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. 0 c%A.-41__A_Aj-.---. ip©ROWIN Charles Brown, Manager Town of Mount Olive AUG 0 2 2011 DENR-WA ER• ALl POINT SOURCE BRANCH • NPDES PERMIT APPLICATION - SHORT FORM C - WTP For discharges associated with water treatment plants Mail the complete application to: N.
