(2) Technical review criteria (TRC) violations, defined here as those in which 33% or more of all of the measurements for each pollutant parameter taken during a six-month period equal or exceed the product of the daily maximum limit, the average limit or the instantaneous limit multiplied by the applicable TRC (TRC = 1.4 for BOD, TSS, fats and oils and greases, and 1.2 for all other pollutants, except pH) for any significant industrial user;
(3) Any other violation of a pretreatment effluent limit (the instantaneous limit, daily maximum or longer term average) that the Superintendent determines has caused, alone or in combination with other discharges, interference or pass through (including endangering the health of POTW personnel or the general public);
