Conference paper


On March 10, 1983, President Ronald Reagan signed the Exclusive Economic Zone Proclamation, giving the United States sovereign rights to all resources within 200 nautical miles of its shorelines. Later that month, on March 28, the Minerals Management Service issued in the Federal Register a “Scoping Notice to Prepare an Environmental Impact Statement” for a proposed lease sale for polymetallic sulfides on the Gorda Ridge. Polymetallic sulfide deposits at other locations contain important concentrations of metals including copper, zinc, lead, silver, and gold. A Draft Environmental Impact Statement (DEIS) for the 40-millionacre lease sale was released in December 1983 (Zippin, 1983). The lease area is shown in Figure 22.1.
