IN SITU REMEDIATION (15A NCAC 02C .0225) or TRACER WELLS (15A NCAC 02C .02291: 1) Passive Injection Systems - In -well delivery systems to diffuse injectants into the subsurface. Examples include ORC socks, iSOC systems, and other gas infusion methods (Note: Injection Event Records (IER) do not need to be submitted for replacement of each sock used in ORC systems). 2) Small -Scale Injection Operations — Injection wells located within a land surface area not to exceed 10,000 square feet for the purpose of soil or groundwater remediation or tracer tests. An individual permit shall be required for test or treatment areas exceeding 10,000 square feet. 3) Pilot Tests - Preliminary studies conducted for the purpose of evaluating the technical feasibility of a remediation strategy in order to develop a full scale remediation plan for future implementation, and where the surface area of the injection zone wells is located within an area that does not exceed five percent of the land surface above the known extent of groundwater contamination. An individual permit shall be required to conduct more than one pilot test on any separate groundwater contaminant plume. 4) Air Injection Wells - Used to inject ambient air to enhance in -situ treatment of soil or groundwater. 5) In -Situ Thermal Wells (IST) — Used to `heat' contaminated groundwater to enhance remediation.
