U.S. Army Corps analysis looks at Enbridge's Line 5 tunnel plan and potential environmental impacts
Building an underground tunnel for an aging Enbridge oil pipeline that stretches across a Great Lakes channel could destroy wetlands and harm bat habitats but would eliminate the chances of a boat anchor rupturing the line and causing a catastrophic spill, the U.S. Army Corps of Engineers said Friday in a long-awaited draft analysis of the proposed project's environmental impacts.
The analysis moves the corps a step closer to approving the tunnel for Line 5 in the Straits of Mackinac. The tunnel was proposed in 2018 at a cost of $500 million but has been bogged down by legal challenges. The corps fast-tracked the project in April after U.S. President Donald Trump ordered federal agencies in January to identify energy projects for expedited emergency permitting.
A final environmental assessment is expected by autumn, with a permitting decision to follow later this year. The agency initially planned to issue a permitting decision in early 2026.

With that permit in hand, Enbridge would only need permission from the Michigan Department of Environment, Great Lakes and Energy before it could begin constructing the tunnel. That's far from a given, though.
Environmentalists have been pressuring the state to deny the permit. Meanwhile, Michigan Attorney General Dana Nessel and Gov. Gretchen Whitmer are trying to win court rulings that would force Enbridge to remove the existing pipeline from the straits for good.
Construction could have major short-term, long-term impacts
The analysis notes that the tunnel would eliminate the risk of a boat anchor rupturing the pipeline and causing a spill in the straits, a key concern for environmentalists. But the construction would have sweeping effects on everything from recreation to wildlife.

Many of the impacts, such as noise, vistas marred by 121-metre cranes, construction lights degrading stargazing opportunities at Headlands International Dark Sky Park and vibrations that would disturb aquatic wildlife would end when the work is completed, the report found.

Other impacts would last longer, including the loss of wetlands and vegetation on both sides of the strait that connects Lake Huron and Lake Michigan, and the loss of nearly 300 trees that the northern long-eared bat and tricoloured bat use to roost. Grading and excavation also could disturb or destroy archaeological sites.

The tunnel-boring machine could cause vibrations that could shift the area's geology. Soil in the construction area could become contaminated and nearly 200 truck trips daily during the six-year construction period would degrade area roads, the analysis found. Gas mixing with water seeping into the tunnel could result in an explosion, but the analysis notes that Enbridge plans to install fans to properly ventilate the tunnel during excavation.
Enbridge has pledged to comply with all safety standards, replant vegetation where possible and contain erosion, the analysis noted. The company also has said it would try to limit the loudest work to daytime hours as much as possible, and offset harm to wetlands and protected species by buying credits through mitigation banks. That money can then be used to fund restoration in other areas.
'Our goal is to have the smallest possible environmental footprint,' Enbridge officials said in a statement.
The Sierra Club issued a statement Friday saying the tunnel remains 'an existential threat.'
'Chances of an oil spill in the Great Lakes — our most valuable freshwater resource — skyrockets if this tunnel is built in the Straits,' the group said.

'We can't drink oil. We can't fish or swim in oil.'
Julie Goodwin, a senior attorney with Earthjustice, an environmental law group that opposes the project, said the corps failed to consider the impacts of a spill that could still happen on either side of the straits or stopping the flow of oil through the Great Lakes.
'My key takeaways are the Army corps has put blinders are in service to Enbridge and President Trump's fossil fuel agenda,' she said.
Tunnel would protect portion of Line 5 running through straits
Enbridge has been using the Line 5 pipeline to transport crude oil and natural gas liquids between Superior, Wis., and Sarnia, Ont., since 1953. Roughly six kilometres of the pipeline runs along the bottom of the Straits of Mackinac.

Concerns about the aging pipeline rupturing and causing a potentially disastrous spill in the straits have been building over the last decade. Those fears intensified in 2018 when an anchor damaged the line.
Enbridge contends that the line remains structurally sound, but it struck a deal with then-Michigan Gov. Rick Snyder's administration in 2018 that calls for the company to replace the straits portion of the line with a new section that would be encased in a protective underground tunnel.
Enbridge and environmentalists spar in court battles
Environmentalists, Indigenous groups and Democrats have been fighting in court for years to stop the tunnel and force Enbridge to remove the existing pipeline from the straits. They've had little success so far.
A Michigan appellate court in February validated the state Public Service Commission's permits for the tunnel. Nessel sued in 2019 seeking to void the easement that allows Line 5 to run through the straits. That case is still pending. Whitmer revoked the easement in 2020, but Enbridge challenged that decision and a federal appellate court in April ruled that the case can proceed.
Another legal fight over Line 5 in Wisconsin
About 19 kilometres of Line 5 runs across the Bad River Band of Lake Superior Chippewa's reservation in northern Wisconsin. That tribe sued in 2019 to force Enbridge to remove the line from the reservation, arguing it's prone to spilling and that easements allowing it to operate on the reservation expired in 2013.

Enbridge has proposed a 66-kilometre reroute around the reservation. The tribe has filed a lawsuit seeking to void state construction permits for the project and has joined several other groups in challenging the permits through the state's contested case process.

