The above ground line will be insulated, wrapped with a protective metal shield and set on above ground supports. Erosion control, clean-up and revegetation of the right-of-way follow after the line is properly tested.

Ex

During various phases of the construction operation, space must be allowed for ancillary equipment operation and for the passage of vehicles. tremes of terrain may require even more right-of-way in specific areas to permit orderly construction.

The above description greatly oversimplifies the intricate and massive operations necessary, but provides perhaps a better understanding of the work to be done. The same work, the same care and concern for human safety and environmental damage must be made on either route. The necessary right-of-way width to permit construction of modern largediameter pipelines in accordance with environmental stipulations will vary with the type of pipeline to be constructed and the terrain to be crossed. Consequently, appropriate discretion in establishing right-of-way widths is essential.
