Twin Rivers Exploration seeks narrower tile buffer, expanded road access for seismic survey; supervisors pause decision

Twin Rivers Exploration asked the Wright County Board of Supervisors on April 21 to amend a county road-use permit so the company can complete seismic surveys aimed at locating natural hydrogen. Company representatives asked the board to reduce a 250-foot setback from subsurface drainage tiles to a 50-foot buffer — or to a performance standard of 0.5 peak particle velocity (PPV) measured by on-site monitors — and to expand road miles covered by the permit from about 240 to roughly 370 miles, including some paved roads.
