Oppose the Copper Rays Solar Project!
Sample Letter to Send Below
Copper Rays Solar, LLC has applied to the Bureau of Land Management (BLM) Pahrump Field Office for a right-of-way for the construction and operation of a proposed solar facility and interconnection to the regional transmission system (GridLiance). The Copper Rays Solar Project would be a photovoltaic solar power project including a battery storage facility on BLM-managed public land in Nye County just south of Pahrump and 40 miles west of Las Vegas. The Copper Rays Solar Project includes up to a 700 megawatt (MW) photovoltaic generating facility with energy storage on approximately 5,127 acres (8 square miles) of BLM-managed public land. The Copper Rays Solar Project would cover the desert habitat with photovoltaic panels. The electricity would be delivered to the Gamebird Substation and export all energy to California. The BLM has already approved the Yellow Pine Solar Project with grave impacts to the desert tortoise and has plans to sacrifice a total of 18,000 acres (nearly 30 square miles) for 5 solar projects in this part of of the Mojave Desert.

Degrading Desert Tortoise Habitat on Public Lands
The proposed Copper Rays Solar Project is located in the Eastern Mojave Recovery Unit for the federally threatened Desert tortoise (Gopherus agassizii) . Even with adequate monitoring the development and operation will likely kill, injure and displace several individual desert tortoises.

In April, 2021, Leeward Renewable Energy, LLC contracted the Newfields biological consulting company to conduct a presence/absence survey for desert tortoises on the proposed 5,100- acre Copper Rays Solar Project located directly north of Yellow Pine Solar. While the drought hampered survey results, they still did locate many live tortoises on the site. During the April 1st through April 8th, 2021, 55 adult live tortoises were observed, and 5 juveniles were observed. Total amount of desert tortoise burrows observed was 1,206. The estimated number of tortoises throughout the action area was calculated to be 137.
All tortoises would be excavated from their burrows and translocated to the Stump Spring Translocation Area across the Tecopa Road, and the Trout Canyon Translocation Area. Recently, the translocation for the adjacent, approved Yellow Pine Solar Project resulted in the predation of 30 of the moved tortoises by badgers which are not common desert tortoise predators. This could very well be because they moved the tortoises during a record- breaking drought year and the badgers were desperate for food. Common problems that result from translocation of desert tortoises include:
  • Predation - Savvy predators like coyotes will often keep track of recently moved, disoriented desert tortoises, and they have reduced tortoise numbers on certain translocation projects. A bigger problem on drought years. Ravens also search out newly-moved tortoises.
  • Overheating (Hyperthermia) - Translocated tortoises often become disoriented and will seek out their former homes. In many cases, tortoises overheat doing this. They have been observed pacing recently built fences searching for former burrows and water sources. Tortoises are ectothermic (cold-blooded) and do not internally regulate their body temperature that well.
  • Lack of Reproductive Success - A recent Smithsonian study found that translocated male desert tortoises are not reproducing.
Two other examples of desert tortoise translocations that didn't go well are the 2005 Ft. Irwin National Training Center project and the 2013 Moapa Solar Project.

Has the desert tortoise population on the Copper Rays Solar site been undercounted?

The BLM issued a "High Priority" status for the Copper Rays Solar Project in August 2021. The report claims that the density of desert tortoises across the southern Pahrump Valley is 3.04 per square mile and it is basing the number on surveys that took place over 30 years ago. The recently approved 3,000 acre Yellow Pine Solar Project ended up moving 139 desert tortoises off of the site. But they only predicted that they would find 53 adult desert tortoises. Yet BLM found higher numbers on the Yellow Pine site during actual tortoise translocation.

Much of the Copper Rays site is even higher in elevation than Yellow Pine containing some Joshua trees. This would also indicate a higher desert tortoise density.

Clearly the BLM should require Leeward Renewables to go back to the drawing board and start brand new tortoise surveys.

The desert tortoise is now included in the global list of the top 50 turtle and tortoise species at greatest risk of extinction.

