Purpose and Need for the Proposed Action

Itafos Conda LLC is proposing to exercise mining rights that the Unites States has previously granted in Federal phosphate leases that it currently holds or controls. The company has developed and submitted an MRP for the Husky 1 North Dry Ridge Phosphate Mine. The purpose is for the BLM and Forest Start Printed Page 83995Service to evaluate and respond to the plan submitted for the recovery of phosphate ore and to modify leases, in accordance with the Mineral Leasing Act of 1920 as amended. As the surface management agency, the Forest Service will provide the BLM with formal recommendations on the BLM's action to modify the lease (43 CFR 3503.20), evaluate and respond to the MRP, and issue Special Use Authorizations for the portion of operations that would occur on National Forest System (NFS) lands outside lease boundaries (36 CFR 251.50). Itafos Conda LLC has the exclusive right and privilege to recover phosphate from their leases, including the exploration, mining, and disposal of the phosphate or phosphate rock. The U.S Army Corps of Engineers (USACE) purpose as a cooperating agency in preparation of an Environmental Impact Statement, is to evaluate and consider the MRP relative to a permit decision under Section 404 of the Clean Water Act. The need for the Husky 1/North Dry Ridge Project is to develop the phosphate resource, using an economically viable method, in accordance with Federal laws and regulations governing Federal mineral leases, and to allow Itafos Conda LLC to exercise its right to develop the leases and ensure economically viable and continuous phosphate operations that are in compliance with established requirements. Ultimately, the project would supply phosphate ore to the plant in Soda Springs, ID.

Preliminary Proposed Action and Alternatives

The proposed action includes two open phosphate mining pits—the North Dry Ridge and Husky 1—in portions of the existing North Dry Ridge, Husky 1, and Maybe Canyon Mine leases, and proposed lease modifications. Mining would proceed in phases with overburden first placed in existing South Maybe Canyon pits, followed by backfilling the Husky 1 and North Dry Ridge pits as room is made available. A portion of the Husky 1 pit overburden would also be used to construct a permanent external overburden stockpile for use in reclamation and to buttress mine features such as the relocation of the upper portions of Maybe Creek.

Additional mine facilities include growth media stockpiles, temporary overburden storage areas, water management features, dust suppression and water supply wells, haul roads, equipment staging areas, fuel storage areas, train loading facility (tipple), ore stockpiles, and the shop and office area. The existing offices and shop facilities at the Dry Valley Mine would be used as the main base for Project operations. The Dry Valley yard area would be used for fuel storage tanks, an equipment parking/hot start line, and a laydown yard.

Ore would be transported via haul roads from the mine pit areas to an ore stockpile and tipple, then loaded onto railcars and transported by existing rail line to Soda Springs. The proposed action includes closing a portion of an existing NFS Road (#134) for the duration of mining and reclamation. It also proposes that the Blackfoot River Road be used as the primary means for the public to access Diamond Creek Valley and Dry Valley. The mine would encompass approximately 2,096 acres of Federal land, including existing Federal phosphate leases (1,504 acres), proposed lease enlargement modifications (479 acres), and Forest Service Special Use Authorizations (113 acres), and an additional 9 acres of private land. Mining operations would disturb approximately 1,145 acres of which approximately 1,122 acres, or 98 percent, would be reclaimed. The remaining 2 percent consists of some residual pit walls exposed in the partially backfilled pit area and haul roads that would be partially reclaimed to allow for continued access necessary for maintenance and monitoring activities.

To reduce environmental impacts, the MRP emphasizes the backfilling of mine pits and covering with earth, and in some locations compacted clay, to minimize the release of contaminants to ensure that water quality meets the Idaho Ground Water Quality Rule and other established requirements. Portions of Maybe Creek and Stewart Creek may be realigned to ensure the creeks do not encounter selenium materials or backfill and transport contaminants offsite. Suitable soil or other growth media would be salvaged from disturbed areas for use in reclamation. Concurrent mine reclamation would include backfilling pits as mining progresses, grading slopes, capping overburden disposal areas and backfilled pits, reestablishing drainages, spreading growth media, stabilizing surfaces, promoting revegetation, and testing and treatment for any remaining contaminants. Facilities and equipment would be removed at closure. Environmental monitoring would be performed to ensure impacts do not exceed those authorized. Mining would occur for approximately 15 years, followed by approximately one year of final reclamation.

