Trouble For SemGroup Energy Partners

Another SemGroup subsidiary may be going out of business.

SemGroup Energy Partners is the only publicly traded company in the SemGroup fold.  It missed a quarterly filing deadline and says troubles with its parent company may cause it to go under.

SemGroup Energy Partners does 82% of its business with SemGroup LP, and since the Tulsa company has filed for bankruptcy the partnership say it has not been able to respond to its creditors.
