BILLINGS, Mont. (AP) — Pipeline spills caused by flooding and riverbed erosion dumped 2.4 million gallons of crude oil and other hazardous liquids into U.S. waterways over the past two decades, according to a new report.
The Department of Transportation report to Congress was written in response to a 2011 spill into Montana’s Yellowstone River. The spill highlighted concerns about federal pipeline rules that require lines to be buried just 4feet below riverbeds — cover that can quickly be scoured away by floodwaters. The Associated Press obtained the report before its public release.
