EXHIBIT D
MINING PLAN
Connell Resources, Inc. (herein Connell) currently has sand and gravel mining, an asphalt batch
plant, and headquarters just north of the proposed Wellington Downs permit site (known as the
Stute Pit, M-81-007). They have been operating the Stute Pit since 1990. Connell supplies local,
county, and state governments as well private industry with aggregate and asphalt. Connell has
just about exhausted the sand and gravel reserves and is in the process of reclaiming the site,
therefore,they must relocate to the Wellington Downs deposit.
The proposed permit area for the Wellington Downs operation is 109.5 acres, of which 93.1 acres
will be disturbed by mining.
The Wellington Downs deposit has been drilled and contains an estimated 1.2 million cubic
yards of sand and gravel. The deposit has 4.5 average depth of overburden and a 10 foot average
depth of sand and gravel. The overburden will be removed and stockpiled for reclamation.
About 10%of the deposit will be unmarketable fines and used along with the topsoil and
overburden for reclamation.
P asin
Currently Connell processes 200,000 and 250,000 tons of aggregate per year. They expect to
keep this same rate of production at the Wellington Downs site. They will mine between 10 to
15 acres a year. At this rate of mining they expect to mine and reclaim the site in 8 to 10 years.
The operation will be mined in phases to limit the area of disturbance at any one time (see
Exhibit Q. The phases depicted in Exhibit C are used to indicate the direction of mining. These —
phases are neither representative of the maximum area of disturbance nor do they limit
disturbance to a particular phase. In Phase 1 Connell will mine the southeast end of the deposit.
Mining will proceed from west to east. A portion of Phase I will be backfilled and topsoiled and
Connell will locate their stationary equipment here.
Phase 2 of the operation will consist of mining a 100 foot wide strip around the perimeter of the
property. This will allow Connell to install an aquitard boundary around the entire property and
obtain marketable aggregate in the process. The aquitard boundary will minimize the
groundwater inflow into the pit and limit the potential effects of dry mining on surrounding well
owners. The construction of the liner will be concurrent with mining of Phase 2.
Topsoil and overburden will be temporarily stockpiled along the boundary of Phase 2. As the
perimeter is sealed, stockpiled overburden and topsoil will be used to backfill portions of Phase 2
that are not included in the final reclamation plan.
