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 L1995 – Hanksville Office located at Richfield Field Office, Utah. Tetra Tech provided 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 slab on grade foundation, covered by a rubber roof. Reportedly, the building was constructed in 1981 and is approximately 3,320 gross square feet. Interior finishes include drywall, ceiling panels, and vinyl sheet flooring.

The exterior finish consists of metal siding.

3.0 REGULATORY STANDARDS

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-S004, dated May 27, 2010 and Task Orders 522- S004-001, dated June 1, 2010 and 522-S004-002, dated July 27, 2010.

Additionally, all work conducted within the State of Utah was conducted in accordance with Asbestos Certification, Asbestos Work Practices, and Implementation of Toxic Substances Control Act, Title II, Section R307-801, Utah Air Conservation Rules.

ABATEMENT COST ESTIMATES

Tetra Tech representatives Mr. Ryan Egan, Mr. Daniel Lawrence, and/or Mr. Mark Daley conducted the asbestos survey of the building on July 28, 2010. Mr. Egan is an AHERA and State of Utah accredited Building Inspector, Management Planner, Project Designer and Supervisor (Certificate Number ASB-4437). Mr. Lawrence and Mr. Daley are AHERA and State of Utah accredited Building Inspectors (Certificate Numbers ASB-4457 and 4443, respectively).

Tetra Tech is a State of Utah certified Asbestos Company (certificate ASBC-358). All field work was performed by and/or under the guidance of Mr. Ryan Egan.

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 meet 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

21 bulk asbestos samples were collected from the building and 37 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 FRS Geotech, Inc. analytical laboratory located in Denver, Colorado, using PLM according to EPA method 600/R-93/116. This laboratory participates in the NVLAP, a quality assurance program for PLM.

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 nonorganic binder matrix, when the amount of asbestos in the sample material is reported as “None-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. Tetra Tech 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, and Appendix D presents photographs of all ACM’s identified in the building (if present).

6.0 CONCLUSIONS

The results of the asbestos survey conducted at the L1995 – Hanksville Office, Richfield Field Office, Utah facility building indicate that: one (1) 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 Tetra Tech’s inspection of the L1995 – Hanksville Office building located at the Richfield Field Office, Utah.

The selection of sample locations and frequency of sampling was based on Tetra Tech’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.
