130 Neb. Admin. Code, ch. 1, § 031
"National Pollutant Discharge Elimination System (NPDES) permit" means either a general permit or an individual permit, issued by the Department pursuant to Subsection 11 of Neb. Rev. Stat. § 81-1505. A general permit authorizes categories of disposal practices or livestock waste control facilities and covers a geographic area corresponding to existing geographic or political boundaries, though it may exclude specified areas from coverage. General permits are limited to the same or similar types of animal feeding operations or livestock waste control facilities which require the same or similar monitoring and, in the opinion of the Director of the Department of Environmental Quality, are more appropriately controlled under a NPDES general permit than under an individual permit.
