Current through Register Vol. 56, No. 14, July 15, 2024
(a) Analyses shall
				be performed on the total sludge sample and shall be expressed on a bulk dry
				weight basis (mg/kg) except as otherwise specifically provided in the chapter
				Appendix, Tables I through VIII, incorporated herein by reference.
(b) The permittee shall perform all sludge
				analyses in accordance with the analytical test procedures specified in
				40 CFR
				503.8, incorporated herein by
				reference.
(c) Where an applicable
				laboratory method for sludge analysis is not provided for in
				40 CFR
				503.8, the analysis shall be conducted in
				accordance with the test procedures in "Test Methods for Evaluating Solid
				Waste," EPA Publication SW-846, incorporated herein by reference, including
				amendments and revisions. If an applicable approved test procedure is not
				specified in either
				40 CFR
				503.8 or EPA Publication SW-846, the domestic
				or industrial treatment works may use any appropriate method for sludge
				analysis for which a laboratory is certified by the Department's Office of
				Quality Assurance.
(d) Analyses
				conducted for the purpose of determining the formal waste classification of the
				sludge shall be performed in accordance with the requirements specified in
				N.J.A.C. 7:26G.
(e) All
				laboratories performing analyses under these rules shall perform and maintain
				all quality control data and records as required by N.J.A.C. 7:18. Laboratories
				shall follow the entire test procedure for sludge analyses specified in (b) and
				(c) above to completion without any modification. All quality control
				procedures as cited in the reference analytical techniques shall be performed
				and documented.
(f) All domestic
				and industrial treatment works shall retain records of the monitoring
				information, and quality assurance and quality control documentation specified
				below for a period of at least five years, or longer if required under N.J.A.C.
				7:14A-20, from the date of the sludge sample. The Department may, for cause,
				extend the period that the records must be maintained by written notice to the
				treatment works. Causes for extending the records maintenance period include,
				for example, enforcement action or litigation. All domestic and industrial
				treatment works shall maintain records of the following:
1. The date, exact place, and time of
				sampling or measurement;
2. The
				individual(s) who performed the sampling or measurement;
3. The weather conditions at the time of
				sampling and other observations which could potentially impact the laboratory
				analytical results;
4. The date(s)
				laboratory analyses were performed;
5. The individual(s) who performed the
				laboratory analyses;
6. The
				laboratory analytical techniques or methods used;
7. The results of such laboratory analyses;
				and
8. The following quality
				control and quality assurance information:
i.
				Method blank results;
ii. Serial
				dilution results for metal analyses;
iii. Precision and accuracy statement
				determined by laboratory matrix spikes and matrix spike duplicates on the
				sludge sample and the quality control sample;
iv. Chain-of-custody; and
v. Method detection limits (aqueous matrix
				and calculated for the sample based on dry weight).
