II. Executive Summary

On March 2, 2012, Mr. Jacob Borchin and Mr. Michael J. Reeder, who are representatives of the Federal Occupational Health (FOH) on behalf of the General Services Administration (GSA), conducted an asbestos survey of the USBS Coburn Gore located at State Route 27 in Coburn Gore, Maine (Site).

The purpose of this assessment was to determine if asbestos containing material (ACM) is present at the Site by collecting non‐destructive samples of accessible suspect ACM throughout the interior of the Site.

The exterior of the Site was not evaluated as part of this survey. Additionally, historic asbestos inspection report(s) or drawings and specifications for original construction and renovation regarding the installation of suspect ACM were not provided or available when the inspectors were conducting the asbestos survey at the Site.

During the collection of suspect ACM samples, the FOH representatives implemented controls, techniques, and protocols to minimize occupational exposure to asbestos, which are in accordance with the New Hampshire Department of Health and other applicable laws and regulations. All sampling and analysis of the suspect ACMs were performed in accordance with applicable requirements by qualified FOH inspectors and by laboratories accredited by the EPA.

During the course of the asbestos survey, FOH asbestos inspector(s) were accompanied by:

Mr. Lyndon Millet, GSA Building Manager and/or designated representative.

The FOH asbestos inspectors collected a total of sixty (60) individual suspected ACM samples throughout accessible areas of the Site. According to analytical results (Appendix B), asbestos was identified in twenty‐seven (27) of the sixty samples collected. The ACMs and associated quantities identified at the Site are summarized in the following Table 1:

III. Introduction and Background

According to supplied information, the Site includes an approximate 122,807‐square foot; five‐story building with a penthouse and basement.

IV. Project Tasks

Project tasks included:

Reviewing existing drawings and specifications provided by the GSA for original construction and renovation information (as available) regarding the installation of suspect ACM.

Reviewing historic asbestos inspection reports (as available) to determine the existence of previously identified homogeneous areas (HAs) at each functional space.

Verify if previously conducted asbestos inspection was performed in accordance with the Asbestos Hazard Emergency Response Act (AHERA) regulations. If not, the number of additional bulk samples necessary for compliance with the AHERA regulations will be calculated.

Developing sampling protocols in accordance to AHERA regulations.

Sampling and analyzing various interior building materials to determine if ACMs are present.

Developing maps for each floor showing areas where suspect ACM samples were collected and ACM was identified.

Note all areas identified as inaccessible (e.g., pipe chases, wall voids, elevator shafts, locked doors, etc.) during the sampling event.

Asbestos bulk samples of various building materials and surfaces were collected at the Site and submitted to the FOH Denver Asbestos Laboratory to undergo Polarized Light Microscopy with Dispersion Staining (PLM/DS) analysis in accordance with the “Method for the Determination of Asbestos in Bulk Building Materials” (US EPA Method 600/R‐93/116, July 1993).

V. Sample Locations & Sample Analysis

FOH’s accredited asbestos inspectors conducted the survey and collected samples of suspected ACM in general accordance with the Environmental Protection Agency’s (EPA’s) interpretations and guidelines of AHERA. The inspectors surveyed the Site and collected samples of all suspected ACM. The PLM analytical data of asbestos samples collected at the Site is summarized in Table 2.

VI. ACM Condition Assessment

The FOH asbestos inspector(s) categorized the various suspect ACMs (Surfacing Material, Miscellaneous

Material, and Thermal System Insulation) collected at the Site by visual inspection and classified these materials by referencing the following definitions:

Surfacing and Miscellaneous Material

Good Condition (GC) – Material with no visible damage or deterioration, or showing only very limited damage or deterioration.

Damaged (D) – The surface is crumbling, blistered, water‐stained, gouged, marred or otherwise abraded over less than one‐tenth (1/10) of the surface if the damage is evenly distributed (one‐quarter if the damage is localized).

