The monthly average effluent BODS and Total Suspended Solids concentrations shall not exceed 15% of the respective influent value (85% removal). 3. The quarterly average for Total Phosphorus shall be the average of composite samples collected 2/month during each calendar quarter (January -March, April -June, July -September, October -December). 4. For a given wastewater sample, TN = TKN + NO2-N + NO3-N, where TN is Total Nitrogen, TKN is Total Kjeldahl Nitrogen, and NO2-N and NO3-N are Nitrite and Nitrate Nitrogen, respectively. 5. Total Nitrogen Load is the mass load of Total Nitrogen discharged in a given period of time. See special condition A. (2.), Calculation of TN Loads. 6. A statewide Total Maximum Daily Load (TMDL) for Mercury has been approved by the US EPA. Municipal wastewater discharges with NPDES permits must monitor or limit Mercury to comply with the TMDL. THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM IN OTHER THAN TRACE AMOUNTS. A. (2). CALCULATION OF TOTAL NITROGEN LOADS a. The permittee shall calculate monthly and annual TN Loads as follows: i. Monthly TN Load (lb/month) = TN x TMF x 8.34 where: TN = the average TN concentration (mg/L) of the samples collected during the month TMF = the Total Monthly Flow of wastewater discharged during the month (MG/month). 8.34 = conversion factor, from (mg/L x MG) to pounds ii. Annual TN Load (lb/year) = Sum of the 12 Monthly TN Loads for the calendar year The permittee shall report monthly Total Nitrogen results (mg/L and lb/month) in the appropriate discharge monitoring report for each month and shall report each year's results (lb/year) with the December report for that year. A. (3). TOTAL NITROGEN ALLOCATIONS a. The following table lists the Total Nitrogen (TN) allocation(s) assigned to, acquired by, or transferred to the permittee in accordance with the Neuse River nutrient management rule (T15A NCAC 02B .0234) and the status of each as of permit issuance. For compliance purposes, this table does not supercede any TN limit(s) established elsewhere in this permit or in the NPDES permit of a compliance association of which the permittee is a co-permittee member. ALLOCATION TYPE SOURCE DATE ALLOCATION AMOUNT (1) STATUS Estuary (lb/yr) Discharge (lb/yr) Base Assigned by Rule 12/7/97; 2,275 4,550 Active (T15A NCAC 02B 4/1/03 .0234) Footnote: 1. Transport Factor = 50% b. Any addition, deletion, or modification of the listed allocation(s) (other than to correct typographical errors) or any change to active status of any of the listed allocations shall be considered a major modification of this permit and shall be subject to the public review process afforded such modifications under state and federal rules.

Have appropriate permits/clearances concerning other Federal/State requirements been obtained? ❑ Yes ❑ No Describe briefly: N/A B.6. EFFLUENT TESTING DATA (GREATER THAN 0.1 MGD ONLY). Applicants that discharge to waters of the US must provide effluent testing data for the following parameters. Provide the indicated effluent testing required by the permitting authority for each outfall through which effluent is discharged. Do not include information on combine sewer overflows in this section. All information reported must be based on data collected through analysis conducted using 40 CFR Part 136 methods. In addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC requirements for standard methods for analytes not addressed by 40 CFR Part 136. At a minimum effluent testing data must be based on at least three pollutant scans and must be no more than four and on -half years old.

Page 9 of 22 SLUDGE HANDLING NARRATIVE At design flow the Maury Sanitary Land District WWTP is anticipated to produce approximately 330 lbs/day of excess activated slugged (1,583 gpd at 2.5%) based on a flow of 225,000 gpd and influent BOD5 of 270 mg/l. Excess sludge is wasted from the oxidation ditch to an adjacent sludge holding lagoon with a volume of approximately 2.7 million gallons representing a detention time of 1,706 days. Wasted sludge is allowed to decompose in the lagoon. Cleaning of the lagoon will be accomplished once significant accumulations are observed. Supernatant from the lagoon is returned to the WWTP. Groundwater contamination due to the use of Cell No. 1 for sludge digestion/holding is not anticipated to be a problem. Cell No. 1 was constructed in natural clays with a coefficient of vertical permeability of less than 1.0 x 10-' cm/sec as reported in the Soils Report prepared by Atec Associates. Clays were identified in all borings at the site extending to depths of 8 to 17 feet with a groundwater level identified at 20 feet below ground. A total of three groundwater monitoring wells are existing at the treatment plant site. L.A.
