We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.
Problems/Comments
Ordnance or ordnance-related problems. The Zeto Point Minefield is located northeast of downtown Adak near the tip of Zeto Point. The Zeto Point Minefield was intrusively investigated in 1998 along with 12 other proposed minefield locations outside of the urban area on Adak. Although the location for the minefield presented in the training memorandum was inexact, it was possible to identify the most likely location in the field based upon the terrain and professional knowledge of military defensive tactics. The location selected for survey paralleled a relatively accessible beach area which fronted rolling hills. The area covered is the most accessible and logical route away from the beach. Only three metallic anomalies were investigated along the Zeto Point survey lane. These anomalies consisted of a piece of wire, a nail, and an unknown anomaly (i.e., a site excavated to a depth of 12 inches without contacting any physical target). No mines or OE waste were found at this site. NOFA selected in the OU B-1 ROD. Draft Close Out Report for Partial Delisting submitted for Department review on June 16. Comments were submitted to the Navy on August 16.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 4/15/2000 | Site Added to Database | Ordnance or ordnance-related problems. | Elim Yoon |
| 4/15/2000 | Update or Other Action | The Level I Screen is a framework intended to facilitate somewhat objective evaluation of subjective issues and information. The screen considers the ordnance characteristics of the site (i.e., type of ordnance and density) along with physical characteristics of the site (i.e., terrain and vegetation) to determine the qualitative risk associated and the general category of future action that may be needed at the site to minimize that risk (i.e., additional investigation, remedial action, or no action). The screen also incorporates evaluation of the strength of evidence upon which screening decisions are made to ensure that there is reasonable supporting data for the choices made at this stage of the process. | Elim Yoon |

| 12/28/2001 | Institutional Control Record Established | Institutional Control Established. Includes: Requirements for Inspections and Reporting, requirements for Education Program, and requirements for Sign Inspections. See document “Adak Island Institutional Control Management Plan, Final Edition, December 2001, Prepared by: Engineering Field Activity, Northwest.” | Elim Yoon |
| 8/31/2004 | Conditional Closure Approved | NOFA selected in OU-B1 ROD; Ordnance Awareness Program IC in place. | Jason Weigle |
| 10/19/2004 | GIS Position Updated | Latitude and Longitude was derived using ArcGIS with either High Resolution Aerial Photography from the Navy with an up to 3 meters error, or line maps used in investigations combined with road layers, +/-25 feet accuracy. Metadata is as follows: Updated NAD 1983 State Plane Alaska 10 FIPS 5010 Feet; Projection: Lambert Conformal Conic; False Easting: 3280833.333333; False Northing: 0.000000; Central Meridian: -176.000000; Standard Parallel 1: 51.833333; Standard Parallel 2: 53.833333; Latitude of Origin: 51.000000; GCS North American 1983. | Jason Weigle |
| 3/7/2005 | Update or Other Action | Added MRTS data, derived from ADNR and USGS range, township, and section data overlaid on lat/lon coordinates derived previously. Accuracy is equivalent to the lat/lon coordinates. MRTS information depicts the center point of range fans and target areas; actual target areas or fans may overlap several sections. | Jason Weigle |
| 6/16/2005 | Update or Other Action | Draft Close Out Report for Partial Delisting submitted for review on this date. | Jason Weigle |
| 8/16/2005 | Update or Other Action | Comments on Draft Close Out Report for Partial Delisting submitted to Navy on this date. | Jason Weigle |
| 4/5/2006 | Update or Other Action | File number 2501.38.005 assigned on this date. | Jason Weigle |
| 3/11/2024 | ANCSA Program Eligible | This site meets the criteria for the EPA Contaminated ANCSA Lands program: the site is on ANCSA conveyed land, the contamination occurred pre-ANCSA conveyance, and there is documented proof of contamination that exceeds DEC’s cleanup values in 18 AAC 75. This site will be listed as “verified” on EPA’s contaminated lands inventory. | Brittani Mack |
