Rocketdyne Project Manager: Art LenoxOgden Project Manager: Dixie HambrickReport Period: November 16, 1996 through February 15, 199 7

1 . PROGRESS MADE THIS REPORT PERIOD

Implementation of the RFI field sampling program began on November 25, 1996 and is ongoing .Prior to sampling, utility clearance surveys have been conducted using electromagnetic (EM) andground penetrating radar (GPR) techniques at all subsurface sampling locations . Approximately300 sampling points have been cleared using EM and 235 points using GPR during this reportingperiod . Soil vapor sampling has been conducted 35 days during the period between November 25`x'and February 15`s . Above-average rainfall amounts have caused several field delays during thisperiod and field work was halted for two weeks in early February to allow saturated soils .to dry .As of January 31s`, a total of 301 soil vapor samples have been collected at 130 locations at 18 RFIsites . A summary of the soil vapor sampling progress at the Rocketdyne RFI sites is presented inTable 1 (attached) .

Subcontractors implementing the RFI field program include Transglobal EnvironmentalGeochemistry (TEG) for soil vapor/soil matrix sampling and onsite mobile laboratory analysis,Utility Locating Service, Inc . (ULS) for utility clearance, and Lockheed Analytical Services (LAS)Laboratory for offsite soil matrix and water analyses . Ogden was informed that LAS Laboratoryhas been sold to Southern Petroleum Laboratories (SPL) in January 1997 ; no impacts to the RFIfield program are anticipated by this sale because all LAS laboratory protocols and personnel willbe retained .

Rocketdyne, Ogden, and DTSC met several times during this period to review soil vapor samplingresults, new site use information, and proposed revisions to the soil matrix sampling program .Two meetings were held in December 1996 to discuss and observe sampling at the RFI sites . Newsite information findings were discussed with DTSC at a meeting held on January 21g, and sitevisits were conducted on January 240 . Proposed revisions to the soil matrix sampling programbased on results of the soil vapor sampling and new site use information were discussed withDTSC on February 7th and 140' .

Rocketdyne has offered members of the public access to observe the field sampling program at theSSFL. Prior to access, however, Rocketdyne has requested that all participants attend a SSFLsafety training session . Approximately 12 members of the public attended the first RFI publictraining session conducted by Rocketdyne on January 1601 . One group of public members observedsoil vapor sampling on February 1001 .

Development of a site-wide SSFL human health and ecological risk assessment approach continuedthis pe riod . Work on these tasks focused on compiling all background sample information ,

isevaluating background analysis methods, and determining the approp riateness of using theCaITOX risk assessment code for site-wide use. Rocketdyne , and Ogden met on Feb ruary 12th todiscuss the overall approach and preparation of the SSFL risk assessment work plan .

O ther tasks conducted for the RFI du ring this pe riod included continued entry of the previouslycollected soils data into the soil database , quality assurance/quality control (QA/QC) checks of thisdata, establishing a graphical ecological datab as e , and completing the biological mapping at theSSFL . All new soil vapor sampling points have been su rveyed in the field, digitized, and are beingentered into the GIS database . Soil vapor sampling results and new site use data are currentlybeing compiled and plotted, and proposed soil mat rix sampling locations reviewed for approp riatesampling depth and bo ring location .

2. SUMMARY OF FINDING S

Review of engineering diagrams and site inspections performed during utility clearance activitieshave provided addition information regarding historical activities at selected Rocketdyne RFI sites .This information has been researched through interviews with facility operations personnel, andhas prompted Rocketdyne to recommend additional sampling to be. included at 10 of theRocketdyne RFI field sites . Limited sampling is also recommended at the Component TestLaboratory I and V (CTL-I and CTL-V) facilities because new site use information has indicatedthat at least limited quantities of solvents and fuels were used during historical operations at thesesites . These sites were not- originally included by the EPA as Solid Waste Management Units(SWMUs) -or Areas of Concern (AOCs) during the RCRA Facility Assessment (RFA) .

New site information findings were discussed with DTSC at the January meetings . Based ondiscussion with DTSC, sampling at the CTL-I site will be conducted as part of the investigation atthe Laser Engineering Test Facility (LETF, SWMU 4 .12), located adjacent to the CTL-1 facility .Sampling at the CTL-V facility will be performed as a new Area I AOC . A summary of the newsampling proposed at the Rocketdyne field sites during the RFI field program is presented in Table2 (attached) .

