Sec. 432.32  Effluent limitations attainable by the application of the best practicable 
control technology currently available (BPT).

    Except as provided in 40 CFR 125.30 through 125.32, any existing 
point source subject to this subpart must achieve the following effluent 
limitations representing the application of BPT:
    (a) Facilities that slaughter no more than 50 million pounds per 
year (in units of LWK) must achieve the following limitations:
    (1) In the case of process wastewater associated with slaughtering 
of animals on-site or the processing of the carcasses of animals 
slaughtered on-site:

\3\ No maximum monthly average limitation.
\4\ May be measured as hexane extractable material (HEM).

    (2) In addition to the limitations specified in paragraph (a)(1) of 
this section, in the case of process wastewater associated with the 
processing (defleshing, washing and curing) of hides derived from 
animals slaughtered at locations off-site, the limitations for 
BOD5 and TSS specified in Sec. 432.12(a)(2) apply.
    (3) In addition to the limitations specified in paragraph (a)(1) of 
this section, in the case of process wastewater associated with the 
processing of blood derived from animals slaughtered at locations off-
site, the limitations for BOD5 and TSS specified in Sec. 
432.12(a)(3) apply.
    (4) In addition to the limitations specified in paragraph (a)(1) of 
this section, in the case of process wastewater associated with the wet 
or low-temperature rendering of material derived from animals 
slaughtered at locations off-site and dead animals, the limitations for 
BOD5 and TSS specified in Sec. 432.12(a)(4) apply.
    (5) In addition to the limitations specified in paragraph (a)(1) of 
this section, in the case of process wastewater associated with the dry 
rendering of material derived from animals slaughtered at locations off-
site and dead animals, the limitations for BOD5 and TSS 
specified in Sec. 432.12(a)(5) apply.
    (b) Facilities that slaughter more than 50 million pounds per year 
(in units of LWK) must achieve the following limitations:
    (1) All facilities must achieve the following effluent limitation 
for ammonia (as N):

    (2) In the case of process wastewater associated with the 
slaughtering of animals on-site or the processing of the carcasses of 
animals slaughtered on-site, the limitations for BOD5, fecal 
coliform, O&G, and TSS are the same as the corresponding limitations 
specified in paragraph (a)(1) of this section.
    (3) In addition to the limitations specified in paragraphs (b)(1) 
and (2) of this section, in the case of process wastewater associated 
with the processing (defleshing, washing and curing)

of hides derived from animals slaughtered at locations off-site, the 
limitations for BOD5 and TSS specified in paragraph (a)(2) of 
this section apply.
    (4) In addition to the limitations specified in paragraphs (b)(1) 
and (2) of this section, in the case of process wastewater associated 
with the processing of blood derived from animals slaughtered at
