Subject: TIM for CSSA Environmental Projects, Parsons ES, contractor

The meeting was held at the CSSA Building One conference room, beginning at 0900 hours on October 2, 1997. This meeting was attended by representatives of CSSA, AFCEE, Parsons ES, Waste Policy Institute, and Booz-Allen & Hamilton. The following were in attendance (see attached sign-in sheet for TIM attendees):

Meeting Purpose

The purpose of the TIM was to discuss environmental projects being performed at CSSA. A short executive session was held to update the CSSA Commander, Col. Roberson.

Meeting Agenda

The agenda was as follows:

1. Introductions

2. Project overviews and budgets (executive session with Col Roberson attending)

3. Discussions of laboratory analytical qualifiers

4. Format for environmental encyclopedia

5. Project status, AMC task order RL 17 (SWMU Closures)

6. Project status, AMC task order RL 33 (B-20 and GIS)

7. Project status, AFCEE delivery order 0023 (Groundwater Monitoring and Wells)

Project overviews and budgets (Executive Session)

Discussions of laboratory analytical qualifiers

Karuna Mirchandani needed clarification on flagging data with AFCEE qualifiers. Jo Mullen started with the inorganics (metals) - Parsons ES is to use approved background values as comparison. All non detected values to be flagged with a ‘U’ flag and reported at the SQL. Jo Mullen defined the SQL as half the AFCEE reporting limit/PQL. Any value between the background value and PQL is to be flagged with an ‘F’ flag.

Jo Mullen was concerned about the data for the organics (VOCs and SVOCs), since background had not been calculated for these parameters. As the old data did not have MDLs reported on the forms reported by the laboratory, the concern was that the PQLs used by the laboratories in the past (pre-AFCEE QAPP) would be higher than the current AFCEE PQLs. This would result in potentially incorrect non-detected values being reported when compared to current AFCEE PQLs.

Parsons ES suggested that they would query the current SVE and SWMU data for all values detected above the MDL. They would also compare the existing old data to the current AFCEE PQLs. The conflicting data would then be discussed with AFCEE via e-mail or teleconference.

Susan Roberts mentioned that this would affect the SVE report due October 21st and that an extension would be necessary. Jo Mullen said she would talk to Matt Bowen on October 3rd about the extension date.

Format for environmental encyclopedia

Teresa Anderson showed an example of the environmental encyclopedia format in binders and a draft table of contents. During the discussion over the format, it was decided that a Record of Revisions page would be specific to each volume, each volume will have a table of contents that applies to that volume, and a master table of contents will be placed in Volume 1. Previously published documents will not be split up except for the RL17 work plan.

A list of relevant previous investigations conducted (such as soils gas surveys, geophysical surveys, etc. which are in large reports) will be included for each site. This list will provide a way for the reader to know that the investigation was done at the site; this way the previously submitted reports will not have to be resubmitted.

Volume 6 will be added. It will include all permits (NPDES, monthly effluents, air permit, standard exemption, etc.). The last volume will be for areas of potential concern. The regulators are not required to have these two volumes.

The number of copies required was discussed. CSSA would like three, AFCEE would like one, Parsons ES needs one. Susan Roberts mentioned that TNRCC has requested that three copies of all reports be sent to them. She also mentioned that the TNRCC copies of the encyclopedia will probably not get updated unless Parsons ES does it for them.

Parsons ES will prepare a revised table of contents for the encyclopedia based on the discussion at the meeting. Susan Roberts indicated that she would like approval of the table of contents before Parsons ES continues with preparation of the encyclopedia.

Lunch Break 12:45 to 1:45 p.m.

Project status, AMC task order RL 17 (SWMU Closures)

A discussion was led by Susan Roberts regarding the SWMU closure reports for this project. Prior to submitting a complete document, Jo Mullen requested that the ITIR tables would be sent by email for her review. Ms. Mullen also added that the closure reports should include a CSSA overview map, site map, and color photo. Ms. Roberts stated that a volume number would be part of the footer in each report and that page numbers would be sequential within a report, but would not be tied to other reports.

Ken Rice gave an update regarding the electrokinetic treatability study at the oxidation pond (O-1). The treatability study was initiated at the site after the bench-scale study indicated a 94% removal efficiency for chromium. At the actual site, Lynntech has had a problem with the buffering capacity of the soil. Electrokinetics needs acidic conditions to work most effectively. Lynntech has worked with several different acidic compounds to reduce the alkalinity of the soil. They have found that an HCl-citric mix worked the best, got the soils down to pH of less than 3. Trivalent chromium did not convert to hexavalent chromium under citric acid conditions. The field test began in late August 1997. The first step was acidification of the soils, as described above. Tom Rogers of Lynntech was concerned about the distribution of the acid - he wanted to be sure that deeper soils, not just the surface, were acidified, so he used probes to “inject” the acid. Initial profiling samples have been collected at the site; additional samples will be collected next week. No QA/QC is being run on interim samples collected at O-1.

Ken Rice presented a summary of the waste issues and ongoing discussions with the regulators. Mr. Rice gave a synopsis of what has transpired regarding this issue, starting with Malcolm Ferris’ visit to CSSA. TNRCC’s and CSSA’s concerns were discussed (as shown in meeting materials). CSSA and AFCEE directed Parsons ES to continue dialog with TNRCC lawyers. Brian Murphy also indicated that he discussed this issue with Greg Lyssy at EPA. Mr. Lyssy said that the work that CSSA is doing at the sites is corrective action.

Project status, AMC task order RL 33 (B-20 and GIS)

Results of the field investigations to date were summarized. UXO clearance was just completed on Tuesday (September 30) and UXB International demobilized at that time. Sites swept included B-8, B-20, B-24, B-28, and DD. UXO screening was also completed at Bldg. 43, B-10, and B-2. Available soil results for these sites were also discussed. Soils at B-20, B-24, B-28, and DD exceed RRS2 criteria, most commonly for lead, but some other metals as well.

Phytoremediation bench-scale treatability study is ready to commence. A copy of Phytotech’s work plan was distributed. Parsons ES has identified a couple of potential bidders for the soil washing bench-scale treatability study, but asked AFCEE if they know of any potential subcontractors. Wes Dalton indicated that he would look into it.

Julie Burdey mentioned that the waste issue with the TNRCC will delay project reporting. To be cost effective, waste disposal efforts will be coordinated with drilling efforts to minimize the number of people in the field. Reports cannot be submitted until drilling and waste disposal has been completed. According to the current project schedule, closure/investigation reports for the sites will be due in the November-December timeframe. This schedule cannot be met if the TNRCC waste issue is not resolved quickly. Jo Mullen recommended that Parsons ES notify AMC that all reports will be extended due to regulatory issues: 1) description of problem, and 2) leave off sites that can be closed.

Jo Mullen indicated that she is anticipating receiving ArcView soon and would like a copy of the CSSA GIS. Teresa Anderson added that Jo could call up the Parsons’ dial-up server and we anticipate that the database/GIS could be loaded without an extra trip.

Project status, AFCEE delivery order 0023 (Groundwater Monitoring and Wells)

Groundwater monitoring will be back on schedule after lengthy delay. QED pumps have been ordered. Monitoring schedule will be adjusted due to delay. Well installation evaluation will be initiated after the two rounds of quarterly data have been collected and evaluated. The evaluation will address the cost of three separate wells vs. cluster wells, rationale. Brian Murphy indicated that regulatory approval of selected well locations will be sought.
