INTRODUCTION

This Sampling and Analysis Plan has been prepared pursuant to the

request of the California Department of Toxic Substances Control (CA DTSC) and the United States Environmental Protection Agency (US EPA) in their

Closure Plan review comments for the Area I Thermal Treatment Facilit y at the Rockwell Santa Susana Field Laboratory (US EPA, CA DTSC, 1991) . This

Sampling and Analysis Plan (SAP) also addresses investigation of the Area

I Burn Pit Solid Waste Management Unit (SWMU No . 4 .1 .15) as identified in the US EPA Draft Visual Site Inspection Report for the Santa Susana Field

Laboratory (SAIC, 1991) . Rockwell is submitting this SAP concurrently with a closure plan for the Thermal Treatment Facility including proposed corrective actions for the EPA identified SWMU .

The SAP consists of two parts : the site specific Field Sampling Plan

(FSP) and the Quality Assurance Project Plan (QAPP) . The FSP provides guidance for all field work by defining site specific sampling and data gathering methods . The FSP is included in the main text of this SAP . The

QAPP describes organization and functional activities and quality control protocols, and is included as Appendix A of the SAP .

BNA0137257 3 HDMSE00620851 GROUNDWATER RESOURCES CONSULTANTS, INC.

PURPOSE AND SCOP E

The purpose of the SAP is to outline methods to determine the potential presence and extent of subsurface contamination, if any, in the vicinity of the Area I Thermal Treatment Facility . In addition, the SAP includes sampling of physical structures for the purposes of cleanup and closure activities .

The scope of work and sequence of events proposed for the program are described as follows :

• Sampling of existing physical structures to facilitate removal

and disposal in accordance with appropriate State and Federal

regulations .

• Geophysical survey to determine potential presence of buried

metal objects .

• Soil investigation including soil sample collection and

description of soils encountered during drilling operations .

• If shallow groundwater is present, installation of one shallow

zone monitor well and collection of two rounds of shallow

groundwater samples .

• Preparation of site base map .

limo II BNA01372574 HDMSE00620852 GROUNDWATER RESOURCES CONSULTANTS, INC .

Following completion of the field investigation, all results will be tabulated and summarized in a report presented to Rockwell .

FACILITY DESCRIPTION AND HISTORY

The Area I Thermal Treatment Facility consists of approximately one acre of land in the southwest corner of Area I of the Rockwell Santa Susana

Field Laboratory (SSFL) ( Figure 1 ) . The area of investigation is shown on

Figures 2 and 3 . This area currently includes two concrete pads, associated berms and a burn pit . The concrete pads and associated berms are no longer used for waste disposal purposes . One pad is located on the south side of the Facility and is 19 .5 feet by 20 feet . It is sloped downward toward the south and surrounded by a earthen berm on the southern and western sides .

The second pad is on the north side of the Facility . The pad is 6 .5 feet square and is surrounded on all sides by an eight foot high earthen berm .

A metal burn cage is housed on this pad . A demonstration firefighting area in the western portion of the Area I Thermal Treatment Facility is currently used for SSFL and Ventura County fire department training operations .

The Area I Thermal Treatment Facility was operated during the period

1958 through 1990 for the small scale destruction of explosive and flammable wastes by open burning . Previously, additional waste management and disposal structures existed in the Area I Facility . These structures are shown on the topographic map of the area prepared by Rocketdyne in June 1981

(Figure 2), and include the following features :

The numbers assigned to the above features have been added to the topographic map in order to identify features easily . The majority of the features were removed in 1989 , leaving only the two concrete pads, associated berms and firefighting pit .

During 1981, Rockwell contracted Harding & Lawson Associates to conduct a radar scan in order to identify buried objects and disturbed soils . Eight areas of buried debris, one area of sediment and thirty-four localized anomalies were located and subsequently excavated . The excavation areas have been designated as Excavation #1 through Excavation #6 by Groundwater

Resources Consultants, Inc . to facilitate identification . The volumes excavated are 59 cubic yards, 118 cubic yards, 59 cubic yards, 740 cubic yards, 29 cubic yards, and 592 cubic yards for Excavations #1 through #6, respectively . The total volume of excavated materials and soils wa s

DI DI U BNA01372576 HDMSE00620854 GROUNDWATER RESOURCES CONSULTANTS, INC .

approximately 1600 cubic yards . The identified areas of buried debris or sediment, anomalies and excavated areas are shown on Figure 2 .

PREVIOUS INVESTIGATION S

Previous investigations conducted by Rockwell have included groundwater and soil investigations throughout the SSFL Facility, and soil sampling activities in the vicinity of the Area I Thermal Treatment Facility . In - chloroethylene (ICE) was discovered by Rocketdyne in SSFL Facility water supply wells in 1984 . Subsequent groundwater investigations at the Facility have indicated that the groundwater underlying much of the Facility contains volatile organic compounds in excess of California Action Levels (CA OHS,

1990) . During the period of 1984 through the present over 150 monitor wells were constructed as part of the monitoring program to chemically character- ize and to assess the extent of degraded groundwater beneath the Facility

(Figure 4) . The monitoring program includes the collection and analysis of groundwater samples from wells and springs on a regular frequency and submittal of quarterly and annual monitoring reports to Rocketdyne . Currently, further site-wide assessment of hydrogeologic conditions is being conducted .

Soil sampling activities were conducted by Rocketdyne personnel at the

Area I Thermal Treatment Facility during 1981 and 1982 in preparation of closure and during 1990 as part of Resource Conservation and Recovery Act

(RCRA) permitting activities . Twenty-five soil samples were analyzed during the first event and six samples were analyzed during the second event . The analytical results are discussed in the following subsections .

I II BNA01372577 HDMSE00620855 GROUNDWATER RESOURCES CONSULTANTS, INC .

Soil Sampling Results from 1981 and 1982

In 1981 and 1982 Rocketdyne representatives collected soil samples from

the Area I Thermal Treatment Facility in preparation of closure . Eleven

samples (Rocketdyne sample numbers 1 through 7, 9 through 12) were collected

on October 15 and 16, 1981 . One sample was split with the California

Regional Water Quality Control Board ( CRWQCB ) . Nine additional samples

(Numbers 13 through 21) were collected on February 5, 1982 after a radar

scan had been performed by Harding Lawson Associates to identify locations

of buried materials . The samples were collected in the sides of a 40 foot

long and 3 foot deep trench excavated in the area of highest potential

contamination . The areas of buried debris or sediment and anomalies

identified by Harding Lawson Associates and the locations of the soil samples are shown in Figure 5 .

Selected samples were subsequently analyzed by the Santa Susana Field

Laboratory Analytical Chemistry Department for volatile organics, polynuclear aromatic hydrocarbons, phenols, total mercaptans, phthalates, metals, anions, formaldehyde and hydrazines . The analytical methods are described in Table 1 . In addition, selected samples were tested by Pacific

Spectrochemical Laboratory, Inc . of Los Angeles, California for semi- quantitative analysis of elements . The results of the 1981 and 1982 sampling events are presented in Table 1 . Results are presented in this work plan in micrograms per gram (µg/g) and milligrams per liter (mg/Q), which correspond to the laboratory reports . Both of these units are commonly referred to as parts per million .

Organic Result s

The results indicated that primarily low level concentrations o f volatile organic compounds were present in most samples . Many concentrations were reported as trace amounts not quantified above method detection limits of 1 µg/g and 5 µg/g . Detected compounds included 1,1-dichloroethane, chloroform, dichloromethane, methyl isobutyl ketone, toluene, 1,1,1- trichloroethane, ICE, and carbon disulfide . Concentrations were generally

10 µg/g or less . Three compounds were detected at higher concentrations in one sample : acetone at 160 pg/g, methyl ethyl ketone at 9Q µg/ g, and 2- propanol at 54 µg/ g (Table 1) .

