Subchapter 13 - EFFLUENT LIMITATIONS FOR DSW PERMITS
Section 7:14A-13.13 - Quantity of flow used in the determination of effluent limitations
Universal Citation: NJ Admin Code 7:14A-13.13
Current through Register Vol. 56, No. 24, December 18, 2024
(a) Effluent flows used for the determination of effluent limitations, standards, or prohibitions shall be established as described below:
1. Permit limitations for continuous
discharges shall be determined as follows:
i.
For DTWs, the design flow for the facility shall be used when determining
permit effluent limitations.
ii.
For non-DTWs, a reasonable measure of actual production of the facility, unless
otherwise required by an effluent guideline or effluent standard, shall be used
when determining effluent limitations. For new sources or new dischargers,
actual production shall be estimated using projected production. The time
period of the measure of production shall correspond to the time period of the
calculated permit limits (for example, monthly production shall be used to
calculate average monthly discharge limitations).
iii. The permit may include interim permitted
flows that are less than the final design flow to reflect the anticipated
effluent flow for the duration of the permit. The projected fifth year flow may
be used for DTWs in the determination of water quality based effluent
limitations applicable during periods prior to the facility utilizing the full
design flow.
2. Effluent
flow restrictions shall be included in discharge permits as permit conditions,
rather than as numerical effluent limitations, unless the Department determines
on a site specific basis that the quantity of effluent flow is of concern and
shall be included as a permit limitation. The Department shall state in the
permit fact sheet the reason(s) for such determination. The Department may
incorporate flow-related requirements necessary to implement the capacity
assurance or Treatment Works Approvals programs at N.J.A.C. 7:14A-22 and the
Statewide Water Quality Management Planning process at N.J.A.C. 7:15.
