1 PIPELINE SYSTEMS (as of ) The Northeast Gas Association (NGA) has prepared this summary based on publicly-available information. NGA will strive to keep the information as updated as possible and notes that this information may change pending project developments. May not include all projects. New Market Dominion Pipeline Planned for customers in upstate NY (National Grid). Includes the addition of 2 new compressor stations along DTI s existing transmission pipeline; and increased compression at an existing station. 84 MMcf/d. Line D National Fuel Gas Supply 77,500 Dth/d. Path is Lamont to Erie, PA. New compressor station. Susquehanna West Connecticut Tennessee Gas Pipeline/Kinder Morgan Tennessee Gas Pipeline/Kinder Morgan Incremental supply to existing interconnect with National Fuel. Capacity of 145,000 Dth/d. 8.2 miles of 36 pipeline loop. Capacity of 72,100 Dth/d. Pipeline looping on TGP 200 and 300 lines. Customers are CT natural gas utilities.

2 PIPELINE SYSTEMS (as of ), page 2 Garden State Williams/Transco Designed to provide up to 180,000 dekatherms per 3 rd qtr 2017 day of natural gas service in two phases to a new (Phase 1) / delivery point with New Jersey Natural Gas in 2 nd half 2018 Burlington County, N.J. The project will include the (Phase 2) installation of a new compressor station, meter and regulating station on land located in Burlington County, N.J. It will also require modifications and the addition of compression at an existing compressor station. No expansion of the pipeline is required. Atlantic Bridge Enbridge Incremental expansion on Algonquin and Maritimes & Northeast, to serve New England and Canadian Maritimes. Proposed capacity of ~133,000 Dth/d. Valley Lateral Continent to Coast (C2C) Millennium Pipeline PNGTS The will connect Millennium s gas mainline to CPV s energy center in Wawayanda, NY, and provide access to natural gas for its new 650 MW combined-cycle electric power generating facility. C2C will access natural gas supplies from key North American natural gas basins via TransCanada Pipeline. Atlantic Canada markets can then transport on PNGTS to an interconnect with Maritimes and Northeast Pipeline at Westbrook, ME. Shippers interested in moving natural gas further south into New England can transport on PNGTS to interconnects with other NE natural gas pipelines.
