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:
Effluent Limitations
[BPT]
Regulated parameter | Maximum daily1 | Maximum monthly avg.1 |
BOD52 | 0.48 | 0.24 |
Fecal Coliform | (3) | (4) |
O&G5 | 0.26 | 0.13 |
TSS2 | 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).
Effluent Limitations
[BPT]
Regulated parameter | Maximum daily1 | Maximum monthly avg.1 |
Ammonia (as N) | 8.0 | 4.0 |
1 mg/L (ppm).
