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: 2/14 , 20_23_ 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.

I. J. K. 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. 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: This site has a gasoline UST release incident. It is regulated by the NCDWM-UST who has approved the operation of an air sparge and SVE remediation system that has been active since April of 2015. Recently, the NCDWM-UST has approved the use of Oxygen Biochem as a passive pour of the injectant into recovery wells RW3 and RW4 that are not remediating as quick as desired. Semi-annual groundwater monitoring for VOCs is ongoing. Terraquest will pour a 40 pound OBC to 20 gallon water mixture into each of RW3 and RW4 on a monthly basis for four months or as needed. WELL CONSTRUCTION DATA (1) No. of injection wells: Proposed 2 Existing (provide NC Well Construction Record (GW-1) for each well) (2) Appx. injection depths (BLS): 29-50 feet BGS based on recent groundwater location (3) For Proposed wells or Existing wells not having GW-1s, 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 INJECTION SUMMARY NOTE: Only injectants approved by the epidemiology section of the NC Division ofPublic Health, Department of Health and Human Services can be injected. Approved injectants can be found online at http:Hdeg.nc. gov/about/divisions/water-resources/water-resources-permits/wastewater-branch/ground-water- protection/ground-water-approved-injectants. All other substances must be reviewed by the DHHS prior to use. Contact the UIC Program for more info iyou wish to het approval for a different additive.
