Pipeline Water Crossings

Keystone XL will cross the Missouri and Yellowstone Rivers in Montana. 

The U.S. State Department, along with a number of agencies including the Montana Department of Environmental Quality (MDEQ), conducted a comprehensive review of Keystone XL and water resources, including groundwater, surface water (e.g., rivers, streams) and water supplies. 

The U.S. State Department concluded in its final environmental analysis that building Keystone XL based on stringent U.S. regulatory guidelines and conditions “would result in a project that would have a degree of safety over any other typically constructed domestic oil pipeline system under current code.

The Pipeline Hazardous Materials Safety Administration is the regulatory body that governs protected pipeline water crossings.  Some of their requirements for safety include:

But efforts to ensure the highest levels of safety near waterways don't stop there.

The oil and natural gas industry policy takes pipeline water crossing safety for pipelines, such as Keystone XL, beyond the regulatory burden.  Examples of industry measures to heighten safety include:

As a result of these regulatory and industry-initiated measures, incidents in and around water crossings are at an all-time low, with the goal always being a perfect record of zero incidents.
