                  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.
