NR 502.12(15)(a)1. 1. Samples of the finished compost that is ready for sale, distribution or use shall be collected every 2,000 tons or 4,000 cubic yards, with a minimum of one sample per year, or, alternatively, in accordance with the testing frequency specified by the United States Composting Council’s Seal of Testing Assurance program, unless a different frequency is approved in writing by the department, and tested for the parameters in Tables 1 and 2.

NR 502.12 Note Note: Only class A compost under sub. NR 502.12 (16) is subject to the limits in Tables 1 and 2. “Test Methods for Evaluation of Compost and Composting” (2002) and a list of laboratories certified under the Seal of Testing Assurance program are available from the United States Composting Council, 5400 Grosvernor Lane, Bethesda, Md 20814 [phone], www.compostingcouncil.org.
