Jared:
Thanks for forwarding Metcalf s analysis of potential effects associated with Twentymile's Wolf Creek Seam
project. Unfortunately, our office has not yet received a copy of the report titled "Peabody Sage Creek LLC: A Class
III Cultural Resource Inventory of the Sage Creek Subsidence Expansion Area, Routt County, Colorado (2013,
revised April 2015) from BLM Little Snake. And as this report appears somewhat central to Metcalf s letter and as
it may inform this consultation, I've copied Brian Naze, the Little Snake FO archaeologist, in my response. I will
also say that while Brian and I have informally discussed the possibility of baseline subsidence studies as terms of
mitigation for the Sage Creek Expansion which Metcalf recommends as worthwhile, no formal consultation has
yet occurred. Brian, what is the status of the Sage Creek consultation?

Mark,
On September 11, 2015 the Division received a letter from your office regarding the results of a cultural
resources inventory that was conducted for three revisions proposed for the Foidel Creek Mine's mining permit
(C-1982-056). The revisions included MR289, PR10 and PR11. Regarding MR289, it was found that the
project would result in no historic properties affected. For PR10 and PR11, your office requested additional
information regarding the nature and extent of potential subsidence effects on two sites (5RT3324 and
5RT3325). The Division requested the permittee (Twentymile Coal, LLC.) to conduct an analysis of
subsidence impacts to these sites. They hired Metcalf Archaeological Consultants, Inc. to conduct an
analysis. On November 4th, 2015 the Division received a letter from Metcalf Archaeological Consultants with
the results of their analysis. Their letter is attached. The Division has reviewed the analysis and concurs that
mitigation measures are not likely necessary for the sites in question. However, we request that your office
review the analysis. Please feel free to contact me with questions.
Thank you,
Jared
