Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Melanie Kemp, with the Asheville Regional Office, visited the Ameri-CON Materials, Inc-Adger Mine
site on October 19, 2023 to inspect the site for a new permit application (general permit NCG520000,
permit no. NCG520128). Jason Deck, site representative with Ameri-CON Materials Inc., was present
and assisted with the inspection.
Sand from the Green River will be mined utilizing a hydraulic pump mounted on a barge (barge not
present during inspection). The sand slurry will be transported to the on-site processing plant via a
pipeline where the sand material will be extracted. Wastewater will then be conveyed to a settling
pond before being discharging back into the Green River. During the inspection, the sand slurry
pipeline and processing plant were installed, but not operational. The connection between the
processing plant and settling pond still needs to be completed and covered in fill dirt. Additionally,
riprap and other stabilization measures, as well as a cleanout marker, need to be installed within the
settling pond. See attached photographs.
An additional inspection should be performed after the mine is operational.