A complete evaluation of the project consistency with the Caribou National Forest Revised Forest Plan may indicate the need for project-specific Forest Plan amendments. In addition to the No Action (not approving the MRP, lease modifications, or Special Use Authorizations) and the Proposed Action, possible alternatives may include: Changing the type or location of cap and cover materials or permanent drainage, modifying the mining area to avoid the Inventoried Roadless Area, eliminating the permanent overburden stockpiles, avoiding closure of the Stewart Canyon Road to recreation during mining, avoiding the lease modifications, avoiding the need for special use permits, or avoiding or modifying the realignment of Maybe and Stewart creeks. Other alternatives may be identified from scoping comments or through analysis.

Summary of Expected Impacts

The BLM expects mining and hauling operations to change groundwater and surface water quantity and quality within regulatory limits; remove and change the structure and composition of vegetation including species important to Native American tribes; disturb wetlands and riparian habitat; modify wildlife and fish habitat; temporarily reduce areas available for recreation (including hunting and camping) until reclamation is complete; change scenery; disturb soil; permanently remove mineral resources; create vehicle emissions and fugitive dust; extend economic activity such as employment and the continued operation of an elemental phosphorous plant; support businesses and generate tax revenue; and reduce livestock grazing.

Idaho Department of Environmental Quality anticipates a Point of Compliance in December 2021 and Idaho Department of Land anticipates a reclamation plan approval in 2022.

Public Scoping Process

This notice of intent initiates the scoping process, which guides the development of the Environmental Impact Statement. Scoping meetings will be virtual. An announcement about when and how to access the virtual meetings online will be posted on the BLM's project website.

The purpose of public scoping is to identify relevant issues that will influence the scope of the environmental analysis, including alternatives, and guide the process for developing the environmental impact statement. The BLM and Forest Service will use and coordinate the NEPA public scoping to help fulfill the public involvement requirements under the National Historic Preservation Act (54 U.S.C. 306108) as provided in 36 CFR 800.2(d)(3). The information about historic and cultural resources within the area potentially affected by the proposed action will assist the BLM and Forest Service in identifying and evaluating impacts to such resources.

The BLM and Forest Service will conduct government-to-government consultation with Indian tribes in accordance with Executive Order 13175 and other policies. Agencies will give due consideration to Tribal concerns, including impacts on Indian trust assets and treaty rights and potential impacts to cultural resources.

The lead agencies invite Federal, State, and local agencies, along with Tribes and other stakeholders that may be interested in or affected by the proposed Husky 1 North Dry Ridge Mine to participate in scoping. Agencies with regulatory authority or special expertise, if eligible, may request or be requested by the BLM and Forest Service to participate in the development of the environmental analysis as a cooperating agency.

Request for Identification of Potential Alternatives, Information, and Analyses Relevant to the Proposed Action

BLM and Forest Service request assistance with identifying potential alternatives to the Proposed Action to be considered. As alternatives should resolve a problem with the Proposed Action, please indicate the purpose of the suggested alternative. The BLM and Forest Service also request that potential impacts that should be analyzed be identified. Impacts should be a result of the action; therefore, please identify the activity and the potential impact that should be analyzed. Information that reviewers have that would assist in the development of alternatives or analysis of resources issues is also helpful.

Lead and Cooperating Agencies

The BLM and Forest Service are joint lead agencies. U.S. Army Corps of Engineers, Idaho Department of Environmental Quality and Idaho Governor's Office of Energy and Minerals are cooperating agencies.
