In consultation with the NRCS, we have reviewed this request for a mining permit to extract sand and
gravel as well as operate a concrete batch plant. Norntan Wells, District Conservationist, with NRCS made
att on site visit on November 29, 2001. Based ott information provided, we have the following comments
regarding this application:
I. While the plan {page 15) indicates that undisturbed areas will be managed as irziga[ed pasture or
outer appropriate crop cover, there are no signs of any of the area having been irrigated previously.
If this is the case, does the applicant own adjudicated water rights for irrigation purposes? If the
area is to be irrigated it appears that land smoothing would be necessary and that the choice of crops
will be limited due to the proximity to the water table.
2. One of [he anticipated uses indicated in the reclamation plan is for irrigation water storage. The
question of water rights would again be raised. Since the final ponds will be into and below the
water table, pumping water out; this would allow additional ground water to enter the pond to which
the owner may not be entitled
3. The reclamation plan calls for topsoil [o be placed on slopes at a maximum of 4:1. The slopes
should be a MINIMUM of 4:1 with flatter slopes being more desirable from an erosion standpoint.
Equipment becomes very unstable when working on slopes steeper than 4:1. All foreign water
should be diverted around and not allowed to run down these slopes. Topsoil should hr ripped or
o[henvise worked into the base soil to assure a good bond and [o eliminate any chances of a
hardpan developing.
4. While the seeding ntix looks adequate, it is doubtful if some of the species will survive or not. The
seeding dates should not be earlier than November I". Grass planted in September can often times
gerntina[e but not attain enough growltt prior [o the first frosting and will die. Plantings in
November will generally not germinate until the following spring.
~. Since the reclamation plan does no[ address weed control on the reclaimed portions, we would
suggest that the applicant contact Ron Broda, Vegetation Management Specialist, with Weld
County to develop a comprehensive weed management plan for the entire area. He can be reached
at 970-356-4000 ext. 3770.
