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 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 of production equipment that causes the discharge of pollutants at an existing source; or
The production or wastewater-generating processes or the building, structure, facility or installation are substantially independent of an existing source at the same site. In determining if 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 shall 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

Entered into a binding contractual obligation for the purchase of facilities or equipment which is 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.
NORMAL OPERATING DAYA twenty-four-hour day or such fewer hours during which standard and routine operations and work of the facility are conducted. It would include but is not limited to daily cleaning, routine maintenance and production. It would not include work stoppages, scheduled and unscheduled shutdowns, holiday schedules, major cleanup and the like.

PRETREATMENT or TREATMENTThe reduction of the amount of pollutant, the elimination of pollutants, the alteration of the nature 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 in the POTW. The reduction or alteration can be obtained by physical, chemical or biological processes or process changes by other means, except as prohibited by 40 CFR
403.6(d).

A user that:
(a) Discharges an average of 25,000 gallons per day (gpd) or more of process wastewater to the POTW per normal operating day; or
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 Commission 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 (b) has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, the Commission may at any time, on its own initiative or in response to a petition received from a 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.
SLUGOperating day of water, wastewater or industrial waste which, in concentration of any given constituent or in quantity of flow, exceeds for any period of duration longer than 15 minutes more than five times the average twenty-four-hour concentration or flow during a normal operating day.
