Lateral Pipeline Permitting

Location: Guthrie County, Iowa

Client: Northern Natural Gas Co.

Completion Date: December 2007

Burns & McDonnell provided environmental studies and permitting services to Northern Natural Gas Co. for construction of a proposed lateral pipeline in Guthrie County Iowa. Northern Natural Gas Co. plans to construct 22 miles of a 6-inch diameter lateral natural gas pipeline between the Ogden B mainline and a new meter station at the Hawkeye Renewable Fuel Ethanol Plant located near Menlo, Iowa.

Burns & McDonnell mobilized to the site on short notice to conduct a biological survey of a proposed 100-foot wide pipeline right-of-way corridor for wetlands and threatened and endangered species. Wetland features were delineated in accordance with U.S. Army Corps of Engineers protocol. Wetland and water body boundaries were logged with a GPS receiver for data reduction using ESRI-GIS software. Cultural resource surveys and reporting was performed by teaming with a local university familiar with Iowa's state requirements for conducting phase one archeological surveys. The phase one archeology report was then reviewed by a Burns & McDonnell senior archeologist to ensure the survey met client and Iowa State Historic Preservation Officer requirements.

Burns & McDonnell worked with the client to reduce permanent impacts from pipeline construction at wetland and water body crossings to allow construction activities to be permitted under wetland nationwide permit 12 without the need for mitigation. Constructing the lateral pipeline will provide natural gas to an ethanol fuel production plant, supporting the development of alternative and renewable energy resources.
