[Amended 2-12-2020 by Ord. No. 2020.01.08-001]
The building, structure, facility or installation is constructed at a site at which no other source is located;

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.
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 A(2) or (3) of this definition but otherwise alters, replaces, or adds to existing process or production equipment.

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.
The discharge of pollutants through the POTW into navigable waters in quantities or concentrations which, alone or in conjunction with discharges from other sources, is a cause of a violation of any requirements of the POTW's National Pollutant Discharge Elimination System Permit, including an increase in magnitude or duration of a violation, or of applicable water quality criteria.
