Sec. 417.23  Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best available technology 
          economically achievable.

    (a) The following limitations establish the quantity or quality of 
pollutants or pollutant properties, controlled by this section, which 
may be discharged by a point source subject to the provisions of this 
subpart after application of the best available technology economically 
achievable:
