Enterprise’s butane isomerization business reported gross operating margin of $27 million in the third quarter of 2013 compared to $26 million in the third quarter of 2012 primarily due to the addition of a new deisobutanizer facility at our Mont Belvieu complex in March 2013. Butane isomerization volumes during the third quarter of 2013 were 100 MBPD compared to 104 MBPD in the third quarter of 2012.

The partnership’s propylene business reported gross operating margin of $28 million for the third quarter of 2013 compared to $55 million for the third quarter of 2012 due to lower sales margins and higher operating costs. Propylene fractionation volumes were 74 MBPD for the third quarter of 2013 compared to 73 MBPD in the third quarter of 2012. Related propylene pipeline volumes were 123 MBPD for the third quarter of 2013 compared to 119 MBPD for the third quarter of 2012.

Enterprise’s refined products pipelines and related services business reported gross operating margin of $3 million for the third quarter of 2013 compared to $7 million for the third quarter of 2012. This lower gross operating margin was largely due to a $15 million decrease in gross operating margin from the TE Products Pipeline. Certain sections of our TE Products Pipeline had lower volumes and incurred higher pipeline integrity expenses in preparation for use as integral segments of the Appalachia to Texas Ethane Express (ATEX) pipeline, which is expected to begin commercial operations in the first quarter of 2014. Refined products marketing and products terminals reported an aggregate increase in gross operating margin of $10 million for the third quarter of 2013 compared to the third quarter of last year. Total pipeline volumes for this business were 568 MBPD for the third quarter of 2013 compared to 571 MBPD for the third quarter of 2012.
