Cateqorical Exclusion for Sampling SWMU CPP-45: CPP-621 Chemical Storaqe Area Spills. r. L. L- V

Unit Description/HistorY

Various acids (HC1, HNO3, HF, and H2SO4) and aluminum nitrate are stored in large metal and fiberglass tanks encircled by earth berms south of CPP-621. The storage area consists of 8 tanks, 2 open bottom limestone pits and six French drains (see Figure 1). During the history of operations in the CPP-621 area, five releases are known, or are suspected to have occurred. A summary of the pertinent areas and known or suspected releases within the CPP-621 area is given below.

1. Hydrofluoric Acid (HF) tank (VES-CS-169) was surrounded by an open bottom pit (CPP-727) which contained limestone to neutralize the contents of the HF tank if the acid and limestone were contained in a completely mixed tank. VES-CS-169 has a capacity of 9,700 gallons. In the past, a steam condensate drain from building CPP-621 discharged to a small (approximately 11 x 1') collection pit on the north wall of CPP-727.

Prior to 1986, any leakage in this pit would have gone directly to the soil. In 1986, a floor was constructed in CPP-727 to contain releases, and the overflow from VES-CS-169 was rerouted to an overflow collection container.

CPP-727 received HF and potentially HC1 and H2SO4, from past releases from the tank overflow and vent lines. One HF spill is known

C.Y\

REF .4 5 _y_1149-0-rGS to have occurred (approximately 15 L in 1988), and numerous small spills are suspected. In addition, steam condensate from building CPP-621 drained into a small pit located at the foot of the north wall.

2. The HCL (VES-CS-167) and H2SO4 (VES-CS-164) tanks were surrounded by an open bottom pit (CPP-757). Each of the tanks has a 4,000 capacity. The vent and overflow lines from VES-CS-167 and -164 drained to CPP-727, however, accidental spills could have drained directly to the soil in CPP-757. These acid tanks have been taken out of service and removed from the unit.

CPP-757 received a release of approximately 1,136 L of H2SO4 during a pipe flushing operation in 1988. In addition, CPP-757 may have received small releases of HCL and H2SO4 prior to the decontamination and decommissioning of VES-CS-164 and -167.

3. Three aluminum nitrate tanks (VES-CS-101, -102 and -152) are located south of building CPP-621 and west of the the chemical trench. VES-CS-101 and -102 have a 8,000 gallon capacity and VES-CS-152 has a 18,400 gallon capacity. Two nitric acid tanks (VES-CS-100 and -151) are located south of building CPP-621 and east of the chemical trench. VES-CS-100 has a 34,100 gallon capacity and VES-CS-151 has a 18,400 gallon capacity. Prior to the construction of the chemical trench in 1986, the tanks were surrounded by earthen berms and each tank had a French drain used for collecting overflow discharges. In 1986, secondary containment was constructed around the tanks.

In March 1982, HNO3 was delivered to tank VES-CS-100. Approximately 1,200 gallons of acid overflowed to the French drain and eventually over the ground. The soil in the spill area was sampled at the time of the spill and was found to have a pH of approximately 10. The acid was not contained since the berm had been removed for construction of c c Draft: 8/2/90: GS the chemical trench. The overflowed acid pooled along side the concrete wall being installed for the pipe trench, south of VES-CS-151. Several thousand pounds of soda ash was applied to neutralize the acid and the contaminated soil was excavated for disposal.

4. A sludge pit is located adjacent to the northeast corner of building CPP-621. The sludge pit was installed when the aluminum nitrate tanks were installed. Prior to approximately 1986, deliveries of aluminum nitrate were filtered to remove impurities. The impurities were then sent to the pit. After 1986, all aluminum nitrate ordered has been filtered prior to delivery and the use of the pit was discontinued.

No releases of hazardous waste have been documented to the sludge pit, however, sampling conducted by the University of Utah Research Institute (UURI) indicate elevated levels of Hg.

5. Building CPP-1614 is a corrugated metal building located adjacent to VES-CS-151 and pit CPP-757. The building houses pumps used for transferring H2SO4 from VES-CS-164 to the FAST facility (CPP-666).

A release of approximately 86 L of H2SO4 is known to have occurred in building CPP-1614. The release was due to a pipe leak which occurred in 1986.

Preliminary Sampling

Preliminary sampling was conducted by the University of Utah Research Institute, Murry, UT in 198_i"The areas sampled are shown in Figure 2. The preliminary analysis indicate that the hazardous wastes/constituents were found above background levels in the following areas: o mercury was above background in the three aluminum nitrate French S/2 3,41/90: GS drains. The aluminum nitrate French drains were remediated in 198_. o fluorides were above background in CPP-727; o lead is above background in the chemical trench.

No hazardous wastes/constituents were found above background levels in CPP-757.

Since the UURI sampling program was preliminary in nature, additional sampling will be required to verify that no contaminated soils are present.

Environmental Concerns

Progosed Actions

Sampling will be conducted in containments CPP-727 and CPP-757. Initially, 3 boreholes will be drilled in each containment to a depth of six feet. Each hole will be sampled at 0-2, 2-4 and 6-6 feet. At the completion of sampling, each borehole will be backfilled with clean soil taken from the clean construction soil pile located south of the ICPP fence.

A11 sample analyses will be conducted in accordance with the methods outlined in EPA's "Test Methods for Evaluating Solid Wastes" (SW-846). Soil samples collected from CPP-727 will be analyzed for fluorides, TCLP metals and pH. Soil samples collected from CPP-757 will be analyzed for sulfides, chlorides, TCLP metals and pH. One sample from each containment will be analyzed for 40 CFR 261, Appendix VIII constituents. Draft: 8/2/90: GS If analyses indicate that contamination is present at the six foot level in either containment, a decision will be made to either drill additional FV boreholes to collect samples at greater depths, or to defer further sampling until required by the COCA or Interagency Agreement schedule.

Contractor Environmental Organization Review

A categorical Exclusion is appropriate for the described activity. A categorical exclusion should be granted on the basis that the proposed activity is a Site Characterization and Environmental Monitorinq activity as outlined in the list of categorical exclusion in the Federal Register, Volume 55, number 67, page 13066, April 6, 1990.

I. UNIT CONDITIONS

A. General Information

The Idaho Chemical Processing Plant (ICPP) acid storage area, located at CPP-621, is shown in Figure 1. The acid storage area has six french drains and two open-bottomed containment areas which are filled with limestone (constructed to be used in the event of an overflow or spill). This closure plan will address the methodology used to eliminate the french drains and open-bottomed containment areas, in addition to the proposed plans for controlling overflows and/or spills once the drains are closed.

The acid storage area (CPP-621) consists of eight tanks. There are two nitric-acid tanks - CS300 capacity of 34,100 gallons and has one french drain;--a6d 013451 has a capacity of 18,400 gallons and has one french drain. The sulfuric acid tanks, CS-164 and CS-167, each have a capacity of 4000 gallons, giving a total capacity of 8000 gallons. The two tanks share a limestone-pit containment area where there are no french drains. The hydrofluoric acid tank, CS-169, has a capacity of 9700 gallons and has one french drain with an open- bottom limestone pit containment area. This tank was recently constructed as part of the FAST facility and is surrounded by a limestone pit which is approximately 20 feet by 15 feet by 6 feet. Each of the aluminum-nitrate tanks, CS-101 and CS-102, has a capacity of 8000 gallons and(eactOlas a separate french drain. Another aluminum- nitrate tank(IlaS a capacity of 18,400 gallons and has one french drain. Thus, a total of six french drains and two open-bottom limestone-pit containment areas must be closed.

The actual quantity of acid which has overflowed or spilled into the h CiL drains is unknown; however, the quantity is believed to be smell. c-0 c Sampling of the soil has not previously been accomplished. The average pH of soil at the ICPP has,,19egft_found to be approximately 10. This fact, in conjunction with thettreatment of the.acid in limestone pits, leads us to believe thatvehtsoil will ribt\ be found to be contaminated with hazardous wastes

n•A ' ?,t Qer o

B. Schedule of Partial Closure

To reduce the likelihood of acid flowing into the soil through any of these french drains or limestone pits, WINCE) has initiated a policy whereby no tank is filled to more than 80 percent capacity. This administrative control has eliminated any acid disposals that might occur as a normal mode of operation.

C. Maximum Amount of Waste in the Unit

It is believed that the waste soil derived from the closure of the acid storage area will consist of hazardous waste. Soils will be analyzed for pH, sulfates, and fluorides. There are no indications that radioactively-contaminated soils will be found. However, due to the nature of operations at the ICPP, soils will be analyzed for radionuclides. In the unlikely event that mixed waste is found, the waste will be packaged and sent to a permitted storage facility at the INEL. However, if the soil is acidic and has no other hazardous characteristics or constituents, it will be neutralized and disposed of as backfill. The maximum amount of hazardous waste is believed to be relatively small due to the use of limestone, the pH of the soil, and the rarity of overflows or spills from the storage tanks.

D. Inventory of Auxiliary Equipment

Auxiliary equipment which may need to be decontaminated and/or disposed of will include old piping, french drains, and miscellaneous equipment. All equipment will be analyzed for hazardous material and radionuclides. If the equipment is found to be contaminated with hazardous wastes, then the equipment will either be treated with a caustic solution to neutralize it, or it will be transported to an off-site TSD facility. If the equipment is found to be radioactively contaminated, then it will either be decontaminated on site or sent to the Radioactive Waste Management Complex (RWMC). In either event, all procedures and guidelines will be adhered to throughout the process of decontamination and disposal or storage.

E. Schedule of Closure

Figure 2 provides a milestone chart for the closure of the acid storage area french drains and open-bottom limestone-pit containment areas. A new project scheduled for ICPP involves the construction of containment vaults. The new containment vaults will be constructed to meet the specifications of the regulations under RCRA (40 CFR 260-265).

F. Estimated Cost of Closure for Unit

This estimate assumes the worst case to include a possible mixed and/or radioactive waste in addition to hazardous waste. $K

II. DECONTAMINATING THE UNIT

A. Area of Unit with Potential Soil Contamination

The potential contamination should be limited to the soil beneath each tank to include the french drains.

EPA-approved field procedures will be used to collect representative samples by qualified and trained personnel. Also, vadose-zone- monitoring may be conducted to determine the extent of releases. WINCO or other laboratory facilities, with appropriate quality control and quality assurance programs, will use EPA-approved laboratory procedures to quantify the presence or absence of hazardous materials. These samples will be analyzed for: pH, fluoride, sulfate, EPA EP- toxic materials, and radionuclides. If significant levels of contamination exist in any sample, then additional sampling and analysis will be performed to determine the degree and extent of contamination. This information will be used to estimate the volume of contaminated soil. All contaminated material will be removed and sent to an off- site TSD facility. Contaminated soil will not be disposed of on site. If mixed radioactive waste is identified, it will be removed and sent to a permitted storage facility at the INEL.

B. Equipment Requiring Decontamination

If the soil is found to be hazardous and/or mixed waste, then removal will be performed. All equipment used to perform this task will require decontamination. A11 contaminated equipment will be placed in a stainless-steel pan and decontaminated. A11 wash water and/or solvents will be disposed of as required according to RCRA requirements. A11 solid waste generated during decontamination operations will also be disposed of according to RCRA requirements.

III. GROUNDWATER MONITORING

Since all soils found to be contaminated will be removed and/or treated in place, long-term groundwater monitoring will not be required. How- ever, short-term vadose-zone-monitoring may be performed as part of the unit characterization to evaluate the extent of the release from this unit. O C: IV. CLOSURE CERTIFICATION -a An independent, professional engineer will verify that every major step of the closure process is completed in accordance with the approved plan and will certify that closure is complete. Closure certification will not be necessary if all waste is transported off site to an EPA- approved TSD facility. Figure 2 Closure Schedule for ICPP Acid Storage Area (CPP-621)

You are probably aware of the environmental concerns with discharge of chemicals to "French drains" at the ICPP. Management is committed to eliminating all of this type of drain as soon as possible.

One of these French drains, specifically a sludge pit, receives solution from aluminum nitrate filtering operations at CPP-621. Currently, a maintenance package is being formulated to isolate the filtering vessels and piping from the sludge pit. As a result, no method is available for filtering aluminum nitrate during the second and third cycle operation.

I propose to eliminate the requirement for filtering aluminum nitrate at the ICPP and I request your concurrence based upon the fact that the aluminum nitrate furnished by the supplier is pure enough for use as is.

The aluminum nitrate that is received is filtered by the manufacturer before it is loaded for shipment. The filter media used is diatomaceous earth, and for all purposes, is the same that is used in the CPP-621 filtering operation. Samples of the bulk receiving tank solutions (unfiltered) show that the undissolved solids (UDS) are in the order of 3.08 micro grams per milliliter of solution. Samples of the solutions in the filtered tanks show the undissolved solids to be approximately 3.16 micro grams per milliliter. The sample results indicate that filtering of the bulk aluminum nitrate solution at the ICPP is not needed.

(VV) Westinghouse Idaho Nuclear Company. Inc. Mr. J. A. Rindfleisch Page 2 ECN-01-86 March 13, 1986

Furthermore, all of the feed tanks where aluminum nitrate solutions are fed into the process have in-line filters installed.

I request that you evaluate this information and my proposal to eliminate any future filtering of aluminum nitrate at the ICPP. I need your response by March 18, 1986 so as not to adversely affect the second and third cycle operation.

o cn 1.0 Introduction

This report documents the removal and verification sampling of mercury contaminated soils from french drains located at the

Chemical Storage Area (CPP 621) of the Chemical Processing Plant

(CPP). The complex is managed by the Westinghouse Idaho Nuclear

Company Inc. (WINCO). Mercury contaminated soils had previously been identified as a result of an initial site characterization

(reference 1) conducted by the University of Utah Research

Institute (UURI).

2.0 Remediation Procedures

Two excavations were required to remove the contaminated soils. The bulk of the soil was removed with a backhoe fitted with a flat plate welded across the teeth of the bucket to prevent cross contamination of adjacent soil. The locations of the excavations are shown in Figures 1 and 2. Their size and depth was limited by the presence of aluminum nitrate tanks adjacent to the drains. During the excavation, shoring requirements for tank stability and for workmen's safety were closely monitored by site engineers and safety personnel.

The excavation of the soil was conducted in four steps.

1. Non-contaminated soil was excavated to a depth of 2'6".

This depth was within one foot of the bottom of the drains. The

1 o o CO NI excavated material was stockpiled for future use as backfill. o Cr, The clay pipes that were used for the french drains were broken up and placed into drums. A plywood sheet wrapped in visqueen was placed over the area where the drain was located in order to cover the potentially contaminated exposed surfaces. After these areas were covered, the surrounding area was excavated to remove loose soil and to widen the excavation prior to removing the potentially contaminated material.

2. Potentially contaminated material between 2'6" and 6'6" directly under the drains, and to 5'6" peripheral to the drains, was excavated with the backhoe and placed directly in drums.

