Biosolids Public Workshop March 22, 2016 Ken Cheek, Director Citrus County Water Resources

Overview In January, Staff were directed to research permitted Biosolids Land Application Sites (BLAS) located in Citrus County in response to odor complaints and environmental concerns received from neighboring property owners. Today’s Workshop will provide additional information to the Board and the Public regarding the land application of biosolids and septage in the County.

Definitions From 62-640.200, Florida Administrative Code (6) “Biosolids” means the solid, semisolid, or liquid residue generated during the treatment of domestic wastewater in a domestic wastewater treatment facility, formerly known as “domestic wastewater residuals” or “residuals.” Not included is the treated effluent or reclaimed water from a domestic wastewater treatment plant. Also not included are solids removed from pump stations and lift stations, screenings and grit removed from the preliminary treatment components of domestic wastewater treatment facilities, other solids as defined in subsection 62-640.200(31), F.A.C., and ash generated during the incineration of biosolids. Biosolids include products and treated material from biosolids treatment facilities and septage management facilities regulated by the Department. (41) “Septage” means a mixture of sludge, fatty materials, human feces, and wastewater removed during pumping of onsite sewage treatment and disposal systems. Excluded from this definition are the contents of portable toilets, holding tanks, and grease traps. Biosolids, which used to be called residuals, are the leftover waste product from the wastewater treatment process. This does not include the treated effluent, which is what goes to sprayfields onsite at the treatment plant or is discharged to public access reuse where permitted. It also does not include any material from lift stations, grit or screening from the wastewater plant, or other solids. Biosolids may also include material from septage management facilities. Septage is the waste product from originate from domestic or industrial septic or onsite sewage treatment and disposal systems.

Definitions From 62-640.200, Florida Administrative Code (7) “Biosolids management facility” means a biosolids treatment facility, a septage management facility regulated by the Department, or an application site. Biosolids Land Application Sites (BLAS) are Biosolids Management Facilities. (8) “Biosolids treatment facility” means a facility that treats biosolids from other facilities for the purpose of meeting the requirements of this chapter, before use or land application. Biosolids treatment facilities can also treat domestic septage and combinations of biosolids, domestic septage, food establishment sludges, wastes removed from portable toilets, and wastes removed from holding tanks associated with boats, marinas, and onsite sewage treatment and disposal systems, before use or land application. (42) “Septage management facility” means a stationary facility that treats only domestic septage or combinations of domestic septage, food establishment sludges, wastes removed from portable toilets, and wastes removed from holding tanks associated with boats, marinas, and onsite sewage treatment and disposal systems, before use or land application. Septage management facilities that are regulated by the Department are as described in paragraph 62-640.100(5)(c), F.A.C. A Biosolids Management Facility, or BMF, is a site where biosolids may be land applied. Biosolids Land Application Sites are BMFs. A Biosolids Treatment Facility, or BTF, treats biosolids from other facilities prior to land application. BTFs can treat wastewater treatment biosolids as well as septage. Septage Management Facilities may only land apply treated septage.
