You may return to normal surface uses of the land with limited restrictions. However, any digging—even for fencing, vegetation or drainage—is prohibited without first contacting the local One-Call system (simply dial 811) or a Williams representative. No trees may be planted on the right of way. This is to (a) maintain a clear aerial surveillance of the right of way, and (b) prevent tree roots from damaging the pipeline coating. For more information on these restrictions, contact a Williams representative.
