Renovation Specific Asbestos Sampling Report Primrose Art Studio 4300 West County Road 50, Larimer County, Colorado WALSH Project No. 7315-010 INTRODUCTION Walsh Environmental Scientists and Engineers, LLC (WALSH) was contracted to perform a renovation specific inspection for asbestos at 4300 West County Road 50 in Larimer County, Colorado. The inspection, limited in scope and purpose, was conducted to assess materials that will be disturbed during a planned renovation of the art studio building and demolition of the small shop. The field work was conducted on February 21, 2007. The scope of work of the inspection consisted of a visual assessment and collecting bulk samples of suspect building materials and limited reporting. ASBESTOS SAMPLING METHODOLOGY The collection of samples was performed by Asbestos Hazard Emergency Response Act (AHERA) and State of Colorado accredited building inspectors. WALSH collected bulk samples of suspect materials in a random and representative manner, as determined by the inspector. Samples were collected by obtaining a sample that included all layers within the suspect material. Each sample was collected using hand tools such as a razor knife, screwdriver or pliers, and immediately placed within a sealed sampling container and labeled with a unique identification number. Each suspect material was identified and catalogued on field sampling worksheets, the primary working document. Upon completion of collection of samples, the numerical identification information was transcribed to a chain -of - custody document to accompany samples during transport to the laboratory.

Steve White City of Fort Collins lvfarch 5, 2007 Page 2 of 3 The bulk samples were submitted for analyses to Reservoirs Environmental, Inc. a National Voluntary Lab Accreditation Program (NVLAP) accredited laboratory. Analysis of the bulk samples was perfonned using polarized light microscopy (PLM) using procedures developed by McCrone Research Institute and in compliance with the guidelines established by the United States Environmental Protection Agency (USEPA) (USEPA-600/M4-82-020, 1982) to determine asbestos type and content. The PLM analytical results are reported as percent asbestos by weight. Percent asbestos for separate Payers and total for the sample are delineated in the laboratory report. Unused portions of samples are archived for six months unless the client requests special handling. ASBESTOS FINDINGS Fourteen (14) samples were collected from six (6) suspect building materials identified in the area of the buildings scheduled for renovation/demolition. Samples were submitted to the accredited laboratory for PLM analysis. A total of fourteen (14) samples were analyzed by PLM analysis. One homogenous material, three (3) samples that were analyzed by PLM methods were further analyzed utilizing the confirmatory point count analytical techniques. The USEPA, Colorado Department of Public Health and Environment (CDPHE), and United States Department of Labor -Occupational Safety and Health Administration (OSHA) define asbestos containing material (ACM) as material containing more than one percent asbestos or a material that is assumed to contain asbestos. Three (3) suspect building materials were found to contain greater than one percent asbestos. The following table summarizes information regarding the confirmed ACM found as a result of the inspection.

LLC m:: ecolori and environment comranv Mr. Steve White City of Fort Collins March 5, 2007 Page 3 of'3 REGULATORY COMPLIANCE ACM identified in this report is subject to the USEPA National Emissions Standards for Hazardous Air Pollutants (NESHAP) and the CDPHE regulations. In addition, ACM is subject to OSHA Standards for Asbestos. Materials containing a trace amount of asbestos may be subject to OSHA regulations if air concentrations are at or above the permissible exposure limit (PEL) of 0.1 f/cc or the excursion limit (EL) of 1.0 f/cc. RECOMMENDATIONS Under renovation and/or demolition, any activity that directly impacts or disturbs ACM must comply with requirements set forth in the Federal and State regulations and applicable OSHA standards. For renovation and/or demolition activities that impact ACM, all friable and non - friable ACM that will be rendered friable must be properly removed prior to renovation activities in accordance with applicable regulations. LIMITATIONS WALSH perfonned these services in a manner consistent with the level of care and expertise exercised by members of the asbestos inspection profession. WALSH does not imply or guarantee that every potential ACM on or in the structure has been identified or sampled. This inspection was limited to the sampling locations described above. No other sampling or analyses were conducted during this investigation. It is possible that asbestos exists in areas that were not assessed during this inspection. Historically, asbestos has been added as a component to over three thousand materials and products produced in the United States. The inspection was intended to identify those accessible materials that were reasonably suspect and that were most likely to contain asbestos in quantities subject to regulation, based on existing industry and regulatory standards.
