Natural Gas Expansion Projects

Service Point Audit

Montana-Dakota Utilities Co. will be visiting every service point within our 5 state service area. MDU has hired Suburban Consulting Engineering, Inc. (SCE) to perform this audit.

You will be able to recognize SCE employees by the personal protective equipment (high visibility vests and clothing) uniforms with the MDU logo; as well as their SCE name badges. SCE employees will be driving vehicles labeled with both MDU and SCE logos. They will be carrying handheld tablet computers as well as GPS units to complete their work for this audit.

Always allow safe and easy access to your gas and electric meter by keeping the area in front of and around your meter clear at all times. We need at least two feet of clearance around the meter to provide visibility and access for routine work and also in case of any emergency.

This service point audit project will be conducted throughout the MDU service territory. Weather permitting, the project will run in all months of the years 2018 to 2024. Below is a list of locations and estimated timeframes for the current year.

The intent of the Service Point Audit is to collect data on our existing natural gas distribution system. In addition to collecting data, SCE employees will also be capturing a GPS point at each service point location. The data collected will provide value as we strive to continue to provide safe and reliable service.

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, but will not need to enter the customer’s home. 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.
