(c) "Authority" means the Service Director and the Superintendent of the Dover WWTP, or other designated official of the City, or their duly authorized representative. It can also be used to describe the wastewater treatment plant.
(d) "Biochemical oxygen demand" or "BOD" means the quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure in five (5) days at 20 degrees C expressed in terms of weight and concentration. The oxygen demand measured is the sum of carbonaceous and nitrogenous demands. 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.
(e) "Bypass" means the intentional diversion of wastestreams from any portion of the pretreatment treatment facility.
(f) "Categorical pretreatment standard" is the same as "national categorical pretreatment standard."
(g) "Discharger" is the same as "industrial user."
(h) "Indirect discharge" or "discharge" means the introduction of pollutants into the water pollution control facility from a non-domestic source regulated under 307(b), (c) or (d) of the Act.
(i) "Industrial discharge permit” means a formal permit to discharge industrial waste into the WWTP, as issued by the City.
(j) "Industrial user" or "user” means a source of indirect discharge.
(k) "Industrial waste” means any substance resulting from any process of industrial, commercial, governmental and institutional concerns, manufacturing, business, trade, or research, including the development, recovery, or processing of natural resources, or from sources other than those generating waste defined as normal domestic sewage herein.
(l) "Industrial discharge permit" means a formal permit to discharge industrial waste into the WWTP, as issued by the City.
(m) "Interference” means a discharge which, alone or in conjunction with a discharge or discharges from other sources, both:
(1) Inhibits or disrupts the WWTP, its treatment processes or operations, or its sludge processes, use or disposal; and,
(2) Therefore is a cause of a violation of any requirement of the WWTP's NPDES permit (including an increase in the magnitude or duration of a violation) or of the prevention of sewage sludge use or disposal.
(n) "Law Director" means the Director of Law of the City, or his authorized deputy, agent, or representative.
(o) "May" is permissible.
(p) "National categorical pretreatment standard" or "categorical pretreatment standard” means any regulation containing pollutant discharge limits promulgated by the EPA in accordance with Section 307(b) and (c) of the Act (33 U.S.C. 1347) which applies to a specific category of industrial users.
(q) “National Pollutant Discharge Elimination System (NPDES) permit" means a permit issued by the State of Ohio EPA or United States EPA pursuant to the Act for the purpose of regulating the discharge of sewage, industrial wastes, and other wastes under the authority of Section 402 of the Act, into the navigable waters of the United States.
(r) "New source" means any building, structure, facility or installation from which there is or may be a discharge of pollutants, the construction of which commenced after the publication of proposed pretreatment standards under Section 307(C) of the Act which will be applicable to such source if such standards are thereafter promulgated in accordance with that section, provided that:
(1) The building, structure, facility or installation is constructed at a site at which no other source is located;
(2) The building, structure, facility or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or,
(3) The production or wastewater generating processes of the building, structure, facility or installation are substantially independent of an existing source at the same site.
(s) "Pass through" means a discharge which exits the WWTP 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 WWTP's NPDES permit (including an increase in the magnitude or duration of a violation).
(t) “Person” means 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. The masculine gender shall include the feminine. The singular shall include the plural where indicated by the context.
(u) "pH" means the logarithm, base ten, of the reciprocal of the hydrogen concentration expressed in moles per liter.
(v) "Pretreatment” means the process of reducing the amount of pollutants, eliminating pollutants, or altering the nature of pollutant properties in wastewater prior to introducing such pollutants into the City's wastewater disposal system. The reduction, elimination, or alteration may be obtained by physical, chemical, or biological processes, process changes or other means, except as prohibited by this subchapter.
(w) "Sanitary sewer" means any pipe, conduit, ditch, or other device used to collect and transport sewage from the generating source including combined sewers.
(x) "Service Director" means the Director of Public Service of the City, or his authorized deputy, agent, or representative.
(y) "Sewer" means any pipe, conduit, ditch or other device used to collect and/or transport sewage.
(z) "Shall" is mandatory.
(aa) "Significant industrial user" or "SIU" includes the following:
(1) All industrial users subject to categorical pretreatment standards; and
(2) Any other industrial user that: discharges an average of 25,000 gallons per day or more of process wastewater to the WWTP; contributes a process wastestream which makes up 5 percent or more of the average dry weather hydraulic or organic capacity of the WWTP; or has a reasonable potential, in the opinion of the Service Director, to adversely affect the WWTP's operation or for violating any pretreatment standard or requirement.
(bb) "Sludge" means any solid, semi-solid, or liquid waste generated by a municipal, commercial, or industrial wastewater treatment plant, water supply treatment plant, or air pollution control facility or any other waste having similar characteristics and effects.
(cc) "Slugload" means any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a discharge at a flow rate and/or pollutant concentration which will cause interference with or pass through the WWTP.
(dd) "Suspended solids" means solids that either float on the surface of, or are in suspension or will settle in water, sewage, or industrial waste, and which are removable by a laboratory filtration device. Quantitative determination of suspended solids shall be made in accordance with procedures set forth in Standard Methods.
(ee) "Upset" means an exceptional incident in which a discharger unintentionally and temporarily is in a state of noncompliance with pretreatment standards due to factors beyond the reasonable control of the discharger, and excluding noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation thereof.
(ff) “User” means the same as "industrial user".
(gg) “Wastewater treatment plant (WWTP)" means an assemblage of devices, structures, and equipment for treatment of sewage and industrial waste.
