EXHIBIT A <br />• • MORGAN COUNTY COMMISSIONERS <br />COMPLAINT <br />MORGAN SAND AND GRAVEL <br />DCM Science Laboratory, Inc. <br />12421 W. 49th Avenue, Unit #6 <br />Wheat Ridge, CO 80033 <br />DCM Project No.: HEM 1 <br />Client Job No.: LONGACRE RANCH <br />Bulk Sample Analysis <br />BULK SAMPLE ANALYSIS PROCEDURES: <br />Page A of -42 <br />DCM Science Laboratory, Inc. analyzes bulk asbestos samples following procedures developed by the <br />McCrone Research Institute and in compliance with guidelines established by the Environmental Protection <br />Agency. (EPA-600/R-93/116, July, 1993). <br />Bulk samples are prepared for analysis using a 10X-SOX stereo microscope in a hepa filter hood which provides <br />a contamination-free environment. The sample is then analyzed by polarized light microscopy (PLM) at 100X. <br />When the sample consists of more than one layer, each layer is prepared and analyzed separately. Fiber and <br />matrix materials are identified by the characterization of optical properties including color and pleochroism, <br />form, cleavage, relief, birefringence, extinction, orientation, twinning, interference figure and other distinguishing <br />features. Dispersion staining is also used to further aid in mineral identification. All percentages of asbestos, <br />other fibers and non-fibrous constituents are calculated from the values obtained from analyses using the <br />stereo and PLM microscopes. In-house and NIST standards as well as a chart prepared by R.D. Terry and <br />G.V. Chilinger for "The Journal of Sedimentary Petrology", (Volume 24, pp. 229-234, 1955) provide a guide for <br />estimating percentages. All samples are archived'for six months unless other arrangements are made by the <br />client. <br />ACCREDITATION: <br />DCMSL is accredited by NVLAP (since April 1, 1989). Our NVLAP Lab Code is 101258-0. DCMSL complies <br />with NVLAP requirements unless otherwise noted. <br />ENDORSEMENT: <br />The results of this analysis must not be used by the client to claim endorsement by NVLAP or any agency of the <br />U.S. Government. <br />This test report relates only to the items tested.
