Ground Truth Trekking: Expeditions to explore environmental issues.



Exploration at proposed Pebble Mine Salmon runs can be fished every year. Forests regrow on a time scale of centuries. But oil, coal, and metals are formed by geologic processes with a time scale of millions of years. These mineral resources are non-renewable. And while fish and trees are both a resource for humans and a part of the ecosystem, minerals lie deep beneath the living earth, and are important to no species but our own.

The key issues in this region are the proposed mines in Bristol Bay, and in Northwest B.C/Southeast Alaska and the proposed offshore oil drilling in Bristol Bay and off the B.C. coast. Public attention and public participation can still influence these outcomes. Projects with unacceptable negative impacts can still be stopped. Other projects can be redesigned for better accountability, better returns to local government and communities, and better envrionmental standards.

Information on this page is gleaned from a number of excellent references, listed at the end of the page.

The environmental impacts of resource extraction fall into three basic categories:

• Local footprint - the area directly destroyed by mining or drilling operations. This is a planned part of the operation, and can be many square miles for coal mines and open pit metal mines.
• Infrastructure footprint - the areas impacted by roads, powerlines, pipelines and other development required to run a mining or drilling operation. This is also planned, but can be much larger than the mine itself - particularly when you include the energy neccessary to run the operation
• Accidents - contamination of land or water by spills or leaks of toxic substances. Oil spills, acid mine drainage, heavy metal contamination, etc... These toxic substances may be present in the mined material or added in the extraction process. Mitigation measures are supposed to prevent this, but often fail. Water pollution is one of the biggest problems at mines.

Click on a location to go to its description in this page This map shows some locations of current, proposed, and historic mining and drilling operations along or near our route on the Northern Pacific and Southern Bering Sea. There are almost certainly locations missing - especially historic mines and relatively undeveloped proposals. Feel free to contact me with proposed additions.

Mining

Metal ores are often found in regions of ancient volcanic activity. This coastline is part of the Pacific Ocean's "Ring of Fire", and ores of gold, silver, and copper are common in several regions, particularly in Northwest B.C./Southeast Alaska, and in Southwest Alaska near Bristol Bay and the Alaska Peninsula. Some sites in these regions have been historic targets for mining, but remote locations and low grade ore have often prevented development. However, in the past few years, worldwide metal prices have doubled or tripled, leading to a boom in claim and exploration activity in both B.C. and Alaska.

Though the gold rush is one of the best known pieces of Alaska history, the days of grizzled old prospectors in the mountains with gold pans are long gone. Modern mines are generally very large enterprises run by multinational corporations, and extract their metals from ore in open pit or underground mines. Their local footprints can be enormous (over 20 square miles in the case of one proposal - the Pebble Mine prospect). However the infrastructure and energy needed to run these mines is even larger - often leading to more oil drilling, coal mining, or hydropower dams to power the operations. However, the biggest impact from mining operations is often not from their planned footprint and infrastructure, but from accidental spills and leaches of contaminants into nearby waters.

Mining's track record

• Mining is the most polluting industry in the country ( EPA Toxics Release Inventory).
• Major threats to water include acid mine drainage, cyanide spills, and heavy metal pollution.
• Fish are especially sensitive to heavy metals in the water (more than people).
• A recent study shows that 76% of the U.S. mines surveyed exceeded water quality standards, polluting rivers and groundwater. (Find the full report here)
• According to the Environmental Protection Agency (EPA), mine waste has contaminated more than 40 percent of the headwaters of western watersheds.

Britannia Mine discharge Acid mine drainage occurs when naturally occuring sulfides in mined rock react with air and water, forming sulfuric acid. This acid leaks into streams, lowering their pH, and making them uninhabitable by fish and other aquatic life. Sulfides (like pyrite) are often found in ores containing copper, gold and silver. Sulfides are also common in coal seams. Under natural conditions, these rocks erode very slowly, leaching only minute amounts of acid into local waters. A mine can unearth in decades as much rock as normal geologic processes would erode in a million years, allowing all the acidification to occur at once. Acid mine drainage is very difficult to prevent, and is often one of the most problematic and long-lasting environmental impacts from a mine. It has been documented at both Greens Creek and Britannia, and is a major worry for the proposed Pebble Mine.

Historic Mines

• Britannia- An abandoned copper mine on Howe Sound just north of Vancouver. One of the most notorious sites of Acid Mine Drainage and water pollution in North America.
• Kennicott - An abandoned copper mine in the Wrangell Mountains. A railroad ran down beside the Copper River to connect the mine with the port in Cordova. The railroad is abandoned, but a road still runs from Cordova to the newly-reconstructed "million dollar bridge" over the Copper River.
• Ketchikan - Early in the 20th century, there were a number of small prospecting operations here, but not much gold was ever discovered
• Lituya Bay - Early in the 20th century, gold prospectors mined the beach sands here.

