Page 4 of 7 done to break up the compaction then harrowed down. The area will then be re-seeded using an approved seed mixture. Dormant planting is possible any time after October 15t or when temperatures are cold enough to prevent seed germination. Seeding on frozen soils will be avoided. Planting may also be done in the print until the end of April or early May and between July 1st and September Pt. The recommended reclamation seeding mix of the stockpile area is the Weld County General Seed Mix for areas north of County Road 68. The seed mix is as follows: • Buffalo Grass (Taxoka, Sharps Improved) 1.5 lbs pls/acre • Little Bluestem(Blaze, Cimarron, Camper) 1.5 lbs pls/acre • Sideoats Grama(Vaughn, Butte,Niner, El Reno, Haskell) 2 lbs pls/acre • Blue Grama(Hachital, Lovington) 3.5 lbs pls/acre • Western Wheatgrass (Arriba, Barton, Rosana) 3 lbs pls/acre • Switchgrass (Nebraska 28, Blackwell) 1.5 lbs pls/acre • Perennial Ryegrass (Calibra or Garibaldi tetraploid) 0.75 lbs pls/acre • Sand Dropseed 0.25 lbs pls/acre Total: 14 pounds pls/acre Seeds will be planted immediately following completion of mining activities to decrease competition from noxious weed species. Seeds will be planted using drill seeding at the appropriate depths. A one-time application of manure/compost mix will be applied to the seeded area for stabilization and fertilization. The seeded areas will not be irrigated. Noxious Weed Management Various state and local regulations require management of noxious weeds. If established quickly, crop cover and standard farming practices will help suppress weed growth. The operator will monitor disturbed areas for noxious weeds during the mining operation. Currently, there are no noxious weeds identified on the subject property. The majority of the site has been under continuous crop cultivation. The greatest period of susceptibility for weeds to establish themselves is during temporary stockpiling and the start of reclamation procedures. Operator will survey the site regularly and monitor weed conditions. Should noxious weeds be identified, the operator will work to eradicate the weeds. Mechanical control methods such as pulling, mowing, and tilling and chemical control methods with the use of herbicides will be used. Proper identification of the suspected noxious weed will ensure the appropriate control methods are utilized. A complete list of Colorado noxious weeds can be found at https://ag.colorado.gov/conservation/noxious-weeds/species-id. If excavation activities are completed before the growing season begins, preventative measures such as spraying will be taken. Establishment of crop cover will be the most effective method of long-term weed suppression.