Excavation of the soil below 2'6" proceeded in increments of 4 to

The drums were placed on visqueen and a large plastic funnel was used to preclude the spreading of potentially contaminated soil. The visqueen was removed and drummed after each set of drums were filled. The drums were moved by crane onto pallets for further processing and labeling.

3. After both holes were excavated, the backhoe bucket was again decontaminated to insure that potentially clean material remaining in the pits was not contaminated with soils from the bucket. The excavations were deepened an additional 1'6" to 2' and the removed material was placed onto clean visqueen and stockpiled. In order to insure the safety of the workers, the backhoe was used to remove the final layer of potentially contaminated soil from the north pit which was excavated to

6'10". The south pit was deepened to a depth of 7' with

2 decontaminated shovels. The maximum depths of the excavations

were dictated by the need to insure the stability of the storage

tanks.

3.0 Verification Sampling Procedures

Soil samples were taken from the excavated material, the

walls and bottom of the excavation, and from a depth of 2' below

the excavations to verify that the contaminated soil had been

removed. A11 samples were collected by qualified personnel. The

sampling, sample handling, and decontamination procedures

followed during the collection of the soils are described in the

Quality Assurance Sampling Plan prepared for this project

(reference 2). Soil sample locations are given in Table 1.

4.0 Analytical Procedures and Results

The soil samples were analyzed for percent moisture, pH,

nitrate-nitrogen (NO3-N), and mercury (Hg) by the University of

Utah Research Institute (UURI) located in Research Park at 391

Chipeta Way, Suite A, Salt Lake City, Utah. This laboratory is

certified by the State Health Laboratory, Bureau of Laboratory

Improvement, for the required analyses. Utah is a "Primacy"

state in which EPA RCRA programs are managed at the state level

by authorized state agencies.

The analytical results are presented in Table 1. Nitrogen

values are given in parts per million (ppm), Hg values in parts

per billion (ppb).

3 CD o Cr) 00 Background concentrations of Hg and NO3-N were determined on O Cr) samples taken from the area around the CPP complex. (reference

1). A summary of the background data (mean, standard deviation and mean + 2 standard deviations) is given in Table 1. For comparison the Hg contents of soils developed over volcanic rocks typically ranges from 10 - 180 ppb and averages 50 ppb (reference

3).

5.0 Data Quality

The accuracy and precision of the analyses were determined from a statistical evaluation of the quality control samples.

Accuracy data were obtained from the analysis of standard reference materials, spiked field samples and standards analyzed along with the project samples. Precision data were obtained from duplicate analyses of field samples and standards analyzed with project samples. Control limits for accuracy and precision are nominally established by the EPA to be equal to the mean + 3 standard deviations. Quality control data for the analyses are contained in Appendix 1. These data indicate that the analyses fall within acceptable limits. A summary of the precision and accuracy data for the analyses is presented in Table 2.

Soil samples are heterogeneous and thus present inherent analytical problems. Often very small particles of a particular contaminant may not be present uniformly throughout the sample causing anomalies in data which must be verified through addi-

4 o o CD tional analysis. The UURI Laboratory performed multiple analyses I\D o in order to confirm the accuracy of its reported data. m

6.0 Evaluation of Results

The following conclusions can be drawn from a comparison of the analytical data with the background analyses:

1. Soil excavated from the northern pit has Hg contents greater than the background values.

2. The average Hg concentration of unexcavated soil is

<58.3 ppb. This value is approximately equal to the background mean + 2 standard deviations and is within the range of Hg contents of soils developed over volcanic rocks.

3. Repeat analyses of the samples indicate that the Hg is heterogeneously distributed in the soil.

4. No systematic variation in the Hg content of the unexcavated soil is apparent.

5. The NO3-N contents of the soils are slightly elevated above the background values, suggesting some contamination of the soil by either nitric acid or aluminum nitrate. SAMPLE AREA

Subject: Environmental Sampling for the Secondary Containment Vaults Project

Attached plaage find the chronology of events that you requested concerning the Secondary Containment Vaults Project Environmental Sampling. It is felt that the Sampling Plan that we have outlined is the hest possible to ensure a Sampling and Closure Plan which would be acceptable to the Environmental Protection Agency (EPA). This plan is based on WINCO's interpretation of the regulations and discussions with groups who have surressfully completed Sampling and Closure Plans for similar areas. Unless guidance is received from EPA as to what the minimum requirenents will be for the closure plan, we feel that we must continue to piupose a detailed sampling plan.

It has been proposed that the sampling be conducted concurrently with construction. Sampling concurrent with construction would be a very dangerous option for both the project schedule and budget. Unless the extent of amtamination is known, if any, the bid package cannot be adequately prepared to cover all excavation required for clPan-up. The time for sampling, analysis, and clean-up would be very difficult to bid and more than likely result in delay charges. This would dramatically impact both the project budget and schedule. Impacts on the project schedule could be quite garious becauPP of the limited window available for this construction area and the fact that it will not occur again within the next few years. There are also safety concerns for the construction personnel working with soil in which the condition is unknown. I feel it is very unwise to conduct all sampling concurrently with construction because we will open ourselves up to a great many problems.

Attachments CYY ACTIVITIES ON c P-621 EVALUATION TO DATE

08/13/86 Discussed characterization of CPP-621 Area with Montana Tech and University of Utah Researdh Institute (UURI).

08/18/86 Montana Tech called to discuss their capabilities for the characterization then indicated that they did not have the QA documentation or required sampling equipment.

08/22/86 Further discussions with UURI on sampling plan.

08/26/86 UURI visits CPP to inspect project area and requests underground line drawings.

08/28/86 Mailed out underground line drawings to UURI.

09/08/86 Meeting conducted with Wendell Random, Jeff Ruffner, George Buker, Tony Matule and Joan Poland to discuss Secondary Containment Project impacts and characterization.

09/08/86 Preliminary Scope of Work received from UURI who estimated that $138K would be required to complete a comprehensive characterization of the area.

09/09/86 M-K Boise Engineering visited CPP to discuss modeling of CPP-621 area and also grease pit S. of CPP-608 area. (Bob Secondo, DOE-ID, indicated that M-K in Boise had done some computer modeling and work at CPP which would be helpful in determining extent of migration of materials from spills nPar the CPP-621 area.) M-K could offer no information but rade a sales pitch for a contract to assist in studies or work in the area.

09/19/86 Meeting conducted with Ken Hein, Wendell Random, Jeff Ruffner, Tony Matule, George Buker and Joan Poland to discuss characterization cost and time to characterize area to be used for Secondary Containment Project. Conference call placed to Jerry Lyle DOE-ID to discuss the characterization. See attached for alternatives to the $138K sanpling plan as suggestPd by Jerry Lyle. DOE-ID indicated they would contact WINCO when they have decided on the option WINCO should use. DOE asked that we explore a fla1ed down sampling program which would give indications of the ragnitude of cleanup which would be required or be used to determine if more characterization would be required.

09/22/86 UURI was requested to submit a cost estimate for a scaled down sampling activity.

10/08/86 UURI sutmittPd a cost estimate of $18K for small scale sampling (grab samples). o o Page 2 - I CD 1\.) 10/86 Jerry Lyle (DOE) indicated WTNCO should take some grab samples for acid analysis since the soil may have had a neutralizing effect. Jerry recommended a review of the history of bulk Chemical receipts for indications of hazardous constituents in the Chemicals.

10/86 Bulk chemical specifications were reviewed on a preliminary baqis. Indications are that heavy metals are not present.

11/86 Samples which are available from a previous grab sample program are being analyzed. This will not give conclusive results for characterization but will give preliminary indication to plan future work. Until more information is available it is thought that the project excavation could proceed with concurrent sampling. This mode could place the project in jeopardy if the samples indicate hazardous materials which cannot be cleaned up concurrent with construction. Construction personnel concerns with excavating of hazardous materials or in low PH soil are possible and could cause project delays. this situation exists whernever any excavation is undertaken but is more likely at a known spill site.

The following procedures need to be followed for the removal of the soil contaminated with Nitric Acid at CPP-621.

1. All contaminated soil will be placed into poly lined drums (available at CFA) for disposal. (30 gallon size recommended but not required.)

2. Areas where the acid pooled, allowing for the absorption of the acid into the ground, will require the removal of the majority of contaminated soil. This involves primarily the area along the concrete wall south of CS151 (the horizontal nitric acid tank).

a) The amount of soil to be removed will be dependent on the amount of absorption that took place. Contact Rochelle Honkus at 6-3206 or Bob Marcinko at 6-3590 for any questions.

b) The amount of soil to be removed from the area south of CS151 will need to extend to the base of the recently poured concrete retaining wall.

c) The area to the south east of CS151 along the north/south running trench presently under construction needs to be cleaned up initially. This will include the removal and disposal of the polyethlene sheeting, the wood forms and the surface layer of soil (approximately 1-2 inches of soil).

3. Following the clean up procedures, the area shall be thoroughly flushed with water. Contact with Rochelle Honkus or Bob Marcinko shall be made prior to the wash down procedure to ensure sufficient soil has been removed.

4. Personnel exposed to the contaminated soil (those removing it and filling the drums) shall wear as a minimum the following personnel protective equipment: acid boots, disposable acid clothing, acid gloves, full face respirators with combination cartridges.

5. All drums prior to being sealed will need to be checked for its acid concentration. This will be done with pH paper under the direction of Rochelle Honkus or Bob Marcinko. Drums that contain soil that is still acidic will need to have a layer of soda ash added to the surface.

6. Wood forms and any other materials that are suspect of acid contamination shall be disposed of in non compactable waste containers.

ii 1.0 INTRODUCTION

This report presents the results of a preliminary characterization of potential soil contamination at the Hydrofluoric Acid

Storage Tank Area (CPP-727) at the Idaho Chemical Processing

Plant (CPP) complex (Figs. 1 and 2). The plant, managed by the

Westinghouse Idaho Nuclear Company, Inc. (WINCO), is located approximately 50 miles west of Idaho Falls, Idaho. The project was undertaken to identify the nature and levels of hazardous constituents that may be present in the soils at this storage facility. The characterization is based on chemical analyses of soil samples collected by personnel and associates of the

University of Utah Research Institute (UURI) on November 16,

1987.

2.0 SITE DESCRIPTION

The Hydrofluoric Acid Storage Tank Area is a concrete lined

excavation approximately 16 feet by 28 feet by 12 feet deep

located at the southern end of the Chemical Storage Area (Fig.

2). The floor of the excavation contains two concrete footings

that are each approximately 7 feet 10 inches wide by 10 feet

long. The remaining portions of the base of the excavation are

covered with gravel-rich soil. Prior to sampling, the excavation

was filled with limestone to neutralize any acid that may have

spilled during the operation of this facility. A drain located

on the north wall presently discharges steam condensate into the

excavation. The drain is enclosed within a metal cage that

1 extends to within several inches of the base of the excavation.

The soil beneath the drain has collapsed into a small pit

approximately 1 foot across.

No detailed site history documenting the extent of chemical

discharges to the ground at the Hydrofluoric Acid Storage Tank

aaArea is available. However previous sampling indicated that

the fluoride contents of the soils at this storage facility were

above background levels (refer to UURI Final Report: Chemical

Storage and Zirconium Feed Tank Storage Areas, Idaho Chemical

Processing Plant: Sept. 1987).

3.0 SITE GEOLOGY

The sampling sites are underlain by sand, gravel and clay-

rich sediments which unconformably overlie basalt. The sediments

in nearby excavations on the CPP site are approximately 40 feet

thick. The thickness of the basalt has not been established. A

three foot thick clay horizon above the basalt was previously

sampled in one of the excavations and mineralogically analyzed at

UURI. X-ray diffraction analysis of this sample indicates that

it consists of approximately 25% quartz, 10', plagioclase, 5%

potassium feldspar, 15% smectite, 5% illite, 1% chlorite, 1%

kaolinite, and 36% glass.

4.0 SAMPLING PROCEDURE

The soil sampling techniques and procedures employed during

the project are described in the accompanying Quality Assurance

2 o o cn

Sampling Plan. The locations of the soil samples collected from iC

the Hydrofluoric Acid Storage Tank Area are shown in Figure 3.

5.0 ANALYTICAL PROCEDURES AND RESULTS

The samples collected during this study were analyzed for

soil pH, fluoride (F; water extractable) and heavy metals (total

metal analysis) which may have been discharged to the soils or

leached by the acids. These metals include arsenic (As), barium

(Ba), chromium (Cr), lead (Pb), mercury (fig), selenium (Se), and

silver (Ag). Soil moisture was also determined in order to

relate the analytic concentrations, determined on the basis of

dry weight, to in-situ weight concentrations.

5.1 Analytical Results

Analysis of the soils was performed by the University of

Utah Research Institute (UURI) located in Research Park at 391

Chipeta Way, Suite A, Salt Lake City, Utah. This laboratory is

certified in the State of Utah by the State Health Laboratory,

Bureau of Laboratory Improvement for the recuired metal analyses.

Utah is a "Primacy" state in which EPA RCRA programs are managed

at the state level by authorized state agencies. The Chain of

Custody (COC) form for samples submitted to this laboratory are

contained in Appendix 1.

The analytical results are presented in Table 1. Note that

values for moisture are expressed as percentage levels (%), Hg

and Se are expressed in parts per billion (ppb ), and the

3 o o CD ka remaining elements are given in parts per million (ppm). A11 analyses are reported on a weight per dry weight basis. The EPA- approved methods utilized for these analyses are described in the accompanying Quality Assurance Sampling Plan.

6.0 DATA QUALITY

The precision and accuracy of the analyses were determined from a statistical evaluation of field and laboratory quality control samples. Precision data were obtained from duplicate analyses of field and laboratory quality control samples.

Accuracy data were obtained from analyses of standard reference materials, spiked field samples, and laboratory standard samples.

EPA has nominally established control limits for precision and accuracy as plus or minus three standard deviations about the mean. Analytical data produced while quality control data

remains within this limitation meet the EPA-recommended 95%

Confidence Limit for data acceptability. Quality assurance data for project analyses are contained in Appendix 2 and summarized

in Table 2. These data indicate that the analyses of project samples fall within acceptable quality assurance limits.

Soil samples are heterogeneous and thus present inherent

analytical problems. Often very small particles of a particular

contaminant are not uniformly present throughout the sample

causing anomalies in the data which must be verified through

additional analyses. The UURI Earth Sciences Laboratory

4 performed multiple analyses and a thorough quality assurance evaluation in order to validate the precision and accuracy of its reported data.

Two of the field samples were collected in duplicate to assess the heterogeneity of the soils. Chemical analyses of the field duplicates are presented in Table 3. The duplicate samples were composited in a stainless steel bucket and split into two plastic containers at the time of collection.

