Crescent Peak Wind Project to Start Review on Border of Castle Mountains

Castle Peaks

^No place for a wind project: border of Nevada and California with Joshua trees and desert grassland, next to Castle Mountains National Monument.

March 15, 2018 - Southern tip of Nevada - The 32,000 acre Crescent Peak Wind Project, located right on the border of Mojave National Preserve and the new Castle Mountains National Monument is now undergoing a 90 day scoping period in the Federal Register. Notice of Intent here:

The impacts to the scenery will be significant, so that the Bureau of Land Manageent (BLM) will need to downgrade the Visual Classification to approve the project.

We have submitted a nomination to the BLM to designate the entire project site as an Area of Critical Environmental Concern. This will be looked at under the review for the Southern Nevada Office Resource Management Plan.

Conservation Designation Proposed by Groups

February 5, 2018 - Basin and Range Watch wrote a petition to Bureau of Land Management (BLM) to nominate public lands in the Piute Valley, Castle Mountains, New York Mountains and McCullough Mountains for status as an Area of Critical Environmental Concern (ACEC). These lands are
primarily located in Clark County, Nevada and are roughly 38,000 acres in extent. Part of the revision of the Southern Nevada Resource Management Plan, we are taking this opportunity to seek heightened conservation status for this area, which is threatened by urban development, mining, and the Crescent Peak Wind Project proposal.

^Map of proposed ACEC.

The Castle Mountains contain a unique arid grassland community in both California and Nevada. This area contains the only stands of diverse C4 perennial grasslands west of the Colorado River, subtropical grasslands that are normally found in the Sonoran Desert uplands in Arizona and Mexico. Grass species common in this plant community flower and seed during the warm seasons of summer and fall, especially after strong monsoon rainfall events. Normally found in the Sonoran Region, and even as far east as the Great Plains, grasses such as Black grama (Boutelua eriopoda), Blue grama (B. gracilis), Sideoats grama (B. curtipendula), are found in this corner of the Mojave Desert uplands, ranging into a small area of adjacent California in the Castle Mountains National Monument and Mojave National Preserve. This arid summer monsoon grassland community grades below into diverse creosote scrub (Larrea tridentata) and above into Blackbrush scrub (Coleogyne ramosissima) and one of the world’s largest Joshua tree woodlands (Yucca brevifolia), providing a
wide diversity of habitats for reptiles, birds, and mammals.

^Blue grama (Bouteloua gracilis) in the Castle Mountains.

The new ACEC would be adjacent to the existing Piute-ElDorado Area of Critical Environmental Concern which was established to protect the desert tortoise. While the upper elevations of the ACEC are too high to be good tortoise habitat, the lower eastern half would be quite suitable and protect connectivity habitat for the species. The region also contains the highest known density of golden eagles in the region. In February, 2016, President Obama signed the new Castle Mountains National Monument into law. The Monument protects 22,000 acres of public lands on the California side and is surrounded by the Mojave National Preserve, the third largest unit of the National Park system in the Continental United States. The scenic Castle Peaks are adjacent to this ACEC proposal. On the Nevada side is Walking Box Ranch, a historic cattle ranch purchased by
Hollywood actors Rex and Clara Bow in 1931. In 2005, the BLM purchased the Walking Box Ranch with a grant from the Southern Nevada Public Lands Management Act. The entire region is in view of Spirit Mountain, the Place of Creation for many Colorado River Indian Tribes. The Monument Proclamation recognizes a diversity of natural values found on the Nevada side of its border, including sacred values. For example, the Proclamation states, “Views from Hart Peak encompass vast wilderness and distinctive peaks, including Spirit Mountain in Nevada, a sacred site to many Native American tribes. The remoteness of the Castle Mountains area offers visitors the chance to experience the solitude of the desert and its increasingly rare natural soundscapes and dark night skies.”

Dear Tim:

As part of the input process into BLM’s Revised Resource Management Plan, the following
organizations and individuals are petitioning that a new Castle Mountains ACEC be designated
in the Paiute/Castle Mountains Region and that this be included in the preferred alternative for
the Revised Plan. These lands are primarily located in Clark County, Nevada and are roughly
38,000 acres in extent. The attached nomination describes the significant environmental and
cultural resources and values of these lands, and the need for special management attention. The
Paiute-Castle Mountain region contains important habitat that supports a variety of rare and
important species as well as important visual and cultural resources. It is our collective viewpoint
that designation of this area as an ACEC is the best alternative for this ecologically important
and sensitive area.

Crescent Peak Wind Proposal Pushed Ahead by BLM

Crescent Peak

^Crescent Peak Hills, Nevada, site of a prposed wind project. This is adjacent to the new Castle Mountains National Monument.

