Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
On September 02, 2021, Mitchell Anderson and Brett Laverty from the Asheville Regional Office of
the Division of Water Resources (DWR) conducted a Compliance Evaluation Inspection of the sand
dredging operation, “Caldwell Pit” site, located off Rocky Rd along Lower Creek in Gamewell, NC
(NCPIN #: 2737193156). An employee (Lloyd) of Hoffman Paving & Grading was present during the
inspection. There was no dredging the day of the inspection.
During the site inspection, staff observed that the area around the long-armed track hoe and
stockpiled sand slopes away from the stream and appears to be redirecting effluent into adjacent
pasture and fields. Vegetated sand berms at the top of bank also prevent effluent from returning to
Lower Creek.
The streambank along Lower Creek appears to be overly steep as a result of dredging, but show no
obvious signs of erosion or bank failure. The operator is having some difficulty keeps cows from
accessing the stream through his dredge operation.
Two warning signs with black text on a white background were located upstream and downstream of
the dredge operation. However, signs in their current placement cannot be seen by canoeists and
other recreational water users on the river.
The permittee shall install warning signs, one on each side of the receiving stream(s), a short
distance upstream of the sand dredging operation to warn canoeists and other recreational water
users of the operation. The signs should include the following wording in 2 to 3-inch high white letters
on a red background:
CAUTION: SAND MINING OPERATION AHEAD
CRANES, FLOATS AND/OR SUBMERGED CABLES ACROSS RIVER.
BEACHING ON OR ACCESS TO SAND DREDGING SITE IS PROHIBITED.
Visibility of the signs should be maintained as necessary.
Required semi-annual flow and turbidity monitoring records were not provided during inspection upon
request. Lloyd indicated the semi-annual turbidity monitoring and the semi-annual flow estimates
were not completed for this site during the previous permit cycle. The ARO will be issuing a notice of
deficiency for failure to conduct the required monitoring.
