Notes:

a Chemical Abstract Service (CAS)

b USEPA Test Methods (SW-846)

* 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 106mg/kg)

Where:

ARE = application rate equivalent (mg/kg) for coarse-textured, low organic matter content soils

Applicationrate = current label application rate (1b/acre)
