No additional clearing <br />or topsoil removal was necessary to maintain production throughout the year. <br />Reclamation efforts continued in the old mine area during the year with back <br />filling and re-grading of highwalls mined prior to 1990. Reclamation was completed on <br />an additional 0.5 acres with topsoil and seeding. <br />The portion of Eagle County Road #51 which serves as a haul road was treated <br />with a lignosite dust suppressant as per BLM Plan of Operations #CO-078-0-3P. Road <br />base material was replaced on worn areas of the road at that time. A project to widen and <br />raise the section of mine haul road intersecting the county road was partially completed. <br />Culvert was installed and bedded to allow for road widening. The project will be <br />completed in 2000 by raising the existing haul road grade and widening the road across <br />the new culvert section. <br />Approximately 455,000 tons of gypsum rock were shipped from the mine during <br />1999. <br />3 <br />
