This letter is in response to our BOD violation for the month of October with a limit value of 5mg/l and a reported
value of 5.67mg/l. After some investigation and research, it was determined that the high BOD readings where
coming from a dirty composite sampler hose. Immediately after the dirty composite sampler hose was replaced
all BOD readings returned to normal. Sampling was conducted before the sampler and at the effluent during this
research and both came back with <2mg/l.
Accordingly, it is my belief that the Town of Siler City did not release high BOD into Loves Creek during this time
and that the BOD readings reported were faults positives completely related to the dirty composite sampler hose.

Unable to locate the source of the Cadmium, we have turned our efforts to removing the Cadmium from our
plant. We are currently in talks with the town engineer and a couple chemical companies to find the best way to
remove this from our system. If you should have any suggestion as to how we could locate the source or methods
as to how to remove this from our system, it would be greatly appreciated.

Dear Mr. Smith,
This letter is in response to the Notice of Violation for Cadmium and BOD for the month of May. We have
conducted numerous samples at business and pump stations throughout the collection system in an effort to
narrow down as to where the source of the Cadmium is from. With the inconsistency of its appearance in our
samples this has proved to be a difficult task.

3. The facility is certified for analyzing BOD, Fecal, TRC, pH Temp Ammonia, DO
(Certification #132). Log books were kept and showed that incubators are kept at acceptable
temperatures. pH buffers were within dates. Calibration logs were present. All other
parameters are analyzed by Meritech, Inc. Lab results, chain-of-custody forms, and DMRS
were complete and organized. June DMR data was compared to lab bench sheets; no data
transcription errors were noted. Samples were observed to be kept at proper temperature.
On November 14, 2017. Jason Robinson of the Raleigh Regional Office (RRO) conducted a
compliance evaluation inspection of the subject facility. The assistance provided by Mr. Chris
McCorquodale. Operator in Responsible Charge (ORC) was appreciated. The inspection report is
attached. The following observations were made:
Basins - Only used during high flowl ergencies. None were in 1
*
This facility was found to be compliant with NPDES permit conditions as a result of this inspection.
The plant is well maintained and documentation was found to be detailed, organized, and complete. If
you have any questions regarding the attached reports or any of the findings, please contact Jason
Robinson at: [phone] (or email: Jason.t.robinsonf7ncdenr.gov).
5. The right of way to the outfall was properly maintained. The effluent appeared clear and free
of solids. There were no visible detrimental impacts to the receiving stream.
• Four Equalizal
operation duringrthe time of the inspection.
• Sludge Transfer Station
• Lime Tower
• Dual oxidation ditches
• Alum feed station - Alum at the splitter box upstream of the clarifiers
• Dual Secondary Clarifiers - Sludge blanket tested in one at approximately 1.5 feet.
Clarifier is 16 feet deep.
• Four Tertiary Filters
• Chlorine Contact Chamber
• Sulfur Dioxide addition (Dechlorination)
• Solids removal area (screened and separated; trucked offsite as byproduct). Synagro
hauls sludge from the facility every 2-3 months. Hauling records were reviewed.
