SUBJECT: Compliance Evaluation Inspection Report
J.D. Mackintosh WTP
Certificate of Coverage NCG590013 under NPDES General Permit NCG590000
Alamance County
Dear Mr. Thomas:
On September 6, 2018, Paul DiMatteo of this office met with you, operator in responsible charge
(ORC), to perform a Compliance Evaluation Inspection on the subject wastewater treatment facility. This
type of inspection consists of two basic parts: an in-office file review and an on-site inspection of the
treatment facility. The attached inspection form notes the areas that were evaluated for this inspection. The
findings and observations are outlined as follows. -
I. Permit
The general permit became effective on August 1, 2014 and will expire on July 31, 2019. A copy of
the current permit was available during the inspection. The facility was as described in the permit.
II. Self-Monitoring Program
A review of discharge monitoring reports (DMRs) from December 2016 through July 2018 revealed
no actioned violations. Sampling is being conducted at the location and frequency specified by the permit.
One composite whole effluent toxicity sample is required annually. Mr. Thomas said the sample is collected
by hand, by filling a 250-milliliter (ml) sample jug every hour during a time that the effluent pumps are run
continuously and combining the aliquots./The flow for the day should be reviewed and aliquot volumes
adjusted to ensure the sample is proportional to the flow, with no aliquot being less than 100 ml. Mr. Thomas
said he may set up a continuous drip line to take the sample. In this case, care should be taken to ensure
the sample is properly preserved during collection (e.g. by refrigeration).
The facility measures residual chlorine, pH and temperature at the on-site laboratory under the City
of Burlington's WWTP lab certification,#188. Other analyses are performed by Burlington's main laboratory.
Field parameter calibration records and procedures appeared acceptable, save for the digital thermometer
used to measure effluent temperature, which should be checked against an NIST-traceable thermometer

yearly. Note, however, that the General Permit does not require effluent temperature measurement, but
such measurements must be reported if conducted.
Ill. Records/Reports
Copies of DMRs, operator visitation logs, daily operation sheets, maintenance reports, lab reports
and chain-of-custody forms were available for review during the inspection. DMRs and lab data are
maintained according to the permit. DMRs include all permit parameters. A comparison of submitted data
with available field lab bench sheets revealed no errors or concerns. Non-field bench sheets are maintained
at Burlington's main laboratory and were not evaluated during the inspection.
IV. Flow Measurement
Effluent flow is measured using a Venturi meter set in the effluent pump force main and recorded
using SCADA. The meter is calibrated quarterly by Instrument Services, Inc. The last calibration was
conducted in June, 2018.
V. Operations and Maintenance
The plant is operated as required. All operators are properly designated and hold adequate
certifications. The facility appeared to be well operated and managed.
VI. Facility Site Review
The plant has two settling lagoons that are used interchangeably to manage filter backwash. Lagoon
#1 was down for sludge clearing, which is handled by EMA Resources. No problems were noted during the
inspection.
VII. Effluent/Receivinq Waters
Treated effluent is discharged to Big Alamance Creek just below the Lake Mackintosh dam, class
WS-V; NSW waters in the Cape Fear River Basin. Effluent appeared clear with no visible impact to the
receiving stream.
The compliance evaluation inspection is satisfactory. If you have any questions regarding the
inspection or this report, please contact Paul DiMatteo at [phone] or me at [phone].
Sincerely,
