The US Fish & Wildlife Service has decided to list the Diamond Darter, a fish that is only found in the Elk River, as endangered. A news release from FWS is found here. The following is an excellent summary of the facts surrounding the listing, from Jason Bostic of the WV Coal Assn.
In
the July 26, 2012 the F&WS proposed listing the diamond darter under the
ESA. Concurrent with its proposed classification as an endangered
species, the F&WS proposed to designate 28 miles of the lower Elk River in
West Virginia (from the Confluence of King Shoals Run near the Wallback
Wildlife Management Area to near Knollwood Drive in Charleston) as “critical
habitat” for the species. This section of the Elk River contains
the only known remaining populations of diamond darters in the country.
F&WS also proposed to classify 95 miles of the Green River in Kentucky as
critical habitat since diamond darters historically inhabited the area,
although none exist there today.
F&WS
has NOT made a decision regarding critical habitat designation in the notice
that will be published tomorrow. The decision regarding critical habitat
will come later, as will any proposed protection measures.
In
the July 2012 Federal Register notice announcing the proposed listing and
critical habitat designation, F&WS identified several factors that may
jeopardize the continued existence of the diamond darter, including water
quality impacts associated with coal mining activities undertaken on
tributaries to the Elk River. F&WS claims that sedimentation, metals
and increases in downstream conductivity threaten the existence of other
sensitive fish species and therefore pose a threat to the diamond darter.
The agency’s conclusions regarding conductance and fish impacts is largely
based on studies undertaken by the agency on the Kentucky Arrow Darter in the
Cumberland River Basin.
Although
mining activities generally do not directly exist within the 28-mile range of
proposed critical habitat designation area, concerns related to the alternation
of that critical habitat area could be applied to any proposed / current mining
activity on any of the Elk River’s tributaries. The terms of the ESA that
require federal agencies to ensure that permitted activities will not
jeopardize the continued existence of an endangered species and/or its habitat
would apply directly to Clean Water Act (CWA) Section 404 permits issued by the
U.S. Army Corps of Engineers and indirectly to the issuance of permits
by the state under the Surface Mining Control & Reclamation Act, and
potentially to state issued Clean Water Act Section 402 NPDES permits.
