Revegetation Monitoring <br />The success of planted and seeded vegetation will be monitored <br />biennially after initial planting and seeding. Monitoring will consist of <br />qualitative and quantitative vegetation sampling techniques that <br />measure the vegetation cover, species diversity and the survival of plant <br />species within the revegetated areas. <br />Revegetation Sampling Methods <br />Revegetation sampling methods employed to measure the success of <br />revegetation at the King II Mine will comply with those specified by the <br />regulatory authority at the time of revegetation monitoring and bond <br />release. Currently CDRMS Rule 4.15.11 specifies methods for use in <br />vegetation sampling. Any of those specified methods may be employed at <br />the King II Mine for vegetation sampling. <br />Revegetation Success Criteria <br />In consultation with the Colorado Division of Reclamation, Mining and <br />Safety (Division) in 2005, the big sage mixed shrubland community was <br />delineated and quantitatively sampled. The Division agreed that a <br />segment of that vegetation community (located outside the surface <br />facilities disturbed area) would be utilized as a reference area for <br />revegetation success determinations. Since the reference area was a <br />subset of the vegetation community quantitatively sampled, there was no <br />need for a separate statistical evaluation. The location of the reference <br />area is portrayed on the Soils, Vegetation 8v Land Use Map, King II -006. <br />The reference area is signed to prohibit unauthorized access, however it <br />is not fenced, providing access to wildlife. <br />The reference area will serve to provide revegetation success criteria for <br />total vegetation cover and total herbaceous production. These <br />parameters will be sampled during the same season and in the same <br />manner as the revegetated area to establish the success criteria for total <br />vegetation cover and total herbaceous production at the time of <br />revegetation sampling for monitoring or bond release. <br />GCC Energy, LLC King II Mine <br />Section 2.05.4 <br />Page 15 April 30, 2015 <br />
