The equation for calculating the necessary emission reductions per unit for units currently using Reduction Credits.

Where:

     ∆E = the differential of emissions;

     LA = the maximum level of activity;

     ERold = the existing NOX emission rate for the affected unit in pounds per unit of activity;

     ERnew = the new NOX emission rate for the affected unit in pounds per unit of activity; and

     d = (A) to calculate annual emission reductions, d = 365; and

           (B) to calculate emission reductions for the remainder of a control period, d = the number
                 of days remaining in the control period.