May 14, 2017 - According to documents obtained by the Freedom of Information Act (FOIA), the Bureau of Land Management (BLM) is putting out a supplemental Environmental Impact Statement (EIS) for the Resource Management Plan but will not consider the wind free request. The EIS would cover wilderness study, Areas of Critical Environmental Concern (ACEC's), solar energy, land disposal, Gold Butte, and socioeconomics. Basin and Range Watch sent in a request to BLM to examine a wind-energy-free zone in the Searchlight and Piute Valley region, accompanied by a petition with over 700 signatures. The Colorado River Indian Tribes also requested this. We believe it is legitimate for BLM to cover it in a Supplemental EIS.

There is a draft Notice of Intent (with mineral segregation) and BLM has a Press Release ready to go with no date on it were obtained as part of the FOIA documents we obtained. There is also a raptor survey indicating the area is full of eagles.

Here is the BLM Press Release ready to go:

BLM Seeks Comments for Crescent Peak Wind Project Near Searchlight

Las Vegas—The Bureau of Land Management (BLM) Las Vegas Field Office is seeking comments on the Crescent Peak Wind energy project proposed west of Searchlight, Nevada. The project would be built on approximately 32,531 acres of Federal land managed by the BLM.  A Notice of Intent to Prepare an Environmental Impact Statement was published in the [INSERT DATE] Federal Register.

The Las Vegas Field Office will prepare an environmental impact statement (EIS) for the project.  Publication of the notice in the Federal Register initiates the beginning of the scoping process to identify issues. Scoping meetings will be announced at least 15 days in advance through local media and on the BLM website at

The public is being asked to comment on Crescent Peak Renewables, LLC’s (CPR) proposal to construct, operate, and maintain a 175 to 500-megawatt (MW) wind generation facility. The point of interconnection would be at either the proposed Nipton substation to connect with the existing Southern California Edison Eldorado-Mojave 500-kV transmission system or to the proposed RWITZ substation to connect to the Valley Electric transmission system. CPR has worked with the California Independent Systems Operator (CAISO) on plans for interconnection and delivery of energy into the California market.

Written comments may be mailed to the BLM, Southern Nevada District, Renewable Energy Project Manager, 4701 N. Torrey Pines Drive, Las Vegas, NV 89130, or emailed to For more information, please call Greg Helseth at (702) 515-5173.

Plan of Development Submitted

^Map from the December 2015 Plan of Development; we added the names of the national park units, including the new Castle Mountains Natuional Monument which is no longer BLM land.

December 20, 2016 - Basin and Range Watch obtained an older version of a Plan of Development (December 2015) from the Bureau of Land Management (BLM), that was submitted by the company in the process of seeking a lease permit on public land. BLM told us they expect to receive an updated Plan of Development soon and BLM will release a Notice of Intent to start environmental review.

We see an uphill path for this project since the company is seeking to build a 17,000-acre wind project right along the boundary of two beloved National Park Units: Mojave National Preserve and the new Castle Mountains National Monument. 500-foot tall wind turbine generators would be built on the northern New York Mountains, Castle Mountain hills, and McCullough Range (into the pinyon-juniper woodlands) in part using helicopters for heavy lifting construction.

Plus, California utilities and the California Independent System Operator are not interested in buying low-quality wind from this area. They are seeking high-quality wind from the Great Plains wind resource areas in Wyoming, Colorado, and New Mexico, via long transmission lines such as TransWest Express. The state is having an overgeneration problem now and looking farther afield for renewable energy.

Eagle Surveys

May 23, 2016 - The applicant for the Crescent Peak Wind Project is doing eagle surveys right now, according to Bureau of Land Management (personal coomunication), which is not following protocol. Using the contractor SWCA, surveys right now are to look for birds and bats, including eagles. US Fish and Widlife Service protocol for eagle nest surveys calls for surveys to be done in Fall and Winter for this geographic area. This is when eagles are beginning to nest. By May eagles have often flegded and nests may be unoccuppied. The applicant should be undertaking eagle nest surveys starting in November-December-January of 2016.

Wind Project Moving Forward

April 23, 2016 - Crescent Peak Wind Project Update: Eolus Wind has submitted a Draft Notice of Intent (NOI) for the Crescent Peak Wind Project to be reviewed by the Bureau of Land Management. An NOI is the first stage of an official federal review of a big project like this. The BLM has placed the NOI on hold until October 1st, 2016 due to other large pending projects including a land exchange with Nellis AFB. But we could be engaged in this issue this coming fall.

The Crescent Peak Wind Project would be built on Nevada public lands and be adjacent to the Mojave National Preserve and the new Castle Mountains National Monument in California. It would surrond the historic Walking Box Rance and be visible from Searchlight, Nevada. A wind project surrounding Searchlight has been held up due to golden eagle and other wildlife threats.