Polynuclear aromatic hydrocarbons were detected at low concentrations

(3 µg/g or less) in eight samples (Table 1) . Detected compounds included pyrene, chrysene, fluorene, naphthalene, and phenanthrene . All other results were reported as less than the method detection limit (1 µg/g) .

Phenols wen ..Uetected in eighteen samples in concentrations ranging from l •cg - .t a ection limier to 23 µg/g, (Table 1) . T1a .,majority of repor°te~!'~et low concentrations (5 µg/g or less) with the excep~ti of which was detected at a concentration of 10

was not detected in any samples (detection limit of I mg/2) . Hydrazines

were detected at concentrations ranging from undetectable (0 .1 mg/2) to 3 .4

mg/2 . Mercaptans were detected at concentrations ranging from undetectable

(0 .1 .ig/g to 6 µg/g) (Table 1) .

Inorganic Result s

The highest concentrations of metals detected were 1,100 mgJe ( alumi-

num), 3 , 400 mg / 2 (iron ), 9,000 mg /@ ( phosphorus ) and 144 mg/i (silicon) .

Most of the twenty-two metals analyzed were reported at concentrations less

than 5 mg/2 (Table 1) .

Samples were analyzed for four anions : fluoride,. chloride, nitrate and

sulfate . Fluoride was detected at concentrations ranging from trace

[unquantifiable at 0 .1 milligrams per liter (mgJ2) j~ .liq+►id extract] to 2 .8 mg/e . Chloride concentrations ranged from undetectable at 2 mg/t to 13 mgJL Nitrate concentrations ranged from undetectable at 0 .5 mg/ 2 to 2 .0 mg/2 . Sulfate concentrations ranged from trace (detection limit of 5 mg/2) to 170m /r"

Semi-quantitative element results were available for eighteen samples .

Semi-quantitative element analyses indicated that silicon composed the highest percentage of the elements analyzed (23 to 32 percent) (Table 1) .

Rocketdyne subsequently submitted the results of the soil sampling at the Area I Thermal Treatment Facility and requested that the CRWQCB approv e

disposal of contaminated soil (approximately 1,400 cubic feet) at a Class

I landfill as a non-hazardous waste (Rocketdyne, 1982) . A response from the

CRWQCB was not present in the project files for further review . Per verbal communication with a former Rocketdyne employee , soil and debris were removed by International Technology Corporation under the observation of a

California Department of Health Services representative ( telephone conversation with Mr . Michael Francis , September 27, 1991 ) . A document containing a location map, laboratory reports and assessment of data was subsequently prepared by Rocketdyne ( Rocketdyne , 1982 ) . Approximately 1,600 cubic yards of soil and debris were removed . The excavation areas are shown on Figure 2 . A reproduction of the sampling plot plan contained in the

Rocketdyne document is provided as Figure 5 .

Additional Soil Sampling Results from August 198 2

Five additional soil samples were also analyzed during 1982 . Three of the samples were identified as part of a sampling effort conducted on August 18,

1982 (Rocketdyne sample numbers RTR-3, RTR-4 and RTR-5) . Samples RTR-3,

RTR-4 and RTR-5 were analyzed for six total metals (chromium, lead, zinc, cadmium, copper, and nickel), soluble and total fluorides and volatile organics . Information regarding specific analytical methods was not available . fle. results o these analyses are presented in Table 2 .

The additional sampling results from August 1982 indicated concentrations of chromium, lead, zinc, copper, nickel, soluble fluoride, total fluoride, and three volatile organic compounds (1,1,1-trichloroethane ,

BNA0137258 1 HDMSE00620859 GROUNDWATER RESOURCES CONSULTANTS, INC .

trichloroethylene and toluene) . Total concentrations of chromium ranged

1 .4 mg/kg . Trichloroethylene concentrations ranged from nondetectable to

4 mg/kg . Toluene concentrations ranged from nondetectable to 1 .6 mg/kg

(Table 2) .

Soil Sampling Results from 1990

In April 1990 Rocketdyne representatives collected six soil samples

from the Area I Thermal Treatment Facility as part of the Part B permit

application process . The samples were analyzed for the 17 metals listed in

the California Code of Regulations (CCR), Title 22 using the Waste

Extraction Test (W .E .T .) extraction procedure . Analyses were conducted by

the SSFL Analytical Chemistry Unit . The results are presented in Table 3 .

GEOLOGIC AND HYDROGEOLOGIC CONDITION S

GEOLOG Y

The SSFL Facility is located in the Simi Hills of eastern Ventura

County, California . The Simi Hills form the southern flank of a broad synclinal depression which constitutes Simi Valley . The Simi Hills are composed primarily of exposures of the Upper Cretaceous Chatsworth

Formation . This formation is a marine turbidite sequence composed of sandstone with interbedded siltstonejmudstone and minor conglomerate lenses .

The exposure of the Chatsworth Formation in the Simi Hills is characterized by massive, cliff-forming sandstone beds . In the southwestern portion of the Facility the Paleocene Martinez Formation is exposed .

The geologic units are overlain by a thin discontinuous layer of thin

Quaternary alluvium , most notably in the western portion of the Facility

(Burro Flats) and along ephemeral drainages . The alluvium consists of mix- tures of unconsolidated sand, silt and clay, which may be as thick as 20 feet in some areas .

At the SSFL Facility, Chatsworth Formation beds dip to the northwest at approximately 20 to 30 degrees . Well developed joint patterns are evident in outcrops . There are several major faults in the area which offset Paleocene and Upper Cretaceous rock units, including the Burro Flat s

II BNA01372584 H D M S E00620862 GROUNDWATER RESOURCES CONSULTANTS, INC.

Fault in the southwestern portion of the SSFL Facility and a Shear Zone which trends through the center of the SSFL Facility .

Fractures and joints (fractures with no detectable movement) are common at the SSFL Facility . The resulting fracture network has created a unique groundwater system .

HYDROGEOLOG Y

There are two groundwater systems at the SSFL Facility : 1) a shallow groundwater system (Shallow Zone) in the surficial alluvium and the underlying zones of weathered sandstone and silt stone/claystone, and isolated shallow fracture systems ; and 2) a deeper regional groundwater system in the fractured Chatsworth Formation . In some parts of the SSFL Facility the two systems appear to be hydraulically connected . The groundwater monitor well network is shown on Figure 4 .

The Shallow Zone is discontinuous in the area of the SSFL Facility .

Some portions are saturated only during and immediately following precipitation events . Depth to groundwater has generally ranged from a few feet to about 20 feet below ground surface and occurs under unconfined conditions . The saturated thickness generally ranges from less than one foot to as much as ten feet .

The principal water bearing system is the Chatsworth Formation . The permeability of the Chatsworth Formation is considered to be very low excep t

U B NA0 1 3]2585

HDMSE00620863 GROUNDWATER RESOURCES CONSULTANTS, INC .

along open fractures . Groundwater within fractures occurs under both con- fined and unconfined conditions . The saturated thickness is not known, however during 1990 the static depth to groundwater ranged from about 4 .5 feet to 345 feet .

The most prevalent contaminants detected in SSFL Facility groundwater samples have been TCE and cis-1,2-dichloroethylene (cis-1,2-DCE) . The presence of degraded groundwater beneath the SSFL Facility is primarily related to past rocket engine testing activities . ICE was used to flush hardware and engine thrust chambers and to clean other equipment .

