TDOT opens virtual-only Pellissippi Parkway extension comment period for two weeks
Written by Thomas Fraser
$20 million per mile: TDOT opens virtual-only comment on highly controversial roadway
The Tennessee Department of Transportation has opened a virtual-only public comment period for the controversial Pellissippi Parkway extension, which would slice through the remaining rural areas of Blount County and move urban expansion and increased traffic flow ever closer to the Great Smoky Mountains, one of the most biologically diverse areas on Earth.
The public comment period began April 15 and will last until April 25. The project has generated controversy and lawsuits for at least two decades, but TDOT decided the comment period should be held virtually for only two weeks because of the Covid-19 pandemic.
The project encompasses about four miles and will cost nearly $100 million. Opponents of the parkway say the extension is a waste of money and will destroy rural landscapes and wildlife habitat and pollute aquatic resources.
Here's a link to a story about the Pellissippi Parkway extension published in February by Hellbender Press.
According to The Daily Times, which reported the public hearings on April 19:
“'The COVID-19 pandemic has forced the department to look for alternate ways to engage and interact with the public,' TDOT spokesman Mark Nagi said in a video introducing the presentation, framed as a somewhat awkward-to-navigate virtual reality room.”
“It includes a history of the project, a right of way acquisition process overview, a project design summary and a comments and questions section. A digitally generated flyover video of the planned extension shows intricate details of how the road may look once completed.”
According to the TDOT website:
“The Tennessee Department of Transportation (TDOT) will host a Virtual Design public meeting from April 15, 2021, to April 29, 2021, to gather public input on the proposed project in Blount County on SR-162 Ext. (Pellissippi Parkway), from SR-33 to SR-73 (US-321).”
“The virtual meeting was opened to the public at 8:00 am EST on April 15, 2021 and will close at 10:00 pm EST on April 29, 2021. The website link is:
https://gather.cdmsmith.com/v/v8jkyAVO149.”
The proposed highway would require the acquisition of private property and extend through the Wildwood and Sam Houston areas to an abrupt terminus with East Lamar Alexander Parkway to the west of Walland, which is host to an increasing number of high-dollar hospitality attractions such as Blackberry Farm.
Right-of-way acquisitions could start by the end of the year, according to The Daily Times.
To the east of the proposed parkway's end is Townsend, which bills itself as the “Peaceful Side of the Smokies.”

Alabama is home to remarkably diverse ecosystems: They face dire threats.
This story was originally published by The Revelator.
When longtime environmental journalist Ben Raines started writing a book about the biodiversity in Alabama, the state had 354 fish species known to science. When he finished writing 10 years later, that number had jumped to 450 thanks to a bounty of new discoveries. Crawfish species leaped from 84 to 97 during the same time.
It’s indicative of a larger trend: Alabama is one of the most biodiverse states in the country, but few people know it. And even scientists are still discovering the rich diversity of life that exists there, particularly in the Mobile River basin.
All this newly discovered biodiversity is also gravely at risk from centuries of exploitation, which is what prompted Raines to write his new book, “Saving America’s Amazon.”
Vandals deface 1,200-year-old Cherokee and Creek rock carvings in North Georgia
NYT: Ancient Native American rock carvings vandalized in Chattahoochee National Forest
From the “this is why we can’t have nice things” file: Vandals violated ancient and sacred Cherokee and Creek art with scratches and paint in the Track Rock Gap area of Chattahoochee and Oconee national forests.
“It’s one of the most significant rock art sites in the Southeastern United States and the only such site located on public land in Georgia,” according to a National Forest Service Facebook post, the NYT reported. That post was later removed by the forest service, which cited the ongoing criminal investigation.
The rock carvings date to 800 A.D. The vandalism occurred at some point in 2020 or early this year.
There are at least 100 Native American petroglyphs in the north Georgia national forests. Some of the more prominent sites are fenced but allow people to view the ancient art.
Also from the Times report:
The Cherokee Tribal Heritage Preservation Office said in a statement that the Eastern Band of Cherokee people were “sad and frustrated” to learn of the vandalism.
“They are special sites for the Eastern Band of Cherokee Indians and for all people as part of the Heritage of this region,” the statement said. “Whether through ignorance or malice — the result is irreparable damage to a unique site that connects us directly to the people of the past.”
Ecological Society of America honors Oak Ridge National Laboratory scientists for sustainability research
Written by Thomas FraserORNL researchers receive 2021 Sustainability Science Award for mapping human influence on U.S. river and stream changes
Researchers from Oak Ridge National Laboratory mapped and quantified hydrological changes throughout the country due to urban development, energy production and other human factors and won a prestigious award for their efforts.
The team’s analysis was published in the Proceedings of the National Academy of Sciences and received the 2021 Sustainability Science Award from the Ecological Society of America.
“The Sustainability Science Award recognizes the authors of a scholarly work that make a substantial contribution to the emerging science of ecosystem and regional sustainability through the integration of ecological and social sciences. The researchers will be recognized during the society’s annual meeting in August,” according to an ORNL release announcing the award.
The research coupled U.S. Geological Survey stream-flow records with geospatial modeling to quantify human impact on national water resources and concluded the 7 percent of affected aquatic systems hold 60 percent of North American freshwater fish, mussels and other species.
“This work exemplifies how ORNL’s interdisciplinary research in environmental and geospatial science helps equip decision makers with the tools needed to move our nation toward a more sustainable future,” Stan Wullschleger, associate laboratory director for ORNL’s Biological and Environmental Systems Science Directorate, said in the release.
Lead author Ryan McManamay, an aquatic ecologist and faculty member at Baylor University, was with ORNL’s Environmental Sciences Division at the time of publication. Co-authors include ORNL’s Sujithkumar Surendran Nair, Christopher DeRolph, the late April Morton, Robert Stewart, Matthew Troia and Budhendra Bhaduri; Northern Arizona University’s Benjamin Ruddell; and the University of Tennessee’s Liem Tran and Hyun Kim.
“It was a privilege to work with this team that spanned across multiple disciplines and institutions,” said Bhaduri, an ORNL Corporate Research Fellow and director of ORNL’s Geospatial Science and Human Security Division. “Given the impacts of climate change, there has never been a more pressing opportunity to address environmental sustainability. It’s a tremendous honor to make this scientific contribution and to be recognized for it.”

