HELENA, Mont. -

 Thirteen people were cited for trespassing at the end of a rally in Helena held in opposition of a coal development proposal in southeastern Montana.
The cited protesters staged a sit-in along the railroad tracks in Helena Sunday. Police officers stopped the sit-in after about 10 minutes and cited the protesters for trespassing on a Montana Rail Link right of way.
The demonstration targeted the proposed Otter Creek mine in southeastern Montana, which is being reviewed by the Department of Environmental Quality.
The Independent Record reported protesters cited air and water quality and a contribution to climate change as their concerns with the project. Most of the coal would be hauled by train to Pacific ports and shipped to Asia.
A University of Montana economic report estimated the mine could add $200 million annually to Montana's economy.
