Minnesota rules identify 16 standing beneficial uses for which waste generators or end users can simply follow the applicable rules without contacting the MPCA. Only the specific solid wastes and uses designated in the rule have this status. Organizations that propose other uses for solid waste must seek approval for a case-specific beneficial use determination or demonstration/research project.

Definitions
Uncontaminated material does not contain or carry substances that may be harmful to human health and the environment. For example, concrete painted with lead-based paint may be contaminated, while concrete painted with non-toxic latex paint is uncontaminated.
Unadulterated wood is defined as "wood that does not contain contaminants present as a result of manufacturing or use of the wood," such as paints, varnishes, stains, glues, resins or chemicals used to prevent rotting. Unadulterated newspaper must not contain contaminants from prior use (e.g., used to soak up oil).