According to tortoise biologists: "Prevailing declines in the abundance of adults overall and in four of the five recovery units indicate the need for more aggressive implementation of recovery actions and more critical evaluation of the suite of future activities and projects in tortoise habitat that may exacerbate ongoing population declines. G. agassizii is now included in the list of the top 50 turtle and tortoise species at greatest risk." (from Allison, L. J. and A. M. Mcluckie. 2018. Population Trends in Mojave Desert Tortoises (Gopherus agassizii). Herpetological Conservation and Biology 13(2):433–452.)

Crushing Desert Ecosystems

According to the Plan of Development submitted to BLM by Leeward Renewables, the project would use traditional “disk and roll” clearing methods, not vegetation mowing. This "conventional grading” ends up clearing 100 percent of the landscape. Leeward is formerly known as the company First Solar and they are notorious for 100 percent clearing and creating fugitive dust disasters. The below left photo shows how they cleared away desert habitat for the Stateline Solar Project in 2015. Below right is the Playa Solar Project in 2015. Both are in Southern Nevada and both were cleared by First Solar.

Loss of Wildlife and Rare Plants
The proposed project would be developed on a diverse and undisturbed Mojave Desert habitat. The vegetation is characterized by creosote and white bursage mixed with mid-elevation Mojave Desert plants. The site supports a host of species such as burrowing owls, kit foxes, kangaroo rats, big galletta grass, fluff grass, Desert iguana, Parish club cholla, Mojave yucca, Joshua tree, California kingsnake, Pahrump buckwheat, American badger, western banded gecko, and beavertail cactus to name just a few.

Avian Lake Effect
Large numbers of bird mortalities have been detected on utility-scale solar projects, and many scientists believe that they are creating a polarized glare or lake effect that causes birds and insects to be deceived and collide with solar panels or simply dehydrate after landing. The avian impacts are not fully understood, but everyone seems to agree that this problem was underestimated during the initial boom to fast-track big solar on both public and private lands in the Southwestern US.

Data gathered from seven solar projects in the southern California desert and arid grassland habitats from 2012 through April 2016 show that 183 bird species have been killed at solar projects, a number that rises with new information. 3,545 individual birds were reported dead at solar projects.

The Copper Rays Solar Project would be built within 4 miles of Stump Spring and 30 miles from the Amargosa River and has the potential to attract birds.
Cultural Resources
The Old Spanish Trail was in use between 1829 and 1848. Spain searched for a trade route between New Mexico and California in the 1700s. Traders with mule caravans stopped here as early as 1829, using the area as a link from the abundantly watered flowing springs of Las Vegas -- "The Meadows."

Congress designated the area as part of the Old Spanish Trail in 2002. Several segments in Nevada are listed in the National Register of Historic Places.

The Trail was based on a prior Indigenous route. The valley has been home to the Paiute and Shoshone peoples for thousands of years, and the valley still holds cultural importance.

The trail goes through the Pahrump Valley and developing 5 massive solar industrial projects in the area will destroy the historic character of the region. Copper Rays Solar would be 2 miles from the Old Spanish Trail.


Impacts to Visual Resources

An 8-square-mile development (right) would be visible for great distances. The visual contrasts would be visible from over 25 miles away. Covering that much land with solar panels would completely change the entire landscape. The project would be visible from Mt Charleston, Highway 160, California wilderness areas such as the Kingston Range and the Nopah Range and will create a very unnatural change to the landscape.

A Reasonable Alternative








With all of the new construction projects happening in the Las Vegas region, renewable energy can be utilized on rooftops and above parking lots. The US Department of Energy says, “The number of U.S. households with rooftop solar is rapidly growing. The amount of grid-connected solar is expected to double in just two years. With this large number of PV homes in the U.S. and a continuing robust market for additional PV installations, an ever-increasing number of PV homes will likely be sold or refinanced.
Fugitive Dust!!
Dust control in hot, arid climates is very problematic. The removal of established vegetation, biological soil crusts and centuries old desert pavement creates opportunities for dust to be airborne every time the wind blows. Not only does fugitive dust create problems for visual and biological resources, it creates issues for public health as well. In 2013, 28 workers were sent home with valley fever during the construction of the Topaz Solar Project in California. The above photo shows out of control dust from the Sunshine Valley Solar Project, Amargosa Valley, Nevada construction - 2019.
Water

Leeward Renewables has not said how much water would be needed for construction and operation. At 5,100 acres, the project would probably need over 1,300 acre feet for construction and over 20 acre feet a year for operation. Basin 162, the Pahrump Valley is over-drafted by 12,000 acre-feet. Use of water for this project and others could eventually cause residents to have to sink their wells and more groundwater decline would kill local mesquite in the area.

