How to Identify Pipelines and Pipeline Markers
The Department of Transportation requires the use of markers to indicate the location of underground pipelines. These markers provide an indication of their location and product, along with contact information of the company that operates the pipeline. Pipeline markers are generally colored yellow, red, or black. Pipeline markers are used to alert anyone who might be working near the pipeline.
A pipeline Right-of-Way refers to a strip of land usually about 25 to 100 feet wide running along pipelines, which enable workers to gain access to the pipeline for inspection, maintenance, testing or emergency situations. Right-of-Ways also maintain an unobstructed view for frequent aerial surveillance, as well as identify an area that restricts certain activities to protect landowners, the community, and the pipeline itself.
Before working in the vicinity of a suspected pipeline you are required by law to notify the One Call service for your state. By using this service you will ensure that no damage is done to underground pipelines or equipment. The One Call organization will notify the owner of any potential pipelines in the area. It is preferred that the One Call service be contacted three days prior to any excavation work; however, the law requires 48 hours advance notice prior to excavation.
