Section 7:14A-14.3 - Monitoring frequency requirements for NJPDES-SIU permits

(a) This section establishes monitoring requirements for SIU permits issued by the Department. Monitoring frequency for each parameter shall be determined based on the following factors:

1. The permittee's compliance history;

2. The impact of the discharge on the receiving local agency's treatment process, discharge and/or sludge quality or potential for endangerment to public health or to the local agency employee's health or safety;

3. The volume (or mass) of the discharge(s);

4. Production variations (variability of the discharge); and

5. Any Federal or local requirements regarding significant indirect users.

(b) Monitoring frequency shall be reduced if a permittee submits a written request to the Department demonstrating that compliance for the affected parameter(s) has been achieved for a minimum period of one year. Monitoring frequency shall be reduced as follows:

1. From weekly to monthly;

2. From twice monthly to monthly;

3. From monthly to quarterly; or

4. From quarterly to semi-annually.

(c) Notwithstanding (b) above, in accordance with 40 CFR 403.12(g), whenever a permittee becomes aware of a permit violation, the permittee shall resample within one month unless the monitoring schedule established in the permit requires sampling sooner, in which case the permittee shall resample in accordance with such monitoring schedule. Upon written notice from the Department, the permittee shall resume the former, more frequent monitoring and reporting schedule unless the permittee demonstrates that the exceedence was caused by an upset, bypass or laboratory error as provided for in 7:14A-6.11.