GROUNDWATER OCCURRENCE AND QUALITY AT AREA I THERMAL TREATMENT FACILITY

The wells in closest proximity to the Area I Thermal Treatment Facility are Shallow Zone wells RS-6 (approximately 200 feet east) and RS-7 (approximately 400 feet southwest), and Chatsworth Formation well R0-3 (approximately 300 feet southwest) . Groundwater elevations in the area are slightly above 1,700 feet mean sea level (MSL) for the Chatsworth Formation . The groundwater elevation measured in RD-3 in September 1991 was 1,735 .9 feet

MSL, which is approximately 10 feet below ground surface . A map depicting

Chatsworth Formation water level contours based upon the September 1991 quarterly monitoring event is shown on Figure 6 . Chatsworth Formation groundwater flow in the vicinity of the Thermal Treatment Facility appears to be towards the north-northeast . Based on September 1991 groundwater contours, well RD-3 appears to be upgradient of the Thermal Treatment

Facility . The groundwater elevation measured in September 1991 in th e

II BNA0137258 6 H D M S E00620864 GROUNDWATER RESOURCES CONSULTANTS, INC .

Shallow Zone well RS-7 was 1,729 .4 feet MSL (approximately 4 feet below

ground surface) . Shallow groundwater in the vicinity of the Area I Thermal

Treatment Facility, if present, would appear to follow surface drainage and

flow southeast toward perimeter pond ( Figure 4) . In this case, Shallow Zone

well RS-7 would be downgradient of the Area I Facility, and Shallow Zone

well RS-6 cross-gradient . Well RS-6 has been dry since 1989 . It is not

known at this time whether shallow groundwater is present immediately

beneath the Area I Thermal Treatment Facility .

Groundwater sampling results indicate that low level concentrations

(less than 10 ~cgfl) of TCE, cis-1,2-DCE and trans-1,2-DCE are present in

both the nearby Shallow Zone and Chatsworth Formation wells . Table 4 shows the results of most recent sampling at each well . These compounds are the primary contaminants occurring in groundwater beneath the SSFL Facility .

Only ICE has been related to previous activities at the Area I Thermal

Treatment Facility .

FIELD SAMPLING PLA N

SAMPLING OBJECTIVE S

This SAP, with its specific components of the FSP and QAPP, were requested by the US EPA and CA DTSC in their correspondence to Rockwell (US

EPA, CA DISC, 1991) . The FSP provides guidance for all field work by detailing the activities to be conducted in the field by the project personnel . The format of the FSP is based upon the guidelines of the CA

DISC Scientific and Technical Standards for Hazardous Waste Sites draft document (California Department of Health Services, draft 1990) . The FSP is the body of this SAP and the QAPP is presented as Appendix A . The QAPP describes the quality assurance/quality control procedures used in the field and laboratory . The format of the QAPP is based upon the outline provided by the US EPA (US EPA, 1988) .

As part of the closure activities at the Area I Thermal Treatment

Facility, soil sampling and other site field activities will be conducted to achieve the following objectives :

• Assess the current physical features of the area, including

disposal sites and surface drainage ;

• Assess the soil conditions of former physical features which may

have been used in disposal activities ;

IIDImuimiiimIII immmumiu BNA0137258 9 HDMSE00620867 GROUNDWATER RESOURCES CONSULTANTS, INC .

• Delineate vertical and horizontal extent of soil contamination,

where present, and

• Determine the presence or absence of shallow groundwater in the

area .

The specific tasks to be conducted during field activities are discussed in this FSP . The tasks will be conducted in three phases . The first phase will include wipe and concrete sample collection from the current structures . The second phase will consist of a geophysical survey and the third phase will be soil sample collection . Following sampling activities a topographic map will be prepared . The current physical features and exact sample locations will surveyed by a California licensed surveyor and included on the map . Information regarding additional post-sampling tasks, including laboratory analyses, are contained in the QAPP (Appendix A) .

Prior to sampling activities, site reconnaissance will be conducted to identify and locate the current physical features of the Area I Thermal

Treatment Facility . Sample locations will be marked and revised appropri- ately .

STRUCTURE SAMPLING

In order to facilitate disposal procedures during closure, the metal and concrete structures present at the area will be sampled following the sampling methodology described in this document in the section entitled,

"Sampling Equipment and Procedures ." One wipe sample will be collected from

IIDImuimiiimIII imniumnmi BNA0137259 0 HDMSE00620868 GROUNDWATER RESOURCES CONSULTANTS, INC .

an interior wall of the metal cage and one wipe sample will be collected

from one of the standing metal pipes in the other concrete pad .

The two concrete pads will be cored and three concrete spall samples will be collected from each pad (total of six spall samples) .

GEOPHYSICAL SURVEY

Prior to soil sampling activities, a geophysical survey will be conducted to locate buried metallic objects such as utilities and containers and to identify areas of disturbed soil . If the geophysical survey results indicate that areas of potential contamination exist, the soil sample locations will be revised accordingly as discussed in the closure plan .

SOIL SAMPLING

Sample locations will focus on the current disposal sites at the Area

I Thermal Treatment Facility (burn cage, concrete pad, associated berms, and fire department burn pit), past physical features and the remaining area not included in known active or past disposal . 1€sha}low: groundwater is encounta'd. g soil sampling, a shallow zone monitor well will be constructed L£ the geophysical survey results indicate that areas of potential contamination exist or additional information becomes available regarding areas of usage or disposal, the sample locations may be revised .

SOIL SAMPLE LOCATION AND FREQUENC Y

Soil samples will be collected from three borehole locations i n each of the concrete pads and seven berm wall locations at the current disposal sites, from one to two locations at each of the former disposal sites, four from areas of debris or disturbed sediment as identified by Harding Lawson, and from eleven locations outside the former disposal sites . Proposed soil sample locations within each of these areas have been chosen randomly . A' total Qf 44 soil sampl e locations have been selected at this time . At every tenth location a split sample will be collected (4 total split samples) .

Sample locations are shown on Figure 7 . The eleven locations outside of current and former disposal sites are in areas which have no documented active disposal, yet may have been affected by activities at the Thermal

Treatment Facility and within the fire department training/demonstration facility on the west side of the Area I Thermal Treatment Facility . A portion of these samples will be collected from the area downgradient of the surface drainage . All drainage at the Area I Thermal Treatment Facility is directed towards the Perimeter Pond as indicated on Figure 7 and is eventually discharged from the site under Rocketdyne's NPDES permit .

The sample locations have been selected using a two dimensional random sampling method requested by the Rocketdyne Environmental Protection

Department . A numbered grid system has been developed for each of the former and current features, the fire department training/demonstration facility and the east side of the Area I Thermal Treatment Facility . The grid systems have been developed based upon the size of the individual are a

II BNA0137259 2 HDMSE00620870 GROUNDWATER RESOURCES CONSULTANTS, INC .

and the assumption that each feature is a separate stratum . A random number

table has been used to select locations . The random sampling method is

described in greater detail in Appendix B .

Three background soil samples will be collected from areas where the

alluvium is believed to have been unaffected by site activities . The

background sample locations are shown on Figure 8 .

Pursuant to the request of the US EPA and CA DTSC, split samples will be collected . Split samples will be submitted to BC Analytical, Inc . of

Glendale, California for the same analytical parameters as the primary sample (US EPA, CA DTSC, 1991) . The primary laboratory will be Analytical

Technologies, Inc . of San Diego, California . Both laboratories are certified by the State of California for analyses to be performed . Additional information regarding the laboratory procedures is contained in Appendix A

(Quality Assurance Project Plan) .

