Subject: Acknowledgement of Receipt of the 2021 Annual Report (AR)
Town of Boiling Springs - Permit No.: WQ0018352
Land Application of Residuals
Cleveland County
The 2021 AR was received by electronic submittal on February 25th, 2022, and a paper copy was
received at the Mooresville Regional Office (MRO) on March 14th, 2022. The MRO appreciates the
inclusion of the spreadsheet with all conversions and the Sodium Adsorption Ratio (SAR) calculation
sheet. These additional sheets provided for a more efficient review.
It was noted the Calcium, Magnesium and Sodium data entered in the SAR calculation sheet does not
match the lab results from the September 2021 sampling event. Ca=487,000 ug/L, Mg=42,000 ug/L, and
Na=52,100 ug/L, result in a SAR=0.61 by MRO calculation. This information is noted for assistance with
future reports as your 2021 AR indicates the overall program requirements were met.
You may contact Maria Schutte via email (Maria.Schutte©ncdenr.gov) or phone [phone]) with any
questions about this report or your permit.
Sincerely,
DocuSigned by:
