J;(;,/zment Summary ofNMED Comment Fort Bliss Response to NMED Comment NMED No. Concurrence

(YIN) 1 Provide format for presentation of sampling Fort Bliss (FfBL) will develop a format for presenting the results of

results per HSWA Module V.3.g.2 the laboratory analysis of samples that will facilitate comparing these results with various regulatory standards, action levels, background levels, etc., including the USEPA Region 03 RBCs. This format and a list of references for standards will be included in the revised RFI Workplan (WP).

2 Use current NM groundwater regulations in The revised WP will reference NM Water Quality Control WP Section 3 Commission Regulations as amended through 10/27/95.

3 Provide baseline risk analysis for sites FfBL will incorporate into the WP a program for production of a where EPA Region 03 RBC numbers are baseline risk assessment at all sites where the EPA Region 03 RBC exceeded action levels are exceeded. Language will be added specifying that

the NMED be contacted immediately if there is an "imminent and substantial danger to human health or the environment" posed by contamination at any of the nine sites.

4 Evaluate ecological receptors for risk FfBL concurs with this comment. The text in the section of each estimations site workplan that discusses potential receptors will be expanded to

elaborate on the items detailed in the NMED comment and in Section V.3.e.5 of the HSW A permit. Migratory bird populations will be evaluated with respect to reported pesticide contamination at SWMU25B

5 Risk assessments must use EPA default FfBL will take a phased approach to risk assessment at sites where parameters for residential exposure such a measure is required. The first phase will consist of a

qualitative assessment. This would include an evaluation of the type, amount, physical and chemical state, toxicology and bio-availability of all contaminants present at the site. The potential migration pathways will be identified and assessed. Potential human exposures will be addressed. Based on the results of the qualitative assessment, the need for quantitative data may be determined. In conjunction with the response to comment #6 below, the decision criteria for evaluation of quantitative data may be selected following

(YIN) completion of the quantitative study.

6 Concerns potential future land uses and FTBL agrees that a deed restriction, or some other land use cleanup standards restriction, may be necessary at some sites. We believe that it would

be more appropriate for these issues to be addressed in the Corrective Measures Study which will follow the RFI.

7 Identify SWMU coordinates and place The WP will be revised to include a description of the survey plan permanent markers at SWMU sites which will tie the individual site surveys to the current North

American Datum (NAD). Brass tabs affixed to concrete monuments will be constructed at each SWMU.

8 Requires remote QNQC background The WP will be revised accordingly. Background data for all sampling locations for each of the three McGregor Range sites will be obtained from the existing posts. background data related to the McGregor Open Detonation

Treatment unit. One remote boring at each of the Dona Ana and Orogrande Range Camps will be added to provide background data for soil borings at SWMU sites in the vicinity of those two locations.

9 Include test for explosive materials and FTBL does not propose to sample media for explosives at the residues in all media samples at all landfill landfill sites. There is no indication in the March, 1989, RCRA and OD sites Facility Assessment that there are any explosive materials deposited

in any of the landfills. FTBL will test all samples taken at SWMU #20 for explosive materials since this was an open detonation area.

10 Include evaluation of landfill caps per NM FTBL will revise the WP to include evaluating the caps at all four Solid Waste Management Regulations landfill sites in terms of the requirements of (EIB/SWMR-4). The (EIB/SWMR-4). Evaluate erosion potential relevant portions of the SWMR will be included in the Appendices. at landfills. Erosion potential will be evaluated.

11 Provide separate letter describing current FTBL will provide a letter describing current solid waste disposal solid waste disposal practices at NM posts. practices at NM posts.

12 Any changes to approved WP activities FTBL will revise the WP to specifically address coordinating with during the course of the investigation should the NMED any proposed changes to the approved Workplan be coordinated with the NMED activities that may required during the course of the investigation.

13 Concerns sampling procedures for VOCs The table being developed in response to comment #17 will clarify which particular sampling methods will be employed for particular types of media and the related laboratory analyses.

14 Include "extensive" soil vapor surveys at all A program for soil gas sampling at each of the four landfills has landfill sites. been developed by FfBL. The WP is being revised to include from

ten to fifteen soil gas sampling points at each landfill site. FfBL proposes to use an active gas extraction method based on ASTM

landfill sites. FfBL to include siting the perimeter vertical borings as close as possible to the waste trenches without penetrating the waste mass. In addition, vertical borings will be sited between trenches, where applicable, within the interior of the trench zone. Angle borings to beneath the waste mass will be added to the boring program. The results of the exploratory geophysical program and the soil gas sampling program will be utilized to optimize siting of the soil borings.

16 Elaborate on program to define landfill FfBL will expand and clarify the WP discussion of the geophysical boundaries. mapping program.

17 Identify EPA SW-846 methods to be used A table is being developed for inclusion into the Data Collection per HSWA Section N.1.b.3. section of the WP that will identify SW-846 methods to be used for

each laboratory analysis. 18 Provide "conclusive evidence" of The WP will be revised to specifically discuss the use of the most

The twenty-five pages in Landscape, starting with page 7, the brief Resumes of Key Persons, contributes nothing to this project.

The Data Item Description tells what should be in a Work Plan, BUT IS NOT A Work Plan. The infor111ation in this document should be ~leted to provide a complete Work Plan.

Appendix A, Safety Instructions, is outdated.

Annex A is included twice.

Annex B, Hazard Analysis; Activity1 Perfom mco Recovery Operations. This contr~ct does not call for uxo recove:r;y operations. 'lb.e Hazard Analysis should addre~s uxo avoidance and intrus.ive activities at the wste s.ites. The last Activity is Perform Final uxo Disposal Actions; and. if th,e contractor is going to perform dis­posal actions, the procedures must be written in this Appendix, to include controls, notification, explosives sto~age/transportation, etc~
