FORMER KINSTON MGP SITE Coffer Dam Kinston, NC November 2013 to May 2015 $6 M Zero OSHA Recordables Duke Energy (Owner) /Silar Services (Engineer) NorthStar constructed a 300’ by 100’ by 100’ coffer dam within the Neuse River to facilitate the removal of ~2,400 CY of MGP impacted sediments. NorthStar worked off modular barges using an environmental clamshell bucket to dredge the sediments. The sediments were dewatered on top of the barge. Sediments were then excavated from the transport barge and loaded onto articulating dump trucks for the nearly ½ mile trip to the sediment mixing area. The upland MGP impacted soils and sediments were then blended with cement and slag reagent add mix and stabilized to an average depth of 18-22 feet BGS at >50 psi unconfined compressive strength and 1×10 to the minus 7 permeability was achieved through the stabilization process. Once all of the 62,000 CY of soils/sediments achieved the desired performance criteria the site was capped.

WEST BANK & VICINITY (WBV) 72 – LEVEE REPAIRS Levee New Orleans, LA November 2009 – February 2011 $32 M Zero OSHA Recordables Following the extensive damage of Hurricane Katrina in August 2005, legislation authorized and funded the reconstruction and improvement of the levee system in the New Orleans region. WBV 72 is part of the West Bank and Vicinity Hurricane Storm Damage and Risk Reduction System (HSDRRS). WBV 72 is a clay levee located in St. Charles Parish and serves the system as a Lake Cataouatche Western Tie In Levee (or East-West Levee). The WBV 72 construction was designed to add to the existing levee, but not directly on top. As in many of the other ongoing improvement projects, the design called for off-setting the new alignment behind the existing levee and building it taller and farther back.
