Frequently Asked Questions
What is the Diamond Pipeline?
The Diamond Pipeline is a 20-inch crude oil pipeline that runs approximately 440 miles from Cushing, Okla. to Memphis, Tenn.
Who owns and operates the Diamond Pipeline?
Diamond Pipeline LLC is a joint venture between Houston, Texas-based Plains All American Pipeline and San Antonio, Texas-based Valero. Plains is responsible for operation of the Diamond Pipeline.
When was the pipeline be built?
Clearing and construction began in 2016. The project was completed in November 2017.
Why do we need pipelines?
Pipelines play a vital role in our daily lives. Crude oil, which is refined into the gasoline and other fuels that power our cars, boats, planes and trains, is commonly delivered via pipeline, as is the natural gas that heats our homes. Pipelines deliver fuel to generate electricity; they supply raw materials that create consumer goods; and they provide the energy that drives our industrial and manufacturing industries.
Where can I find a map of the pipeline route?
Maps of the Diamond Pipeline can be found here.
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.
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. Our design and construction methods meet or exceed the United States Department of Transportation pipeline standards. New pipe was manufactured to exceed industry standards and specifications. The pipeline was laid at an increased depth to reduce susceptibility to third-party damage.
How is the Diamond Pipeline monitored?
The Diamond Pipeline is 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 is 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.
How was the route chosen?
At the beginning of the route selection process, we took into consideration available data regarding geography; existing pipelines; county and city boundaries; population; utility corridors; watersheds; federal, state and tribal-owned land; environmentally sensitive areas; and other relevant information. We also had teams on the ground, visually inspecting the entire route, and consulted with federal and state regulatory agencies regarding preferred routes. The route was developed to minimize impact to the environment, cultural sites, and landowners during construction and operation.
What are the benefits of the Diamond Pipeline?
The pipeline provides a direct and reliable route to transport crude oil from the Plains Cushing, Okla. terminal to Valero’s Memphis Refinery, which produces gasoline, diesel and jet fuel for residents in Arkansas and several other states in the region.
How many jobs did the project create?
At the height of construction, we had more than 2,200 contractors working to construct the Diamond Pipeline. This resulted in a boost to hotel, restaurant and other hospitality and service industries for communities along the pipeline route. Once pipeline construction was completed, 15 full-time jobs were created.
What is the economic impact of the Diamond Pipeline?
The estimated cost of the pipeline is $900 million. In addition, the pipeline provides more than $11 million in annual tax revenue to communities along the pipeline route.
