Materials were randomly determined according to the EPA “Pink Book” asbestos in buildings:

Simplified Sampling Scheme for Friable Surfacing Materials (1985).

Suspect materials sampled and analyzed should be considered representative of materials in each homogeneous area if:

1. They exhibit similar physical characteristics.

2. The application of the sampled material can be correlated to the application of un-sampled material.

Suspect materials similar in appearance and application were sampled as homogeneous areas.

Suspect materials were divided into three classifications and sampled according to applicable regulations based on classification of each homogeneous material and the quantity of each homogeneous material as listed below:

1. Surfacing Materials - Troweled on or sprayed on material

· 1,000 square feet requires a minimum of three (3) samples

· Greater than 1,000 square feet but less than or equal to 5,000 square feet requires a minimum of five (5) samples

· Greater than 5,000 square feet requires a minimum of seven (7) samples

2. Thermal System Insulation

· Each system requires three (3) samples

3. Miscellaneous - other suspect materials not classified in the above categories

· Sufficient samples to adequately characterize the materials with a minimum of two

(2) samples

After identifying homogeneous areas of suspect ACM, representative samples from each homogeneous area were collected. The inspector randomly selected the sample locations and collected samples in a manner to minimize the release of fibers into the air. At each sample location, the inspector collected a small bulk sample of the material using an appropriate tool (e.g, clean knife or chisel), and placed each bulk sample into an unused, uniquely labeled, sealable bag.

The inspector documented each Homogeneous Area, sample location, sample number and other pertinent information at the time of the inspection. A total of thirty-two (32) samples were collected for analysis from fifteen (15) Homogeneous Areas.

3.3 Sample Analysis

Bulk samples collected were submitted for analysis at Eurofins CEI, 730 SE Maynard Road, Cary, North Carolina, 27511 and were analyzed by Polarized Light Microscopy (PLM) for asbestos content. Eurofins CEI is accredited by the National Institute of Standards and Technology (NIST) under the National Voluntary Laboratory Accreditation Program (NVLAP). PLM was performed in compliance with guidelines established by the USEPA (EPA 600/R-93/116 Method).

A building material of a given homogeneous area is considered to be ACM based on a finding that at least one sample collected from the material showed asbestos present in an amount greater than one percent (1%). A building material is not to be considered ACM only if the results of all samples collected from the material showed asbestos content to be equal to or less than one percent (1%).

CDPHE-AQCC Regulation No. 8, Section III.A.1.c requires that if the asbestos content of a friable asbestos containing material is estimated to be 1% asbestos or less, but greater than 0%, the material must be treated as asbestos-containing or the material must be submitted for the point count analysis technique using Polarized Light Microscopy. If the point count result is different from the result obtained from visual estimation, the point count result must be used. EPA- NESHAP recommends point count analysis for visual estimations from greater than 1% to 10% to disprove false positive results or consider the material to be asbestos containing. None of the samples collected were submitted for point count analysis.

The analysis of the bulk samples was performed on July 27th, 2021 as listed in the Analytical Data Section of this report (See Appendix A). Condition assessments were performed by the accredited inspector at the time of inspection.

7.0 Inspector Comments

Sunrise Environmental, Inc. identified and sampled a total of fifteen (15) Homogeneous Areas, eight (8) of which were found to contain greater than 1% asbestos. Sunrise Environmental, Inc.

did not presume any additional building materials to contain greater than 1% asbestos. The CDPHE-AQCC requires the removal of friable materials and non-friable materials that may become friable during demolition activities prior to demolition. This asbestos inspection was performed for the purpose of demolition.

Sunrise Environmental, Inc. made reasonable efforts to locate and identify Asbestos Containing Materials (ACM) at the Dixie Lode Cabin site. The inspector performed destructive access to access inaccessible areas. If hidden unidentified materials are encountered during demolition, work should stop and additional bulk material samples should be collected to determine potential asbestos content.

No suspect materials were observed associated with the outhouse structure.

Rodent feces were observed within the cabin and camper at the site during the inspection, making Hantavirus a possibility. Proper precautions and Personal Protective Equipment (PPE) for Hantavirus should be considered by Contractors involved in abatement or demolition activities and any person entering the cabin or camper.

All asbestos-containing material quantities listed in Section 4.0 of this report are estimations and should be verified in the field by contractors bidding on asbestos abatement or demolition of the cabin. Asbestos Analytical Data can be found in Appendix A. Site Location Diagram & Site Map are located in Appendix B. Asbestos Bulk Sample Location Diagrams are in Appendix C.

Asbestos-Containing Material Location Diagrams are in Appendix D. Asbestos Certifications can be found in Appendix E of this report.

8.0 Conclusions and Recommendations

The materials found to contain greater than 1% asbestos at the site are listed below:

· Gray window glazing (H.A #4) (cabin)

· Gray window glazing (H.A #5) (cabin)

· Gray window glazing (H.A #7) (debris pile north of outhouse)

· Black sink undercoating (H.A. #8) (debris pile north of outhouse)

· Black gas-tank rustproofing (H.A. #11) (debris pile west of truck topper)

· Gray caulk (H.A. #12) (truck topper)

· Black tar with silver sealant (H.A. #13) (camper)

· Gray caulk (H.A. #14) (camper)

All of the materials listed above must be removed if manual deconstruction (demolition) of the cabin and clean-up of the debris fields is to be performed. Removal of these materials should be performed by a CDPHE-AQCC licensed General Abatement Contractor (GAC) using personnel trained in asbestos removal techniques and personal protective equipment.

The Occupational Safety and Health Administration (OSHA) requires contractors and workers be notified of the presence and location of asbestos and requires employers to protect employees from exposure to asbestos above the permissible exposure limit of 0.10 f/cc, as determined by personnel monitoring, over an 8-hour time weighted average. Appropriate asbestos training for workers is also required. Contractors are responsible to comply with OSHA 29 CFR 1926.1101 requirements.

Building and/or facility owners are required to notify prospective employers applying or bidding for work that can reasonably be expected to work in or occupy areas containing ACM and/or PACM, of the presence of such materials.

9.0 Limitations

The findings set forth in this report are strictly limited in time and scope to the date of the evaluation(s). The conclusions presented in the report are based solely on the services described therein, and not on scientific tasks or procedures beyond the scope of agreed upon services.

Because of the hidden nature of many building components, it may be impossible to determine if all building components have been located and subsequently tested. Destructive testing in some instances is not a viable option. Sunrise Environmental, Inc. does not, therefore, guarantee that all potential ACBM has been located. For the same reasons, estimates of quantities are subject to readily apparent situations. We do warrant, however, that the investigations and methodology reflect Sunrise Environmental, Inc’s best efforts based upon prevailing standard of care and due diligence in the environmental field.

The purpose of this report was to assess the physical characteristics of the subject Site with respect to the presence of asbestos containing building materials. No specific attempt was made to check on the compliance of present or past owners or operators of the Site with federal, state or local laws and regulations, environmental or otherwise.

Due to the limitations of the EPA 600 method, nonfriable organically bound materials (NOBs) such as vinyl floor tiles can be difficult to analyze via polarized light microscopy (PLM). EPA recommends that all NOBs analyzed by PLM, and found not to contain asbestos, be further analyzed by Transmission Electron Microscopy (TEM). Please note that PLM analysis of dust and soil samples for asbestos is not covered under NVLAP accreditation. Estimated measurement of uncertainty is available on request.

This report relates only to the samples tested or analyzed and may not be reproduced, except in full, without written approval by Eurofins CEI. Eurofins CEI makes no warranty representation regarding the accuracy of client submitted information in preparing and presenting analytical results.
