SUPPLEMENTARY INFORMATION: The BLM will serve as the lead agency and 
the USFS as the co-lead agency. The Idaho Department of Environmental 
Quality is a cooperating agency. The mining and reclamation plans have 
been developed and submitted for agency review of proposed open pit 
mining operations at the Rasmussen Valley Phosphate Federal Mineral 
Lease I-05975, in Caribou County, Idaho, by Nu-West Industries, Inc., 
doing business as Agrium Conda Phosphate Operations (Agrium). The 
Rasmussen Valley Phosphate Lease Area is located about 18 miles 
northeast of Soda Springs, Idaho.
    The proposed new mining operations at the Rasmussen Valley 
Phosphate Lease area lie on lands where the surface estate is 
administered by the BLM, the USFS, the Idaho Department of Fish and 
Game, and private owners. The Federal mineral estate is administered by 
the BLM. The portion where the surface estate is administered by the 
USFS lies within the Soda Springs Ranger District of the Caribou-
Targhee National Forest. The lease was originally issued in 1955. 
Subsequent lease transactions resulted in the transfer of the lease to 
Agrium in 2004. These leases grant the lessee, Agrium in this case, 
exclusive rights to mine and otherwise dispose of the federally owned 
phosphate deposit at the site. Through development of this EIS, the BLM 
and the USFS will analyze environmental impacts of the proposed mining 
operations and reasonable alternatives to the proposed action. 
Appropriate mitigation measures will also be formulated.
    Agency Decisions: The BLM Idaho State Director or delegated 
official will make a decision regarding approval of the proposed mine 
and reclamation plan, a proposed lease modification or grant of a 
fringe acreage lease (enlargement of leased areas), and appropriate 
land use authorizations on leased lands. Decisions will be based on the 
EIS and any recommendations the USFS may have regarding surface 
management of leased National Forest System lands. The USFS Caribou-
Targhee National Forest Supervisor makes:
    (1) Recommendations to the BLM concerning surface management and 
mitigation on leased lands within the Caribou-Targhee National Forest; 
and
    (2) Decisions on mine related activities that occur off-lease 
within the Caribou-Targhee National Forest. Special use authorizations 
from the USFS would be necessary for any support structures and 
facilities for the mine located off-lease within the Caribou-Targhee 
National Forest.
    The Army Corps of Engineers may also make decisions related to 
permits under Section 404 of the Clean Water Act.
    Background: Agrium has operated the existing North Rasmussen Ridge 
and Dry Valley Mines since 2003. Agrium has indicated that they will 
eventually complete mining of these currently permitted reserves, 
requiring the proposed mining of the Rasmussen Valley phosphate lease 
if mining is to continue in the immediate area. Because of the 
significant construction time associated with the infrastructure needed 
for the proposed mine (new haul road and mine infrastructure), this 
proposal is being analyzed in advance of depleting the currently 
permitted ore reserves at Agrium's North Rasmussen Ridge and Dry Valley 
Mines. The proposed Rasmussen Valley Mine project would include an open 
pit phosphate mine and associated features including growth media 
stockpiles, temporary and permanent external overburden storage areas, 
storm water retention ponds and mine pit backfill areas, a haul road, 
an equipment staging area, and re-routing of an existing county road 
and power line.
    The lease currently contains 511.4 acres of which approximately 
311.4 acres are on National Forest System Lands, 40 acres are on BLM 
public lands, and 160 acres are on lands managed by the Idaho 
Department of Fish and Game (IDFG). The lessee has proposed a lease 
modification (enlargement) of the Federal Phosphate Lease I-05975 in 
three areas totaling 170 acres to allow optimum recovery of existing 
ore currently contiguous to Lease I-05975. This proposed modification 
will be analyzed in the EIS. Approximately 420.4 acres are proposed for 
disturbance both on-lease and off-lease by the mining project, of which 
198.5 acres would be on National Forest System Lands, 28.7 acres on BLM 
public lands, 134.9 acres on the IDFG Blackfoot Wildlife Management 
Area, 0.4 acres on Idaho Department of Lands, and 57.9 acres on private 
land.
    Of the total proposed 420.4 acres of disturbance, approximately 
310.3 acres are on-lease for the mine pit, backfill areas, temporary 
and permanent external overburden disposal areas, an

