Quality Control Survey

Montana-Dakota Utilities is conducting its annual quality control survey of the natural gas system to ensure public safety and the proper operation of the gas lines and meters.

The project involves a technician walking alleys, streets and highways to inspect the natural gas mains and service lines maintained by Montana-Dakota. Southern Cross Corporation has been hired to perform this survey. You will be able to recognize Southern Cross employees by the personal protective equipment (high visibility vests and clothing) with the Montana-Dakota logo. They will be driving vehicles labeled with both Montana-Dakota and Southern Cross logos.

The Southern Cross employee will require access to customer property and the gas meter. In some areas where access to the yard is not possible, the technician will utilize a laser instrument and binoculars to view the quality and condition of the meter. They will have identification and will explain their purpose for being on private property. All people working on the project will follow CDC guidelines regarding social distancing. They will not need to enter a customer’s home.
