agronomic parameters. The analytical results will provide information relative to the
nutrient status of the topsoil material that will be spread on the mined lands. A
detailed sampling and evaluation plan will be submitted within 30 days of the final
action by the Mined Land Reclamation Board. Final approval will be obtained as
expediently as possible,however it may take more than 45 days depending on the
amount of time spent by the Division of Minerals and Geology in reviewing the soil
testing plan.
6. Regarding noxious weeds and a weed control program.
Noxious weeds create problems on both upland and bottomland area throughout
Boulder County. Canada thistle is a common weedy component of streamside and
lowland areas along major streams,like Boulder Creek and South Boulder Creek,as
well as along smaller streams and drainage ditches. The most troublesome weed
species on upland areas is diffuse knapweed. I have observed both of these species
on the reclaimed areas at the Deepe Farm Pit site,however they constitute only a
minor part of the vegetation. Also these species occur on lands adjacent to lands
included within the permit boundary. Part of the reason for the limited presence of
these species within the permit boundary is that Western Mobile currently has a weed
control program in place and regularly contracts for herbicide-based weed control. It
is my opinion that the change in the reclamation plan will not create conditions that
would make the reclaimed areas more prone to support weeds than are currently
present on the existing reclaimed lands. The existing reclaimed areas have topsoil
thicknesses within the range of 6-8 inches. The proposed change in the reclamation
plan calls for approximately 5 inches of topsoil to be spread on mined lands.
7. It is my opinion that the reclamation plan amendment will have no impact on Ute
Ladies Tresses Orchids occurring on adjacent properties; any weed problems will not
be severe and they can be addressed with current weed control technologies;the
vegetation on adjacent properties will not be impacted; and suitable controls exist to
assure that inadequate revegetation of the site will not result in the release of the
reclamation bond for the property.
