Universal Citation: NJ Admin Code 7:14A-6.17

Current through Register Vol. 56, No. 18, September 16, 2024

(a) When part of a discharger's process wastewater is not being directly discharged into surface waters of the State or contiguous zone because it is disposed into a well, into a DTW, or by land application thereby reducing the flow or level of pollutants being discharged into surface waters of the State, applicable effluent standards or limitations for the discharge in a NJPDES permit shall be adjusted to reflect the reduced raw waste resulting from such disposal.

(b) Effluent limitations and standards in the permit shall be calculated by one of the following methods:

1. If none of the waste from a particular process is discharged into waters of the State, and effluent limitation guidelines provide separate allocations for waste from that process, all allocations for the process shall be eliminated from calculation of permit effluent limitations or standards;

2. In all cases other than those described in (b)1 above, effluent limitations shall be adjusted by multiplying the effluent limitation guidelines to the total waste stream by the amount of wastewater flow to be treated and discharged into surface waters of the State and dividing the result by the total wastewater flow. Effluent limitations and standards so calculated may be further adjusted under 40 CFR Part 125, Subpart D, to make them more stringent if discharges to wells, DTWs, or by land application change the character or treatability of the pollutants being discharged to receiving waters.
i. This method may be algebraically expressed as:
(1) P = E x N/T

(where: P is the permit effluent limitation,

E is the limitation derived by applying effluent guidelines to the total waste stream,

N is the wastewater flow to be treated and discharged to surface waters of the State, and

T is the total wastewater flow).

(c) Subsection (a) above shall not apply to the extent that promulgated effluent limitation guidelines:

1. Control concentrations of pollutants discharged but not mass; or

2. Specify a different specific technique for adjusting effluent limitations to account for well injection, land application, or disposal into DTWs.

(d) Subsection (a) above does not alter a discharger's obligation to meet any more stringent requirements established under this chapter.
