About Bluestone Gathering

A wholly-owned subsidiary of DTE Energy, the Bluestone Gathering System delivers Marcellus Shale gas in Pennsylvania and New York to Millennium Pipeline and Tennessee Pipeline.

Project Benefits

  • Bluestone provides market access to local Marcellus Shale gas, thereby increasing reliability and optionality to gas consumers.
  • By providing an outlet for gas produced from properties held by local landowners, landowners with shale gas on their property will be able to realize the financial benefits of royalties.
  • As a high pressure gathering system, the Bluestone Gathering System has the ability to move a larger volume of gas through a single line as compared to lower pressure systems resulting in a lesser overall impact to both landowners and the environment.

Key Facts

  • The 44.5 mile Bluestone Pipeline and Gathering system ranges in size from 16 to 20 inches in diameter with smaller in-field pipeline connections to gas well pads along the gathering system route.
  • Capacity is expected to be 975 MMcf/day to both Millennium Pipeline and Tennessee Gas Pipeline with the capability of future expansions as required to meet additional needs.
