Dear Mr. Boone,
I am writing to request rescission of our NPDES Permit (NCG5300000, COC NCG530131). I am submitting this
request because the permit no longer appears applicable to our operations. We do not raise fish in the water
that is regulated under this permit. At some point in the past, our activities were apparently deemed similar
enough to a fish farm to require coverage. However, our operations have changed over the years and while
there is still a discharge point on our property, the discharge consists of unaltered water from a natural spring.
The spring runs continuously at a rate of about 3 gallons per minute. The water flows through a series of
concrete basins which are used to grow aquatic plants (elodea and duckweed). This is a totally self-sustaining
system, and nothing is added to the water prior to discharge. The water is not treated in any way and the plants
are not fed or fertilized. Therefore, the discharge should consist solely of natural spring water.
After going through the concrete basins, the water is split with a portion going directly into a drainage culvert
adjacent to Haggard Avenue and a portion going into an on -site pond, located at the intersection of Haggard
Avenue and York Road. The pond is also used to grow aquatic plants (lily pads). Under normal conditions, the
pond only loses water to evaporation. During periods of extremely high rainfall, the water may overflow through
a drainpipe into the same drainage culvert as the spring water, however this occurs very infrequently.
Based on this information and the recommendation included on your 9/7/2022 Inspection Report, I respectfully
ask that Carolina Biological Supply Company no longer be regulated under this permit. If you need any additional
information, please let me know.
Sincerely,
Michael Richardson
