Masonville DMCF Background • Masonville Dredged Material Containment Facility (DMCF) Components: Maryland Port Administration (MPA) placement facility for
dredged material from Baltimore Harbor DMCF footprint is 141 ac, including 130 ac of open water • 16 mcy capacity • ~20 year site life
• Mitigation Requirements: Offset fill of 130 ac of open
water Offset loss of 1 ac of vegetated wetland Offset 10 ac of impacts to Chesapeake Bay Critical Area
3
Compensatory Mitigation Package Non-tidal and tidal wetlands creation and enhancement Reef and fish habitat improvement Eel passage installation Shad and herring restoration Trash interceptor installation Stream restoration Uplands clean-up and remediation • Terrestrial habitat enhancement and diversification • Conservation easement

Community Enhancements • Coordinated directly with citizen groups and non-profit entities
• Project Components
Environmental Education Center Education and Research Allocation ADA Water Accessibility (fishing pier and docking pier) Walking Trails Outdoor Education Facilities

Upland Clean-up • Uplands Contamination Legacy Dumping – telephone poles, railroad ties, tires,
concrete and rubble Historic Fast Land – created by placing municipal waste and other contaminated debris in open water
• Environmental Impacts Remnant Debris – required characterization and
removal/disposal Soil Impacts – metals (arsenic, lead, mercury, chromium), PAHs (benzo-a-pyrene) – required characterization and remedial action
7
Upland Debris Clean up • Debris Removal 6,280 tons telephone pole
and railroad ties 700 tons concrete debris 146 tons scrap metal 31 tons of tires 7,466 tons misc. debris
8
Upland Remediation • Remedial techniques include installing soil cap to eliminate contact with impacted surface soils: Site characterization and risk assessment to determine remedial action
(30 acres require capping) Design of cap: • • • •
Typical two foot clean soil cap Tree preservations zones Shoreline stabilization Non-tidal wetlands creation
Proposed Areas of Remedial Action
