SGLP Files Third Quarter 2008 Form 10-Q and Enters Into Asphalt Storage Contracts and Leases Relating to its Asphalt Facilities

TULSA, Okla.--(Business Wire)--
SemGroup Energy Partners, L.P. ("SGLP") (Pink Sheets: SGLP) today announced that
it filed its Quarterly Report on Form 10-Q for the quarter ended September 30,
2008 and that it has recently completed the execution of asphalt storage
contracts or leases relating to 39 of its 46 owned asphalt facilities with
various counterparties.

Asphalt Storage Contracts and Leases

"We are very pleased to announce that we have entered into storage or lease
agreements with 11 various counterparties for our asphalt facilities. We believe
our ability to get these facilities quickly under contract highlights the
strategic location and strong industry demand for our asphalt and residual fuel
oil assets," stated Jerry Parsons, Executive Vice President - Asphalt
Operations.

SGLP will operate the facilities under the storage agreements and the contract
counterparties will operate the facilities under the lease agreements. SGLP will
receive storage fees or lease payments as appropriate from the new
counterparties and the agreements are effective between May 1st and June 1st
with terms extending primarily through December 31, 2011. The revenues that SGLP
will receive pursuant to these leases and storage agreements will be less than
the revenues received under the Terminalling and Storage Agreement with
SemGroup, L.P.

Parsons further said, "We look forward to working with our new counterparties in
these terminal facilities and are also pleased that the majority of the
operational employees at the terminals will continue to be employed by either
SGLP or by the new third-party counterparties. We continue to be in discussions
with additional counterparties on the remaining facilities not yet under
contract and are hopeful we can execute similar contracts on those locations in
the near term."

Kevin Foxx, Chief Executive Officer and President of SGLP`s general partner
added, "The asphalt contracts, in connection with our existing crude oil
storage, transportation and terminalling business further stabilize our
revenues, which we expect on a go-forward basis to be more than 95% from third
parties. We also wish to express our gratitude to our new asphalt
counterparties, existing crude oil customers and approximately 400 employees for
their continued support."

Filing of Form 10-Q

SGLP today filed its Quarterly Report on Form 10-Q for the quarter ended
September 30, 2008. As previously disclosed, SGLP`s common units were delisted
from the Nasdaq Global Market ("Nasdaq") effective at the opening of business on
February 20, 2009 due to SGLP`s failure to timely file its Quarterly Reports on
Form 10-Q for the quarters ended June 30, 2008 and September 30, 2008. SGLP`s
common units are currently traded on the Pink Sheets, which is an
over-the-counter securities market, under the symbol SGLP.PK. SGLP continues to
work to become compliant with its SEC reporting obligations and intends to
promptly seek the relisting of its common units on Nasdaq as soon as practicable
after it has become compliant with such reporting obligations. However, there
can be no assurances that SGLP will be able to relist its common units on Nasdaq
or any other national securities exchange and SGLP may face a lengthy process to
relist its common units if it is able to relist them at all.
