Expansion Projects

NYMarc Project

NYMarc Brochure

Dramatic increases of natural gas supplies in New York and Pennsylvania are expected over the next 15 years driven by production from the prolific Marcellus Shale deposits.  Iroquois’ NYMarc project is designed to bring these supplies to the Hudson River Valley, Long Island, New York City and New England.  As proposed, NYMarc would receive gas from both the Tennessee Gas Pipeline in Wantage Township, New Jersey and the Millennium Pipeline in Minisink, New York. To minimize environmental and visual impacts, the pipeline would cross beneath the Hudson River between the towns of Lloyd and Poughkeepsie via an approximate 1-mile horizontal directional drill before continuing on to an interconnect with the existing Iroquois mainline in Pleasant Valley, New York.
