                 Subpart C--Chemical Synthesis Products
 
Sec. 439.37  Pretreatment standards for new sources (PSNS).

    Except as provided in 40 CFR 403.7, any new source subject to this 
subpart must achieve the same standards as specified in Sec. 439.36.
    (a) Sources that discharge to a POTW with nitrification capability 
(defined at Sec. 439.2(i)) are not required to achieve the pretreatment 
standard for ammonia (as N).
    (b) The pretreatment standards for cyanide are as follows:

------------------------------------------------------------------------
                                                Effluent limitation \1\
                                             ---------------------------
                                                               Average
             Regulated parameter                 Maximum       monthly
                                                  daily       discharge
                                                discharge     must not
                                                               exceed

Cyanide (T).................................         33.5           9.4

\1\ Mg/L (ppm).

    (c) When monitoring for cyanide at the end-of-pipe is impractical 
because of dilution by other process wastewaters, compliance with the 
cyanide pretreatment standards in paragraph (b) of this section must be 
demonstrated at in-plant monitoring points pursuant to 40 CFR 403.6(e) 
(2) and (4). Under the same provisions, the permitting authority may 
impose monitoring requirements on internal wastestreams for any other 
parameter(s) regulated by this section.
    (d) Compliance with the standard in paragraph (b) or (c) of this 
section may be achieved by certifying to the permit issuing authority 
that a facility's manufacturing processes neither use nor generate 
cyanide.
