Haddam Neck Decommissioning

Location: East Hampton, CT

Date: 2005

In this industrial project, Cashman dredged and improved the Connecticut River Channel to a minimum depth of 5.6 feet to gain access to the power plant’s discharge canal. River channeling material was then loaded onto deck barges and processed for disposal as non-regulatated dredge spoil containing radioactive material. Discharge material was processed by screening, then dewatering with a pug mill and adding a small percentage of cement on a batch basis to meet saturated surface dry conditions of no greter than 1 percent.
