N.J. Admin. Code § 7:14C-1.4

Current through Register Vol. 56, No. 24, December 18, 2024

Section 7:14C-1.4 - Analytical procedures

(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).

(g) The Department may require domestic or industrial treatment works to submit the information in (f) above if the Department, in reviewing SQAR reports or other relevant information, determines that the data reflect unusually high or low reported pollutant concentrations.

(h) All sludge analyses required under this chapter shall be performed by laboratories certified by the Department pursuant to N.J.A.C. 7:18 for the analytical procedures specified in (b) and (c) above.
