[SWMU B-8]

SWMU B-8 Work Plan
RL17 Project, February 1996

Soils: Krum Complex

Known: Fired small arms ammunition brass area consisting of piles of fire bricks and ammunitions, shells, and remains.

Previous investigations: An isolated anomaly was detected to the east of the burn area and may be associated with buried metal debris (Parsons ES, 1995c). Figure B8-1 illustrates the extent of B-8 and the approximate size and location of the anomaly therein. Scattered bricks and an abandoned metal pipe are also shown in the figure but do not have any bearing on the closure procedures. A soil gas survey has not been conducted at this site.

Data Needs: Analytical data (VOCs, explosives, and metals) for groundwater, surface, and subsurface soils.

Closure Activities: The field team should be observant for UXO. The following field activities will be performed to gather data for TNRCC closure submittal of SWMU B-8.

SWMU B-8 Field Effort 1

  1. Review historical records as described in Section 2.4.1 of the Work Plan Overview.

  2. Locate and receive approval for three soil borings at the approximate locations shown on Figure 3.4 as described in Section 2.4.1 of the Work Plan Overview.

SWMU B-8 Field Effort 2

1. Three soil borings will be drilled to characterize the subsurface soils.

a) Drill the three soil borings in the approved locations as described in Section 2.4.1 of the Work Plan Overview.

b) Obtain three samples per boring near surface (0-2 foot depth), middle, and total depths as described in Section 2.4.1 of the Work Plan Overview.

2.  Analyze each sample for VOCs, metals, and explosives (as outlined in the FSP).

3.  Water is not expected to be encountered at the site. However, if water is discovered in any of the soil borings, all three borings will be sampled and potentially completed as groundwater monitor wells as detailed in Section 2.4.1 of the Work Plan Overview. Sample groundwater, where present, and analyze each sample for the metals, explosives, and VOCs (as outlined in the FSP).

4.  Handle the IDW in accordance with the FSP.
