Dear Mr. Wood:
In response to your permit minor modification request received on February 12, 2024, and
subsequent additional information received on May 8, 2024, we are forwarding herewith Permit No.
WQ0004563 dated May 24, 2024, to the City of Hickory for the continued operation of the subject residuals
management program.
Modifications to the subject permit are as follows:
➢ The Division has added the Henry Fork WWTP (Permit No. NC0040797) as an approved
residual distribution facility, with an approved annual dry tonnage of 4,468 dry tons per year
(DT/yr) not to exceed a combined total of 14,000 DT/yr with the Hickory Regional Compost
Facility (RCF).
➢ The Division has re-added the existing treatment and storage units for the Hickory RCF to the
Facility Description on Page 1 because the Division has permitted them as part of the subject
permit.
This permit is effective from the date of issuance through December 31, 2024, shall replace Permit
No. WQ0004563 issued on August 19, 2019, and is subject to the conditions and limitations specified
therein. The Permittee shall submit a renewal application no later than July 4, 2024.
Please pay attention to the monitoring requirements listed in Attachment A for they may differ from

1. Maximum Dry Tons per Year is the quantity of residuals approved for land application from each permitted facility.
2. Analyses to demonstrate that the residuals are non-hazardous (i.e., TCLP, ignitability, reactivity, and corrosivity) as stipulated under permit Condition IV.3.
3. Testing of metals and nutrients as stipulated under permit Condition IV.4.
4. Analyses of the pathogen and vector attraction reductions as stipulated under permit Condition IV.5.
5. Class A non-biological residuals are exempt from meeting the pathogen and vector attraction reduction requirements in Con dition IV.5, provided the Permittee does not mix them with residuals
generated during the treatment of domestic wastewater, the treatment of animal processing wastewater, or the biological treat ment of industrial wastewater. The Permittee shall treat and process
Class A non-biological residuals in a manner as not to meet the definition of “Biological Residuals” as defined in 15A NCAC 02T .1102(6).
6. Monitoring frequencies are based on the actual dry tons applied per year using the table below unless specified above.

7. The Permittee shall only generate up to 14,000 DT/yr of Class A residuals for distribution, which is a combined total between the Hickory RCF and the Henry Fork WWTP. The Permittee plans

The Division shall not require sampling if no land application events occur during the required sampling period. The annual report shall include an explanation for missing sampling data.
The United States Environmental Protection Agency (US EPA) may require Permittees that submit annual reports to their agency to make up the missed sampling. Contact the US EPA for
