The New Year brings a chorus of familiar concerns about the risks of building a 21-foot diameter tunnel under the Straits of Mackinac for oil and gas pipelines.
It has been just over a month since the Michigan Public Service Commission ruled Enbridge Energy could install a new 30-inch diameter pipeline segment in its Great Lakes Tunnel project. But local residents said the decision puts communities and the environment at risk of spills. Enbridge said it would deactivate existing dual pipelines once the new line is installed.
Sean McBrearty, with the advocacy group Oil and Water Don't Mix, said continuing the project risks adverse outcomes.
"Anything short of a shutdown is a grave threat to our environment, tourism, fishing, shipping and Great Lakes' way of life," McBrearty contended.
Enbridge Energy said the Great Lakes Tunnel would keep energy flowing safely to Michiganders and minimize spill risks. McBrearty disagreed, noting the 2010 pipeline rupture was, he said, among the largest inland oil spills in U.S. history.
Oil and Water Don't Mix is planning a "Day of Updates, Education and Action" Jan. 18 in East Lansing.
The Public Service Commission released a statement, saying, "Other modes of transporting Line 5's products -- such as by truck, rail, oil tanker or barges -- likely would increase environmental impairment," including spill risks.
Beth Wallace, Great Lakes freshwater campaign manager for the National Wildlife Federation, said there are plenty of independent reports pointing to alternative options.
"Enbridge's bid or effort to operate this pipeline until failure not only risks critical rights to people, but also important critical habitat to endangered and threatened species across the region," Wallace asserted.
Line 5 transports light crude oil and natural gas liquids, including propane used for home heating in Michigan. Its average capacity is 540,000 barrels per day.

The most current study from the Environmental Protection Agency estimated more than 143 million Americans are at risk of drinking water tainted with PFAS chemicals, including in Texas.
Water utility companies across the country tested their drinking water for 29 different PFAS compounds. They are known as "forever chemicals," because they do not break down easily in the environment or the body.
Neil Carman, clean air program director of the Lone Star Chapter of the Sierra Club, said the man-made chemicals are found in everyday products.
"Nonstick pans like Teflon, also stain-resistant fabrics, like Gore-Tex and waterproof clothing," Carman outlined. "The biggest source is probably from the firefighting foam."
He pointed out when firefighters use the foam to extinguish a fire, it is left on the ground and seeps into nearby water sources.
Some supporters of President-elect Donald Trump have said they want to revoke or weaken water standards for six PFAS chemicals. According to the Environmental Working Group, it would leave nearly 46 million Americans with no protections.
The EPA said its data is not yet complete but it has already identified PFAS contamination at almost 8,900 sites nationwide, including more than 100 in Texas. Carman noted the chemicals have been linked to multiple health problems.
"They could cause cancer, they disrupt the immune system, they could interfere with pregnancies, they can cause all kinds of health effects," Carman explained. "We're still learning about them but they're not good."
The Texas Commission on Environmental Quality is the state agency charged with PFAS enforcement. Carman added a home water filtration system is one option for curbing some toxic chemicals.

A delegation of New Mexico lawmakers is asking the federal government to quickly resolve long-standing litigation affecting water users in the Rio Grande Basin.
In a 2013 lawsuit, Texas alleged New Mexico farmers were using groundwater previously allocated to Texas. Then in 2022, the two states reached an out-of-court agreement. But the federal government objected and a subsequent U.S. Supreme Court ruling said government consent was needed first.
Andrew Mergen, visiting assistant clinical professor of environmental law at Harvard University, said a lot has changed since the original water compact was signed in 1939.
"This is, in some ways, about growth in New Mexico that has accelerated groundwater pumping in the Rio Grande," Mergen pointed out. "How are you going to manage that groundwater pumping in a way that the compact terms are met?"
New Mexico's U.S. Senators and Representatives have sent a letter to the Departments of Interior and Justice asking for resolution by year's end. Bergen believes it is unlikely but without it, the states and federal government must argue their case at a trial in federal court.
Mergen noted decades-old water allocations in the West were based on what was known at the time. Parties could only guess about population growth and could not anticipate the advent of more oil and gas drilling, increased groundwater crop irrigation and sustained periods of drought, all amid climate change.
"That's what makes this profoundly difficult," Mergen observed. "That's what the rub of this case is, that the compact was negotiated a long time ago. Things change. How do you account for change?"
The Rio Grande Basin is critical to agriculture, industry and the environment, providing irrigation water for nearly 2 million acres of crop and pasture land, supporting the outdoor recreation economy and providing habitat for fish and wildlife.

Despite some progress, Pennsylvania and other states in the Chesapeake Bay Watershed are unlikely to meet their 2025 pollution commitments to reduce nitrogen, phosphorus and sediment pollution. An assessment by the Environmental Protection Agency's Chesapeake Bay Program reveals that more than two-thirds of the Bay and its tidal rivers did not meet clean-water standards between 2020 and 2022.
Harry Campbell, science policy and advocacy director with Pennsylvania office of the Chesapeake Bay Foundation, said pollution levels vary based on land use, local economies and population, and stresses that a stronger workforce is essential for Pennsylvania to meet its goals.
"There simply are not enough scientists, engineers and planners, even in some cases, construction crews and equipment to meet the demands for conservation assistance that landowners, that farmers and communities are asking for and have resources dedicated for the implementation of those practices," he said.
Campbell noted that Gov. Josh Shapiro reaffirmed Pennsylvania's commitment to bay restoration in June. The $220 million Pennsylvania Clean Streams Fund addresses major river and stream impairments and includes a program to help farmers adopt sustainable practices. This year's state budget also allocates an additional $50 million to the fund, ensuring ongoing support for programs like the farmer-focused cost-share initiative.
Campbell said an updated Bay agreement would unify efforts toward healthy rivers, streams and a vibrant Chesapeake Bay by focusing on the performance and cumulative impact of conservation practices. New technologies help identify specific locations for these practices, optimizing their effectiveness in restoring and protecting the ecosystem.
"One of the things is something like the emerging tools that allow us to actually identify on an individual landscape where to put a conservation practice literally down to the foot, instead of five feet over there. In another place, you put that practice in this location, and it has more effectiveness," he continued.
Campbell added that governors and other leaders from the Chesapeake Bay region, will meet on December 10th. The foundation urges in-person attendance from all members, including the governor, to discuss and commit to updating the Chesapeake Watershed agreement by the end of 2025. This update is designed to address new challenges and incorporate the latest science.
