New Horizon Mine <br />New Horizon Mine <br />Permit: C-1981-008 <br />2015 INTERIM REVEGETATION EVALUATION <br />1.0 INTRODUCTION <br />Cedar Creek Associates, Inc. (Cedar Creek) was contracted in 2015 by the New Horizon Mine (New <br />Horizon) to conduct interim vegetation monitoring within selected reclamation units. Monitoring was <br />performed in the interest of ascertaining progress toward revegetation success in general accordance <br />with success standards and in fulfillment of vegetation monitoring requirements for the New Horizon <br />permit. At the time of sampling, revegetation within evaluated units had experienced either 2 or 7 <br />growing seasons following completion of seeding (Section 205.4(2)(e), Section 7.0 of permit C-1981- <br />008). In general, revegetation is classified into three types at New Horizon: Irrigated Pasture, Dryland <br />Pasture, and Irrigated Cropland. As stated in the permit, reclamation units are evaluated for interim <br />revegetation performance in Years 2 and 7 at New Horizon for irrigated pastureland and dryland pasture, <br />and years 2 and 8 for irrigated cropland. It is anticipated that bond release evaluations will occur in <br />years 9 and 10 for irrigated pasture and dryland pasture reclamation and years 8, 9, and 10 for irrigated <br />cropland reclamation. <br />Held sampling for the directly measurable <br />variable of ground cover was conducted on the <br />Irrigated Pasture units and associated Irrigated <br />Pasture Reference Area in 2015. Field efforts <br />from June in through 4k', 2015 were conducted <br />under the direct supervision of Cedar Creek's <br />Senior Reclamation Ecologist and Soil Specialist, <br />Mr. Jesse H. Dillon. The units monitored during <br />the 2015 effort are presented on Table 1 and <br />exhibited on Map 1.
