<br />Re: Battle Mountain Resources, Inc., San Luis Project; RMC Job No. 19-3754.001.00
<br />Dear Lori:
<br />Rocky Mountain Consultants, Inc. (RMC) has reviewed the September 17, 1999 document entitled
<br />"Response Actions Proposed in the West Pit Area, San Luis Project, Costilla County, Colorado."
<br />This document was prepared by Shepard Miller, Inc. (SMI) for Battle Mountain Resounces, Inc.
<br />(BMRq. RMC received this document on October 27, 1999.
<br />Of note, BMRI has apparently finally seen the wisdom of installing a slurry wall around that portion
<br />of the West Pit that connects with the Rito Seco alluvium. The slurry wall should inhik~it both the
<br />flow of clean water into the upstream end of the West Pit from the Rito Seco, and the return of
<br />contaminated water to the Rito Seco at the downstream end West Pit. This is the long-term solution
<br />to the problem that we, as a group, have been advocating since the pubiicatlon of TR-26.
<br />RMC offers the following comments and recommendations on this particular document.
<br />Section 1.0, Paee 7, Paragraph 2, Last Sentence
<br />The following documents were apparently submitted to the CDPHE on a previous occlsion, and
<br />are repeatedly referenced throughout this current document:
<br />1. TR-26 Water Management in the West Pit Area, San Luis Project, Costilla County, Colorado,
<br />dated March 22, 1999; and
<br />2. Technical Review comment Response, TR-26 Water Management in the West f'it Area, San
<br />Luis Project, Costilla County, Colorado, dated August, 1999.
<br />To our knowledge, these documents are still undergoing adequacy review by the DMC~. We, as
<br />well as other consultants to the Costilla County Conservancy District (CCCD), have numerous
<br />questions and issues concerning the adequacy of these two documents that BMRI have not
<br />addressed.
<br />Section 1.1, Pape 1, Paragraph 1, Cine 2 and Page 3, Paragraph 2, Line 3
<br />The "C" in a CDO stands for cease, not control, as in "cease the flow of groundwater from the West
<br />Pit.'
