NR 254.004
NR 254.004 Calculation of pretreatment standards. NR 254.004(1)(1) Pretreatment standards shall be calculated for each operation using the applicable average rate of production reported by the owner or operator of the facility to the control authority in accordance with
s. NR 211.15.
NR 254.004(2)
(2) The average rate of production reported by the owner or operator in accordance with
s. NR 211.15 may not be based upon the design production capacity, but rather upon a reasonable measure of actual production of the facility, such as the production during the high month of the previous year or the monthly average for the highest month of the previous 5 years. For new sources or new dischargers, actual production shall be estimated using projected production.
NR 254.004(3)
(3) If the average rate of production for an operation reported in accordance with
s. NR 211.15 does not represent a reasonable measure of actual production due to a change of circumstances, the owner or operator shall submit a modified average rate of production to the control authority.
