Coast Guard Establishes Temporary Safety Zones for Blasting and Dredging Operations on Columbia River

The US Coast Guard is setting up two temporary safety zones on the Columbia River to protect the maritime public from potential hazards during blasting and dredging operations near St. Helens, Oregon, and the movement of explosives from Portland, Oregon to the work site, with one zone fixed around the blast area and the other zone moving around the barge KRS 200-6 carrying explosives.
