Rocketdyne Project Manager: Art LenoxCon tractor Project Manager : Dixie HambrickReport Period: August 16 - November 15, 200 1

1. PROGRESS MADE THIS REPORT PERIOD

Limited soil sampling was performed this period based results of previous samplingefforts and DTSC's comprehensive RCRA Facility Investigation (RFI) review .Montgomery Watson Harza (MWH) collected a total of 5 soil matrix samples and 45 soilvapor samples at 3 Rocketdyne sites during this reporting period (Table 1) . Soil matrixsample analysis was conducted by Ceimic Laboratories, a California-certified laboratorylocated in Rhode Island . Soil vapor sample analysis was conducted at an onsite mobilelaboratory by Centrum Analytical Laboratories (also California-certified for soil matrixanalysis) . To date, approximately 1052 soil vapor (1141 analyses) and 2745 soilmatrix/surface water samples (5763 analyses) have been collected from Rocketdynelocations during the RFI program (Table 2) .

Field work for the near-surface groundwater investigation resumed this period . Threeadditional shallow piezometers were drilled and installed at Rocketdyne sites duringNovember 2001 . These piezometers will be developed and sampled during Spring 2002 .Water level monitoring continued (one site-wide manual measurement and continualtransducer measurements at representative locations) . A draft technical memorandumdescribing Fall 2000/Spring 2001 investigation findings was prepared and discussed withDTSC. Preparation began on a spring/seep sampling and analysis work plan .

DTSC, Rocketdyne, and MWH met several times this period to discuss SSFL buildingreview approach, groundwater investigation findings, and the SSFL RCRA CorrectiveAction schedule. These meetings are part of an ongoing, comprehensive review processwith DTSC to describe site activities, soil and groundwater sampling results and fieldactivities, and review findings at each Solid Waste Management Unit (SWMU) and Areaof Concern (AOC) at the SSFL. This review includes SWMUs and AOCs identified inthe 1996 RFI Work Plan and its amendments, the 1994 RCRA Facility AssessmentReport, and the 1997 USEPA aerial photographic review . Rocketdyne sites reviewed todate include:

• SWMU 4.1 - Old B-1 Area• SWMUs 4.3, 4 .4, AOC - Instrument and Equipment Laboratories (IEL)• SWMU 4 .7 - Component Test Laboratory III (CTL-III )• SWMU 4.9 - Advance Propulsion Test Facility (APTF)• SWMU 4.12 - Laser Engineering Test Facility (LETF) / Component Test Laboratory

Draft soil sampling result maps and cross-sections have been prepared for Rocketdynesites to evaluate potential data gaps for the risk assessment process. To date, draft mapshave been prepared for 19 Rocketdyne sites .

Validation of recent soil samples and conducting a program quality assurance (QA)review of soil sampling data are ongoing.

A draft Surficial Media OU SRAM Addendum was submitted to DTSC this period . Thisaddendum includes information regarding risk assessment methodology for ecologicalscreening levels (ESLs), biological accumulation factors (BAFs), polychlorinatedbiphenyl (PCB) congener and arochlor data, and inorganic background concentrations forgroundwater .

2. SUMMARY OF FINDINGS

Preliminary results for soil and sediment samples collected this period indicate elevatedconcentrations at the following sites :

• B-1 Area - volatile organic compounds (VOCs)• SRE - mercury

Shallow groundwater level data this period were similar to last period and continue toshow a slow water level decline following the last significant rainfall in March . Finalresults for groundwater samples collected during AprilfMay 2001 indicate elevatedconcentrations at or near the following sites :

• 1EL -VOCs• Canyon - VOCs