Three New National Monuments in the California Desert

^Looking eastward from the California-Nevada border inside the new Castle Mountains National Monument. A proposed wind project would be placed on the hill to the left if allowed to go forward by Bureau of Land Management.

February 18, 2016 - Castle Mountains National Monument was officially designated on February 12 by President Obama using the Antiquities Act after more than a decade of legislative work by Senator Dianne Feinstein (D-Calif.), as well as advocacy work by many environmental groups. Mojave Trails National Monument, Sand to Snow National Monument, and Castle Mountains will protect 1.8 million acres of desert lands. The Mojave Trails National Monument, at 1.4 million acres, links Mojave National Preserve and Joshua Tree National Park, adding protection for important connectivity corridors for wildflife. All three monuments had proposed large-scale renewable energy projects over the years, so these designations permanently conserve desert ecosystems, cultural resources and history from energy threats.

The Castle Mountains were originally carved out of the Mojave National Preserve when it was established because of an operating gold mine, and now 20,900 acres will be added back to a more protected status, managed by both the National Park Service and Bureau of Land Management. Mojave Trails National Monument will be managed by the Bureau of Land Management, and Sand to Snow National Monument will be managed jointly by the Bureau of Land Management and the U.S. Forest Service.

Reactivated Wind Project Threat to Castle Mountains Area

^Crescent Peak in the northern part of the New York Mountains, just outside the boundary of the Mojave National Preserve and adjacent to the proposed Castle Mountains National Monument. This scene is in the heart of a large industrial wind project application which has been reactivated.

February 5, 2016 - Clark County NV - Will there be a wind project next to the proposed Castle Mountains National Monument and Mojave National Preserve? Ironically, the new Castle Mountains National Monument in California, which may be created soon, has a reactivated wind energy application right next to it in Nevada. Eolus Wind has bought the applications for the Crescent Peak Wind Project (and Comstock Wind to the north near Virginia City, NV) and intends to file a Notice of Intent to prepare an Environmental Impact Statement with the Bureau of Land Management soon. The application spans nearly 40,000 acres and would be visible from the Castle Peaks, Wee Thump Wilderness, Walking Box Ranch, several Parts of the Mojave National Preserve, and Spirit Mountain. Eolus is saying they may want to use the newer 750 foot concrete based turbines which would be highly visible form the Mojave National Preserve.

^Joshua trees (Yucca brevifolia) on the wind project site.

The wind proposal would be visible from Nipton, surrounded by the Wee Thump Wilderness and would border the Mojave National Preserve, all hugging the Nevada border. The Bureau of Land Management is expecting a revised plan of development and the company will be undertaking raptor surveys.

The Swedish company Eolus just reactivated a dormant application from Oak Creek Wind and have not yet started the environmental review process.

In order to get the NOI in the Federal Register, they need to submit an updated Plan of Development to BLM which they have not done yet. It will take BLM about 2 months to decide if the plan will will be good enough to start National Environmental Policy Act review.

The project is about 40,000 acres, however, the new owner is saying the final project will be anywhere from 50 to 200 MW.

Standard turbines (450 feet tall) may be considered outdated technology. The utilities are far more interested in photovoltaic solar projects. So this company wants 4 megawatt turbines which would be 750 feet tall. There is a demonstration project using these in Iowa, and we have seen on at Tehachapi Pass in CA. This would be an even larger visual intrusion to surrounding landscapes than older large wind turbine generator models.

Eolus told BLM it would take five years to complete all surveys and they would not start construction until 2021.

^Public access dirt road on BLM land on the Crescent Peak wind project site; this road would need to be widened for construction traffic. The wind project would also possibly sit on the distant foothills of the McCullough Mountains in the background.

^Very large wind turbine generator on the left under construction on Tehachapi Pass CA, which may be similar to the design sought by Eolus at the Crescent Peak area. These would be visible from a huge distance away.

The BLM said that they may want to use less turbines due to the super size of this new mega-concrete turbine. Eolus told BLM there could be as few as ten for this project. The question is where would they put a small project in that 38,000 acres? Possibly around Crescent Peak. It is full of patented mining claims and active mines, and BLM would consider that the most disturbed area. But even at 4 MW, ten would only give them 40 MW.

The Las Vegas Resource Management Plan noted that the Piute Valley (east of Crescent Peak) should be managed for its solitude and primitive recreation opportunities.

Here is the promotional link:

Through its recently established North American subsidiary, Sweden-based developer Eolus has acquired two wind power projects under development in Nevada. The transaction means that Eolus will acquire 100% of the shares in the U.S. companies Crescent Peak Renewables LLC and Comstock Wind LLC for the sum of $50,000.

