Re M- 1997 -064 conversion adequacy review
Dear Miss`Belantoni:
The 'Division has reviewed .your 112 conversion application for permit # M- 1997 -064. The conversion
application proposes to convert the 110 gypsum mine from the currenV9.73 acres to a phased 112 with
559:22 acres. The following is the Division's adequacy concerns.
{). Exhibit A Legal Description 6.4.1
a) Under legal description the operator states, " The legal description of the land to be
permitted is as follows, 592.42 acres in the fractional part of East% of the East %Z West %.
of the East Y2 and the West % of section 26 ". However, on the General Informational :page
1 item # 3, 3.2 the. total permitted acres.is listed as 559.22; please clarify.
l.) Exhibit -D Mining Plan 6;4.4
a) The operator plans to utilize the old 110 affected area. as temporary top soil storage area
and to also temporarily reclaim the old 110 area. As noted during the pre- operational
inspection, the Division encourages any activity related to reclamation. However if to soil
is going to be stored for more than 180 days, GCC as noted in their reclamation plan must
stabilize the stockpile.
b) On Page 7, the last paragraph the operator states, "Depending on the integrity of the
materail3 :1 slopes will be maintained throughout mining. by pushing: deposit with a dozer
onto the aline floor. In the event slope material is too fragile to support equipment, fifty.
foot benches will be constructed for every 15 foot of vertical drop. Since GCC'S plan is to
maintain a 3:1 slope during mining and post mining, are `these benches going to be "
temporary? The maximum depth of mining is going to be 30 feet( maximum depth of
deposit) according to the current mining plan, if the need arises, the operator will need to
DO
submit a technical revision to change the plan from a 3:1 to the bench mining.
