Rare earth elements include the 17 lanthanides (La through Lu on the periodic table), plus scandium and yttrium. They are actually not all that rare and often occur together. However, they tend not to be concentrated in easily exploitable ore deposits, and they are difficult to separate out from their ore bodies. The Moun- tain Pass reserve is considered the richest site worldwide discov- ered to date. Since its closing, China has produced over 95% of the world’s rare earth elements. Mined nearly continuously since 1952, Mountain Pass ceased operations in 2002 except for minor processing of stockpiled ore after a series of environmental problems and increasing competi- tion from China. Now, after a lengthy process to permit a 30 year expansion plan, the latest owner, Molycorp, Inc., broke ground in January 2011 for an extensively reworked extraction and process- ing site. Molycorp states they will be mining fresh ore at the site some time in 2011 and will be operating at full capacity by the end of 2012. Mining rare earth elements is inherently risky. Radioactive ores often occur along with the rare earth elements.

But age isn’t Weverything. This 1.6 million acre wonderland is the third largest national park unit in the lower 48 states, smaller only than Death Valley and Yellowstone. Superlatives abound: the world’s largest Joshua Tree forest, 600-foot tall singing sand dunes, rugged “sky island” mountain ranges covered with pinyon-juniper forest, nearly 700,000 acres of designated wilderness, and rocky, sandy soils cov- ered with purple, blue, red, and pink carpets of flowers in spring. The Preserve is also renowned for its exceptional wildlife viewing, being a sanctuary for iconic species such as the desert tortoise, des- ert bighorn sheep, golden eagle, kit fox, and mountain lion. Although the Preserve is not widely known, it has developed a dedicated following. In 2009, several grassroots efforts to pro- tect and promote the Preserve came together to create a friends group. This effort was led by a diverse group of civic leaders, con- servationists, businessmen and women, writers, artists, and land CRAIG DEUTSCHE owners within the Preserve.

Mountain Pass is within the unincorporated portion San Bernardino County along Interstate 15 approximately 30 miles northeast of Baker and approximately 14 miles southwest of the Nevada stateline. The proposed quarry and waste rock areas would add 696 acres of disturbance to the existing mine site, resulting in a total disturbed area of approximately 1,044 acres. sag_> This document has been prepared to meet the State requirements of the California Environmental Quality Act.

  • Producers Case Study the Changing
    Producers Case Study The Changing Geography of Rare Earth Element Production Introduction The locations where rare earth elements are produced changed repeatedly throughout the 1900s and early 2000s. This variation suggests that production is not determined primarily by the geographic location of rare earth ores. Instead, the location of mines and separation plants is driven by a combination of market prices, government policies, and the actions of producers and manufacturers. As a result where and how rare earth elements are produced could change in the future. Initial Rare Earth Metal Production Although a mineral containing rare earth elements was identified in Sweden in 1788, it took more than 100 years for the first significant industrial product to be made using the rare earths. In the 1890s chemist Carl Auer von Welsbach developed a mantle made of a mixture of 99% thorium and 1% cerium for use with gas streetlights. More than five billion mantles were sold worldwide through the 1930s. Welsbach also developed mischmetal, a mixture of rare earth elements cerium, lanthanum, neodymium, and praseodymium. When alloyed with iron, mischmetal produced a metal that sparked when struck. It was widely used in pocket cigarette lighters as well as automobile ignition switches. The Welsbach Company mined rare earth deposits located in coastal sands in Brazil, India, and North Carolina. India’s coastal sands are also rich in the radioactive element thorium, which is not a rare earth element. India banned the export of these sands in 1948 to preserve its thorium supply for a potential nuclear energy program. At that time the price of rare earth metals spiked until newly established mining locations briefly made South Africa the world’s leading exporter of rare earth ores in the 1950s.

We strongly oppose the issuance of this preliminary permit. We have a number of concerns about the application by Premium Energy Holdings, LLC, particularly with regard to the potential impact of activities that could be granted under the preliminary permit on sensitive federal lands, which are eligible for inclusion in the National Wilderness Preservation System, and which are currently classified as Inventoried Roadless Areas, Wilderness Study Areas, and eligible Wild and Scenic Rivers. The proposed project would be located on public lands with highly sensitive resources managed by the U.S. Forest Service (Sequoia National Forest) and the Bureau of Land Management (BLM), state lands managed by the California Department of Fish and Wildlife, as well as lands owned by Non-Governmental Organizations and other private lands.

Collectively, we have been engaged in the forest plan revision process for these three national forests since initiated in 2012. Many of our organizations also have a long history of engagement in forest planning beginning with the first plans adopted in the late 1980s to early 1990s for national forests in the Sierra Nevada. We have embraced the new Planning Rule and taken seriously its invitation to provide feedback early in the process and throughout the development of the revised plans. We remain committed to working with your agency to develop revised forest plans that protect sensitive resources, provide for ecological integrity, and provide high quality recreational experiences. Our detailed review of the draft plans and DEIS indicate that there are significant gaps in assessment, development of plan components and evaluation of environmental consequences that preclude a meaningful analysis of the effects of the draft plans and alternatives on the environment. We ask that you revise the draft plans and revise or supplement the DEIS and circulate these documents for a 90-day comment period. Please contact Susan Britting (530-295-8210; [email protected]) if you have questions about these comments.

The responsible official for the Inyo plan revision is Tammy Randall-Parker, Forest Supervisor, Inyo National Forest. We are also objecting to the list of Species of Conservation Concern adopted by Regional Forester Randy Moore. Collectively, the objecting organizations have provided substantive formal comments throughout the forest planning process for the Inyo National Forest on the objection issues we raise below. We are deeply invested in securing a forest plan for the Inyo National Forest that protects important natural resources and provides for people. This objection covers a variety of issues related to resources affected by the revised forest plan and offers recommendations on how objection issues could be resolved. We appreciate the opportunity for review and possible resolution of issues contained in this objection prior to the approval of the final plan. We look forward to an opportunity to discuss our concerns with you.
