BILLINGS, Mont. -- Construction of the Keystone XL pipeline is going forward, cutting a path through northeast Montana, but climate action groups and tribes say along with environmental concerns, the pipeline poses a health threat with the COVID-19 pandemic.

Gov. Steve Bullock is allowing work to go ahead because infrastructure workers are considered essential. Under pipeline owner TC Energy's plans to bring hundreds of workers across the border, said Summer Nelson, director of the Sierra Club Montana chapter, there's a clear threat of spreading the virus.

"Health care is essential, getting food to people is essential," she said, "but constructing a tar-sands pipeline that isn't even fully approved or certain to ever be completed is absolutely not essential."

Groups opposed to the pipeline are awaiting decisions on multiple lawsuits that could block the project. TC Energy's efforts to bring Alberta tar sands to global markets got a boost in March with $1 billion from the province, and pipeline supporters have said it will bring jobs to the region.

The pipeline would carry up to 830 million barrels of oil a day from Canada to the Gulf of Mexico. Nelson said emissions from the carbon-intensive tar sands would be equal to 51 coal-fired power plants.

Indigenous people have a number of health concerns, as well. Angeline Cheek, a member of the Fort Peck Indian Reservation, said tar sand sinks when it hits water, making it hard to clean up. She added that her home especially is vulnerable to the coronavirus threat.

"With the KXL coming through, it puts the indigenous communities at risk," she said. "All we have on the reservation are three ventilators."

Cheek said Fork Peck elders are planning a prayer and protest, using social-distancing guidelines, near the pipeline construction site this week. She said folks should be more considerate about their treatment of the environment, especially with the threat from climate change.

"We don't have control over the environment or what happens to the world," she said, "and to us, that means that we're only guests here, and that we need to be more respectful and mindful of the decisions that we make."

Southwestern Pennsylvania is a major U.S. hotspot for gas extraction through fracking, but new polling reveals overwhelming public support for tighter industry oversight.

More than four in ten Pennsylvanians told pollsters they'd support an outright ban on fracking.

Sean O'Leary, senior researcher at the Ohio River Valley Institute, said the poll was conducted to assess voters' attitudes toward the fracking industry.

Multiple questions were asked about what could be done to minimize or reduce some of the impacts of fracking.

"And what we found was that, across the board, across a variety of different measures," said O'Leary, "more than 90% of all Pennsylvanians supported increased efforts in those regards."

O'Leary points to a recent University of Pittsburgh study that found significant health risks associated with living near fracking sites.

The poll shows 86% of Pennsylvanians are broadly concerned about water, and 82% about air pollution.

Nearly eight in ten say they worry about the effects of pollution on their family's and community's health. And more than four in ten believe fracking has negative effects on air and water quality.

O'Leary said voters in Pennsylvania are still generally supportive of the natural gas industry.

But he said he believes that's the result of what he called "a widespread misunderstanding" that fracking is vital to Pennsylvania's economy.

He contended fracking has led to a net loss of jobs and population in some counties, causing significant economic loss to these regions.

"The other thing that I think a lot of people are not aware of is that in Pennsylvania, in just the last four years, the fracking industry has laid off 40% of its workforce," said O'Leary. "Four out of every 10 workers in fracking have lost their jobs."

He said early industry-funded studies predicted fracking would create around 250,000 jobs in Pennsylvania.

But recent data show it's been fewer than 20,000, or less than one-percent of the state's total workforce.

A recent study from the Sierra Club found people in Brookfield, Connecticut, could face severe effects from a proposed compressor station expansion.

The pipeline's owners conducted their own health study but the Sierra Club said it was flawed and did not account for several factors. The new study showed people nearby will face higher fine particulate matter emissions and many other noxious gases, like carbon monoxide.

Kerry Swift, a longtime Brookfield resident, said it began with one compressor station back in 2006.

"The next year they put in for two and now they want four," Swift explained. "There's these three huge interstate pipelines that are aging and they're putting more and more compressor stations on them; putting more and more gas through them, which they weren't built for."

A major issue Swift and other residents have with the expansion is the emissions will vent 1,900 feet from Whisconier Middle School. The town's elected officials and residents want the state's Department of Energy and Environmental Protection to deny the project's air permits. Along with Brookfield, the village of Athens, New York recently passed a resolution urging Gov. Kathy Hochul to similarly deny air permits for the expansion.

Another concern about the expansion is Connecticut is supposed to cut greenhouse gas emissions 45% by 2030.

Nick Katkevich, campaign organizing strategist for the Sierra Club, noted an electric compressor station could be better for the environment but said blowdowns would still be a problem.

"Basically what's happening is the company needs to release pressure on the pipeline so they'll do it at the compressor facility and basically just shooting huge amounts of fracked gas into the air," Katkevich explained.

The companies have said it would be too expensive to convert the compressor station to electricity. Katkevich added along with committing to air monitoring in Brookfield, the state's energy department should meet with people in town before approving expansion permits. However, the department has declined the invitation for two years.

New York State authorized utilities to develop thermal energy network pilot programs to further its decarbonization goals. Thermal energy networks use non-emitting energy sources like geothermal boreholes or waste-heat, to heat and cool buildings. Eleven pilot projects stem from commitments made in the 2022 Utility Thermal Energy Network and Jobs Act.

Allison Considine, senior campaigns and communications manager for New York, Building Decarbonization Coalition, said college campuses with these systems are seeing a striking number of benefits.

"Using a thermal energy network, especially with geothermal is about six times more efficient than using a traditional gas furnace or oil furnace," she explained.

She added that buildings must go electric if New York will reach its decarbonization goals. Though the state's Building Code Council included the All-Electric Buildings Act in its 2025 draft code update, neighborhoods still face challenges in implementing thermal energy networks. Considine said barriers in state law prevent utilities from connecting multiple independently owned buildings to a thermal energy network.

The pilot programs could reach active construction by 2026 or 2027. They'll be online for five years so the respective utility agencies can gather data about their efficacy. But, to ensure the transition to cleaner fuels, Considine said certain laws have to be changed to move New York away from fossil fuel energy systems.

"And there's a provision on the books, we kind of call it New York's pro-gas mandate, which requires utilities to continue delivering gas service if a customer demands it, even if there is a less polluting, more affordable alternative for that customer," she added.

The New York HEAT Act would end this rule and allow the state to move toward a more energy-efficient future. The bill gives the state's Public Service Commission authority to align utility companies with the state's climate laws. It also phases out gas line extension allowances, which reduced the use of gas in the state.
