RE : Technical Revision - Expansion of Sutey Coal Refuse Pile
Configuration - Coal Basin Permit File No . C-017-81
Dear Candace :
Transmitted herewith is a technical revision request to
the Coal Basin Permit Application that is designed to expand the
size and storage capacity of the Sutey Coal Refuse Pile .
This revision is required at this time to accommodate a
larger working area and greater volume capacity for coal refuse
than was anticipated at the time the permit revision for the
facility was submitted and approved . The greater working area
is needed for new layers of refuse to dry out sufficiently
for proper compaction before another layer is deposited . The
increased volume of coal refuse is resulting from unanticipated
increases in the volume of production and in the percentage of
the processed coal that is being discarded to meet the high quality
requirements of 'ou customers . It was estimated that the percent-
age of waste of thliPprocessed coal would not exceed 25% . However ,
on occasions , it has exceeded 40% . These two factors have
increased our estimated storage volume for the Phase I pile from
approximately 175 , 000 cu yards per year to approximately 434 , 000
cu yards per year .
Our proposal is to increase the storage area to the north
just short of the stream diversion channel as indicated on the
attached construction drawings . This Phase II design will provide
storage for approximately 1 , 700, 000 cu yards of refuse , or a
total of four year ' s disposal at the current rate (430 , 000 cu
yards per year) . The Phase II configuration will extend the life
of the pile well into the next permit period which commences on
June 1 , 1988 . The increased area will provide adequate space
to properly spread , drain and compact the refuse during the wet
winter months . By April of 1989 , if rates of production and
disposal percentages remain as they are now, a Phase III design
will be submitted that will require an extension of the conveyor
system and a Special Use permit for some Forest Service land
north of the present Sutey boundary .
