The US Fish and Wildlife Service (USFWS) is postponing a decision on the listing of the coaster brook trout (Salvelinus fontinalis) as endangered, under the federal Endangered Species Act. The agency is expecting to reach a final decision by April 15, 2009.

In February, 2006, the Sierra Club and Huron Mountain Club (HMC) filed a joint petition with the USFWS to seek protection for the coaster, under the Endangered Species Act.

The USFWS cited the recent completion of a genetics study as the reason for the delay. Kim Scribner, professor at Michigan State University’s (MSU) Department of Fisheries and Wildlife, co-authored the study with other researchers from MSU and Michigan Technological University.

Jessica Hogrefe, biologist from the USFWS’s Division of Endangered Species, said that the new genetics information is “important to consider” and that preparing for a decision on the coaster is “a high priority.”

According to the Michigan Department of Natural Resources (DNR), Isle Royale National Park provides habitat for two, distinct, strains of coasters, Tobin Harbor and Siskiwit. The DNR raises and stocks these strains, as well as the Nipigon strain. Efforts have been made, recently, to reintroduce coasters into the Mosquito, Seven Mile and Hurricane Rivers at Pictured Rocks National Lakeshore. According to the DNR, the coasters, once abundant in Lake Superior tributaries and along the coast, faced a rapid decline as a result of overlogging in the 19th century, overfishing and introduction of the sea lamprey, in the 1950s. The introduction of non-native fish species, such as Pacific salmon also contributed to the decline.

Kennecott/Rio Tinto’s metallic sulfide mine project, on the Yellow Dog Plains, threatens the last remaining, naturally reproducing, population of coasters on the southern shore of Lake Superior. Coaster reproduction is dependent upon stable water temperatures produced by groundwater upwelling and is also affected by increased stream sedimentation. Fish populations are also affected by acid mine drainage and increased levels of toxic heavy metals. Kennecott plans to release 184,000,000 gallons of treated wastewater into groundwater adjacent to the Salmon Trout if it receives an Underground Injection Control permit (UIC) from the Environmental Protection Agency (EPA).

Kennecott has already contributed to soil erosion into the Salmon Trout River. In April 2005, a culvert that Kennecott designed and the Michigan Department of Environmental Quality approved, failed, dumping an estimated 98 tons of sediment into a branch of the Salmon Trout River.

Kennecott, and the Michigan Department of Environmental Quality, both neglected to consider the effects of blasting on the coaster population. As a result of fish studies showing the effects of detonating explosives nearby, Alaska now has laws protecting fish from the effects of underground blasting. According to the Alaska Department of Fish and Game, blasting “within, beneath or adjacent” to a “fish-bearing waterbody” can damage fish eggs and traumatize or kill fish, causing damage to scales and internal organs, primarily the swim bladder.

The Michigan Chapter of Trout Unlimited (MCTU) has, repeatedly, expressed concern for the coaster’s safety.

On April 10, 2007, Patrick Kochanny, MCTU Chairman, issued a press release stating that “Trout Unlimited and the Michigan Council strongly oppose this project, and believe that it is in the best interest of the State of Michigan and the Salmon Trout River to deny Kennecott’s application at this time….We are seriously concerned that analysis and review of the permit application may not have been conducted properly.”

Kochanny said this position was made at a March 30, 2007 meeting, following an extensive review of Kennecott’s mining application by “outside experts” and commented that “there is no room for error” when considering projected impacts to the Salmon-Trout River spawning grounds.

Hogrefe emphasized that the agency is still accepting information up until April 15 and the sooner they receive information, the better.

The USFWS has found itself involved in another facet of Kennecott/Rio Tinto’s mine plan. In September 2008, the agency requested the EPA to determine whether Kennecott’s mine plan would affect the endangered Kirtland’s warbler and the threatened Canada lynx. The EPA will also have to consider the threatened gray wolf. The USFWS noted that the warbler was found, near the mine project area, and that the region hosts habitat that could contain the Canada lynx. Because the EPA is mandated only to consider federal law in its actions it cannot consider potential impacts to the coaster until the species is listed under federal jurisdiction.

“The EPA was expected to issue a draft decision on Kennecott-Rio Tinto’s injection permit in December 2008. However, further information was required from the company, delaying a decision until at least late January 2009. If the coaster is listed, as endangered, following approval of the company’s permit, the EPA would have to reconsider its decision.”
