40 CFR 432.105 - New source performance standards (NSPS).

prev | next

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

Performance Standards


Maximum daily Maximum monthly avg.
Ammonia (as N) 1 0.14 0.07
BOD 51 0.18 0.09
Fecal coliform ( 2) ( 3)
O&G 1 4 0.10 0.05
Total Nitrogen 5 194 134
TSS 1 0.22 0.11

1 Pounds per 1000 lbs (or g/kg) of raw material (RM).

2 Maximum of 400 MPN or CFU per 100 mL at any time.

3 No maximum monthly average limitation.

4 May be measured as hexane extractable material (HEM).

5 mg/L (ppm).

(b) The standards for BOD5 and TSS specified in paragraph (a) of this section were derived for a renderer that does not cure cattle hide as part of the plant operations. If a renderer does cure hide, the same empirical formulas specified in § 432.107(b) should be used to calculate BOD5 and TSS limitations for process wastewater associated with cattle hide curing that apply in addition to the standards specified in paragraph (a) of this section.

(c) Any source that was a new source subject to the standards specified in § 432.105 of title 40 of the Code of Federal Regulations, 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) after which it must achieve the effluent limitations specified in §§ 432.103 and 432.107.