7.0 EVALUATION OF RESULTS

The results of the sample analyses have been statistically compared to the concentrations found in previously collected background samples (Tables 4) to determine the distribution of anomalous values. Concentrations exceeding a value equal to the background mean + 2 standard deviations are underlined in Table

1. For comparison the range of metal contents typically found in soils over volcanic rocks is shown in Table 5.

The data show that all of the soil samples collected from the Hydrofluoric Acid Storage Tank Area are characterized by anomalous F contents. In addition, anomalous concentrations of

As, Ba, Cr, Pb, and Se occur in the soils sampled below the drain. The elevated concentrations of these metals are

consistent with the low pH of sample 8. Elevated concentrations

of As (samples 1,3,4, and 5), Ba (samples 3 and 5), Cr (samples

1, 3, 4, and 5), Pb (samples 1, 4, and 5) and Hg (sample 2) in

other samples in contrast, do not appear systematic and are

5 within the range of values typical of soils overlying volcanic

terrains.

~~4.0 SITE DESCRIPTION~~

~~The Hydrofluoric Acid Storage Tank Area is a concrete lined excavation approximately 16 feet by 28 feet by 12 feet deep. The~~

~~base of the excavation contains two concrete footings that are each approximately 7 feet 10 inches wide by 10 feet long.~~

~~Otherwise, the base of the excavation is unlined. The excavation~~

~~was filled with limestone to neutralize any acid that may have~~

~~spilled during operation of the facility. A drain located on the~~

~~north wall discharges steam condensate to the base of the pit.~~

~~5.0 SAMPLING RATIONALE~~

~~Surface sampling (0-4 inches) will be conc__:ted to~~

~~positively identify areas potentially impacted by the past~~

~~2 CD CD Cn CD handling practices associated with the chemicals stored in this area.~~

~~Subsurface soil samples will be collected 24 inches below each surface sampling site to assess the potential extent of downward migration.~~

A11 pertinent data, observations, and unusual conditions will be recorded in the field log book (see Section 6.7). A11 rationale for on-site decisions and implementation of action deviating from this sampling plan will be documented.

~~Additional'samples will be collected from any soils located in the sampling area that visually appear to be contaminated as indicated by dark stains, discoloration, odors, etc.~~

~~6.0 SAMPLING PROCEDURES~~

~~6.1 Soil Sampling~~

~~Throughout the sampling area, soil sampling will be~~

~~conducted at sites having the highest potential to exhibit~~

~~contamination. The proposed sampling locations are shown on~~

~~Figure 3.~~

~~A11 soil samples will be collected utilizing stainless steel~~

~~hand tools which have been decontaminated in accordance with~~

~~EPA-recommended procedures prior to the collection of each~~

~~sample. Augering to reach the subsurface soil sampling depth of~~

~~24 inches will be accomplished using a stainless steel hand~~

~~auger. If the hand auger is also to be used for sample~~

3 collection, it will again be decontaminatc:. prior c_ sample collection. The soil will be placed in a decontaminated stainless steel bucket until sufficient material has been collected from each sampling horizon. The soil will then be gently mIxed with a stainless steel spoon to homogenize the sample before being placed in an appropriate sampling container.

~~The sample container will then be properly labeled and prepared for transportation to the laboratory.~~

~~6.2 Sampling Equipment Decontamination~~

An area will be established at the site for the decontamination of a11 sampling equipment and protective clothing that may come in contact with hazardous ccnstituents. The decontamination area will be equipped with the necessary reagents, non-leaking containers, brushes and other appropriate equipment. Decontamination will involve (in order):

~~1. scrubbing with culinary water,~~

~~2. culinary water rinse,~~

~~3. acid rinse,~~

~~4. distilled water rinse,~~

~~Hand tools employed for sampling will be decontaminated~~

~~between each use and after sampling.~~

~~Protective clothing will be decontaminated, if required and~~

~~possible, or iisposed of along with the residues, solutions and~~

~~materials resulting from decontamination operations.~~

~~4 6.3 Sample Containers~~

~~Soil samples for inorganic analysis will be placed in~~

~~chemically clean, one pint, wide-mouth, plastic containers. A11~~

~~sample containers will be prepared by the laboratory for sampling~~

~~in accordance with EPA-approved protocols for the analytical~~

~~methods listed in Attachment 1.~~

~~6.4 Sample Container Labels and Seals~~

~~A11 sample containers will be sealed at the time of~~

~~collection with a non-tearable seal which bears the sampler's~~

~~name, date, and sample number. The seal shall be placed over the~~

~~lid and threaded ring to ensure that the sample has not been~~

~~tampered with prior to delivery to the laboratory.~~

~~A11 sample containers shall be labeled at the time of~~

~~collection with indelible ink pens. Sample labels will contain~~

~~the following information:~~

~~-Site number or project code~~

~~-Sample description~~

~~-Date of collection~~

~~-Time of collection~~

~~-Sample number~~

~~-Sample collector(s)~~

~~-Requested analyses~~

~~6.5 Sample Handling and Transport~~

~~5 After sealing and labeling, sample containers will immediately be placed in a cooler, and cooled to four degrees~~

~~Centigrade. The samples will be kept out of direct sunlight.~~

~~The cooler shall be suitable for vehicular transportation to the laboratory.~~

~~6.6 Field Quality Assurance/Quality Control Procedures~~

~~A blank sample will be taken in the field and handled along with the field samples and analyzed to assess cross contamination due to sample Ilindling practices.~~

~~A duplicate field sample will be collected and analyzed for each set of 20 or fewer samples to assess sampling, sample handling, and laboratory analytical performance.~~

~~METHOD 3050~~

~~ACID DIGESTION OF SLUDGES~~

~~1.0 Scope and Application~~

1.1 Method 3050 is an acid digestion procedure used ta prepare sludge- type and soil samples for analysis by flame or furnace atomic absorption spectroscopy (AAS) or by inductively coupled argon plasma spectroscopy (ICP). Samples prepared by Method 3050 may be analyzed by AAS or 1CP for the following metals:

~~Antimony Lead Arsenic Nickel Barium Selenium Beryllium Silver Cadmium Thallium Chromium Zinc Copper~~

1.2 Method 3050 may also be applicable to the analysis of other metals in sludge-type samples. However, prior to using this method for other metals, it must be evaluated using the specific metal and matrix.

~~2.0 Summary of Method~~

2.1 A dried and pulverized sample is digested in nitric acid and hydrogen peroxide. The digestate is'then refluxed with either nitric acid or hydrochloric acid. Hydrochloric acid is used as the final reflux acid for the furnace analysis of Sb or the flame analysis of Sb, Ba, 8e, Cd, Cr, Cu, Pb, Ni, and Zn. Nitric acid is employed as the final reflux acid for the furnace analysis of As, Ba, Be, Cd, Cr, Cu, Pb, Ni, Se, Ag, 71, and Zn or the flame analysis of Ag and Tl.

~~3.0 Interferences~~

3.1 Sludge samples can contain diverse matrix types, each of which may present its own analytical challenge. Spiked samples and any relevant standard reference material should be processed to aid in determining whether Method 30S0 is applicable to a given waste. Nondestructive techniques such as neutron activation analysis may also be helpful in evaluating the applicability of this digestion method.

~~4.2 Watch glasses.~~

~~A 'OA 4.3 Drying ovens that can be maintained at 30' C.~~

~~4.4 Thermometer that covers range of 0' to 200' C.~~

~~4.5 Whatman No. 42 filter paper or equivalent.~~

~~5.0 Reagents~~

~~5.1 ASTM Type II water (ASTM 01193): Water should be monitored for impurities.~~

~~5.2 Concentrated nitric acid: Acid should be analyzed to determine level of impurities. If impurities are detected, all analyses should be blank corrected.~~

~~5.3 Concentrated hydrochloric acid: Acid should be analyzed to determine level of impurities. If impurities are detected, all analyses should be blank corrected.~~

~~5.4 Hydrogen peroxide (307): Oxidant should be analyzed to determine level of impurities. If impurities are detected, all analyses should be blank corrected.~~

~~6.0 Sample Collection, Preservation, and Handling~~

~~6.1 All samples must have been collected using a sampling plan that addresses the considerations discussed in Section One of this manual.~~

~~6.2 A 1 sample containers must be prewashed with detergents, acids, and distilled deionized water. Plastic and glass containers are both suitable.~~

~~6.3 Nonaqueous samples shall be refrigerated when possible, and analyzed as soon as possible.~~

~~7.0 Procedure~~

~~7.1 Weigh and transfer to a 125-ml conical Phillips' beaker a 1.0-9 portion of sample which has been dried at 60' C, pulverized, and thoroughly mixed.~~

7.2 Add 10 ml of 1:1 nitric acid (HNO3), mix the slurry, and cover with a watch glass. Heat the sample at 95' C and reflux for 10 min. Allow the sample to cool, add 5 ml of conc. HNO3, replace the watch glass, and reflux for 30 min. Do not allow the volume to be reduced to less than 5 ml while maintaining a covering of solution over the bottom of the beaker.

~~Revised 4/84 APPENDIX 1.1 Cont. o o~~

CD 7.3 After the second reflux step has been completed and the sample has cooled, add 2 ml of Type 11 water and 3 ml of 30% hydrogen peroxide (H202). Return the beaker to the hot plate for warming to start the peroxide reaction. Care must be taken to ensure that losses do not occur due to excessively vigorous effervescence. Heat until effervescence subsides, and cool the beaker.

7.4 Continue to add 30% H202 in 1-ml aliquots with warming until the effervescence is minimal or until the general sample appearance is unchanged. (NOTE: Do not add more than a total of 10 ml 30% H202.)

7.5 If the sample is being prepared for the furnace analysis of Ag and Sb or direct aspiration analysis of Ag, Sb, Ba, Be, Cd, Cr, Cu, Pb, Ni, Tl, and Zn, add 5 ml of 1:1 HCI and 10 ml of Type II water, return the covered beaker to the hot plate, and heat for an additional 10 min. After cooling, filter through uhatman No. 42 filter paper (or equivalent) and dilute to 100 ml with Type II water (or centrifuge the sample). The diluted sample has an approximate acid concentration of 2.51 (v/v) HC1 and 0.5% (v/v) HNO3 and is now ready for analysis.

7.6 If the sample is being prepared for the furnace analysis of As, Ba, Be, Cd, Cr, Cu, Pb, Ni, Se, T1, and Zn, continue heating the acid-peroxide digestate until the volume has been reduted to approximately 2 ml, add 10 ml Type II water, and warm the mixture. After cooling, filter through datman No. 42 filter paper (or equivalent) and dilute to 100 ml with Type 11 water (or centrifuge the sample). The diluted digestate solution contains approximately 2% (v/v) HNO3. For analysis, withdraw aliquots of appropriate volume, add any required reagent or matrix modifier, and analyze by method of standard additions.

~~8.0 Quality Control~~

8.1 For each group of samples processed, procedural blanks (Type II water and reagents) should be carried throughout the entire sample-preparation and analytical process. These blanks will be useful in determining if samples are being contaminated.

~~8.2 Duplicate samples should be processed on a routine basis. Duplicate samples will be used to determine precision. The sample load will dictate the frequency, but 111% is recommended.~~

8.3 Spiked samples or standard reference materials should be employed to determine accuracy. A spiked sample should be included with each group of samples processed and whenever a new sample matrix is being analyzed.

~~8.4 The concentration of all calibration standards should be verified - - inst a quality control check sample obtained from an outside source.~~

~~8.5 The method of standard addition shall be used for the analysis of all EP extracts and whenever a new samP le matrix is being analyzed.~~

STORET NO. 01002 Inorganic, Dissolved 00095 Inorganic. Total 00997 Inorganic , Suspended 00996 l. Scope and Application 1.1 The silver diethyldithiocarbamate method determines inorganic arseni.: when present in concentrations at or above 10 ug/ I. The method is applicable to drinking water and most fresh and sa1ine waters in the absence of high concentrations of chromium, cobalt, copper, mercury, molybdcnum, nickel, and silvcr. Domestic and indui.:rial wastes may also be analyzed after digestion (see 3.3). 1.2 Difficulties may be encountered with certain industrial waste ma:trials containing volatile substances. High sulfur content of wastes may exceed remo‘ll capacity of the lead acetate scrubber. 2. Summary of Method 2.1 Arsenic in the sample is reduced to arsine, AsH j. in acid solutic in a hydrogen generator. The arsine is passed through a scrubber to remove sulfide an:: is absorbed in a solution of silver diethyldithiocarbamatc dissolved in pyridine. The rrd cornplex thus formed is measured in a spectrophotometer at 535 nrn. 3. Comments 3.1 In analyzing drinking water and most surface and ground waters, interferences are rarely encountered. Industrial waste samples should be spiked with a known acnount of arsenic to establish adequate recovery. 3.2 It is essential that the system be airtight during evolution of the arsine, t.r. avoid losses. 3.3 If concentration of the sample and/or oxidation of any organic matter is required, refer to Method 206.5.[Standard Methods, I4th Edition, Method 404B, p. 21z4, Procedure 4.a (1975)]. For sample handling and preservation, see part 4.1 of the Atz‘rnic Absorption Methods section of this manual. 3.31 Since nitric acid gives a negative interference in this test, use s lfuric acid as a preservative if only inorganic arscnic is being rneasured. 3.4 l-Ephedrine in chloroform has been found to be a suitable cc:vent for silver diethyldithiocarbarnate if the analyst finds the odor of pyridine obje-ztionable [Anal. Chem. 45, 1786(1973)]. 3.5 For quality control requirements and optional recommendations for use in drinking water analyses, see part 10 of the Atomic Absorption Methods section cf t his manual.

~~METHOD 7471~~

~~MERCURY TN SOLID OR SEMISOLID WASTE (MANUAL COLD-VAPOR TECHNIOUE)~~

~~1.0 Scope and Application~~

1.1 Method 7471 is approved for measuring total mercury (organic and inorganic) in soils, sediments, bottom deposits, and sludge-type materials. A11 samples must be subjected to an appropriate dissolution step prior to analysis.

~~2.0 Summary of Method~~

~~2.1 Prior to analysis the samples must be prepared according to the procedures discussed in this method.~~

2.2 Method 7471, a cold-vapor atomic absorption method, is based on the absorption of radiation at the 253.7-nm wavelength by mercury vapor. The mercury is reduced to the elemental state and aerated from solution in a closed system. The mercury vapor passes through a cell positioned in the light path of an atomic absorption spectrophotometer. Absorbance (peak height) is measured as a function of mercury concentration.

~~2.3 The typical detection limit for this method is 0.0002 mg/1.~~

~~3.0 Interferences~~

3.1 Potassium permanganate is added to eliminate possible interference from sulfide. Concentrations as high as 20 mg/1 of sulfide as sodium sulfide do not interfere with the recovery of added inorganic mercury from Type II water.

