Endangered and Threatened Wildlife and Plants; Notice of 
Availability of Reports and Other Data Pertaining to the Listing of the 
Bruneau Hot Springsnail

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Notice of availability, opening of public comment period.

-----------------------------------------------------------------------

SUMMARY: The U.S. Fish and Wildlife Service (Service) gives notice that 
reports and other data pertaining to the listing of the Bruneau hot 
springsnail (Pyrgulopsis bruneauensis) are available to the public. 
Specifically, the Service is seeking public comment on a U.S. 
Geological Survey report and other reports and data received since the 
listing of the springsnail. In addition, the Service solicits any other 
information relevant to determining whether the springsnail should be 
listed as an endangered species. The Service opens the public comment 
period until November 13, 1995.

DATES: The comment period is open until November 13, 1995. Any comments 
and materials received by the closing date will be considered in the 
final determination.

ADDRESSES: Comments and materials concerning the reports and other 
information pertaining to the listing of the Bruneau hot springsnail 
should be submitted to the U.S. Fish and Wildlife Service, Snake River 
Basin Office, 4696 Overland Road, Room 576, Boise, Idaho 83705. Reports 
and other data cited in this notice, and public comments and other

SUPPLEMENTARY INFORMATION:

Background

    On January 25, 1993, the U.S. Fish and Wildlife Service (Service) 
published a final rule in the Federal Register determining the Bruneau 
hot springsnail (Pyrgulopsis bruneauensis) to be an endangered species 
(58 FR 5946). In its decision to the list the springsnail the Service 
relied, in part, on a provisional draft of a U.S. Geological Survey 
(USGS) report (Berenbrock 1992) analyzing the hydrology of the 
geothermal aquifer in the Bruneau Valley area. The USGS provided the 
Service with the draft report, but did not release it to the public and 
requested that the Service not release the report to the public, 
pending agency review and approval.
    On May 7, 1993, the Idaho Farm Bureau Federation, Owyhee County 
Farm Bureau, Idaho Cattleman's Association, and Owyhee County Board of 
Supervisors challenged the listing decision on several grounds in a 
lawsuit filed in United States District Court for the District of 
Idaho. The plaintiffs argued that the Service committed a number of 
procedural violations during the listing process, including not 
allowing the public to review the draft USGS report. On December 14, 
1993 the district court determined that the Service committed several 
procedural errors and set aside the final rule listing the springsnail 
as an endangered species.
    The district court decision was appealed to the United States Court 
of Appeals for the Ninth Circuit by two intervening conservation 
groups, the Idaho Conservation League and Committee for Idaho's High 
Desert. On June 29, 1995 the appellate court overturned the district 
court decision and reinstated the Bruneau hot springsnail to the 
endangered species list. However, the appellate court concluded that 
the Service should have made the draft USGS report (i.e., Berenbrock 
1992) available for public review, as the Service relied largely on 
this report to support the final listing rule. The appellate court 
directed the Service to provide an opportunity for public comment on 
the USGS report and other relevant information, and to reconsider its 
listing decision. This notice of availability complies with the court's 
direction.

Available Reports and Data

    In addition to the draft USGS report, which was finalized in August 
1993 (i.e., Berenbrock 1993), the Service has additional reports and 
information pertinent to the listing decision received since the 
original listing rule was published January 25, 1993. The following 
information contained in
