He <br />apologized that he didn’t call prior to the meeting so that he <br />could be sure to have all the answers pertaining to the <br />questions they would have included in the Power Point. Mr. <br />Severtson’s presentation outlined what biosolids are, how they <br />are regulated and what their use in agriculture is. He stated <br />there are a lot of misconceptions about what biosolids. He <br />stated that what they are is the solids removed from wastewater <br />plants that are dewatered and tested for pollutants and <br />pathogens. He explained that the mechanism for treating sewage <br />is biological – using managed aquatic bacterial populations and <br />that the bacteria consumes the solids in raw sewage as a food <br />source, (aerobic digestion w/water; anaerobic digestion w/o <br />oxygen). He stated that once those steps are complete (consuming <br />and digesting the solids), the bacterial biomass is settled out <br />of the wastewater. He reviewed picture slides of typical <br />biosolids storage site, belt filter press, bristleworm & <br />waterbear as well as rotifers and an aeration basin & clarifier. <br />Mr. Severtson reviewed the biosolids regulation in Washington <br />(WAC 173-308). Mr. Severtson reviewed the basic elements of <br />Washington’s biosolids Rule WAC-173-308. He stated that the <br />Department of Ecology may issue a single Statewide General <br />Permit for biosolids Management. He explained that Producers and <br />those who land apply biosolids are issued permit coverage under
