Sec. 413.84  Pretreatment standards for existing sources.

    Except as provided in 40 CFR 403.7 and 403.13, any existing source 
subject to this subpart which introduces pollutants into a publicly 
owned treatment works must comply with 40 CFR part 403 and achieve the 
following pretreatment standards for existing sources (PSES):
    (a) No user introducing wastewater pollutants into a publicly owned 
treatment works under the provisions of this subpart shall augment the 
use of process wastewater or otherwise dilute the wastewater as a 
partial or total substitute for adequate treatment to achieve compliance 
with this standard.
    (b) For a source discharging less than 38,000 liters (10,000 gal) 
per calendar day of electroplating process wastewater the following 
limitations shall apply:
