Basin Electric Power Cooperative – September 13, 2013
Construction began Sept. 6 on a natural gas pipeline from Dakota Gasification Company’s Great Plains Synfuels Plant to Basin Electric’s Antelope Valley Station. Both facilities are located near Beulah, ND.
The pipeline project is in response to new rules from the U.S. Environmental Protection Agency (EPA) to address changes in the Clean Air Act emissions requirements for electric utilities and other industries during periods of startup, shutdown or malfunction.
As a result of these rules, Antelope Valley will convert from fuel oil to natural gas for use during these periods and the pipeline will supply the natural gas.
Plans to construct the 3.5-mile, 10.75-inch diameter steel pipeline were presented to the North Dakota Public Service Commission (PSC) on June 13 in Stanton, ND, and approved by the PSC July 10.
The pipeline route will tap into the Synfuels Plant’s metering station located southwest of the plant. The route parallels the Synfuels Plant on the south and west, entering the Antelope Valley plant site from the north.
Project Manager Tyler Schilke, Basin Electric mechanical engineer III, said construction on the pipeline will be completed in two phases.
“The underground pipeline installation will be complete in the middle of October 2013. Then the above-ground construction, consisting primarily of site grading, station piping and equipment installation, will be complete in February 2014,” Schilke said.
Operation is scheduled to begin May 2014 after the maintenance outage is complete at Antelope Valley Unit 1. The pipeline will be owned and operated by Dakota Gas.
