Section 7:14A-13.18 - Inclusion of action levels for water quality based effluent limitations
Current through Register Vol. 56, No. 18, September 16, 2024
(a) Where the Department has developed water quality based effluent limitations utilizing a chemical equilibrium which includes non-limited pollutants or pollutant parameters which control the chemical equilibrium, action levels for the controlling pollutants or pollutant parameters equal to the values used in the chemical equilibrium calculation shall be included in the permit as permit monitoring conditions.
(b) For ammonia-N limitations, action levels shall be determined and included for pH and may be included for temperature, alkalinity or hardness.
(c) For those metals where the applicable criterion is dependent on hardness, an action level shall be included for hardness.
(d) If the discharge is not in conformance with the applicable action level for a period of time not to exceed the duration of the applicable criterion, the permittee shall take the specific actions stipulated in the discharge permit. These actions may require the permittee to:
(e) If the action levels set forth in the permit are exceeded more frequently than once in any monthly monitoring period, the action levels shall be re-evaluated and, if necessary, the effluent limitations associated with those action levels shall be recalculated. The permit shall be reopened and modified to include the updated effluent limitations and the associated action levels. The permit shall be reopened and modified to adjust the action levels and/or the effluent limitations if monitoring data demonstrate that the discharge causes, contributes, or has the reasonable potential to cause or contribute to an exceedance of the surface water quality standards at N.J.A.C. 7:9B.
(f) The following concern whole effluent toxicity (WET) action levels:
