Instantaneous maximum allowable discharee limit means the maximum concentration of a pollutant allowed to be dischare:ed at any time. determined from the analysis of any discrete or composite sample collected. independent of the industrial flow rate and the duration of the samplline: event. Interference means a discharge which, alone or in conjunction with a discharge or discharges from other sources, both: 1. Inhibits or disrupts the POTW, its treatment processes or operations, or its sludge processes, use, or disposal; and 2.
