N.J. Admin. Code § 7:14A-13.16 - Point of compliance for effluent limitations

(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.
