Exhibit 1 CMLRB 112 Permit Application
Agile Stone Systems. Inc.
• 2.2 Map Unit B Sandstone Quarry Area
An existing abandoned sandstone quarry and associated undisturbed rocky soils on
convex, moderately steep sideslopes make up this unit. Of the azea proposed to be
disturbed, approximately 66% consists of rock outcrops, surface rock exposures, and soils
less than 6" deep to bedrock. Shallow soils to a depth of 9" to bedrock (sample S-3)
occur over the remaining 33% of the area proposed to be disturbed. This shallow soil
typically has a gravelly sandy clay texture, a pH of 8.1, an electrical conductivity of 0.4
mmhos/cm, and exhibits approximately 35% coarse fragments (gravel) throughout the
profile.
Though suitable to marginally suitable for salvage (in terms of chemical and physical
characteristics) to a depth of approximately 9", salvage of this soil over the portion of the
disturbed area where it occurs will be difficult. Salvageable depths occur in a mosaic
with rock outcrops, surface rock exposures, tree stands, and very shallow soils making
salvage operations potentially problematic, especially in terms of stockpiling. Soil
salvage will also be compromised due to safety issues surrounding soil location near
natural highwalls. Proximity of the Salvage of this soil should be considered
opportunistic with the volume available for stockpile and reapplication uncertain.
2.3 Map Unit C Granite Quarry Area
This unit occurs on steep, concave-convex, foothill sideslopes. Approximately 75% of
the unit consists of rock outcrops, surface rock exposures, incised drainages between
• bedrock outcrops, and soils less than 6" deep to bedrock. Shallow soils ranging from 6
to 12" deep to bedrock (sample S-4) occur over the remaining 25% of the area proposed
to be disturbed. This shallow soil typically has a very gravelly sandy clay texture, a pH
of 8.2, and an electrical conductivity of 8.2 mmhos/cm. Approximately 50% coazse
fragments (gravel) occur throughout the profile with coarse fragment content decreasing
as elevation increases.
This soil is marginally suitable for salvage to an average depth of 9" due to the high
coarse fragment content. Deeper salvage is restricted by the presence of bedrock. As
with the soil of Map Unit B, salvage of this soil will be difficult considering operational
and safety factors. The soil occurs in a mosaic pattern with rock outcrops, surface rock
exposures, tree stands, and very shallow soils. Both collection and transport of soils to
stockpile areas will likely be inefficient. Salvage operations may occur opportunistically
over this unit with the lower slope positions potentially supplying the majority of the
volume of soil available for salvage.
2.4 Map Uuit D Gravel Pit and Plant Areas
Plant Area and parts of Gravel Pit IB: Map Unit D soils (sample S-5) overlie a
nearly level, slightly convex gravel bar bordering Tallahassee Creek. Coazse soils
ranging from 6 to 12"+ deep overly approximately 60% of this unit. The remaining 40%
of the unit consists of coarse soils less than 6" deep to a cobble layer and acobble/rock
deposit at the surface. The dominant soil typically has very gravelly sandy clay loam
• texture, a pH of 7.0, and an electrical conductivity of 0.3 mmhos/cm to a depth of ]2".
