Reviving Black Diamond’s Coal Mine in Seattle’s Green Shadow

Coal mining could be coming back in the Northwest to an old coal mine in southeast King County.

The Pacific Northwest was once a coal mining powerhouse.

In the late 1800s, The area around Oregon’s Coos Bay had over 70 coal mines. Later, Washington’s biggest coal mine in Centralia supplied the Bonneville Power Administration with electricity.

But the Coos Bay coal mines closed in the latter part of the 20th century; the Centralia Coal Mine closed in 2006. Today, both Washington and Oregon get their coal from Montana.

But that might be about to change. Coal mining could be coming back — to an old coal mine in southeast King County.

The John Henry Coal Mine, which is about 30 miles southeast of downtown Seattle, in Black Diamond, has been inactive for nearly two decades. But the Pacific Coast Coal Company has proposed reopening the mine. If permitted, the mine would produce 84,000 tons of coal every year for the next six years.

This September the federal regulator in charge of surface mining published its finding: that the proposed mine would have no significant impact on the environment. The deadline for public comment on that finding is closing Tuesday.

“It’s hard for me to see how they came to find no significant impact from blasting coal, trucking coal, and burning coal here in King County,” says Collin Jergens, with the environmental group Fuse Washington.

He’s worried about noise in an area that is much more densely populated than when the mine was last active.

The environmental assessment says any noise and vibrations are mitigated by limiting the hours of coal blasting to between 6 a.m. and 10 p.m. on weekdays.

Jergens is also worried about air quality. The coal would be shipped by truck — up to ten round trips to Seattle or Tacoma five days a week — to be burned at the Ashgrove Cement Plant in south Seattle or to be shipped by barge to the Lehigh Cement Plant in Delta, just south of Vancouver, British Columbia.

Others are concerned that phosphorus and copper could pollute nearby streams, which are home to coho salmon and cutthroat trout. And they’re worried about the impact extracting, transporting, and burning more coal could have on climate change.

The environmental assessment states that the mine would release about 170,000 million tons of carbon dioxide every year for six years, thereby increasing King County’s fossil fuel emissions by about 2 percent per year, but the “impact on climate change would be negligible and short-term.”

The agency did not respond to questions about the environmental impacts of the proposed mine.

After the public comment period closes, the agency has the option to grant a permit for the mine, modify the environmental assessment but still grant a permit or, in the event that the public comment period reveals a significant impact the agency had not considered, complete a full environmental impact statement.

This aricle is serverly lacking... HOW does one submit public comment?  Which Thursday does public comment end?  What date was this story even published? Please Eilís O’Neill KUOW/EarthFix These are obvious...I sent my Public Commnets to: Marcelo CalleManager, Program Support DivisionOffice of Surface Mining Reclamation and Enforcement1999 Broadway, Suite 3320Denver, CO 293-5035 Office(303) 293-5032 Fax He replied and said he would forward it to the project manager for whatever that is worth...
