SUBJECT: Bowie No. 2 Mine, Permit No. C-96-083, Permit Revision No. 10
I have reviewed Bowie Resources, LLC (BRL's) PR-10 responses to our 8th adequacy review letter
which was sent to BRL on October 2, 2008. BRL has now adequately addressed all of our
comments. We had previously accepted the text revisions and the new cross section/fence diagram
for the Lower Perched Water Zone (Map 11-1). My review of their response to our final comments
is given below in the same numbered paragraphs as our October 2 d letter.
2A.
1. We requested that the Upper Perched Water Zone also be shown in Cross-Section. BRL
updated the text on page 2.0428 to explain that it is not possible to predict a piezometric
surface over an extensive area for the Upper Perched Water Bearing Zone. Therefore BRL
does not provide a cross-section for the Upper Perched Water Zone as explained in their
response. I noted one typo in the third to last sentence of the first paragraph of page 2.04-28
where "underling" should read "underlying".
2. BRL fully explains the significant elevation differences that I noted in my previous review
when comparing existing approved Map 11 to the proposed revised Map 11. I have no
further comments.
I believe that with these revisions to the PAP (discussing difficulty of deeper wells not
located along the Hubbard Creek drainage) and in combination with the USFS Paonia
Ranger District letter stating that it would be "highly unlikely" that BRL would be granted
access to drill a monitoring well along Hubbard Creek; it would be reasonable for the
Division to accept this as sufficient to satisfy Rule 2.04.7 and ultimately approve PR-10.
BRL has (to the best of their ability) satisfied the requirements of 2.04.7(4)(c).
Let me know if you have any questions regarding my review of BRL's latest responses.
