Pipeline markers can be found where a pipeline intersects a street, highway or railroad. The markers are helpful in showing the approximate location of underground pipelines. But the pipelines may not be in a straight line from marker to marker. The markers also do not indicate the depth, size or number of pipelines in the ground. Nor are pipeline markers used on every pipeline area. So, the absence of pipeline markers does not mean a gas pipeline is not present. Pipeline markers should not be used to determine where pipelines are located for excavation purposes—always call New Mexico One Call 811 before you dig.
New Mexico Gas Company suggests that you be aware of pipeline markers in your neighborhood and keep our emergency phone number handy. It is a federal crime to deface, damage, remove or destroy any pipeline marker. Please report any pipeline emergency or damage immediately by calling our emergency line at 888-NM-GAS-CO (888-664-2726).
New Mexico Gas Company pipeline markers note that the material being transported is natural gas and provide New Mexico Gas Company emergency contact information. Below are descriptions to help you recognize natural gas pipeline markers.
The two sets of pipeline makers shown are designed to meet federal requirements. The first set of markers were used by PNM and still are in use.
On PNM Pipeline Marker 1 the word “Warning,” “Caution” or “Danger” followed by “Gas.” Except for heavily developed areas, the letters must be at least 1 inch high with a ¼ inch stroke. The PNM name and 24-hour contact number (800-282-1732) are also included. The sign is 4 inches wide and 4 feet high.
PNM Marker 2 is placed directly onto streets, curbs or sidewalks where a natural gas pipeline is installed. It is 4 inches in diameter.
PNM Marker 3 placed along rights-of-way, as needed. The markers vary in size from 1 foot by 18 inches up to 2 feet by 3 feet.
In the months to come, New Mexico Gas Company will begin phasing in the following series of markers:
