From The Durango Herald (Jonathan Romeo):
Sunnyside Gold Corp. is refusing to carry out work ordered by the Environmental Protection Agency as part of the Superfund cleanup of mines around Silverton.
“Enough is enough,” Kevin Roach, with Sunnyside Gold, wrote in an email to The Durango Herald. “EPA has a clear conflict of interest and has wrongfully targeted SGC (Sunnyside Gold Corp.) … (and) SGC will no longer be a pawn in this never-ending science project.”
In June, the EPA ordered Sunnyside Gold to install five groundwater wells and two meteorological stations at mining sites around the headwaters of the Animas River as part of the investigation into the Bonita Peak Mining District Superfund site…
Sunnyside Gold has denied any responsibility but has been willing to work with the EPA in limited ways during the past three years. On Tuesday, however, Roach sent a letter to EPA staff saying Sunnyside Gold “declines to undertake the work,” arguing the company no longer has any liability for mining pollution issues in the Animas River watershed.
Peterson said Wednesday morning that EPA has not yet received the complete letter from Sunnyside Gold…
In 1996, Sunnyside Gold entered an agreement with the state of Colorado to install three plugs to stem the flow of acid drainage out of the American Tunnel, which served as the transportation route for ore, as well as mine runoff, from the Sunnyside Mine to facilities at Gladstone, north of Silverton.
By 2001, however, it was thought the water had backed up and reached capacity within the Sunnyside Mine network. Now, several researchers and experts familiar with the basin believe water from the Sunnyside Mine pool is spilling into adjacent mines, like the Gold King.
Sunnyside Gold, which was purchased by international mining conglomerate Kinross Gold Corp. in 2003, has adamantly denied that its mine pool is the cause of discharge from other mines, saying there is no factual evidence for the assertion.
Much of the work EPA ordered Sunnyside to do, however, seeks to gain more insight into the issue. EPA, too, intends to drill into the American Tunnel this month to better understand groundwater conditions in the area.
Earlier this year, Sunnyside Gold called for the EPA to be recused from leading the Superfund cleanup, arguing it is a conflict of interest for the agency to do so after it caused the blowout at the Gold King Mine in August 2015.
EPA’s Peterson said at the time the agency “will continue to require the company to take actions to ensure that financial responsibility for cleanup is not shifted to taxpayers.”
