Our expected investment is $25 million, which represents an attractive organic growth opportunity for our NGL Logistics segment. This project provides much needed incremental NGL storage capacity for the growing Marcellus/Utica production. The expansion includes new ethane storage capacity of approximately one million barrels. The expansion is expected to be in service the fourth quarter of 2013.
