Dear Mr. Greer:

Subject: Acknowledgement of Receipt of the 2020 Annual
Report for Hickory Regional Compost Facility (RCF)
and Catawba ORGRO Distribution Program
Permit No. WQ0004563
Distribution of Residual Solids (503)
Catawba County
The staff of the Mooresville Regional Office (MRO) has received and reviewed the 2020 Annual Report
(AR) for the Hickory Regional Composting Facility (RCF). This facility receives treated residuals from
partners of the consortium which is comprised of 9 separate facilities that transfer treated biosolids to
the RCF.
In the 2018 AR review, the MRO made a request that the Sodium Absorption Ratio (SAR) calculation be
presented in the AR. The formulas for Sodium Absorption Ration (SAR) and Plant Available Nitrogen
(PAN) continue to not be presented in the 2020 AR. Although the results of the tests appear to be
accurate, the calculations for these values are requested to be presented in future annual reports.
Overall the facility was found to be compliant with the permit.
The attached report should be self-explanatory; however, should you have any questions, feel free to
contact our office by phone at 704-235-2199 or by email at [e-mail].
