Introduction At the request of Mr. George Patterson, General Mine Manager of Energy Fuels Coal, Inc. (EFCI) ), interim revegetation monitoring was conducted during the summer of 2010 on three different reclaimed areas located at the Southfield Mine located near Florence, Fremont County, Colorado. Revegetation monitoring was conducted on two reclaimed areas at the Southfield Mine site and at one site located at the Loadout site. At the Southfield Mine site, the Vento Reclamation and Corley Reclamation areas were sampled. All of these areas are located on the Map 1, Mine Site Reclamation found in the 2005 Annual Reclamation Report and contain a total of approximately 37.4 acres. The Vento Reclamation area consists of a total of approximately 24.4 acres and contains to five different reclamation blocks. A large reclamation block corresponding to Revegetated Area 8, located on the west end of the Refuse Pile, a small reclamation block located immediately to the west of Sediment Pond 4, a larger reclamation block located immediately to the east of Sediment Pond 4, a smaller reclamation block located near the west side of the mine portal area, immediately to the west of Fremont County Road 22 and a large reclamation block located to the east of Fremont County Road 22 and immediately to the west of the Corley Reclamation. The Corley Reclamation consists of a total of approximately 13 acres located on the eastern most portion of the old mine facilities area, in the vicinity of the previous coal stockpile and coal loadout areas. the Loadout Reclamation consists of the site corresponding to the old trainload area and is located adjacent to the Union Pacific Railroad tracks approximately one mile west of Florence and is bisected by Fremont County Road 19. The locations of theses specific reclamation blocks are depicted on the EF'C! Annual Reclamation ncpcarr Maps and are reproduced on the enclosed vegetation transect location maps. This revegetation monitoring effort was prepared with the intention of satisfying only interim revegetation monitoring requirements. Mr. Kent Crofts of IME, who has conducted numerous previous vegetation sampling efforts at the Southfield Mine, and numerous other mine sites in southern and northwest Colorado in the past 34 years, directly supervised all field investigations. Assisting in this sampling effort: was Mr. loin) Fielding, who acted as field technician. Both individuals performed all of the field sampling and data analysis. Assisting as laboratory technician in the vegetation sampling was Nits. ( ,oraine ('roits who weighted the dried plant samples and summarized the plant weights. Methods Maps, in both electronic and hard paper format of all of the reclamation blocks to be sampled in this monitoring effort were supplied by Mr. George Patterson, who also delineated in the field, the exact extent of the reclamation efforts which needed to be sampled in this revegetation monitoring effort. The specific sampling methodologies used in this evaluation are those found t
