Determination of the Long Term Feasibility of Transporting Unstabilized North Olmsted Biosolids to the North Royalton Composting Facility and Composting the transported biosolids with Unstabilized North Royalton Biosolids Pilot Test Plan of Study Revision No. I 4. Determine the ability of the existing North Royalton compost sales program to dispose of the additional compost volume generated by the processing of unstabilized North Olmsted biosolids at the North Royalton composting facility; 5. Determine the long -term ability of the North Royalton composting facility to produce Class A EQS biosolids over a five year period; and 6. Confirm the expected economics of both municipalities. The work completed since April 2001 has provided sufficient and satisfactory information to make positive determinations for items 1 through 5 above. However, additional pilot testing work is needed to generate cost data in order to provide sufficient and satisfactory information for item 6. III. PILOT TEST PLAN OF STUDY The Plan of Study includes two groups (i.e. tasks) of activities. The first group of activities is a two -week data collection period during which the long term economic and technical feasibility of the pilot test would be determined. The second group of activities would be those required to show to the economical and technical feasibility of a long- term effort and to obtain administrative approvals by the legislative bodies of both municipalities and by the Ohio EPA if it is economically and technically feasible to do SO. The Task 1 activities are those needed to generate the data and information necessary to determine if it is economically and technically feasible for the City of North Olmsted to transport unstabilized biosolids to the City of North Royalton composting facility for stabilization by the City of North Royalton. Therefore, the Task 1 activities will define the. technical boundaries of any such long -term operation based on the following: 1. The current wastewater treatment staffing levels of both municipalities; 2. The current biosolids treatment capabilities at the wastewater treatment plants operated by both municipalities; 3. The current biosolids transportation capabilities of the City of North Olmsted; 4. The capabilities of the current City of North Royalton compost sales program to dispose of additional quantities of stabilized biosolids; 5. The confirmation of the long -term operation and cost assumptions of both municipalities that led to the undertaking of the pilot test. CompostPOS- Revl.doc Page 3 of 6 September 6, 2001
