| This report provides updates on the status of optimization reviews conducted during fiscal year (FY) 2015 through FY 2017 and includes optimization-related technical support projects that were substantially completed through 2018. Optimization reviews typically identify several opportunities for improvements. These improvements are organized into five recommendation categories, remedy effectiveness, cost reduction, technical improvement, site closure, and energy and material efficiency. Project highlights demonstrate results achieved from optimization reviews and optimization-related technical support projects and exemplify how the optimization program applies and promotes best practices to improve site cleanup. |
