|
* Application Rate Equivalents (AREs) are based on
USEPA-approved pesticide label rates for the specific pesticide active
ingredient and conservative assumptions about soil properties. AREs only
apply to the upper three inches of soil and are used as the Soil Cleanup
Objective (SCO) if the ARE is greater than the SCO value calculated using the
Equation in 8 Ill. Adm. Code 259.350(a).
|
|
|
|
|
The application rate equivalents
can be determined using the equation below:
ARE (mg/kg)
|
=
|
Application Rate (1b/acre) x
(1 acre-foot / 43,560 ft3) x (1 ft3 / 110 1b) x (1 /
0.25 ft) x (1.0 x 106 mg/kg)
|
Where:
ARE = application rate equivalent (mg/kg) for coarse-textured, low
organic matter content soils
Applicationrate = current label application rate (1b/acre)
