Designation of Critical Habitat for the Hine's Emerald Dragonfly: Revised proposed rule; reopening of comment period and notice of availability of draft economic analysis, and amended Required Determinations.

We, the U.S. Fish and Wildlife Service (Service), announce the reopening of the public comment period and the availability of the draft economic analysis for the proposed designation of critical habitat for the endangered Hine's emerald dragonfly (Somatochlora hineana) under the Endangered Species Act of 1973, as amended (Act). We are also revising our proposed rule, published on July 26, 2006 (71 FR 42442), to include an additional proposed critical habitat unit in Door County, Wisconsin, and amending the Required Determinations for the proposal. The draft economic analysis forecasts that costs associated with conservation activities for the Hine's emerald dragonfly would range from $16.8 million to $46.7 million in undiscounted dollars over the next 20 years. In discounted terms, potential economic costs are estimated to be $13.3 to $34.5 million (using a 3 percent discount rate) and $10.5 to $25.2 million (using a 7 percent discount rate). In annualized terms, potential costs are expected to range from $0.8 to $2.3 million annually (annualized at 3 percent) and $0.9 to $2.4 million annually (annualized at 7 percent). We are reopening the public comment period to allow all interested parties an opportunity to comment simultaneously on the proposed rule, our revision to the proposed rule, the associated draft economic analysis, and the amended Required Determinations. Comments previously submitted need not be resubmitted as they will be incorporated into the public record and fully considered in preparation of the final rule.
