In 2017, North American energy infrastructure company Williams Transco proposed a 23.4-mile, 26 inch diameter pipeline as an expansion to its current subsea (below seafloor) framework that delivers natural gas to New York City and surrounding areas. This study delves into the environmental significance of the Northeast Supply Enhancement Pipeline, ascertaining that despite its projected distribution of 400 million cubic feet of natural gas per day to residents, construction will cause too much disturbance to 14,000 acres of marine habitat across the Lower Bay of New York’s harbor. This potential disturbance is supported by peer-reviewed scientific studies and literature on the structure and use of pipelines, as well as Williams Transco’s safety records. While receiving acceptable review from the Federal Energy Regulatory Commission (FERC) with regards to environmental impact, past failures of similar projects signifies too much risk to local marine biodiversity.
