Fluoride monitoring applies if the facility backwashes with fluoridated, finished water. 4. Zinc should only be monitored if a Permittee uses zinc orthophosphate as a corrosion inhibitor. 5. Facilities using chloramination will be required to monitor ammonia nitrogen on a quarterly basis. Ammonia nitrogen monitoring only applies if the facility chloraminates. 6. Parameters should be monitored in conjunction with toxicity test. 7. See Attachment A (2.). All samples collected should be from a representative discharge event. There shall be no discharge of floating solids or visible foam in other than trace amounts. Permit NC0086011 A. (2.) CHRONIC TOXICITY MONITORING (QRTRLY) The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions. The effluent concentration defined as treatment two in the procedure document is 90%. The testing shall be performed as a Ceriodaphnia dubia 7day pass/fail test. The tests will be performed during the months of January, April, July and October. Effluent sampling for this testing shall be performed at the NPDES Permitted final effluent discharge below all treatment processes. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B. Additionally, DWQ Form AT-1 (original) is to be sent to the following address: Attention: North Carolina Division of Water Quality Environmental Sciences Section 1621 Mail Service Center Raleigh, N.C. 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Section at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly monitoring will begin immediately. Upon submission of a valid test, this monthly test requirement will revert to quarterly in the months specified above. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring requirements or limits. If the Permittee monitors any pollutant more frequently then required by this permit, the results of such monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT Forms submitted. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring.

RECEIVED JUN262009 DENR - WATER QUALITY POINT SOURCE BRANCH 1. We request that ammonia nitrogen be eliminated from our sampling requirements. This facility does not disinfect by chloramination, therefore we feel sampling for this parameter is unnecessary.

Solids are generated by manual sludge removal from sedimentation basins, backwashing filters, and filter -to -waste after filter backwashes are completed. Solids produced from filter backwashes and filter -to -waste is routed to a waste pump station and is then pumped to the head of the water treatment process. Solids removed from the sedimentation basins are routed directly to one of three residual lagoons. Permits and Classifications: 1. The discharge from the residuals lagoons is authorized by NPDES Permit NC0086011. The classification for the discharge is Grade 1 Physical/Chemical. Operation: 1. The system consists of a waste station with (3) Fairbanks Morse single stage pumps rated at 6.48 MGD each, (2) Fairbanks Morse basin sludge pumps rated at 1.0 MGD each, (2) lagoon pumps rated at 0.65 MGD each and (3) residuals lagoons (2 lagoons at 1.47 MG and 1 lagoon at -2.0 MG). Each residuals lagoon consists of an oval earthen lagoon with clay bottom. 2. Backwash and filter to waste water from the plant process flows to the waste station and then is pumped by the waste station pumps to raw water reservoir #2 at the head of the plant treatment process. 3. All sedimentation basin and hopper blow downs are pumped by the basin sludge pumps directly to one of three residuals lagoons. 4. The solids stream enters on one end of each lagoon and the decant is pumped from the opposite end by the lagoon pumps to the waste station where it is returned to the head of the treatment process. 5. Residuals lagoons are rotated with one cleaned and ready for use, one in service and one drying at all times. 6. Residuals are removed from the lagoons and hauled to an application site which consists of -31 acres on Cooper Road (about 1.0 mile from the Neilson WTP) by a private contractor. 7. Once the sludge has dried it is spread and a grass cover planted to stabilize the area. Application Requirements: 1. Bulk residuals are not applied under the following conditions: i. If the residuals are likely to adversely affect a threatened or endangered species. ii. If the application causes prolonged nuisance conditions. iii. If the land fails to assimilate the bulk residuals or the application causes the contravention of surface water or groundwater standards. Neilson Water Treatment Plant Solids Handling Plan Revised 12/5/2008 1 iv. If the land is flooded, frozen, or snow-covered or is otherwise in a condition such that runoff of the residuals would occur. v. During a precipitation event or within 24 hours following a rainfall event of 0.5 inches or greater in a 24-hour period. vi. For residuals treatment and storage facilities, the following minimum setbacks shall be adhered to: Description of Setback Minimum Setback (feet) Habitable residence or place of public assembly under separate ownership or not to be maintained as part of the project site 100 Property lines 50 Private or public water supply 100 Surface waters (streams, -intermittent and perennial, perennial water bodies, and wetlands) 50 Wells with exception to monitoring wells 100 2. When land applying bulk residuals to application site, the following minimum setbacks are maintained at all times: Setback By Type of Residual (feet) Description of Setback Liquid Cake Private or public water supply 100 100 Surface waters (streams -intermittent and perennial, perennial water bodies, and wetlands) 100 25 Surface water diversions (ephemeral streams, waterways, ditches) 25 0 Groundwater lowering ditches (where bottom of The ditch intersects SHWT) 25 0 Subsurface groundwater lowering system Wells with exception to monitoring wells 100 100 Bedrock outcrops 25 0 3. Specific bulk residuals land application area boundaries are clearly marked on each land application site prior to and during a residuals land application event. Spills and Noncompliance Notification: 1. The Winston-Salem Regional Office, telephone number (336) 771-5000 will be notified within 24 hours or the next working day following the occurrence or first knowledge of the occurrence of any of the following: i. Any occurrence with the distribution program which results in the land application of significant amounts of wastes which are abnormal in quantity or characteristic. Neilson Water Treatment Plant Solids Handling Plan Revised 12/5/2008 2 ii. Any failure of the distribution program resulting in a release of materials to receiving waters. iii. Any process unit failure, due to known or unknown reasons, that render the facility incapable of adequate residual treatment. 2. Persons reporting such occurrences by telephone shall also file a written report in letter form within (5) days following first knowledge of the occurrence. This report must outline the actions taken or proposed to be taken to ensure that the problem does not recur. 3.
