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.
Public Entity means organizations such as a city, town, county, municipality, or special purpose sewer district.
