Klimek, P.E., Director Division of Water Quality January 20; 2006 Ms. Elizabeth Martin DAK Americas 3500 Daniels Rd., N.E. • Leland, North Carolina 28451 a VAN 2 7 2006 O WWQ Subject: NPDES Permit Modification Permit No. NC0003719 DAK Resins - Cedar Creek Cumberland County Dear Ms. Martin: The Division has reviewed your request for a permit modification at the DAK Resin Cedar Creek site facility. The modification consists of the rerouting of the non -contact cooling water from the wastewater treatment plant influent to the storinwater system discharging through outfall 001. The permit has been.modified to allow the discharge of the non -contact cooling water through outfall 001. The supplement to the permit cover sheet and the monitoring - requirements for outfall 001 were modified. The monitoring requirements reflect the requirements for the cooling water discharge commingled with .stormwater. Due to this permit modification permit sections A (9.) through A (12.) include changes from your existing permit. Enclosed fmd the supplement to permit cover sheet describing the wastewaters tributary to outfall 001 and the pages containing Sections A (9.) through A (12.) Please replace these pages in your current permit. A letter shall be submitted to the Division when the modification is completed. If you have any questions concerning the draft permit or the otherrequirements for your facility, please call me at (919) 73375083, extension 553. Sincerely,.

Continue to operate an existing 1.25 MGD wastewater treatment facility consisting • of flow!equslization, 'spill bain, pH adjustment, oil skimming; comrninute; dual aeration basins; clarifier, parshall flume, sludge pump station, dual aerobic digesters, aerated biosolids holding basin, biosolids drying beds and other associated equipment located at DAK Resins, LLC, on NC Highway 53, south of • Fayetteville in Cumberland County. 2. Upon closure and clean-up of the Monsanto RounclUp plant,: continue to operate an. existing 1.25 MGD wastewater treatment facility"with a permitted discharge of 0.5,MQD consisting of flow equAli7ation, spill basin, pH adjustment, oil skimming, comminute, dual aeration :basins, clarifier, parshall flume, sludge pump station, dual aerobic digesters, aerated biosolids holding basin, biosolids drying beds and other associated eqUipment,located at DAK Resins, LLC, Fayetteville Plant, on NC Highway 53, south of Fayetteville in Cumberland Cs:iiinty. 3. Discharge water from said treatment works at the location specified on the attached map into the Cape Fear River which is classified C waters in the Cape Fear River Basin 4. Upon sale of the Monsanto Fayetteville facility, the new owner shall request a modification to the NPDES permit and complete a new application for discharge in accordance with special condition A. (5.) for an ultimate permitted flow of 1.25 . MGD. • 5. Discharge non -contact cooling water and stormwater from the outfall specified on • the attached map (and stormwater from other outfalls specified in the July,31, 1992 stormwater permit application) into the Cape Fear River which is classified C waters in the Cape Fear River Basin. Any other point source discharge to surface waters of the stateris prohibited unless covered by another permit, authorization or approval. , This permit does not relieve the permittee from -responsibility for compliance • with any other applicable federal, state, or local law, rule, standard, ordinance, ' order, judgement or decree. Permit NC0003719 A. (9.) EFFLUENT LIMITATIONS AND MONITORING REQIREMENTS During the period beginning on the effective date of the permit and lasting until connection of the non -contact cooling water to outfall 001, the Permittee is authorized to discharge stormwater from outfall 001' Such discharges shall be limited and monitored by the permittee as specified below: STORMWATER DISCHARGE `;: i'' " „rk ,,Cr ...

Cutoff Concentration. For each parameter, the arithmetic mean of all analytical sampling results collected during the first year of the permit shall be calculated for each individual outfall and compared to the cut-off concentrations listed. If the arithmetic mean is below the specified cut-off concentration for a given parameter, then the facility is not required to continue annual analytical monitoring for that parameter at the outfall during the term of the permit unless a significant change in facility operations or configuration occurs. If cut-off concentration results in discontinued analytical monitoring at an individual discharge outfall, the permittee is required to maintain facility operations that ensure the continuation of stormwater runoff quality. 2. Measurement frequency. Once per year. The facility must perform analytical sampling during the first full year and last year of the permit term regardless of cut-off concentration conditions. Analytical results from sampling during the final year of the permit term must be submitted with the permit renewal application. Failure to monitor storm events in accordance with the specified frequency shall constitute a violation of this permit. 3. Sample Location. Samples to be collected at each stormwater discharge outfall (SW-1) located north of the river water intake pump overflow and south of the sludge drying beds. 4. For each sampled representative storm event the total precipitation, storm duration, and total flow must be monitored. Total flow shall be either: (a) measured continuously, (b) calculated based on the amount of area draining to the outfall, the amount of build -upon (impervious) area, and the total amount of rainfall, or (c) estimated by the measurement of flow at 20 minute intervals during the rainfall event (not to exceed three hours). For purposes of the stormwater sampling required in. this permit, all samples shall be collected from a discharge resulting from a representative storm event (See Parts A. (13) and A. (14.)). . Permit NC0003719 A. (10.) EFFLUENT LIMITATIONS AND MONITORING REQIREMENTS During the period beginning upon connection of the cooling water to outfall 001 and lasting until expiration, the Permittee is authorized to discharge non -contact cooling water and stormwater from outfall 001.

Monitoring requirements and limit only apply if chlorine is added to the system. 4. The pH shall not be less than 6.0 standard units nor greater than 9.0 standard units. A. (11.) STORMWATER MONITORING REQUIREMENTS/ Qualitative Monitoring Qualitative monitoring requires a qualitative inspection of each stormwater outfall, regardless of representative outfall status, for the purpose of evaluating the effectiveness of the Stormwater Pollution Prevention Plan and assessing new sources of stormwater pollution. No analytical tests are required. Qualitative monitoring of stormwater outfall does not need to be performed during a representative storm event. __ y' y - : ' :Stormwater: Discharge Characteristics_,�'�h��..,,4a:��, � .ti, = 'Measuremenffre uenc`?= :, _ ' Sam le�Locat on'k 'x _ p Color • 'Semi -Annual - See Note 2 Odor • Semi -Annual See Note 2 Clarity Semi -Annual See Note 2 Floating Solids Semi -Annual See Note 2 Suspended Solids Semi -Annual See Note 2 Foam Semi -Annual See Note 2 Oil Sheen Semi -Annual See Note 2 Other obvious indicators of stormwater pollution Semi -Annual See Note 2 Notes: 1. Measurement Frequency. The first qualitative monitoring event during the term of the permit must be performed during the initial analytical monitoring event. All subsequent qualitative monitoring will be performed twice per year, once in the spring (April - June) and once in the fall (September - November). 2. Sample Location: Until connection of the non -contact cooling water to outfall 001 visual monitoring shall be performed at the manhole located north of the river water intake pump overflow and south of the sludge drying beds. Upon connection of the non -contact cooling water to outfall 001 visual monitoring may be performed at each stormwater discharge outfall (SDO) at a point where no additional significant materials could reasonably enter the system as a result of facility operations.
