Laboratory procedures shall be in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater, as defined in this section.
BYPASS. The intentional diversion of waste-streams from any portion of the pretreatment treatment facility.
CFR. Code of Federal Regulations.
CATEGORICAL PRETREATMENT STANDARD. Same as NATIONAL CATEGORICAL PRETREATMENT STANDARD.

INSTANTANEOUS MAXIMUM ALLOWABLE DISCHARGE LIMIT. The maximum concentration of a pollutant allowed to be discharged at any time, determined from the analysis of any discrete or composited sample collected, independent of the industrial flow rate and the duration of the sampling event.
INTERFERENCE. A discharge which, alone or in conjunction with a discharge or, discharges from other sources, inhibits or disrupts the POTW, its treatment processes or operations, or its sludge processes, use or disposal; and, therefore is a cause of a violation of any requirement of the POTW's NPDES Permit (including an increase in the magnitude or duration of a violation) or of the prevention of sewage sludge use or disposal.

NONCONTACT COOLING WATER. Water used for cooling which does not come into direct contact with any raw material, intermediate product, waste product, or finished product.
PASS THROUGH. A discharge which exits the POTW into waters of the United States in quantities or concentrations which, alone or in conjunction with a discharge or discharges from other sources, is a cause of a violation of any requirement of the POTW's NPDES permit (including an increase in the magnitude or duration of a violation).
PERSON. Any and all persons, natural or artificial, including any individual, firm, company, private corporation, partnership, co-partnership, joint stock company, trust, association, institution, enterprise, or other legal entity, or their representatives, agents, or assigns.
