NEW SOURCE1. 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:
a. The building, structure, facility, or installation is constructed at a site at which no other source is located; or
The building, structure, facility, or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or
The production or wastewater generating processes of the building, structure, facility, or installation are substantially independent of an existing source at the same site. In determining whether these are substantially independent, factors such as the extent to which the new facility is integrated with the existing plant, and the extent to which the new facility is engaged in the same general type of activity as the existing source should be considered.
(1) Construction on a site at which an existing source is located results in a modification rather than a new source if the construction does not create a new building, structure, facility, or installation meeting the criteria of Section (1)(b) or (c) above but otherwise alters, replaces, or adds to existing process or production equipment.
Construction of a new source as defined under this Subsection has commenced if the owner or operator has:
(a) Begun, or caused to begin, as part of a continuous on-site construction program:
(i) Any placement, assembly, or installation of facilities or equipment; or
Significant site preparation work including clearing, excavation, or removal of existing buildings, structures, or facilities which is necessary for the placement, assembly, or installation of new source facilities or equipment; or
Entered into a binding contractual obligation for the purchase of facilities or equipment which are intended to be used in its operation within a reasonable time. Options to purchase or contracts which can be terminated or modified without substantial loss, and contracts for feasibility, engineering, and design studies do not constitute a contractual obligation under this Subsection.
NON-CONTACT COOLING WATERWater used for cooling that does not come into direct contact with any raw material, intermediate product, waste product, or finished product.
PASS THROUGHA 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 City's NPDES permit, including an increase in the magnitude or duration of a violation.
PERSONAny individual, partnership, co-partnership, firm, company, corporation, association, joint stock company, trust, estate, governmental entity or any other legal entity, or their legal representatives, agents or assigns. The masculine gender shall include the feminine, the singular shall include the plural where indicated by the context.
pHThe logarithm (base 10) of the reciprocal of the concentration of hydrogen ions expressed in grams per liter of solution.
POLLUTANTAny dredged spoil, solid waste, incinerator residue, sewage, garbage, sewage sludge, munitions, medical wastes, chemical wastes, biological materials, radioactive materials, heat, wrecked or discharged equipment, rock, sand, cellar dirt, industrial, municipal, and agricultural waste discharged into water, and certain characteristics of wastewater (e.g., pH, temperature, TSS, turbidity, color, BOD, COD, toxicity, or odor).
POLLUTIONThe man-made or man-induced alteration of the chemical, physical, biological, and radiological integrity of water.
PRETREATMENT or TREATMENTThe reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater prior to or in lieu of discharging or otherwise introducing the pollutants into a POTW. The reduction or alternation may be obtained by physical, chemical or biological processes, process changes or by other means, except as prohibited by 40 CFR
403.6(d). Appropriate pretreatment technology includes control equipment, such as equalization tanks or facilities, for protection against surges or slug loadings that might interfere with or otherwise be incompatible with the POTW. However, where wastewater from a regulated process is mixed in an equalization facility with unregulated wastewater or with wastewater from another regulated process, the discharge from the equalization facility must meet an adjusted pretreatment limit calculated in accordance with 40 CFR
403.6(e).
Any substantive or procedural requirement related to pretreatment, other than a national pretreatment standard imposed on an industrial user.
PUBLICLY OWNED TREATMENT WORKS (POTW)A treatment works as defined by Section 212 of the Act (33 U.S.C. §
1292) which is owned in this instance by the City. This definition includes any sewers, devices or systems used in the collection, storage, treatment, recycling, and reclamation of sewage or industrial wastes of a liquid nature and any conveyances which convey wastewater to a treatment plant. For the purposes of this Chapter, "POTW" shall also include any sewers that convey wastewaters to the POTW from persons outside the City of St. Peters who are, by contract or agreement with the City of St. Peters, users of the City of St. Peters' POTW.
Any sewage from holding tanks such as vessels, chemical toilets, campers, trailers, and septic tanks.
SEWAGEHuman excrement and gray water (household showers, dishwashing operations, etc.).
SHALLIs mandatory; MAY: Is permissive.
SIGNIFICANT INDUSTRIAL USER1. The term significant industrial user means:
a. All industrial users subject to Categorical Pretreatment Standards under 40 CFR
403.6 and
40 CFR Chapter
I, Subchapter N; and
Any other industrial user that: discharges an average of twenty-five thousand (25,000) gallons per day or more of process wastewater to the POTW (excluding sanitary, non-contact cooling and boiler blowdown wastewater); contributes a process waste stream which makes up five percent (5%) or more of the average dry weather hydraulic or organic capacity of the POTW treatment plant; or is designated as such by the Manager on the basis that the industrial user has a reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement (in accordance with 40 CFR
403.8(f)(6)).
The control authority may determine that an industrial user subject to categorical pretreatment standards under Section 403.6 and
40 CFR Chapter
I, Subchapter N is a non-significant categorical industrial user rather than a significant industrial user on a finding that the industrial user never discharges more than one hundred (100) gallons per day (gpd) of total categorical wastewater (excluding sanitary, non-contact cooling and boiler blowdown wastewater, unless specifically included in the pretreatment standard) and the following conditions are met:
a. The industrial user, prior to the control authority's finding, has consistently complied with all applicable categorical pretreatment standards and requirements;
The industrial user annually submits the certification statement required in Section 403.12(q) together with any additional information necessary to support the certification statement; and
The industrial user never discharges any untreated concentrated wastewater discharge.
Upon a finding that an industrial user meeting the criteria in Paragraph (1)(b) of this definition has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, the Manager may at any time, on its own initiative or in response to a petition received from an industrial user, and in accordance with 40 CFR
403.8(f)(6), determine that such industrial user is not a significant industrial user.
SLUG LOAD or SLUG DISCHARGEAny discharge at a flow rate or concentration which could cause a violation of the prohibited discharge standards. A slug discharge is any discharge of a non-routine, episodic nature, including, but not limited to, an accidental spill or a non-customary batch discharge, which has a reasonable potential to cause interference or pass through, or in any other way violate the POTW's regulations, local limits or permit conditions.
STANDARD INDUSTRIAL CLASSIFICATION (SIC)A classification pursuant to the Standard Industrial Classification Manual issued by the Executive Office of the President, Office of Management and Budget, 1972.
STORM WATERAny flow occurring during or following any form of natural precipitation and resulting therefrom, including snowmelt.
