NESHAP NON-REGULATED

ASBESTOS-CONTAINING MATERIAL (N-R-ACM)

1. > 1% asbestos

2. Category I Non-friable (cannot be crumbled, pulverized, or reduced to powder by hand pressure)

ACM with >1% asbestos by new PLM procedure

Packings

X Gaskets

X Asphalt roofing products

3. Category II Non-friable ACM with >1% asbestos by new PLM procedure (Category includes items meeting Category I definition but not specifically listed in that category)

X Asbestos cement materials (TransiteTM)* (Fume hoods, Welding Panels, Wall Panels)

X Asphalt, tar and rubber-base ACM products other than roofing products*

X Non-asphalt and non-paper roofing products*

Paint* (Silver Paint Sealant)

Fire brick and/or mortar*

X Sink undercoating (solid)* (Sinks and Drinking Fountains)

X Mastic for floor tile, ceiling tile, cove molding, etc.*

X Other* (Fire Rated Door/Frame, etc)

Notes:

1. (*) Denotes R&R’s interpretation of materials included in this category.

2. New PLM procedure is outlined in Appendix A, Subpart F, 40 CFR, Part 783, Section 1, Polarized Light Microscopy.

3. The Environmental Protection Agency (EPA) National Emission Standard for Hazardous Air

Pollutants (NESHAP) asbestos revision as outlined in 40 CFR, Part 61, became effective

November 20, 1990. The asbestos classification system outlined in the revision and included in this section is dynamic in nature. Asbestos materials classified as “NON-REGULATED” at the time of the survey may become “REGULATED” due to ongoing or planned maintenance, renovation, or demolition actions, which can transform a material containing greater than 1% asbestos from a “non-friable” and NON-REGULATED to a friable and REGULATED condition.

Classification of ACM in this section and in the executive summary of this report is, therefore, based on the observations of the surveyor at the time of the survey and may or may not be appropriate at later dates.

4. Maintenance, renovation, demolition, weathering, normal wear, water, or other damage can alter the “NON-REGULATED” status of materials, and necessitate precautions required for handling them as “REGULATED” asbestos-materials.

3.0 SAMPLING METHODS

Survey procedures were based on those outlined in Title 40 Code of Federal Regulation (CFR)

Part 763, USEPA Asbestos Hazard Emergency Response Act, and the Asbestos Model

Accreditation Plan (effective April 4, 1994). The procedures included visual observation, physical inspection, bulk sample collection, and condition assessment of suspect ACM. The number of samples collected was based on the amount and accessibility of each homogeneous material, with consideration given for the type, age, and condition.

Three-hundred ten (310) samples were collected from the suspect materials to assess the presence of asbestos (or lack thereof) in building materials/systems. Each sample collected was placed into a sealable plastic bag or tub, marked with a unique sample identification code, and packaged for subsequent shipment to the laboratory for analysis. Individual sample identification consisted of a numeric code denoting the sampling media/location.

After packaging and labeling, samples were submitted under proper chain-of-custody to

Reservoirs Environmental, Inc., Denver, Colorado. The National Voluntary Laboratory

Accreditation Program (NVLAP), Lab Code 101896 accredits Reservoirs for asbestos analysis.

Samples were analyzed via Polarized Light Microscopy (PLM) utilizing EPA Method 600/M4-

82-020. Please note that USEPA and OSHA regulations define an ACM as a material containing more than one (1) percent asbestos, by volume, as determined by PLM analysis. In the case of multi-layer systems (e.g., floor tile/mastic layers), the laboratory analyzed and reported each layer separately.

4.0 SURVEY RESULTS

Three-hundred ten (310) representative samples submitted for analytical determination. A summary of analytical results for samples collected and analyzed for this survey are in Appendix

B (Laboratory Results) and are discussed below by building material/system type. Photographs of the buildings where samples were taken are included as Appendix C. Floor Plans of the building where samples were taken are included in Appendix D

5.0 CONCLUSIONS

Asbestos-containing materials were identified in the building. See Executive Summary for details.

6.0 LIMITATIONS AND EXCLUSION OF WARRANTY

This asbestos survey and assessment was performed using procedures and a level of diligence typically exercised by professional consultants performing similar services. However, asbestos-containing material (ACM) can be present in a structure, but not identified using ordinary investigative procedures.

No asbestos survey can completely, eliminate uncertainty regarding the presence of ACM.

R&R Environmental, Inc.’s level of diligence and investigative procedures are intended to reduce, but not eliminate, potential uncertainty regarding the presence of ACM. The procedures used for this survey attempt to establish a balance between the competing goals of limiting investigative costs, time, and building damage, and reducing the uncertainty about unknown conditions. Therefore, the determinations in this report should not be construed as a guarantee that all ACM present in the subject property has been included in this report.

This report presents R&R Environmental, Inc.’s professional determinations, which are dependent upon information obtained during performance of consulting services. R&R

Environmental, Inc. assumes no responsibility for omissions or errors resulting from inaccurate information provided by sources outside of R&R Environmental, Inc.

No warranty or guarantee, expressed or implied, is made regarding the findings, conclusions, or recommendations contained in this report. The limitations presented above supersede the requirements or provisions of all other contracts or scopes of work, implied, or otherwise, except stated or acknowledged herein.
