The company has an approved compressed natural gas tariff in place to provide customers with high-pressured gas service. Further, the company has partnered with local agencies on environmental programs, and is able to allow residential and commercial customers to offset their carbon emissions by supporting carbon-reduction projects at dairies and other farms. The company purchases its gas supplies primarily from the Alberta and British Columbia areas of Canada and multiple receipt points in the U.S. Rocky Mountains.
