CREDIT FACILITY [Abstract]
CREDIT FACILITY	CREDIT FACILITY Our 364-day revolving credit facility dated July 15, 2010, has a borrowing capacity of up to $30.0 million, of which up to $10.0 million may be available for letters of credit (2010 Credit Facility). On July 14, 2011, we amended our 2010 Credit Facility to extend the maturity date to July 12, 2012. As of September 30, 2011, we had outstanding borrowings of $10.5 million and availability of $19.5 million for borrowings under the 2010 Credit Facility. Interest on borrowings under the 2010 Credit Facility is based upon, at our option, either an alternative base rate or a LIBOR-based rate, which was 2.0% as of September 30, 2011. The carrying amount of the 2010 Credit Facility approximated its fair value as of September 30, 2011. The terms of the 2010 Credit Facility require NuStar Energy to maintain, as of the end of any four consecutive fiscal quarters, a consolidated debt coverage ratio not to exceed 5.0-to-1.0. On March 7, 2011, we amended the 2010 Credit Facility to exclude NuStar Energy's unused proceeds from the Gulf Opportunity Zone bond issuances from its total indebtedness in the calculation of the consolidated debt coverage ratio. As of September 30, 2011, NuStar Energy's consolidated debt coverage ratio was 4.5x. We are also required to receive cash distributions of at least $35.0 million in respect of our ownership interests in NuStar Energy for the preceding four fiscal quarters ending on the last day of each fiscal quarter. Our management believes that we are in compliance with the covenants of the 2010 Credit Facility as of September 30, 2011.
