Midwest Fuels Basis Hit by Explorer Restart Uncertainty

   SECAUCUS, NJ (DTN) -- Midwest fuel prices fell broadly Wednesday (8/19) as 
market participants remained in the dark over the timeline for the resumption 
of Explorer Pipeline's fire-damaged farm tanks, allowing futures markets to 
dictate play.

   Lack of operational clarity left physical traders hesitant to push 
differentials higher despite underlying supply uncertainty following Monday's 
fire that damaged three tanks at Explorer's Glenpool facility in Oklahoma.

   In Chicago cash trading Wednesday, the basis for ultra-low sulfur diesel 
(ULSD) was heard traded at a 21cts discount to September NYMEX ULSD, widening 
by 6cts.

   The ULSD basis for the Buckeye Complex and Wolverine pipelines rose 3cts 
each to trade at a 18cts discount to September NYMEX ULSD futures contract.

   In gasoline, CBOB basis at Chicago, Buckey and Wolverine widened 4cts each 
to a discount of 7cts versus the NYMEX RBOB futures contract for September 
delivery.

   The NYMEX ULSD for September delivery climbed 2.2cts to close at $4.4523 
gallon on Wednesday. NYMEX RBOB for September dropped 4.66cts, to settle at 
$3.2551 gallon.

   Fuel traders reported growing discontent over the inability to price the 
potential supply tightness resulting from the outage to the 1,830-mile Explorer 
Pipeline system, which transports refined petroleum products northward from the 
Gulf Coast into the Midwest.

   "The market is receiving zero concrete information or news out of Explorer 
Pipeline or Glenpool," a Midwest fuels trader told DTN. "While an operational 
impact is inevitable, nobody knows what the scope or duration of that impact 
will be yet."

   Without clear guidance on when product flows will resume northward from PADD 
3 into PADD 2, market participants said they were leaving cash basis unanchored 
and allowing underlying NYMEX futures movements to drive prompt valuations.

   In an email to DTN Wednesday, a spokesperson reiterated Explorer Pipeline's 
comments from Tuesday that "the timeline of resuming full operations north and 
south of the facility is under review." It stated previously that local 
operations in Oklahoma have been paused to focus on "on-site reclamation and 
remediation process".
