Current through Register Vol. 56, No. 18, September 16, 2024
(a) Monitoring
requirements are as follows:
1. Samples and
measurements taken for the purpose of monitoring shall be representative of the
monitored activity.
2. The permittee
shall perform all analyses in accordance with the analytical test procedures
specified in 40 C.F.R. 136 or, in the case of residual use or disposal, in 40 C.F.R.
136 unless otherwise specified in 40 C.F.R. 503, or unless other test procedures
have been specified in the permit. Where no approved test procedure is available,
the permittee shall indicate a suitable analytical procedure and shall provide the
Department with literature references or a detailed description of the procedure.
The Department shall determine the appropriate procedure and require that procedure
in the NJPDES permit. The laboratory performing the analyses shall be certified by
the Department for the analysis of those specific parameters in accordance with
N.J.A.C. 7:18. Information concerning laboratory approval and/or certification may
be obtained from:
New Jersey Department of Environmental Protection
Office of Quality Assurance
PO Box 424
Trenton, New Jersey 08625-0424
(609) 292-3950
(b) All permittees shall:
1. Properly install, use, and maintain monitoring
equipment and use proper monitoring methods (including biological monitoring methods
when appropriate);
2. Properly monitor
the discharge in accordance with the monitoring type, interval, and frequency as
specified in the permit;
i. Certain discharges of
non-contact cooling water shall be exempt from monitoring, unless specifically
required by the Department, where the applicant's activities do not affect the
following constituents: COD, BOD, TSS, pH, and/or settleable solids.
ii. Bacterial monitoring shall not be required for
facilities which do not receive wastewater containing pathogenic organisms,
including fecal coliform, E. coli or enterococci organisms, unless otherwise
required by the Department;
3. Comply with the reporting requirements
specified in the permit; and
4. Monitor
in accordance with the edition of the Department's "Field Sampling Procedures
Manual" applicable at the time of sampling or an alternate method approved by the
Department.
(c) If the
Department has reason to believe that the accuracy and/or precision of one or more
analyses is inadequate to provide a reasonable estimate of effluent quality, the
Department shall, upon written notification, require any facility that analyzes its
effluent samples at a laboratory it directly or indirectly owns, operates or manages
to annually have one of its permit-required periodic sampling analyses performed by
a certified laboratory which is not owned, operated or managed by the permittee.
This shall be broadly construed to include all the sample analyses that are to be
performed during the course of routine hourly, daily, monthly, quarterly,
semi-annual, or annual sampling.
(d)
Requirements for automatically adjusting effluent monitoring frequency are as
follows:
1. Any permittee shall automatically
adjust its effluent monitoring and reporting frequency to monthly when the
permittee:
i. Reports effluent values that would
make the permittee a serious violator for one or more parameters for which the
permittee is required to report less frequently than monthly. Monthly reporting is
only required for parameters with serious violations. (However, NJPDES-SIU
permittees shall resample within 30 days of becoming aware of any violation if
required by 40 C.F.R. Part 403); or
ii.
Fails to submit a completed Discharge Monitoring Report (DMR).
2. The monthly reporting required by (d)1 above
shall begin the first month after the submission of the DMR or the month in which
the permittee was required to submit the completed DMR or the Baseline Report (BR)
to the Department which results in the permittee becoming a serious violator. If the
Department grants an affirmative defense pursuant to
7:14-8.3(i) for an
effluent violation, the violation shall not be considered a serious violation and
shall not be subject to monthly reporting under (d)1 above.
3. Any permittee required to adjust its monitoring
and reporting pursuant to (d)1 above shall continue this monthly schedule until the
permittee has submitted six consecutive monthly DMRs that show compliance with the
particular serious violation parameter at the particular discharge point, at which
time the permittee may resume the original schedule in its permit.
