		3.	The production of 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 sources, 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 subsection A2 or 3 of this definition but otherwise alters, replaces, or adds to existing process or production equipment.

J. Copper-Based Chemical Compounds:

1. No person shall discharge, or cause, allow or suffer to be discharged, any chemical compound containing greater than five percent (5%) copper by weight, to control roots, or for any other purpose, into the sanitary sewer system or any part thereof, or into any plumbing fixture or sewer which discharges, either directly or indirectly, into the sanitary sewer system.
