Construction of the new water plant at the city’s water intake on the Clinch River could start in May and be complete in December 2022, according to a proposed schedule presented to Oak Ridge City Council.

The Council on Monday will consider a construction administration contract for the new water plant, which would be south of Bethel Valley Road. It would be able to treat 16 million gallons of water per day.

If approved Monday, the professional engineering services agreement would be with Jacobs Engineering Group Inc. of Knoxville. The contract would be valued at up to about $1.88 million. It would be for construction administration and observation of the construction of the new water treatment plant and a main transmission line.

Approval of the agreement with Jacobs Engineering on Monday could be contingent upon the city’s ability to use Drinking Water State Revolving Funding, which is pending approval, according to the resolution to be considered by Council.

ORAU receives National Science Foundation grant to study greenhouse gases in Arctic

The National Science Foundation Office of Polar Programs has awarded ORAU a collaborative research grant to study greenhouse gas emissions in the Arctic. The award is valued at $581,829.

The grant will be used to study local and regional emissions of isotopes of methane and carbon dioxide. Methane and carbon dioxide are two greenhouse gases. Greenhouse gases can help raise the Earth’s temperature, changing the climate and causing other significant changes. (Isotopes are different forms of an element that have equal numbers of protons but different numbers of neutrons in their nuclei.)

In a press release, ORAU said carbon stored in permafrost is increasingly vulnerable to thaw and decomposition by microbes as northern latitudes such as the Arctic continue to warm.

“This decomposition has the potential to lead to large increases in methane and carbon dioxide emissions, both important greenhouse gases,” ORAU said. “Accurate and reliable forecasts of greenhouse gas emissions are critical for the improvement of global models that predict changes to temperature and sea level.”

The Tennessee Valley Authority is asking for public comment about a proposal to build one or more small or advanced nuclear reactors in west Oak Ridge.

The reactors would be on the Clinch River Nuclear Site, near the Clinch River and south of Heritage Center (the former K-25 site) in Roane County.

The reactors could be advanced or small modular nuclear reactors. They would have a maximum total electrical output of 800 megawatts. They would be smaller than traditional nuclear power plants, and they would produce less power.

Oak Ridge Today has previously reported that the reactors could provide enough electricity to power several cities the size of Oak Ridge

The rebuilding of a large high-voltage transmission tower in Oak Ridge was completed Sunday, and South Illinois Avenue re-opened to traffic at about midnight.

The 155-foot steel lattice tower that had to be replaced was knocked over when a pickup truck crashed into it at about 4:15 p.m. Friday. The tower, which is at Union Valley Road, carries high-voltage Tennessee Valley Authority transmission lines and city transmission and distribution lines.

The four-lane road, the main connection between Oak Ridge and Knox County, was closed for about two days after the crash while crews removed and replaced the damaged transmission tower.

TVA said the crash also caused damage to three smaller structures, and they were repaired.

South Illinois Avenue is expected to re-open by midnight near the University of Tennessee Arboretum after being closed for more than two days because a large high-voltage transmission tower was knocked over near the road in a crash on Friday. The road re-opening is expected to occur before the Monday morning commute.

Power is still out for a small southeast portion of the city near the crash site, including the University of Tennessee Arboretum, the City of Oak Ridge said Sunday evening.

The single-vehicle crash into the Tennessee Valley Authority steel lattice transmission tower was reported at Union Valley Road at about 4:15 p.m. Friday. That section of the four-lane road, also known as State Route 62 and Pellissippi Parkway, has been closed since shortly after the crash. The road is the main connection between Oak Ridge, Knox County, and Knoxville.

TVA and the Oak Ridge Electric Department worked over the weekend to replace the damaged transmission tower, which carries TVA and Oak Ridge power lines. The repair crews had help from the Oak Ridge Police Department and Oak Ridge Public Works Department. It was a complex emergency repair, the City of Oak Ridge said.

The City of Oak Ridge has published photos of the work to replace the high-voltage steel lattice transmission tower knocked over in a single-vehicle crash at Union Valley Road and South Illinois Avenue on Friday.

The city said the Tennessee Valley Authority and Oak Ridge Electric Department crews are working together, with help from the Oak Ridge Police Department and Public Works Department, to “maintain a safe work environment for a very complex emergency repair.

“Crews are working to have South Illinois Avenue at Union Valley Road open as soon as possible,” the city said.

On Sunday, TVA said the repair work could be complete in time to re-open South Illinois Avenue, a four-lane roadway that connects Oak Ridge to Knox County, for the Monday morning commute. That’s assuming there are no delays due to weather or drilling problems.

Work to repair the damage to a Tennessee Valley Authority transmission tower knocked over in a crash on Friday could be complete in time to open South Illinois Avenue (State Route 62) in time for the Monday morning commute, a spokesperson said Sunday.

However, the schedule could be affected by weather and any potential drilling delays.

TVA spokesperson Scott Brooks said heavy equipment, materials, and workers, as well as safety and engineering plans, are required to replace the large high-voltage steel lattice tower that was knocked over by a pickup truck Friday afternoon. The safety and engineering were completed Friday evening, Brooks said.

“The heavy equipment, materials, and manpower needed to perform the work are either on site or en route,” he said. “We currently expect the work to be completed in time for Highway 62 to be open for the Monday morning commute. Risks to that schedule are weather and potential drilling delays due to the topography (i.e. rock).”

Crews were repairing the damage to the Tennessee Valley Authority power distribution system on Saturday after a pickup truck crashed into a large high-voltage steel lattice transmission tower on Friday, knocking it down and causing widespread electrical outages.

All four lanes of South Illinois Avenue (State Route 62) in Oak Ridge remain closed between Lafayette Drive/Scarboro Road and Bethel Valley Road while the repairs are being made. It’s not clear how long the work might take. The road remains closed because of heavy equipment, low hanging lines, and the safety of work crews, the City of Oak Ridge said Saturday.

Power to the University of Tennessee Arboretum remained out Saturday evening, the city said.

The steel lattice tower that was damaged Friday appeared to have been removed by Saturday evening, or it was no longer leaning near the roadway the way it had been Friday.

The crash was reported at Union Valley Road and South Illinois Avenue, near the UT Arboretum, at about 4:15 p.m. Friday. Three people were injured, and charges are pending against the driver.

Power was restored to all of Oak Ridge except for the University of Tennessee Arboretum after a crash knocked down a high-voltage transmission tower Friday afternoon, the city said Friday night.

The single-vehicle crash caused the tower to fall over and created widespread power outages. Many residents reported having power restored within about one to three hours, while it seemed to take longer to restore power in the southeast section of the city, closer to the crash site.

In its last update, posted at 10:10 p.m., the City of Oak Ridge said the Arboretum will be without power through Saturday.
