MDU Resources builds and repairs the infrastructure our nation needs — the roads, the power lines, the electrical wiring and appliances, the building foundations. And MDU Resources supplies the energy and fuel our nation needs — building a strong America. In doing so, MDU Resources cannot overlook its responsibility to the environment, the communities we serve and our stakeholders. Through established operational practices and by leading or participating in a number of programs, MDU Resources helps ensure a viable environment. These practices include minimizing waste and maximizing resources, supporting environmental laws and regulations that are based on sound science and cost-effective technology and complying with or exceeding all applicable environmental laws, regulations and permit requirements.
