Any regulation developed under the authority of Section 307(b) of the Act and 40 CFR 403.5.

NEW SOURCE

Any building, structure, facility or installation from which there is or may be a discharge of pollutants, the construction of which is 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:

The building, structure, facility or installation is constructed at a site at which no other source is located;

The building, structure, facility or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or

(c)

The production or wastewater-generating processes of the building, structure, facility or installation are substantially independent of an existing source at the same site.

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.

POLLUTION

The man-made or man-induced alteration of the chemical, physical, biological or radiological integrity of water.

POTW TREATMENT PLANT

That portion of the POTW designed to provide treatment to wastewater.

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 a POTW. The reduction or alteration can be obtained by physical, chemical or biological processes or process changes by other means, except by diluting the concentration of the pollutants, unless allowed by applicable pretreatment standards.

This definition includes any sewers that convey wastewater to the POTW treatment plant but does not include pipes, sewer or other conveyances not connected to a facility providing treatment. For the purposes of this Part 5, "POTW" shall also include any sewers that convey wastewaters to the POTW from persons outside the Township who are, by contract or agreement with the Township, users of the POTW.

SIGNIFICANT INDUSTRIAL USER

A user:

Subject to categorical pretreatment standards; or

That:

[1]

Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary, non-contact-cooling and boiler blowdown wastewater);

[2]

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

[3]

Is designated as such by the Authority or Township 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 Authority 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, non-contact-cooling and boiler blowdown wastewater, unless specifically included in the pretreatment standard) and the following conditions are met:

The industrial user, prior to the Authority's finding, has consistently complied with all applicable categorical pretreatment standards and requirements;
