B. Departmental Activities to Respond to the Act
On December 5, 1988, the Director of the
National Park Service (NPS) asked the Congress for a delay in the submission
date for the report until the summer of 1990 and promised to provide an interim
report on the progress of the investigations at Crater Lake. In the Fall of
1989, the NPS submitted the interim report to the Senate Committee on Energy and
Natural Resources and the House Committee on Interior and Insular Affairs.
The House Interior Subcommittee on Mining and Natural Resources held oversight
hearings on September 28, 1989. The hearings addressed the implementation of the
Federal Onshore Oil and Gas Leasing Reform Act of 1987 and the Geothermal Steam
Act Amendments of 1988. The Subcommittee Chair asked the Department of the
Interior to provide updates on the studies conducted at the Corwin Springs area
north of Yellowstone National Park and those at Crater Lake National Park.
Interior testified at the hearings that the final report would be completed for
submission to the Congress by late summer of 1991. This report represents the
findings of the completed research on the hydrothermal features at Crater Lake
National Park and fulfills the requirements of Section 7 of the Act. This report
does not address the question of a connection between the hydrothermal features
in Crater Lake and areas of geothermal exploration on U.S. Forest Service lands
near the Park. (The history of geothermal leasing near the park is included as
Appendix D.)
