The Packaging Assets are primarily located on-site at MMLP's naphthenic lubricant refinery in Smackover, Arkansas providing MMLP with the only single-site, fully-integrated lubricant refining, blending and packaging facility in the United States. The assets include a 235,000 square foot production and warehouse facility, 2.8 million gallons of bulk storage and on-site, state-of-the-art blending and packaging equipment. In addition, the Packaging Assets include a warehouse and bulk lubricant blending and storage facility in Kansas City, Kansas.
Based on current market conditions and operational estimates, MMLP estimates the acquisition of the Packaging Assets will add an incremental $11 to $13 million of cash flow in 2013. Furthermore, low-cost growth capital expenditures and efficiency improvements across our lubricants business should drive additional growth in volumes and cash flows beyond 2013.
Cardinal currently has four natural gas storage projects in operation or under development, located in the southeastern United States. Current working gas capacity totals approximately 19 billion cubic feet ("bcf"). An additional 35 bcf is expected to come on line in the summer of 2013. Including this new capacity, approximately 76% of our working gas storage capacity is under long-term contracts with an average weighted contract life of approximately 7 years.Three projects currently in development are under project financing arrangements with certain provisions that require cash flow sweeps and amortization of outstanding debt. As a result, Cardinal has not historically made distributions to its members with respect to these projects. Assuming no refinance of these Cardinal project financings, MMLP expects no material distributions from these projects in 2013 and 2014. Based on current market conditions and operational estimates, however, Cardinal intends to refinance the project finance debt into a revolving credit facility late 2013 or 2014. MMLP currently anticipates investing a total of $30 to $40 million in Cardinal for these three projects in 2013 and 2014. Assuming a Cardinal refinancing at the end of 2014, MMLP estimates total distributions from these projects of $20 to $30 million in 2015.
