TUSHKA — An Iowa man locked himself to a piece of heavy machinery Monday in an Earth Day protest against the Keystone XL pipeline.
Alec Johnson, 61, was one of four people arrested during Monday's protest in Atoka County, organizers said.
Johnson took action to defend the Red River, according to the Great Plains Tar Sands Resistance. Organizers described Johnson as a climate justice organizer from Ames, Iowa.
It is the fifth protest launched by the environmental group in an attempt to block the Keystone XL pipeline.
The protest also fell on the final day to the State Department's public comment period for the transcontinental pipeline.
“This is our environmental impact statement,” said Richard Ray Whitman, spokesman for the Great Plains Tar Sands Resistance. “We are taking a stand to protect our access to clean water.”
Pipeline opponents are concerned about the potential risks of moving diluted bitumen from Canada's oil sands across the United States, citing the recent rupture of an Exxon Mobil line in Arkansas.