SAMPLE DESIGNATION

Samples will be designated sequentially based upon the sampling order .

The sample number will be BPZ-XX-YY wher e

BPZ = Burn Pit borehole number XX = Sequential sampling orde r YY = Depth of sample below ground surfac e

For example, BP2-05-0 .5 is the fifth sample collected from the Burn Pit area at a depth of 0 .5 feet below ground surface from the second borehole drilled during the project . Wipe and spall samples will not be identified by a

HDMSE00620871 GROUNDWATER RESOURCES CONSULTANTS, INC .

borehole designation or depth . All samples will be collected under the

Groundwater Resources Consultants , Inc . (GWRC) project number 8640, which

identifies the site to the analytical laboratory .

SAMPLING EQUIPMENT AND PROCEDURE S

Prior to sampling, the sample locations will be determined based on the sample location map presented as Figure 7 . Sample locations will be determined in the field using a compass and a measuring tape . Existing structures will be surveyed by a California licensed surveyor and located on a topographic map . A geophysical survey will be conducted to identify any buried structures and objects . All soil sampling activities will be carried out in accordance with the project Health and Safety Plan (Appendi x

C) .

As part of the closure plan the area will be cleared of brush and the miscellaneous surface debris which will be collected into a debris pile .

Materials in the debris pile will be steam cleaned and the rinseate colle.ted». A.o, .Qf the rinseate will be collected in laboratory- prepar e .p~awie and chilled . The debris pile will be also be sampled using,.j_dis lamtrowel and placed into laboratory-prepared sample jars .

It is anticipated that the debris will consist primarily of soil and small pieces of metal and concrete .

Wipe samples will be collected using sterilized gauze pads moistened with deionized water . The sampler will wear gloves without phthalates t o

V BNAO1372594 HDMSE00620872 GROUNDWATER RESOURCES CONSULTANTS, INC.

reduce the potential for cross-contamination from the glove material . Each wipe area will be approximately 10 centimeters square . The sample will be

collected by wiping the area once horizontally and once vertically . Each wipe will be placed in a laboratory-prepared glass jar, sealed and chilled .

One clean gauze pad will be submitted with each wipe sample as a laboratory

blank . A sample of the deionized water will also be analyzed to confirm

that no cross-contamination potential exists .

Concrete spall samples will be collected using a concrete corer . The core sample size will be adjusted to fit in an eight ounce glass sample jar .

Berm wall samples will be collected using clean brass sample tubes (6-inch long by 2-inch diameter) and a hand operated drive sampler . Soil borings will be drilled using hollow stem auger techniques .

The soil sampling procedures are detailed below .

1 . Sampling equipment will be cleaned using a non -phosphate cleaning

solution (e .g . Alconox® and distilled water) and a long-handled

scrub brush . Equipment will be tripled rinsed in distilled

water . Sample tubes will be new . Tubes will be cleaned and air

dried prior to usage . Glass sample jars will be laboratory-

cleaned prior to usage . New Teflon® lined bakelite lids will be

used with the glass jars . All drilling tools will be thoroughly

cleaned with a non-phosphate cleaning solution and rinsed before

commencing the drilling of individual borings and prior to

removal from the site . The augers will be decontaminated b y

steam cleaning . Fluids generated during decontamination will be

collected and stored on-site in 55 gallon drums pending sample analysis .

2 . An organic vapor monitor detector will be used to monitor vapors

at the sample location . Specific information regarding the usage

of detection equipment is contained in GWRC's Health and Safety

Plan and the Organic Vapor Monitoring Program manual .

3 . The drive sampler will be pushed six inches into the designated location in order to obtain a full soil tube sample .

For soil samples to be collected during drilling, the soi l

samples will be obtained using a split-spoon sampler driven for

18-inch intervals using a 140-pound hammer . The sail sampling

intervaLw.ill. be every two feet to a depth- of 20 feet unless

grourt itgt_or.bedrock is encountered at a shallower depth .

4 . The sample tube will be removed from the sampler and the outside

of the tube will be wiped with a clean paper towel . The ends of

the sample tube will be covered with Teflon® tape and plastic end

caps and sealed with clear packing tape . A completed sample

label will be affixed to the brass tube and the sample will be

immediately stored in a cooled ice chest .

The sample label will contain the following information :

BNA0137259 6 HDMSE00620874 GROUNDWATER RESOURCES CONSULTANTS, INC.

• company nam e • sample designation • project numbe r • date/time sampled • sampler's initial s

5 . A record of the sample will be made by the field geologist in the

project notebook . The record will include the sample designa-

tion, datejtime sampled, soil description and any additional

pertinent information .

6 . Equipment will be decontaminated between sampling locations as

detailed in Step 2 .

7 . Chain-of-custody documentation will be completed in the field and

will accompany the samples at all times . An example of the

chain-of-custody form is provided in Appendix A, Table A-2 .

8 . Drill cuttings will be transferred to 55 gallon drums and stored

on-site. pending analytical results . Soils will be disposed by

Rocketdyne in accordance with the appropriate regulations when

1abrZQr; :analysis has been completed . To prevent the possi-

bility of contaminant migration each borehole will be filled with

neat cemjit-to the surface . The cement will be poured from land

surface into the borehole . The borehole location will be

surveyed by a California licensed surveyor and its exact location

plotted on a site map .

BNA0137259 7 HDMSE00620875 GROUNDWATER RESOURCES CONSULTANTS, INC .

Soil samples from all locations will be screened in the field for organic vapors using photo-ionization detection instrumentation . The entire sampling program will be conducted by a field geologist under the direction and supervision of a California Registered Geologist . The field geologist will maintain detailed field notes of activities, as well as a geologic log of each boring .

If shallow groundwater is encountered , one boring will be converted into a Shallow Zone monitor well and two rounds of groundwater samples collected . The well construction techniques are described in Appendix D .

SAMPLE HANDLING AND ANALYSI S

Sample handling and analysis procedures include transferring samples to the analytical laboratory , designating the analytical parameters and providing for disposal of wastes generated during sampling .

Samples will be submitted to the analytical laboratory within 48 hours of sampling . Samples will be kept in cooled ice chests pending delivery to the laboratory . The analytical parameters, methodologies , sample preserva- tions and holding times are presented in Tables .5, 6 and 7 for wipe, concrete and soil samples, respectively . Tbe~waat.s awairtical parameters

W44m pie @I ' Chi"jnw+ daWnant material . If shallow groundwater is encountered, it is anticipated that groundwater samples will be analyzed for the same parameters as for the s oil s_ amales_(Table 7) . These parameters were chosen based upon documentation maintained by Rocketdyne regarding the wastes burned or disposed at the Thermal Treatment Facility during the period of 1961 through 1971 and 1982 through 1987 (Rocketdyne, 1980 through

1987) . The analytical parameters and Rocketdyne documentation are discussed in more detail in Appendix A . Laboratory analyses will be conducted in accordance with established protocol (US EPA, 1983 and 1986) . The laboratory project manager will be alerted to the project requirements and anticipated delivery times as part of the pre-sampling preparation . More information regarding the laboratory protocols is presented in the QAPP

( Appendix A) . Groundwater sampling procedures are outlined in Appendix D .

BNA0137259 9 HDMSE00620877 GROUNDWATER RESOURCES CONSULTANTS, INC.

Disposal of the fluids and soils generated during the sampling activities is the responsibility of Rocketdyne . Excess soil from samples will be disposed by the laboratory following completion of chemical testing .

