MINOR REVISION NO. 41
With this Minor Revision No. 41, Coors Energy Company (CEC) proposes to modify
portions of the text of Permit (C-1981-028) for the Keenesburg Mine operation, in
response to the 2004 Mid-term Review evaluation, performed by the Division of
Minerals and Geology (Division). The purpose of these changes is to bring the Permit
into compliance with the current rules and regulations relative to coal mine/reclamation
operations. Changes requested as part of this minor revision are related to the water
monitoring wells, air permitting, property ownership updates, and site plan drawings.
First, there has been a further change with respect to "Director and Officers" for Coors
Energy Company. Attached is a revised page 4b that will provide the most up-to-date
information.
Then, to the extent that it reflects property ownership and the identity of neighbors to the
Keenesburg Mine operation, CEC submits revisions to pages 3, 4 and 14 of the Permit
text, and an updated Appendix A-3 map to identify, "Adjacent Property Owners Within
One Mile of the Keenesburg Mine Permit Area". These documents will update the
changes in identity of the property owners that have occurred since the last submittal.
In so far as air permit documentation is concerned, CEC is submitting a changed page
124 for the Permit. This change of reference will make the information in Section
2.05.6(1) consistent within the Permit with respect to Air Permits versus Air Pollution
Emission Notices (APEN's). A further small change on this page updates the text with
respect to 2.05.6(2,D) by deleting the reference to a no longer existing structure.
At the Division's suggestion, CEC is providing a copy of drawing KM-4-17. This
document was removed from the Permit during a previous review, and is being reinstated
as Appendix O-3 in view of its value to the determination of reclamation cost estimates.
A revised Appendix O is also provided.
With respect to the water quality monitoring program at the Keenesburg operation, CEC
has modified the data on page 57a of the Permit to provide further background
information (casing diameter, hole depth and casing standup dimensions) for each of the
monitoring wells.
In addition, CEC concurs with the Division's suggestion that well completion (and
abandonment) information should reside in an appendix, attached to the Permit. To this
end available copies of the well information for the six (6) monitoring wells (AMW-1,
AMW-2, DH-96, DH-122, FPW and SMW-2), for the remaining water supply well
(Permit #048289-F) and for the two previous water supply wells which have been
abandoned (Permits #24650-F and #24651-F) aze presented for inclusion at Appendix I-3.
[Note: Pages 57c through 57f have been moved to Appendix I-3, and page 57b has been
modified to reflect this change.] Further, a change has been made to page 114c, to include
