an engineering study evaluating alternatives to surface discharge. If no feasible alternatives to
dischargin are found by Beaufort County Elementary School, the limits for this permit will
change to 5,0 milligrams per liter for BODS and 1.0 milligram per liter for NH3 as during the
summer and 10.0 milligrams per liter for BODS and 1.8 milligrams per liter for NH3 as N during
the winter on March 1, 1995, due to the zero 7Q10 flow and the potential for ammonia toxicity in
the receiving stream.
