(c) The owner or operator of every water pollution control facility that receives a wastewater influent from more than one source shall determine and report on its NPDES permit application, required per 15A NCAC 02B .0105, the name and industrial classification number(s) for each applicable activity(ies) of every industrial establishment contributing wastes containing toxic substances, in toxic quantities, and also every industrial establishment contributing an average daily wastewater influent of one percent or more of the design flow of the facility or in excess of 100,000 gallons per day, whichever is less, and shall report such other information as is required by Rule .0505 of this Section; provided; however, that it is not required that the name and SIC or NAICS number of any source contributing domestic sewage influent only be reported hereunder.
