Annual Report - Construction Materials Operation <br />Yule Quarry <br />Permit Number M-199-058 <br />Colorado Stone Quarries, Inc. <br />'!r, <br />August 2010 <br />r <br />A. Reclamation accomplished to date: <br />Sierra Minerals Corporation, previous owner of the Yule Quarry operations, established a test plot in <br />2002. The purpose of the test is to determine if it will be feasible to use existing marble fines for topsoil <br />from offsite.. <br />The test plot has demonstrated that the Permit specified grasses will grow and survive over a number of <br />years where the soils are mostly fines. This test plot was covered during construction in Fallof 2009. <br />Colorado Stone Quarries will establish and monitor a new test plot in 2010. <br />Other grasses and native plants have started growing in many other spots of the property. CSQ will <br />monitor these as well. <br />In August 2009, CSQ was directed by the Division of Reclamation to update and construct improved <br />rainfall/sediment control structures. CSQ is in the process of constructing these measures to be <br />completed by end of August 2010 (Map 8). <br />The steep northern slope outside the entrance tunnel will be vegetated and monitored along with the <br />building of 6 control structures. Initial construction has already shown improved runoff control.