~~3.2 Copper has also been reported to interfere; however, copper concentrations as high as 10 mg/1 had no effect on recovery of mercury from spiked samples.~~

3.3 Seawaters, brines, and industrial effluents high in chlorides require additional permanganate (as much as 25 ml) since, during the oxidation step, chlorides are converted to free chlorine which also absorbs radiation 4E153 nm. Care must therefore be taken to ensure that free chlorine tlialitent before the mercury is reduced and swept into the cell. This may be accomplished by using an excess of hydroxylamine sulfate reagent. (25 ml). In addition, the dead air space in the BOO bottle must be purged before adding stannous sulfate. 8oth inorganic and organic mercury spikes have been quantitatively recovered from seawater using this technique.

~~3.4 Certain volatile organic materials that absorb at this wavelength may also cause interference. A preliminary run without reagents should determine if this type of interference is present.~~

~~APPENDIX 1.4 4.0 Apparatus and Materials~~

4.1 Atomic absorption spectrophotometer or equivalent: Any atomic absoption unit having an open sample presentation area in which to mount the absorption cell is suitable. Instrument settings recommended by the particular manufacturer should be followed. Instruments designed specifically for the measurement of mercury using the cold-vapor techntque are commercially available and may be substituted for the atomic absorptinn spectrophotometer.

~~4.2 Mercury hollow cathode lamp or electrodeless discharge lamp.~~

~~4.3 Recorder: Any multirange variable speed recorder that is compatible with the UV detection system is suitable.~~

4.4 Absorption cell: Standard spectrophotometer cells 10 cm long having quartz end windows may be used. Suitable cells may be constructed from plexiglass tubing, 1 in. 0.0. x 4.5 in. The ends are ground perpendicular to the longitudinal axis and quartz windows (1 in. diameter x 1/16 in. thickness) are cemented in place. The cell is strapped to a burner for suPport and aligned in the light beam by use of two 2-in. x 2-in. cards. One-in.-diameter holes are cut in the middle of each card. The cards are then placed over each end of the cell. The cell is then positioned and adjusted vertically and hor",zontally to give the maximum transmittance.

~~4.5 Air p.mp: 'Any peristaltic pump capable of delivering 1 liter 3ir/min may be used. A Masterflex pump with electronic speed control has been fou7d to be Satisfactory.~~

~~4.6 Flowmeter: Capable of me2,:uring an air flow of 1 liter/min.~~

~~4.7 Aeration tubing: A straight glass frit having a coarse porosity. Tygon tubing is used for passage of the mercury vapor from the sample bottle to the absorption cell and return.~~

4.8 Drying tube: 6-in. x 3/4-in.-diameter tube containing 20 g of magnesium perchlorate or a small reading lamp with 60-W bulb which may be used to prevent condensation of moisture inside the cell. The lamp should be positioned to shine on the absorption cell so that the air temperature in the cell is about 10. C above ambient.

~~4.9 The cold-vapor generator is assembled as shown in Figure 1.~~

~~4.10 The apparatus shown in Figure 1 is a closed system. An open system, where the mercury vapor is passed through the absorption cell only once, may be used instead of the closed system.~~

Therefore, a bypass has been included in the system to either vent the mercury vaper into an exhaust hood or pass the vapor through Some absorbing media, such as:

~~1. equal volumes of 0.1 M KMn04 and 10: H2SO4~~

~~2. 0.25; iodine in a 3% KI solution~~

~~A specially treated charcoal that will adsorb mercury vapor is also available from Barnebey and Cheney, E. 8th Ave. and N. Cassidy St., Columbus, Ohio 43219, Cat. #580-13 or #580-22.~~

~~5.0 Reagents~~

~~5.1 ASTM Type II wa - (ASTM 01193): Water should be monitored for impurities.~~

~~5.2 Aqua regia: Pre,:,a.-e immediately cefore use by carefully adding three volumes of conc. HCI to one volume of conc. HNO3.~~

~~5.3 Sulfuric acid, 0.5 N: Dilute 14.0 ml of conc. sulfuric acid to 1 liter.~~

5.4 Stannous sulfate: Add 25 g stannous sulfate to 250 ml of 0.5 N sulfuric acid. This mixture is a suspension and should te stirred continu- ously during use. A 10% solution of stannous chloride can be substituted for stannous sulfate.

5.5 Sodium chloride-hydroxylamine sulfate solution: Dissolve 12 g of sodium chloride and 12 g of hydroxylamine sulfate in Type 11 water and dilute to 100 ml. Hydroxylamine hydrochloride may be used in place of hydroxylamine sulfate.

~~5.6 Potassium permanganate, 5: solution ,w/v): Dissolve 5 g of potassium permanganate in 100 ml of Type 11 water.~~

~~5.7 Mercury stock solution: Dissolve 0.1354 g of mercuric chloride in 75 ml of distilled water. Add 10 ml of conc. nitric acid and adjust the volume to 100.0 ml (1.0 ml = 1.0 mg Hg).~~

5.8 Mercury working standard: Make successive dilutions of the stock mercury solution to obtain a working standard containing 0.1 ug/ml. This working standard and the dilution of the stock mercury solutions should be prepared fresh daily. Acidity of the working standard should be maintained at 0.15: nitric acid. This acid should be acded to the flask as needed before adding the aliquot. c METHOD 7741

~~SELENIUM (ATOMIC ABSORPTION, GASEOUS HYDRIDE)~~

~~1.0 Scope and Application~~

1.1 Method 7741 is an atomic absorption procedure which is approved for determining the concentration of selenium in wastes, mobility procedure extracts, soils, and groundwater, provided that the sample matrix does not contain high concentrations of chromium, copper, mercury, silver, cobalt or molybdenum. All samples must be subjected to an appropriate dissolution step prior to analysis. Spiked samples and relevant standard reference materials are employed to determine applicability of the method to a given waste.

~~2.0 Summary of Method~~

2.1 Samples are prepared according to the nitric/sulfuric acid digestion procedure described in this method. Next, the selenium in the digestate is reduced to the +4 form ustng tin chloride. The +4 selenium is then converted to a volatile hydride with hydrogen produced from a zinc/HC1 reaction.

2.2 The volatile hydride is swept into an argon-hydrogen flame located in the optical path of an atomic absorption spectrophotometer, and the resulting absorbance is proportional to the selenium concentration.

~~2.3 The typical detection limit for this method is 0.002 mg/1..~~

~~3.0 Interferences~~

~~3.1 High concentrations of chromium, cobalt, copper, mercury, molybdenun nickel, and silver can cause analytical interferences.~~

~~3.2 Traces of nitric acid left following the sample workup can result in analytical interferences. Nitric acid must be distilled off by heating the sample until fumes of S03 are observed.~~

~~3.3 Elemental selenium and many of its compounds are volatile and therefore certain samples may be subject to losses of selenium during sample preparation.~~

~~4.0 Apparatus and Materials~~

~~4.1 100-ml beaker.~~

~~4.2 Electric hot plate.~~

~~4.3 A commercially available zinc slurry hydride generator or a generator constructed from the following material (see Figure 1).~~

~~'nne.,m,"V 1 5.6 Potassiun iodide solution: Oissolve 20 g CI in 100 ml Type 11 ' water.~~

~~5.7 Stannous chloride solution: Oissolve 100 g SnCl2 in 100 ml of conc. HCI.~~

5.8 Selenium standard stock solution: 1000 mg/liter solution may be purchased, or prepared as follows. Oissolve 0.3453 g of selenious acid (assay 94.61 of H2Se03) in Type 11 water. Add to a 200-ml volumetric flask and bring to volume (I ml = 1 mg Se).

~~6.0 Sample Collection, Preservation. and Handling~~

~~6.1 A11 samples must have been collected using a sampling pian that addresses the considerations discussed in Section One of this manual.~~

~~6.2 All sample containers must be prewashed with detergents, acids, and Type 11 water. Plastic and glass containers are both suitable.~~

~~6.3 Special containers (e.g., containers used for volatile organic analysis) may have to be used if very volatile selenium compounds are to be analyzed.~~

~~6.4 Aqueous samples must be acidified to a pH of less than 2 with nitric acid.~~

~~6.5 Nonaqueous samples shall be refrigerated where possible, and analyzed as soon as possible.~~

~~7.0 Procedure~~

~~7.1 Sample preparation~~

7.1.1 To a 50 ml aliquot of digested sample (or in the case of EP extracts a 50-ml sample) add 10 ml conc. HNO3 and 12 ml of 18 N H2SO4. Evaporate the sample on a hot plate until white S03 fumes are observed (a volume of about 20 ml). Do not let it char. If it chars, stop the digestion, cool and add additional HNO3. Maintain an excess of HNO3 (evidence of brown fumes) and do not let the solution darken, because selenium may be reduced and lost. When the sample remains colorless or straw yellow during evolution of S03 fumes, the digestion is complete.

7.1.2 Cool the sample, add about 25 ml distilled deionized water and again evaporate to SO3 fumes just to expel oxides of nitrogen. Cool. Add 40 ml conc. HCI and bring to a volume of 100 ml with distilled deionized water.

~~1.5 Cont. ,evised 4/84 APPENDIX 7.2 Prepare working standards from the standard stock solutions. The following procedure provides standards in the optimum working range.~~

7.2.1 Pipet 1 ml stock solutlon into a 1-liter volumetric flask. Bring to volume with Type 11 water containing 1.5 ml conc. HNO3/liter. The concentration of thls solution is 1 mg Se/liter (1 ml = 1 pg Se).

7.2.2 Prepare six working standards by transferring 0, 0.5, 1.0, 1.5, 2.0 and 2.5 ml of the selenium stock standard (see Section S.8) into a 100-ml volumetric flasks. Bring to volume with diluent. The concentrations of these working standards are 0, S, 10, 15, 20 and 25 pg Se/liter.

~~7.3 Standard additions~~

7.3.1 Take the 15-, 20-, and 25-pg standards and transfer quantitatively 25 ml from each into separate 50-ml volumetric flasks. Add 10 ml of the prepared sample to each. Bring to volume with Type 11 water containing 1.5 ml HNO3/liter.

~~7.3.2 Add 10 ml of prepared sample to a 50-ml volumetric flask. Bring to volume with Type 11 water containing 1.5 ml H1103 per liter. This is the blank.~~

7.4 Follow the manufacturer's instructions for operating an argon- hydrogen flame. The argon-hydrogen flame is colorless so it may be useful to spirate a lowconcentration of sodium to ensure that ignition has occurred.

~~7.5 The 196.0-nm wavelength shall be used for the analysis of selenium.~~

7.6 Transfer a 25-ml portion of the digested sample or standard to the reaction vessel. Add 0.5 ml SnC12 solution. Allow at least 10 min for the metal to be reduced to its lowest oxidation state. Attach the reaction vessel to the special gas inlet-outlet glassware. Fill the medicine dropper with 1.50 ml zinc slurry that has been kept in suspension with the magnetic stirrer. Firmly insert the stopper containing the medicine dropper into the side neck of the reaction vessel. Squeeze the bulb to introduce the zinc slurry into the sample or standard solution. The metal hydride will produce a peak almost immediately. When the recorder pen returns partway to the base line, remove the reaction vessel.

~~7.7 Analyze. by the method of standard additions, all EP extracts, all samples analyzed as pert of a delisting petition, and all samples that suffer from matrix interferences.~~

~~7.8 Duplicates, spiked samples, and check standards should be routinely analyzed.~~

~~Method 340.2 (Potentiometric, Ion Selective Electrode)~~

~~STORET NO: Total 00951 Dissolved 00950~~

I. Scope and Application 1.1 This method is applicable to the measurement of fluoride in drinking, surface and saline waters, domestic and industrial wastes. 1.2 Concentration of fluoride from 0.1 up to 1000 mg/liter may be measured. 1.3 For Total or Total Dissolved Fluoride, the Bellack distillation is required for NPDE.S monitoring but is not required for SDWA monitoring. 2. Summary of Method 2.1 The fluoride is determined pot.:atiometrically using a fluoride electrode in conjunction with a standard single junction sleeve-type reference electrode and a pH meter having an expanded millivolt scale or a selective ion meter having a direct concentration scale for fluoridc. 2.2 The fluoride electrode consists of a lanthanum fluoride crystal across which a potential is developed by fluoride ions. The cell may be represented by Ag/Ag Cl, 0-(0.3), F(0.001) LaF/test solution/SCE/. 3. Interferences 3.1 Extremes of pH interfere; sample pH should be between 5 and 9. Polyvalent cations of Si'', Fe•' and Al" interfere by forming complexes with fluoride. The degree of interference depends upon the concentration of the complexing cations, the concentration of fluoride and the pH of the sample. The addition of a pH 5.0 buffer (described below) containing a strong chelating agent preferentially complexes aluminum (the most common interference), silicon and iron and eliminates the pH problem. 4. Sampling Handling and Preservation 4.1 No special requirements. 5. Apparatus 5.1 Electrometer(pH meter), with expanded mv scale, or a selective ion meter such as the Orion 400 Series. 5.2 Fluoride Ion Activity Electrode,such as Orion No.94-09'. 5.3 Reference electrode, single junction, sleeve-type, such as Orion No. 90-01, Beckman No. 40454, or Corning No. 476010. 5.4 Magnetic Mixer, Teflon-coated stirring bar.

APPENDIX 1. 6 340.2-1 6. Reagents 6.1 Buffer solution, pH 5.0-5.5: To approximately 500 ml of distilled water in a I liter beaker add 57 ml of glacial acctic acid, 58 g of sodium chloride and 2 g of CDTA'n. Stir to dissolve and cool to room temperature. Adjust pH of solution to between 5.0 and 5.5 with 5 N sodium hydroxide (about 150 ml will be required). Transfer solution to a 1 liter volumetric flask and dilute to the mark with distilled water. For work with brines, additional NaCI should be added to raise the chloride level to twice the highest expected level of chloride in the sample. 6.2 Sodium fluoride, stock solution: 1.0 ml = 0.1 mg F. Dissolve 0.2210 g of sodium fluoride in distilled water and dilute to l liter in a volumetric flask. Store in chemical-resistant glass or polyethylene. 6.3 Sodium fluoride, standard solution: 1.0 ml = 0.01 mg F. Dilute 100.0 ml of sodium fluoride stock solution (6.2) to 1000 ml with distilled water. 6.4 Sodium hydroxide, 5N: Dissolve 200 g sodium hydroxide in distilled water, cool and dilute to l liter. 7. Calibration 7.1 Prepare a series of standards using the fluoride standard solution (6.3) in the range of0 to 2.00 mg/1 by diluting appropriate volumes to 50.0 ml. The following series may be used:

~~Millimeters of Standard Concentration when Diluted (1.0 ml = 0.01 rng/F) to 50 ml, rng F/liter~~

~~0.00 0.00 1.00 0.20 2.00 0.40 3.00 0.60 4.00 0.80 5.00 1.00 6.00 1.20 8.00 1.60 10.00 2.00~~

7.2 Calibration of Electrometer: Proceed as described in (8.1). Using semilogarithmic graph paper, plot the concentration of fluoride in mg/liter on the log axis vs. the electrode potential developed in the standard on the linear axis, starting with the lowest conceranthoo at the bottom of the scale. Calibration of a selective ion meter: Follow the directiantofthe manufacturer for the operation of the instrument. 8. Procedure 8.1 Place 50.0 ml of sample or standard solution and 50.0 ml of buffer (See Note)in a 150 ml beaker. Place on a magnetic stirrer and mix at medium speed. Immerse the electrodes in the solution and observe the meter reading while mixing. The electrodes must remain in the solution for at least three minutes or until the reading has stabilized. At concentrations under 0.5 mg/liter F, it may require as long as five minutes to reach a stable meter reading; high concentrations stabilize more quickly. If a pH meter is used, record thc potential measurement for each unknown sample and conven the potential

340.2-2 APPENDIX 1.6 Cont. reading to the fluoride ion concentration of the unknown using the standard curve. If a selective ion meter is used, read the fluoride level in the unknown nple di -tly in mg/l on the fluoride scale. NOTE: For industrial waste samples, this amount of buffer may not be adequate. Analyst should check pH first. If highly basic( > 9), add 1 N HCI to adjust pH to 8.3. 9. Precision and Accuracy 9.1 A synthetic sample prepared by the Analytical Reference Service, PHS, containing 0.85 mg/1 fluoride and no interferences was analyzed by 111 analysts; a mean of 0.84 mg/1 with a standard deviation of t0.03 was obtained. 9.2 On the same study, a synthetic containing 0.75 mg./1 fluoride, 2.5 mg/1 polyphosphate and 300 mg/1 alkalinity, was analyzed by the same I 1 1 analysts; a rnean of0.75 mg/1 fluoride with a standard deviation of t0.036 was obtained.

