Richard Glenn, founder of Glenn Underwater Services, LLC (GUS) has received a patent from the U.S. Government (9,903,521 B2) for a remote pipeline plug. The plug was developed to prevent further release of coal ash into the Dan River from the damaged storm water pipe beneath the ash basin at the Decommissioned Dan River Steam Station. There are over 150 pipelines throughout the U.S. and internationally that have been abandoned and repaired by using this system.
