Identification of test procedures

Identification of test procedures. (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 . (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. (4) Incorporation by reference. The materials in this section are incorporated by reference for the purposes of the permit program under ch. 283 , Stats.
