This seed mix will be used for permanent drainage channel sides and bottom. The <br /> vegetative species are mostly native. The species selected in the "Grassed waterways seed mix" are <br /> appropriate to the area, should be able to handle occasional flow in the drainage, and will help stabilize <br /> the drainage. <br /> The Division has a small concern with inclusion of Reed Canarygrass. This species has the ability to <br /> become invasive, even though it is considered native. It has been identified as a noxious weed species in <br /> the states of Washington, Massachusetts, and Connecticut (USDA Plants database). The operator is <br /> proposing to include 0.5 Ibs PLS/acre of this species. Reed Canarygrass will be a small component of the <br /> overall seed mix. After seeding GCC Energy, LLC will need to monitor the grassed waterways to assure <br /> that this species does not take over. <br /> Please let me know if you have any questions. <br /> Janet Binns <br /> Environmental Protection Specialist III <br /> Coal Regulatory Program <br /> P 303.866.3567 ext 8107 1 F 303.832.8106 <br /> 1313 Sherman St., Room 215, Denver, CO 80203 <br /> janet.binns@state.co.us I http://mining.state.co.us <br /> C 0 L 0 R A D 0 <br /> C40 <br /> aDivision of Reclamation, <br /> Mining and Safety <br /> Department of Natural Resources <br /> https://mail.google.com/mail/b/AH1 rexQlk6XcoExBXEmrSL_KTHchOwUT4S_nJAykK2RUX8CckJ4D/u/O?ik=deb7fOcd20&view=pt&search=all&permth... 1/1 <br />
