(2) "New source" means any of the following:
(a) 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 one of the following applies:
(i) The building, structure, facility, or installation is constructed at a site at which no other source is located.
(ii) The building, structure, facility, or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source.
(iii) 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.
(b) 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 paragraph (N)(2)(a)(ii) or (N)(2)(a)(iii) of this rule, but otherwise alters, replaces, or adds to existing process or production equipment.

Noncontact cooling water does not include any process waters or other types of wastewaters, nor is the water exposed to anything but the inside of the pipe. Noncontact cooling water should be reasonably free from contaminants like metals, ammonia, organics, and total dissolved solids so that discharge of noncontact cooling water to the POTW does not result in any of the following:

(c) Pass through of the POTW.
(4) "Non-significant categorical industrial user" is an industrial user subject to 40 C.F.R. chapter I, subchapter N, that the control authority may determine is a non-significant categorical industrial user, rather than a significant industrial user, on a finding that the industrial user does not discharge more than one hundred gallons per day (gpd) of total categorical wastewater (excluding sanitary, noncontact cooling, and boiler blowdown wastewater, unless specifically included in the categorical pretreatment standard) and all of 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.

(a) The Ohio EPA's or the POTW's approved long term control plan.
(b) The Ohio EPA's or the POTW's approved combined sewer system operation plan implementing the nine minimum controls.
