Howard Energy Partners (HEP) has closed the acquisition of a 120-mile, bi-directional Texas ethylene pipeline from EPIC Midstream Holdings on Jan. 8, the companies announced.

Howard purchased the EPIC Olefins, a line along stretching northeast along the South Texas coastline, connecting ethylene production facilities in Gregory to storage tanks in Markham. The pipeline has a design capacity of 7.8 million pounds per day.

The companies did not release a transaction value in their announcements. Howard said in its announcement that the company had recorded more than $1.1 billion in M&A deals over the past 12 months.

The closure of the deal with HEP followed the Jan. 6 announcement that EPIC had entered a $2.2 billion deal with Phillips 66 (PSX). Phillips 66 bought a long-haul NGL pipeline connecting the Permian Basin with facilities near Corpus Christi and further east.

HEP said the pipeline strengthens its Gulf Coast position and offers synergies with the firm’s Corpus Christi Javelina Plant, a gas processing plant that extracts olefins, hydrogen and NGLs from streams produced by local refineries.

“This acquisition aligns with our long-term strategy of building a diversified midstream company through organic growth and acquisitions, anchored by long-term contracts,” said Mike Howard, HEP’s chairman and CEO.

EPIC, backed by Ares Management Corp., said the deal showcased the company’s ability to build necessary infrastructure for the region.

“The transaction completes the successful development, operation and divestiture of critical midstream infrastructure along the Texas Gulf Coast,” said Brian Freed, EPIC CEO.

For the transaction, TPH&Co. served as the financial adviser and Kirkland & Ellis LLP served as legal adviser to EPIC. Bracewell LLP and Sidley Austin LLP served as legal advisers to HEP.
