Exhibit D Ch1LRB i 12 Permit Application
Agile Stone Systems. Inc.
• 2.0 MINING
2.1 PREVIOUS MINING
No known mining has occurred within the project permit boundaries or disturbed
operational boundaries other than the very small (< 1/3 acre) sandstone dimensional stone
quarry located. The applicant's proposed sandstone quarry will completely incorporate
the previous sandstone quarry site. A former feldspaz processing facility site
immediately east of the project site is currently a residence. Along abandoned milling
site existed on private land southeast of the project on the south bank of the Arkansas
River. The project in this application has no connection whatsoever with these 2 past or
current neighboring land uses, ownership, or site conditions involving any past mining.
Field investigations by Azurite, Inc. (10/97) confirmed these conclusions.
2.2 Gravel Bar Aggregate Pit
The Gravel Bar Aggregate Pits are located south of Tallahassee Creek and north of the
Arkansas River. Coarse aggregate, decorative stone, sand, road base course, surfacing,
erosion control and other aggregate products will be produced from these pits.
The gravel bar deposit will be mined in three phases. Phase I involves Gravel Area "A",
Gravel Area "B", and the Plant Area as marked on the Mining Plan Map. Most of the
initial effort will focus in Gravel Area B for mining and the Plant Area for crushing,
screening and stockpiling. Phase I acreage disturbance in the mining and plant areas will
total 9.5 acres in Gravel Area A, 7.3 acres in gravel azea B, and 18.1 acres in the plant
• area. The plant area currently slopes up to the north. It will be lowered an average of
about 8' to help hide the plant area. The plant area will be sloped to correspond to the
railroad grade to facilitate safe loading and provide some slope for drainage into the
gravel pits. The reduced plant elevation is also designed to reduce noise levels due to the
topsoil stockpile and other berms located south of the plant azea. The gravel from the
plant area will be placed on Gravel Area IB for plant feedstock once the top soil is
removed from Gravel Area 1B.
Each of the shallow gravel bar pit areas will be mined by a combination of tracked and
rubber tired heavy construction equipment including scrapers, dozers, end-loaders and
haul trucks. Topsoil and fines laden sub-soils, where present, will be loosened if
necessary by ripping or pushing with a bulldozer. If possible, surface materials as well at
the unconsolidated gravels and sands will be mined and loaded via front-end-loader and
truck hauled to the plant area. Where possible, gravel sizing and screening operations,
which do not require crushing, will occur in the pit areas to minimize truck hauling and
screening and placed directly in product stockpiles.
Sized and screened products not sold from the gravel portable sizing, screening and
crushing operations will be used for the construction of the permanent berms designed to
reduce any noises from operations and minimize the amount of the project seen from
Highway 50. The expected locations and dimensions of the berms aze shown under
Exhibit C-Mining Plan Map.
