Time to decommission your ash ponds?

In the last few years, our power generation industry has gone through major changes. Electricity needs to be produced at the lowest costs possible, but also in a way that meets or exceeds changing regulatory requirements. Many operations are currently or soon to be faced with the responsibility of decommissioning these ash ponds. Typically, there are two options for decommissioning; in place closure or removal of the ash from the ponds. Your dredging contractor will work with your Environmental Managers to establish a plan to best serve your particular ash pond needs, whether excavation of decommissioned ponds, or hydraulic dredging to remove ash. Your contractor should also have the capacity to dewater these materials by means of mechanical separation or use of geotextile tubes and polymers.

Whatever option you choose, C&M Dredging will gladly team with your operators to assist in proper decommissioning.

Featured Project

Hurricane Damage Restoration

Florida Keys

Highlights:

  • Remote Island Location 3 miles from mainland in FL Keys
  • Hydraulic Dredging to Geotextile tubes
  • Automated Polymer Injection System for Material Dewatering and Clean Effluent Requirements
  • Dewatering site constructed on sectional barge at island location
  • Dredging, Dewatering, Hauling and Disposal all simultaneously
  • Geotextile tubes transported by barge back to mainland daily for offloading into trucks
  • Sensitive Marine Benthic Resource avoidance and protection integral part of project requirements

Background:

C&M Dredging performed an environmental restoration dredging project to reverse impacts caused by hurricane damage to an island resort in the Florida Keys. A canal system and basin system that was in place for barges and vessels that serviced the island resort daily had been filled in by hurricane-force winds and tidal surge.

The difficulty was that the project site was 3 miles from the mainland, on an island.
