A new report finds more than half of the sewage facilities in Idaho had pollution violations in 2022.

The sixth annual analysis by the Idaho Conservation League says 57% of the state's wastewater treatment plants discharged harmful substances last year.

Will Tiedemann, conservation associate with the Idaho Conservation League, said the report focuses on facilities that had the potential to cause the most harm - such as those releasing wastewater in sensitive habitats.

He said size has had an impact on those violations in recent years.

"There's quite a few facilities that are a little smaller and they do deal with outdated equipment," said Tiedemann, "either failed, you know, or were built 20, 30, 40 years ago."

Collectively, there were 520 violations of the Clean Water Act by Idaho wastewater treatment plants in 2022. The report focuses on three facilities that accounted for a quarter of the violations in Driggs, Jerome and Kuna.

Tiedemann noted that there are some positives in this report. Facilities in 51 cities and towns reported no discharge violations.

Others made significant improvements from 2021 to 2022 - including those in Blackfoot, Marsing and Wilder.

"This isn't an insurmountable issue," said Tiedemann, "that numerous examples of facilities who have dealt with issues and have made the investments and put in the resources and the time and the hard work to address this issue. So we definitely commend those facilities."

Tiedemann said having the means to curtail violations can be a major issue, especially for smaller towns. But he said federal resources are available, including through COVID-19 relief funds.

Hoosiers could get their holiday trees from any of about 200 tree farms in the state, according to the Indiana Christmas Tree Growers Association. But some families choose artificial trees, and each choice comes with environmental consequences.

Delaney Barber, energy and climate manager for the Hoosier Environmental Council, said live trees help store carbon dioxide in the atmosphere, but when they are disposed of, that process creates carbon.

"If it's just going into a landfill, it's probably the worst," Barber said. "It's going to degrade down over time because it is biodegradable, but it will release more emissions as it degrades."

One report on the website earth.org claims real Christmas trees have an average carbon footprint of almost eight pounds of carbon dioxide if destroyed in a wood chipper after use. In a landfill, the carbon footprint increases to 35 pounds.

Barber suggested that Hoosiers take their live trees to designated drop-off sites in most cities for recycling, to create mulch or compost.

Artificial trees require minimal maintenance and can last for years. However, Barber explained, they're made from petroleum-based plastics and take hundreds of years to break down in a landfill. Where the tree is made presents more questions.

"Are you getting the fake Christmas tree from a U.S. manufacturer," she said, "or is it coming from overseas? And then, there's more transportation emissions for that."

About 80% of artificial Christmas trees are manufactured in China, with a lifespan of up to 30 years. Some companies are making them out of recycled materials, which helps reduce their carbon footprint.

Bloomington and Indianapolis are getting some international recognition for the work they're doing to help the environment. The two have been named "A List Cities" by the International Council for Local Environmental Initiatives.

Only 119 cities and counties worldwide got A List designation this year, for "bold leadership on environmental action" and transparency about their plans. The cities are on what's known as the Carbon Disclosure Project Track, making progress to curb carbon emissions.

Director of the Office of Sustainability for the City of Indianapolis, Morgan Mickelson, said one reason for the Indianapolis ranking is its efforts in tree planting.

"Trees are really important to help us lower surface temperature in our neighborhoods, also to help purify air," she explained. "We have a large effort with Keep Indianapolis Beautiful to plant trees, and we work really intentionally with KIB to ensure that we're planting trees in areas that historically have not seen as much investment in terms of tree planting."

Nonprofit Keep Indianapolis Beautiful runs programs that encourage teen and adult involvement, and partners with the city on multiple conservation projects.

Bloomington's Climate Action Plan features many carbon-cutting objectives, including boosting food markets to help grow that city's local food economy and reduce waste.

The Office of Sustainability also administers Thrive Indianapolis, the city's first sustainability and resiliency action plan.

Mickelson said since 2018, more than 31,000 trees have been planted in public spaces -- and that's just a start.

"I also want to caution everyone that the work is not done," she warned. "We're in the climate crisis. I would just encourage everyone to take the time to reflect on all the hard work that is being done, but to also not forget that we have a lot more work ahead."

This is the sixth time Indianapolis has received an 'A' rating.

A Virginia group is working out ways to reforest former mines across Appalachia.

The state has several hundred thousand acres of mine land, which was being handled under the Virginia Department of Energy's Abandoned Mine Land Economic Revitalization Program. But other groups feel reforesting mine lands can play a role in reducing global carbon levels.

Diana Dombrowski, carbon research fellow at Appalachian Voices, said this is the kind of project the carbon-offset market can invest in.

"They're interested in projects that not only are maybe more local, to where they're based, but also have an environmental justice perspective," Dombrowski explained. "When it comes to the work of reforesting mine land, we're aware of a need in central Appalachia."

The process begins with reclaiming the mine land, which could cost from $7.5 billion to almost $10 billion. But the carbon offset market made $277 billion last year, so it sounds possible. There also are other options available. The Bipartisan Infrastructure Law provides almost $113 billion, appropriated for Virginia's Abandoned Mine Reclamation Fund.

Reforesting former mining areas can help Virginia achieve its climate goals. The projects can add to resilience against storms for communities, and help keep air and soil healthy.

Dombrowski noted other challenges could come up, such as how to identify the best sites for reforesting projects.

"Designing a project that can plan for the most carbon sequestration," Dombrowski suggested. "Where you pick the best land versus a project where you are maybe running over an average, that maybe people will see in the public at large."

Since the work is in the earliest phases, other challenges could arise. Dombrowski pointed out one priority is to focus on environmental justice. She added if any projects turn a profit, the funds will be reinvested into the workforce or materials to keep the work going.