Significantly Damaged (SG) – The surface is crumbling or blistered over at least 1/10 of the surface if the damaged is evenly distributed (one‐quarter if the damage is localized); 1/10

(one‐quarter, if localized) of material hanging from surface, deteriorated, or showing adhesive failure; and/or water stains, gouges, or mars over at least 1/10 of the surface if the damage is evenly distributed (one‐quarter if the damage is localized).

AHERA Definition of Damaged Friable Surfacing Miscellaneous ACM:

“Friable surfacing miscellaneous ACM, which has deteriorated or sustained physical injury such that the internal structure (cohesion) of the material is inadequate or, if applicable, which has delaminated such that the bond to the substrate (adhesion) is adequate or which for any other reason lacks fiber cohesion or adhesion qualities. Such damage or deterioration may be illustrated by the separation of ACM into layers; separation of ACM from the substrate; flaking, blistering, or crumbling of ACM surface; water damage; significant or repeated water stains, scrapes, gouges, mars or other signs of physical injury on the ACM. Asbestos debris originating from the ACBM in question may also indicate damage.”

Thermal System Insulation

Good Condition (GC) – Material with no visible damage or deterioration, or showing only very limited damage or deterioration.

Damaged (D) – A few water stains or less than 1/10 of insulation with missing jackets and/or crushed insulation or water stains, gouges, punctures, or mars on up to 1/10 of the insulation if the damage is evenly distributed (or up to one‐quarter if the damaged is localized).

Significantly Damaged (SG) – Missing jackets on at least 1/10 of the piping or equipment and/or crushed or heavily gouged or punctured insulation on at least 1/10 of pipe runs/risers, boiler, tank, duct, etc., if the damage is evenly distributed (or up to one‐quarter if the damaged is localized).

Note: Accumulation of powder, dust, or debris similar in appearance to the suspect material on surfaces beneath the pipe/boiler/tank/duct, etc. can be used as confirmatory evidence.

AHERA Definition of Damaged or Significantly Damaged Thermal System Insulation:

“Thermal system insulation ACM on pipes, boilers, tanks, ducts, and other thermal system insulation equipment which has lost its structural integrity, or its covering, in whole or in part, is crushed, water‐ stained, gouged, punctured, missing, or not intact such that is not able to contain fibers. Damage may be further illustrated by occasional punctures, gouges, or other signs of physical injury to ACM;

occasional water damage on the protective coverings/jackets; or exposed ACM ends or joints. Asbestos debris, originating from the ACBM in question may also indicate damage.”

* Considered Homogenous to Previous Identified ACM.

The FOH asbestos inspector(s) also determined the ACMs potential for contact, the influence of vibration, and the potential for air erosion by referencing the following definitions:

Potential for Contact with the Material

High: Service workers work in the vicinity of the material more than once per week, or

The material is in a public area (e.g., hallway, corridor, auditorium) and accessible to building occupants.

Moderate: Service workers work in the vicinity of the material once per month to once per week, or

The material is in a room or office and accessible to the occupants.

Low: Service workers work in the vicinity of the material less than once per month, or

The material is visible but not within reach of building occupants.

Influence of Vibration

High: Loud motors or engines present (e.g., some fan rooms), or

Intrusive noises or easily sensed vibrations (e.g., major airports, a major highway).

Moderate: Motors or engines present but not obtrusive (e.g., ducts vibrating but no fan in the area), or

Occasional loud sounds (e.g., a music room)

Low/None: None of the above.

Potential for Air Erosion

High: High velocity air (e.g., elevator shaft, fan room).

Moderate: Noticeable movement of air (e.g., air shaft, ventilator air stream).

Low/None: None of the above.

VII. Sampling Protocol

Asbestos Sample Collection

Representative bulk samples of suspect asbestos containing building materials (ACMBs) were collected at the Site building. The building was divided into separate and distinct project areas. For the purpose of this survey, each area was inspected and sampled as a separate functional space having separate and distinct homogenous materials. Homogenous material determination was based on the following criteria:

Similar physical characteristics (same color and texture, etc.)

