Non-Exceptional Quality Biosolids Non-exceptional quality biosolids are biosolids that meet specified pollutant and pathogen reduction criteria. Criteria for non-exceptional quality biosolids are less stringent than criteria for exceptional quality biosolids.
Note: The term 'Biosolids' can be used to refer to all categories of biosolids collectively, or can be used to refer specifically to the category non-exceptional quality biosolids.
