Russotto: In accordance with your permit application received March 1, 2004, and subsequent additional information received April 1, 2004 and April 22, 2004 we are forwarding herewith Permit No. WQ0023634, dated May 17, 2004, to VOC, LLC for the construction and operation of the subject wastewater treatment and surface irrigation facilities. This permit shall be effective from the date of issuance until April 30, 2009, and shall be subject to the conditions and limitations as specified therein. Please pay particular attention to the monitoring requirements in this permit. Failure to establish an adequate system for collecting and maintaining the required operational information will result in future compliance problems. The Division is concerned with the migration of nitrates from the Walnut Island LLP facility to the groundwater drainage system (installed as part of this permit). If this facility is found to contribute to that migration, the facility will be required to take corrective actions. It is suggested that the permittee continue discussions with Walnut Island on merging the two systems. If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of this permit. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, NC 27699- 6714.

Classification of Subsurface Water Pollution Control Systems: Systems which utilize the soil for subsurface treatment and disposal of wastewater and/or are required to have a certified operator under 15A NCAC 18A.1961. *** *** Any subsurface system that has as part of its treatment process a water pollution control systems that may be classifiers under Rules .0302 through .0307 of this section shall be subject to addional classification. Classification of Biological Water Pollution Control Treatment Systems: Grade I Biological WPCS Septic tank/sand filter systems - Biological lagoon systems - Constructed wetlands and associated appurtenances ZGrade II Biological WPCS - Systems that utilize an activated sludge or fixed growth process with a permitted flow less than or equal to 0.5 milIon gallons per day (mgd) Grade III Biological WPCS - Systems that utilize an activated sludge or fixed growth process with a permitted flow of greater than 0.5 through 2.5 million gallons per day .(mgd) Grade II systems that are required to achieve biological nutrient reduction Grade lV Biological WPCS - Systems that utilizing an activated sludge or fixed growth process with a permitted flow of greater than 2.5 million gallons per day (mgd) - Grade III systems that are required to achieve biological nutrient reduction * Biological Nutrient Reduction - The reduction of total nitrogen or total phosphorous by an activated sludge or fixed growth process as required by the facilities permit. Classification of Collection Water Pollution Control Systems: (whichever provides lowest grade) Sam grade as biological water pollution control system. Grade of system: Based on population served: 1,500 or Less = Grade I 1,501 to 15,000 = Grade II 15,001 to 50,000 =. Grade III 50,001 or more = Grade IV Definitions Activated Sludge - shall mean a biological wastewater treatment process in which predominantly biodegradable polluntants in wastewater are absorbed, or adsorbed by living aerobic organisms and bacteria. Chemical Process - shall mean a wastewater pollution control system process consisting exclusively of the addition of chemicals to treat wastewater. Collection System - shalI mean a continuous connections of pipelines, conduits, pumping stations, and other related constructions used to conduct wastewater to the water pollution control system. Electrodialysis System - shall mean a system utlizing a selective separation of dissolved solids process that is based on electrical charge and diffusion through a semipermeable membrane. Physical Process - shall mean any water pollution control system process consisting of electrodialysis, adsorption, absorption, air stripping, gravimetric sedimentation, floation, and filtration as a means of treatment. Reverse Osmosis System - shall mean a system which utilizes solutions and semipermable membranes to separate and treat wastewater. Ultrafiltration System - shall mean a system which utilizes a membrane filter to remove pollutants from wastewater. Water Pollution Control System - shall mean any system for the collection, treatment, or disposal of wastewater and is classified under the provision of G.S. 90A-37. Note: Please refer to G.S. 90A-37 for additioiwl information and definitions.
