SUBJECT: Compliance Evaluation Inspection
Calico Pit Sand Dredge Site
Permit No: NCG520083
Caldwell County

Dear Permittee:

The North Carolina Division of Water Resources (Division) conducted an inspection of the Calico
Pit sand dredge site (4338 Calico Road) on September 19, 2022. This inspection was conducted
to verify that the facility is operating in compliance with the conditions and limitations specified
in NPDES Wastewater Permit No. NCG520083. A summary of the findings and comments noted
during the inspection are provided in the enclosed copy of the inspection report.

The compliance evaluation inspection was conducted by Division of Water Resources Staff from
the Asheville Regional Office. The following deficiency(s) was noted during the inspection:

Inspection Area Description of Deficiency
Signage Warning signs upstream of dredging operation were
not visible during site inspection

Please be aware that your permit requires warning signs to be placed on each side of Lower
Creek, a short distance upstream of the dredging operation to warn canoeists and other
recreation users of the operation. No signage was visible on the day of the inspection.

As a reminder, your permit requires semi-annual monitoring during active dredging if runoff
from the excavated materials reaches Lower Creek. While the discharge is occurring, you’re
required to estimate the flow rate and collect turbidity samples in Lower Creek upstream and
downstream of the discharge. The flow rate can be estimated (i.e., gallons per minute) or
measured using a graduated bucket, pipe, and stopwatch. The water samples should be sent to
a commercial laboratory for analysis. The nearest commercial laboratory is Water Tech

Laboratories in Granite Falls. The laboratory can be reached at [phone]. The monitoring
results should remain in your possession and be made available during your next scheduled site
inspection.

The Division can pursue enforcement action for permit violations and any additional violations
of State law. To prevent further action, carefully review the deficiency and address the cause(s)
of non-compliance.

If you should have any questions or concerns, please do not hesitate to contact Brett Laverty
with the Water Quality Regional Operations Section in the Asheville Regional Office at (828)
296-4681.

Sincerely,

G. Landon Davidson, P.G., Regional Supervisor
