1.0 PURPOSE AND SCOPE OF SERVICES

The purpose of this project was to conduct an Asbestos-Containing Materials (ACM) survey and provide Asbestos Abatement Cost Estimates for identified ACM located in the L3600 - Anasazi

Heritage House located at Canyon Ancnts Natl Monument, Colorado. ATC Associates Inc.

(ATC) provided the services as outlined below:

Conduct a representative asbestos survey of the identified building, which includes the following:

1. Review existing asbestos reports for the building areas, if provided;

2. Survey all of the interior and exterior areas of the building, including building roofs;

3. Identify accessible suspect ACMs using Environmental Protection Agency (EPA)

Asbestos Hazard Emergency Response Act (AHERA) protocols;

4. Collect and analyze bulk samples of suspect friable and non-friable materials to eliminate suspect materials as asbestos containing;

5. Quantify ACMs, including material condition and location; and

6. Provide ACM abatement cost estimates for ACM identified during the survey of the building.

2.0 GENERAL SITE CONDITIONS

The building is a single story, wood framed structure, situated on a concrete foundation, covered by a metal roof. Reportedly, the building was constructed in 1999 and is approximately 2,359 gross square feet. Interior finishes include sheet flooring, carpet, drywall/joint compound, wall texture and acoustical ceiling texture. Exterior finishes consist of wood and vinyl siding.

3.0 REGULATORY STANDARDS

3.1 Asbestos Regulations

The survey was performed in accordance with Federal, State and local rules for conducting asbestos surveys to meet Occupational Safety and Health Administration (OSHA) and United

States Environmental Protection Agency (EPA) / National Emission Standards for Hazardous

Air Pollutants (NESHAP) requirements. The work was also performed in general accordance with AARCHER Subcontract Number 522-S003, dated August 12, 2009 and Task Order 522-

S003-001 (Rev. 9/14/09), dated September 14, 2009.

4.0 ASBESTOS-CONTAINING MATERIALS SURVEY AND ASBESTOS ABATEMENT

COST ESTIMATES

ATC representative, Mr. Todd Anderson, Senior Field Manager, an Asbestos Hazard Emergency

Response Act (AHERA) Accredited Asbestos Building Inspector/Management Planner/Project

Designer, State of Colorado Department of Public Health and Environment (CDPHE)

Certification #2157, assisted by Mr. Les Puvathingal, AHERA Accredited Asbestos Building

Inspector CDPHE Certification #15037 conducted the asbestos survey of the building on

November 18, 2009. All fieldwork was performed under the guidance of Mr. Fritz Leonard, an

AHERA Accredited Building Inspector/Management Planner/Project Designer CDPHE

Certification #15149.

The scope of the Asbestos-Containing Materials Survey included all of the accessible suspect building materials and finishes of the interior and exterior areas of the building, including building roofs. If ACM was identified in the building, Asbestos Abatement Cost Estimates were provided for each identified material.

Previous ACM survey reports for the building were not made available for review.

The building areas were visually inspected for the presence of building materials that are suspected to contain asbestos. Bulk samples of identified suspect ACMs were collected and placed into individual containers for transport to a National Voluntary Laboratory Accreditation Program

(NVLAP)/American Industrial Hygiene Association (AIHA)-accredited laboratory for analysis.

Materials visibly identified as non-asbestos (fibrous glass, foam rubber, wood, metal, etc.) were not sampled. The asbestos survey consisted of three basic procedures: 1) conducting a visual inspection of the structure and identifying functional spaces; 2) identifying homogeneous material areas of suspect surfacing, thermal system insulation, and miscellaneous materials; and 3) sampling accessible, friable and non-friable suspect materials.

4.1 Homogeneous Materials

Prior to collecting any samples, homogenous materials were identified and listed to develop a sampling strategy. A homogeneous material sampling area can be described as one or more areas of material that are similar in appearance and texture and that have the same installation date and function. The actual number of samples collected from each homogeneous sampling area was based upon criteria detailed in the following sections.

4.2 Hazard Assessment Factors

From the list of suspect homogeneous materials, a physical assessment was performed for each material on the list. A physical assessment includes evaluating the condition, assessing the potential for disturbance, and determining the friability of each material. Friability is a term used to describe the ease in which a building material inherently lends itself to disturbance. By definition, "friable" materials are those that can be crumbled or reduced to powder by hand pressure when dry. Each material on the list was further classified into one of three categories, which have specific sampling requirements for each category.

Surfacing Materials: Refers to spray-applied or troweled surfaces such as plaster ceilings and walls, fireproofing, textured paints, textured plasters, and spray-applied acoustical surfaces.

Thermal System Insulation: Refers to insulation used to inhibit heat gain or loss on pipes, boilers, tanks, ducts, and various other building components.

