3.  5 ship docks designed for Aframax tankships 80K - 120K DWT  Mooring piles with quick-release capabilities  Mooring system analysis being conducted for slightly smaller LPGCs

4.  Transfer propane/butane to/from liquefied gas carriers  Dual purpose – import and export of propane and butane based upon market demand  Annual throughput ~72,600,000 bbl

5.  Slightly smaller than AFRAMAX  Capacities up to 83,000 m 3  Fully refrigerated  Estimate 7-9 /mo  Maximum 11/ mo

6.  Sabine Pilots  Sabine Neches Navigation District (SNND)  USCG MSU

7.  No unusual challenges  LPGCs within the size range for night transit  Traffic increase within usual ranges  No differences compared to other traffic

8.  Same issues as for as LNG until get above Golden Pass  Project width 400 - 800 ft  Depth 40 ft minimum  Port Arthur Ship Canal –no developed areas

9.  West Port Arthur / City of Port Arthur  Residential/industrial at Port Neches  Residential areas at Nederland ~1.4 miles from dock  Environmental Resources  LPG operations present no new risks for those areas

10.  Modest increase in deep draft vessel traffic volume  2,800 vessel arrivals & 71,000 barge transits in 2012  20% to/beyond Sunoco  8 LPGCs/mo = 96/yr = 3.4% increase  11 LPGCs/mo = 132/yr = 4.7% increase

11.  Pilots – 29 pilots and 2 trainees – Adequate for expected levels of operations  Tugs – local fleet = 11 vessels – #1 concern overall – Fleet might have to grow to meet demand

12. Safety Risk Assessment Summary

14.  Waterways leading to the Mariner South Project LPG Terminal at Nederland, TX are suitable for marine LPG operations
