An existing animal feeding operation may not expand if its livestock waste control facility is located within one mile of a designated cold water class A stream segment delineated pursuant to Neb. Rev. Stat. § 54-2421, and in the same cold water class A stream watershed as the animal feeding operation, except that an existing animal feeding operation used for research sponsored by the University of Nebraska at a facility owned by the University of Nebraska may expand if the Department determines, based on scientific information provided in the application or other available scientific information, that the proposed expansion does not pose a potential threat to the stream.