[[Page 11261]]

equipment staging area and haul roads, and approximately 110.1 acres of 
disturbance are off-lease for haul roads, a county road re-route, 
growth media stockpiles and storm water retention ponds.
    Of the 110.1 total acres of off-lease disturbance, 31.3 acres are 
proposed to be disturbed on private land, and 13.6 acres are proposed 
to be disturbed on National Forest System Lands within the 170-acre 
proposed lease modification. Off-lease disturbance on National Forest 
System Lands of approximately 30.8 acres for the haul road, storm water 
retention ponds, and growth media stockpiles is proposed to be 
permitted by a 71-acre Special Use Permit (SUP) rather than a lease 
modification. Off-lease disturbance of approximately 7.4 acres is 
proposed by Agrium on the Idaho Fish and Game's Blackfoot Wildlife 
Management Area, primarily for storm water retention ponds and the 
county road re-alignment. Approximately 26.6 acres of disturbance off-
lease on private land, but not within the lease modification, is 
proposed for the haul road, storm water retention ponds, and growth 
media stockpiles. Approximately 0.4 acres of proposed off-lease 
disturbance for the haul road is on land managed by the Idaho 
Department of Lands. Mining is proposed to begin at the southern end of 
the Rasmussen Valley Mine deposit, continuing northwest through the 
deposit to the extent of the lease. Initially, overburden from the pit 
would be placed in an external overburden storage area located on-lease 
directly to the west of the pit. As mining progresses northwest, 
overburden would be placed either back in the mined-out portion of the 
pit, or in additional external overburden storage areas located on-
lease to the west of the pit.
    Agrium has proposed management practices in its mine and 
reclamation plan to reduce environmental impacts. Reclamation would be 
conducted concurrently with mining. Agrium's plan emphasizes the 
backfill of mine pits and limiting the amount of overburden placed in 
permanent external storage areas. To reduce the potential for 
contaminant release to water or uptake into reclamation vegetation, 
Agrium is proposing to limit the amount of time that seleniferous 
overburden is exposed to the elements, to return all seleniferous 
overburden material to the mine pits, and to cap overburden with low-
seleniferous material consisting of approximately 3 feet of cherty 
material, overlain by 2 feet of growth media.
    Agrium has proposed to build associated new facilities including an 
ore stockpile and groundwater supply well(s). To assist personnel needs 
and mobile equipment operation, a small support staging facility would 
be constructed at the active mining site immediately west of the pit. 
This facility provides electrical power, fuel and grease storage within 
secondary containment, communication, safety structures, and a 
temporary shift change building.
    Off-lease facilities would include haul roads and storm water 
control features, and growth media stockpiles. Trucks would be used to 
transport ore to the Wooley Valley rail head and overburden to a 
permanent disposal area.
    Potential impacts to surface resources and water quality include 
erosion, an increase in stream sediment load, and contamination from 
dissolved metals and selenium. Agrium has proposed to implement 
practices designed to reduce, eliminate, or mitigate these impacts. 
Suitable growth media would be salvaged from disturbed areas for use in 
reclamation. Mine reclamation would include removal of facilities and 
equipment, backfilling pits as mining progresses, grading slopes, 
capping overburden disposal areas and pit backfill, restoring 
drainages, spreading growth media, stabilizing surfaces, revegetation, 
and testing and treatment for any remaining contaminants. Environmental 
monitoring will be performed to ensure impacts do not exceed those 
authorized.
    Issues initially identified for the proposed mining of the 
Rasmussen Valley phosphate lease include potential effects on 
groundwater and surface water quantity and quality; vegetation, soil 
and mineral resources; air quality; wildlife and their habitats 
(including fisheries); livestock grazing; wetlands and riparian 
habitat; recreation; and socio-economics such as employment and the 
continued operation of a fertilizer plant and support businesses; 
Native American rights, treaties, and land uses; visual resources; and 
cumulative effects.
    The EIS will analyze the Proposed Action and the No Action 
Alternative. Other alternatives may be considered that could provide 
mitigation of potential impacts.
    The tentative EIS project schedule is as follows:
    <bullet> Begin public scoping period and meetings: Winter 2011.
    <bullet> Estimated date for draft EIS and associated comment 
period: Spring 2013.
    <bullet> Final EIS publication: Winter 2014.
    <bullet> Record of Decision: Winter 2014.

At least three ``open-house'' style public scoping meetings will be 
held which will include displays explaining the project and providing a 
forum for commenting on the project.
    Meetings are planned to be held in Pocatello, Fort Hall, and Soda 
Springs, Idaho. The dates, times, and locations of the public scoping 
meetings will be announced in mailings and public notices issued by the 
BLM (see DATES above).
