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 categorical 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
(b) 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. 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.
(2) 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 divisions (l)(b) or (1)(c) above but otherwise alters, replaces, or adds to existing process or production equipment.
(3) Construction of a NEW SOURCE as defined under this division has commenced if the owner or operator has:
(a) Begun, or caused to begin as part of a continuous on-site construction program:
1. Any placement, assembly, or installation of facilities or equipment; or

(b) Contributes a process wastestream which makes up 5% or more of the average dry weather hydraulic or organic capacity of the POTW treatment plant; or
(c) 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.
(3) Upon a finding that a user meeting the criteria in division (2) has no reasonable potential for adversely affecting the POTW's operation or for violating any applicable pretreatment standard or requirement, the city 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.
(4) The city may determine that an Industrial user subject to categorical pretreatment standards is a non-significant 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:
(a) The industrial user, prior to the city's finding, has consistently complied with all applicable categorical pretreatment standards and requirements;
(b) The industrial user annually submits the certification statement required in § 51.191(1) [see 40 CFR 403.12(q)], together with any additional information necessary to support the certification statement; and
