BrightSource Solar Project Will Endanger Water Supply in Inyo and Nye Counties

BrightSource Energy's proposed Hidden Hills Solar Electric Generating System (HHSEGS) is expected to significantly draw down local aquifers in California and Nevada, according to the California Energy Commission, unless the company can buy out local water users.   The solar project would be built on 5 square miles of privately owned land in California's Inyo County, right next to the border with Nye County, Nevada.  The facility would use nearly 45.6 million gallons of water each year for mirror washing and other services during operation, and up to 227.1 million gallons of water during the 29 month construction period.   The CEC's draft certifications would require the company to conduct well monitoring and offset its water draw by purchasing over 53 million gallons each year to restore the Pahrump Valley Groundwater Basin.

The facility's water draw could affect desert springs along the historic Old Spanish Trail that used to provide relief to weary desert travelers and a reliable source of water for wildlife.  Nearby Stump Spring in Nevada still supports season pools 30 to 70 feet long and 1 to 2 feet deep, and has "significant wildlife value," according to the CEC, while other springs are believed to be largely dry due to heavy agricultural pumping. The CEC staff assesses that HHSEGS "would not be expected to have a measurable impact to the Amargosa River or its tributaries," although the preliminary assessment also acknowledges a lack of data needed to make a more confident determination.

Inyo County has expressed concern regarding the project's financial burden on the area, since providing emergency and other services to the remote site is expected to cost Inyo County 11 million dollars during construction, and 1.7 million dollars annually during operation, according to documents submitted to the CEC.

How Many Plants Species in the Desert?

Would you expect that California's desert hosts gives the redwood forest a run for its money when it comes to plant biodiversity?  It's easy to take the desert for granted when all you want to do is zoom through it on the highway and get to your destination. But you are passing by an amazing and biologically diverse ecosystem.  There are at least 2,450 native plant species found in California's desert, according to a great article by Chris Clarke on desert life , posted at KCET. If you want to learn more about our amazing deserts, join Desert Biodiversity, a new organization dedicated to exploring, respecting and defending the deserts.

Mowing Vegetation as Mitigation: Trump Administration Practice Goes Unchallenged

Image
The Trump administration is again touting the practice of mowing thousands of acres of desert vegetation as environmentally-responsible, despite a preponderance of evidence to the contrary.  The draft environmental review of the Yellow Pine Solar project in southern Nevada claims that vegetation mowing - as opposed to bulldozing - will yield positive outcomes that are highly doubtful.   This positive framing of the construction practice misleads the public and decisionmakers and ignores decades of scientific research regarding the impacts of mechanized disturbance on desert wildlands.  According to the draft environmental review: "Mowing is becoming the standard on large site-type ROWs to prevent permanent impairment of public lands (as mandated by FLPMA) and in lieu of off-site mitigation... Mowing methods are designed to help preserve soils, biological soil crusts, soil seed banks, native perennial vegetation diversity and structure, and cacti and yucca species, and to resist

The Absurdity of the Cadiz Water Export Scheme

Image
The Department of Interior this month reversed a policy to make it easier for the Cadiz company to pump billions of gallons of water from an ancient Mojave Desert aquifer - killing off natural springs that wildlife depend upon - to ship that water to the lush landscaping of Orange County.   Cadiz still has other hurdles in its way, but the company's tenacity and willingness to line the pockets of politicians could spell doom for Mojave wildlife. Cadiz Calls it Conservation The Cadiz company has a contract to export nearly 16.3 billion gallons (yes, that is billion with a 'b') a year for 50 years from the Mojave to the Santa Margarita Water District ( SMWD ) in Orange County.  The Cadiz company claims that it will only pump water that would otherwise evaporate from a dry lake bed and that the aquifer will naturally recharge from rainfall, leaving no significant impacts on wildlife or groundwater levels.  According to Cadiz propaganda, this isn't a water export sche
