COD (CHEMICAL OXYGEN DEMAND). The quantity of oxygen consumed from a chemical oxidation of inorganic and organic matter present in the water or wastewater, expressed in mg/l, as described in the Fourteenth Edition of Standard Methods for the Examination of Water and Wastewater, published by the American Public Health Association.

PERMIT. A written authorization granted by the General Manager to an industrial customer for that customer to discharge sewage into the sewer system and describing in detail the terms and limits of service.
pH VALUE. The logarithm of the reciprocal of the hydrogen ion concentration in grams per liter; i.e., ph= 1
pH will be determined according to the Fourteenth Edition of Standard Methods for the Examination of Water and Wastewater, published by the American Public Health Association.
PRODUCER. Any person, firm, association, corporation, or trust which owns, operates, possesses, or controls an establishment or plant that is classified as an industrial waste user.
