N.J. Admin. Code § 7:14A-14.2 - Monitoring frequency requirements for direct surface water discharges

(a) A monitoring schedule for parameters included in a DSW permit shall be established as provided in Tables 14-1 through 14.4 below. Tables 14-2 and 14-4 establish monitoring frequencies for parameters in DSW permits that are either monitored and limited, or monitored only. Tables 14-1 and 14-3 establish monitoring frequencies in DSW permits that are monitored and limited.

(b) The monitoring frequency for any parameter or group of parameters will be increased for a specific discharger if the Department determines that increased monitoring frequency is appropriate based on factors such as effluent variability, non-compliance history, or other site specific factors. The Department shall describe the reasons for the increased monitoring in the draft permit fact sheet.

(c) The monitoring frequency for any parameter or group of parameters will be decreased when:

1. An existing discharge permit specifies less frequent monitoring than is specified in this section, the reduced monitoring frequency will be continued in the renewed permit provided the discharger has demonstrated consistent compliance with the specified parameters;

2. A permit specifies conditions for monitoring frequency reduction and the permittee complies with all conditions; or

3. A permittee requests a reduction in compliance monitoring frequency during the time that the permittee is engaged in a watershed TMDL study in cooperation with the Department and/or other dischargers and the Department considers the change warranted. The monitoring frequency reduction will be effected as a major modification of the discharge permit in accordance with 7:14A-16.4(b)20. This provision does not affect the Department's authority to require ambient monitoring as part of the permit application or as a permit condition.

(d) Notwithstanding any reduction in monitoring frequency established pursuant to (c) above, whenever a Discharge Monitoring Report shows that an effluent limitation has been exceeded, the applicable monitoring frequency shall be adjusted as follows:

1. A permittee shall adjust monitoring to monthly for serious violations in accordance with 7:14A-6.5(d).

2. For violations which are not serious violations the permittee shall, upon written notice from the Department, resume the monitoring frequency established immediately preceding the frequency reduction and reporting schedule unless the permittee can demonstrate to the satisfaction of the Department that the exceedence was caused by an upset, bypass or laboratory error as provided for in 7:14A-6.11.

(e) General permits and individual stormwater discharge permits are exempt from the requirements of this section unless the fact sheet for the draft general or stormwater discharge permit contains a summary of the basis for imposing monitoring in accordance with 7:14A-15.8(c)4.
