ES.1EXECUTIVE SUMMARY

This Resource Conservation and Recovery Act (RCRA) Facility Investigation(RFI) Work Plan (WP)summarizes previous investigations and proposed additional investigation activities at Solid Waste Management Unit (SWMU) 14, SWMU 15, SWMU 33, SWMU 74, Area of Concern (AOC) 89, AOC 90, AOC 91, and AOC 92within Parcel 3 at Fort Wingate Depot Activity (FWDA), New Mexico.

The Historical Information Summary Document for Parcel 3 was previously finalized in 2008 to compile and summarize historical documents available for the SWMUs and AOCs (TPMC, 2008). The Historical Information Summary Document for Parcel 3 is included as Appendix A for reference. The Historical Information Summary Document provides further detail regarding the operational history, site and facility drawings, geophysical surveys, and environmental information contained in previously completed reports.

This RFIWP has been prepared for submission to the New Mexico Environment Department (NMED) Hazardous Waste Bureau, as required by Section VII.H.1.a of the Resource Conservation and Recovery Act (RCRA) Permit NM 6213820974-1 for the FWDA (the Permit), effective onDecember 31, 2005 and modified in 2014. The Department of Defense (DoD) Base Realignment and Closure (BRAC)-Divisionand U.S. Army Corps of Engineers (USACE) mission is to complete the environmental remediation and restoration activities at FWDA to support final property transfer of most of the property for reuse by the Navajo Nation (NN) and Pueblo of Zuni (POZ) in accordance with the above-referenced permit.

Existing data have been evaluated to determine field activities required to characterize the nature and extent of potential environmental impacts at the above listed SWMUs and AOCs. Sections5.0 through 11.0 of this RFI WP evaluate the existing data for the SWMUs and AOCs and propose additional data-gathering activities. Brief summaries of these areas are provided below and inTable ES1.

All soil investigation activities will be conducted in accordance with proposed actions and procedures specified in the NMED-approved WP. Other associated project-specific planning documents are discussed in this WP and provided as appendices.

SWMU 14

SWMU 14was used for demilitarization activities which were part of the FWDA mission of demilitarizing unserviceable, obsolete, and/or waste explosives, propellants, munitions and munitions components. SWMU 14,known as the Old Burning Ground and Demolition Landfill Area,consists of approximately 15 acres and is located in the north-central portion of Parcel 3. This area wasused between 1948 and 1955. Some of the demilitarization activities performed at this SWMU were accomplished using treatment by open burning (OB) or open detonation (OD). Related materials were also treated in these SWMUs, including objects potentially contaminated with explosives during storage and handling, such as shipping containers and dunnage. The proposed data gathering activities in SWMU 14are summarized in Table ES1.

SWMU 15

SWMU 15 was used for demilitarization activities which were part of the FWDA mission of demilitarizing unserviceable, obsolete, and/or waste explosives, propellants, munitions and munitions components. SWMU 15, known as theOld Demolition Area, is approximately seven acres and is located to the southwest of SWMU 14 in Parcel 3. This area was used between 1948 and 1955. Some of the demilitarization activities performed at this SWMU were accomplished using treatment by open burning (OB) or open detonation (OD). Related materials were also treated in these SWMUs, including objects potentially contaminated with explosives during storage and handling, such as shipping containers and dunnage. The proposed data gathering activities in SWMU 15 are summarized in Table ES1.

SWMU 33

SWMU 33 was used for demilitarization activities which were part of the FWDA mission of demilitarizing unserviceable, obsolete, and/or waste explosives, propellants, munitions and munitions components. SWMU 33, also called Waste Pile KP1, is approximately 0.04 acres and is located south of SWMU 15. This area was used between 1948 and 1955. Some of the demilitarization activities performed at this SWMU were accomplished using treatment by open burning (OB) or open detonation (OD). Related materials were also treated in these SWMUs, including objects potentially contaminated with explosives during storage and handling, such as shipping containers and dunnage. The proposed data gathering activities in SWMU 33 are summarized in Table ES1.

SWMU 74

SWMU 74 is approximately 1.4 acres and is locatedalong the eastern boarder of Parcel 3. This area was the Proposed Burning Ground identified in the Permit as Area 16 or Site 16; however, no records exist showing thatthe burning ground was ever established. The proposed data gathering activities in SWMU 74 are summarized in Table ES1.

AOC 89

AOC 89 is approximately sixacres and islocated in five separate areas along the north east boundary of Parcel 3.Three of these areas contain U-shaped revetments, one contains an L- shaped revetment, and one contains a rectangular cleared area with shallow trenches along two sides. The use of the L-shaped revetment was not documented in the historical records and its purpose is unknown. The remaining four areas were used as temporary storage areas for military munitions awaiting treatment by either OB or OD.The proposed data gathering activities in AOC 89 are summarized inTable ES1.

AOC 90

AOC 90 is approximately 1.7 acres and is locatedin two separate areas south of SWMU 15 along the western edge of Parcel 3. AOC 90 consists of two ponds which are dammed on the downstream end and are located topographically upgradient from all known areas of FWDA operations. One pond is outside of the of the FWDA western property boundary. The proposed data gathering activities inAOC 90 are summarized inTable ES1.

AOC 91

AOC 91 is approximately 28 acres and is locatedin the central portion of Parcel 3. This AOC consists of a disturbed area within the firebreak that is east and south of the known demolition area and a second disturbed area with many roads and paths. The proposed data gathering activities inAOC 91 are summarized inTable ES1.

AOC 92

AOC 92 is approximately 19.7 acres and is locatedinside the Inner Fence in the central portion of Parcel 3. This area has been identified as a “demil area.” AOC 92 is identified in the Permit as Feature 31 on the 1973 Aerial Photo API-5 and Feature 21 on the 1978 Aerial Photo API-7. Feature 31 is described as bare areas on a hillside with a loop road around the area, two trenches, three small pits, and three pit scars. Feature 21 is described as bare, rough ground on the side of a hill with loop road and two pits (USACE, 1995). The proposed data gathering activities inAOC 92 are summarized in Table ES1.
