G <br /> <br />Southwestern <br />Portland Cement <br />A Southdown Company <br />January 31, 1995 <br />Gary L. and Sharron S. <br />5617 Ute Road <br />Longmont, CO 80503 <br />RECE/VET <br />MAR <br />~ 8 1998 <br />Stratton D~V~S~0c0~rviinera~S~U°0~09Y <br />Dear Mr. and Mrs. Stratton: <br />As part of the Dowe Flats Mining Project, located in the general vicinity of your property, <br />blasting will be performed. Southwestern Portland Cement Company (SPCC) has committed <br />to a program of monitoring and surveillance of ground motion and air overpressure resulting <br />from blasting. As part of this monitoring program, pre-blast surveys will be completed for <br />properties within 2,500 feet of the mining pit boundary to document structure conditions prior <br />to commencing mining, subject to the property owners consent. While your property is <br />beyond 2,500 feet from the area subject to mining, SPCC would like to extend to you the <br />opportunity to have apre-blast survey conducted for structures on your property. <br />The pre-blast surveys will be conducted by personnel from AGRA Earth & Environmental, Inc. <br />(AGRA). The surveys will consist of observation of the condition of structures with particular <br />attention to existing structural distress such as cracks in walls and foundations. To properly <br />complete these surveys, access to both the interior and exterior of all buildings on a property <br />will be necessary. For properties supplied by on site water wells, a water sample would be <br />obtained for analytical testing and a general assessment of well production capacity will be <br />made. Documentation of the structure condition will be made by field notes and sketches and <br />photographs. A summary report will be prepared and presented to the owner of each property <br />surveyed. Originals of all documentation will be retained by SPCC. <br />You will be contacted by Darrel Buffington or Don Van Buskirk of AGRA in a few days to <br />schedule a survey of your property, with your consent..lf you.have any questions concerning <br />the procedure fer the pre-blast surveys, you Can contact MI. 6uffir,gtoa or tRr. `Jar ?uskir4_ <br />at (303) 277-9988. I will be happy to answer any other questions concerning the Dowe Flats <br />project and can be reached at (303) 823-6685. <br />Sincerely, <br />Southwestern ortland Cement Company <br />ohn Lohr <br />Plant Manager <br />Itr-b.pri <br />P.O.
