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[2] that will be applicable to such source if such standards are thereafter promulgated in accordance with that section, provided that:
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.
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 Subsection A(2) or (3) above but otherwise alters, replaces, or adds to existing process or production equipment.
Construction of a new source as defined under this definition has commenced if the owner or operator has:
Begun, or caused to begin, as part of a continuous on-site construction program:

Water used for cooling that does not come into direct contact with any raw material, intermediate product, waste product, or finished product.
An industry which does not meet the definition of a significant industrial user, but is permitted by the City because it has a possibility of discharging incompatible pollutants in excess of local discharge limits or is required to have a spill control plan.
Any waste delivered by truck that does not satisfy the definition of septage or holding tank wastes. Other wastes may include commercial wastes that include materials other than sanitary wastes.
The discharge of pollutants through the facility into waters of the state in quantities or concentrations which, alone or in conjunction with a discharge or discharges from other sources, is a cause of violation of any requirement of the District's NPDES permit (including an increase in the magnitude or duration of a violation).
Any individual, firm, company, association, corporation, trust or government authority, partnership, public or private corporation or authority, association, trust, estate, governmental entity, agency or political subdivision of a municipality, the State of Maine, or the United States, or any other legal entity, or its legal representative, agent, or assign.

These may be but are not limited to: dredged spoil, solid waste, incinerator residue, filter backwash, sewage, garbage, sewage sludge, munitions, medical wastes, chemical wastes, biological materials, radioactive materials, heat, wrecked or discarded equipment, rock, sand, cellar dirt, municipal, agricultural and industrial wastes, and certain characteristics of wastewater (e.g., pH, temperature, TSS, turbidity, color, BOD, COD, toxicity, or odor).

This definition includes any devices and systems used in the storage, treatment, recycling, disposal, and reclamation of wastewater and sewage consisting of domestic, commercial, municipal, and industrial wastes of a liquid nature. It also includes those sewers, pipes, and other conveyances which convey wastewater to the facility. For the purposes of these rules and regulations, POTW shall also include any sewers that convey wastewaters to the treatment works from persons who are, by permit, contract, or agreement with the City, users of the facility.
That portion of the facility designed to provide treatment (including recycling and reclamation) of wastewater, municipal sewage, industrial waste, septage and holding water.
The reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater to a less harmful state prior to or in lieu of discharging or otherwise introducing such pollutants into the facility. The reduction or alteration can be obtained by physical, chemical or biological processes, process changes, or other means, except as prohibited by 40 CFR 403.6(d).
Any substantive or procedural requirement related to pretreatment, other than a National Categorical Pretreatment Standard, imposed on a user by the District through its permit process as defined in § 260-67 of these rules and regulations.

Except as provided in Subsection B of this definition, a "significant industrial user" is:
An industrial user subject to categorical pretreatment standards; or
An industrial user that:
Discharges an average of 25,000 gpd or more of process wastewater to the POTW (excluding sanitary, noncontact cooling and boiler blowdown wastewater);
Contributes a process waste stream which makes up 5% or more of the average dry-weather hydraulic or organic capacity of the POTW treatment plant; or
Is designated as such by the City on the basis that it has a reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement.
Upon a finding that a user meeting the criteria in Subsection A(2) of this definition has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, the City may at any time, on its own initiative or in response to a petition received from an industrial user, and in accordance with procedures in 40 CFR 403.8(f)(6), determine that such user should not be considered a significant industrial user.

Any discharge at a flow rate or concentration which could cause a violation of the prohibited discharge standards of these rules. A "slug discharge" is any discharge of a nonroutine, episodic nature, including but not limited to an accidental spill or a noncustomary 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.
