Planning & Routing

 

2012100495082832

For new pipeline construction projects, our goal is to design projects that minimize impacts to people and the environment. Input from landowners, communities and regulatory agencies is critical for pipeline planners to achieve this goal.

Williams sites pipeline corridors within or adjacent to existing utility corridors, when practical, to minimize environmental disturbances.  During the analysis of potential pipeline routes, extra effort is taken to identify sensitive areas of ecological or historic significance. Teams of field scientists, archaeologists and biologists conduct detailed environmental surveys and evaluations of potential study corridors; searching for threatened or endangered species; sensitive wildlife and vegetation habitats; wetlands and water bodies; and areas of archaeological significance. It is critical for project planners to have accurate, current information on the proposed pipeline route so that they can make sound, appropriate routing and construction recommendations.

The location of proposed pipeline facilities associated with the Northeast Supply Enhancement project would be collocated with existing pipeline corridors for nearly the entire route. A complete and thorough environmental analysis of the route will be conducted as part of the FERC application process.

Field Surveys

a

Field surveys are critical for gathering information that will be used to determine the best possible pipeline route. These surveys can be divided into the following categories:

Engineering Survey

Engineering surveys are how we take relatively large-scale, accurate measurements of the earth’s surface. We do this in order to establish marks to instruments to take measurements related to terrain and topography. The only evidence that a civil survey has taken place are the small wooden stakes placed in the ground to identify specific geographical survey points, such as wetland or property boundaries.

Environmental Survey

Environmental surveys are performed to map and catalogue existing environmental conditions. They are critical to provide a comprehensive view of natural resources, so that we can fully understand potential environmental issues within the project area.

Cultural Resource Survey

Cultural Resource surveys are a means to identify and gather information on a property’s architectural, historical, and archaeological resources. Cultural resources are evidence of past human activity. A qualified cultural resources expert will begin by researching the area, followed by a thorough field examination to assess the project area’s physical condition as well as to determine whether there are any archaeological sites visible on the ground surface.