Miscellaneous Materials: Refers to friable and non-friable products and materials that do not fit in any of the above two categories such as resilient floor covering, baseboards, mastics, adhesives, roofing material, caulking, glazing, and siding. This category also contains wallboard and joint compound wall systems and acoustical ceiling tile.

All confirmed ACMs were then assessed by their condition as good (no visible damage or showing only very limited damage or deterioration), damaged (less than 25% localized damage or 10% distributed damage), significantly damaged (25% or greater localized damage or 10% or greater distributed damage) per Title 40 Code of Federal Regulations Part 63.

4.3 Sampling Strategy

The asbestos inspection was conducted in general accordance with the AHERA requirements using a minimum number of samples collected for each homogenous material, which also meets the sampling requirement found in 29 CFR 1926.1101.

If the analytical results indicated that all the samples collected per homogenous material did not contain asbestos, then the homogenous material would be considered a non-ACM. However, if the analytical results of one or more of the samples collected per homogenous material indicate that asbestos is present in quantities of greater than 1 percent asbestos by weight (as defined by EPA), all of the homogenous material would be treated as an ACM regardless of any other analytical results.

Material which can visually be determined to be non-asbestos (i.e., fibrous glass, foam rubber, metal, etc.) by the accredited inspector are not required to be sampled.

Miscellaneous materials require adequately representative sampling, which is typically done by collecting from one to three samples per material. Inspectors typically rely on other survey observations such as the condition, friability, and quantity of material to determine what would be a sufficient amount of samples to accurately evaluate the presence or absence of asbestos content. For this survey, three samples per each homogenous miscellaneous material were collected.

Actual collection of a bulk asbestos sample involves physically removing a small piece of material and placing it in a marked, airtight container. Sample containers are marked with a unique identification number, which is also noted in the field notes.

4.4 Suspect Asbestos-Containing Material

Twenty-five bulk asbestos samples were collected from the building and 29 sample layers were analyzed by Polarized Light Microscopy (PLM) based on the number of distinct layers (materials) associated with each bulk sample. For example, floor tile and associated mastic are collected as one bulk sample but are analyzed as two distinct materials by the asbestos laboratory, as required by

NVLAP.

4.5 Laboratory Analytical Results

Bulk samples were analyzed by ATC Associates Inc. Analytical Laboratory located in Centennial, Colorado, using PLM according to EPA method 600/R-93/116. This laboratory participates in the

NVLAP, a quality assurance program for PLM, and is accredited by the National Institute of

Standards and Technology (NIST).

Any material that contains greater than 1 percent (>1%) asbestos by PLM is considered an ACM and must be handled according to OSHA, EPA, and applicable state and local regulations. In addition, the U.S. Occupational Safety and Health Administration (OSHA) define asbestos as building materials containing between one tenth of one percent and one percent (0.1%-1%).

For friable materials, when the amount of asbestos in the sample material is reported as “None-

Detected” by PLM analysis, no further verification of the sample results by Point Counting

Methodology is recommended.

For friable materials, when the amount of asbestos in the sample material is reported as “Trace

Asbestos Detected” or less than 10% asbestos by PLM analysis, the client may either assume the amount to be greater than 1% and treat the material as ACM or require further verification of the amount by Point Counting Methods. If the result obtained by Point Counting is different from the result obtained by PLM analysis, the Point Count Method result should be used.

For non-friable materials, when the amount of asbestos in the sample material is reported as greater than 1% asbestos by PLM analysis, no further verification of the sample results by alternative methods of identification such as Transmission Electron Microscopy (TEM) Chatfield Method is recommended.

For non-friable materials such as vinyl/asphaltic products (floor tiles/ floor sheeting, mastics, shingles etc), where small, thin asbestos fibers may have been potentially milled into the non-organic binder matrix, when the amount of asbestos in the sample material is reported as “Non-

Detected” by PLM analysis, due to the difficulty in analyzing such small, thin asbestos fibers in resinously bound materials by PLM analysis, EPA recommends but does not require that these types of materials, which were reported as non-ACMs by PLM, be further analyzed using TEM

Chatfield Method. ATC did not conduct such analysis.

The results of the laboratory analysis are summarized in tabular form in Section 5.0. The laboratory analytical report and corresponding chain-of-custody documents are included in

Appendix A. Results are reported in percent asbestos by volume and indicate the types of asbestos. Other common non-asbestos components may also be noted on the analytical reports.

A drawing(s) showing bulk sample locations is provided in Appendix B. Inspector and laboratory accreditations are provided in Appendix C. The Bureau of Land Management Facility

Spreadsheet is provided in Appendix D and lists whether or not asbestos was identified at the building as well as the presence or absence of asbestos in each of the building materials sampled during for the survey of the building. Appendix E presents photographs of up to two ACM’s identified in the building (if present). Appendix E is not intended to show all ACM’s identified in the building.