POST-SAMPLING ACTIVITIE S

Following sampling activities, a topographic map will be prepared of the Area I Thermal Treatment Facility . Current physical features (the concrete pads, berms and firefighters' burn pit) and the sample locations will be surveyed by a California licensed surveyor and included on the map .

Upon receipt of all surveying and analytical reports, GWRC will prepare a report describing the implementation of the SAP, tabulation of data and discussion of the results .

BNA0137263 0 HDMSE00620908 GROUNDWATER RESOURCES CONSULTANTS, INC.

QA OBJECTIVES FOR MEASUREMENT

The goal of the quality assurance program is to ensure the production

of consistently accurate data, which is defendable as well as produced in

an efficient, timely and cost-effective manner . Procedures outlined in this

document are designed to ensure that the data collected are precise,

accurate, complete and representative . The program developed for soil

sampling is designed to ensure the validity and defensibility of the data .

The quality assurance program is composed of all activities to control field and laboratory errors and systems used to verify that field and analytical processes are operating within acceptable limits .

To achieve these objectives, field and laboratory and quality assessment/quality control (QA/QC) procedures are implemented . The laboratory practices correspond to procedures established by and for the US EPA and the

California Department of Health Services and adhere to accepted operating procedures in the industry . The laboratory subcontracted for this project

is Analytical Technologies, Inc . (ATI) of San Diego, California . This laboratory is certified under the California Department of Health Services laboratory certification program for analysis of hazardous waste .

In order to assess precision and accuracy of data, acceptance criteria have been established for various analytical methods . These criteria are

included in ATI's "Quality Assurance Manual" (ATI, 1990) . Detection limits for each analytical method will be dependent upon the constituents and thei r

HDMSE00620910 GROUNDWATER RESOURCES CONSULTANTS, INC .

SAMPLING PROCEDURE S

The sampling procedures are discussed in detail in the Field Sampling

Plan section of the Sampling and Analysis Plan text . The Sampling and

Analysis Plan includes information on the site background (site geology and hydrogeology), previous soil sampling efforts, the soil sampling strategy, sampling procedures and sample handling requirements . Implementing standard sampling procedures and documenting the field activities ensures accuracy and precision in field measurements and provides similar conditions for all samples and hence quality control .

Field sampling personnel are trained to perform all procedures included in the SAP . Field audits are conducted to ensure that field personnel are following sampling procedures .

SAMPLING CUSTOD Y

To establish the documentation necessary to trace sample possession from the time of collection, a chain-of-custody record will be filled out and accompany every sample . The record contains the following information :

• Sampler Name

• Sample Number

• Project Numbe r

• Date and Time Sampled

• Sample Type

• Type and Number of Containers

• Analyses Require d

• Destination of Sample s

• Signature/Company of personnel in chain of possession and inclusive dates of possessio n

Sampling personnel are responsible for the care and custody of the samples collected until they are transferred to the laboratory . To document sample possession, samples are accompanied by a chain-of-custody record .

When transferring samples, the individuals relinquishing and receiving will sign, date and note the time and condition of the samples on the record .

This record documents sample custody transfer . An example of the chain-of- custody form is provided in Table A-2 .

CALIBRATION PROCEDURE S

Calibration procedures are those procedures used to calibrate field equipment and laboratory analytical equipment . Field equipment used in soil

sampling that require calibration include the photoionization detector .

The health and safety equipment used to detect organic vapors is an HNU

PI-101 model photoionization detector . The equipment is calibrated daily using an isobutylene standard and is able to detect compounds with ionization potentials up to 10 .2 eV . Calibration of the instrument is performed

in nonhazardous ambient air .

Calibration procedures for organic vapor monitoring equipment is included in GWRC's "Organic Vapor Monitoring Program "which is kept on-site and at GWRC's office ." In addition the instruction manual provided by the manufacturer is kept with the instrument .

During groundwater sampling activities a Myron L . Company pH/conductivity meter and a thermometer are used to monitor groundwater . The pH/ conductivity meter is calibrated using standard solutions of known conductivity and pH . The instruction manual provided by the manufacturer is kept with the meter . The thermometer does not require calibration .

Analytical equipment to be used during laboratory testing are calibrated as part of the laboratory procedures . Specific information o n

ANALYTICAL PROCEDURE S

Laboratory services will be provided by Analytical Technologies, Inc . of San Diego, California which is certified by the State of California for analysis of drinking water and hazardous waste . Testing procedures are generally based on EPA's "Test Methods for Evaluating Solid Wastes,

Physical/Chemical Methods" (SW-846) and EPA methodologies from the US EPA test procedures manual (Methods for Chemical Analysis of Water and Wastes,

March 1979) or equivalent approved methods . The analytical parameters, methodologies and holding times are presented in Table 5, 6 and 7 of the

Sampling and Analysis Plan . The analytical procedures selected are based upon documentation maintained by Rocketdyne regarding the wastes burned at the Thermal Treatment Area during the period of 1961 through 1971 and 1982 through 1985 . As part of the review of materials disposed of or destroyed at the area, the materials were compared to the wastes listed in 40 CFR Part

261-33, and the California Code of Regulations, Title 22, §66261 .126

(Appendix XII) . Wastes listed in either federal or state codes are summarized in Table A-3 . The analytical parameters selected for the project include those wastes . The documentation of disposal activities during 1982 through 1985 is a series of internal letters prepared by Rocketdyne representatives regarding the types and quantities of materials disposed on specific dates .

INTERNAL QUALITY CONTROL

Every tenth sample or a minimum of one, shall be split in the field for submittal to a secondary laboratory for analysis . The secondary laboratory will be BC Analytical of Glendale, California (certified by the State of

California) . Results from the two laboratories will be compared .

In addition , background samples will be collected in the field at locations believed to be unaffected by site activities . The results will be compared to samples collected from the Area I Thermal Treatment Facility .

Laboratory quality control checks consist of general quality control and assessment procedures adapted to the specific operating conditions .

Quality control practices at the laboratory will include instrument calibration and continuing calibration verification , laboratory control samples, matrix spikes and surrogate additions and reagent /method blanks .

Laboratory control samples are generally EPA Quality Control Samples .

Results from the EPA samples must fall within limits which have been statistically established by the EPA through inter-laboratory studies .

APPENDIX B

TWO DIMENSIONAL RANDOM SAMPLING PROTOCO L

A two dimensional random sampling protocol was selected by the

Rocketdyne Environmental Protection Department to assess the soils at the

Area I Thermal Treatment Facility . Each of the former and current features, the fire department training/demonstration facility and the east side of the

Thermal Treatment Facility were considered as separate strata . Each stratum was divided into cells of equal dimensions . The cell sizes were approximately five feet square for the former and current features and fifty feet square for the fire department training/demonstration facility and the east side of the Area I Thermal Treatment Facility .

Cells were numbered subsequently starting in the upper left corner, to the upper right corner, down one cell, across to the left and so forth until all the cells were numbered . Certain cells were deleted from the numbering scheme . These included cells entirely outside of the former and current features, cells transacting feature perimeters which have more than fifty percent outside the feature, and cells which have rock or smaller grid cells composing most of the cell area . Sampling locations will be in the center of the selected cell .

Random soil sampling locations were selected using a table of 14,000 random units (Beyer, William H ., Editor, 1979, CRC Standard Mathematical

Tables : CRC Press, Inc ., pp 544 - 548) . A copy of the random number table

II BNA0137265 6 HDMSE00620934 GROUNDWATER RESOURCES CONSULTANTS, INC .

is presented as Table B-1 . Numbers were selected using the following

procedure :

1 . An arbitrary starting point was selected in the table, including

the column, row and positional digits . The number of positional

digits corresponded to the number of digits in the highest cell

number . For example, if the number of cells is 100, three

positional digits are needed .

