Section 01 57 20.00 10 Attachment Page 1

Specifications for Contractors Concerning Prevention of Spread of Dreissena from Infested to Uninfested Waterways

Background

Zebra mussels and quagga mussels (Dreissena polymorpha and D. bugensis) are black and white striped freshwater mussels that live attached to virtually any hard surface and clog power plants, industrial and drinking water intakes, foul boat hulls, and disrupt ecosystems. Their economic and ecological impacts are serious. Prevention of their spread when boats and other equipment are moved from a potentially infested to uninfested waterway is necessary.

The Contractor must certify that all equipment associated with the construction project that will be used within the reach of the Missouri River designated as the Missouri National Recreational River (MNRR) is free of zebra mussels (Dreissena polymorpha) or zebra mussel larvae prior to entering the MNRR. If any construction equipment has been in zebra mussel infested waters, which includes but not limited to of the Great Lakes as well as the Mississippi, the Arkansas, the Ohio, the Illinois, the Tennessee, the Susquehanna and the Hudson rivers, the following checks and possible subsequent decontaminations must be completed prior to equipment entering the MNRR.

Step 1. Inspection

All waterborne vessels will be pulled out of the Missouri River at or downriver of Sioux City, Nebraska/Iowa. At the location where the boats are pulled out, thoroughly inspect hulls, drive units, trim and trolling plates, props and prop guards, transducers, anchors, ropes, and chains, trailers and any other equipment that has been kept wet.

All bilge water, live wells, engine cooling water, and any other water associated with the equipment should be drained at least one quarter mile from the river and it must be ensured that discarded water does not flow into the river.

Aquatic vegetation clinging to equipment or vessel should be removed and discarded.

Any attached mussels must be scraped off and thrown in the trash. Likewise, bait and bait bucket water must be similarly discarded.

Should zebra mussels be found during this inspection, or if the vessel has been in contaminated waters, one of the following two methods must be taken to prevent their spread.

Step 2. Cleaning

Option 1. Hot Water Rinses

Hot Water Rinses may be used to decontaminate vessels and equipment. This acts to kill the mussels and remove them from equipment. A high-pressure, hot water (120°F) washer should be used. These rinses are required for hulls, drive units, props and guards, Am 0001

Section 01 57 20.00 10 Attachment Page 2 trim and trolling plates, anchor chains and ropes, bilge and live wells, trailers and engine cooling systems.

Option 2. Aerial Exposure

Equipment and vessels must left in the open, not in the shade, for at least 5 full days (120 hours). In addition, equipment and vessels must be completely dry for 2 full days (48 hours) prior to re-entering the Missouri River at the project site.

Step 3: Documentation

All inspection and cleanings must take place under the supervision of the contracting officer’s representative (COR). The COR must be given at least two business days notice prior to inspection. Written certification that equipment is free of zebra mussel contamination shall be presented to the COR prior to mobilizing the equipment into the MNRR. This is to include a list of checks performed, findings and decontamination activities.
