Sincerely, CES of NC, PLLC -If Aaron Williamson Project Manager Enclosure North Carolina Department of Environmental Quality — Division of Water Resources NOTIFICATION OF INTENT (NOI) TO CONSTRUCT OR OPERATE INJECTION WELLS The following are `permitted by rule" and do not require an individual permit when constructed in accordance with the rules of 15A NCAC 02C.0200 (NOTE: This form must be received at least 14 DAYS prior to injection) AQUIFER TEST WELLS (15A NCAC 02C .0220) These wells are used to inject uncontaminated fluid into an aquifer to determine aquifer hydraulic characteristics. IN SITU REMEDIATION (15A NCAC 02C .02251 or TRACER WELLS (15A NCAC 02C .0229): 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 are 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.

Avoid inhalation of dust and contact with skin and eyes. Do protective equipment and not touch damaged containers or spilled material unless wearing appropriate protective clothing. emergency procedures Wear protective clothing as described in Section 8 of this safety data sheet. Local authorities should be advised if significant spillages cannot be contained. Methods and materials for Keep combustibles (wood, paper, oil, etc.) away from spilled material. Should not be released into containment and cleaning up the environment. This product is miscible in water. Stop leak if possible without any risk. Dike the spilled material, where this is possible. Never return spills in original containers for re -use. For waste disposal, see Section 13 of the SIDS Environmental precautions Do not allow to enter drains, sewers or watercourses. Contact local authorities in case of spillage to drain/aquatic environment. 7. Handling and storage Precautions for safe handling Take any precaution to avoid mixing with combustibles. Keep away from clothing and other combustible materials. Do not get this material in your eyes, on your skin, or on your clothing. Do not breathe dust or mist or vapor of the solution.