On March 14, 1991, John Wozniewics, Golder Associates Inc., and Brenda Cole, Environmental Restoration, observed the Excavation of asphalt south of CPP-621 and adjacent to Solid Waste Management Unit (SWMU) CPP-45. We were asked to observe for any discolored soil and run detector tube tests for hydrofluoric acid. The detector tubes were specific to hydrofluoric acid. Their expiration date was April 1992 and their range was 0-25 ppm.

The soil did not appear to show any signs of contamination. The detector tube was placed within 1-2 inches above the soil and below the surface of the soil in 5-6 different locations. The results of the detector tube testing indicated that hydrofluoric acid was not present.

~~At this time, I see no reason why excavation work can not continue for your project.~~

~~If you have any questions or comments, please feel free to contact me at 526-8520.~~

~~Chemical Processing Plant (CPP complex; Fig. 1). The complex, managed by the Westinghouse Idaho Nuclear Company, Inc. (WINCO), is located approximately 50 miles west of Idaho Falls, Idaho.~~

~~The project was undertaken to identify the nature and levels of potential hazardous wastes that may have been spilled during the storage and transfer of chemicals at the Chemical Storage Areas.~~

The characterization is based on results from the chemical analysis of soil samples collected by personnel and associates of the University of Utah Research Institute (UURI) between April 13 and 16, 1987. In addition, analyses of drillcore collected by • WINCO personnel from the chemical storage area are given in this report. The analyses of these drillcore samples were performed according to EPA protocol and with approved methods. However, the drilling was not performed by UURI and UURI has no direct knowledge of the sampling procedures followed. Thus, drillcore data are presented for comparison only, and are not here represented aS being valid for submittal to EPA for regulatory

~~purposes.~~

~~2.0 SITE LOCATION~~

~~The Chemical Storage Area (Fig. 2) is approximately 130 feet~~

~~by 90 feet and encompasses the Chemical Storage Pump House o o~~

~~Cn (CPP-621), the Nitric Acid Storage Tank Area (CPP-719) and o adjacent sludge pit, the Aluminum Nitrate Storage Tank Area~~

~~(CPP-720), the Hydrofluoric Acid Storage Tank Area (CPP-727), the~~

~~Sulfuric Acid and Hydrochloric Acid Tank Area (CPP-759), and the chemical drain lines servicing these areas.~~

~~The Zirconium Feed Tank Storage Area (CPP-637) is located approximately 675 feet north-northwest of the main Chemical~~

~~Storage area. A 30 x 30 foot was sampled at this facility (Fig.~~

~~3).~~

~~3.0 SITE GEOLOGY~~

~~The sampling sites are underlain by sand, gravel and clay-~~

~~rich sediments which unconformably overlie basalt. The sediments~~

~~in nearby excavations on the CPP site are approximately 40 feet~~

~~thick. The thickness of the basalt has not been established. A~~

~~three foot thick clay horizon above the basalt was previously~~

~~sampled in one of the excavations and mineralogically analyzed at~~

~~UURI. X-ray diffraction analysis of this sample indicates that~~

~~it consists of approximately 25% quartz, 10% plagioclase, 5%~~

~~potassium feldspar, 15% smectite, 5% illite, 1% chlorite, 1%~~

~~kaolinite, and 36% glass.~~

~~4.0 SAMPLING PROCEDURE~~

~~The soil sampling techniques and procedures employed during~~

~~the project are described in the accompanying Quality~~

~~2 o o~~

~~Cn Assurance/Quality Control Sampling Plan (refer to Volume 1). -1 Soil sample locations are shown in Figs. 1 through 3.~~

Three background soil samples were collected from areas outside the CPP complex (Fig. 1) utilizing the same sampling techniques. Background Site 1 (samples 860258 and 860259) was located in an area approximately 300 feet southeast of the

~~wastewater treatment facility and 35 feet east of the dirt road.~~

~~Background Site 2 (samples 860260 and 860261) was located in an area approximately 730 feet east-northeast of the coal-fired steam plant. Background Site 3 (samples 860264 and 860265) was~~

~~located in an area west of the western CPP access road and 180~~

~~feet away from a white shack. Precise locations of these~~

~~background sites have been determined by WINCO personnel and are~~

~~available from them.~~

~~5.0 ANALYTICAL PROCEDURES AND RESULTS~~

~~Aluminum nitrate and various acids including nitric,~~

~~sulfuric, hydrofluoric, and hydrochloric acid, have been stored~~

~~at the Chemical Storage Area. The available data indicates that~~

~~aluminum nitrate and nitric acid have been discharged to the soil~~

~~through french drains as a result of spills and leaks. The~~

~~largest reported spill occurred in 1982, and involved~~

~~approximately 1200 gallons of nitric acid. The extent of leaks~~

~~or spills involving other chemicals at the Chemical Storage Area~~

~~is not known.~~

~~3 o o~~

~~Cn No detailed site history documenting the extent of chemical o~~

~~discharges to the ground in the Zirconium Feed Tank Storage Area~~

~~is available. However, 450 gallons of zirconium feed is reported~~

~~to have spilled from one of the tanks in November, 1978.~~

~~Based on this information, the samples collected during~~

~~this study were analyzed for soil pH, nitrate (NO3 -N), aluminum~~

~~(A1), and heavy metals which may have been discharged to the~~

~~soils or leached by the acids. These metals are barium (Ba),~~

~~chromium (Cr), lead (Pb), silver (Ag), zircon (Zr), mercury (Hg),~~

~~arsenic (As), and selenium (Se). Soil moisture was also~~

~~determined in order to relate the analytic concentrations,~~

~~determined on the basis of dry weight, to in-situ weight~~

~~concentrations.~~

~~5.1 Analytical Results~~

~~Analysis of the soils was performed by the University of~~

~~Utah Research Institute (UURI) located in Research Park at 391~~

~~Chipeta Way, Suite A, Salt Lake City, Utah. This laboratory is~~

~~certified in the State of Utah by the State Health Laboratory,~~

~~Bureau of Laboratory Improvement for the required metal analyses.~~

~~Utah is a "Primacy" state in which EPA RCRA programs are managed~~

~~at the state level by authorized state agencies. Chain of~~

~~Custody (COC) forms for samples submitted to this laboratory are~~

~~contained in Appendix 1.~~

~~The analytical results are presented in Table 1 and the~~

~~locations of the samples are shown in Figs. 2 and 3. Note that~~

4 o o values for moisture, Al and Ba are expressed as percentage levels Cn o ,d (%), Hg and Se are expressed in parts per billion (ppb), and the remaining elements are given in parts per million (ppm). A11 analyses are total constituent analyses and are reported on a weight per dry weight basis. The EPA-approved methods utilized for these analyses are listed in "Test Methods for Evaluating

~~Solid Wastes (SW-846), Second Edition Revised, EPA, April 1984~~

~~(refer to Vol. 1, Appendix 1).~~

~~6.0 DATA QUALITY~~

~~The accuracy and precision of the analyses were determined from a statistical evaluation of the quality control samples.~~

~~are nominally established by the EPA to be equal to the mean + 3 standard deviations. Quality control data for the analyses are~~

~~contained in Appendix 2. These data indicate that the analyses~~

~~fall within acceptable limits. A summary of the precision and~~

~~accuracy data for the analyses is presented in Table 2.~~

~~Soil samples are heterogeneous and thus present inherent~~

~~analytical problems. Often very small particles of a particular~~

~~contaminant may not be present uniformly throughout the sample~~

~~causing anomalies in data which must be verified through addi-~~

~~5 o o tional analysis. The UURI Laboratory performed many additional o analyses to confirm the accuracy of all data.~~

~~7.0 EVALUATION OF RESULTS~~

~~The results of the sample analyses have been statistically~~

~~compared to the concentrations found in the background samples~~

~~(Tables 3) to determine the distribution of anomalous values. o cr Concentrations exceeding a value equal to the background mean + 2~~

~~standard deviations are underlined in Table 1. For comparison~~

~~the range of metal contents typically found in soils over~~

~~volcanic rocks is shown in Table 4.~~

~~The data show that anomalous metal, F, and NO3 -N concentra-~~

~~tions in soil from the Chemical Storage Facility are found in~~

~~areas where the discharge of acids or aluminum nitrate is known~~

~~to have occurred. These areas include the french drains,~~

~~chemical trench, hydrofluoric acid containment area and the~~

~~sludge pit. In addition, the majority of the core samples~~

~~submitted for analysis are also enriched in NO3 -N. The highest~~

~~concentrations of NO3 -N in the core samples occur in the deepest~~

~~samples, suggesting that the nitrate has been leached downward.~~

~~Soil samples collected from the Zirconium Feed Tank Storage~~

~~Area contain anomalous concentrations of Zr (860242, 860243,~~

~~860246, 820251 to 860254, 860257), A1 (860251), Cr (860242,~~

~~860243, 860251) and As (860257).~~

~~This plan contains the quality assurance guidelines for sampling, analysis, and data reporting activities for the preliminary characterization of soil contamination at the~~

~~Chemical Storage and Zirconium Feed Tank Storage Areas (Figs. 1-~~

~~3) of the Westinghouse Idaho Nuclear Company, Inc. (WINCO).~~

~~2.0 OBJECTIVES AND SCOPE OF THE PROJECT~~

~~This soil sampling and analysis project will be conducted by personnel of the University of Utah Research Institute (UURI) to characterize the upper two feet of soils beneath the Chemical~~

~~Storage and Zirconium Feed Tank Storage Areas. This project plan is designed to identify the nature and quantity of hazardous constituents that may be present in the soils as a result of past~~

~~Operations.~~

~~3.0 PROJECT ORGANIZATION AND RESPONSIBILITY~~

~~The project organization is shown in Figure 4. The~~

~~Principal-In-Charge will have overall responsibility for:~~

~~1. direction of the project;~~

~~2. communication with local, state, and federal regulatory~~

~~agencies and;~~

~~3. data and project reporting.~~

~~The Project Manager will be responsible for:~~

~~1. the preparation of project plans;~~

~~1 0 o Fy c: o 2. execution of all activities in accordance with project cr) plans and;~~

~~3. communication with the Principal-In-Charge.~~

~~collection.~~

~~4.0 SITE DESCRIPTION~~

~~The Chemical Storage Area (Fig. 2) is approximately 130 feet by 90 feet and encompasses the Chemical Storage Pump House~~

~~(CPP-621), the Nitric Acid Storage Tank Area (CPP-719) and adjacent sludge pit, the Aluminum Nitrate Storage Tank Area~~

~~(CPP-720), the Hydrofluoric Acid Storage Tank Area (CPP-727), the~~

~~Sulfuric Acid and Hydrochloric Acid Tank Area (CPP-759), and the chemical drain lines servicing these areas.~~

~~An additional 30 by 30 foot sampling area (Fig. 3), containing the Zirconium Feed Tank (CPP-637), located~~

~~2 c c~~

~~Cr) c approximately 675 feet north-northwest of the main Chemical CD~~

~~Storage area, will also be sampled.~~

~~The Chemical Storage Area has been utilized since the late~~

~~1970's to store various acids and aluminum nitrate in large metal and fiberglass tanks encircled by earth berms. In March 1982, a nitric acid spill of approximately 1200 gallons occurred in the~~

Chemical Storage Area at CPP-719. The acid was neutralized utilizing soda ash and soils known to be contaminated were excavated for disposal. Zirconium compounds have been stored at the Zirconium Feed Tank Storage Area in free-standing tanks. In

~~November, 1978, 450 gallons of zirconium feed spilled from one of the tanks.~~

~~5.0 SAMPLING RATIONALE~~

~~Surface sampling (0-4 inches) will be conducted to positively identify areas potentially impacted by the past handling practices associated with the chemicals stored in this area.~~

~~Subsurface soil samples will be collected 24 inches below each surface sampling site to assess the potential extent of downward migration.~~

~~3 Background subsurface soil samples, geologically identical to soils in the sampling area, will be collected and analyzed.~~

Background samples will be taken in areas that are far enough away from the sampling site to preclude the effects of contamination. These samples will be analyzed to establish background levels of inorganic constituents in soils on the CPP facility.

~~Additional samples will be collected from any soils located in the sampling area that visually appear to be contaminated as indicated by dark stains, discoloration, odors, etc.~~

~~METHOD 3050~~

~~ACID DIGESTION OF SLUDGES~~

~~1.0 Scope and Application~~

1.1 Method 3050 is an acid digestion procedure used to prepare sludge- type and soil samples for analysis by flame or furnace atomic absorption spectroscopy (AAS) or by inductively coupled argon plasma spectroscopy (ICP). Samples prepared by Method 3050 may be analyzed by AAS or ICP for the following metals:

~~Antimony Lead Arsenic Nickel Bari um Selenium Beryllium Silver Cadmi um Thallium Chromium Zinc Copper~~

~~2.0 Summary of Method~~

2.1 A dried and pulverized sample is digested in nitric acid and hydrogen peroxide. The digestate is'then refluxed with either nitric acid or hydrochloric acid. Hydrochloric acid is used as the final reflux acid for the furnace analysis of Sb or the flame analysis of Sb, Ba, Be, Cd, Cr, Cu, Pb, Ni, and Zn. Nitric acid is employed as the final reflux acid for the furnace analysis of As, Ba, Be, Cd, Cr, Cu, Pb, Ni, Se, Ag, T1, and Zn or the flame analysis of Ag and Tl.

