Biochemical Oxygen Demand (BOD). The quantity of oxygen utilized in the biochemical oxidation of organic matter amenable to measurement by the methods described in Standard Methods for the examination of Water and Wastewater, 18th edition, 1992; under standard laboratory procedures for five (5) days at 20° centigrade, usually expressed as a concentration [milligrams per liter (mg/L)]. I. Categorical Pretreatment Standard or Categorical Standard. Any regulation containing pollutant discharge limits promulgated by the US EPA in accordance with Sections 307(b) and (c) of the Act (33 USC 1317) which apply to a specific category of users and which appear in 40 CFR Chapter I, Subchapter N, Parts 405-471.
