(2) A person who proposes to separate a waste for use as compost shall file a petition with the director pursuant to the provisions of R 299.4118a. To characterize such compost, the petitioner shall include all of the following information in the petition: (a) The type of waste and its potential for creating a nuisance or environmental contamination.

The weight of the separated foreign matter divided by the weight of the total sample multiplied by 100 shall be the foreign matter content. (d) Particle size, as determined by a sieve analysis.