~~3.0 Interferences~~

3.1 Sludge .samples can contain diverse matrix types, each of which may present its own analytical challenge. Spiked samples and any relevant standard reference material should be processed to aid in determining whether Method 30S0 is applicable to a given waste. Nondestructive techniques such as neutron activation analysis may also be helpful in evaluating the applicability of this digestion method.

7.5 If the sample is being prepared for the furnace analysis of Ag and Sb or direct aspiration analysis of Ag, Sb, Ba, Be, Cd, Cr, Cu, Pb, Ni, T1, and Zn, add 5 ml of 1:1 HC1 and 10 ml of Type 11 water, return the covered beaker to the hot plate, and heat for an additional 10 min. After cooling, filter through Whatman No. 42 filter paper (or equivalent) and dilute to 100 ml with Type 11 water (or centrifuge the sample). The diluted sample has an approximate acid concentration of 2.5% (v/v) HC1 and 0.5% (v/v) HNO3 and is now ready for analysis.

7.6 If the sample is being prepared for the furnace analysis of As, Ba, Be, Cd, Cr, Cu, Pb, Ni, Se, 71, and Zn, continue heating the acid-peroxide digestate until the volume has been reduced to approximately 2 ml, add 10 ml nf Type 11 water, and warm the mixture. After cooling, filter through Whatman No. 42 filter paper (or equivalent) and dilute to 100 ml with Type Il water (or centrifuge the sample). The diluted digestate solution contains Approximately 2% (v/v) HNO3. For analysis, withdraw aliquots of appropriate lume, add any required reagent or matrix modifier, and analyze by method of _andard additions.

~~8.0 Quality Control~~

8.1 For each group of samples processed, procedural blanks (Type II -eater and reagents) should be carried throughout the entire sample-preparation and analytical process. These blanks will be useful in determining if Lamples are being contaminated.

~~8.2 Duplicate samples should be processed on a routine basis. Duplicate :amples will be used to determine precision. The sample load will dictate :he frequency, but 10% is recommended.~~

8.3 Spiked samples or standard reference materials should be employed to determine accuracy. A spiked sample should be included with each group of :amples processed and whenever a new sample matrix is being analyzed.

~~8.4 The concentration of all calibration standards should be verified mainst a quality control check sample obtained from an outside source.~~

~~8.5 The method of standard addition shall be used for the analysis all EP extracts and whenever a new sample matrix is being analyzed.~~

Scope and Application 1.1 The silver diethyldithiocarbamate method determines inorganic arseni: when present in concentrations at or above 10 ug/1. The method is applicable to drinkinz water and most fresh and saline waters in the absence of high concentrations of C:.Tomium,- cobak, copper, mercury, molybdenum, nickel, and silver. Domestic and indus:rial wastes may also be analyzed after digestion (see 3.3). 1.2 Difficulties may be encountered with certain industrial waste mat:Hats containing volatile substances. High sulfur content of wastes may exceed remoN al capacity of the lead acetate scrubber. Summary of Method 2.1 Arsenic in the sample is reduced to arsine, AsE13, in acid solutic7. in a hydrogen generator. The arsine is passed through a scrubber to remove sulfide ar.:.! is absorbed in a solution of silver diethyldithiocarbamate dissolved in pyridine. The :-.td cornplex thus formed is measured in a spectrophotorneter at 535 nm. Comments 3.1 In analyzing drinking water and most surface and ground waters, intern:- rences are rarely encountered. Industrial waste samples should be spiked with a known ccriount of arsenic to establish adequate recovery. 3.2 It is essential that the system be airtight during evolution of the arsine, lc avoid losses. 3.3 If concentration of the sample and/or oxidation of any organic matter Es required, refer to Method 206.5.[Standard Methods, 14th Edition, Method 404B, p. 2.1'4, Procedure 4.a (1975)]. For sample handling and preservation, see part 4.1 of the At..Nmic Absorption Methods section of this manual. 3.3.1 Since nitric acid gives a negative interference -`in this test, use silfuric acid as a preservative if only inorganic arsenic is being measured. 3.4 1-Ephedrine in chloroform has been found to be a suitable sc:vent for silver diethyldithiocarbamate if the analyst finds the odor of pyridine obknionable [Anal. Chem.45, 1786(1973)]. 3.5 For quality control requirements and optional recommendations for use in drinking water analyses, see part 10 of the Atomic Absorption Methods section cf this manual. coved for NPDES and SDWA r.v-th 1971 al-orial revision 1974 32 206.4-1 c Precision and Accuracy 4.1 In a round-robin study rcportcd by Standard Mcthods a synthetic unknown sample containing 40 ug/l, as As, with othcr metals was analyzed in 46 laboratories.

~~METHOD 7471~~

~~MERCURY IN SOLID OR SEMISOLID WASTE (MANUAL COLD-VAPOR TECHNIQUE)~~

~~1.0 Scope and Application~~

1.1 Method 7471 is approved for measuring total mercury (organic and inorganic) in soils, sediments, bottom deposits, and sludge-type materials. All samples must be subjected to an appropriate dissolution step prior to analysis.

~~2.0 Summary of Method~~

~~2.1 Prior to analysis the samples must be prepared according to the procedures discussed in this method.~~

~~2.3 The typical detection limit for this method is 0.0002 mg/1.~~

~~3.0 Interferences~~

~~3.2 Copper has also been reported to interfere; however, copper concentrations as high as 10 mg/1 had no effect on recovery of mercury from spiked samples.~~

3.3 Seawaters, brines, and industrial effluents high in chlorides require additional permanganate (as much as 25 ml) since, during the oxidation step, chlorides are converted to free chlorine which also absorbs radiation of 253 nm. Care must therefore be taken to ensure that free chlorine is absent before the mercury is reduced and swept into the cell. This may be accomplished by using an excess of- hydroxylamine sulfate reagent (25 ml). In addition, the dead air space in the BOO bottle must be purged before adding stannous sulfate. Both inorganic and organic mercury spikes have been quantitatively recovered from seawater using this technique.

~~3.4 Certain volatile organic materials that absorb at this wavelength may also cause interference. A preliminary run without reagents should determine if this type of interference is present.~~

34 o o 4.0 Apparatus and materials O 4.1 Atomic absorption spectrophotometer or equivalent: Any atomic Cr; absoption unit having an open sample presentation area in which to mount the absorption cell is suitable. Instrument settings recommended by the particular manufacturer should be followed. Instruments designed specifically for the measurement of mercury using the cold-vapor technlque are commercially available and may be substituted for the atomic absorpti.on spectrophotometer.

~~4.2 Mercury hollow cathode lamp or electrodeless discharge lamp.~~

~~4.3 Recorder: Any multirange variable speed recorder that is compatible with the UV detection system is suitable.~~

4.4 Absorption cell: Standard spectrophotometer cells 10 cm long having quartz end windows may be used. Suitable cells may be constructed from plexiglass tubing, 1 in. 0.0. x 4.5 in. The ends are ground perpendicular to the longitudinal axis and quartz windows (1 in. diameter x 1/16 in. thickness) are cemented in place. The cell is strapped to a burner for support and aligned in the light beam by use of two 2-in. x 2-in. cards. One-in.-diameter holes are cut in the middle of each card. The cards are then placed over each end of the cell. The cell is then positioned and adjusted vertically and horizontally to give the maximum transmittance.

~~4.5 Air p-mp: 'Any peristaltic pump capable of delivering 1 liter air/min may be used. A Masterflex pump with electronic speed control has been foird to be satisfactory.~~

~~4.6 Flowmeter: Capable of measuring an air flow of 1 liter/min.~~

~~4.7 Aeration tubing: A straight glass frit having a coarse porosity. Tygon tubing is used for passage of the mercury vapor from the sample bottle to the absorption cell and return.~~

~~4.9 The cold-vapor generator is assembled as shown in Figure 1.~~

~~4.10 The apparatus shown in Figure 1 is a closed system. An open system, where the mercury vapor is passed through the absorption cell only once, may be used instead of the closed system.~~

~~5.0 Reagents~~

~~5.1 ASTM Type II water (ASTM D1193): Water should be monitored for impurities.~~

~~5.2 Aqua regia: Prepare immediately before use by carefully adding three volumes of conc. HC1 to one volume of conc. HNO3.~~

~~5.3 Sulfuric acid, 0.5 N: Dilute 14.0 ml of conc. sulfuric acid to 1 liter.~~

5.4 Stannous sulfate: Add 25 g stannous sulfate to 250 ml of 0.5 N sulfurjc acid. This mixture is a suspension and should be stirred continu- ously during use. A 10% solution of stannous chloride can be substituted for tannous sulfate.

5.5 Sodium chloride-hydroxylamine sulfate solution: Dissolve 12 g of sodium chloride and 12 g of hydroxylamine sulfate in Type II water and dilute to 100 ml. Hydroxylamine hydrochloride may be used in place of hydroxylamine sulfate.

~~5.6 Potassium permanganate, 5% solution (w/v): Dissolve 5 g of potassium permanganate in 100 ml of Type II water.~~

~~5.7 Mercury stock solution: Dissolve 0.1354 g of mercuric chloride in 75 ml of distilled water. Add 10 ml of conc. nitric acid and adjust the volume to 100.0 ml (1.0 ml = 1.0 mg Hg).~~

5.8 Mercury working standard: Make successive dilutions of the stock mercury solution to obtain a working standard containing 0.1 pg/ml. This working standard and the dilution of the stock mercury solutions should be prepared fresh daily. Acidity of the working standard should be maintained at 0.15% nitric acid. This acid should be added to the flask as needed before adding the aliquot.

~~37 METHOD 7741 Appendix 1.5 SELENIUM (ATOMIC ABSORPTION, GASEOUS HYDRIDE)~~

~~.0) Scope and Application~~

~~2.0 Summary of Method~~

2.1 Samples are prepared according to the nitric/sulfuric acid digestion procedure described in this method. Next, the selenium in the digestate is reduced to the +4 form using tin chloride. The +4 selenium is then converted to a volatile hydride with hydrogen produced from a zinc/HC1 reaction,

~~2.3 The typical detection limit for this method is 0.002 mg/1.~~

~~3.0 Interferences~~

~~3.1 High concentrations of chromium, cobalt, copper, mercury, molybdenun nickel, and silver can cause analytical interferences.~~

~~3.2 Traces of nitric acid left following the sample workup can result in analytical interferences. Nitric acid must be distilled off by heating the sample until fumes of S03 are observed.~~

~~3.3 Elemental selenium and many of its compounds are volatile and therefore certain samples may be subject to losses of selenium during sample preparation.~~

~~4.0 Apparatus and Materials~~

~~4.1 100-m1 beaker.~~

~~4.2 Electric hot plate.~~

~~4.3 A commercially available zinc slurry hydride generator or a generator constructed from the following material (see Figure 1).~~

~~38 7.2 Prepare working standards from the standard stock solutions. The following procedure provldes standards in the optimum working range.~~

7.2.1 Pipet 1 ml stock solution into a 1-liter volumetric flask. Bring to volume with Type II water containing 1.5 ml conc. HNO3/liter. The concentratlon of this solution is 1 mg Se/liter (1 ml = 1 pg Se).

7.2.2 Prepare six working standards by transferring 0, 0.5, 1.0, 1.5, 2.0 and 2.5 ml of the selenium stock standard (see Section 5.8) into a 100-m1 volumetric flasks. Bring to volume with diluent. The concentrations of these working standards are 0, 5, 10, 15, 20 and 25 pg Se/liter.

~~7.3 Standard additions~~

~~7.3.2 Add 10 ml of prepared sample to a 50-ml volumetric flask. Bring to volume with Type 11 water containing 1.5 ml HNO3 per liter. This is the blank.~~

7.4 Follow the manufacturer's instructions for operating an argon- hydrogen flame. The argon-hydrogen flame is colorless so it may be useful to aspirate a lowconcentration of sodium to ensure that ignition has occurred.

~~7.5 The 196.0-nm wavelength shall be used for the analysis of selenium.~~

~~7.7 Analyze, by the method of standard additions; all EP extracts, all samples analyzed as part of a delisting petition, and a11 samples that suffer from matrix interferences.~~

~~7.8 Duplicates, spiked samples, and check standards should be routinely analyzed.~~

~~39 o o 5.6 Potassiun iodide solution: Dissolve 20 g~~

5.8 Selenium standard stock solution: 1000 mg/liter solution may be purchased, or prepared as follows. Dissolve 0.3453 g of selenious acid (assay 94.6% of N2Se01) in Type II water. Add to a 200-ml volumetric flask and bring to volume (1 ml = 1 mg Se).

~~6.0 Sample Collection, Preservation, and Handling~~

~~6.1 All samples must have been collected using a sampling plan that addresses the considerations discussed in Section One of this manual.~~

~~6.2 All sample containers must be prewashed with detergents, acids, and Type II water. Plastic and glass containers are both suitable.~~

~~6.3 Special containers (e.g., containers used for volatile organic analysis) may have to be used if very volatile selenium compounds are to be analyzed.~~

~~6.4 Aqueous samples must be acidified to a pH of less than 2 with nitric acid.~~

~~6.5 Nonaqueous samples shall be refrigerated where possible, and malyzed as soon as possible.~~

~~.0 Procedure~~

~~7.1 Sample preparation~~

7.1.1 To a 50 ml aliquot of digested sample (or in the case of EP extracts a 50-ml sample) add 10 ml conc. NNO3 and 12 ml of 18 N H2SO4. Evaporate the sample on a hot plate until white S03 fumes are observed (a volume of about 20 ml). Do not let it char. If it chars, stop the digestion, cool and add additional HNO3. Maintain an excess of HNO3 (evidence of brown fumes) and do not let the solution darken, because selenium may be reduced and lost. When the sample remains colorless or straw yellow during evolution of S03 fumes, the digestion is complete.

7.1.2 Cool the sample, add about 25 ml distilled deionized water and again evaporate to SO3 fumes just to expel oxides of nitrogen. Cool. Add 40 ml conc. NCI and bring to a volume of 100 ml with distilled deionized water.

