(WBI Energy) owns and operates a natural gas transmission pipeline system and associated aboveground facilities in the states of North Dakota, South Dakota, Montana, and Wyoming. WBI Energy is filing an abbreviated application with the Federal Energy Regulatory Commission (FERC or Commission) pursuant to Section 7(c) of the Natural Gas Act, as amended, and Title 18 Code of Federal Regulations (CFR), Part 157 of the Commission's regulations requesting approval to construct, install, operate, and maintain the proposed facilities described below. WBI Energy is proposing to construct, install, operate, and maintain the Valley Expansion Project (Project), which will consist of approximately 37.3 miles of 16-inch diameter natural gas pipeline from a proposed interconnect with the existing Viking Gas Transmission Company (Viking) pipeline near Felton, Minnesota (milepost [MP] 0.0) to a new electric-driven compressor station near Mapleton, North Dakota (MP 37.3) that will be tied into WBI Energy’s Line Section 24. Associated auxiliary facilities will also be constructed with the Project. The pipeline will transport natural gas with bi-directional flow capabilities and will span across the state border from Clay County, Minnesota into Cass County, North Dakota. In order to provide the volumes of natural gas requested through the open season process, WBI Energy will also replace town border stations (TBS) and construct a regulator station in Barnes, Stutsman, and Burleigh counties, North Dakota, respectively. Construction of each facility will involve a new footprint; therefore, these facilities are evaluated in this environmental report. A complete description of the Project facilities is provided in section 1.1 of Resource Report 1. Resource Report 6 describes the geologic resources crossed by the Project facilities. This report identifies potential impacts of the Project on geologic resources, geologic hazards that may potentially affect construction and operation of the facilities, and geologic hazards that may place the facilities and/or public at risk. Where appropriate, mitigation measures are described that are intended to reduce the impact of the Project on geological resources and/or reduce the impact of geological hazards on the facilities.

  • Arthur Gray Leonard (North Dakota) Edward C
    Arthur Gray Leonard (North Dakota) Edward C. Murphy (North Dakota Geological Survey) Arthur Gray Leonard was born on March 15, 1865, in Clinton, N.Y. His father was a Congregational minister, which resulted in the family moving several times while Leonard was a boy. He graduated from Salt Lake Academy in Utah and from Oberlin College in 1889. Leonard returned to Oberlin College and obtained his master’s degree in 1895. He worked on and off for the Iowa Geological Survey between 1893 and 1903. The Iowa survey provided him with valuable field experience and training that he applied later in his career. He taught geology in Western Toledo, Iowa, during the winter months of 1894–96. In 1896, he became assistant state geologist of the Iowa Geological Survey. Shortly thereafter, he went to Johns Hopkins University in Baltimore, Md., obtaining his Ph.D. in 1898. He returned to the Iowa Geological Survey as assistant state geologist and remained there until 1903, except for 1 year’s leave of absence to teach at the University of Missouri. Dr. Leonard became state geologist of North Dakota and a professor of geology at the University of North Dakota in 1903. North Dakota had become a state in 1889. The North Dakota Geological Survey was formed in 1895, and had been under the direction of two previous state geologists (Earle Babcock, 1895–1902; Frank Wilder, 1902–03) prior to Leonard. He was to hold that position until his death on December 17, 1932. Leonard’s 29-year tenure as North Dakota state geologist is the longest in state history, although Dr.

    Sandpiper Pipeline: Comparison of Environmental Effects of Reasonable Alternatives In the Matter of the Application of North Dakota Pipeline Company LLC for a Certificate of Need for the Sandpiper Pipeline Project in Minnesota Minnesota Public Utilities Commission Docket CN-13-473 Minnesota Department of Commerce Energy Environmental Review and Analysis | December 2014 Sandpiper Pipeline: Comparison of Environmental Effects of Reasonable Alternatives Abstract North Dakota Pipeline Company LLC (NDPC) is proposing to construct the Sandpiper Project, a 565 to 608-mile long pipeline and associated facilities from the Tioga, North Dakota, through Minnesota to Superior, Wisconsin. On November 8, 2013, NDPC filed two applications with the Minnesota Public Utilities Commission (Commission): the first for a Certificate of Need (CN) and the second for a pipeline route permit for the project. The CN rules at Minn. R. 7853.0130 require, in determining if a certificate of need should be granted, that consideration be paid to the “natural and socioeconomic environments compared to the effects of reasonable alternatives,” and “the effect of the proposed facility, or a suitable modification of it, upon the natural and socioeconomic environments compared to the effect of not building the facility.” For the Sandpiper Project, the Commission concluded that an environmental analysis of six system alternatives, which were identified in the Route Permit docket, and six alternatives to the proposed project identified by NDPC in its CN application would provide it with valuable information to be weighed along with other information while making its need decision. This document is intended to provide that analysis. It is intended for the use of any party who chooses to advocate for or against consideration of an alternative in the certificate of need docket.
