SCI is conducting wetland delineations of over 1,000 miles of the Keystone Pipeline route including centerline, access roads, pump stations and contractor yards through Illinois, Missouri, North Dakota, South Dakota, Nebraska, Kansas, and Oklahoma. Hundreds of wetlands, ponds and streams have already been surveyed, and delineated using a handheld Global Positioning System (GPS) for feature mapping. SCI is also making note of the type of habitat for threatened and endangered species. Within the states of Illinois and Missouri, SCI has identified suitable habitat and evidence of species such as Eastern Massasauga rattlesnake, Indiana Bat, bald eagle, and the decurrent false aster.

The $2.1 billion TransCanada project will traverse more than 1,800 miles from an oil terminal in eastern Alberta through two other provinces and seven Plains states. The line, to be operational in 2009, will traverse Missouri from west to east, running through St. Charles County, to ConocoPhillips' Wood River Refinery in Roxana, and on to a key oil pipeline hub at Patoka, Illinois in Marion County, 85 miles east of St. Louis. The pipeline route crosses several individual property owners, including property managed by the U.S. Army Corps of Engineers, St. Louis District.
