49.3.1.3.1 Soils classification of each field as mapped or descriped by the U.S. Department of
Agriculture, Soil Conservation Service.
The subject property consists of two predominant soil classifications with varying
slopes:
i. Oleny loamy sand - 44
ii. Valent sand - 69, 70 and 72
Enclosed is an aerial photo showing the types and a specific descriptions of each of
the two classifications and types.
49.3.1.3.2 Soil test data including the following parameters:
Site Site 49.2.1.12.10
Parameter Units Composite Composite Standard
(ppm) (lbs/ac) (lbs/ac)
Soil, Texture
pH pH Units 8.05
CEC meg/100g 7.45
Nitrate as N ppm 7.75 27.90
Phosphorus ppm 23.75 85.50
Potassium ppm 185.00 666.00
Sodium ppm 124.50 448.20
Cadmium ppm 0.17 0.60 5
Copper ppm 0.45 1.62 125
Lead ppm 0.10 0.34 350
Nickel ppm 0.04 0.15 50
Znic ppm 0.80 2.88 250
Four soil samples, enclosed, were collected from composited samples from the
entire 70 acre site. Two samples were composited from samples taken above the
Coal Ridge Ditch and two samples were composited from samples take below the
ditch. Of the two composite samples collected above and below the ditch, one
consisted of the 8 samples collected in the upper 1 foot of soil (sample#1 and#3
enclosed). The other sample consisted of 8 samples collected from 2 - 4 feet of
soil (sample #2 and#4 enclosed).

49.3.3.3.3 Soil test data demonstrating that five feet of suitable soil will exist at all sludge
application sites between the plowline and the top of the high ground water table.
The"plowline" on the subject site is no more the one foot resulting from tillage
practices using a disk or chisel. The depth to water measurements were 8.4 feet
below the exiting ground surface(see Hydrologic Data section). Thus,
approximately a minimum of 7 feet exists between plowline and high ground water
table. The soil on site does not exceed 49.2.1.12.10, shown in the table above.
Based on soil samples and the trace elements in the soil do not exceed those set
forth in 49.2.1.12.10. According to the ASCS the Olney loamy sand is suitable for
winter wheat with a routine fallowing program with adequate maintenance of soil
fertility. The Valent sand is suited for the production of wheat with adequate
fallow and soil fertility according to the ASCS. See enclosed SCS soil survey
reports.
