INTEROFFICE MEMORANDUM <br />TO: KENT CORHAM <br />FROM: JANET BINNS <br />SUBJECT: ItA"rON CRF, . -1982-055 <br />DATE: t/2[/2005 <br />CC: DAN FIERNANllE"l. <br />I have reviewed the 2004 Vegetation Monitoring Report for the Raton Creek Mine. IME conducted the <br />vegetation sampling and prepazed the report for Energy Fuels Coal, Inc. for the first year of sampling for final <br />bond release as per Rule 3.03.1(2) and Rule 4.15.7(5). The report was submitted to the Division for informal <br />review. <br />The mine was reclaimed in 1994 with initial seeding occurring in late fall 1995. Limited inter-seeding has <br />occurred in February 1996, May 1996, November 1999, May 2000, and seeding of pond cleaning material <br />occulted in May 2003. Vegetation sampling was conducted June 17-23, 2004 and September 4-6, 2004 to <br />coincide with peak vegetative growth and vigor. <br />Vegetation success standards aze found on Raton Mine Permit page 521 and 522. Sampling methodology is <br />described on page 522 in the PAP. Approved seed mixes for re-establishing rangeland are found on pages 524 <br />and 525 of the PAP. Cover, production and woody stem density data were all collected to sample adequacy <br />with a 90% level of confidence. <br />The approved reclamation standard for live vegetative cover is greater than or equal to 25%. Live vegetative <br />cover of all species totaled 36.87%. Removal of cover value provided by noxious species, 3.87%, and annuals <br />and biennials, 4.87%, finds "allowable" cover to be 28.13%. This value is still in excess of the 25% cover <br />reclamation success standard. Live vegetative cover is successful for the Raton Creek Mine for the 2004 <br />sampling event. IME included broom snakeweed (Guttierrezia sarothrae) cover as cover contributed by shrub <br />species. Broom snakeweed is considered asub-shrub (see enclosed data sheet from USDA-NRCS Plants <br />database). It has been the Division's practice not to count sub-shrub species as woody stems. Cover <br />contributed by sub-shrub species can be included in the forb category. <br />The approved productivity standazd for the Raton creek Mine is 300 Ibs/acre. IME collected three one-quarter <br />of a squaze meter quadrats along 68 transects for productivity determination. The three quadrats were <br />combined for each transect. IME sampled perennial grasses and forbs for inclusion in the productivity <br />determination. Annual, biennial, and noxious species were not sampled for productivity evaluation. Woody <br />plants were not sampled for inclusion in the productivity calculations either. Results of productivity sampling <br />determined that the reclaimed community produced 33.78 g/'/a MZ. This value translates to 1,203.91bs air dry <br />biomass per acre. The reclamation standard for productivity is 300 lbs air dry biomass per acre. The reclaimed <br />azea exceeded the standard in 2004 fourfold. The reclaimed area was successful for biomass production in <br />2004. <br />