Soil vapor sampling was conducted at 10 Rocketdyne RFI sites during this reporting period . Todate, soil vapor sampling has been completed at 4 Rocketdyne RFI sites (Happy Valley, Building359 Sump, APTF, and Bowl) . The highest concentrations of volatile organic compounds (VOCs)have been detected in three general areas at the Instrument and Equipment Lab site (SWMUs 4 .3,4.4, and AOC), and at the CTL-III pond (SWMU 4.7) . Slightly elevated VOC concentrations havealso be detected at the Happy Valley site (Area I AOC) and near the solvent storage area at CTL-III . Table 3 (attached) summarizes the maximum observed soil vapor concentrations for VOCsdetected in the samples collected during November, December, and January for each RocketdvneRFI site sampled . (Soil vapor data collected during February are not reported in Table 3 becausedata reports have not been submitted by the laboratory or validated for use . )

Background analysis methodology, future site use options, and the use of CaITOX as the riskassessment modeling code were discussed at the February 12`h meeting . A meeting schedule withDTSC concerning these topics is being developed .

5. PROJECT ACTIVITY NEXT PERIOD

Implementation of the RFI field program will continue . Soil vapor sampling is anticipated to becompleted by February 21 ' . Soil matrix sampling will begin on February 17`' . Strataprobesampling will be conducted first at all active RFI sites at the SSFL, beginning with the sites inArea I . Hand auger sampling will first target all sludge and test area pond sampling locationsbecause analytical results from these locations will determine further downstream or adjacent soilmatrix sampling analytical requirements .

RFI sampling laboratory reports will be reviewed and validated, and entered into the soilsdatabase . Sampling results will continue to be evaluated in the field for additional samplingrequirements during the field program . Plots of the field data will be prepared throughout the fieldprogram to aid in this evaluation .

Revised soil matrix sampling locations based on the new site use information and soil vaporsampling results will be finalized through continued discussion and site visits with DTSC nextperiod . Proposed revisions to the field sampling program will be summarized and documented in aletter for DTSC in March 1997. -

Development of the site-wide risk assessment activities will continue, and preparation of the riskassessment work plan will begin. A meeting schedule for continued discussion with DTSCconcerning risk assessment activities will be prepared and finalized .

2. SUMMARY OF FINDING S

Review of engineering diagrams and site inspections performed during utility clearance activitieshave provided addition information regarding historical activities at selected NASA RFI sites .This information has been researched through interviews with facility operations personnel, andhas prompted Rocketdyne to recommend additional sampling to be included at 5 of the NASA RFIfield sites . Limited sampling is also recommended at the Coca/Delta Fuel Farm area to determinethe extent of fuel hydrocarbons in soils near the former above ground storage tanks . This site wasnot originally included by the EPA as a Solid Waste Management Unit (SWMU) or Area ofConcern (AOC) during the RCRA Facility Assessment (RFA) .

• New site information was discussed with DTSC at the January meetings . Based on discussion withDTSC, sampling at the Coca/Delta Fuel Farm will be conducted as a new Area II AOC. Asummary of the new sampling proposed at the NASA field sites-during the RFI field program ispresented in Table 2 (attached) .

Soil vapor sampling was conducted at 6 NASA RFI sites during this reporting period. To date,soil vapor sampling is not complete at any of the NASA RFI sites because of saturated soilconditions . The highest concentrations of volatile organic compounds (VOCs) have been detectednear test stand no . 1 at the Alfa site (SWMUs 5 .9, 5 .10, and 5 .11) and near the solvent storagearea at the Bravo site (SWMUs 5 .13, 5 .14, and 5 .15) . Low concentrations of VOCs were alsodetected at one location at the SPA site (Area II AOC) . Table 3 (attached) summarizes themaximum observed soil vapor concentrations for VOCs detected in the samples collected duringNovember, December ; and January for each NASA RFI site sampled . (Soil vapor data collectedduring February are not reported in Table 3 because data reports have not been submitted by thelaboratory or validated for use . )

Background analysis methodology, future site use options , and the use of CaITOX as the riskassessment modeling code were discussed at the February 12'h meeting. A meeting schedule withDTSC concerning these topics is being developed .
