Mid-America Pipeline Company, LLC (MAPL) and Enterprise

Enterprise Products Partners L.P. is the second largest publicly traded, midstream energy partnership with a value of approximately $7 billion. The intermediate sectors of the energy industry downstream of oil and gas production and upstream of end user consumption are known as midstream. These sectors provide services to producers and consumers of energy. These services generally include but are not limited to natural gas gathering, processing and wholesale marketing and Natural Gas Liquids (NGLs) fractionation, transportation and storage.

Enterprise Products Operating LP is the pipeline operating company for Enterprise Products Partners LP and began operating the Mid-America Pipeline (MAPL) in 2002.

Enterprise's 12,000-mile network of NGL pipelines provides its producing and consuming customers with access to multiple markets and a diversified supply. These pipelines traverse 20 states and link the major supply and consuming regions. The Company's storage assets, which includes 56 underground storage caverns located in seven states with a net storage capacity of approximately 119 million barrels, complement its pipeline assets and provides its customers additional value-added services in the form of an assured supply of natural gas.

MAPL has three major operating systems:

  • The 2,548-mile Rocky Mountain segment transports mixed NGLs produced from more than 20 natural gas processing plants in Wyoming, Utah, Colorado and New Mexico to existing markets in the Gulf Coast and Midwest.

  • The 2,740-mile Conway North segment links the large NGLs market hub in Conway, Kansas with petrochemical and refining customers and propane markets in the upper Midwest.
  • The 1,938-mile Conway South system connects the Conway hub with refineries in Kansas and transports mixed NGLs from Conway and processing plants in the Mid-Continent to the Seminole pipeline in West Texas.

During the last three years, the transportation volume on the Mid-America system has averaged 640 million barrels per day. Enterprise owns a 98 percent interest in the Mid-America pipeline system.

Enterprise was recognized in 2003 as having the lowest incident rate for the number of hours worked among the largest companies by the Gas Processors Association. This is the third consecutive year the company has won this award, and the sixth time in the last eight years that Enterprise placed first in Division I category.  The culture of safety is prevalent throughout Enterprise and extends to operations of all of its assets.
