PART 437--THE CENTRALIZED WASTE TREATMENT POINT SOURCE CATEGORY--Table of Contents
 
                 Subpart B--Oils Treatment and Recovery
 
Sec. 437.20  Applicability.


    (a) Except as provided in Sec. 437.1(b), (c), or (d) or in paragraph 
(b) of this section, this subpart applies to that portion of the 
discharge of wastewater from a CWT facility that results from the 
treatment or recovery of oil from both oily wastes received from off-
site and other CWT wastewater associated with the treatment of, or 
recovery of oily wastes.
    (b) In order to ensure appropriate treatment rather than dilution of 
dissimilar wastes, an NPDES permit writer or control authority may 
require a new source or an existing source subject to this subpart to 
achieve alternative effluent limitations and standards, as defined in 
Sec. 437.2(b), in the following circumstances:
    (1) The facility receives, on a continuing basis, flows of process 
wastewater from five or fewer facilities subject to 40 CFR Subchapter N 
limitations and standards; and
    (2) The process wastewater flows received for treatment at the 
facility have relatively consistent pollutant profiles.