~~Method 352.1 (Colorimetric, Brucine)~~

~~STORET NO. Total 00620~~

1. Scope and Application 1.1 This mcthod is applicablc to the analysis of drinking, surface and saline waters, domestic and industrial wastes. Modification can be made to remove or correct for turbidity, color, salinity, or dissolved organic compounds in the sample. 1.2 The applicable range of concentrations is 0.1 to 2 mg NO3—N/liter. 2. Summary of Method 2.1 This method is based upon the reaction of the nitratc ion with brucine sulfate in a 13 N I-12SO,solution at a temperature of 100°C. The color of the resulting cornplex is measured at 410 nrn. Temperature control of the color reaction is extremely critical. 3. Sample Handling and Preservation 3.1 Analysis should be made as soon as possible. If analysis can be made within 24 hours, the sample should be preserved by refrigeration at 4°C. When samples must be stored for more than 24 hours, they should be preserved with sulfuric acid (2 ml conc. H2SO4 per liter) and refrigeration. 4. Interferences 4.1 Dissolved organic matter will cause an off color in 13 N H2SO4 and must be compensated for by additions of all reagents except the brUcine-sulfanilic acid reagent. This also applies to natural color present not due to dissolved organics. 4.2 The effect of salinity is eliminated by addition of sodium chloride to the blanks, standards and samples. 4.3 A11 strong oxidizing or reducing agents interfere. The presence of oxidizing agents may be determined with a total residual chlorine test kit. 4.4 Residual chlorine interference is eliminated by the addition ofsodium arsenite. 4.5 Ferrous and ferric iron and quadrivalent manganese give slight positive interferences, but in concentrations less than 1 mg/I these are negligible. 4.6 Uneven heating of the samples and standards during the reaction time will result in erratic values. The necessity for absolute control of ternperature during the critical color t development period cannot be too strongly emphasized. 5. Apparatus 5.1 Spectrophotometer or filter photorneter suitable for measuring absorbance at 410 nm. 5.2 Suflicient nurnber of 40-50 ml glass sample tubes for reagent blanks, standards and samples. 5.3 Neoprene coated wire racks to hold sample tubes. 5.4 Water bath suitable for use at 100°C. This bath should contain a stirring mechanism so that all tubes are at the same tcmperature and should be of sufficient capacity to accept

Reagcnts O 6.1 Distilled water free of nitrite and nitrate is to be used in preparation of aIl reagents and standards. 6.2 Sodium chloride solution (30%): Dissolve 300 g NaCI in distilled water and dilute to 1 liter. 6.3 Sulfuric acid solution: Carefully add 500 ml conc. H2S0, to 125 ml distilled water. Cool and kecp tightly stoppered to prevent absorption of atmospheric moisture. 6.4 Brucine-sulfanilic acid reagent: Dissolve 1 g brucine sulfate [(C231426N2002-H2SO4-7H20] and 0.1 g sulfanilic acid (NEI,C61-14S03H-H20) in 70 ml hot distilled water. Add 3 ml conc. HCI, cool, mix and dilute to 100 ml with distilled water. Store in a dark bottle at 5t. This solution is stable for several months; the pink color that develops slowly does not effect its usefulness. Mark bottle with warning CAUTION: Brucine Sulfate is toxic; take care to avoid ingestion. 0 6.5 Potassium nitrate stock solution: 1.0 ml = 0.1 mg NO3-N. Dissolve 0.7218 g anhydrous potassium nitrate(KNO 3)in distilled water and dilute to 1 liter in a volumetric flask. Preserve with 2 ml chloroform per liter. This solution is stable for at least 6 months. 6.6 Potassium nitrate standard solution: 1.0 ml = 0.001 mg NO3-N. Dilute 10.0 ml of the stock solution (6.5) to I liter in a volumetric flask. This standard solution should be Y-7 C prepared fresh weekly. \j/ ,/1 6.7 Acetic acid (1 + 3): Dilute 1 volume glacial acetic acid (CH3COOH)with 3 volumes of -3 /0 distilled water. 6.8 Sodium hydroxide(IN): Dissolve 40 g of NaOH in distilled water. Cool and dilute to 1 liter. 7. Procedure 7.1 Adjust the pH of the samples to approximately 7 with acetic acid (6.7) or sodium hydroxide(6.0. If necessary, filter to remove turbidity. 7.2 Set up the required number of sample tubes in the rack to handle reagent blank, standards and samples. Space tubes evenly throughout the rack to allow for even flow of bath water between the tubes. This should assist in achieving uniform heating of all tubes. 7.3 If it is necessary to correct for color or dissolved organic matter which will cause color on heating, a set of duplicate samples must be run to which all reagents except the brucine- sulfanilic acid have been added. 7.4 Pipette 10.0 ml of standards and samples or an aliquot of the samples diluted to 10.0 ml into the sample tubes. 7.5 If the samples are saline, add 2 ml of the 30% sodium chloride solution (6.2) to the reagent blank, standards and samples. For fresh water samples, sodium chloride solution may be omitted. Mix contcnts of tubes by swirling and place rack in cold water bath (0-10t).

352.1-2 42 c c 7.6 Pipcttc 10.0 ml of sulfuric acid solution (63)into cach tube and mix by swirling. Allow tubes to come to thermal equilibrium in the cold bath. Be sure that temperatures have equilibrated in all tubes before continuing. 7.7 Add 0.5 ml brucine-sulfanilic acid reagent (6.4) to each tube (except the interference control tubes, 7.3)and carefully mix by swirling, thcn place the rack of tubes in the 100t watcr bath for exactly 25 minutes. Caution: Immersion of the tube rack into thc bath should not decrease the temperature of the bath more than I to 2°C. In order to kecp this temperature decrease to an absolute minimum,flow of bath water bctween the tubes should not be restricted by crowding too many tubes.into the rack. If color development in the standards reveals discrepancies in the procedure, the operator should repeat the procedure after reviewing the temperature control steps. 7.8 Remove rack of tubes from the hot water bath and immcrse in the cold water bath and allow to reach thermal equilibrium (20-25°C). 7.9 Read absorbance against the reagent blank at 410 nm using a 1 cm or longer cell. 8. Calculation 8.1 Obtain a standard curve by plotting the absorbance 'of standards run by the above procedure against mg NO3-N/1.(The color reaction does not always follow Beer's law). 8.2 Subtract the absorbance of the sample without the brucine-sulfanilic reagent from the absorbance of the sample containing brucine-sulfanilic acid and determine mg NOrN/1. Multiply by an appropriate dilution factor if less than 10 ml of sample is taken. 9. Precision and Accuracy 9.1 Twenty-seven analysts in fifteen laboratories analyzed natural water samples containing exact increments of inorganic nitrate, with the following results:

~~Purpose of Conversation: Asbestos Abatement in Chemical Trench at CPP-621~~

Text of Conversation: Mark described the project that took place in the Chemical Trench south of CPP 621. The project took place during the months of September, October and November 1993. The project removed asbestos from lines in the trench and replaced them with nonasbestos insulation. Also during the project approximately 2" of soil was removed from the entire area of the trench to remove any asbestos that may have fallen to the ground. The area within the trench was covered with plastic and sand is planned to be put on top the plastic.

~~Dear Joan:~~

Enclosed, please find a preliminary scope of work and budget for the work you requested UURI perform at CPP site 621. The proposed work is comprehensive and has been divided into four components; pre-sampling activities (Phase I), targeted sampling within the site and on its perimeter (Phase II), intermediate depth/slant drilling (Phase III), and the preparation of a final report and closure plan (Phase IV). In our opinion, it will be most cost effective to develop a program with these components now if the decision is made by WINCO to bring the site into compliance with EPA standards. This compliance will probably require refurbishing the containment facilities, chemical trenches, and pump houses as well as characterizing and remediating the site. This may be much more difficult and costly if the construction is completed as presently planned. You should, in addition, keep in mind as you review the sampling plan which we have outlined that the layout of the site places limits on the location and depth of the samples that can be collected. Thus, there will be some gaps in the data especially in the central portions of the area and beneath the limestone pits. EPA may require WINCO to close these gaps with additional data before approving any closure plans.

I have included costs for preparing a site safety plan for WINCO's approval as we discussed during our meeting with you last week. However, because WINCO is responsible for overall site safety at the CPP facility, we feel that WINCO should provide a Site Safety Officer during sampling activities, and approve and implement any site safety plans that we prepare at your request. It is our understanding that WINCO will assume the liability for safety on the site. We do, however, want the option of stopping sampling activities by our staff at the site without penalty if, in our opinion, a dangerous situation should develop.

The sampling program we have designed will involve: hand augering; deep augering to approximately 40 feet; and intermediate depth or slant augering to c c 20-30 feet. Samples with a hand auger will be taken at the surface and at a depth of approximately 3 feet throughout the area, including the limestone C- pits, french drains, sludge pit, and chemical trenches. We anticipate collecting approximately 110 hand auger samples. Cc

Deep augering samples will be obtained around the perimeter of the site and if possible, adjacent to and in the limestone pit. Because the clay layer at 40 to 45 feet acts as a barrier to downward percolating contamination, we plan to auger no deeper than the top of this layer. This deep drilling will establish the maximum extent of contamination.

In the center of the site where the space between the tanks is narrow, a small drill rig will be required. We have located a rig suitable for this work but its depth capabilities are limited and because of its small size, drilling will be slow and therefore costly. If possible, use of this rig should be delayed until data from the hand augered and deep samples are obtained, since information on the full extent of contamination in the area may not be needed if contamination exists at depth.

We have assumed in preparing the budget that you will provide the manual labor and construction materials needed to obtain some of the samples. This work will involve: removal of some of the beams and metal posts; removal of the limestone from two sample locations in each of the limestone pits; removal of portions of the trench covers during trench sampling; and pumping and barreling of the sludge in the sludge pit so that the bottom can be sampled.

I understand that the Hawley Bros. would be available to do the deep drilling around the middle of September. The paperwork and hand augering could be started as soon as we have a contract in place. If you need additional information or more detailed cost breakdown please let me know.

~~From D. J. Poland ERC r COPY Phone : 6-3650/CPP-630 Nm . September 1, 1987 SuNect Characterization of the CPP-621/637 Areas~~

~~(Of"' Ra, c1, To J. W. Ruffner GP&CE Projects~~

The characterization of the solid waste man gement units (SWMUs), CPP-621 chemical storage area and the CPP-637 courtyard (spill 1978), requested by Projects because of pending construction (secondary containments) and conducted by the University of Utah Research Institute (UURI) (report attached), has been completed and the following is a summary of this characterization:

• Sample analyses have been statistically compared to the concentrations found in the background samples. These analyses indicated higher than background levels of mercury In the three aluminum nitrate French drains, higher than background levels of fluoride in the hydrofluoric acid containment, higher than background levels of nitrate and lead in the chemical trench, and higher than background levels of nitrate in the sludge pit. The analyses results of the soil samples collected from the CPP-637 courtyard area indicate higher than background levels of zirconium, aluminum, chromium, and arsenic.

~~A cleanup was conducted in the CPP-621 aluminum nitrate French drains. This remedial action (conducted by UURI) draft final report is attached and states in part the following:~~

~~• Soil excavated from the three aluminum nitrate French drains contained mercury at greater than background levels.~~

• The average mercury concentration of unexcavated soil is <58.3 ppb. This value is approximately equal to the background mean + 2 standard deviations and is within the range of Hg contents of soils developed over volcanic rocks.

~~In conclusion, the following assumptions can be made:~~

• The aluminum nitrate French drains have been cleaned up to background levels. Construction may proceed in this area but be aware that construction in a solid waste management unit is always at a risk without prior EPA approval. See attached letter from A. J. Matule to

~~®! Westinghouse Idaho Nuclear Company. Inc. cep: zs C: J. W. Ruffner C OJP-01-87 September 1, 1987 Page 2 cr~~

P. I. Nelson for information on risks involved. Since the characterization of the sites following cleanup has been conducted by a recognized expert with experience in these activities, Environmental Engineering believes the risks of non approval by EPA to be minimal.

Further characterization and/or cleanup is necessary in the HF containment, chemical trench, sludge pit, and CPP-637 courtyard. However, in the CPP-637 courtyard a temporary stainless steel catch basin may be installed under the two zirconium feed tanks until a characterization/cleanup has been conducted. Additional guidance for the HF pit will be forthcoming.

No hazardous constituents above background levels were detected in the area of the nitric acid tanks and sulfuric and hydrochloric acid containment. Construction may proceed in these areas but be aware that construction in a solid waste management unit is always at a risk without prior EPA approval. However, because the characterization was conducted by a recognized expert with experience in these activities, Environmental Engineering believes the risk of non approval by EPA to be minimal.

It and III require negotiation with Analytical to establish a quality control program suitable for your samples. Most non-process related samples are Duality Level IV. °utility Level I: Results are produced by two independent analysis methods which are tested statistically against pre-established limits at specified confidence levels. Level IL Results are produced with a bias correction and precision estimate obtained through a quality control program and the results are tested against pre-established limits at specified confidence levels. Level III. Results are produced with a bias correction and precision estimate obtained through a quality control program. Lt, JO IV: Results are produced without bias correction and precision estimate.

~~Purpose of Conversation: Source of 4-X-X sample analysis in Chemical Storage And Zirconium Feed Tank Storage Area Final Report (September 1987)~~

Text of Conversation: I asked Joe about the chronology of sampling activities at the ICPP that UURI did in 1986 & 87. Joe referred to a report as we talked and confirmed that the samples in the September 87 final report were analyzed by UURI at the same time that the samples taken by UURI in April 87 were analyzed. He confirmed that these samples were not taken by UURI but were given to him by Joan Poland. He remembered Joan discussing that the samples were taken before by Hawley Bros. and remembered looking at the sampling locations still visible in the roadways. (These were the drill locations done by Hawley in March and April of 86, WINCO ERC DCN #01588).

(Golder Associates) at the Solid Waste Management Unit(SWMU) CPP-45 were to evaluate the nature and extent of soil contamination of the known or suspected wastes in the add storage vaults CPP-757 and CPP-727 and in doing so characterize the vaults to determine whether any remediation under RCRA is required. This work was performed in accordance with the Technical Work Plan for the Idaho Chemical Processing Plant Soil Sampling and Analysis Program at Solid Waste Management Unit CPP-45 (Golder Associates 1990a, 1990b).

~~1.2 Organization of the Report~~

This report presents general information on the site and the physical setting, a description of sampling and analysis procedures, a description of the nature and extent of the contamination, a health and environmental assessment and a summary and conclusions. The conclusions detail our recommendations for further work at the site. Borehole logs and laboratory analytical results are presented in the Appendices.

~~2. SITE BACKGROUND AND PHYSICAL SETTING~~

~~2.1 Idaho Chemical Processing Plant~~

~~2.1.1 Regional Geology~~

The Idaho Chemical Processing Plant (ICPP) is located in the southern portion of the Idaho National Engineering Laboratory (INEL) site that occupies approximately 890 square miles of the northwestern portion of the Eastern Snake River Plain in southeast Idaho (Figure 2.0). The plain is a structural and topographic basin approximately 200 miles long and 50 to 70 miles wide. Surficial sediments range from 0 to 345 feet thick at the INEL. Underlying the surficial sediments are 2,000 to 10,000 feet of basalt flows, rhyolitic rocks, tephra, and interbedded alluvium and lacustrine deposits (Mundorff et al., 1964; Bartholomay et al., 1989; Pittman et al., 1988).

The ICPP is located on alluvial sediments deposited by the Big Lost River or on fill materials. Surficial sediments at the ICPP can be divided into two distinct layers. The coarse grained surficial layer extends to a depth of 35 to 40 feet and is composed of sands and gravels with a trace of silt and clay. The underlying layer is made up of clayey sands and sand-clay mixtures and ranges from zero to ten feet in thickness and overlies the Snake River Plain basalts. The contact between the basalts and the overlying sediments generally occurs at a depth of 45 to 50 feet below the original land surface (WINCO 1989a, 1989b).

