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. |

CERCLA FS |
Submitted approval letter to the Navy for the Final OUB-2 Feasibility Study. ALSW-01 is included in Remedial Action Area #5 in the FS. The FS identifies the "Navy's preferred remedy" for the site as annual beach sweeps and site specific LUCs. These LUC's are required to prevent human contact with MEC present at the site and the Navy will retain ownership of this site throughout the period required to verify that no more munitions are washing up on the shore. The FS presents the Navy's preferred remedy and this may be adjusted based on EPA, ADEC, and community input during the Proposed Plan and development of the Record of Decision. |

CERCLA Remedial Design/Remedial Action Plan Approved |
Submit approval letter for OUB-2 Non-Time Critical Removal Action (NTCRA) work plan and Quality Assurance Surveillance Plan (QASP). The plan address’s all five Remedial Action Areas identified if the RI as requiring remediation. At RAA-05 (which includes ALSW-01) the NTCRA will include performing monthly surface sweeps along the seawall to better characterize the occurrence of MEC. It is hoped that the NTCRA being implemented at ALDA-01 will significantly reduce the occurrence of MEC on the seawall. The NTCRA is scheduled to begin in April 2013, weather permitting. |

CERCLA Remedial Action Completion Report |
This report documents APTIM’s results for the 2018 season. The scope of this work was to remove MEC and/or material potentially presenting an explosive hazard (MPPEH) from areas within the RAA-01 (open burn/open detonation) and RAA-03W (remaining grids adjacent to RAA-01) and the RAA-05 Andrew Lake Disposal Area (ALDA). MEC/MPPEH were removed by conducting excavations of metal saturated areas, removal of discrete digital geophysical mapped (DGM) anomalies via hand digging
assisted by mini excavators, and mag and dig in a small number of areas outside the DGM survey area (step out areas). For metallic saturated areas, APTIM used armored, long-reach excavators to remove material and spread it into lifts, which were subsequently inspected for MEC/MPPEH by teams of unexploded ordnance (UXO) technicians using handheld electromagnetic metal detectors. For discrete
DGM anomalies, APTIM reacquired the anomalies with survey equipment and used handheld metal
detectors and removed the anomalies via mechanically-assisted hand digging. With the assistance of handheld metal detectors and mini-excavators, the step-out areas were cleared via hand digging. APTIM also performed monthly seawall sweeps for MEC/MPPEH along the Andrew Lake Seawall during the months that the APTIM crews were working on Adak. |

CERCLA Remedial Action Completion Report |
Under the Comprehensive Environmental Response, Compensation, and Liability Act and the Federal Facilities Agreement, the U.S. Department of the Navy (Navy) is required to complete necessary munitions and explosives of concern (MEC) removal actions for site areas within Operable Unit (OU) B-2 on Parcel 4 of the former Adak Naval Complex, located at Adak Island, Alaska. See Figure ES-1 for an overall site layout and completion status. OU B-2 contains five remedial action areas (RAA). The Navy is performing the required removal activities under a non-time critical removal action (NTCRA) to satisfy the remedial action objectives identified as the preferred remedy from the Proposed Plan for Operable Unit B-2 Cleanup of Munitions and Explosives of Concern, Former Naval Air Facility Adak, Adak Island, Alaska (Navy, 2012). Upon completion, it is the Navy’s intention to return the property to the U.S. Department of the Interior. Currently, OU B-2 is in the removal action investigation phase of the Comprehensive Environmental Response, Compensation, and Liability Act process. The Navy began conducting NTCRA activities in 2013. In years 2013 and 2014, the Navy completed, with regulatory approval, the removal actions in RAA-02, RAA-03 (East), and RAA-04. The three remaining in-process OU B-2 sites at that time were RAA-01, RAA-03 (West), and RAA-05. The Navy continued NTCRA activities in the final three RAAs during the 2015 through 2018 field seasons. By the completion of the 2018 season, removal actions at RAA-01 and the remaining RAA-03 (West) grids were completed, leaving RAA-05 as the only incomplete site.
This report documents Aptim Federal Services, LLC (APTIM)’s results for the 2019 season at RAA-05 Andrew Lake Disposal Area -02 (ALDA-02) and Andrew Lake Seawall (ALSW). The scope of this work was to remove MEC and/or material potentially presenting an explosive hazard (MPPEH) from areas within RAA-05 ALDA-02 and ALSW. MEC/MPPEH were removed by conducting excavations of disposal areas, and surface clearance in the areas adjacent to the disposal areas. For disposal areas, APTIM used
armored, long-reach excavators to remove material and spread it into lifts, which were subsequently inspected for MEC/MPPEH by teams of unexploded ordnance technicians visually using screening/sorting tables or with handheld electromagnetic metal detectors on wooden search pads. For surface clearance areas, APTIM cleared these areas via hand digging of metallic items at the surface.
During the months that the crews were working on Adak, APTIM also performed monthly seawall
sweeps for MEC/MPPEH on the cobble beaches on ALSW and adjacent to ALDA-02. |

Document, Report, or Work plan Review - other |
Quality Assurance Surveillance Report. The QA field effort for the 2019 field season involved three QA personnel on island. A total of 4,956 man hours were expended during the field season. QA personnel conducted 135 field surveillances and 1,632 trench/lift inspections. Thirty-eight QA BSIs were emplaced in the trenching operations and 38 QA BSIs were emplaced in the surface clearance areas. All QA BSIs were successfully recovered by the production contractor. The QA team verified 154 surface clearance grids completed by the production contractor as complete. One NCR was issued by QA during the 2019 field season; the corrective action was successfully completed by the production contractor to remedy the issue. No major safety incidents occurred during the field season. Overall, the production contractor successfully implemented the processes delineated in the QAPP and other pertinent project documents. The work completed by the production contractor met all of the criteria for acceptance during the final QA checks. |

DEC Non-Concur on Federal No Further Action Decision |
On 2/28/2025, DEC issued a non-concurrence for the Revised Draft OU B-2 ROD, which addresses 24 sites in Parcel 4. The responses to comment provided by the Navy do not adequately address DEC's concerns. Lacking a rewrite, DEC cannot concur with the Revised Draft (OU) B-2 ROD and it would not be productive to engage in additional rounds of response to comment on this current version of the ROD. Additional information is detailed in the 2/28/2025 letter and attached comment table. |
