Sec. 432.22  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 effluent limitations:
    (1) 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:

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 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 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 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
