DELAWARE ESTUARY RSM WORKGROUP

RSM Plan  Comprehensive long-term master plan to address the economic

and environmental benefits and long long-term term needs of sediment quality, sediment quantity, and dredged material management and beneficial use in the Delaware Estuary  Develop recommendations for the development of new

programs, procedures, d and d management practices i  Develop regionally-targeted regionally targeted goals goals, objectives and strategies

within a management framework to ensure consistent and fair consideration of Delaware Estuaryy RSM and beneficial use opportunities

Guiding Principles  Existing sediment management is unsustainable • Several S l authorities/jurisdictions th iti /j i di ti • RSM/BU framework lacking

 To create a “systems systems based approach” approach  To design solutions that fit within the context of a regional gy strategy  To improve sediment quality, quantity and sediment management while considering ecosystem interactions  To have various agencies, special interest groups, and the public participate in the process  Demonstrate RSM economic and environmental benefits

Goals  Quality: Manage sediment quality in the system to ensure it is capable of supporting a healthy ecosystem, meets water quality standards and supports beneficial use of the sediments. sediments y Manage g sediment as a resource such that areas that  Quantity: need sediment get it and those that don’t need sediment have outlets/methods to remove sediment or keep it out.  Dredged Material Management: Evaluate and enhance dredging and dredged material management such that navigational (commerce) needs are met while ensuring protection of other resource uses/benefits.  Beneficial Use/Restoration: Promote beneficial use of sediment for restoration, remediation and development such that the capacity for navigational dredging is supported and restoration goals are met.

Implementation Plan  Develop and disseminate the RSMP

g g Technical and Advisoryy Partners  Engage  Identify funding strategy for implementation activities  Craft metrics for assessing success/progress  Adopt the vision, objectives and recommendations  Select both regional and individual project RSM strategies for

development  Wetland creation demonstration project  CDF management and operations  Marsh restoration  Collaborate with RDT to facilitate RSM and BU opportunities
