If the TOC concentration as measured in the background monitor well exceeds 10 mg/l, this concentration will be taken to represent the naturally occurring TOC concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above. 7. Monitoring wells shall be reported consistent with the nomenclature and location information provided in the submitted site map as required by Condition I.6. and this attachment.

Systems other than those listed above shall be subject to additional classification. Classification of Land Application of Residuals Systems: Systems permitted and dedicated for land application of residuals that are produced by a water pollution control system or contaminated soils. Classification of Physical/Chemical Water Pollution Control Treatment Systems: Grade I Physical/Chemical: Any water pollution control system that utilizes a primarily physical process to treat wastewater. This classification includes groundwater remediation systems. ** Grade H Physical/Chemical: Any water pollution control system that utilizes a primarily chemical process to treat wastewater. This classification includes reverse osmosis, electrodialysis, and ultrafiltration systems_ ** ** Any water pollution control system that utilizes a phyicallchemical process to enhance an activated sludge or feed growth process, shall not be subject to additional classification. 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 classified under Rules .0302 through .0307 of this section shall be subject to addional classification. IDefniitions 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 - shall 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 additional information and definitions.
