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 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 Print Clearly or Type Information. Illegible Submittals Will Be Returned as Incomplete. DATE: August 19 , 20_20_ PERMIT NO. (to be filled in by DWR) NOTE- If this NOI is being submitted as notification of a modification of a previously issued NOI for this site (e.g., different injection wells, plume, additives, etc.) and still meets the deemed permitted by rule criteria, provide the previously assigned permit tracking number and any needed relevant information to assess and approve injection: Permit No. Issued Date: A.

INJECTION ZONE MAPS — Attach the following to the notification. (1) Contaminant plume map(s) with isoconcentration lines that show the horizontal extent of the contaminant plume in soil and groundwater, existing and proposed monitoring wells, and existing and proposed injection wells; and (2) Cross-section(s) to the known or projected depth of contamination that show the horizontal and vertical extent of the contaminant plume in soil and groundwater, changes in lithology, existing and proposed monitoring wells, and existing and proposed injection wells. (3) Potentiometric surface map(s) indicating the rate and direction of groundwater movement, plus existing and proposed wells. See Figures I through 8 for site location, injection zone maps, and cross sections. I. DESCRIPTION OF PROPOSED INJECTION ACTIVITIES AT THE SITE — Provide a brief narrative regarding the cause of the contamination, and purpose, scope, goals of the proposed injection activity: ATC will install Provectus Oxygen Releasing Substrate (ORS) sleeves in monitoring wells DW-I, DW-3, and DW-4 in order to aide in natural attenuation and reduce compounds concentrations to below the North Carolina Groundwater Quality Standards (2L Standards). Based on the most recent samplingevent in March 2019, several compounds exceeding 2L Standards were detected in DW-1, DW-3, and DW-4. The socks come in 3-foot sections. ATC will install two 3-foot sections at the base of the wells, across the well screens. The socks will release oxidizing compounds into the groundwater for approximately 6 months, at which point the chemicals in the socks will have depleted. ATC will also measure dissolved oxygen, conductivity, temperature, pH, and oxygen reduction potential in monitoring wells DW-1, DW-3, and DW-4 during the October 2020 sampling event. ATC will change the ORS sleeves periodically as determined by the laboratory results. J. WELL CONSTRUCTION DATA (1) No. of injection wells: 0 Proposed 3 Existing (provide NC Well Construction Record (GW-1) for each well) — See Appendix A (2) Appx. injection depths (BLS): 24 feet (3) For Proposed wells or Existing wells not having GW-ls, provide well construction details for each injection well in a diagram or table format. A single diagram or line in a table can be used for multiple wells with the same construction details. Well construction details shall include the following (indicate if construction is proposed or as -built): (a) Well type as permanent, Geoprobe/DPT, or subsurface distribution infiltration gallery (b) Depth below land surface of casing, each grout type and depth, screen, and sand pack (c) Well contractor name and certification number K. INJECTION SUMMARY NOTE: Only injectants approved by the epidemioloy section of the NC Division of Public Health, Department of Health and Human Services can be injected. Approved injectants can be found online at hlt 2:Hdeg.nc.gov/about/divisions/water-resources/water-resources-permits/wastewater-branch/ground-watgr- protection/ground-water-approved-injectants. All other substances must be reviewed by the DHHS prior to use. Contact the UIC Program for more info if you wish to get approval for a deferent additive. However, please note it may take 3 months or loner. Deemed Permitted GW Remediation NOI Rev. 2-14-2020 Page 3 Injectant: Provectus-ORS Total Atnt. to be injected (gal)/event: Amt.

FIRE FIGHTING MEASURE Flash Point • Not applicable Flammability • Not applicable Ignition Temperature • Not applicable Danger of Explosion • Non -explosive Extinguishing Media • Water Fire Hazards • Oxidizer. Storage vessels involved in a fire may vent gas or rupture due to internal pressure. Damp material may decompose exothermically and ignite combustibles. Oxygen release due to exothermic decomposition may support combustion. May ignite other combustible materials. Avoid contact with incompatible materials such as heavy metals, reducing agents, acids, bases, Provectus ENVIRONMENTAL PRODUCTS} MATERIAL SAFETY DATA SHEET: PROVECT-ORS Page: 3 of 5 combustible (wood, papers, cloths etc.) Thermal decomposition releases oxygen and heat. Pressure bursts may occur due to gas evolution. Pressurization if confined when heated or decomposing. Containers may burst violently. Fire Fighting Measures • Evacuate all non -essential personnel • Wear protective clothing and self-contained breathing apparatus. • Remain upwind of fire to avoid hazardous vapors and decomposition products. • Use water spray to cool fire- exposed containers. 7. ACCIDENTAL RELEASE MEASURES Spill Clean-up Procedure • Oxidizer. Eliminate all sources of ignition. Evacuate unprotected personnel from equipment recommendations found in Section 9. Never exceed any occupational exposure limit. • Shovel or sweep material into plastic bags or vented containers for disposal. Do not return spilled or contaminated material to inventory. Avoid making dust. • Flush remaining area with water to remove trace residue and dispose of properly. Avoid direct discharge to sewers and surface waters. Notify authorities if entry occurs. • Do not touch or walk through spilled material. Keep away from combustibles (wood, paper, oils, etc.). Do not return product to container because of risk of contamination. 8. HANDLING AND STORAGE Storage • Oxidizer. Store in a cool, well -ventilated area away from all source of ignition and out of direct sunlight. Store in a dry location away from heat. • Keep away from incompatible materials.