Developer slams brakes on proposed Oak Ridge motorsports park
Knox News: Developer pulls Oak Ridge motorsports park proposal after pushback
In a victory for local environmentalists, the developer who proposed and pushed for a motorsports park on the western end of Oak Ridge has abandoned the project in hopes of finding a more “attractive” community.
The park would’ve been located in the Horizon Center industrial park and required the development of natural areas preserved via a city agreement with the Department of Energy.
Individuals and groups such as the Oak Ridge-based Tennessee Citizens for Wilderness Planning said the proposal was inherently inappropriate for the site, citing the loss of diverse, mature hardwood forest, and noise pollution.
At least $35 million headed to Smokies for southern Foothills Parkway overhauls and maintenance facilities improvements

Southern stretch of Foothills Parkway to get $33 million overhaul
The National Park Service will repave and improve the entire southern stretch of Foothills Parkway and design a replacement of the outdated maintenance facilities at Sugarlands thanks to funding from the Great American Outdoors Act.
Both projects will cost a combined $40 million and be paid for via a foundation established as part of the overall legislation passed by Congress in 2020.
The Department of the Interior will spend a total of $1.6 billion from the Legacy Restoration Fund this year alone as part of a long-range goal to improve infrastructure and catch up on maintenance needs in national parks and other federally managed lands, according to a release. National public lands across the country, including Great Smoky Mountains National Park, have long faced maintenance deficits totaling billions of dollars.
The Foothills Parkway and Sugarlands work is one of 165 deferred maintenance projects that will be funded this year. Infrastructure improvements are also planned for sections of the Blue Ridge Parkway and Shenandoah National Park.
The $33.6 million in planned improvements to the parkway between Walland and Tallassee (from mile marker 55 to 72) will include enhanced safety features and milling and replacement of the pavement.
“The road rehabilitation will include pullouts and parking areas, replacing steel backed timber guardrail, and repair, reconstruction and repointing of stone masonry bridge parapet walls and the walls along Look Rock Overlook,” according to interior department documents.
“Other work will include removing and resetting stone curb, replacing/repairing of the drainage structures, stabilizing roadside ditches, overlaying or reconstructing paved waterways, stabilizing and reseeding the shoulder, installing pavement markings, replacing regulatory and NPS signs, and constructing ramps with curb cuts to provide access to interpretive panels and to meet federal accessibility guidelines.”
“The work proposed in this project would reduce the hazards and improve safety for park visitors and employees,” according to the data sheet.
The Legacy Restoration Fund will also cover the $3.5 million cost of a design/build plan to improve and update the expansive and deteriorating maintenance yard at Sugarlands.
“The buildings, driveways, and parking areas associated with the maintenance yard have not been renovated or rehabilitated in decades,” according to a data sheet.
“There are safety hazards, inadequate space or capacity for park maintenance and operations personnel, and facilities that are entirely insufficient for essential park operations and maintenance. The condition of many buildings is so poor that replacement and disposal is likely the only practical option. This project will complete predesign project programming and budgeting and develop a Design Build RFP for the rehabilitation or replacement of facilities and associated utilities, parking, and grounds.”
Great Smoky Mountains National Park officials did not immediately respond to an email requesting additional information on possible future projects and to what extent national infrastructure plans proposed by the Biden administration might benefit the park, which is the most-visited in the nation.
Here’s a link to the full Department of the Interior National Parks and Public Land Legacy Restoration Fund Fund release. Here are the Foothills Parkway and Sugarlands maintenance yard project data sheets.
Babies born today may be unable to procreate without medical technology
The Guardian: Interview of Shanna Swan. 'Most couples may have to use assisted reproduction by 2045'
In her new book,“Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race,” Shanna H Swan, professor of environmental medicine and public health at Mount Sinai School of Medicine in New York City, provides more evidence how the wide use of plastics and other materials containing hormone-mimicking chemicals interfere with fertility and fecundity.
She advises how one may at least reduce exposure to these substances, to some degree, by making informed purchase decisions, such as avoiding processed food.
Knowledge particularly important for pregnant women!

