INTRODUCTION <br />Quantitative sampling of reclaimed and reference areas at Seneca Property, LLC (SPL) Yoast Mine was <br />performed between August 13th through 271' in 2016 by Cedar Creek Associates, Inc. (Cedar Creek) to <br />provide data for formal testing of revegetation success in application for Phase I I Bond Release. <br />Methods, sample areas, and sample sizes were specified in a study plan submitted by SPL to Colorado <br />Division of Reclamation, Mining, and Safety (CDRMS) (2016 Scope of Work, Cedar Creek). <br />METHODS <br />Phase 11 Bond Release Block 2a Sampling <br />The 123.7 acres of the Bond Release Block 2a (BRB-2a) was assembled from reclamation parcels <br />seeded from 2002 to 2013. The 69.3 acres of the Bond Release Block 3 (BRB-3) was assembled from <br />reclamation parcels seeded in 2007 and 2010. Lands included in the BRB-2a and BRB-3 are subject to <br />the Colorado Permanent Regulatory Program (Post -Law). Sample areas and locations are shown on <br />Map 1, "2016 Vegetation Monitoring Locations - Phase II BRB-2a" and Map 2, "2016 Vegetation <br />Monitoring Locations - Phase II BRB-3 and Haul Road Reference Area." <br />Reference Area Sampling <br />The Aspen, Mountain Brush, Sagebrush and Steep Mountain Brush Extended Reference Areas (ERA) <br />were sampled to provide cover data for comparison with BRB-2a. The Haul Road Reference Area was <br />sampled to provide cover data for comparison with the BRB-3. Reference Area sampling locations are <br />shown on Map 2, "2016 Vegetation Monitoring Locations - Phase II BRB-3 and Haul Road Reference <br />Area," and Map 3, "2016 Vegetation Monitoring Locations — Extended Reference Areas." <br />
