SUBJECT: 2023 Residuals Annual Report Review
Danville Residuals Land Application Program
Permit No. WQ0036561
Caswell County
Dear Mr. Johnson:
On May 14, 2023, Division of Water Resources staff Caitlin Williams completed a review
of the 2023 residuals annual report. This review reflected compliance with the subject
permit. The following item of concern was noted:
• Per Permit Condition 111.3, a land application notification is required at least one
business day in advance of conducting any land application notification activity. A
review of available records shows the Winston Salem Regional Office did not
receive a land application notification for field CS-14 prior to application at that
field. Moving forward, be sure to notify this office at least one day before land
application commences.
Please refer to the enclosed inspection report for additional comments and observations.
If you have any questions, please contact Caitlin Williams at the letterhead address and
phone number, or by email at caitlin.williams(c�deg.nc.gov.
Sincerely,
Docu Signed by,

Inspection Summary:
On May 14, 2023, Division of Water Resources staff Caitlin Williams completed a review of the 2023 residuals annual report.
This review reflected compliance with the subject permit.
The following item of concern was noted:
• Per Permit Condition 111.3, a land application notification is required at least one business day in advance of conducting
any land application notification activity. A review of available records shows the Winston Salem Regional Office did not
receive a land application notification for field CS-14 prior to application at that field. Moving forward, be sure to notify this
office at least one day before land application commences.
Other observations:
• A single application event was conducted in the 2023 calendar year. Four sample events were completed prior to land
application to confirm residuals were compliant with all permit limits.
• Fecal and 30 day bench were used to meet pathogen and vector reduction requirements. Fecal samples were collected
on 4/3/23, 4/18/23, 5/1/23, 5/15/23. 30 day bench samples were collected 5/23/23 (x2) and 6/1/23 (x2).
• Nutrient and metal samples were collected on 4/3/23, 4/18/23, 5/1/23, 5/15/23. TCLP sample was collected on 4/3/23.
• The pathogen and vector attraction reduction form for the 5/1/23 sample event reported incorrect fecal values. Mr. Brent
Collins is submitting an amended copy of the annual report with the corrected form. The fecal results provided for this
sample event reflect compliance with the subject permit.
