NJDEP Course of Action

  • Better Control of Access to the Landfill
  • Better Control of Public Works Activity
  • Remove all Surface Debris from the Landfill
  • Stabilize the Eroded Bank and Eliminate

Discharge of Leachate from the Landfill

From April 2007 letter from Michael Hansen (NJDEP) www.ocean-coastal.com

Stabilize the Erosion

  • SIC Hired ASG to Investigate the Erosion
  • f the Western Bank of the Landfill

– ASG Assessed Erosion (loss of ~2.6 acres) – Developed a Temporary and Long Term Erosion Solution

  • SIC Proceeding with Temporary Erosion

Control

  • Long Term Solution Must be Implemented

Landfill Closure

Purpose of Proper Closure

– Physical Barrier – Pollution Control – Necessary for End Use

  • Closure Regulations (NJDEP)

– Erosion Control – Final Soil Cover Material is Needed for Closure ~75,000 cy

www.ocean-coastal.com

Material Options

  • Material Quality is Regulated by NJDEP
  • Material Needs to be Suitable for Plant Growth
  • Typical Material Options
  • Alternative Material Options

Partnership with NJDOT

Material is Needed for Landfill Closure

Beneficially Re-Use Dredged Material for Landfill Closure!!! WIN - WIN NJDOT Seeks to Beneficially Re-Use Dredged Material

www.ocean-coastal.com

State Dredging

  • Dredging is Needed for Navigation Channels
  • State is Responsible for Providing Capacity

for NJICWW Dredging

  • Dredged Material Placement Options

– Confined Disposal Facility (CDF) – Beneficial Re-Use
