    BOD means the quantity of oxygen, expressed in milligrams per liter, utilized in the biochemical oxidation of organic matter under standard laboratory conditions of five days at a temperature of 20 degrees Celsius. The laboratory determinations shall be made in accordance with 40 CFR 136.

    Building drain means that part of the lowest horizontal piping of a drainage system which receives the discharge from soil, waste and other drainage pipes of the building and conveys it to the building sewer, beginning three feet outside the inner face of the building wall.

    Building sewer means the extension from the building drain to the sanitary sewer or other place of disposal.

    Categorical industrial user means an industrial user subject to a categorical pretreatment standard or categorical standard.

    COD means the measure of the oxygen-consuming capacity of inorganic and organic matter present in water or wastewater, expressed in milligrams per liter as the amount of oxygen consumed from a chemical oxidant in a specific test. The laboratory determinations shall be made in accordance with 40 CFR 136.

    Composite sampling means a sample made up of grab samples collected at equal intervals and then combined proportional to flow, a sample continuously collected proportionately to flow or equal volumes taken at varying time intervals.

    Significant industrial users means:


    All dischargers subject to categorical pretreatment standards under 40 CFR 403.6 and 40 CFR chapter I, subchapter N; and


    All noncategorical dischargers that, in the opinion of the control authority, have a reasonable potential to adversely affect the POTW's operation or that contribute a process wastestream which makes up five percent or more of the average dry-weather capacity of the POTW treatment plant or that discharge an average of 25,000 gallons per day or more of process wastewater to the POTW. However, the control authority need not designate as significant any noncategorical industrial user that, in the opinion of the control authority and with the agreement of the approval authority, has no potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement. The agreement of the approval authority is not necessary if the noncategorical discharger would have been designated as significant only because of an average discharge of 25,000 gallons per day or more of process wastewater. Any noncategorical industrial user designated as significant may petition the control authority to be deleted from the list of significant industrial users on the grounds that it has no potential for adversely affecting the POTW's operation or violating any pretreatment standard or requirement.

    Significant noncompliance means, for a significant industrial user meeting one or more of the following criteria, or any industrial user which meets the criteria in (3), (4), or (8):


    Chronic violations of wastewater discharge limits, defined here as those in which 66 percent or more of all of the measurements taken for the same pollutant parameter during a six-month period exceed (by any magnitude) a numeric pretreatment standard or requirement, including instantaneous limits, as defined by 40 CFR 403.3(l);


    Technical review criteria (TRC) violations, defined here as those in which 33 percent or more of all of the measurements taken for the same pollutant parameter during a six-month period equal or exceed the product of the numeric pretreatment standard or requirement including instantaneous limits, as defined by 40 CFR 403.3(l) multiplied by the applicable TRC (TRC=1.4 for BOD, TSS, fats, oil, and grease, and 1.2 for all other pollutants except pH);


    Any other violation of a pretreatment standard or requirement as defined by 40 CFR 403.3(l) (daily maximum, long-term average, instantaneous limit, or narrative standard) that the city determines has caused, alone or in combination with other discharges, interference or pass through (including endangering the health of city personnel or the general public);


    Any discharge of a pollutant that has caused imminent endangerment to human health, welfare or to the environment or has resulted in the city's exercise of its emergency authority to halt or prevent such a discharge;


    Failure to meet, within 90 days after the scheduled date, a compliance schedule milestone contained in an individual wastewater discharge permit or enforcement order for starting construction, completing construction, or attaining final compliance;
