The Director may deny or condition new or increased contributions of pollutants, or changes in the nature of pollutants, to the POTW by industrial users where such contributions do not meet applicable National Pretreatment Standards and requirements, where such contributions would cause the POTW to violate its NPDES permit, or where such contributions exceed the reserve treatment capacity of the POTW.
