Duke Energy to build fully lined coal ash landfills at Dan River and Sutton Plants - Duke Energy

CHARLOTTE, N.C. -
On site and on time – that’s the plan for storing millions of tons of coal ash from two North Carolina power plants.
Duke Energy plans to submit permits to construct fully lined on-site landfills at the Dan River Steam Station in Eden, N.C., and the Sutton Plant in Wilmington, N.C. The landfills will be located on plant property and will provide a permanent storage solution for more than 6 million tons of coal ash at the two sites.

Comparing the Baltic Sea and Chesapeake Bay Provides Lessons for More Cost-Effective Policies

From the #USDA:

USDA's Economic Research Service, and other researchers, analyzed the similarities and differences of the Chesapeake Bay and the Baltic Sea to help preserve the water quality of each.
Situated on two different continents and separated by thousands of miles, the Chesapeake Bay on the East Coast of the United States and the Baltic Sea in northern Europe face remarkably similar problems. Both are relatively shallow basins of brackish water. Both marine areas suffer from eutrophication–pollution caused by introduction of chemical nutrients. For both water bodies, agriculture is the single most important source of those nutrients, and governments have implemented policies to reduce nutrient loads and improve marine ecosystems.
Researchers at the Natural Resources Institute Finland, USDA’s Economic Research Service, and the University of Helsinki have analyzed the similarities and differences between the institutional settings and protection policies of the Chesapeake Bay and the Baltic Sea. The aim was to identify avenues for reducing the cost of meeting water quality objectives. The very different political and institutional histories of the jurisdictions within the respective watersheds provide both contrasts and similarities. The six U.S. States in the Chesapeake watershed have a common political history and operate under Federal environmental law. The Baltic watershed is made up of 14 nations whose intergovernmental relations are strongly influenced by Cold War legacies. Yet current policies in both watersheds rely heavily on voluntary approaches to control agricultural runoff.
Examining the policies and programs in place yields lessons for designing and implementing future policies to control nutrient pollution. First, flexible, market-like policy instruments promote innovation and are the most likely to achieve cost-effective pollution control. Water quality trading to meet pollution control goals is an example. Second, actively targeting agri-environmental programs to farms that can provide the biggest improvement in water quality per dollar spent can significantly reduce program costs. Third, a bidding process or auction to provide program payments, as in the Conservation Reserve Program, could also reduce pollution abatement costs.
Also among the researchers’ findings was that efficiency can be improved by rewarding results– nutrient reductions–rather than compensating farmers for the cost of implementing conservation practices. Although pollutant losses from agricultural lands cannot be easily measured, new field-scale modeling tools enable conservation payments to farmers to be based on estimated reductions in pollutant loads.
To design effective policies, program managers need to understand how on-farm management choices affect the nutrients reaching surface waters. And they need to understand what influences farmers’ management choices. As we improve our ability to make accurate predictions about how conservation measures work in different (and even distant) settings through research, we will be able to improve the cost-effectiveness of pollution abatement programs.
Check out our article for a fuller discussion of the Baltic Sea and Chesapeake Bay. ERS has recently released a report on policies for reducing agricultural pollutants to the Chesapeake Bay.
    

Sandhill Cranes

From Yellowstone National Park:




Reflected by hills, amplified by water: it doesn't take many sandhill cranes to fill the Swan Lake basin with sound.

Corallorhiza trifida (Early Coralroot)

From Mount Rainier National Park:




One of the most exciting moments in a naturalist's career is the discovery of a species they have not observed before. According to the experts, Corallorhiza trifida (Early Coralroot) is "rare at Mount Rainier....circumboreal, but is uncommon here in the northwest and recorded a couple of times apparently at the mountain...A terrific find!" Even more exciting for me is the fact that this rare Corallorhiza is also a partial mycoheterotroph, a highly specialized group of plants. I believe our mild winter may have allowed the mycorrhizal components of many mycoheterotrophic species to proliferate, thus bringing to the surface a greater number and variety of plants than we'd see in a normal year. ~cv

Going Wild about Water at the World Water Forum

From the .#USDA:


This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research profile.
Water is a precious resource and will become scarcer as the human population continues to grow.  In many areas, climate change is expected to affect weather patterns. In general, the wetter areas are expected to get wetter and the drier areas are expected to get drier. This year, California’s drought has highlighted how important it is for land managers and producers to exercise best practices to increase water quality and quantity so there is enough to go around.
This year, USDA participated in the 7th Annual World Water Forum in Daegu, Republic of Korea. Every three years, the World Water Council hosts the Forum and develops the program in cooperation with the private sector, governments, industry, international governmental organizations, nongovernmental organizations and academic groups.
USDA’s booth was part of the larger USA Pavilion at the Forum, along with our colleagues from USAID, Department of Interior, State Department, the US Water Partnership, and several other government agencies, private companies, and universities. We showcased the latest science and technology research being done at the Agricultural Research Service, the tools and best practices developed by the Natural Resources Conservation Service and the Forest Service to improve water quality and quantity, and two of the web interfaces we manage or contribute to that help land managers and producers find the information they need about water: the Climate Resilience Toolkit (toolkit.climate.gov) and the Regional Climate Hubs website (climatehubs.oce.usda.gov).  
We had such a diversity of visitors to our booth: from the mayor of a city in France, to university students, to industry representatives, to international delegations, to a retiree I had a really good conversation with about the history of American science. As I shared information loaded with the best USDA has to offer in water tools and practices, the first question many of them asked was whether the tools are free. Yes! And though some of the tools are examples that are specific to agriculture and ecosystems in the United States, the cutting edge ideas coming out of our agencies can still set an example for what is possible elsewhere. We were excited to participate in the World Water Forum and share.

