Re: M-1977-317 Cedar Wood Clay Mine, Conversion Application Adequacy.
Dear Mr. Gagliano:
COLORADO

RECLAMATION
MINING
SAFETY
The Division of Reclamation Mining and Safety has reviewed your conversion application for the Cedar Wood clay
mine, Permit # M-1977-317, from the current 110 permit covering 9.9 acres to a Phased 112 permit covering 93.25
acres, The conversion application proposes to add 83.35 acres to the permit. The Division has the following
adequacy comments. None of the maps submitted with the proposed conversion application clearly show a well
delineated permit boundary, with the appropriate legends. Please provide new maps showing a clearly delineated
permit boundary with legends. Even though the outline of the permit boundary can be identified from the
submitted maps, it would help the reviewer, if the maps clearly show the delineated permit boundary with an
appropriate legend. Please provide new maps as requested.
6.4.4 Exhibit "D" Mining Plan
1. The operator plans to mine the 93.25 acres in three phases. Phase I will cover 46 acres, Phase II will cover
20.25 acres and Phase III will cover 27 acres. The maximum depth of mining is going to be 25-30 feet of
the clay,seam, 5-10 feet of the sandstone cap rock and 5 to 10 feet of the clay seam. Some blasting is
proposed, that will be conducted by a licensed professional. A high wall will be part of the mining
operation and the operator plans to minimize the overall height and the lineal feet of all high wall.
a) Please provide the maximum length and height of the high wall that will be in place at any given time
that will require the slopes to be cut from the mining slopes of 1.5:1 to post mining slopes of 3:1, as
proposed. The only reference to the maximum lineal feet of high wall is mentioned in exhibit "L"
reclamation cost estimate, where 400 lineal feet of high wall reduction cost was used to calculate the
reclamation warranty.
6.4.4 Exhibit "E" Reclamation Plan
The operator is committed to cutting all high wall slopes to at least 3:1 as part of the final reclamation for
the pit. An average of 10 inches of growth medium is proposed to be placed throughout the affected area,
with 40lbs/acre of fertilizer. Seed mix is in accordance with the recommendation of the local soil
conservation district. A noxious weed control plan is in place. The Division recommends all available top
soil should be salvaged and placed throughout the affected area. Where is the location of the top soil
stockpile in any of the maps? Please provide the location of the stockpiles that will be placed within each
phase, in both the mining and reclamation maps.
