Enclosed is a copy of the Compliance Sampling Inspection Report for the inspection conducted at
the subject facility on June 13, 2018, by Mr. Wes Bell of this Office. Please inform the facility's
Operator -in -Responsible Charge (ORC) of our findings by forwarding a copy of the enclosed report. The
results of the effluent samples will be forwarded under separate cover.
It is requested that a written response be sent to this Office by July 13, 2018, detailing the actions
taken to ensure all data is properly reported on the eDMRS and the facility is properly visited (weekly) by
either the designated ORC and/or Backup ORC, as discussed in more detail in the Record
Keeping/Summary Section of the attached report. In responding, please address your comments to the
attention of Mr. Bell.
Should you have any questions concerning this report, please do not hesitate to contact Mr. Bell
at [phone], or via email at wes.bell(c-r�,ncdenr.gov.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
RECORD KEEPING SECTION cont'd:
On several occasions throughout the review period, effluent values (TSS, lead, copper, turbidity) were
not reported down to the analytical method's detection/reporting limit (a "0" was reported). Please be
advised that the subject permit requires that all data generated must be reported down to the minimum
detection or lower reporting level of the test procedure [Permit Condition Reference: Part II Section D
(4) Test Procedures].
Incorrect units of measurement was listed for the effluent salinity result (should be reported as ppth
instead of ppt). Please be advised that ppt represents parts per trillion and ppth represents parts per
thousand in DWR's eDMR system.
An effluent iron analysis was performed in February 2018; however, the result was not reported on the
eDMR. Please be advised that the results of all tests on the characteristics of the effluent, including
but not limited to NPDES Permit monitoring requirements, must be reported [Reference: 15A NCAC
.0506 (J)].
The reported flows on the eDMR for 8/23/17, 9/26/17, 10/26/17, 12/5/17, 12/14/17, and 2/8/18 should
be verified as being properly reported. In addition, the days (2/16/18 and 2/21/18) the ORC was noted
as being on-site should also be corrected. All eDMRs during the review period (July 2017 — March
2018) should be reviewed for all parameters (including ORC visitations and flow) and revised (if
applicable). In addition, the ORC and staff must ensure that all sampling dates, collection and analysis
times, analyst initials, and true gel standard value are documented.
The revised June 2017 eDMR (as a result of the previous inspection) did not appear to have the correct
flow value on 6/27/17. The June 2017 eDMR should also be revised if the flow was incorrectly
reported.
The facility is currently classified as a Grade 1 Physical -Chemical Water Pollution Control Treatment
System (WPCTS). The treatment facility was not visited by either the designated ORC or Backup
ORC during the week of January 7, 2018. Please be advised that a Grade I Physical -Chemical
WPCTS must be visited by the designated ORC and/or Backup ORC on a weekly basis (References:
NPDES Permit Condition Part ll, Section C (1) Certified Operator and 15A NCAC 08G .0204). Note:
The facility was visited by an operator (not certified/designated) during this week.
LABORATORY SECTION cont'd:
The ORC was not performing post -analysis calibration checks on the dissolved oxygen, pH, and total
residual chlorine meters following field analyses at multiple sites. Post -analysis calibration checks
must be performed in accordance with the NC Wastewater/Groundwater laboratory certification
approved procedures for the analyses of dissolved oxygen, pH, and total residual chlorine.

Comment: The records reviewed durina the inspection were oraanized and well maintained. Discharae
Monitoring Reports (eDMRs) were reviewed for the period July 2017 through March 2018.
No violations of effluent limited parameters were reported and all monitoring frequencies
were correct. Effluent chronic toxicity failures were reported in September 2017, December
2017, and March 2018: however, chronic toxicity is a monitor only requirement. See
"Summary" Section for additional comments.
