NO. UTD 009 086 133 RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) CORRECTIVE ACTION ACTIVITIES SECOND SEMI-ANNUAL REPORT 2024 Dear Mr. Hansen: In accordance with the requirements of the above referenced Permit, as reissued May 14, 2004 and updated on January 26, 2010, the status of each major area of Permit activity is provided below for activities performed during the first half (January through June) of 2024 and those planned for the second half of 2024. This report is submitted on behalf of United States Steel Corporation (USS) and Anderson Geneva, LLC (Geneva). Corrective Action Management Unit Activities Completed The revised Draft CAMU Post-Closure Care Plan was resubmitted on April 19, 2022 and USS/Geneva are working with UDEQ to finalize. On August 7, 2023, USS/Geneva provided informal comments to UDEQ on the draft permit modules, along with relevant attachments. UDEQ provided responses and updated permit modules to USS/Geneva on November 2, 2023. Additional discussion on the permit modules was included in a meeting at UDEQ on November 16, 2023. Comments on the most recent draft permit modules were provided to UDEQ on June 24, 2024. Updates to the draft Groundwater Monitoring Plan are in progress and will be submitted to UDEQ in the second half of 2024. The following operation, maintenance, and monitoring activities were performed in the first half of 2024:  Formal inspections of the CAMU on March 27, 2024 and June 21, 2024.  CAMU leachate treatment events in March, April, May, and June 2024. A total of 35,170 gallons of leachate were treated in the first half of 2024. RCRA Semi-Annual Report July 15, 2024 Page 2 Corrective Action Management Unit Activities Planned for Second Half of 2024 The following operation, maintenance, and monitoring activities are planned for the second half of 2024:  Perform formal inspections of the CAMU in 3rd Quarter and 4th Quarter, and as needed for any substantial events.  Perform CAMU leachate treatment events (as needed).  Submit the updated CAMU Post-Closure Groundwater Monitoring Plan and Post- Closure Care Plan.  Begin to implement the Groundwater Monitoring Plan when approved. Semi-Annual Status of Verification Activities at Solid Waste Management Unit (SWMU) BF-26B Characterization samples were collected of the potential backfill material located in the footprint of BF-26B, referred to as Area 6, during the second half of 2022 and the LROF, presenting the results and risk evaluation, were submitted on June 14, 2024. Material Management Area No additional material has been added or moved from the OR-21C/22A material within the Material Management Area (MMA) on the east side of the Site (described in the January 2021 Semi-Annual Report). Table 1 attached to this letter presents the volume of material in the MMA. Other Resource Conservation and Recovery Act (RCRA) Corrective Action Activities Completed Table 2 attached to this letter summarizes documents sent to UDEQ during the first half of 2024. This table also includes documents that may have been approved during the first half of 2024 and/or other actions being taken. Also included in Table 2 are documents from previous time periods where actions are pending. Corrective action activities that occurred during the first half of 2024 and that are not addressed in the sections above, are summarized below:  Completed groundwater monitoring at the following SWMUs, in accordance with the respective approved SMPs: SWMU GW-4.2, Oil Reclamation Area; SWMU 4.6, Maintenance Area; SWMU GW-4.8, Nitrogen West Area; SWMU GW-4.11, Front End Oil Tanks South Area; SWMU 4.13, Highline Area; and SWMU GW-4.14, Former CHWIs.  Completed light non-aqueous phase liquid (LNAPL) gauging at SWMU GW-4.9, Rolling Mill Clarifier Area in accordance with the approved SMP.  Submitted the LROF for the biosparge pilot testing at SWMU GW-4.1A Benzol Plant Area East. RCRA Semi-Annual Report July 15, 2024 Page 3  Abandoned 7 monitoring wells, 16 piezometers, and 8 recovery wells at various SWMUs across the site and submitted a status letter detailing the work.  Abandoned and re-installed two damaged monitoring wells at SWMU GW-4.2.  Began the Corrective Action Plan and Design of a full-scale biosparge system for SWMU GW-4.1A Benzol Plant Area East.  Discovered discrete areas of tarry materials during regrading efforts that are a part of BF-38 materials. Segregated the materials and began looking at off-site disposal options. Other RCRA Corrective Action Activities Planned for the Second Half of 2024 Planned activities for the second half of 2024 will consist of SMP groundwater monitoring and reporting and product gauging (associated with SMP sampling). Work will continue at the remaining groundwater SWMUs, with NLs to be provided detailing any proposed work. If other specific actions are required, they will be proposed in NLs. Activities in approved NLs will continue. Letter Reports of Findings, Status Letters, and Human Health Risk Evaluation reports will be submitted as necessary. Specific activities planned for the second half of 2024, not addressed in the sections above are:  Complete required sampling events, in accordance with the respective approved SMPs, at the following SWMUs: SWMU GW-4.2, Oil Reclamation Area; SWMU GW-4.6, Maintenance Area; SWMU GW-4.8, Nitrogen West Area; SMWU GW-4.9, Rolling Mill Clarifier Area; SWMU GW-4.11, Front End Oil Tank South Area; SWMU 4.13, Highline Area; and SWMU GW-4.14, Former CHWIs.  Complete and submit the Corrective Action Plan and Design for the full-scale biosparge system for SWMU GW-4.1A Benzol Plant Area East.  Submit a LROF/HHRE for SP-14A and SP-14B.  Continue to complete other SMPs and ECs as land use plans solidify.  Review other SWMUs not yet at Corrective Action Complete status (e.g., SI-4, OH-4, and others) and begin to assess options to move them towards Corrective Action Complete status.  Address additional BF-38 material discovered during regrading. Site-Wide SWMU Status Figure 1 presents a status of SWMUs at the site, as of June 30, 2024, as well as the currently anticipated Site Management Plan (SMP) areas. It should be noted that the anticipated SMP areas shown on Figure 1 are currently under development and are subject to change; they are included here for informational purposes only. Additionally, property ownership shown may be slightly outdated and will be updated as changes are finalized and become available. SMPs will be developed for SWMUs with CACWC status. The SMPs will be formally submitted to UDEQ under separate cover as they are developed. Table 3 presents the updated Tier 1 and 2 SWMU list as of June 30, 2024.
