Minnesota rule rewrite will expand mining noise and light protections around Boundary Waters

Minnesota will expand a surface mining buffer zone around the Boundary Waters Canoe Area Wilderness after determining its existing rules didn’t do enough to prevent light and noise pollution, according to a decision released Wednesday.

The announcement from the Department of Natural Resources comes after the agency was ordered by a court to re-examine regulations for nonferrous mines, or those that extract minerals other than iron, like copper and nickel.

The agency said in a 74-page decision filed in Ramsey County Court on Wednesday that it will begin rewriting its rules to expand the size of a protective minerals management corridor next to the Boundary Waters. Mining of any kind is banned in the Boundary Waters, and mining that disturbs the surface is banned in the corridor.

“It is encouraging that they [DNR] recognize the inadequacy of the rules,” said Ingrid Lyons, executive director of Northeastern Minnesotans for Wilderness (NMW), which challenged the agency’s rules.

A DNR news release also noted that the agency will ask state lawmakers to address other concerns about mine waste storage and leaching raised by the public through comments collected about its rule in 2021. The agency reviewed 4,000 messages and letters.

“We received many comments that raised questions about the State’s policy and risk tolerance around nonferrous mining,” DNR Commissioner Sarah Strommen wrote in a statement. “We believe these broader policy questions are more appropriately addressed by Minnesota’s Legislature.”

DNR’s decision stems from a 2020 lawsuit filed by NMW. The suit argued that the DNR hadn’t done enough to protect the Boundary Waters from pollution and degradation because the state’s rules didn’t cover all of the Rainy River headwaters watershed, which flows south to north, through the 1.1 million acre preserve.

Twin Metals, a company attempting to open a copper mine near Ely, Minn., intervened in the suit. Company spokeswoman Kathy Graul wrote in a statement that it was reviewing the DNR’s decision, and that the state already had “some of the most rigorous standards in the world.”

Twin Metals, a subsidiary of Chilean mining giant Antofagasta, faces major hurdles. In January, the Biden Administration imposed a 20-year ban on mineral leases on 225,000 acres of national forest land in northern Minnesota, including the company’s mine site.

Last year, the administration also canceled Twin Metal’s mineral leases. The company sued in federal court, where the case is still pending.

Graul wrote on Wednesday that “we remain committed to advancing a modern mining project that is protective of the environment and that meets or exceeds all state and federal standards.”

While the DNR is taking action based on light and noise concerns, the agency will not consider air and water issues as it re-examines its rule. In its decision, it pointed to existing Minnesota Pollution Control Agency regulations that already protect air and water quality.

“We like the destination. We’ve got some questions about how they got there,” Lyons said.

Hardrock mining of copper and nickel — which would be new to Minnesota — risks compounds in the rock interacting with air and water to create acid drainage.

NMW and Twin Metals both have 30 days to challenge the decision by asking for a contested case hearing, where parties can bring experts before a judge to analyze the details of the DNR’s decision.

Lyons said NMW is still deciding whether to pursue a hearing on the air and water issues the agency did not address.

Twin Metals did not comment on whether it would challenge the DNR’s decision.

Palestinian officials say an Israeli strike on a school-turned-shelter in northern Gaza killed 15

DEIR AL-BALAH, Gaza Strip — An Israeli strike on a school sheltering the displaced in northern Gaza on Thursday killed at least 15 people, including five children, according to Gaza’s Health Ministry.

The Israeli military said the strike targeted dozens of Hamas and Islamic Jihad militants who had gathered at the Abu Hussein school in Jabaliya, an urban refugee camp in northern Gaza where Israel has been waging a major air and ground operation for more than a week.

Fares Abu Hamza, head of the ministry’s emergency unit in northern Gaza, confirmed the toll and said dozens of people were wounded. He said the nearby Kamal Adwan Hospital was struggling to treat the casualties.

“Many women and children are in critical condition,” he said.

The Israeli military said it targeted a command center run by both militant groups inside the school. It provided a list of around a dozen names of people it identified as militants who were present when the strike was called in. It was not immediately possible to verify the names.

Israel has repeatedly struck tent camps and schools sheltering displaced people in Gaza. The Israeli military says it carries out precise strikes on militants and tries to avoid harming civilians, but its strikes often kill women and children.

Hamas-led militants triggered the war when they stormed into southern Israel on Oct. 7, 2023, killing some 1,200 people, mostly civilians, and abducting around 250 others. Some 100 captives are still inside Gaza, about a third of whom are believed to be dead.

Israel’s offensive has killed over 42,000 Palestinians, according to Gaza’s Health Ministry. It does not differentiate between civilians and combatants but says women and children make up a little more than half of the fatalities.

Como Zoo names new Amur tigers

Twin Amur tigers born at Como Zoo in August now have names — Marisa and Maks.

Two long-time volunteers who have worked with zookeepers to care for and teach the public about the zoo’s big cats came up with the names, the first to be born at the St. Paul zoo in more than 40 years.

Marisa, a name that the volunteers found to mean “spirited and tenacious,” call that a perfect reflection of her personality. The name also carries special significance for the Como Zoo community, as it honors a retired zookeeper of the same name who was instrumental in the care of large cats during her 43 years at the zoo, Como Zoo and Conservatory Director Michelle Furrer said.

The male cub has been named Maks, which is associated with meanings like “the greatest” or “strength and leadership.” The volunteers felt this was an apt description of the male cub’s confident demeanor and growing sense of leadership, Furrer said.

“Marisa and Maks aren’t just names; they’re a fun reminder of the passion and care that keep us committed to protecting wildlife every day,” Furrer said.

The newborns and their first-time mother, 7-year-old Bernadette, remain off view to allow for more bonding time, zoo officials said. The cubs’ father, 11-year-old Tsar, has been a Como resident since February 2019 and remains on view.

Fewer than 500 Amur tigers — also known as Siberian tigers — remain in the wild as they face critical threats from habitat loss, poaching and human-wildlife conflict, the zoo said.

Ash tree removals cause wood waste crisis in Minneapolis, St. Paul and across MN

Much of the wood waste in the metro area is sent to a processing site near Pig’s Eye Lake in St. Paul, where it is stored before being burned to produce energy at the St. Paul Cogeneration plant downtown.

Cogeneration provides power to about half of downtown and was originally built to manage elm-tree waste in response to Dutch elm disease. The plant burns approximately 240,000 tons of wood each year, according to Michael Auger, senior vice president of District Energy in St. Paul.

Jim Calkins, a certified landscape horticulturalist who has been involved in discussions about the problem, said he thinks using wood for energy is the most logical solution.

“The issue is, we don’t have enough facilities to be able to handle that, at least in the Twin Cities,” Calkins said. “So there has to be dollars to support transportation to get the wood to those places, or in some cases, to upgrade some of those facilities such that they are able to burn wood.”

Plans are in place to convert Koda Energy in Shakopee to burn ash wood, which could potentially handle around 40,000 tons of wood waste, but that would take around two years to establish, according to Klapperich.

In some areas of the state, cities have resorted to burning excess wood waste because they felt they had no other option. Open burning wood releases a lot of carbon into the air, Klapperich said.
