3 PORT OF NEW YORK AND NEW JERSEY 15 Million People Largest Port on East Coast Largest Petroleum Port Naturally Shallow, 250 miles of engineered waterways 4-7 mcy/year dredging Oldest Industrialized Watershed 2-4 mcy/year contaminated sediment

4 Statewide Dredging Delaware River 40 Foot Depth Primarily Commercial 5 mcy/year Intercoastal Dredging 6-12 foot depth Recreation and Commercial Fishing 1 mcy/yr Berths, terminals and marinas Upland Management

5 What is dredging? Dredging is the act of construction or maintenance of an underwater highway Dredged material is the sediment removed during these actions =

6 Dredging Methods in New Jersey

7 What is Dredged Material? Sand, silt or clay particles Not soil, but may be amended and used as soil Periodic removal required Storm events Landside runoff May contain contaminants

8 Confined Upland Disposal

9 Aquatic Disposal

10 1993: Mudlock Mudlock begins

11 So why all the fuss? Sediment and soil particles adsorb and concentrate pollutants Sediments can be a historical record of pollution Increased public awareness and concern about industrial contaminants Sediments are the main source of food for the aquatic community NIMBY: Marine sediments can be unsightly and compete for space

12 Sediment Management Decision Making Increasing Concentration Increasing Hazard Preindustrial Zone Judgement Zone Hazardous Waste Zone SQV: Background Assessment Tool Depends on Situation SQV: RCRA Decreasing Management Options Increasing Cost of Management

13 What Happens to Our Dredged Material? Manufactured Soil Aggregate Intermediate Landfill Cover Ocean Disposal Beach Nourishment 1 Habitat Restoration/Creation Upland Fill Highway Construction Manufactured Soil Ocean Disposal Landfill Final Cap Landfill Liner Upland Fill Nearshore Fill Brownfield Cover Habitat Restoration/Creation Highway Construction Upland Fill Brownfield Cover Habitat Restoration/Creation Nearshore Fill Manufactured Soil Highway Construction Sand [>.0625 mm] Clean 3 Clay [<.0039 mm] Contaminated 2 Silt [>.0039 mm] [<.0625 mm] Intermediate Landfill Cover Confined Aquatic Disposal Confined Upland Disposal Upland Fill Nearshore Fill (with Capping) 1 75% Sand; grainsize distribution must be equivalent to existing conditions 2 Uses assume no decontamination 3 Uses assume clean or decontaminated Confined Aquatic Disposal Confined Upland Disposal Nearshore Fill (with Capping) Landfill Cap (with Clean Cover) Brownfield Cap (with Clean Cover) Mine Reclamation Confined Aquatic Disposal Confined Upland Disposal Nearshore Fill (with Capping) Landfill Intermediate Cover Mine Reclamation Brownfield Cap (with Clean Cover) Decontamination and Disposal

14 The Solution: Beneficially use as much as possible Foster development of alternative technologies that are efficient and effective 1996 Joint Dredging Plan ($130 mil) 1996 Dredging Bond Act ($205 mil) Develop new regulatory programs Plan, coordinate and communicate

15 Sediment Stabilization

16 Landfill Capping

17 Brownfield Reclamation

18 Abandoned Mine Reclamation

19 Beneficial Use of CDF Material

21 Jersey Gardens Mall 800,000 cyd

22 Bayonne Landfill 1,000,000 cyd

23 Bark Camp Mine Reclamation 400,000 cyd

24 BioGenesis Sediment Washing System

25 ENDESCO/Clean Harbors Rotary Kiln Thermal Destruction

26 Riverwinds Golf Course 160,000 cyd

28 New Jersey's Dredged Material Management Plan W ill the dredging occur in navigation channels or berths? Yes Evaluate existing data Data indicates little or no contamination Beneficial Use or upland disposal in CDF No Evaluate need and risk vs. benefit Historical Contamination? Insufficient data or unacceptable contamination No Ocean Disposal Planned? Yes Sampling Plan and Testing Still needed? No Yes Yes Sampling Plan & Testing No No HARS criteria met? 5 Yes HARS Placement Alternative Strategy 1. Residential Direct Contact Soil Cleanup Criteria. NJDEP as amended. 2. Acceptable Use Determination for placement/use of dredged material. Unrestricted Upland Beneficial Use or CDF Placement Yes Meet Applicable Water Quality Standards? Yes Meet RDCSCC? 1 3. Sediment deconatamination facilities will have specific criteria for acceptability of material based on treatability and final use. Restricted Upland Beneficial Use Yes No Capacity? No Yes No Meet site specific criteria? (AUD) 2 No 4. RCRA guidelines are used to determine if a nonwaste material is contaminated to a hazardous level. Material that exceeds RCRA criteria must be handled as a hazardous waste. 5. HARS criteria are based on ocean disposal criteria as amended by USEPA--Region 2 and USACE--NY District for determination of suitability as capping material at the Historic Area Remediation Site (HARS). Sediment Decontamintation and Beneficial Use Yes Capacity? Yes Meet Decon. Facility Criteria? (AUD) 3 No Below RCRA Hazardous W aste Criteria? 4 No Special Management No Yes Confined Disposal Yes Site Specific Terrestrial Concerns Addressed? Yes Site Specific Groundwater Concerns Addressed? No No Special Management Special Management

29 Regional Dredged Materials Management Plan (DMMP) Reduce Need to Dredge Reduce Contamination Beneficially use as much as possible Dispose of only what cannot be used
