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 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.
(2) 
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)

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).
PRETREATMENT REQUIREMENTS
Any substantive or procedural requirement related to pretreatment, other than a national pretreatment standard imposed on an industrial user.
PRETREATMENT STANDARD or STANDARDS
Prohibited discharge standards, categorical pretreatment standards, and local limits.

b. 
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)).
2. 
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;
b. 
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
c. 
The industrial user never discharges any untreated concentrated wastewater discharge.
3. 
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.
