Subpart D_High-Processing Packinghouse
Sec. 432.42 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 the
slaughtering of animals on-site or the processing of the carcasses of
animals slaughtered on-site:
Effluent Limitations
[BPT]
------------------------------------------------------------------------
Maximum
Regulated parameter Maximum monthly
daily \1\ avg. \1\
------------------------------------------------------------------------
BOD5 \2\...................................... 0.48 0.24
Fecal Coliform................................ (\3\) (\4\)
O&G \5\....................................... 0.26 0.13
TSS \2\....................................... 0.62 0.31
------------------------------------------------------------------------
\1\ Pounds per 1000 lbs (or g/kg) LWK.
\2\ The values for BOD5 and TSS are for average plants, i.e., plants
where the ratio of avg. wt. of processed meat products/avg. LWK is
0.55. Adjustments can be made for high-processing packinghouses
operating at other such ratios according to the following equations:
lbs BOD5/1000 lbs LWK = 0.21 + 0.23 (v--0.4) and lbs TSS/1000 lbs LWK
= 0.28 + 0.3 (v--0.4), where v equals the following ratio: lbs
processed meat products/lbs LWK.
\3\ Maximum of 400 MPN or CFU per 100 mL at any time.
\4\ No maximum monthly average limitation.
\5\ 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 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 limitations
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, TSS, and O&G 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
locations off-site, the limitations for BOD5 and TSS
specified in paragraph (a)(3) of this section apply.
(5) In addition to the limitations specified in paragraphs (b)(1)
and (2) 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 paragraph (a)(4) of this section
apply.
(6) In addition to the limitations specified in paragraphs (b)(1)
and (2) 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 paragraph (a)(5) of this section apply.
