Which of the following statements about backfilling is true?

Restoring the area to its original condition, including the replacement of topsoil, is essential for several reasons. First, it ensures that the landscape remains stable and allows for the natural flow of water, reducing erosion and settling issues. Additionally, replacing topsoil facilitates the growth of vegetation, which can help stabilize the soil and protect the buried infrastructure from surface impacts. This is especially important for environmental restoration and compliance with regulations that may require the rehabilitation of land after construction or maintenance activities. Maintaining the integrity of the ecosystem supports biodiversity and minimizes the disturbance caused by the backfilling process. Proper restoration practices contribute to the overall longevity and performance of the pipeline as well as the surrounding environment.
