Indiana Utility Regulatory Commission

Indiana Utility Regulatory Commission

IURC > Pipeline Safety Division > Interstate Pipeline Construction in Indiana Interstate Pipeline Construction in Indiana

In compliance with the requirements of IC ch. 8-1-22.6, the Pipeline Safety Division of the Indiana Utility Regulatory Commission (IURC) has established this webpage to provide information about interstate pipeline construction throughout the state of Indiana.

Pipeline Construction Guidelines Law

Current Construction Projects

Below, you will find information about current construction projects in Indiana. At this time, the IURC is aware of three interstate pipeline construction projects underway in the state. These interstate pipelines fall under the jurisdiction of the Federal Energy Regulatory Commission (FERC). 

Enbridge Line 78 Project
Enbridge Energy Partners, L.P.
FERC Docket No.: There is no case docketed before FERC

In response to market demand for increased pipeline capacity, Enbridge is proposing to expand its pipeline system generally along the existing pipeline routes they have operated in Illinois and Indiana for many years. The Project involves constructing approximately 76 miles of new crude oil pipeline from Illinois to Indiana; only about 5 miles of the project will take place in Indiana. The Project will begin at Enbridge’s Flanagan Terminal near Pontiac, Ill. and travel northeast to Enbridge’s Griffith Terminal near Griffith, Ind. The diameter of the pipeline will be up to 36 inches. The Project will be constructed generally parallel to Enbridge’s existing crude oil pipeline right-of-way. Subject to other pending regulatory approvals, Enbridge anticipates construction beginning in early 2015 with the pipeline in service in the fall of 2015. Restoration will continue during the following seasons.

Enbridge 6B Project
Enbridge Energy Partners, L.P.
FERC Docket No.: There is no case docketed before FERC

Enbridge has two major projects planned in Indiana. The Line 6B 2012 Maintenance project will replace two 5-mile segments and is part of its integrity management of Line 6B. Enbridge also plans to replace the remaining 50 miles of Line 6B in Indiana as part of its Phase 2 replacement. The existing 30-inch pipeline (which will be purged and deactivated) will be replaced with 36-inch pipe so that Enbridge can maintain integrity, avoid future maintenance repair activities that would otherwise be required, and also restore the ultimate capacity of Line 6B to meet increasing demand along this pipeline route, which is largely driven by current and planned refinery upgrades and expansions in Michigan, Ohio and eastern Canada.   While the two phases of the Line 6B project were planned in steps, Enbridge is striving to acquire permits and land access throughout Indiana so the entire 65-miles in Indiana of these two projects can be completed during the same season. Subject to final approvals, the construction is scheduled to begin in late 2012 or spring of 2013. Restoration will continue during the following seasons.

Enterprise Products ATEX Pipeline Segment 3 Project
Enterprise Products Partners L.P. 
FERC Docket No.: There is no case docketed before FERC

Enterprise’s ATEX Express will consist of an underground pipeline and related facilities extending approximately 1,230 miles from Washington County, Pennsylvania to the Texas Gulf near Houston. As currently planned, ATEX Express will have the capacity to deliver 190,000 barrels of ethane per day.  Ethane is valuable to petrochemical plants as a feedstock.  The first portion of ATEX Express will involve construction of 369 miles of 20-inch pipeline from Washington County, Pennsylvania through West Virginia and Ohio, and to near the City of Seymour in Jackson County, Indiana.  In Jackson County, the new construction will join an existing pipeline extending to Texas.  Enterprise will design and construct the first portion of ATEX Express in accordance with safety standards promulgated by the Office of Pipeline Safety in the U.S. Department of Transportation, as well as pursuant to the applicable requirements of other federal and state regulatory agencies.  Enterprise also plans to construct ATEX Express parallel to existing pipeline corridors wherever possible.  Pipeline construction is scheduled to begin as early as March 2013, with preliminary clearing work scheduled for late 2012.  ATEX Express is scheduled to be in-service during the first quarter of 2014.