Greens Creek Mine - SEACC Operating Mines

• Greens Creek - An underground mine for silver, gold, zinc and lead, on the northwest end of Admiralty Island, in Admiralty Island National Monument in Southeast Alaska. This mine opened in 1989, was placed on standby in 1993, and reopened in 1996. It's a joint venture between the Kennecott and Hecla Mining companies. Greens Creek mine is a site of Acid Mine Drainage (see Earthworks study).
• Eskay Creek - An underground gold mine in Northwestern B.C., on a tributary of the Unuk River. Part of Iskut-Stikine volcanic belt - a rich mineral area near the border with Alaska.
• Earle Creek - A gravel mine near the town of Egmont, B.C.
• Myra Falls - An underground zinc, copper, gold, and silver mine near the town of Campbell River, B.C.
• Quinsam - A coal mine on Vancouver Island near the town of Campbell River, B.C.

Abandoned Proposals

• Windy Craggy - In the 1980s, Geddes Resources put forward a propoasl to develop this mine - a large open pit copper mine in the Tatshenshini-Alsek watershed, on a peak between the two rivers. Acid mine drainage from the sulphide-rich ore would have posed an enormous threat to both rivers and the surrounding wilderness. A group known as Tatshenshini Wild formed in 1989 to fight this plan. With growing opposition to the plan, Tatshenshini Wild spearheaded a large coalition known as Tatshenshini International. At it's peak, the group comprised 50 of the top conservation organizations in North America and represented about 10 million people.
  In the end, two things stopped the mine project: strong public opposition, and the objections of the U.S. The U.S. stood little to gain from the mine, which threatened fish runs in U.S. waters, and since the only feasible port for Windy Craggy was in the U.S. at the mouth of the Alsek, the U.S. could have vetoed the project by refusing the port.
  In 1993, this wilderness was protected in the Tatshenshini-Alsek Provincial Park, creating the only large river drainage in North America that is protected from headwaters to ocean.
• Quartz Hill - This molybdenum deposit is located in Misty Fjords National Monument in Southeast Alaska. US Borax staked a claim here in 1974, and in 1980 the Alaska National Interest Lands Conservation Act created the National Monument with a hole in it, to exempt the potential mine site and its access corridor. By 1991, some disposal permits had been denied and the price of molybdenum had dropped, making the prospect no longer worthwhile. Canadian mining company Teck Cominco owns the site now, and continues to assert the mine will be developed when molybdenum prices rise enough. Prices have risen a lot in the past several years.

Proposals and Prospects
This is the category we'll be paying the most attention to. Why? These mines haven't been built - and in many cases may not be built. Public attention and public participation can still influence these outcomes - either to prevent the mines, or to demand better accountability and envrionmental standards.


proposed Pebble Mine site
Pebble Mine Project
The Pebble Mine project is a controversial proposal by Northern Dynasty Minerals to build one of the largest gold and copper mines in the world, in southwest Alaska, near Lake Iliamna. Their current proposal involves both a large open pit and an underground mine, as well as removal of the water from the headwaters of Upper Talarik Creek and the Koktuli River ( important fish habitats). The site sits at the headwaters of two major Bristol Bay drainages ( Nushagak and Kvichak), and potentially poses a large threat to the region's water and salmon. This proposal has become a major political issue in Alaska, supported by the mining industry and heavily opposed by the commercial and sport fishing industries, and many local native villages.


proposed Pebble Mine site
Northern Dynasty is continuing major exploration activities, and expects to apply for development permits no sooner than late 2008 or 2009.

American Rivers placed the Nushagak and Kvichak rivers in Bristol Bay on its list of most endangered rivers of 2006, due to the threat of this mine.

Many other mining companies have staked claims in around Pebble in the Bristol Bay watershed. If Pebble is built, the infrastructre and the precedent for regulatory approval could be the start of the Bristol Bay Mining District

Chuitna River - Cook Inlet Keeper Chuitna Coal Project
The Chuitna Coal project is a proposal by PacRim Coal to develop Alaska's largest coal strip mine 45 miles west of Anchorage in the Beluga Coal Fields, near the communities of Tyonek and Beluga on the West side of Cook Inlet.

If fully developed, the mine would strip up to a billion metric tons of coal from roughly 30 square miles of important bear, moose, wolf and fish habitat over the next 25-50 years. According to PacRim’s permit applications, the mine would also discharge an average of 7 million gallons of mine waste each day into the Chuitna River, an important salmon resource that drains to Cook Inlet. Burning coal is also a major contributor to global warming - already disproportionately affecting Alaska.

As of spring 2007, PacRim is working on applying for permits, and the final application is slated for sometime late 2007. See the official page on Chuitna from the Alaska Department of Natural Resources

American Rivers has placed Chuitna on its list of most endangered rivers of 2007, due to the threat of this coal mine.

