When will the pipeline be built?

Clearing and construction began in 2016. The project is projected to be complete in 2017.

How was the route chosen?

Route selection criteria included identifying suitable terrain and paralleling existing utility and other pipeline rights of way where possible. The route was developed to minimize the collective impact to the environment and landowners during construction and reduce potential incidents during operation.

Why do we need pipelines?

Pipelines play a vital role in our daily lives. The gasoline that powers our cars, boats, planes and trains is commonly delivered via pipeline, as is the natural gas that heats our homes. Without pipelines, most refineries in the United States would not have access to domestic crude oil and would have to rely upon foreign sources of oil. Pipelines deliver fuel to generate electricity; they supply materials that create consumer goods; and they provide the energy that drives the industrial and manufacturing industries.

How safe are crude oil pipelines?

U.S. Department of Transportation statistics show that underground pipelines are one of the safest modes of transporting crude oil.

What is Diamond Pipeline LLC doing to maximize the safety of this pipeline?

The Diamond Pipeline is a federally regulated interstate pipeline and is subject to rigorous design, construction, operation and maintenance standards. The Diamond Pipeline will exceed the United States Department of Transportation pipeline standards and will include a number of safety elements. New pipe will be manufactured to exceed industry standards and specifications. The pipeline will be laid at an increased depth to reduce susceptibility to third-party damage.

Additionally, the Diamond Pipeline will be remotely monitored 24 hours a day, seven days a week from a centralized Control Center. These employees, known as “Controllers,” have the authority to shut down the pipeline systems at any time , but they are not allowed to restart the pipeline systems until the issue has been addressed and proper authorization has been received from Operations and Control Center management. The pipeline will be monitored with regular aerial and ground surveillance patrol as well.

What is right-of-way?

Whether above or below ground, pipelines are constructed along a clear corridor of land called the right-of-way (ROW). The ROW may contain one or more pipelines or other utilities such as power lines, may vary in width, and will cross through public and private property. The ROW should be free of permanent structures and trees and be identified with a marker sign.

What do right-of-way marker signs look like?

Pipeline markers are generally yellow, black, or red and can be found along a right-of-way (ROW). Look for them near roads, railroads, bikeways, buildings, and waterways. They can be square, round, slanted, or post-like in form. Pipeline markers will give key information about the pipeline located there, such as the name of the pipeline operator, a telephone number, the product transported and the pipeline’s general location. Pipeline markers are meant only as a general guide and warning and should not be used to determine the precise location of the underground facility. Note that there could be more than one pipeline in a ROW.

Where can I find a map of the pipeline route?

What are the benefits of the Diamond Pipeline?

The Diamond Pipeline will provide Valero’s Memphis Refinery with crude oil from Cushing, Okla., which will enhance the refinery’s long-term viability for the production of gasoline, diesel and jet fuel for greater Memphis and eastern Arkansas and provide economic benefits to the areas along the route.

How many jobs will the project create?

More than 2,000 new contract construction positions have been created across Oklahoma and Arkansas. An estimated 15 permanent jobs will be created along the pipeline route once it is completed.

What is the economic impact of the Diamond Pipeline?

The estimated cost of the pipeline is $900 million. In addition, the pipeline will provide approximately $11 million in property tax revenue per year to help support communities along the pipeline route.

What kind of oil will the pipeline carry? How much will it carry?

The pipeline is designed to transport up to 200,000 barrels per day of domestic sweet crude oil.

Is Diamond Pipeline LLC connected in any way to the Plains & Eastern Clean Line power transmission project?

Diamond Pipeline LLC is not affiliated with the Plains & Eastern Clean Line power transmission project.
