George Martin of CEMEX, Inc. was present during the inspection. <br />The Dowe Flats operation mines four horizons of calcium carbonate material to use at the <br />nearby cement plant also owned by CEMEX, Inc. Material is mined with large surface <br />machinery and hauled to a nearby conveyor system where it is conveyed to the cement plant. <br />The four seams are mined from the west. The Hi-Cal bed is mined over a length of almost <br />8,000 feet and the 2°d and 3~a seams will be extracted over a distance of 5,000 feet. The <br />4`h ridge outcrop is mined over a distance of 1,9000 feet. <br />As a pit progresses, the topsoil and overburden material are stripped and topsoiled for <br />future use. According to the 2000-2001 Annual Reclamation Report Map, approximately 46 <br />acres have been reclaimed. In 2001, 10 acres were ready for seeding. A total .of 87 acres <br />are either active mining areas, or stockpile areas. <br />Portions of the reclaimed area were inspected. Considering the harsh drought conditions <br />this year, the vegetation appears to be established. Some annual weeds were noted, but <br />are expected for the first two growing seasons. The operator stated that noxious weeds <br />are sprayed once a year. <br />No problems were noted during the inspection. <br />I & E Contact Address <br />^ CE <br />NAME Mr. John Lohr ^ BL <br />OPERATOR CEMEX, Inc. ^ FS <br />STREET P.O.
