In January 2005, the Northeast Ohio Regional Sewer District's (NEORSD's) Board of Trustees approved a long-term Residuals Management Plan for its three wastewater treatment plants. This Plan recommended replacement of the existing multiple hearth biosolids (sewage sludge) incinerators located at the Southerly WWTC with new state-of-the-art fluidized bed incinerators.

Southerly's fluidized bed incineration project originally consisted of the construction of a new Biosolids Handling and Incineration Facility to house three new fluidized bed incineration systems, nine new high solids dewatering centrifuges, and a biosolids truck loading facility.

Due to numerous retirements at the NEORSD (that resulted in a new Senior Staff, members of its Board of Trustees, Plant Superintendents and Operating personnel), NEORSD management personnel determined in June 2008 that the time was right to have an independent group of experts determine whether fluidized bed incineration was still the most viable, cost-effective way to manage Southerly's biosolids on a long-term basis.

This paper presents detailed information on the Independent Expert analyses, findings, and recommendations developed during a Validation Workshop.
