New Jersey Administrative Code › Title 7 - ENVIRONMENTAL PROTECTION › Chapter 14A - NEW JERSEY POLLUTANT DISCHARGE ELIMINATION SYSTEM › Subchapter 13 - EFFLUENT LIMITATIONS FOR DSW PERMITS › Section 7:14A-13.16 - Point of compliance for effluent limitations

Current through Register Vol. 56, No. 14, July 15, 2024
(a) The point of
				compliance for each outfall shall be established as follows:
1. Permit effluent limitations, standards,
				prohibitions, and monitoring requirements shall be established for each outfall
				or discharge point of the permitted facility, except as provided under
				7:14A-6.2(b) 
				(BMPs where limitations are infeasible), (a)2 below (limitations on internal
				waste streams), (a)6 below (alternate monitoring point for whole effluent
				toxicity), and (a)7 below (discharges into storm sewers);
2. Effluent limitations or standards for
				discharges of pollutants may be imposed on internal waste streams before mixing
				with other waste streams or cooling water streams when:
i. Permit effluent limitations for the final
				effluent are impracticable or infeasible to calculate; or
ii. Monitoring of the final mixed effluent or
				point of discharge is impracticable or infeasible;
3. Internal monitoring points shall be
				established in cases where two or more different types of wastewater (for
				example, process waste, domestic waste, stormwater, non-contact cooling water)
				mix prior to entering the receiving water, unless such monitoring points are
				deemed to be unnecessary by the Department;
4. When the point of compliance is an
				internal waste stream, the monitoring required by
				7:14A-14.2 shall be applied to the
				internal waste stream;
5. When the
				point of compliance is an internal waste stream, the fact sheet under
				7:14A-15.8 shall set forth the
				circumstances which make such limitations necessary, such as that the final
				discharge point is inaccessible, the wastes at the point of discharge are so
				diluted as to make monitoring impractical, the interferences among pollutants
				at the point of discharge would make detection or analysis impracticable, or
				two or more waste streams are mixed prior to discharge;
6. For whole effluent toxicity, an alternate
				point of compliance may be established prior to chlorination if the permit
				includes water quality based limitations for chlorine produced oxidants and the
				following conditions are met:
i. The
				discharge is in compliance with the water quality based effluent limitations
				for chlorine produced oxidants at the point of discharge or such limitations
				have been determined to be unnecessary;
ii. A dechlorination treatment step is not
				required to attain the water quality based limitations for chlorine produced
				oxidants;
iii. Establishment of a
				monitoring point after chlorination at the point of discharge is impracticable
				or infeasible;
iv. Samples
				collected after chlorination are not able to attain the water quality based
				effluent limitation for whole effluent toxicity; and
v. The permittee demonstrates to the
				Department's satisfaction that the failure to attain the water quality based
				limitation in samples collected post-chlorination is due to the presence of
				chlorine produced oxidants in the effluent sample;
7. For discharges into stormwater
				conveyances, the point of compliance shall be established prior to the
				discharge into the stormwater conveyance, unless the Department determines on a
				site specific basis that an alternate point of compliance is
				appropriate.
8. For CPOs, an
				applicant or permittee may request a CPO decay factor for use within an
				approved regulatory mixing zone to adjust the measured effluent CPO
				concentration value in situations where the effluent has a significant period
				of travel time (more then 15 minutes during critical design conditions) between
				the location where the effluent CPO sample is taken and the point of discharge
				into the receiving waterbody.