2 . Starting at the selected arbitrary point, proceed down the column

until the first number in the column corresponds to a number in

the grid system . Each corresponding number is selected until the

desired number of sample locations are obtained .

3 . If a number is not identified in the initial column, the

procedure continues at the top of the next sequential column is

repeated as necessary .

Table B-2 presents the columns, rows, positional digits and selecte d

numbers .

Responsibilities - Health and Safety Information Office r

The Health and Safety Information Officer will serve as scientifi c advisor for the duration of the project, providing guidance on data interpretation and advice for appropriate levels of worker protection .

Responsibilities - Site Safety Officer

The Site Safety Officer will monitor the day-to-day compliance with this Site Safety Plan . He will provide technical assistance to project management on problems relating to work site safety . Safety officers will conduct periodic field safety inspections regarding existing or potential health and safety hazards and will note such conditions in the project notebook .

At any time unsafe work conditions are recognized , the Site Safety

Officer is authorized to stop work . Resolution of all on-site health and safety problems will be coordinated through the Project Manager with assistance from the Health and Safety Information Officer .

GENERAL HAZARD EVALUATION

The waste material consists of debris, concrete, soil and shallow groundwater potentially contaminated with various waste materials disposed by open burning . The materials were generally explosive and/or flammable .

C-3

I II B NA0 1 3]2fi6]

HDMSE00620945 GROUNDWATER RESOURCES CONSULTANTS, INC .

Known constituents of concern , their exposure limits, chemical properties and physical properties are presented in Table C-1 .

During the activities conducted and documented in the Hydrogeologic

Assessment Report, the principal groundwater contaminant detected in the vicinity of the Area I Thermal Treatment Facility was trichioroethylene

(Groundwater Resources Consultants , Inc ., 1987 ) . Due to the lack or low concentrations of other detectable constituents in adjacent groundwater wells, it is not anticipated that respiratory hazards will be encountered with the presence of shallow groundwater . It is anticipated that volatile or flammable constituents listed in Table C-1 will not be present in debris or soil due to the thermal destruction of materials . The types of materials which are more likely to be present are metals and ash residues .

As part of the closure plan a geophysical survey will be conducted prior to soil sampling to identify any buried objects or disturbed soil .

Positive results may indicate areas of potential contamination or containers of hazardous materials . The physical threat of uncombusted explosive or flammable materials is present at the area , however documentation maintained by Rocketdyne indicated disposal by open burning . The explosion potentia l is low because disposal was observed and the area has been subject t o grading operations frequently .

HEALTH AND SAFETY WORK PLAN

PRINCIPAL TASKS : BOREHOLE DRILLING, SOIL SAMPLING,

MEDICAL MONITORING

Workers should be found medically fit to participate in fiel d activities . Each worker should be familiar with the warning signs of heat stress, as discussed below , and should monitor co-workers as condition s warrant .

SAFE WORK PRACTICE S

The understanding of basic, precautionary concepts regarding persona l health and safety is essential for workers assigned to sites where chemical contamination is known or suspected to be present . These concepts are presented below:

1 . Eating, drinking , chewing gum or tobacco , smoking, or any practice which increases the probability of hand - to-mouth transfer of contaminated material is discouraged .

2 . The hands and face must be thoroughly washed upon leaving the

work area and prior to engaging in any activity indicated above .

C-5

BNA0137266 9 HDMSE00620947 GROUNDWATER RESOURCES CONSULTANTS, INC.

Showers should be taken as soon as possible after leaving the

work site at the end of the day .

3 . Any required personal protective equipment, appropriate to the

designated job function, must be worn by all personnel going on

site .

4 . When it is necessary for visitors to observe the field work, they

must be issued appropriate personal protective equipment,

informed about potential hazards, safety practices,

decontamination procedures and communication . Visitors will not

be allowed on site when air contamination is detected .

5 . Contact with surfaces/materials either suspected or known to b e contaminated shall be minimized or avoided if possible .

6 . Environmental samples, field equipment , and/or contaminated materials of any kind shall not be stored, or brought into office areas, or any area where food or beverages are stored or consumed .

7 . All storage and work areas shall be kept clean and free from

accumulation of materials that could cause tripping, fire,

explosion , or other hazards .

C-6

BNA0137267 0 HDMSE00620948 GROUNDWATER RESOURCES CONSULTANTS, INC .

8 . All personnel shall be familiar with safety procedures and

instructions contained in this Site Safety Plan .

9 . All employees are obligated to report and rectify unsafe wor k

conditions .

LEVELS OF PROTECTIO N

Personnel must wear protective equipment when work activities involve known or suspected atmospheric contamination, when dangerous vapors, gases, or particulates may be generated, or when direct contact with dermally active substances may occur . Respirators can protect lungs, the gastrointestinal tract, and eyes against air toxicants . Chemical-resistant clothing can protect the skin from contact with skin-destructive and skin- absorbable chemicals . Good personal hygiene limits or prevents ingestion of materials .

Protection levels designed to protect the body against contact with known or anticipated chemical hazards are divided into four categories according to the degree of protection afforded :

Level A Should be selected when the highest level of respiratory, skin, and eye protection is needed .

Level B Should be selected when the highest level of respiratory

protection is needed, but a lesser level of skin protection .

C-7

BNA0137267 1 HDMSE00620949 GROUNDWATER RESOURCES CONSULTANTS, INC .

Level C Should be selected when types of airborne substances are known,

the concentrations are measured, and the criteria for using air-

purifying respirators are met .

Level D Is worn on sites with no .respiratory or skin hazards . This is

primarily a work uniform providing minimal protection .

The level of protection selected is based primarily on :

- Types and measured concentrations of the chemical substances i n

the ambient atmosphere and their associated toxicity .

Potential or measured exposure to substances in air , splashes of

liquids, or other indirect contact with material due to the task

being performed .

In situations where the types of chemicals, concentrations, and possibili- ties of contact are not known , the appropriate level of protection must be selected based on professional experience until the hazards can be further characterized . At the Area I Thermal Treatment Facility, Level C protection is recommended initially, until ambient monitoring indicates that an increased or decreased level of protection is warranted . Chemical cartridges which provide protection against organic vapors in combination with a dust and mist filter will be worn .

C-8

BNA0137267 2 HDMSE00620950 GROUNDWATER RESOURCES CONSULTANTS, INC .

PERSONAL PROTECTIVE EQUIPMENT

The individual components of clothing and equipment must be assembled into a full protective ensemble to protect the worker from site-specific hazards while at the same time minimizing the hazards and drawbacks of the personal protective gear itself . Ensemble components based on the widely- used US EPA Levels of Protection are detailed for Levels C and 0 Protection below .

Level D Protection

1 . Personal Protective Ensemble

Required

- Safety boots/shoes

- Hardhat

optional

- Coverall s

- Safety glasses or chemical splash goggles

- Gloves

- Escape mask - Face shiel d

2 . Criteria for Selection ( Level D)

The use of Level D protection is permissible upon satisfaction of

these criteria : - No hazardous air pollutants have been measured in th e breathing zone .

C-9

EM II BNA01372673 HDMSE00620951 GROUNDWATER RESOURCES CONSULTANTS, INC .

Work functions preclude splashes, immersion, or potential for unexpected inhalation of any hazardous chemicals .

3 . Guidance on Selection Criteria (Level D)

Level D protection is primarily a work uniform . It can be worn

in areas where only boots can be contaminated, or there are no

inhalable toxic substances .

