REGAN Secretary LINDA CULPEPPER Director Mr. Andy Smith (via email) Assistant Director Water Resources City of Statesville P.O. Box 1111 Statesville, North Carolina 28687 Dear Mr. Smith: NORTH CAROLINA Environmental Quality February 1, 2019 Subject: Compliance Inspection Reports City of Statesville, Iredell County Permit WQ0006245 Sta—Lime Distribution Program Permit WQ0014543 Emergency Land Application On January 23rd, 2019, the Mooresville Regional Office (MRO) completed Compliance Inspections for the above -stated facilities. The inspections included records review and residuals processing review of the Fourth Creek WWTP facility. A review of the storage at the Fourth Creek WWTP was performed as part of the inspection. The MRO would like to thank Kenneth Galloway for his time during these inspections. Permit WQ0006245: Log entries for the lime stabilization analysis and cross-referenced records for the pH meter calibration were well organized. O&M records were reviewed and appear to be well organized and up to date. During the site visit, there was a limited amount of residual material present on the Fourth Creek storage pad area. The storage pad at the fourth creek facility is experiencing issues with the product becoming saturated due to high precipitation. This concern is addressed further in the BIMS report. Please request that Prism Laboratories report the SAR calculations with the variables populated, rather than presenting the general formula. This will allow for quick verification of these values. This concern was addressed during the site visit. The corrected analytical reports are expected to be present in the Annual Report for this permit. This permit expires on September 30, 2020. Please be sure to submit the permit renewal application at least 180 days prior to the permit expiration date.

Confirmation was made that dedicated land for this permit continues to be in place. The permittee was reminded that if the dedicated land was removed from available use, this permit may become invalid. This permit expires on February 28, 2019. A renewed permit has been issued and it will become effective on March 1, 2019. A file review of the O&M and analytical data for the Third Creek WWTP residuals was reviewed during this site visit. Please update all contacts and ORC's and persons to be associated with these permits. Changes can be made by submitting Water Pollution Control System Operator Designation Form as stipulated in NCAC 15A 8G .0201. A copy of the link has been attached to this email. Overall the facilities were found to be compliant with the permit. The attached reports should be self-explanatory. However, should you have any questions, please feel free to contact me at 704-235-2198 or by email at edward.watsonnncdenr.gov. Sincerely, CA DocuSigned by: 4144W H PLU" F161 FB69A2D84A3... Andrew H.

Due to the large amount of precipitation experienced this past year, a limited amount of the Sta-Lime product has been produced this past year. This data will be reflected in the AR for 2018. Although the pad is scraped daily to contain the residuals, the drain at the storage pad has become obstructed as a result of the saturated residual product flowing across the pad to the drain. This drain returns to the head of the WWTP. The flow of the treated residuals entering the drain results in the product re-entering the treatment process adding cost to the operation. Mention was made by Ken Galloway during the site visit that there has been a discussion about installing an over -head covering to keep the treated residuals from becoming saturated. Another alternative is to clean -out to the area of the old sand filter beds, installing asphalt flooring and using this dis-used area for additional storage. The old sand filter beds already have dividing walls that will keep the residuals separated. This also may be more cost-effective than erecting an additional roof to cover the third and fourth creek residuals. The contract laboratory reporting of the calculation for residual parameters such as PAN, SAR, ESP, etc., continue to not be consistently recorded. A Notice of Deficiency (NOD) was issued on the 2017 AR for the reporting inconsistency. It is the hope that this mention will allow the analytical data to be corrected prior to the AR being submitted for 2018.
