Dredging activities included mechanical and suction dredging of approximately 28,000 cy of MGP-impacted material from approximately 7.6 acres of the Nearshore and Offshore Areas of the site.  The Offshore Area is located within the federal navigation channel, and the Nearshore Area includes multiple structures such as docks, piers, and an active marine railway.

“It saves time, so therefore, it saves money,” agrees Blake Nelson, MnDOT technologies engineer. “It just goes down so much faster than any other means or method. You can cover a lot of area with these fabrics in a hurry.”

To facilitate dredging, the northern and southern hauling piers associated with the active marine railway and the decking of the Maritime Gloucester main pier were removed.  Prior to dredging in the Nearshore Area, debris including lines, cables, piles, and portions of an abandoned marine railway was removed and transported offsite for disposal.

The only other materials used in the installation are standard nursery crates and geotextile bags containing soil required to support the greenery’s growth.

Riverside and Pickering Marine Contractors, using a barge-based Komatsu PC1250 with environmental dredge bucket outfitted with a HYPACKTM bucket positioning system, conducted the majority of the mechanical dredging in the Offshore Area.  Charter Contracting self-performed the mechanical dredging in the Nearshore Area using a combination of barge-based equipment (Komatsu PC1250, PC600, and PC300).  Dredging was conducted within turbidity curtains (either stand-alone curtains or a mobile resuspension system) to minimize impacts to surface water outside the work area.

The fibre’s roots here go back more than 2,000 years. Mentioned in ancient Sanskrit texts, it was spun on peasants’ hand looms into twine and simple clothing. In the 19th century, British colonialists developed the rough, sturdy textile as a packaging cloth for bulk foodstuffs. They built mills on the banks of the Hooghly to churn out coarse sacks used to carry coffee, cocoa and grains around the world.

But Steinauer was concerned a gap lot between sections of geotube could be too long, and possibly weaken the structural integrity of the bluff by increasing erosion.

If, as expected, the court approves an agreement between the Environmental Protection Agency and environmental groups to revise the coal ash rule, companies like Dominion will be required to monitor groundwater around any closed ponds for 30 years— and to clean up any coal ash contaminants that might be detected there.