There are Western Honey Mesquite (Prosopis glandulosa) located on the northeast side of the project site (above right). These trees have been impacted by water drawdown but still are a unique ecological part of this desert that should be avoided. They provide habitat to several species. Mesquite trees furnish shade and wildlife habitat where other trees will not grow. They will often be found in alkaline soils near water holes. Although a single flower of the blossom is only a few millimeters long, they are clustered into a yellow creamy blossom attracting many different types of pollinators. At the Copper Rays Solar virtual meeting, the BLM stated they did not know if they would require the project to avoid the mesquite habitat.
Sample Letter to Send to BLM
The BLM will be accepting comments on the Copper Rays Solar Project application until January 7th, 2022.

Comments can be sent to: BLM_NV_SND_EnergyProjects@blm.gov or mailed to at BLM Southern Nevada District Office, Attn: Copper Rays Solar Project, 4701 N. Torrey Pines Drive, Las Vegas, NV 89130 .

Below is a sample letter you can copy and send to BLM. Please personalize the message to give them a diverse selection of comments. Your own ideas will make a difference to them when considering comments.

"Please reject the application for the Copper Rays Solar Project.

Approval of the project would result in the removal of over 49,000 Mojave yuccas as well as cacti and Joshua trees which are not known to return after being bulldozed. Many of the plants are hundreds of years old and provide habitat and food to the wildlife of the area.

The project site is located in important desert tortoise habitat. Leeward Renewables did their desert tortoise survey in April of 2021 - a record breaking drought year - not optimal conditions for tortoise surveys. When desert tortoises were moved off the Yellow Pine Site in May, 2021 just to the south of the Copper Rays site, nearly 3 times more tortoises than predicted were found and 30 of the 139 moved were killed by hungry badgers in drought conditions . Please do not allow a repeat of the recent desert tortoise disaster that took place on the Yellow Pine Solar site. Please require Leeward Renewables to conduct new tortoise surveys.

The project site contains old biological soil crusts and desert pavement that is about 100,000 years old. Removal of the desert surface will result in uncontrollable fugitive dust. This will impact public health in nearby Pahrump, Nevada.

The project site contains hundreds of rare Parish Club Cholla, scattered Joshua trees, kit fox, desert iguana, burrowing owl, coyote and several other species. Millions of living organisms would be killed in the construction of the project.

The project will probably require over 1,300 acre feet of water for construction and aditional acre feet each year for operation. The Pahrump Valley Basin is over-drafted by 12,000 acre feet.

The project will destriy habitat for mesquite and associated species, a very unique groundwater dependent habitat.

Solar projects can mimic lakes and will often kill a number of bird species. The project would be in the vacinity of Stump Spring and the Amargosa River which attract several birds.

The project would be located near the Old Spanish National Historic Trail. Developing 5 large solar industrial projects in the area will destroy the historic character of the region.

The project will cut off access to over 8 square miles of public land and be visible from recreation trails, Highway 160, Mt. Charleston, the Kingston Range Wilderness in California and the South Nopah Range Wilderness also in California.

The project application recieved a High Priority status becuse BLM claimed it has low conflicts. But the BLM can change that status and cancel the review of this project based on new information. The higher than predicted population of desert tortoises on the Yellow Pine Solar site to the south could be the information used to cancel the review of this application.

To preserve diverse Mojave Desert Habitat on public lands and the quality of life in Pahrump, Nevada, BLM should reject the application for the Copper Rays Solar Project."
