Room 215 Denver, Colorado AO'03 Phone: 130]1 abb-7567 FAx: (3031 832~a1 U6 DATE: January 14, 1999 TO: Mike Boulay FROM: Dan Mathews ~~ RE: Seneca II-W 1997 Annnual Reclamation Report Review Permit No. C-82-057 ~~~~~ DEPARTMENT OF NATURAL RESOURCES Roy Romer Governor lames 5. Lochhead E>ec Wive Director Michael B Long Dinsion Dueuor Mike, a couple months back, you gave me several Seneca II-W 1997 annual report documents to review, including Annual Reclamation Report, dated March, 1998; 1997 Reclamation Studies and Shmb Establishment Monitoring at Seneca II and Seneca II-W Mines, dated January 28, 1998; and 1997 Revegetation Monitoring Report, dated April, 1998. From review of my files, it is apparent that I have already reviewed these annual reports in association with the most recent ntid-term permit review. Please refer to my memo to you dated June 23, 1998. I identified some concems with the annual report information in that memo, and 1 assume these concems were incorporated into a ntid-temt adequacy review fetter. If we have received a response to the identified concerns, please forward a copy to nte. If we have not received a response, the operator should be reminded to address the concems in association with 1998 annual report submittal. One item of note which I did not mention in my 6/23/98 memo, is that the operator has initiated long term studies on woody plant establishment plots 95 W-I, 96W-I, and 97 W-I. 1997 was the first year of cover and woody plant density data collection on 95W-1, as it was replanted in late 1996. 1997 was also the first year of data collection for 97 W-I, and was the second year of data collection for 96 W-I. Items of note for 95 W-I were infestation of Canada thistle and high percentage of browsed shrub transplants. Some volunteer snowberry and rose were present. 96-I had relatively high survival of planted species, and low cover of noxious weeds. Browse percentage was high, though not as high as 95W-I. 97W-I had been planted only recently. Presence of several volunteer native shrub species was noted. Peabody consistently performs thorough and well thought out revege[ation monitoring a[ their Routt County mines, and has incorporated monitoring as a component of the reclamation process. Their efforts are commendable. Cc: Larry Routten DanswordUtt iscm ine~2w97anrp.mem
