RE: Colowyo Coal Co. L.P., (C-81-019)
Technical Revision No. 44
Additional Information, Response to Technical Adequacy 2
Dear Mr. Walker:
Attached please find information addressing modifications to our TR~4 submittal. The submittal of
this information is a result of our review of the Divisions Technical Adequacy 2 letter of April 13,
1998.
Item 1 -Notification of residences or owners of dwellings or structures located within one-half mile of
the area affected by blasting activities.
While the cited Statute does require specific notifications there is, however, no requirement for a
map as suggested by the Division. However, to address other Division concerns we have modified
the Map 26 -Blasting Pattern Alterations -Overburden and deleted Maur 27 -Blasting Pattern
Alterations -Coal from the Permit. The information contained in the revised Map 26 (now referred to
as "Blasting Analysis Map") and the modified Permit section 4.08.3 will address the issue of
notification of blasting within one-half mile of a residence. In general, this required notification
procedure will not occur at Colowyo for a couple more years due to the schedule of our mining
advances. When the time occurs for this requirement to be implemented, if no variance is provided
by applicable residents, Colowyo's procedure will be to contact the occupants of a residence no
less than 24 hours prior to an applicable blast and documentation of the notification will occur on the
specific blast report.
At this time the only applicable residence is the Durham residence which is shown on the revised
Map 26.
The Division should also be aware that Rule 4.08.4(8) is inconsistent with the applicable Statute.
While the Statute requires daily notifications (assuming this means 24 hours or less), the Rule
states that notifications are to occur "no less than 24 hours prior' to the blast. Thus, the two
statements appear to be in conflict. Please advise!
Item 2 -Rule 4.08.1(41(b) Blast Design
General Comments:
The Division states that the Colowyo Permit is apparently deficient because certain elements of
Rule 4.08.1(4)(b) are not addressed. Colowyo's interpretation of this specific Rule is that submittal
