Wisconsin Administrative Code › Department of Natural Resources › NR 200-299 - Environmental Protection - Wisconsin Pollutant Discharge Elimination System › Chapter NR 219 - Analytical Test Methods And Procedures › Section NR 219.04 - Identification of test procedures

Current through June 24, 2024
(1) ANALYTICAL TEST
				PROCEDURES. Parameters or pollutants, for which wastewater analytical methods
				are approved, are listed together with test procedure descriptions and
				references in tables A to H. Parameters or pollutants, for which sludge
				analytical methods are approved, are listed together with test procedure
				descriptions and references in table EM. The discharge values for the listed
				parameters shall be determined by one of the standard analytical test
				procedures identified in a table under this subsection or by an alternate test
				procedure established under ss. NR 219.033 and 149.42.
Note:
The laboratory performing the analyses on
				  any samples will be certified for the applicable PFAS compounds in aqueous,
				  sludge (biosolids), and tissue matrices in accordance with s. NR 149.41 by the
				  Wisconsin Laboratory Certification Program established under s.
				  299.11,
				  Stats. If the EPA Office of Water publishes a final approved 1600 series
				  isotope dilution method for the analysis of PFAS in aqueous, sludge
				  (biosolids), and tissue matrices, the department recommends use of the final
				  approved EPA method.
(2)
				SAMPLE PRESERVATION PROCEDURES. Sample preservation techniques, container
				materials, and maximum allowable holding times for parameters identified in
				tables A to H are prescribed in table F. Sludge samples shall be preserved at
				the time of collection by cooling to less than or equal to 6°C where
				required. All samples requiring thermal preservation at less than or equal to
				6°C shall be cooled immediately after collection, and the required
				temperature maintained during shipping. Any person may apply for a variance
				from the prescribed preservation procedures applicable to samples taken from a
				specific discharge. Applications for variances may be made by letters to the
				regional administrator and shall provide sufficient data to assure that the
				variance does not adversely affect the integrity of the sample. The regional
				administrator will make a decision on whether to approve or deny a variance
				within 90 days of receipt of the application.
(3) TEMPERATURE REPORTING PROCEDURES. Samples
				cooled with ice packs or not in direct contact with ice during shipping shall
				be cooled to less than or equal to 6° C prior to shipping, and a
				temperature blank shall be submitted with the samples. Samples cooled during
				shipping with ice packs may not be recorded as received on ice. Samples may be
				recorded as received on ice only if solid ice is present in the cooler at the
				time the samples are received. If the samples are not received on ice, the
				laboratory shall record one of the following at the time of receipt:
(a) The temperature of an actual
				sample.
(b) The temperature of a
				temperature blank shipped with the samples.
(c) The temperature of the melt water in the
				shipping container.