China blasts US for its computer chip moves and for threatening student visas
TAIPEI, Taiwan (AP) — China blasted the U.S. on Monday over moves it alleged harmed Chinese interests, including issuing AI chip export control guidelines, stopping the sale of chip design software to China, and planning to revoke Chinese student visas. 'These practices seriously violate the consensus' reached during trade discussions in Geneva last month, the Commerce Ministry said in a statement. That referred to a China-U.S. joint statement in which the United States and China agreed to slash their massive recent tariffs, restarting stalled trade between the world's two biggest economies. But last month's de-escalation in President Donald Trump's trade wars did nothing to resolve underlying differences between Beijing and Washington and Monday's statement showed how easily such agreements can lead to further turbulence. The deal lasts 90 days, creating time for U.S. and Chinese negotiators to reach a more substantive agreement. But the pause also leaves tariffs higher than before Trump started ramping them up last month. And businesses and investors must contend with uncertainty about whether the truce will last. U.S. Trade Representative Jamieson Greer said the U.S. agreed to drop the 145% tax Trump imposed last month to 30%. China agreed to lower its tariff rate on U.S. goods to 10% from 125%. The Commerce Ministry said China held up its end of the deal, canceling or suspending tariffs and non-tariff measures taken against the U.S. 'reciprocal tariffs' following the agreement. 'The United States has unilaterally provoked new economic and trade frictions, exacerbating the uncertainty and instability of bilateral economic and trade relations,' while China has stood by its commitments, the statement said. It also threatened unspecified retaliation, saying China will 'continue to take resolute and forceful measures to safeguard its legitimate rights and interests.' And in response to recent comments by Trump, it said of the U.S.: 'Instead of reflecting on itself, it has turned the tables and unreasonably accused China of violating the consensus, which is seriously contrary to the facts.' Trump stirred further controversy Friday, saying he will no longer be nice with China on trade, declaring in a social media post that the country had broken an agreement with the United States. Monday Mornings The latest local business news and a lookahead to the coming week. Hours later, Trump said in the Oval Office that he will speak with Chinese President Xi Jinping and 'hopefully we'll work that out,' while still insisting China had violated the agreement. 'The bad news is that China, perhaps not surprisingly to some, HAS TOTALLY VIOLATED ITS AGREEMENT WITH US,' Trump posted. 'So much for being Mr. NICE GUY!' The Trump administration also stepped up the clash with China in other ways last week, announcing that it would start revoking visas for Chinese students studying in the U.S. U.S. campuses host more than 275,000 students from China. Both countries are in a race to develop advanced technologies such as artificial intelligence, with Washington seeking to curb China's access to the most advanced computer chips. China is also seeking to displace the U.S. as the leading power in the Asia-Pacific, including through gaining control over close U.S. partner and leading tech giant Taiwan.

Asian shares slide as Russia-Ukraine conflict, OPEC+ output plan push oil prices higher
HONG KONG (AP) — Asian shares sank on Monday and oil prices jumped as trade tensions and the Russian-Ukraine conflict ratcheted up geopolitical uncertainty. Hong Kong's Hang Seng plunged more than 2% as Beijing and Washington traded harsh words over trade. U.S. President Donald Trump's announcement that he will double tariffs on steel and aluminum to 50% layered on still more worries for investors. A report over the weekend that China's factory activity contracted in May, although the decline slowed from April as the country reached a deal with the U.S. to slash President Donald Trump's sky-high tariffs, further undermined market sentiment. Markets in mainland China were closed for a holiday. Oil prices rallied after OPEC+ decided on a modest increase in output beginning in July. It was the third monthly increase in a row. U.S. benchmark crude oil gained $1.60 to $62.39 per barrel, while Brent crude, the international standard, was up $1.41 at $64.19 per barrel. Moscow pounded Ukraine with missiles and drones just hours before a new round of direct peace talks in Istanbul and a Ukrainian drone attack destroyed more than 40 Russian planes deep in Russia's territory, Ukraine's Security Service said on Sunday. Hong Kong's Hang Seng dropped 2.2% to 22,778.45 as China and the U.S. accused each other of breaching their tariff agreement reached in Geneva last month. Tokyo's Nikkei 225 lost 1.6% to 37,356.97, while the Kospi in Seoul fell 0.4% to 2,686.17. Australia's S&P/ASX 200 retreated 0.2% to 8,416.00. On Friday, Wall Street closed its best month since 2023. The S&P 500 retreated less than 0.1% to end at 5,911.69 and the Dow industrials Jones Industrial Average edged 0.1% higher to 42,270.07. The Nasdaq composite fell 0.3% to 19,113.77. Gap weighed on the market even though the retailer reported stronger profit and revenue for the latest quarter than analysts expected. The company behind Banana Republic and Old Navy fell 20.2% after saying tariffs on imports from China and other countries could add up to $300 million to its costs this fiscal year. It has strategies set to mitigate up to half of that before it hits its profits. Hopes had largely been rising that the worst of such worries had passed, which in turn sent stocks rallying, after Trump paused his tariffs on both China and the European Union. A U.S. court then on Wednesday blocked many of Trump's sweeping tariffs. That all sent the S&P 500 in May to its first winning month in four and its best since November. But the tariffs remain in place while the White House appeals the ruling by the U.S. Court of International Trade, and the ultimate outcome is still uncertain. Friday's most influential losses came from several Big Tech stocks. Nvidia fell 2.9% to give back some of its gain from earlier in the week after it topped analysts' expectations for profit in the latest quarter. It was the single heaviest weight by far on the S&P 500. On the winning side of Wall Street was Ulta Beauty, which rose 11.8% after the retailer reported stronger sales and profit than analysts forecast. It also raised the top end of its forecasted range for revenue this fiscal year even though CEO Kecia Steelman called the operating environment 'fluid.' Costco climbed 3.1% after the retailer's results and revenue for the latest quarter edged past analysts' expectations. In the bond market, Treasury yields eased after a report showed that the measure of inflation that the Federal Reserve likes to use was slightly lower in April than economists expected. A separate report from the University of Michigan said that sentiment among U.S. consumers was better in May than economists expected. Sentiment improved in the back half of the month after Trump paused many of his tariffs on China. In currency trading early Monday, the U.S. dollar fell to 143.55 Japanese yen from 143.87 yen. The euro inched up to $1.1364 from $1.1351.
