Environment

A comprehensive environmental impact assessment process – conducted by the Federal Energy Regulatory Commission (FERC) and governed by the National Environmental Policy Act – has concluded in their draft report that the Midship pipeline will have no significant lasting environmental impacts, based on our planning process, mitigation plans, construction approaches, and operational management systems.

Protection Efforts


Midship will be co-located with existing pipelines for approximately 70% of its route, significantly minimizing its impacts. We are taking many other steps to reduce potential impacts, from rerouting to implementing leading construction and operation processes. Specific examples of our environmental protection efforts include the following:

  • No long-term impacts on wetlands – We have rerouted the pipeline to avoid significant lasting impacts to wetlands. The pipeline will cross under just one half an acre of wetlands.
  • No significant impacts on threatened or endangered species – In conjunction with the U.S. Fish and Wildlife Service, we conducted extensive research and surveys for potential impacts on threatened and endangered species, and the regulators have found that Midship will have no significant impacts.
  • Protecting water resources – In their draft report, FERC has determined that Midship will not have any significant lasting impacts on water resources. To help ensure this, we are using horizontal directional drilling (HDD), in environmentally sensitive areas. HDD allows us to drill underneath riverbeds and wetlands and avoid open trenching, excavation or using equipment directly in these sensitive areas to limit impacts. We are also performing baseline water quality surveys of water wells and springs in the area and will sample these water sources before and after construction in the immediate area.
  • Delivering cleaner energy – The U.S. Energy Information Administration (EIA) estimates that U.S. greenhouse gas (GHG) emissions have decreased by 14% since 2005, due in large part to the increased use of natural gas in electric power generation2. According to the EIA, the shift to natural gas in electricity generation has reduced U.S. CO2 emissions by more than 2 billion metric tons from 2005 to 20163. By delivering cleaner-burning natural gas to utilities, industry, and other end users, the Midship pipeline will support this trend of reducing GHG emissions and help reduce other air emissions associated with power generation.
  • Ongoing environmental monitoring – During construction, the pipeline will be monitored by trained environmental inspectors, who will report daily to Midship project managers and weekly to FERC. Environmental monitors will coordinate with individuals on site to identify and mitigate any potential environmental issues. During operations, the pipeline will be monitored regularly for possible environmental issues (see the discussion of pipeline safety and integrity for detail). We will also conduct periodic aerial and surface patrols utilizing specialized leak-detection equipment.
