Energy Transfer Partners Responds to FERC
DALLAS, October 9, 2007 — Energy Transfer Partners, L.P. (NYSE:ETP or the Partnership)
confirmed that the Partnership today delivered its response to the Federal Energy Regulatory
Commission (FERC) “Order to Show Cause” filed on July 26, 2007.
In reaffirming that the Company’s business transactions were conducted in a lawful and
responsible manner, ETP’s response decisively refutes FERC’s claims and shows that FERC’s positions
are fundamentally flawed.
“As we stated at the time the Order was received, we believe FERC’s allegations are entirely
unfounded. Our detailed response is an important first step in setting the record straight and
making the facts clear,” said Jerry Langdon, Energy Transfer Partners, Chief Administrative and
Compliance Officer. “We look forward to an objective review by FERC and believe the evidence will
show that our conduct was appropriate.”
ETP expects its complete response to the FERC to be made available in the eLibrary on the
FERC’s website, www.ferc.gov, docket number IN06-3-002. The Partnership will provide a summary of
their response on ETP’s website, www.energytransfer.com. ETP will respond separately to the
Commodity Futures Trading Commission (CFTC) on or before October 15th.