Frauenhofer tandem photovoltaic solar cell achieves record efficiency
The rainbow colors show the diffraction of sunlight by a mirror with a nanostructured grating, which was applied to the back of the silicon subcell. The sun’s spectrum is thus captured even better in the silicon bottom cell. © Fraunhofer ISE / Photo: Michael SchachtnerFraunhofer Institute for Solar Energy Systems: Tandem Photovoltaics Enables New Heights in Solar Cell Efficiencies – 35.9 % for III-V//Silicon Solar Cell
The photovoltaic (PV) solar panels most commonly used for commercial applications today have an efficiency in the range of 16 to 22 percent. On the lower side of this range, one finds less-expensive panels, mostly made with poly-crystalline solar cells, while monocrystalline cells dominate the upper side.
The highest-efficiency panel presently on the market is SunPower’s A-Series residential panel, with a claimed 22.8 percent efficiency in converting photons to electrons under standard conditions. That's up just slightly by 0.73 percent from five years ago. Although many other manufacturers have caught up to offer panels rated at more than 21 percent, development progress of silicon-based monocrystalline PV toward the theoretical limit of around 30 percent has slowed to a crawl.
Over the same period, newer technologies for multijunction PV cells with thin subcell layers of gallium-arsenide and similar semiconductors, grown on top of silicon or perovskite crystalline materials, has been progressing rapidly and may be capable of exceeding 50 percent efficiency in the future. Lab results still require years of research and manufacturing development before panels come to market. Initially their high price will limit them to market niches where low-weight and small-surface per Watt will justify the cost, such as for aerospace applications or covering electric vehicle surfaces. The following links provide a good overview of such technologies and discuss their longer-term outlook.

Manhattan Project National Historical Park Stakeholder Engagement Community Meeting
National Park Service
Manhattan Project National Historical Park (MNHP) is initiating a stakeholder process that will be used to help inform the park’s interpretive planning.
Zoom Meeting - Free and open to the public - RSVP
Interpretive themes convey park significance. Primary interpretive themes are the key ideas through which the park’s nationally significant resource values are conveyed to the public. They connect park resources to the larger ideas, meaning, and values of which they are a part. They are the building blocks—the core content—on which the interpretive program is based.
Find more details about the process, background information on the MNHP and register for the first meeting here.
The interpretive plan will provide guidance in developing future services, activities, events and exhibits in Oak Ridge, at the other MNHP locations, and through media outreach.

Smokies rangers and Gatlinburg cops are cracking down on litter sources
Written by Thomas Fraser
Put a lid on it: Rangers, cops targeting unsecured garbage loads to reduce roadside litter
Great Smoky Mountains National Park rangers and the Gatlinburg Police Department made 37 traffic stops targeting insufficiently contained garbage during an enforcement campaign on the Spur on March 28 and March 29.
Unsecured trash and debris blowing from vehicles is a major source of litter along the Spur, which is used by 10 million vehicles per year and is the most heavily traveled — and heavily littered — roadway in the national park.
Rangers and police officers issued 25 verbal warnings and 13 citations during the anti-litter patrols, according to a press release from the national park.
Officials said garbage hauled from rental properties and homes often blows out of trucks and other vehicles and is a major source of litter along the busy road, which runs five miles between Pigeon Forge and Gatlinburg.
“With increasing visitation trends and more use of park roads for business and recreation, we need everyone to do their part to keep our roads litter free,” Great Smoky Mountains National Park Superintendent Cassius Cash said in a park press release announcing the targeted patrols. “To protect our scenic values and wildlife, it is vital that we prevent trash from ever being discarded in a national park.”
Law enforcement ensured the motorists hauling trash "were complying with Tennessee State Code 39-14-507, which states that any motor vehicle that transports litter, or any material likely to be blown off, is required to have the material either in an enclosed space or fully covered by a tarp," according to the park service.
The amount of litter that has accompanied increased visitation is not just a national park concern.
“The city of Gatlinburg is very concerned about the litter issues in the area and is willing to work with the national park and coordinate efforts, such as this targeted enforcement event,” said Gatlinburg City Manager Cindy Cameron Ogle in the combined release. “Together we can all make a difference to help keep our area beautiful for everyone to enjoy.”
Rangers and Gatlinburg police plan more such litter enforcement patrols throughout the year.
