findings by forwarding a copy of the enclosed report.
This report is being issued as a Notice of Deficiency (NOD) due to the following:
- Influent sampler temperature exceeded six degrees Celsius;
- Effluent sampler was not collecting a minimum of 100 mis. per aliquot;
- Five bulbs (ultraviolet disinfection system) were not operational and had not been replaced.
All above -noted findings are violations of the subject NPDES Permit and North Carolina General Statute (G.S.) 143-215.1
as detailed in the Influent Sampling, Effluent Sampling, and UV Disinfection Sections of the attached report. Please be
advised that G.S. 143-215.6A provides for a civil penalty assessment of not more than twenty-five thousand dollars
($25,000.00), or twenty-five thousand dollars ($25,000.00) per day when the violation is of a continuing nature, against any
