SUBJECT: Compliance Evaluation Inspection
United Chemi-Con WWTP
NPDES Permit No. NC0000019
Ashe County
Dear Mr. Katz,
On August 21, 2018, Kelli Park and Gary Hudson of this office met with John
Turner, operator in responsible charge (ORC), to perform a Compliance Evaluation
Inspection on the United Chemi-Con wastewater treatment system. 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 Environmental Protection Agency inspection form
notes the areas that were evaluated for this inspection. The findings and observations
are outlined below:
I. Permit
The NPDES permit became effective October 1, 2016, and expires on March 31, 2021.
There are multiple'outfalls at this plant. Primarily outfall 001 and 006 are used. Outfall
001 discharges the air compressor and cooling water effluent, while outfall 006 is the main
wastewater discharge from the plant. Outfalls 003 and 007 are not in use. Mr. Turner
mentioned that they could be used as backups to the main outfalls if there was to be a
problem.
II. Self-Monitoring Program
A review of the monthly discharge monitoring reports (DMR) for the period January 2017
through August 2018 showed that the facility complied with all permit limits.

United Chemi-Con,August 21,2018
Grab samples are taken from the effluent outfall 006.Time composite samples are taken "
from outfall 001. Three hundred milliliters of effluent are sampled every 30 minutes. This
is acceptable due to the flow being variable, rather than sampling proportionally to the
flow. The amount of flow through outfall 001 is directly tied to plant production and the
non-contact cooling water that is needed.
Ill. Records/Reports
The permit and visitation log are located on site and show visitation times and plant
conditions. Chain of custody forms are in good order. All required monitoring was
performed per the frequencies specified in the NPDES permit.
Miss Park noted no data transcription discrepancies from bench sheets to DMRs in her
documentation review.
IV. Flow Measurement
The instantaneous flow at outfall 006 is obtained by measuring the height of the water in
a 1-inch parshall flume and then converting it to flow.
There is a Stevens, Model 61 R flow meterat outfall 001 and it was calibrated this year.
V. Operations and Maintenance
The wastewater treatment plant appeared to be well maintained and operated. The ORC
and backup ORC are sufficiently qualified to be running the plant.
VI. Facility Site Review
All components of the 0.20 million gallons per day facility appeared to be functioning
properly. The influent goes through a bar screen, and flows through an Imhoff tank for the
solids to settle out. Mr. Turner mentioned that soda ash is sometimes added during the
summertime to help keep the pH at an acceptable level. The flow is then distributed
through a sand bed, which is evenly raked and has no odor. There was no evidence of
ponding in the sand bed. The dosing lines and concrete pads seemed to be in good
condition. Effluent is not recirculated, it goes straight from the sand beds to the receiving
stream. There is a clear path to where the effluent pipe discharges into the receiving
stream.
VII. Effluent/Receiving Waters
The effluent from the facility was clear the day of inspection at both outfall 001 and 006.
Effluent from both outfalls is discharged into the North Fork of the New River which is
classified as class C, high quality, water.

VIII. Sludge Maintenance and Handling
Sludge was reported to be pumped about once or twice a year. Pumping is done by Doug
Cox Backhoe Service.
IX. Conclusions
The compliance evaluation inspection is satisfactory. Mr. Turner maintains and operates
the facility in a good manner. His efforts to comply with the permit are appreciated. If you
have any questions regarding the inspection or this report, please contact Kelli Park or
me at [phone].
Sincerely,
