Enterprise and Navigator Gas to Build Ethylene Export Terminal

HOUSTON & LONDON–(BUSINESS WIRE)–Enterprise Products Partners L.P. (NYSE: EPD) and Navigator Holdings
Ltd. (NYSE: NVGS) announced today that they have entered into a 50/50
joint venture to build a new ethylene export facility along the U.S.
Gulf Coast that will have the capacity to export approximately 1 million
tons of ethylene per year. Refrigerated storage for 30,000 tons of
ethylene will be constructed on-site and will provide the capability to
load ethylene at rates of 1,000 tons per hour. The facilities are
expected to be in service by the first quarter of 2020. The project is
supported by long-term contracts with anchor customers that include U.S.
ethylene producer Flint Hills Resources and a major Japanese trading
company.

“This new ethylene export terminal will support the growing production
of ethylene on the U.S. Gulf Coast by providing access to international
markets,” said A.J. “Jim” Teague, chief executive officer of
Enterprise’s general partner. “By 2021, the petrochemical industry is
expected to expand aggregate ethylene production capacity in Texas and
Louisiana by nearly 50 percent to approximately 90 billion pounds per
year. The resulting rapid growth in the supply of U.S. ethylene,
combined with increased demand from international markets, like Asia,
creates an ideal scenario in which markets abroad are able to diversify
their supply by accessing cost-advantaged feedstocks made possible by
the shale revolution in the United States. This export terminal will
also offer diversification opportunities for domestic petrochemical
producers who will not have to rely solely on the export market for
derivatives like polyethylene. We are very pleased to work with
Navigator Gas in efforts to commercialize an industry-leading ethylene
marine export terminal that offers unsurpassed connectivity to ethylene
producers and pipeline and storage infrastructure.”

David Butters, chief executive officer of Navigator Gas, commented, “The
strong, broad interest shown by prospective terminal customers during
the initial marketing phase has reinforced our conviction on the
critical need for an ethylene export terminal. It is clear that domestic
producers value the opportunity to access global markets and
international consumers consider the U.S. as a reliable and affordable
source of ethylene to fuel their petrochemical manufacturing in Europe
and the Far East. We are delighted to work with Enterprise on this
project that promises to meet the needs of our customers and enables us
to provide the seaborne transportation of the ethylene from producer to
customer.”

Enterprise is also developing a high-capacity ethylene salt dome storage
facility at its complex in Mont Belvieu, Texas. This storage facility
will have a capacity of approximately 600 million pounds with an
injection/withdrawal rate of 420,000 pounds per hour. The storage
facility is expected to begin service in the first quarter of 2019 and
will be designed to enable connections to the eight ethylene pipelines
within a half-mile of the Enterprise ethylene storage system. In
addition, Enterprise is building a new ethylene pipeline from Mont
Belvieu to Bayport, Texas, which is scheduled to begin service in 2020.

The location and final investment decisions for the terminal are subject
to reaching acceptable arrangements with local taxing authorities.
