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:
