SUBJECT: NOTICE OF VIOLATION
Tracking Number: NOV-2020-LV-0663
Permit No. WQ0023580
Cove Key Townhomes on Lake Norman WWTP
Iredell County
Dear Mr. Hawkins:
A review of the June 2020 Non -Discharge Monitoring Report (NDMR) for the subject facility revealed the
violation(s) indicated below:
Limit Exceedance Violation(s):
Sample Limit Reported
Location Parameter Date Value Value Type of Violation
001 Nitrogen, Ammonia Total (as 6/17/2020 6 6.4 Daily Maximum Exceeded
N) (00610)
001 Nitrogen, Ammonia Total (as 6/17/2020 4 6.4 Monthly Average Exceeded
N) (00610)
The reported Ammonia exceedances were confirmed by email on 9-4-2020 from Mr. Brandon Long (ORC). This is
the second Ammonia violation in two consecutive sampling months. In response to the March 2020 violation an
Ammonia resample was taken on 6-3-2020 with results (0.27 mg/L) below both weekly and monthly limit values;
however, it is unacceptable to wait 3 months or until this office requests a resample to document return to
compliance. Resampling should be conducted as soon as possible after first knowledge of the exceedance.
Furthermore, Permit Condition IV.11.d. requires notification to the Division of Water Resources (DWR) - Mooresville
Regional Office (MRO) within 24 hours of first knowledge of none compliance. DWR-MRO staff did not receive that
notification in either March or June sampling exceedances. One reason for this permit condition is to allow timely
discussion of a plan to mitigate ongoing issues.

A written response is requested by October 19t", 2020 with an explanation of measures taken to
alleviate the Ammonia violations at the WWTP and how future violations will be reported to the DWR-
MRO in a timely manner.
DWR-MRO staff recommended another resampling for Total Ammonia in the 9-4-2020 email response to Mr. Long,
again to verify the system has returned to normal operation. The sample results should be emailed to
[e-mail] upon receipt.
Remedial actions, if not already implemented, should be taken to correct any noted problems. Please be aware
that non-compliance with your permit could result in enforcement action by the Division of Water Resources for
these and any additional violations of State law. The Mooresville Regional Office encourages you to take all
necessary actions to bring your facility into compliance.
If you should need any assistance or would like to discuss this non-compliance situation, please contact Maria
Schutte of the Mooresville Regional Office at 704-663-1699 or at [e-mail].
