Problems/Comments
A discharge/release of petroleum was discovered through soil sampling results in connection with a DoD-funded NALEMP program site investigation in July 2013 on behalf of the Native Village of Tetlin. The site is located on Tetlin Native Corporation land on the south side of the Alaska Highway between the highway and Midway Lake, southeast of the Midway Lake turnout. The release is likely from deteriorated 55-gallon drums, vehicle equipment and parts possibly connected to construction of the CANOL Pipeline in the 1940s. Future action under NALEMP is currently underway through the direction of the Tetlin Village Council.

|---|---|---|---|
| 10/24/2013 | Site Added to Database | A new site has been added to the database | Mitzi Read |
| 12/8/2015 | Update or Other Action | Site management changed from Howard to Carnahan. | John Carnahan |
| 4/14/2016 | Document, Report, or Work plan Review - other | Provide comments on debris removal and limited site investigation reporting. | John Carnahan |
| 6/6/2016 | Site Characterization Report Approved | DEC Approval for Removal Action Report, Midway Lake and Midway Lake North Sites, May 2016 – Revision 1. The limited sampling program resulted in the following conclusions: (1) Diesel range organics (DRO) and residual range organics (RRO) were identified above the DEC’s migration to groundwater cleanup level in select areas; (2) Lead was identified in soil beneath a broken battery and requires small scale cleanup, and could be indicative of additional releases; (3) Metals were identified a several locations that are hypothesized to be background levels at most locations; and (4) Limited sediment and surface water testing did not indicated substantial impacts in sampled locations. Future work is proposed. | John Carnahan |

| 3/15/2022 | Site Characterization Report Approved | Debris Removal and Geophysical Investigation Report approved. Report details debris removal and geophysical investigation activities conducted in 2021 at the Porcupine Creek and Jerry Hill sites. | Kelly Walker |
| 10/11/2022 | Document, Report, or Work plan Review - other | Review completed for Pipeline Test Pit Investigation Report for the Jerry Hill Site along the Alaska Highway. This report detailed the excavation of test pits and analytical sampling of soils surrounding abandoned underground piping, likely related to the CANOL or Haines-Fairbanks Pipelines. Analytical samples showed no detections of contaminants above ADEC's Method Two Migration to Groundwater Soil Cleanup Levels. Review was limited on this document as no contamination has been documented at this location. | Kelly Walker |
| 3/17/2023 | Risk Assessment Workplan Approved | DEC reviewed and approved the "Debris Removal Work Plan" for the Alaska Highway and Jerry Hill and 40-Mile Dump-East sites. This work plan details the planned debris removal and possible soil sampling at former known dump sites created during and after construction of the Alaska Highway and the CANOL Pipeline. | Kelly Walker |
| 12/21/2023 | Site Characterization Report Approved | DEC reviewed and approved the "Debris Removal Report" for the Alaska Highway Jerry Hill and 40-Mile Dump-East sites. This report detailed the surface and subsurface debris removal and soil sampling conducted at former dump sites created during and after construction of the Alaska Highway and the CANOL Pipeline. Additional investigation of subsurface steel piping associated with the Alaska Highway and CANOL Pipeline sites are recommended. | Kelly Walker |