6.0 CONCLUSIONS

The results of the asbestos survey conducted at the L3600 - Anasazi Heritage House, Canyon

Ancnts Natl Monument, Colorado facility building indicate that: three of the accessible suspect building materials sampled were found to contain more than 1% asbestos.

Contractors and employees working in this building should be made aware of the possibility that concealed ACMs may be found during demolition/renovation. They should be advised not to disturb known or suspect ACMs without owner approval.

Any concealed building materials discovered during maintenance or renovation activities, which are suspected to contain asbestos, should be sampled and analyzed to confirm the presence of asbestos prior to disturbing.

The EPA has not prohibited the manufacture and import of miscellaneous materials, such as vinyl floorings, mastics, roofing materials, etc. As a result, any future replacement materials should be checked for the presence of asbestos prior to installation.

7.0 ASSUMPTIONS AND LIMITATIONS

The results, findings, conclusions, and recommendations expressed in the report are based only on conditions that were noted during ATC’s inspection of the L3600 - Anasazi Heritage House building located at the Canyon Ancnts Natl Monument, Colorado.

The selection of sample locations and frequency of sampling was based on ATC’s observations and the assumption that like materials in the same area are homogeneous in content. Limited destructive investigation was conducted as needed. Concealed ACMs may exist in concealed areas not investigated or identified.

The report is designed to aid the client in understanding the extent of ACM issues as they pertain to the “Recognition and Measurement of Asbestos-Related Cleanup Costs,” Technical Bulletin

2006-1, prepared by the Federal Accounting Standards Advisory Board, dated September 28, 2006 and to the renovation/demolition areas of the facility building areas. It should be noted that this report is not a complete Asbestos Abatement Specification or Work Plan.

Our professional services have been performed, our findings obtained, and our conclusions prepared in accordance with customary principles and practices in the fields of environmental science and engineering. This statement is in lieu of other statements either expressed or implied. This report does not warrant against future operations or conditions, nor does it warrant against operations or conditions present of a type or at a location not investigated.

Asbestos abatement cost estimates were obtained from asbestos abatement contractors who have not visited the site and have not seen the ACM to be abated. The costs provided herein, are magnitude estimates of costs with the following assumptions made:

• Assumes free and clear access to the work area during working hours.

• Assumes one mobilization to complete the abatement of one ACM.

• Assumes both power and water at no cost to contractor.

• Assumes protect in place all above ceiling electrical wiring, fire alarm, and wifi cables.

• Does not include the demolition of any building components other than the ACM.

• Pricing assumes that any required inspections and air testing is provided by the building owner or owners representative.

• Assumes that no special conditions are added by any state, or local regulatory agency.

• Work hours 7:00 am to 5:00 pm Monday through Friday.

• Not be held responsible for packaging, moving or damage to items being moved, nor for providing storage and or inventory of these items. If storage or inventory is needed the owner will provide what is necessary. Responsibility of any personal items is the owners.

• No delays interfering with the diligent execution of the work beyond contractors control will be encountered.

PLM samples were analyzed utilizing the Environmental Protection Agency's Test Method: Method for the Determination of Asbestos in Building Materials (EPA 600/R-93/116. July, 1993). Reporting Limit <1% Asbestos. Additional treatment and tests may be required to accurately define composition (i.e. ashing, extractions, acetone treatment, andTEM). Unused portions of samples are archived for one year unless client requests special handling.

Asbestos content of mastic/adhesive is separated from total percent asbestos and other materials.

Laboratory analysis was accomplished utilizing an Olympus BH-2 polarized light microscope. The microscope is equipped with dispersion staining lenses.

ATC Associates, Inc. is accredited by NVLAP Bulk Asbestos Sample Quality Assurance Program (Lab Code 102031).

ATC participates in the NVLAP Bulk Asbestos Sample Quality Assurance Program and maintains an in-house QC/QA program for bulk samples whereby 10% of all submitted samples are reanalyzed and documented in a Quality Control Manual. ATC also participates in a quarterly round robin QC/QA program for bulk samples with several accredited laboratories throughout the United States. Current and past QC/QA program results are available in the laboratory for inspection.

Samples were analyzed by Jeff Lomme, Laboratory Director. Mr. Lomme is a professional geologist who has successfully completed the McCrone Institutes's "Advanced Asbestos Identification" Course.

Approved Signatory :

The non-detection of asbestos fibers in floor tile by PLM is of itself inconclusive. Confirmation by Transmission Electron Microscope (TEM) is recommended for negative floor tile samples.

This report must not be used by the client to claim product endorsements by NVLAP or an agency of the U.S. government.