Is the Foothill Yellow-Legged Frog in Hot Water - Because of Cold Water?

From the .#USDA:

For the foothill yellow-legged frog, breeding can be a challenging matter.
It is the only true frog in western North America that breeds exclusively in streams, preferring warm stream edges. Its eggs can be swept away with spring rains and rapid currents, so a relatively long breeding season allows mates to wait until weather and water conditions offer the best chance for eggs to develop and hatch in this dynamic environment.
But yellow-legged frogs face a new challenge in a Northern California river managed for agriculture, energy, and habitat for steelhead, Chinook salmon and coho salmon.
Researchers from the U.S. Forest Service Pacific Southwest Research Station (PSW) are investigating how cold water releases from dams on the Trinity River affect stream water temperatures and breeding success of the frog, whose populations are declining across California and Oregon.
PSW researchers and collaborators from the U.S. Fish and Wildlife Service monitored frogs in breeding sites along the regulated stretch of river as well as six unregulated tributaries. They documented the timing of breeding and then examined the development of embryos and tadpoles. In the colder, regulated water downstream from the dam, the frogs laid eggs later, the eggs hatched later, and tadpoles were smaller and leaner.
“These results may be attributed to effects of water temperature on frog development and growth, feeding rates, and food quality and quantity,” said Clara Wheeler, a PSW ecologist and lead author of the study.
In dammed rivers like the Trinity and other modified water systems, cold water releases do benefit some species, particularly those fish species that need cooler water for spawning and egg development. But these releases keep the water unnaturally cold in the summer—lowering temperatures by as much as 6.7 degrees Celsius (44.1 degrees Fahrenheit), researchers found—which puts the foothill yellow-legged frog and some other species at a disadvantage.
“Persistently depressed summer water temperatures appear to play a seminal role in inhibited tadpole growth and may be a factor in the decline of this population,” said Wheeler.
Previous research suggests that population declines are also linked to altered flow in these modified water systems.
With California in the midst of a severe, multi-year drought, the wise use of water stored in reservoirs will be critical, and water managers must decide how to balance the water use for agriculture and energy with the protection of fish and wildlife.
“This research informs managers that water temperature influences the fitness of early-stage foothill yellow-legged frogs, and emphasizes the importance of using a multi-species management approach when implementing environmental assessments and executing management decisions,” said Wheeler.
    

Southwestern Willow Flycatcher, Other Species Benefit from Riparian Restoration Work in Utah

From the .#USDA:

Jim Hook, owner of the Recapture Lodge and volunteer firefighter in Bluff, Utah, has been working for years to manage and restore the riparian habitat on his property along the San Juan River in southeast Utah.
Where the Cottonwood Creek and the San Juan River meet, Hook is working with USDA’s Natural Resources Conservation Service (NRCS) to establish healthy riparian habitat. His hard work over the years has begun to yield results as the invasive plants have begun to die and native plants are taking their place. An endangered bird species, the Southwestern willow flycatcher, is one of the species that will benefit from his restoration work.
The flycatcher prefers to nest in dense native trees and shrubs, but also nests in thickets dominated by tamarisk. Leaving dense tamarisk increases fire severity, frequency and size, which in the long term can degrade the habitat for flycatcher and many other species. An incremental removal of tamarisk and planning of native plants is more difficult, and more complex, but will yield the best short and long-term benefits for flycatcher.

Over the years, Hook has welcomed projects from researchers, students, agencies, biologists and artists on his land and allows hiking access to individuals with authorization. Hook has worked with NRCS for several years to make conservation improvements to his land, and when the Working Lands for Wildlife partnership, or WLFW, was created in 2012, his history of stewardship made him a good candidate for the program.
WLFW assists landowners, like Hook, in restoring degraded riparian ecosystems, conserving existing healthy riparian systems and improving working lands near riparian areas. The program focuses on increasing and improving potential breeding habitat, to support Southwestern willow flycatcher recovery.
NRCS provided Hook with technical and financial assistance, including the development of a conservation plan, which entails controlling invasive Russian olive trees, removing beetle-killed tamarisk trees, creating a fuel break and planting additional acres with native species to supplement the existing habitat. He completed most of the work himself.
Hook is continuing his work to restore native habitat. Project partners, such as Utah Department of Forestry, Fire and State Lands and Utah Conservation Corps have also contributed to the success of the project by providing funds and technical expertise. Hook, NRCS and the partners will continue to expand the restoration effort and monitor the riparian habitat, and they hope to see a nesting flycatcher pair in the upcoming years. 
Restoring habitat for the Southwestern willow flycatcher not only benefits the flycatcher but many other sensitive species, such as the yellow-billed cuckoo, northern leopard frog and Townsend’s big-eared bat. Eighty-four federally listed species, including the flycatcher, may benefit from conservation work in southwestern riparian ecosystems, including hundreds more not listed.
In late March, NRCS announced its plans to broaden the conservation opportunities available to producers, enabling more people to help wildlife while strengthening their agricultural operations.
