Code of Federal Regulations Title 40. Protection of Environment § 40.432.42 Effluent limitations attainable by the application of the best practicable control technology currently available (BPT)

(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:

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. A djustments 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 § 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 § 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 § 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 § 432.12(a)(5) apply.

(1) All facilities must achieve the following effluent limitations for ammonia (as N):

¹ mg/L (ppm).

(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.
