# §432.45. New source performance standards (NSPS).


Except as provided in [paragraph (c)](#c) of this section, any source that is a new source subject to this subpart must achieve the following performance standards:

- (a) Facilities that slaughter no more than 50 million pounds per year (in units of LWK) must achieve the following performance standards:
  - (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, the standards for BOD5, fecal coliform, TSS, and O&G are the same as the limitations specified in [§ 432.42(a)(1)](/cfr/40/432.42.md?p=a-1); and standards for ammonia (as N) are as follows:
  - (2) In addition to the standards specified in [paragraph (a)(1)](#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)](/cfr/40/432.12.md?p=a-3) and the standards for ammonia (as N) specified in [§ 432.15(a)(2)](/cfr/40/432.15.md?p=a-2) apply.
  - (3) In addition to the standards specified in [paragraph (a)(1)](#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)](/cfr/40/432.12.md?p=a-4) and the standards for ammonia (as N) specified in [§ 432.15(a)(3)](/cfr/40/432.15.md?p=a-3) apply.
  - (4) In addition to the standards specified in [paragraph (a)(1)](#a-1) 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 [§ 432.12(a)(5)](/cfr/40/432.12.md?p=a-5) and the standards for ammonia (as N) specified in [§ 432.15(a)(4)](/cfr/40/432.15.md?p=a-4) apply:
- (b) Facilities that slaughter more than 50 million pounds per year (in units of LWK) must achieve the following performance standards:
  - (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, the standards for BOD5, fecal coliform, TSS, and O&G are the same as the limitations specified in [§ 432.42(a)(1)](/cfr/40/432.42.md?p=a-1); and standards for ammonia (as N) and total nitrogen are the same as the limitations specified in [§ 432.15(b)(1)](/cfr/40/432.15.md?p=b-1).
  - (2) In addition to the standards specified in [paragraph (b)(1)](#b-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 standards for BOD5 and TSS specified in [§ 432.12(a)(3)](/cfr/40/432.12.md?p=a-3) apply.
  - (3) In addition to the standards specified in [paragraph (b)(1)](#b-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 standards for BOD5 and TSS specified in [§ 432.12(a)(4)](/cfr/40/432.12.md?p=a-4) apply in addition to the standards specified in [paragraph (b)(1)](#b-1) of this section.
  - (4) In addition to the standards specified in [paragraph (b)(1)](#b-1) 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 standards for BOD5 and TSS specified in [§ 432.12(a)(5)](/cfr/40/432.12.md?p=a-5) apply.
- (c) Any source that was a new source subject to the standards specified in § 432.45 of [title 40 of the Code of Federal Regulations](/cfr/40.md), revised as of July 1, 2003, must continue to achieve the standards specified in this section until the expiration of the applicable time period specified in [40 CFR 122.29(d)(1)](/cfr/40/122.29.md?p=d-1) after which it must achieve the effluent limitations specified in §§ [432.42](/cfr/40/432.42.md) and [432.43](/cfr/40/432.43.md).
