Appendix A Scope of Work As a follow up to the previously conducted operational evaluation for nutrient removal, where evidence of inconsistent, and periodically high organic loading rates was identified, CH2M will perform a second operations and maintenance (O&M) technical review of the West Regional WRF for Indian River County, Florida. The review will focus on the sources of nutrient loadings, especially within the biosolids facility, and identify other potential sources outside the facility. CH2M's technical review services shall be provided by a Senior Operations Specialist and two Process Engineers. The scope will include: I. Data request and review. CH2M requests that any applicable plant data be forwarded to us for preliminary review of existing plant conditions which provides for greater efficiency of time on the plant site. 2. In field evaluation. Three (3) days of onsite time, plus travel and preparations, will be provided by the Senior Operations Specialist and two Process Erlfgineers specializing in Wastewater and Biosolids Treatment, respectively. We assume that client staff will be available during the site visit to answer questions, provide tours the plant, and supply data as needed. 3. Analysis. CH2M will review provided data and field notes, including regulatory correspondence, process control data and compliance data, and any operating procedures that appear relevant to the evaluation. 4. Meetings and discussions. CH2M will present preliminary findings to plant staff for discussion before composing the technical memorandum. This discussion will include the results from the initial review conducted by CH2M. 5. Technical memorandum (TM). CH2M shall provide written recommendations to improve procedures for reducing nutrient concentrations in the facility's final effluent or for additional tasks that address the extreme loading issues at the WRWRF. Recommended improvements are expected to consider biological and/or chemical treatment options and/or equipment/process system operation changes. The TM will be provided within seven (7) business days of the last day onsite. The project total fee will be a lump sum of $29,900 for the services described in this scope of work. Any additional labor required will be approved by Indian River County prior to CH2M commencing work. A single invoice will be submitted for this project. Schedule The project is expected to be initiated within two weeks of authorization and completed within one month of receipt of this signed agreement, to allow both CH2M and Client staff to find an appropriate and mutually agreeable week for the onsite evaluation, and to complete the TM. Some tasks rely on IRC to provide information and may require testing and laboratory analysis, which will have a bearing on successful project completion. If the project is delayed due to external reasons, the Project Manager will communicate this to the and develop revised schedules, if necessary. FORM 124 REVISED: 11109 P72
