From the Associated Press via Tucson.com:
Arizona Rep. Raul Grijalva is pushing to make a temporary ban on the filing of new mining claims in the Grand Canyon region permanent.
He’ll be joined Saturday by tribal leaders at the Grand Canyon to talk about legislation he plans to introduce next week.
The Obama administration put about 1,562 square miles (4,045 square kilometers) outside the boundaries of the national park off-limits to new hard rock mining claims until 2032.
Grijalva wants to make it permanent…
Grijalva says he’ll introduce the Grand Canyon Centennial Protection Act on Tuesday when the park celebrates its 100th anniversary.
