Adequacy response 02 Permit# M-2017-032
If the Applicant wishes not to commit to armoring pond shorelines at this time, then
please remove all language from the mining and reclamation plans referring to this
activity. the reclamation plan could always be revised in the future to incorporate this
activity, by submittal of a Technical Revision.
All language describing armoring or placement of inert fill has been removed from the
Mining and Reclamation Plans as you suggest.
Please note, if the Applicant chooses not to stabilize pond shorelines with riprap/concrete
rubble, the reclamation plan must include retopsoiling and revegetating pond shorelines,
and costs for these tasks must be included in the Exhibit L reclamation bond estimate.
This has been corrected in the Reclamation Plan so that only the 3.82 acres ± of Industrial
Area in the Old Plant Site area will be graded and left as parking area. Please see the
response to 5 above for more detail.
Exhibit F—Reclamation Plan Map (Rule 6.4.6):
8) The reclamation plan maps provided for the two proposed options do not correlate with
the mining plan maps for the two options. Based on the mining plan maps, Option 1
would consist of leaving the northeastern pre-law area undisturbed and a smaller pond,
while Option 2 would consist of mining through the northeastern pre-law area and leaving
a larger pond. However, the reclamation plan maps are labeled the opposite, with Option
2 leaving the northeastern pre-law area undisturbed. Please correct the reclamation plan
map labels so the two options correlate with the options shown in the mining plan maps.
I have changed the Reclamation Plan Maps to correspond with the Mining Plan Maps.
Option 1 is to mine the entire pre-law areas and much of the plant site. Option 2 is to
leave the northeast pre-law area undisturbed.
9) As mentioned previously, pond shorelines must either be retopsoiled and revegetated for
reclamation or stabilized by some other method such as armoring with riprap. Only the
proposed swim area with 5H:1 V slope gradients may remain as a sandy beach with no
revegetation. Please be sure this is indicated on the reclamation plan maps, showing
shorelines that will be either retopsoiled and revegetated or armored with riprap.
Thank you for the reminder, the plan was changed to resoil and seed any areas where
mining will create new lake shore.
Exhibit G—Water Information (Rule 6.4.7):
10) The Applicant has submitted a copy of the current Substitute Water Supply Plan (SWSP)
in place by Valco, Inc. to cover all post-1981 exposed groundwater for the Rocky Ford
