13 Sediment Processing Facility and other Sites Selection Process

14

15 Upland Sites Needed Sediment Processing Facility Includes water treatment plant, separated sand and filter cake staging, managing large debris, waste loadout and shipment; accommodations for operations management and staff; may also include space for staging clean aggregate materials for cap construction Staging Area Sites Strategically located along the river for storing clean aggregate materials (e.g., sand, armor stone, thin cap materials) that are used for cap construction; several may be used Support Sites Used to store spare parts for dredging, sand spreading or process equipment, slurry pipeline sections for maintaining the in-river transfer conduit to the Sediment Processing Facility; sites down to 1 acre will be considered River Access Locations Needed for entry/exit from the river

16 Selection Criteria Sediment Processing Facility Proximity to dredge and cap areas between RM 0 and RM 2.6 is advantageous Usable size - at least 20 acres is desirable Transportation options truck, rail Engineering criteria Waterfront access Docking/mooring infrastructure Rail accessibility and capability Road access and capability Utility services Subsurface conditions and subsurface features

17 Selection Criteria Sediment Processing Facility Environmental impact criteria Cultural resources Existing and historical land uses Habitats critical to ecological processes Regulatory and land use criteria Proximity to residential and sensitive facilities Zoning Land acquisition/leasing

18 Site Selection Study Area Locale 1 OU 2, extending from the Passaic River s Confluence with Newark Bay at River Mile (RM) 0 to RM 8.3 Subdivided into 3 segments based on proximity to areas of significant dredge material volume Segment 1: RM 0 to 2.6 Segment 2: RM 2.6 to 5.7 Segment 3: RM 5.7 to 8.3

19 Site Selection Study Area Locale 2 Newark Bay from the mouth of the Lower Passaic River southward and into Arthur Kill to its confluence with the Rahway River

20 Site Selection Study Area Locale 3 Newark Bay from the mouth of the Lower Passaic River northward into the Hackensack River up to the Interstate 95/New Jersey Turnpike bridge crossing (Lewandowski Bridge)

21 Vicinity and Site Selection Evaluation Study Area Preliminary Candidate Sites (Locales 1 & 3)

22 Vicinity and Site Selection Evaluation Study Area Preliminary Candidate Sites (Locale 2)

23 Vicinity and Site Selection Study Area Segment 3 Segment 2 Segment 1

24 Estimated In-Situ Dredge Volume by River Mile

25 Commercial and Municipal-Owned Sites Clean Earth North Jersey Facility Located within Segment 1 (RM 2.4), this existing hazardous and non-hazardous industrial waste facility could be used to either directly accept limited volumes of dredged material or to support a newly developed sediment processing facility. Clean Earth Koppers Facility Located along the Hackensack River, this existing facility specializes in the management of non-hazardous dredged sediment and could be used to either directly accept dredged material or be developed by utilizing the existing facility infrastructure (to the extent practical) and constructing a sediment processing facility on any potentially available undeveloped portions of the site. Passaic Valley Sewerage Commission (PVSC) Facility Commercial/Governmental property located within Segment 1 (RM 0.3) with sufficient space available to host a sediment processing facility. Potentially existing sewerage and water treatment operations could be modified or incorporated into sediment treatment facility operations. Municipal-Owned Sites Properties within Locales 1 and 3 will be considered for use as support sites; GSH is currently utilizing a property owned by the Town of Harrison at RM 5.4 as a river access point for pre-design investigation field operations.
