a. Evaluation of the feasibility and costs of biosolids disposal alternatives should land application cease, including landfilling, third-party composting, and incineration. b. An evaluation of the impact that moving to 100% dewatering would have on the liquid process, including recommended dewatering, thickening, and sidestream treatment equipment costs, operational costs, and non-cost factors. c. Coordination as needed with the assumptions and output of ongoing studies being performed by HDR, which include a Carbon Study and Fermentation Capacity Evaluation, an Ammonia-Based Aeration Control (ABAC) Pilot, and an Equalization and Hydrograph Study. d. An update on the current state of development of several advanced treatment options evaluated in the Master Plan known to be capable of removing PFAS from biosolids, including gasification, pyrolysis and super critical water oxidation, and updated cost estimates for these options. e. Analysis and logistical support related to potential pilot testing of advanced treatment options.
