Subject: Application No. WQ0004563 - Additional Information Request #1
Mr. Zachary Mega,
The Division of Water Resources reviewed the Class A Residuals Distribution Permit Modification submitted
by The City of Hickory. This letter provides a response to each of the review comments received in the letter
dated April 12, 2024. Sections that received no comments are not addressed.
F. Cover Letter
1. Acknowledged.
2. The O&M Plan has been revised.
3. The listed TCLP, ignitability, corrosivity, and reactivity sampling frequency has been revised
to "Annually".
4. There are no changes to the potential residuals contributor list shown in Attachment A of
the Final Permit issued on August 19, 2019. The residuals management plan has been
revised.
5. The residuals management plan has been revised to reflect the correct metals analysis
frequency.
G. Summary for Form: RSC 06-16
1. RSC 06-16 has been revised to reflect the maximum residuals production for both the
existing compost facility and the Henry Fork Biosolids Handling facility. A third column was
added to reflect a combined distribution of not more than 14,000 DT/year. Per email
communication, this will cover the potential partial operation of both facilities during
start-up of the Henry Fork Biosolids Facility.
A revised copy of RSC 06-16 is enclosed within. The revisions to the O&M plan, program information, and
residuals quality information will be submitted when completed, prior to distribution of Class A residuals per
Comment A.

Division of Water Resources RESIDUALS SOURCE CERTIFICATION
INSTRUCTIONS FOR FORM: RSC 06-16
Please use the following instructions as a checklist in order to ensure all required items are submitted. Adherence to these
instructions and checking the provided boxes will help produce a quicker review time and reduce the amount of additional
information requested. Failure to submit all of the required items will lead to additional processing and review time for the
permit application. Unless otherwise noted, the Applicant shall submit one original and two copies of the application and
supporting documentation
For more information, visit the Water Quality Permitting Section's Non -Discharge Permitting Unit
General — This certification provides detailed information of residuals source generating facility and its residuals quality for land
application, distribution, or disposal in accordance with 15A NCAC 02T .1100. Do not submit this certification for review without
a corresponding application form (FORM: RLAP 11-15, FORM: DCAR 11-15, or FORM: SDR 11-15).
Unless otherwise noted, the Applicant shall submit one original and two copies of the application and supporting documentation listed
below.
A. Residuals Source Certification (FORM: RSC 11-15):
® Submit the completed and appropriately executed Residuals Source Certification (FORM: RSC 11-15) form. Please do not
make any unauthorized content changes to this form. If necessary for clarity or due to space restrictions, attachments to the
application may be made, as long as the attachments are numbered to correspond to the section and item to which they refer.
® For new or renewed permits, submit a separate certification for each source facility.
® For modified permits, submit a separate certification for only those facilities that are affected by the proposed modification.
® Complete the residuals source facility summary page. List all new, renewed, or modified facilities.
B. Residuals Source -Generating Facility Information:
® For each source facility, attach the following:
® Vicinity map - A vicinity map that shows the location of the facility and meets all of the criteria in the "Map Guidance for
Residuals Land Application Permits".
® Process flow diagram and/or narrative - A detailed narrative and/or process flow diagram that describes how the residuals
are to be generated, treated, processed, and stored at the facility.
® Quantitative justification for residuals production rate - A quantitative justification for the value provided in Item I. 8.
Ensure that the amount of residuals listed is the maximum amount expected to be generated by the facility for the life of
the permit. In addition, ensure that this amount is equivalent to that which is actually to be land applied, distributed,
and/or disposed, including any chemicals, amendments, or other additives that are added to the residuals during
processing.
® Sampling plan - A detailed sampling plan for the residuals source -generating facility. Ensure that the plan identifies
sampling points, sampling frequency, sample type, as well as the Division -certified laboratory to be used. In addition,
ensure that the plan details how the facility and/or the residuals are monitored for any applicable pathogen reduction and
vector attraction reduction requirements. Note that all sampling and monitoring must be completed on the residuals as
they are to be land applied, distributed, and/or disposed.
C. Residuals Quality Information:
® For each source facility, attach the following:
® Laboratory analytical reports and operational data - reports for all laboratory analyses used to complete this certification.
® Documentation that the facility complies and/or the residuals comply with any applicable pathogen reduction and vector
attraction reduction requirements.
® For new facility that may have not yet been constructed and analytical results of residuals cannot be obtained, please
attach analytical results of residuals generated from a similar facility along with the description of similarities of the two
facilities.
