Segment Reporting, Disclosure of Entity's Reportable Segments [Abstract] |
SEGMENTS | SEGMENTS Segment Descriptions - Our operations are divided into three reportable business segments, as follows:
• | our Natural Gas Gathering and Processing segment gathers, treats and processes natural gas;
• | our Natural Gas Liquids segment gathers, treats, fractionates and transports NGLs and stores, markets and distributes NGL products; and
• | our Natural Gas Pipelines segment operates regulated interstate and intrastate natural gas transmission pipelines and natural gas storage facilities.
Other and eliminations consist of corporate costs, the operating and leasing activities of our headquarters building and related parking facility and eliminations necessary to reconcile our reportable segments to our Consolidated Financial Statements.

Operating Segment Information - The following tables set forth certain selected financial information for our operating segments for the periods indicated:
