Mr. Brown—I'm starting to renew the subject permit, per your application.
QUESTION: Your previous permit described "green Sand"filter technology,yet your current application cover letter
mentions"conventional"treatment technology. Moreover,you have neglected to stipulate in your Application, Part 5.
These two technologies require different permitting strategies. Which treatment is true?

Town of Mount Olive
Gordon Street WTP

Dear Mrs. Sprinkle:
The Town of Mount Olive is requesting renewal of NPDES permit number NC0086801 for the backwash flow
from the Gordon Street WTP. The plant treats groundwater which is filtered with a combination of sand and
greensand filters. The greensand filters are not backwashed with a sodium solution.
The finished water is being fluorinated at this time, but the WTP is considering discontinuing the addition of
fluoride. We are requesting that permit be written so that fluoride monitoring/limits will be applicable only if
the town is adding fluoride. The current permit has a weekly monitoring requirement for iron and settleable
solids. The results for the settleable solids tests are consistently measured as a "Trace". The Town is
requesting that settleable solids be removed from the permit. The Town is also requesting a change in the
measurement frequency for iron from weekly to quarterly.
We appreciate your assistance in this matter. If you have any additional questions, please call Deems Blanton,
Water Plant Superintendent at 919/658-6213 or 919/738-1025.

sand filters. The filtered water is pH adjusted with caustic. Corrosion inhibitors are also
added after filtration.

facility:
Filter backwash water flows to a backwash holding tank. Declorinating chemical is added
to the backwash holding tank prior to each backwash cycle. The backwash is allowed to

Sludge Management Plan
Gordon Street WTP
NPDES# NC0086801
The Town of Mount Olive operates the Gordon Street Water Treatment Plant which uses
groundwater as the raw water source. The raw groundwater is filtered through a combination of
conventional and greensand filters. During the backwash cycle, any accumulated solids are
discharged to the backwash holding tank. This tank allows the solids to settle and thicken in the
bottom of the holding tank. The sludge is discharged to the sanitary collection system as needed
for ultimate disposal at the Town's wastewater treatment plant.
