N.J. Admin. Code § 7:14A-24.9 - Monitoring requirements for certain stormwater discharges

(a) For small municipal separate storm sewer systems, and for stormwater discharges associated with industrial activity or small construction activity that are not subject to an effluent limitation guideline that establishes monitoring requirements or numeric effluent limitations, monitoring requirements shall be established on a case-by-case basis depending upon the nature and effect of the discharge. The permittee shall be required to monitor such discharges in accordance with 7:14A-11.2(a)2, or, at a minimum:

1. For small municipal separate storm sewer systems subject to 7:14A-25.6 or 25.8, the permittee shall comply with the requirements for evaluation, recordkeeping, and reporting in 7:14A-25.6(j) or 25.8(i), respectively.

2. For stormwater discharges associated with industrial activity or small construction activity:

i. The permittee shall conduct an annual inspection of the facility to identify areas contributing to a stormwater discharge associated with industrial activity or small construction activity and evaluate whether measures to reduce pollutant loadings identified in a stormwater pollution prevention plan are adequate and properly implemented in accordance with the terms of the permit or whether additional control measures are needed;

ii. The permittee shall prepare a report summarizing the result of the annual inspection conducted under (a)2i above. This report shall be accompanied by an annual certification that the facility is in compliance with its stormwater pollution prevention plan and the permit, except that if there are any incidents of non-compliance, those incidents shall be identified in the certification. If there are incidents of non-compliance, the report shall identify the steps being taken to remedy the non-compliance and to prevent such incidents from recurring. The permittee shall maintain this report and certification for a period of at least five years from the date of the report. This period may be extended by written request from the Department at any time; and

iii. Such report and certification shall be signed by a person described in 7:14A-4.9.

iv. Permittees that are not required to submit monitoring reports at least annually pursuant to this subsection shall report to the Department at least annually all instances of non-compliance not reported under 7:14A-6.7, 6.8 and 6.10.

(b) The operating entity for a large or medium municipal separate storm sewer system shall include, in its annual report, a summary of data, including monitoring data, that is accumulated throughout the reporting year, in accordance with 7:14A-25.10(b) and 40 C.F.R. 122.42(c).