Other Proposals

• Galore Creek - The Iskut, Unuk, and Stikine Rivers are major transboundary waterways that flow from B.C. into Southeast Alaska, and important habitats for both fish and wildlife. They're also located in the Iskut-Stikine volcanic belt, a rich source of metal deposits. Novagold has permits to build this Galore Creek Mine on the lower Stikine river, 20km from the main stem. Potentially, they could also put in a hydropower dam in Forrest Kerr Canyon on the lower Iskut, which would dewater a significant portion of the river.
• Kensington - An underground gold mine under construction near Juneau by Couer Alaska. This mine has been at the center of a major legal battle over the Clean Water Act. Kensington sought to reclassify mine tailings as "fill", in order to dispose of them in a sub-alpine lake near the mine. Under the Clean Water Act, tailings cannot be disposed of in lakes or streams. In March 2007, the US 9th Circuit Court of Appeals ruled against Kensington
• Other Iskut River Prospects - There are many potential mine sites in the Iskut and Unuk watersheds. Skyline Gold is exploring the Bronson slope deposit on the lower Iskut River, near the old Johnny Mountain and Snip Mines.
• Other Southwest Alaska Prospects (e.g. Kamishak and Bee Creek) - A number of companies have claims and prospects in Southwest Alaska outside of the immediate Pebble Mine area. Most of these are relatively early in the exploration process, and are difficult to find much information on. Two properties currently being explored by Full Metal Minerals are Kamishak, (near the town of Kakhonak, Katmai National Park, and the McNeil River state Game Refuge) and Bee Creek (near the town of Chignik on the Alakas Peninsula).

Oil and Gas - Drilling and Transport

With the exception of the Chuitna coal proposal, most mines and mine proposals in this region are seeking metals. Metals are highly recyclable goods, and could theoretically be reused many times. Oil, on the other hand is largely burned for energy - truly non-renewable in all senses of the word. Burning oil and gas is a major contributor to global warming, which is already disproportionately affecting Alaska. Most oil drilling and proposed drilling in this region is off shore - where potential impacts include seismic exploration and oil spills. Another major risk is oil spills from tanker traffic - wherever the oil is drilled.

Historic Oil Drilling

• Katalla - Near the Copper River Delta, Katalla was the site of Alaska's first oil well in 1902. Exploration also occured here in the 1980s, but the area is currently closed.
• Mt Demian - A 1920s era oil camp near Mt. Peulik on the Alaska Peninsula.

Packraft and Cook Inlet Oil Rig Active Oil Drilling

• Cook Inlet - Offshore oil drilling has been going on in Cook Inlet since the 1960s. The Cook Inlet beluga whale population is in dramatic decline - the National Marine Fisheries Service has proposed that it be listed as endangered (2007). But Cook Inlet is the most populated waterway in Alaska, with multiple industrial activities and pollution sources. It's unclear whether or how oil drilling may have played into the whales' decline.

Proposed Oil Drilling
Bristol Bay

• Bristol Bay
  In spring 2007, the federal governement lifted the moratorium on leasing in the "North Aleutian Basin" area in Bristol Bay. This area of sea floor is located in the Bering Sea, north of the Alaska Peninsula. The Bering Sea produces half of all fish caught in U.S. waters, and Bristol Bay is home to the world's largest sockeye salmon fishery. In the winter, the Bering Sea is covered with sea ice, and known for its massive winter storms, greatly increasing the risk of a potential oil spill. These winter storms have led to a number of shipwrecks on the ice-free Pacific Ocean side of the Alaska Peninsula. We currently have no technology to stop the spread of an oil spill in partially-frozen waters.
  
  Offshore oil and gas leasing in the U.S. is under control of the Minerals Management Service. Bristol Bay was under a moratorium on leasing from 1990-2003, which was extended by President Clinton to 2012. President Bush undid Clinton's order in 2007, and the Minerals Management Service is preparing to start selling leases in Bristol Bay, as well as the Chukchi and Beaufort Seas in the Arctic.


• Queen Charlotte Basin
  There has been a moratorium on offshore oil and gas drilling in B.C. since 1972. The B.C. government would like the moratoruim lifted, but needs the federal government to agree. A 2003 review of the moratorium failed to come to any conclusions, and the moratorium remained in place. In its 2007 energy plan, B.C. continues to push for oil drilling to be allowed.
  
  Queen Charlotte Basin - between the Queen Charlotte Islands (Haida Gwaii) and mainland B.C. is one of the main targets, with known oil and gas reserves. The Queen Charlotte Basin is an especially rich area for marine flora. Risks of exploration and drilling off B.C. include oil spills (very difficult to contain in windy winter months), seismic testing (likely harmful to whales), and release of pollutants into the waters through normal drilling operations.

Oil Tankers and Oil Spills

One of the major risks with oil isn't from drilling at all - it's from tanker traffic. The Exxon Valdez oil spill that devastated Prince William Sound in 1989 came from arctic oil - drilled hundreds of miles away in Prudhoe Bay. Oil tankers have been banned from the B.C. coast since 1972, but the prime minister is currently trying to lift the ban (2007) - hoping to use the B.C. coast as a port for Alberta oil.
