The analysis was performed by standard EPA methods. Please note the comments on page 3 of the report. The attached report presents the pertinent information used to calculate airborne fiber concentrations. The concentrations do not represent blank-corrected values. We have relied on air volumes supplied by your staff in calculating airborne fiber concentrations. These results are submitted pursuant to RJ Lee Group's current terms and conditions of sale, including the company's standard warranty and limitation of liability provisions and no responsibility or liability is assumed for the manner in which the results are used or interpreted. Unless notified in writing to return the samples from this job, RJ Lee Group will store the samples for a period of ninety (90) days before discarding. A shipping and handling fee may be assessed for the return of any samples. If you have any questions on this report or if we can be of further assistance, please do not hesitate to call us. We appreciate the opportunity to provide you with these analytical services. Sincerely yours. Thomas V. Dagenhart, M.S. Lab Manager Enclosures Monroeville. PA Berkeley. CA Washington. D.C. Raleigh.