Upgrade from Level D to Level C Protection

Should environmental monitoring and site conditions indicate that Level

0 protection is no longer adequate, an upgrade to Level C protection will be required . The scope of work for this project does not include conducting field activities at Level B protection . Thus, an upgrade in level of protection would necessitate additional health and safety measures, including personnel training . The following brief description of Level C protection is not intended to address all requirements and ramifications of Level C protection .

Level C Protection

1 . Personal Protective Ensemble Required

- Half or full-face air-purifying respirator equipped with MSHA and NIOSH approved organic vapor/acid, gas/dust/mist combination cartridges or as designated by the Health and Safety Information Officer . - Chemical-resistant clothing (overalls and long-sleeved jacket ; hooded, one- or two-piece chemical splash suit ; disposable chemical-resistant one-piece suit) . - Inner and outer chemical-resistant glove s

C-10

limo II BNA01372674 HDMSE00620952 GROUNDWATER RESOURCES CONSULTANTS, INC .

- Chemical -resistant safety boots/shoes

Hardha t

Optional

- Coverall s

- Disposal boot covers

- Face shiel d

- Escape mas k

2 . Criteria for Selection (Level C) The use of Level C protection is recommended upon satisfaction of these criteria :

- Measured air concentrations of identified substances will be reduced by the respirator to below the substance's permissible exposure limit ( PEL), threshold limit value ( TLV), and/ or the concentration is within the service limit of the cartridge .

- Atmospheric contaminant concentrations do not exceed IDL H levels .

- Atmospheric contaminants , liquid splashes, or other direct contact will not adversely affect the small area of skin left unprotected by chemical -resistant clothing .

3 . Guidance on Selection Criteria (Level C l

Level C protection is distinguished from Level B by the equipment

used to protect the respiratory system, assuming the same type of

chemical -resistant clothing is used . The main selection

criterion for Level C is that conditions permit wearing air-

purifying devices . The device must be an air purifying

respirator (MSHA/NIOSH approved) equipped with filter

cartridge(s) . Cartridges must be able to remove the substances

C-11

M1V BNA01372675 HDMSE00620953 GROUNDWATER RESOURCES CONSULTANTS, INC.

encountered . Respiratory protection shall be used only with

proper fitting, training, and the approval of a qualified

individual . In addition, an air-purifying respirator can be used

only if :

- Oxygen content of the atmosphere is at least 19 .5% i n volume . - Substance(s) are identified and concentration(s) measured . - Substance(s) have adequate warning properties .

- Individual passes a qualitative fit-test for the mask .

- Appropriate cartridge/canister is used, and its service limit concentration is not exceeded .

An air monitoring program is part of all response operations when

atmospheric contamination is known or suspected . It is

particularly important that the air be monitored thoroughly when

personnel are wearing air-purifying respirators . Continual

surveillance using direct-reading instruments is needed to detect

any changes in air quality necessitating a higher level of

respiratory protection .

PROTECTION LEVEL RECOMMENDED FOR INITIATING WORK

Based upon the type of operations previously conducted in the area,

Level C protection is recommended for initiating work . The respiratory protection will consist of half or full-face respirators equipped with organic vapor/dust and mist combination cartridges (MSA model GMA-F, par t

C-12

A II BNA01372676 HDMSE00620954 GROUNDWATER RESOURCES CONSULTANTS, INC .

464023) . The respirator is not designed for organic vapor concentrations greater than 1,000 parts per million or dusts and mists having a Time-

Weighted Average (TWA) less than 0 .05 milligrams per cubic meter . Exposures to chemicals at concentrations above permissible limits are not expected, given the concentrations of soil and water contaminants found in previous investigations . The primary potential route of exposure may be off-gassing of contaminated soils or contaminated groundwater . A photo-ionization detector (HNU) will be used to monitor air quality during drilling and sampling operations . If airborne contamination at 5 ppm above background levels is detected on a continuous basis during field activities , an attempt will be made to identify and quantify the constituents to determine whether the level of protection should be upgraded . If no airborne contamination is detected, the respiratory protection may be downgraded to Level D at the discretion of the on-site Health and Safety Officer .

MONITORING EQUIPMENT AND PROCEDURES

The HNU monitor must be carefully inspected prior to work startup .

Failure of the HNU monitor to work or calibrate properly must be reported to the Project Manager immediately .

Proper use of the HNU ( with 10 .2 eV lamp) is described as follows . Calibrate prior to each day's activities, according to manufacturer's instructions . Record calibration in the HNU log book . Recalibrate after cleaning the lamp or when background levels drift . This instrument is sensitive to humidity and may require periodic lamp cleaning if it is humid .

C-13

R BNA0137267 7 HDMSE 0062 0955 GROUNDWATER RESOURCES CONSULTANTS, INC .

Initial monitoring will be performed at monitor well installation /sampling locations . Record measured levels in the log books . If readings are above background , monitor continuously and record readings every 30 minutes .

ACTION LEVEL S

A continuous ( 2-3 minute ) reading of 500 ppm above background in the breathing zone requires an upgrade to Level B, or evacuation , until readings subside .

HEAT STRESS

Heat stress is probably one of the most common ( and potentially serious ) illnesses during field operations . The potential for heat stress is dependent on a number of factors, including environmental conditions, clothing , workload, physical conditioning , and age . The effects of heat stress can range from mild symptoms, such as fatigue , irritability, and decreased mobility, to death . The body ' s response to heat stress include the following :

I . Heat Rash : A result of continuous exposure to heat and humidity, heat rash decreases the body ' s ability to tolerate heat .

2 . Heat Cramps : A result of profuse perspiration with inadequate fluid intake and chemical replacement , heat cramps are signalled by muscle spasms and pain in the abdomen and the extremities .

3 . Heat Exhaustion : A result of increased stress on various organs . The signs of heat exhaustion include shallow breathing ; pale, cool, moist skin ; profuse sweating ; dizziness and lassitude .

C-14

IIDImuimiiimIII immi BNAOI 37267 8 HDMSE00620956 GROUNDWATER RESOURCES CONSULTANTS, INC .

4 . Heat Stroke : The most severe form of heat stress, heat stroke must be relieved immediately to prevent severe injury or death . The signs of heat stroke are red, hot , dry skin ; no perspiration ; nausea ; dizziness and confusion ; strong, rapid pulse ; coma . The body must be cooled and medical attention sought immediately .

All personnel should be able to recognize the symptoms of heat stress .

Should an individual manifest any symptoms of heat stress, the affected

person will be assisted to seek shade , drink plenty of fluids, and seek medical attention if necessary .

Personal protective equipment may place a worker at considerable risk of developing heat stress . Equipment and clothing may severely reduce the body's normal ability to maintain equilibrium by restricting the body's heat loss mechanisms . Furthermore , the bulk and weight of protective equipment increase energy expenditure . Therefore , when selecting outer protective clothing, the intent of protecting against chemical splashes or other potential skin exposure must be carefully weighed against the added heat stress that may be associated with the bulk and impermeability of the suit .

Tyvek suits will be worn as part of the Level C protective equipment .

Although Tyvek offers little or no protection against hazardous liquid or vapor contaminants , it does protect against particulate contaminants and other nuisances, and reduces direct contamination of inner garments . It is lightweight and not as conducive as other protective materials to heat build- up, but it may contribute to the potential for heat stress . Given these conditions it is likely that Level C protective clothing may increase the potential for short term health hazards . Therefore , if heat stress

C-15

IIDImuimiiimIII immi BNA0137267 9 HDMSE00620957 GROUNDWATER RESOURCES CONSULTANTS, INC .

occurs, short-term site evacuation may be the most prudent means of dealing

with the situation . This decision should be made by the Site Safet y Officer .

