Before you begin any excavation project, use your state One-Call Center. This service is available to you, free of charge, so that you can proceed safely with any digging, trenching, blasting, excavating, drilling, plowing, boring, augering and grading. Never guess where a pipeline is located.
If you ever damage or hit a Northern Natural Gas pipeline, no matter how minor the contact may seem, call Northern Natural Gas immediately so we can assess the damage. Before excavating, please call your state One Call Center.
