U.S. decides to limit leasing in Alaska petroleum reserve



JUNEAU, Alaska (AP) — The U.S. Inside Division has issued a choice to restrict roughly half the Nationwide Petroleum Reserve-Alaska to grease and gasoline leasing. The choice rolls again an strategy taken by the prior Trump administration, and it drew criticism from Alaska’s U.S. senators.

The choice signed by Laura Daniel-Davis, principal deputy assistant secretary for land and minerals administration, was dated Monday. It was launched following a latest go to to the state by Inside Secretary Deb Haaland.

The choice is according to a place the U.S. Bureau of Land Administration earlier this yr mentioned it favored. The land company falls underneath the Inside Division.

The reserve covers about 36,000 sq. miles (92,000 sq. kilometers) on Alaska’s North Slope. Below the choice, about 18,000 sq. miles (48,000 sq. kilometers) can be open to grease and gasoline leasing. That features some lands closest to present leases centered on the Higher Mooses Tooth and Bear Tooth models and the Umiat discipline, the choice states.

The plan would forestall oil and gasoline growth in areas thought of essential for delicate hen populations and the Teshekpuk and Western Arctic caribou herds, the choice states. New infrastructure can be prohibited on about 13,000 sq. miles (34,000 sq. kilometers), it states.

Plans superior through the Trump administration would have allowed for oil and gasoline leasing on about 29,000 sq. miles (75,000 sq. kilometers).

Alaska U.S. Sens. Lisa Murkowski and Dan Sullivan, each Republicans, criticized Monday’s resolution as shortsighted.

“It’s merely surprising that the Biden administration can have a look at the world and determine that Alaska is the place ‘maintain it within the floor’ ought to apply,” Murkowski mentioned in an announcement.

President Joe Biden firstly of his time period final yr directed officers to overview and reply to company actions underneath the prior administration that have been deemed in battle with insurance policies Biden set out across the surroundings, public well being and local weather change. The choice is an extension of that course of.

The Bureau of Land Administration mentioned the brand new resolution requires administration in step with plans adopted through the Obama administration, whereas “together with sure extra protecting lease stipulations and working procedures for threatened and endangered species” from the Trump-era plan.

Some conservation teams mentioned they view the brand new resolution as constructive however need extra motion.

“World occasions have predictably led to business lobbyists and the lawmakers they bankroll calling for brand spanking new home oil and gasoline leasing and manufacturing, particularly in Arctic Alaska, and within the identify of ‘power safety,’” Kristen Miller, conservation director with the Alaska Wilderness League, mentioned in an announcement. “In actuality, the reply to power safety doesn’t lie beneath the thawing Arctic permafrost however in accelerating the shift to scrub, renewable sources of energy technology.”

BLM plan increases management of Dalton Highway corridor


Public comment and protest ends on Tuesday for a major draft policy document that could guide the management of 13.3 million acres of federally managed public land in Interior and Northern Alaska.

According to the Bureau of Land Management, the document responds to “significant resource changes that have occurred in the Central Yukon Planning Area in recent decades.”

Alaska's Pristine Waterways Are Turning a Shocking Orange


Some of Alaska’s clear, icy blue waterways are turning a startling rust orange – so intense it’s visible from Earth’s orbit.

“The stained rivers are so big we can see them from space,” says University of California (UC) Davis environmental toxicologist Brett Poulin. “These have to be stained a lot to pick them up from space.”

After first noticing the problem in 2018 from river banks and fly-overs, National Park Service ecologist Jon O’Donnell, Poulin and their colleagues used satellite imagery and public reports to identify over 75 remote streams recently tainted this unusual orange color, across almost 1,000 kilometers (1,610 miles) of Alaska’s Brooks Range.

“There are certain sites that look almost like a milky orange juice,” describes O’Donnell. “Those orange streams can be problematic both in terms of being toxic but might also prevent migration of fish to spawning areas.”

Samples from some of these waterways collected between June and September 2022 contained high concentrations of iron and other toxic metals, including zinc, copper, nickel, and lead, when compared to nearby healthy streams. In some cases, these pollutants ramped up the water’s acidity from the usual pH of 8 to 2.3.

The results look similar to acidic mining runoff, Poulin says, yet there are no mines anywhere near these locations.

Instead, by examining satellite imagery from 1985 to 2022, O’Donnell, Poulin and their colleagues determined this strange phenomenon has only been occurring during the last decade, and it coincides with warmer weather and increased snowfall.

“Our working hypothesis is that the thawing of permafrost soil is allowing water to infiltrate deeper and interact with minerals that have been locked away for thousands of years,” explains Poulin.

The Arctic is warming about four times faster than the rest of our planet. That extra heat melts frozen ground, increases microbial activity, and causes ‘shrubification’ – with those new roots further disturbing the soil. Together these processes are exposing the previously protected minerals to weathering and displacing them into watersheds.

Climate change and associated permafrost thaw appear to be the primary drivers of stream impairment,” the researchers conclude. “Stream discoloration was associated with dramatic declines in macroinvertebrate diversity and fish abundance.”

This change in water chemistry due to acid rock drainage threatens not only wildlife but local people who rely on these streams for drinking water and subsistence fishing.

O’Donnell and the team are continuing their investigation in the hopes of understanding the broader ecological impacts for the region and working out when and where the toxic orange taint will strike again.

“There’s a lot of implications,” explains O’Donnell. “As the climate continues to warm, we would expect permafrost to continue to thaw and so wherever there are these types of minerals, there’s potential for streams to be turning orange and becoming degraded in terms of water quality.”
