The proposed Pebble Mine in southwest Alaska will require a number of major infrastructure projects to support the operation. The projects are among the details revealed when the U.S. Army Corps of Engineers made the company's permit application public. "We are proposing a natural gas pipeline from the Kenai Peninsula across Cook Inlet and then under Iliamna Lake in order to get natural gas to our mine site in order to run our electrical generation,” said Pebble Limited Partnership spokesperson Mike Heatwole.
