The U.S. Army Corps of Engineers approved 60 river crossings along the proposed route of the Bakken Pipeline, which runs diagonally northwest to southeast across Iowa.
Opponents to the pipeline, Bold Iowa and Iowa Citizens for Community Improvement, plan to continue to rally in opposition. They're also training monitors to report any environmental violations or hazards.
Several lawsuits are still pending regarding the Iowa Utilities' Board approval of the use of eminent domain to condemn private Iowa land for the pipeline project. Easement agreements have been signed for 96 percent of the property needed in Iowa.
The Corps' approval outlines conservation measures Dakota Access must undertake at sites where certain bat and fish species might be affected. Dakota Access also must provide wetland mitigation when natural wetlands are disturbed and must allow American Indian tribal monitors to observe work.
The 1,168-mile crude oil pipeline crosses 19 Iowa counties from North Dakota’s Bakken oil fields to Patoka, Illinois.
