Regulatory Guidance

CERCLA preferred MMRP regulatory guidance

However, state may exercise authority under RCRA

Camp Bullis has RCRA permit

TCEQ requested Camp Bullis be evaluated under RCRA

Army agreed, TCEQ is the lead regulatory agency

MMRP RFA Goals

Primary GoalTo support one of the following recommendations

No Further ActionImmediate Response;Further Characterization

Secondary GoalTo apply the information to:

Refine the MMRP CTC estimates by ArmyUpload RFA analytical data into ERISPopulate the MRS-PP & calculate draftscores for each MRS

MMRP RFA Process

Establish and involve stakeholders throughoutDevelop/accomplish DQOsPerform historic records reviewDevelop CSM and determine data gapsDesign Work Plan and perform field workRFA

RFA Results - MCAs TCEQ is lead agency, stakeholders agreed

Use TRRP PCLs for residential levels in soil for comparison

Explosives (EPA Method 8330) assessed at two MRSs.

No explosive compounds detectedTAL Metals (EPA Method 6010B) assessed at all four MRSs.

Metals detected at 2 MRSs

RFA Results - MC

thallium 6.3 mg/kgthallium 8.07-12.0 mg/kg75 mm Munitions SiteTRRP Tier 1 PCLsMC DetectedMRS

All 8 samples collected showed slightly elevated levels of thallium.Thallium is associated with the potassium minerals in clay soils.Camp Bullis IRP is investigating thallium throughout the installation.Stakeholders felt thallium issue notrelated to munitions.

RFA Results - MEC

Stokes Mortar RangeMEC confirmed during HRR

75 mm Munitions SiteDGM – performed to refine MRS boundary and support historic evidence of site as DMM site.Covered 76 % of the MRS.

RFA Results - MC

Copper Conclusion: “ Due to the very low detections of copper from the samples analyzed on 3 June 2005 and 14 July 2005, there does notappear to be a concern with high levels of copper at the site.”*

RFA Field Work

•Memorandum, to TCEQ, Region 13, RE: Copper sampling Results from MMRP Site, 100 Target Range, US Army Camp Bullis, Texas, from Director, Environmental and Natural Resources Office.

RFA Conclusion – Stokes Mortar Munitions Site

Further Characterization:

MEC: Documentation indicates MEC has been found throughout the MRS.

MC: Metals and explosives were not detected

RFA Conclusion – 75 mm Munitions Site

Further Characterization

MEC: MEC has historically been discovered at this MRS and DGM detected 160 anomalies supporting reasonable cause for further investigation.MC: Thallium detected in all 8 surface soil samples.

RFA Conclusion - 100 Target Range

No Further Action

MEC: MEC is not associated with the MRS.MC: Copper and thallium exceeded PCLs.

Copper was determined to be an outlier by follow up samplingThallium determined not a contaminant of concern by stakeholders.

RFA Conclusion – Machine Gun Range

No Further Action

MEC: MEC is not associated with the MRS.

MC: MC was not detected in levels which exceed TRRP Tier 1 PCLs at the MRS.
