NEW SOURCE(1) 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 that 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.
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 definition has commenced if the owner or operator has:
(a) Begun, or caused to begin, as part of a continuous onsite construction program:
[1] 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 definition.
NONCONTACT COOLING WATERWater used for cooling that does not come into direct contact with any raw material, intermediate product, waste product, or finished product.
OCCUPIED BUILDINGAny structure for continuous or periodic human occupancy from which wastewater is or may be discharged and includes, without limitation, residential dwellings of all kinds, stores, shops, offices, warehouses, factories and business, commercial or industrial establishments.
OWNERAny person vested with ownership, legal or equitable, sole, partial or joint, of any property located in Montgomery Township.
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 POTW-TP's NPDES permit, including an increase in the magnitude or duration of a violation.
PERSONAny individual, partnership, copartnership, firm, company, corporation, association, joint stock company, trust, estate, governmental entity, or any other legal entity; or their legal representatives, agents, or assigns.

As used herein, the term POTW-TP shall, as the circumstances require, refer to the facility treating the wastewater and/or the entity responsible for its operation.
PRETREATMENTThe 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, introducing such pollutants into the POTW. This reduction or alteration can be obtained by physical, chemical, or biological processes; by process changes; or by other means, except by diluting the concentration of the pollutants unless allowed by an applicable pretreatment standard.
PRETREATMENT REQUIREMENTSAny substantive or procedural requirement related to pretreatment imposed on a user, other than a pretreatment standard.
PROPERTY ACCESSIBLE TO A PUBLIC SEWERProperty which adjoins, abuts on or is adjacent to a public sewer or a street or highway in which a public sewer is located, but shall not include any property on which the principal occupied building is located more than 150 feet from a public sewer.
PUBLICLY OWNED TREATMENT WORKS (POTW)A treatment works as defined by Section 212 of the Act (33 U.S.C. 1292), including the POTW treatment plant and any sewers that convey wastewater to the POTW treatment plant, but not including pipes, sewers, or other conveyances not connected to a facility providing treatment. For the purposes of this Part
1, POTW shall also include any sewers that convey wastewaters to the POTW from persons inside or outside Montgomery Township and participating municipalities.
Facilities, including any part of but not necessarily the entirety of a system of such facilities, operated by the MTMSA for the collection of wastewater within Montgomery Township.

RETAINING TANK WASTEAny waste from retaining tanks, such as vessels, chemical toilets, campers, trailers, and septic tanks.
SEPTIC TANK WASTEAny sewage from holding tanks such as vessels, chemical toilets, campers, trailers, and septic tanks.

SIGNIFICANT INDUSTRIAL USER (SIU)Except as provided in Subsection
A(3) and
(4) of this definition, a significant industrial user is:
(1) An industrial user subject to categorical pretreatment standards; or
An industrial user that:
(a) Discharges an average of twenty-five thousand 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 POTW on the basis that it has a reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement.
The POTW-TP may determine that an industrial user subject to categorical pretreatment standards is a nonsignificant categorical industrial user rather than a significant industrial user on a finding that the industrial user never discharges more than 100 gallons per day (gpd) of total categorical wastewater (excluding sanitary, noncontact cooling and boiler blowdown wastewater, unless specifically included in the pretreatment standard) and the following conditions are met:
(a) The industrial user, prior to POTW-TP's finding, has consistently complied with all applicable categorical pretreatment standards and requirements;
The industrial user annually submits the certification statement required in §
187-43B of this Part
1 [see 40 CFR 403.12(q)], together with any additional information necessary to support the certification statement; and
The industrial user never discharges any untreated concentrated wastewater.
Upon a finding that a user meeting the criteria in Subsection
(2) of this part has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, the POTW-TP 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.
SLUG LOAD or SLUG DISCHARGEAny discharge at a flow rate or concentration which could cause a violation of the prohibited discharge standards in §
187-5 of this Part
1.
