D-J Basin Lateral Pipeline is a 125-mile natural gas liquids pipeline, that will connect the Denver-Julesburg Basin in northeastern Colorado with the Overland Pass Pipeline near Weld County, Colo.

The D-J Basin Lateral Pipeline is designed to transport as much as 55,000 barrels per day of raw natural gas liquids (NGLs) from five existing natural gas processing facilities in the D-J Basin to the 760-mile Overland Pass Pipeline.

The Overland Pass Pipeline is designed to transport 110,000 barrels per day of NGLs. Additional pumping facilities could further increase the capacity to 255,000 barrels per day.

Why the Pipeline Is Needed
Due to increasing demand for NGLs, existing NGL pipeline capacity is reaching its limit as more volumes of NGLs are produced. Increasing NGL production in the Rocky Mountain region correlates with increasing natural gas development in the region.

What Are Natural Gas Liquids?
Natural gas liquids are used to produce ethane, butane and propane for home heating, indoor and outdoor cooking, motor fuels and other industrial and residential uses.

Protecting the Environment
We are committed to carefully selecting and surveying a route that protects and preserves environmental, archaeological and cultural resources. Our survey process involves consultations with state and federal agencies and the collection of data and studies of local wildlife, water and soil conditions.

Right of Way
ONEOK Partners works with landowners to negotiate easement agreements for the right of way where the pipeline will be built, operated and maintained. The typical easement is 50-feet wide, with some larger workspace easements needed during construction. Following construction, right of way will be fully restored to its previous condition.

Looking Ahead
Construction is currently under way with initial start-up scheduled in early 2009.

Pipeline Specifications
The pipeline will be 6 to 12 inches in diameter, made of high-strength steel, and coated with a protective layer to ensure pipeline integrity. The pipe will generally be buried at least three feet below the ground surface, as required by the U.S. liquids pipeline regulation Title 49 CFR Part 195.

Commitment to Safety
Safety is our highest priority. The pipeline will be designed, built and operated to meet all federal and state safety standards. Safety measures include monitoring 24 hours a day, seven days a week; safety control valves to isolate segments of the pipe; and routine inspections using sophisticated technology.
