Quantitative sampling of reclaimed areas at Seneca Coal Company's (SCC) Seneca II Mine was undertaken in July and August 2006 by ESCO Associates to facilitate SCC's continuing monitoring of the progress of these areas in relation to revegetation performance standards. 2006 data collection was pursued toward the end of providing datasets adequate to allow formal testing of Revegetation Success and for use in eventual application for Phase 2 (II) and Phase 3 (III) Bond Release. Methods, sample areas, and sample sizes were those specified in a study plan submitted by SCC to Colorado Division of Minerals and Geology (ESCO 2005b). METHODS Phase 111 Bond Release Blocks For purposes of this sampling Seneca II Mine reclaimed areas planted by or before December 31, 1996 have been divided into two Bond Release Blocks (BBB's): BRB -2. This block includes land reclaimed between February 25, 1976 and September 21, 1981. These areas were subject to provisions of what may be termed "Interim" rules preceding the formal start of provisions of the Colorado Permanent Program. BRB -3. This block includes land reclaimed between September 22, 1981 and December 31, 1996. These areas were subject to provisions of the Colorado Permanent Program and are old enough to be in at least year 9 as of 2005. Both BRB-2 and BRB-3 were sampled in 2005 also along with lands mined prior to February 25, 1976 that may be termed "pre-law" lands. The results were reported in the 2006 annual report and in ESCO (2006). Phase 2 (ll) Area Sampling (BRB-4rev) Part of Seneca II reclaimed lands seeded on or after January 1, 1997 that were formerly included as part of "BRB-4" were sampled for cover to provide information that would be of use were an application for Phase 2 (II) bond release for those lands. The lands included in this sampling were henceforth refered to as "BRB-4rev". Sample points in this area are shown on Map 4. I 1
