The 50-foot-wide pipeline right-of-way has one 10-inch diameter refined products pipeline crossing the Volga River in Fayette, IA. The pipeline is exposed for the entire width of the Volga River. A channel has formed beneath the pipeline, causing the pipeline to span about 12 inches off the riverbed in the middle of the river.
A 12-inch natural gas pipeline crosses Buffalo Creek in Beckham County, Oklahoma in a 16-foot wide right-of-way. The creek bed and banks are composed of clay and sand. A fallen tree in the creek pushed water to the right creating a scour area and eroding the right descending bank.
The 100-foot-wide pipeline ROW has two 8-inch crude oil pipelines that cross Platte County, Wyoming. The soil is composed of mostly sandy material. Wind erosion was blowing sand and removing cover from the pipelines, leaving the pipelines with shallow cover.
A 50-foot wide pipeline right-of-way has one 30-inch natural gas pipeline that crosses Las Huertas Creek, Arroyo Channel, in Sandoval County, New Mexico.