Application (sprayed‐on, troweled‐on, assembly into a system etc.)

Material function (thermal insulation, floor tile, wallboard system etc.)

Samples of suspected ACM were collected and placed into sealed plastic bags and shipped via overnight delivery to the FOH Denver Asbestos Laboratory to undergo PLM/DS analysis in accordance with the

“Method for the Determination of Asbestos in Bulk Building Materials” (US EPA Method 600/R‐93/116, July 1993).

VIII. Analytical Methods

Asbestos Samples

Polarized Light Microscopy Analysis Methodology

The FOH Denver Asbestos Laboratory, which is a National Voluntary Laboratory Accreditation Program certified laboratory, provided the asbestos analytical services. The laboratory analyzed the suspected

ACM by PLM utilizing the EPAs Test Methods: Methods for the determination of Asbestos in Bulk

Building Materials (EPA 600/R‐93/116, July 1993) and the McCrone Research Institute’s The Asbestos

Particle Atlas as method references. Additional treatment and tests may be required to accurately define the sample composition (i.e. ashing, extraction, acetone treatment, and transmission electron microscopy).

The sample analysis was performed by using the bulk sample for visual observation and slide preparation(s) for microscopic examination and identification. The lab analyzed the samples for asbestos (chrysotile, amosite, crocidolite, anthophyllite, and actinolite/tremolite), fibrous non‐asbestos constituents (mineral wool, cellulose, etc.) and non‐fibrous constituents. Using a stereoscope, the microscopist visually estimated relative amounts of each constituent by determining the volume of each constituent in proportion to the total volume of the sample.

IX. Waste Management

FOH representatives did not generate any waste material while conducting the asbestos survey at the

Site. The small amount of material collected while conducting these surveys was submitted to the laboratories for analysis, and there was no excess amount of material left that required disposal.

X. Record Keeping

In order to document the progress of this project, the FOH inspector maintained field notes, developed site sketches, and made notations on site diagrams and floor plans as the fieldwork progressed. Copies of the certified laboratory asbestos analytical reports and chain–of‐custodies are included in Appendix

A. Photos of the suspected ACM are included in Appendix B. Copies of asbestos sample locations are included in Appendix C and company certifications and inspector licenses are included in Appendix D.

XI. Summary and Recommendations

On March 2, 2012 FOH inspectors collected a total of sixty (60) individual suspected ACM samples at the

Site. Analytical results of the asbestos samples collected indicated that twenty‐seven (27) of the sixty suspected ACM samples contained at least one percent or more of asbestos. ACM identified at the Site include the following materials, which are defined and quantified in Table 1 and Table 2 of this report:

Sheetrock & Joint Compound/Paint

TSI Pipe Insulation

9” X 9” Tan Floor Tile W/ Black Mastic

Since asbestos was identified in concentrations greater than one percent, any construction or renovation activities performed in the future are subject to applicable rules and regulation concerning the disturbance or removal of the ACM. The Maine Depart of Environmental Protection rules apply to all buildings which are subject to public occupancy, or to which the general public has access. Any person disturbing, removing, or encapsulating asbestos in any public building including, renovation, dismantling, or demolition, shall notify the Maine Depart of Environmental Protection in writing ten (10) working days prior to the start date of the abatement project. It is the responsibility of the building

Owner or it’s Representative to ensure that only current Maine State license asbestos abatement companies and workers engage in asbestos related activities.

The U.S. EPA regulations do not require removal of asbestos‐containing materials that are in good condition. However, personnel who may be involved with building renovations will need to be advised of the presence of asbestos, and appropriate measures may be warranted in order to assure the identified ACM in the building are not disturbed during renovation activities. If the ACM left in place is disturbed during renovation activities, the materials must be handled and disposed of in accordance with the applicable State and Federal regulations.
