The newly developed finds of natural gas in eastern Ohio, Pennsylvania and West Virginia could be making their way through northwest Ohio, if a proposed pipeline project is approved.  The Marcellus and Utica Shale regions are producing huge amounts of natural gas that could lower costs for consumers.   The Energy Transfer Rover Pipeline Company has filed a preliminary application with the Federal Energy Regulatory Commission for that pipeline, which would take natural gas from the fields of eastern Ohio, to the markets of the Midwest and Canada.            The application states the natural gas would run 380 miles, in a pipeline about 36 to 42 inches in diameter; with 5 compression stations.    A proposal would have that pipeline run through the mid-section of HenryCounty, and link with the current Panhandle Eastern pipeline company.