WORK EXCLUSION ZONES

Three zones will be established during field activities : exclusion

zone, contamination reduction zone and support zone . The exclusion zone will be established within a 25 foot radius of the sample location . All

personnel entering this zone will be required to wear the personal protective equipment specified by the Site Safety Officer . The zone will be designated by flags or caution tape . Primary activities will be established on the upwind side of the zone . A windsock is currently present at the Area I Thermal Treatment Facility .

The contamination reduction zone will be established outside of the exclusion zone . Equipment and personnel will be decontaminated in this zone . The width of the zone will be approximately 10 feet . It is not anticipated that any area size limitations will be encountered .

The support zone will be established outside of the contamination reduction zone . Personal protective equipment will not be required in this zone .

C-16

BNA0137268 0 HDMSE00620958 GROUNDWATER RESOURCES CONSULTANTS, INC .

FIRE PROTECTION AND PREVENTION

The elements of an adequate fire protection and prevention program include :

- Proper site preparation and safe storage of combustible and flammable materials .

- Coordination with Rocketdyne Fire/Security Personnel .

- Adequate job-site fire protection .

Fire Fighting Equipment and Requirement s

Fire extinguishers shall be provided and maintained by the drilling sub-contractors . In addition, fire extinguishers shall be stored in th e GWRC vehicle .

EMERGENCY INFORMATIO N

In the Event of Personal Injury

Emergency first aid will be applied on site as deemed necessary .

Transport the individual to the Control Center/Fire Station if needed .

First-aid kits will conform to standards established by the American

Red Cross . The kits shall consist of a weatherproof container with sterile, individually-sealed packages for each type of item . It will be the responsibility of the Site Safety Officer to confirm that the first-aid kit is fully equipped .

C-17

IIDImuimiiimIII DDiiimmiimmmi BNA0137268 1 HDMSE00620959 GROUNDWATER RESOURCES CONSULTANTS, INC.

In the Event of Adverse Weather Condition s

In the event of adverse weather conditions , work may be suspended to protect the health and safety of GWRC and performance contractor workers .

Some issues to be considered prior to determining if work should continue in the event of adverse weather conditions are :

- Potential for heat stress ;

- Inclement weather -related working conditions ;

- Limited visibility ;

- Potential for electrical or dust storms .

Emergency Number s

SHALLOW MONITOR WELL CONSTRUCTION AND SAMPLING

If shallow groundwater is encountered, one shallow monitor well will be constructed within the hollow stem augers . The diameter of the borehole will be approximately ten inches . The borehole will be cased with four-inch

Schedule 40 flush threaded polyvinyl chloride (PVC) casing with approximately 10 feet of slotted (0 .020 inch opening) Schedule 40 PVC casing placed on the bottom . After the casing has been placed a filter pack consisting of Monterey No . 3 sand or equivalent shall be poured from land surface to approximately five feet above the PVC screen . Approximately one foot of bentonite pellets shall be placed on top of the filter pack . Cement grout shall be poured from the top of the bentonite to land surface and a locking steel vault will be installed . The casing shall be equipped with PVC slip caps on the bottom and top . General procedures for sampling monitor wells are described in the following text .

iimmuimiiim~uiiimmiuummu BNA0137269 5 HDMSE00620973 GROUNDWATER RESOURCES CONSULTANTS, INC .

GROUNDWATER SAMPLING PROCEDURES

Groundwater sampling procedures include those procedures for measuring water levels, purging wells prior to sampling, measuring field parameters

and collecting samples .

WATER LEVEL MEASUREMENT

Water level measurements will be obtained from wells using electric sounders . The depth to water, in feet below the measuring point, the date of measurement and the calculated water level elevation will be recorded on the water level data field log . Water level measurements will be recorded to the nearest 0 .01 foot .

WELL PURGING

Monitor wells will be "over-purged" prior to the collection of the first round of water samples . Over-purging of the wells, in general, will consist of pumping each well for a period of about three to four hours followed by one to two hours of water level recovery . Temperature, pH and electrical conductance ( EC) will be measured in discharge water and recorded at least once per hour . Specific purging procedures will vary according to well capacity . The method used to purge a low yield well [less than 1 gallon per minute (gpm)) will differ from the method used to purge a normal yield well (at least 2-3 gpm) .

0-2

BNA0137269 6 HDMSE 0062 0974 GROUNDWATER RESOURCES CONSULTANTS, INC.

The method of over-purging a low yield well, such as a Shallow Zone well, will consist of initially pumping or bailing the well at about 3-5 gpm until the pumping level is at the pump intake . Once the pumping level approaches the pump intake, the discharge rate will be reduced to about one gpm . If the well sustains 1 gpm, pumping will continue for a period of one to two hours . If the well does not sustain one gpm, pumping will be stopped . The following day, the well will again be pumped at 3-5 gpm until the pumping level approaches the pump intake . This procedure will be repeated on the following day in order to purge the well three times .

Following the third day of purging, water samples will be collected from the low yield well . Water level recovery will be monitored after the third day of purging .

Over-purging of a normal yield well will consist of pumping the well at a rate sufficient to cause at least 20 feet of drawdown during a period of three to four hours . After purging the well for three to four hours, samples would be collected, the pump would be turned off, and water level recovery measured for a period of three to four hours .

MEASUREMENT OF FIELD PARAMETERS

Field parameters temperature, pH, and EC will be measured prior to collection of all water quality samples . Field instruments will be calibrated daily prior to use according to manufacturer's instructions .

Field parameters will be recorded on sample collection forms .

D-3

IDm B NA0 1 3]2fi9]

HDMSE00620975 GROUNDWATER RESOURCES CONSULTANTS, INC .

After final purging, water samples will be collected using a disposable polyethylene bailer . Samples will be placed in laboratory prepared bottles .

All samples will be labeled with project number, well or sample location, sample number, collector's name, collection date, any special instructions and the analysis to be performed . Samples will then be sealed, packaged and stored on ice or blue ice in plastic ice chests . Letters of transmittal, chain-of-custody documentation and laboratory analyses schedules will be prepared at the end of each sampling event and placed in a waterproof bag .

The ice chest containing samples and sample documentation will be clearly labeled and sealed to prevent tampering during transport to the laboratory .

The following shall be added :

Equipment and structures will be steam-cleaned . A _steam...cleaning .area shall be constructed for the cleaning of equipment, movable d.bris . This area shall be bermed and covered with plastic sheeting in order to contain the rinsate . Immovable structures shall be steam-cleaned and the rinsate captured with plastic covered berms .

Upon completion of the steam cleaning, the rinsate shall be collected in 55 gallon drums by pumping, then , sailed . If analysis of the samples show that the rinsate is hazardous, it shall be managed as hazardous waste .

Upon completion of the above operations, s mn]Ps frnm rhP ~nlactir eh e ttj g and berms shall „tzc_taken . The plastic sheeting shall be removed, the berms shall be brought down, and both shall be containerized. If analyses show that the plastic sheeting and berms are hazardous, it shall be managed as hazardous waste .

The 55-gallon drums containing hazardous rinsate, and the containerized hazardous plastic sheeting and berms shall be subject to labelling requirements in accordance with 22 CCR 60262.43 (f) . Containers holding hazardous wastes shall be stored for 90 days or less. If for any reason, storage time shall exceed 90 days, Rockwell will notify and seek prior approval from the DTSC before doing so .
