Specifications include, but are not limited to: The scope of services for this study includes evaluating the availability of sufficient and consistent amounts of bulking agents available to support continued acceptance of the current levels of municipal biosolids and other wet wastes at JRL after July 1, 2025. In July 2025, the restrictions on out-of-state waste and recycling requirements for certain large solid waste processing facilities will go back into effect (see Public Law 2023, Chapter 283) which could limit the amount of bulking agents available for use at JRL. The study must include the following: 1. A comprehensive list of materials that can be effectively used to bulk municipal biosolids and other wet wastes with emphasis on material availability in Maine. The material list should include: (a) Material type, source, and geographic location. (b) A discussion of each material’s physical, chemical, and engineering properties, including any characteristics that may impact its compatibility with municipal biosolids at disposal facilities, as applicable. (c) A discussion of each material’s compatibility with typical engineered liner systems and other engineered components within a secure solid waste landfill. (d) Cost of each material in dollars per ton and cost per cubic yard (or ton) to transport to JRL. (e) Approximate quantities of each material available. (f) Availability of material (constant source, one time source, etc. (g) Any public benefits of the material being used as a bulking agent in a landfill (cleaning up a problem, etc.) with cost analysis. 2. An evaluation of the effectiveness and performance of each material in achieving a stable waste surface for the operation of typical landfill equipment. Approximate ratios of bulking materials to municipal biosolids assuming a typical solids content ranging from 18 to 20 percent needed to achieve stability should be provided. 3. An evaluation of the seasonal fluctuations of each material including approximate timeframes in which each material is generally available. 4. Submission of a draft report for Department of Administrative and Financial Services and Department of Environmental Protection review and comment. 5. Submission of a draft report by November 1, 2024, and submit final report by December 1, 2024, incorporating the above noted information.
