NR 422.125(3) (3) Compliance methods.

NR 422.125(3)(a) (a) Emission averaging. In addition to using provisions of s. NR 422.04 or 425.05 to demonstrate compliance, an owner or operator may demonstrate compliance with the emission limitations in sub. (2) (a) and (b) by showing that total daily actual emissions calculated using Equation 2 are less than or equal to total daily allowable emissions calculated using Equation 1.
