Dear Mr. Hart: Cardno ATC is pleased to submit the attached Asbestos-Containing Materials Survey report for the above-referenced site. This report includes the scope of work, procedures and methodologies, tables, figures, and analytical laboratory results for the survey. Cardno ATC appreciates the opportunity to perform these services for Department of Military and Veterans Affairs (DMVA) and we look forward to working with you in the future. In the meantime if you have questions or comments regarding the information in this report or if we can be of further assistance please do not hesitate to contact the Cardno ATC Centennial, Colorado office at (303) 799-6100. Sincerely, Cardno ATC

The purpose of this project was to conduct an Asbestos-Containing Materials (ACM) survey to
identify ACM’s that may be present in the Armory Building located at 1512 Main Street,
Longmont, Colorado. Cardno ATC provided the services as outlined below:
Conduct a comprehensive asbestos survey of the identified building, which includes the
following:
1. Coordinated access to the buildings on an agreed upon schedule; 2. Survey the building to locate suspect asbestos-containing materials (ACM’s); 3. Collected representative samples of suspect asbestos containing building materials
following ASTM and EPA procedures; 4. Based on the site walk conducted on September 10, 2014, the building consists of a
single story metal framed building with a slab on grade foundation; 5. All inspectors will be accompanied by the building owner’s representative, unless
otherwise specified; 6. Suspect ACM samples were analyzed by Polarized Light Microscopy (PLM) in
Cardno ATC’s NVLAP/AIHA Accredited Laboratory located in Centennial, CO; 7. Collected all samples in a manner designed to create minimum disturbance. Cardno
ATC repaired any visible damage that was the result of the sampling efforts.
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.
These samples were analyzed by layers. Specific layer or component asbestos content is indicated when relevant. The EPA considers a material to be asbestos containing only if it contains more than one percent asbestos by Calibrated Visual Area Estimation (CVAE). EPA regulations also indicate that Regulated Asbestos Containing Materials (RACM) -- materials which are friable or may become friable -- be further analyzed by point counting when the results indicate less than ten percent asbestos by CVAE. Our laboratory utilizes CVAE on a routine basis and does not include point counting unless specifically requested. The results may not be reproduced except in full, and should not be used as a scope of work for abatement without consulting with Cardno ATC.

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