The Dakota Access Pipeline is Safe, Efficient, and Environmentally Sound


rom the beginning of development, the Dakota Access Pipeline has been built to be one of the safest, most technologically advanced pipelines in the world. Dakota Access was designed with tremendous safety factors and state of the art construction techniques and redundancies, including construction and engineering technology that meet or exceed all safety and environmental regulations.

For example, the Dakota Access Pipeline utilizes Horizontal Directional Drills (HDD) for water crossings and state of the art pressure safety design factors that exceed federal requirements by more than 35 percent for road and water body crossings. The minimum installation depth of the pipeline will exceed federal regulations by nearly two feet in agricultural areas. The separation zone between the pipe and all existing infrastructure exceeds the regulatory requirements.

During construction and prior to operation, the pipeline has been and will be subjected to careful inspection and testing to verify its integrity and compliance with all regulatory standards. Once operational, the pipeline route will be patrolled and inspected by air on a weekly basis, weather permitting, to watch for abnormal conditions. It will also be continuously remotely monitored 24/7/365, with additional regular ground inspections.

Underground pipelines are the safest mode of transporting crude oil. Monitored 24/7/365, federal statistics show that underground pipelines transport crude oil more safely than rail (3.4-4.5x safer), or trucks (34x safer). The Dakota Access Pipeline can replace rail and truck transportation of crude oil with less impact to the environment and statistically greater safety.

Key Facts

  • The Dakota Access Pipeline uses construction and safety techniques that exceed federal and state laws.
  • The Dakota Access Pipeline is an entirely underground pipeline
  • The pipeline is made of heavy-walled steel pipe that’s 50% thicker than required by law.
  • Multiple studies have found that pipelines are safer than shipping crude oil by rail or trucks.
  • The Dakota Access Pipeline can eliminate 500-740 rail cars, and/or 250+ trucks needed to transport crude every day.
