Mulberry St, Unit C, Fort Collins CO 80524 (970) 266-8000 (970) 266-0022 (Fax) www.centuryenvironmental.com October 28, 2011 Original report date October 25, 2011 Q Imago Enterprises Inc Mr. Les Kaplan 140 Palmer Dr Fort Collins, CO 80525 Re: Asbestos Air Clearance Test @ 1801 S. College, Fort Collins, CO CEH Project No.: 3357.11 Dear Mr. Kaplan: The following report serves to document our final air clearance after asbestos abatement in the building located at 1801 S. College, Fort Collins, CO in accordance with Colorado Regulation 8, and USEPA requirements of the Asbestos Hazard Emergency Response Act (AHERA), if applicable. The clearance test was performed on October 24, 2011 by Patrick, Kelly, a Colorado licensed Air Monitoring Specialist (CDPHE # 2514), after Colorado Mold and Asbestos performed abatement of approximately 1200 square feet of popcorn ceiling texture located in the "Original building, Showroom, east of former partition wall." Note: a very small amount of popcorn ceiling texture was observed in concrete pits in the ceiling that was unable to be removed. CEH and the building owner, Mr. Les Kaplan, agreed that this material will be left in place. The small amount of asbestos remaining in the work area will not present an exposure issue to contractors during construction or to occupants during subsequent use of the building. A visual inspection following the "Standard Practice for Visual Inspection of Asbestos Abatement Projects" (ASTM 1368) was first performed. Any residual dust or debris noted from the abatement work (if any) was re -cleaned by the abatement contractor. Subsequently, settled dust in the work area was re -entrained using the standard method for abatement clearance, consisting of re -entraining air with a leaf blower and setting up box fans to keep air moving throughout the test ("aggressive air sampling as required by Colorado Regulation 8"). Five air samples were then collected inside the work area following the sampling provisions of the applicable test method, NIOSH 7400. The samples were handled in accordance with the method, including appropriate chain of custody. The samples were subsequently analyzed following the analytical aspects of NIOSH 7400, using optical microscopy (phase contrast microscopy (PCM) by a CEH analyst. This method is the approved method for clearance testing under Colorado Regulation 8. The PCM method detects all fiber types and does not differentiate between fibers, provided they meet the size and shape definitions. Thus, the result is a total fiber count, inclusive of asbestos, fiberglass, cellulose and other fiber -like particles, so the count does not imply asbestos was necessarily present. The CEH laboratory is currently and historically proficient in the American Industrial Hygiene Association's Proficiency Analytical Testing Program for PCM analysis and meets the requirements of 763.90 (�)(2)(►�)• The results for the final air clearance were all below 0.01 fibers/cc, the required air quality standard (MAAL) after asbestos abatement projects cleared by PCM. If you have any questions, please let me know.
