RE: Adequacy Review, 83rd Joint Venture Resource, M-92-069
Dear Mr. Tuttle:
The following comments address your response letter and enclosures dated
October 1, 1992.
I find all owners represented by number and by boundary except Nos. 7 (Larsen)
and 15 (Evans).
Additional tree and shrub planting information listed on the new map lists tamarix.
Planting this small tree or shrub along watercourses or lake shores can create
management problems as the tamarix is a phreatophyte that establishes itself easily
and rapidly. Stands can be difficult to control. The Division is requesting that
tamarix not be included in the tree/shrub list. Also, to ensure diversity, the Division
requests from the Operator a commitment that not more than 30°~ of the total
number of trees and shrubs be of any one species.
2. The Division is requiring agreements with the two homeowners on the west and
east ends of the permit along F Street unless the Operator makes a commitment
that all mining activities (including stockpiles) be no closer than 25 feet to
dwellings, fences, powerpoles etc. and that the pit be no closer than 200 feet to
any of these structures. Please also indicate how these distances will be marked in
the field to ensure compliance.
3. (a) Upon approval by Weld County, please submit a copy of the approval for a
25 foot setback from the right-of-way of F Street.
(b) Compensation agreements between the Operator and Bellweather, Colorado
and Southern Railroad, and the overhead utility company are required unless
the Division receives an engineering stability analysis that demonstrates the
mining activity will not adversely affect the stability of their structures. This
certification should include appropriate soil testing and shall consider worst
case scenario such as maximum highwall, pit full of water, possible hydraulic
pressure from outside the pit, loaded trains, etc.
