ENVIRONMENTAL PROTECTION AGENCY
[ER-FRL-5414-5]
Intent To Prepare a Supplemental Environmental Impact Statement
(SEIS) for the Alaska-Juneau (AJ) Mine Project, Juneau, AK
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of intent to prepare an SEIS.
-----------------------------------------------------------------------
SUMMARY: In accordance with Section 511(c)(1) of the Clean Water Act
(CWA) and Section 102(2)(c) of the National Environmental Policy Act
(NEPA) EPA has identified a need to prepare an SEIS and publishes this
Notice of Intent in accordance with 40 CFR 1501.7.
FOR FURTHER INFORMATION OR TO SEND SCOPING COMMENTS: William Riley,
Office of Water Mining Coordinator OW-135, EPA, 1200 Sixth Avenue,
Seattle, WA 98101, phone (206) 553-1412. Local contact is Steve Torok,
EPA's Juneau office, phone (907) 586-7619.
SUPPLEMENTARY INFORMATION: The proposed AJ Mine Project is subject to
EPA authorization through CWA Section 402, including the National
Pollutant Discharge Elimination System (NPDES) permit program. The
project is a new source (40 CFR 122.2 and 122.29), and under CWA
Section 511(c)(1) is subject to NEPA prior to the NPDES permit decision
(40 CFR Part 6, Subpart F). The AJ Mine is an underground gold mine,
located south of Juneau, Alaska, which closed in 1944. In 1988, Echo
Bay, Alaska (Echo Bay) filed necessary permit applications to reopen
the mine and an EIS was completed by the Bureau of Land Management in
1992. During the permitting phase, EPA completed a technical assistance
report which concluded there was a high potential for significant
degradation of the waters of the United States. Echo Bay proposed
modifications to address concerns raised and filed new permit
applications. EPA also commenced a rule-making that would allow
consideration of submarine tailings disposal. New field studies to
characterize marine and other resources are ongoing.
Project Description--The reopened AJ Mine would produce 15,000 tons
per day of ore, and 80 million tons during the 13-year project life.
Gold recovery would be by means of gravity separation and froth
flotation processes in an underground mill. No cyanide would be used.
Surface facilities would be located at the Rock Dump area south of
Juneau. The tailings would be pumped through a pipeline in Gastineau
Channel for discharge at depth in Stephens Passage. Power would be
supplied by diesel-gas turbine generators. Staffing is estimated at 400
personnel.
Project alternatives currently considered include: (1) Douglas
Island Dry Tailings--the tailings would be piped across Gastineau
Channel, dewatered and conveyed to a dry tailings disposal area on
Douglas Island, (2) Sheep Creek Subaqueous Tailings--similar to the
proposed action in the 1992 FEIS except the impoundment would hold less
tailings, no cyanide would be used, and the flows of Sheep Creek would
be partially diverted around the impoundment, (3) Powerline Gulch
Subaqueous Tailings--similar to an option in the 1992 FEIS, except the
impoundment would hold less tailings, no cyanide would be used, and
surface runoff would be diverted around the impoundment, (4) Mine
Backfill and Douglas Island Dry Tailings--combining backfilling of
cemented tailings with surface disposal at a reduced dry tailings site
on Douglas Island, (5) Submarine Tailings Disposal Upland Pipeline--
similar to the proposal, except the tailings pipeline would follow an
upland route along Gastineau Channel and to Stephens Passage for
discharge.
SCOPING MEETING DATE AND COMMENT DEADLINE: On April 17, 1996, EPA will
host an SEIS scoping open house at Centennial Hall in Juneau from 3:00
to 9:00 p.m. Scoping comments from the public will be welcomed that
day, or they may be submitted to EPA in writing. The scoping period
comment deadline is April 30, 1996.
ESTIMATED DATE OF DRAFT SEIS RELEASE: September, 1996.
Dated: March 20, 1996.
Richard E. Sanderson,
Director, Office of Federal Activities.
