Why Waterfront Sites Are Different
Multi-Agency Jurisdiction
Sediment and MGP work intersects NJDEP / NYSDEC, USACE, NYCDEP, and often FEMA and state historic preservation offices. Sequencing permits wrong adds a season to schedule.
Legacy NAPL & Coal Tar
MGP and legacy waterfront sites carry residual NAPL, coal tar, and PAH impacts that behave differently than dissolved-phase contaminants. Remedial design has to reflect that.
Long-Term Performance
Engineered caps and cover systems live for decades. Cap design, monitoring, and O&M planning must be built for hydrodynamic, settlement, and climate-adaptation realities.
Sediment & Waterfront Capabilities
MGP remediation, sediment investigation and cap design, and engineered cover systems — delivered under one LSRP-led team.
MGP & Legacy Waterfront Site Remediation
Utility owners, redevelopers, and public agencies inheriting former MGP or legacy waterfront industrial sites requiring defensible closure pathways.
Full remedial delivery for former Manufactured Gas Plant (MGP) sites and legacy waterfront properties. Envicon personnel have supported the Harrison MGP / PATH Substation IRM and comparable programs, coordinating with NJDEP, NYSDEC, and utility owners on interim remedial measures and long-term closure.
What's Included
- Remedial investigation & feasibility study
- Interim Remedial Measure (IRM) design
- NAPL and coal tar characterization
- Contractor procurement & construction oversight
- NJDEP / NYSDEC / LSRP correspondence

Sediment Investigation & Cap Design
Utilities, port authorities, and industrial owners managing contaminated sediments in tidal waterways, harbors, or industrial canals.
Sediment investigation, bench-scale testing, and engineered cap design for contaminated waterways and marine sites. Track record includes the BICC Cables DCU Area 2B sediment remediation. Designs coordinate with USACE, NJDEP, NYSDEC, and NYCDEP dredging and disposal permitting.
