General Placement Options Open water placement (unconfined)
Open water placement (unconfined) Confined disposal Confined
disposal Upland Fast land creation Beneficial use Beneficial use
Wetland creation Beach nourishment Island/shoreline restoration
Innovative reuse Innovative reuse Mine reclamation Aggregate/bricks
Landfill placement Landfill placement 2
Volume Existing capacity or new site Existing capacity or new
site Existing placement capacity in the region Duration of
availability of existing sites with capacity Large volume projects
Large volume projects May overwhelm capacity at existing site May
have more volume than can be reasonably placed Beneficial use
Beneficial use Innovative reuse Innovative reuse Use of multiple
sites = extra handling Small volume projects Small volume projects
High costs per unit for new sites May not have sufficient volume
for a beneficial use or innovative reuse project 4
Slide 5
Physical Parameters Driver for beneficial use and innovative
reuse projects Driver for beneficial use and innovative reuse
projects Specific grain-size often required Specific grain-size
often required Beach nourishment = sand Wetland creation = minimum
amount of coarse grained material Some characteristics driven by
site goals Some characteristics driven by site goals e.g., cannot
use stiff clays for marsh restoration 5
Slide 6
Sediment Quality Concentrations of chemical constituents
Concentrations of chemical constituents Material with high levels
of contaminants may require: Material with high levels of
contaminants may require: Confined disposal Specific classes of
landfill or hazardous waste sites Treatment or stabilization
Screening criteria Screening criteria Open water testing
requirements Beneficial use screening Site-specific testing for
existing placement sites TCLP testing for landfills Salinity
Salinity Estuarine/marine sediments precluded from some options

aquatic life Section 103 Marine Protection Resource and Sanctuaries
Act Authorizations Authorizations Existing facilities / placement
areas / ODMDS State/local restrictions Beneficial use Handling
Handling No dewatering costs Does not required double handling
Costs Costs No tipping or placement fees Transportation/offloading
costs only Monitoring of placement Extensive testing required Other

Confined Disposal Sediment Quality Sediment Quality Upland
Testing Manual Testing can vary by location Authorizations
Authorizations May be restrictions based on type of material placed
Characteristics of material Characteristics of material Source of
material Source of material Existing - generally no permits or
approvals required New long lead time to design and permit Handling
Handling Dewatering generally managed at site Generally no double
handling Costs Costs Tipping/placement fees required
Transportation/offloading costs Other Other No environmental
benefits Can accept a wide range of material 10
Slide 11
Beneficial Use Sediment Quality Sediment Quality Cannot use
contaminated material Physical characteristics are key
Authorizations Authorizations Existing projects already permitted
and authorized Permit modifications Permit modifications Some sites
may restrict geographic sources (e.g. Corps restoration sites) Some
sites may restrict geographic sources (e.g. Corps restoration
sites) New projects need permits/approvals Handling Handling Varies
by site direct placement or multiple handling Dewatering may be
required Costs Costs Placement fee for existing sites High costs
for new projects design/permitting/monitoring Other Other
Environmental benefits Positive public image Opportunities for
partnering with local and national groups 11
Slide 12
Innovative Reuse Sediment Quality Sediment Quality Would
require testing/characterization of material Potential for pilot
testing Varies by proposed use Authorizations Authorizations
Unclear regulatory environment for some uses Handling Handling
Dewatering generally required Extra handling Treatment Cost New
infrastructure required Processing costs Other Other Infrastructure
availability Some not feasible for a single project Pilot vs.
large-scale processing 12 Source: MPA
Slide 13
Landfill Sediment Quality Sediment Quality Hazardous vs.
non-hazardous (TCLP) Paint filter test Authorizations
Authorizations Some facilities will not accept dredged material
Handling Handling Multiple handling barge, dewatering, truck,
placement Potentially time consuming Cost Cost High placement fee
per truckload or ton Other Other Capacity restrictions Traffic
concerns, need for sealed bed trucks, air emissions 13

Evaluation Develop a laundry list of all potential sites in an
area without regard to project criteria Develop a laundry list of
all potential sites in an area without regard to project criteria
Networking ask regulators, industry, placement site operators for
suggestions Networking ask regulators, industry, placement site
operators for suggestions Screen full list of sites against
criteria Screen full list of sites against criteria Rank viable
placement sites Rank viable placement sites Develop a short-list of
placement sites for detailed evaluation Develop a short-list of