According to Eolus, Crescent Peak owns the rights to a project between 200 MW and 600 MW under development in Clark County, and Comstock owns the right to a project between 20 MW and 100 MW under development in Storey, Washoe and Carson City counties. The transaction includes a profit sharing mechanism for the future sale of the wind projects.

Mojave National Preserve Threat

^Castle Peaks.

January 7, 2013 - The Oak Creek Energy Systems (OCES) application to the Bureau of Land Management (BLM), Las Vegas Field Office, for a right of way grant to conduct meteorological studies on public lands, was approved a few years ago. The application involves the installation of meteorological towers to collect atmospheric data for a period of 2 to 3 years, about 10 miles west of the town of Searchlight, Nevada. OCES will collect data on wind speed and direction, wind shear, temperature, and humidity.

The project is located in the Castle Mountain area on the Clark County, Nevada-San Bernardino County, California boundary, bordering the Piute-Eldorado Valley Area of Critical Environmental Concern and several wilderness areas. We called BLM and they said it will also go into California. It will be adjacent to the Mojave National Preserve in the Castle Peaks mine area, in the keyhole next to the preserve.

Originally, there was a sister project to this one in the Castle Mountains keyhole in the preserve on the California side by the same company. That was thrown out. Now it is all in Nevada, but it will still be visible for hundreds of miles in the Preserve.

As of September 2012, the company changed to Crescent Peak Renewables LLC, a subsidiary of Oak Creek Energy Co. It determined that there might be feasible wind resources to develop a wind farm which would cover 37,740 acres next to Nipton, California, the Wee Thump Wilderness Area in Nevada, the McCullough Mountains Wilderness Area in Nevada, and the wind project would sit directly on a large portion of the northwest border of the Mojave National Preserve in California. The wind turbines would be visible both day and night from great distances the Mojave Preserve. At this point they are submitting their project for review under the Nevada Public Utilities Commission. This indicates that they are attempting to move forward with the Federal Review Process. The BLM has told us that this could make its way in the Federal Register soon.

^The most recent project map we have found. The project was removed from the "keyhole" within the Mojave National Preserve, but still lies next to the northeastern boundary.

The Castle Mountains area contains unique habitats called Monsoonal Mojave Grassland and Joshua Tree Savanna, found almost nowhere else in the desert. The area is rich in summer-flowering grasses usually found in the Southwest Deserts of Arizona, New Mexico, and Mexico. There are also Great Plains elements. All these mix with typical Mojave Desert plants, and well-developed Joshua tree (Yucca brevifolia) and Mojave yucca (Y. schidigera) stands.

Several species of Grama grasses (Bouteloua eriopoda, B. gracilis, B. barbata B. curtipendula) and Three-awn grasses (Aristida purpurea purpurea, A. p. longiseta) grow with Big galleta grass (Hilaria rigida), Bush muhly (Muhlenbergia porteri), Indian rice grass (Stipa hymenoides), Desert needlegrass (Stipa speciosa).

Shrubs are very diverse, and include not only Creosote bush (Larrea tridentata), but also Winterfat (Krascheninnikovia lanata), Apache plume (Fallugia paradoxa), Ephedra (Ephedra spp.), Paperbag bush (Salazaria mexicana), Cliff rose (Purshia mexicana), California buckwheat (Eriogonum fasciculatum), Blackbrush (Coleogyne ramosissima), Wolfberry (Lycium spp.), Four-wing saltbush (Atriplex canescens), Desert almond (Prunus fasciculata), Matchweed (Gutierrezia sp.), and Desert sage (Salvia dorrii). Washes have White bursage (Ambrosia dumosa), Cheesebush (Hymenoclea salsola), and Desert willow (Chilopsis linearis).

A savanna of Joshua trees and some juniper grow in the grassy hills and valleys. Both Mojave yucca and Banana yucca (Yucca baccata) grow with cacti: Calico cactus (Echinocereus engelmannii), Buckhorn cholla (Cylindropuntia acanthocarpa), Pancake prickly-pear (Opuntia chlorotica), and Old man cactus (Opuntia erinacea).

On our field trip in October 2009 we saw Rock wrens, Gambel's quail, and Barn swallows and Violet-green swallows flying. Bighorn sheep use the area, and the park is considering re-introducing Pronghorn antelope to the grassland.

Environmental groups such as the California Wilderness Coalition and National Parks and Conservation Association are working to request Congress to add this "keyhole" area surrounded by parkland to Mojave National Preserve. Such a rich ecosystem deserves protection. It is currently managed by Bureau of Land Management with a played-out open-pit gold mine -- the Viceroy Mine -- that could be interpreted by the park for its historic value. The mine area could be reclaimed. The 30,000 acres of the Castle Mountains area must be made part of the park by an act of Congress, and letters to congressmen can help to make this happen.
