“Pretreatment Facility” means a facility which provides reduction of the amount of pollutants, elimination of pollutants or the alteration of the nature of pollutant properties in wastewater prior to or in lieu of discharging or otherwise introducing such pollutants into a publicly owned treatment works (POTW) or other treatment system not owned by the facility.
“Primary Source Water Protection Area” means the surface-water flow system and drainage area upstream of an existing or proposed public water system intake, delineated by the Department as the in-stream twenty four (24) hour time of travel distance for the ten (10) percent exceedance flow (i.e., primary source water protection area).
“Private Entity” means any private corporation, association, partnership, corporation, industry, copartnership, firm, trust, estate, any other legal entity whatsoever, or an agent or employee thereof.
