(2) Section are no longer necessary. The TMF value and A. (2) Section were needed to calculate the TN Load which is no longer required. 2) A TN Load calculation, Monthly and Annually, has been removed from this permit. The Division has determined that the TN Load impact from this facility does not warrant further evaluation at this time. As nutrient conditions or other factors change in the Neuse River Basin the Division will re-evaluate this permit requirements. If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter.

Therefore, the final permit has been revised to remove TN Load requirements including TMF. Will keep semi-annual frequency TN & TP. Current Date: March 18, 2008 Prepared by: Ron Berry Previous Renewal Permit Effective Issue Date: November 1, 2003 Existing Permit Expiration Date: April 30, 2008 Renewal Permit Expiration Date: April 30, 2013 Discharge: UT to Basil Creek Basin: Neuse Classification: B, NSW General: The renewal application was returned to the consultant, return #2270, on December 27, 2007. There were several missing items. A follow up letter was also send to Aqua North Carolina, Inc. stating the application could not be process until a correct application was provide. The correct application was received January 15, 2008. A fast track dechlorination AtC was issued in March 2005. Aqua North Carolina, Inc. became the new owner in 2007. The application stated the permitted flow monthly average would be 0.00171 MGD. Effluent Limited criteria are: - Flow, monthly average max, monitor to determine TN Load - TSS, daily max, monthly average max - TN, calculate allocated N lbs - (NO2-N + NO3-N), monitor to determine TN - TKN, monitor to determine TN - TP, monitor only - Total Iron, monitor Water Quality Limited criteria is: - pH, daily range limit - TRC, daily max. The 2008 renewal application included a copy of the Sludge Management Plan. Process: Three parallel sand filter provide water treatment for the well water. Chlorination is done upstream of the filters. The sand filters backwash and other waste water are discharged through a tablet dechlorinator and then to a sand filter bed were the effleunt continues to the outfall. The accumulated sludge in the sand filter is removed by a contractor as needed. March 2005 AtC given for tablet dechlorination treatment which is added to the waste water stream prior to entering the final sand filter. Discharge is to UT to Basal Creek. Numerous paperwork violations. Concerns: Flow effluent monitoring/reporting, per last permit it is estimated based on backwash events. DMR data review indicates monthly average flow would exceed the 0.00171 MGD monthly average so the permitted value was increased to 0.0025(BPJ). Page 1 of 1 TSS monitoring with Effluent Daily and Monthly Average Limits. Sample is grab. Will increase frequency to 2/month with previous and limits. DMR data review indicates no violations, daily value typically less than 5 mg/L. Settleable Solids with Effluent Daily and Monthly Average Limits. Sample is grab. One value at Daily Max. Will not continue per latest guidelines. Turbidity monitoring with Effluent Daily Limit. Sample is grab. No violations. Turbidity typically less than 10 ntu. Will not continue per latest guidelines. Iron monitoring, currently monitoring only. Sample is grab. Typically less than 5 mg/L. Will increase frequency to monthly. TRC monitoring with Water Quality Daily Limit. Sample is grab. Will need to modify footnote to state definition of chlorine additives, compliance date already enforced. Prior to compliance date had values above limit but installed dechlorination. Will increase frequency to 2/month. .pH monitoring with Water Quality Daily Limits. Requires grab sample. New requirement per latest guidelines. Frequency is 2/month. Total Nitrogen (TN) monitoring, currently monitoring only with measurements of TKN and (NO2- N + NO3-N). TN Load calculations and reports submitted monthly and annually. Sample is grab. Will maintain current frequency. Per DMR data TN Load annually is less than 3 lbs/yr. Total Phosphorus (TP) monitoring, currently monitoring only. Sample is grab. Will maintain current frequency. Based on DMR data TP less than 1 mg/L. Changes to renewal permit: 1. Continue all monitoring parameters and limits for TN, TN Load, TP as in existing modified permit. 2. Edit permit, owner name to reflect Aqua, updated component list. 3. Remove Settleable Solids and Turbidity. 4. Edit TRC existing footnote to show only definition for chlorine additive, increase frequency. 5. Edit Iron monitoring to increase frequency. 6. Edit TSS to increase frequency. 7. Add pH with limits. Rational For Changes: This WTP facility is a small discharger. The historical data indicates very small TN Load and TP. Does not have allocation or limit therefore will continue frequencies. Per guidelines need to add pH with limits and Total Manganese monitoring. All limited parameters need to be measured 2/month while monitored parameters of significance should be measured monthy. TRC footnotes need to clearly define the additives. The limit is enforced and no longer requires compliance time line.
