Question:

Why does the statement predict that half the land will return to preconstruction conditions while the other
half of the land will not?
– Half the land has already been developed; half has not.
– Half the land is already being used for heavy industry so it will not be affected.
– Any land that is not directly under the pipeline will naturally return to its previous state,
-Half the land is under water, meaning that the environmental impact will be lessened.
