Can dirt bikes and ATVs/four-wheelers damage pipelines by driving on the rights-of-way? Is this a security risk?

As a policy, we do not approve of the use of the pipeline rights-of-way as a vehicular trail. Such vehicles can damage the earthen cover over the pipeline and in some instances may damage the pipeline itself. If such trails are to cross the pipeline rights-of-way, the trail owner should contact us to coordinate the installation of a crossing that will ensure there will be no impact to the earthen cover of the pipeline.