Sedimentary interbeds are common within the Snake River basalts. In the area of the ICPP, a 15 to 30 foot thick clayey interbed occurs at a depth of approximately 110 feet below land surface. The sequence of interbedded basalts and sedimentary interbeds continues to well below the water table. There is evidence of a sedimentary interbed at a depth of 750 feet below land surface (WINCO, 1989a, 1989b).

~~2.1.2 Regional Hydrology~~

~~Surface Water~~

The Big Lost River is the major surface water feature on the INEL with its headwater located west of the site. The Big Lost River flows to the southeast past the town of Arco, Idaho onto the Snake River Plain then turns to the northeast flowing onto the INEL and terminating in three playa lakes. Where the river flows onto the plain, the main channel branches into many distributaries and the flow is spread broadly, losing water by infiltration into the channel bottom (Pittman et al., 1988). The Big Lost River is ephemeral with flow onto the site only during periods of high runoff. The INEL Diversion Dam is located approximately 9 miles upstream from the ICPP and was designed to control flooding on the INEL site by diverting water into designated spreading areas.

~~Hydrogeology~~

The depth to the water table of the Snake River Plain aquifer in the area of the ICPP is approximately 455 feet below land surface based on 1990 water level measurements made by Golder Associates. The direction and rate of groundwater movement in the vicinity of the ICPP is documented from monitoring contaminant plumes in the Snake River aquifer. The rate of flow ranges from 5 to 15 ft/day in a direction from north-northeast to the south- southwest (Pittman et aL, 1988).

Two perched water tables are known to exist at the ICPP. The geologic layers responsible for these water thbles are at the interface between the surficial sediments and the top of the uppermost basalt layer, and at the interface between the 110 foot interbed and the overlying basalts. The direction of flow and extent of these perched zones is not known.

~~2.2 Solid Waste Management Unit(SWMU) CPP-45~~

~~2.2.1 Location and Description of SWMU CPP-45~~

SWMU CPP-45 is located north of the CPP-607 building at the ICPP and is illustrated on Figures 2.1 and 2.2. Acid storage tank vaults CPP-757 and CPP-727 are located in the south portion of SWMU CPP-45. The storage tanks have been removed from storage vault CPP- 757 only.

~~2.2.2 Location and Description of Add Storage Tank Vault CPP-757~~

Acid storage tank vault CPP-757 is located in the southeast portion of SWMU CPP-45. The storage vault walls are constructed of concrete with an uneven, coarse gravel floor. The vault is approximately 14 feet wide and 39 feet long with a maximum depth of about 6 feet.

~~The vault once contained hydrochloric acid (HO) and sulfuric acid (H2SO4)storage tanks. The tanks have since been removed and the vault is presently empty.~~

~~2.2.3 Known or Suspected Wastes Associated with Acid Storage Tank Vault CPP-757~~

A spill of about 300 gallons of concentrated sulfuric add reportedly occurred in 1986. Other spills of hydrochloric ac➢d or sulfuric add may have occurred within the vault and not been reported. Hydrochloric add and sulfuric add could be classified as characteristic hazardous wastes (D002) due to corrosivity.

Preliminary surface sampling of the soils at two locations underlying the storage tank vault (Figure 2-3) had been performed prior to this investigation (UURI 1987). Analysis of these samples for pH, mercury, and nitrate-nitrogen indicated the presence of low concentrations of mercury and nitrates. Mercury concentrations were above a preliminary determination of background levels at one location (Table 2-1).

~~2.2.4 Location and Description of Acid Storage Tank Vault CPP-727~~

Acid storage tank vault CPP-727 is located in the southwest portion of SWMU CPP-45. The vault walls are constructed of concrete with a flat, native soil floor with a cover of limestone rock directly below the tank The vault is approximately 16 feet wide, 27 feet long and 8 feet deep.

~~The vault contains a horizontal hydrofluoric add storage tank. Associated valves are located at the northwest and northeast portions of the vault.~~

~~2.2.5 Known or Suspected Wastes Associated with Acid Storage Tank Vault CPP-727~~

A documented spill of approximately 4 gallons of hydrofluoric acid occurred at the west end of the vault and other spills may have occurred but are not recorded. Hydrofluoric acid is classified as a listed waste (U134).

Preliminary surface sampling of the soils at three locations within the vault (Figure 2-3) had been performed prior to this investigation (UURI 1987). Analysis of these sample for pH, metals and fluoride ions indicated the presence of hydrofluoric acid in the western and northern portions of the vault (Table 2-1).

~~3. SAMPLING AND ANALYSIS~~

~~3.1 Objectives~~

The objective of the sampling effort at SWMU CPP-45 acid storage containment vault CPP- 757 and vault CPP-727 was to determine if adds or miscellaneous chemicals have been released to the soil and are presently in concentrations above regulatory action levels requiring RCRA remediation prior to any further construction activities.

~~The characterization efforts focused on the tank and valve locations within the containment vault, considered the most likely sources of potential contamination.~~

~~3.2 Soil Sampling Methods and Locations~~

~~3.2.1 Sample Collection at SWMU CPP-45 Add Storage Tank Vault CPP-757~~

~~The chosen method of sampling in vault CPP-757 was hand augering. This method was chosen over hollow stem auger drilling due to limited accessibility in the vault.~~

Soil sample locations are shown on Figure 3.0. The individual locations were chosen in areas of the vault that were near low points, in close proximity to valves or where discoloration in the soil was noted. All borings were augered to a depth of six feet or until refusal. Sample collection intervals were 0-2 feet, 2-4 feet, and 4-6 feet. Samples were taken with either a 0.41 foot, 0.33 foot or a 0.15 foot diameter auger. All samples were screened by WINCO Health Physics personnel to detect radiation levels above background level.

Sampling equipment and sample preparation tools were decontaminated between each sample interval to minimize the potential for cross contamination. Augering and sampling decontamination procedures are referenced in Section 4.6 of the Technical Work Plan, Volume II (Golder Associates 1990b).

~~3.3 SWMU CPP-45 Site Geology~~

~~3.3.1 SWMU CPP-45 Acid Storage Tank Vault CPP-757 Site Geology~~

CPP-757 is located on about six inches to one foot of granular fill which overlies alluvial sediments deposited by the Big Lost River. The fill material is comprised of sands similar in compositions to those found in the native alluvium and was probably derived from a local source.

Two six foot borings (CPP45-03 and CPP45-04) and one three foot boring (CPP45-05) were augered and sampled in the vault. The alluvial sediments in the vault generally consisted of well graded fine to coarse gravel and medium to coarse sand. No groundwater was encountered in the borings.

Upon completion of the drilling and sampling the borings were left open since weather conditions were unfavorable for filling the holes and forthcoming construction activities would excavate beyond the depths of the borings.

~~3.3.2 SWMU CPP-45 Acid Storage Tank Vault CPP-727 Site Geology~~

CPP-727 is located on about six inches to one foot of granular fill which overlies alluvial sediments deposited by the Big Lost River. The fill material is comprised of sands similar in compositions to those found in the native alluvium and was probably derived from a local source. Directly below and adjacent to the arid storage tank the vault bottom was lined with a layer of 4 inch or greater limestone cobble.

Three borings (CPP 45-01, CPP 45-02 and CPP 45-03) were augered to approximately 1.5 feet but terminated due to ground conditions or underground wiring. Two additional borings (CPP 45-01A and CPP 45-02A) were augered to a depth of 6 feet. The alluvial sediments in the vault generally consisted of well graded fine to coarse gravel and medium to coarse sand. No groundwater was encountered in the borings.

~~3.4 SWMU CPP-45 Sample Handling and Analysis~~

~~3.4.1 Sample Handling and Analysis, CPP-757~~

Samples were obtained by augering to the desired sampling interval and, using a decontaminated hand auger, sampling one auger volume of the boring material. Samples were obtained from borings 03 and 04 from the surface to 2 foot, 2 to 4 foot and 4 to 6 foot intervals and from boring 05 from the surface to 2 foot and 2 to 4 foot intervals. Samples were processed on a fresh length of protective plastic on the processing table. The upper two inches of material in the auger was discarded. The sample was then placed into a decontaminated stainless steel mixing bowl, mixed thoroughly using decontaminated stainless steel utensils, and granular material larger than two inches was discarded. Sample was then transferred to two 8 ounce glass jars for analysis for total metals, pH, chloride and sulfate.

Samples from the surface to 2 foot interval on boring 5 were also prepared for Appendix VIII analyses. Grab samples were immediately taken for Appendix VIII volatile organics and placed in 8 ounce glass jars. Sample was placed in the containers such that little or no headspace was present, the containers were immediately sealed with a teflon lined lid and temporarily placed in the shipping containers. Ambient temperatures were such that no coolant was required in the shipping containers prior to actual shipment to the laboratory.

The remaining sample material was transferred to a plastic container for Appendix VIII pH, CI, SO„ metals, cyanide and sulfide analyses and to two 8 ounce glass jars for Appendix VIII semivolatiles, pesticides and herbicides and Appendix VIII dioxins and furans. Any remaining sample material was discarded into a 50 gallon waste container for subsequent disposal by WINCO personnel. All samples were labeled and placed into the appropriate shipping container with the necessary amount of coolant for maintaining the samples at 4°C. Sample were packed in bubble wrap for protection during shipment. Samples were then transferred by overnight carrier under chain-of-custody to the analytical laboratory.

All samples obtained were analyzed by Pacific Northwest Environmental Laboratory, Inc. (PNELI) of Redmond, Washington for the constituents listed in Table 3-1 with the exception of the surface sample obtained from boring 05. The surface to 2 foot sample collected from boring 05 was analyzed by Gulf South Environmental Laboratory, Inc.(GSELI) of New Orleans, Louisiana and by Southwest Laboratory of Oklahoma, Inc(SWLO) of Tulsa, Oklahoma for the 40 CFR Part 261 Appendix VIII constituents.

Results of the analysis indicating the target compounds detected and the range of values are presented in Table 4-2. Copies of all laboratory data reports are provided in Appendix C. A discussion of the analytical results is presented in Section 4.

~~3.4.2 Sample Handling and Analysis, CPP-757~~

Samples were obtained by augering to the desired sampling interval and, using a freshly decontaminated hand auger, sampling one auger volume of the boring material. Samples were obtained from borings 01, 02 and 06 from the surface to 2 foot depth and from borings 01A and 02A from the 2 to 4 foot and 4 to 6 foot intervals. Samples were processed on a fresh length of protective plastic on the processing table. The upper two inches of material in the auger was discarded. The sample was then placed into a decontaminated stainless steel mixing bowl, mixed thoroughly using decontaminated stainless steel utensils, and granular material larger than two inches was discarded. Sample was then transferred to two 8 ounce glass jars for analysis for total metals, pH, and fluoride.

Samples from the surface to 2 foot interval on boring 06 were also prepared for Appendix VIII analyses. Grab samples were immediately taken for Appendix VIII volatile organics and placed in 8 ounce glass jars. Sample was placed in the containers such that little or no headspace was present, the containers were immediately sealed with a teflon lined lid and temporarily placed in the shipping containers. Ambient temperatures were such that no coolant was required in the shipping containers prior to actual shipment to the laboratory.

The remaining sample material was transferred to a plastic container for Appendix VIII pH, Cl, SO„ metals, cyanide and sulfide analyses and to two 8 ounce glass jars for Appendix VIII semivolatiles, pesticides and herbicides and Appendix VIII dioxins and furans.

Any remaining sample material was discarded into a 50 gallon waste container for subsequent disposal by WINCO personnel. All samples were labeled and placed into the appropriate shipping container with the necessary amount of coolant for maintaining the samples at 4°C. Sample were packed in bubble wrap for protection during shipment. Samples were then transferred by overnight carrier under chain-of-custody to the analytical laboratory.

All samples obtained were analyzed by Pacific Northwest Environmental Laboratory, Inc. (PNELI) of Redmond, Washington for the constituents listed in Table 3-1 with the exception of the surface sample obtained from boring 06. The surface to 2 foot sample collected from boring 06 was analyzed by Gulf South Environmental Laboratory, Inc. (GSELI) of New Orleans, Louisiana and by Southwest Laboratory of Oklahoma, Inc(SWLO) of Tulsa, Oklahoma for the 40 CFR Part 261 Appendix VIII constituents.

~~3.5 Quality Assurance/Quality Control~~

~~Quality assurance/quality control procedures were implemented during the sampling and analysis program. These procedures are summarized below.~~

~~Golder Associates lanuaty 31, 1991 16 893-1195.900~~

• A trip blank and an equipment blank were collected and analyzed to monitor potential contamination that may have been introduced from the decontamination procedures and shipping process (see section 3.5.1).

~~• A field duplicate sample was collected to measure overall field and laboratory precision (see Table 3-2).~~

~~• A blind reference performance audit sample was prepared and submitted for metals analysis to determine laboratoty accuracy (see Table 3-3).~~

~~3S.1 Blanks~~

A trip blank was included in the sample shuttle for organic analysis. Methylene chloride (20 uWL) was detected in the trip blank sample and also detected in the volatile method blanks at 14 and 7 ug/L respectively.

An equipment blank was submitted for one sampling round for metals and conventional parameters. The blank was prepared by thoroughly cleaning the drilling and sampling equipment prior to each sampling event as described in Section 4.6 of the Quality Assurance Project Plan (Golder Associates, 1990) followed by a final rinse with deionized water and collection of the rinseate in the proper containers for metals and conventional parameters analysis (Ph, chloride, sulfate, fluoride). Barium and iron were detected in the equipment blank at 16.8 ug/L and 62.5 ug/L respectively. Both of these values reported are obtained from a reading that was less than the Contract Required Detection Limit(CRDL) but greater than or equal to the Instrument Detection Limit (IDL). Iron is commonly found in the alloys used for fabrication of drilling and sampling equipment. Fluoride and chloride were reported at 0.531 mWL and 0.120 mg/L. These levels are significantly lower than the levels found in the soil samples collected at the site.

~~3.5.2 Field Duplicates~~

Field duplicate results from SWMU CPP-45 are presented in Table 3-2. The samples were collected and prepared as described in Section 4.4 of the Quality Assurance Project Plan (Golder Associates, 1990). The table presents the relative percent difference (RPD) between duplicate samples for analyses that exhibit results greater than the sample detection limit. Although no data quality criteria exist for field duplicates, the EPA recommends that the RPD for laboratory duplicates fall within a control limit of +/-20% for water samples and +/-35% for soils when sample values are 5 times the sample detection limit. (EPA, 1988b).

~~All RPD's for the duplicate sample analysis were below the control limits for both metals and conventional parameters.~~

~~3S3 Performance Audit Samples~~

One performance audit sample was prepared as described in Section 4.4 of the Quality Assurance Project Plan (Golder Associates, 1990) and shipped to the laboratory for metals analysis. The results of the analysis are presented in Table 3-3. The sample was prepared by spiking laboratory prepared deionized water with a known concentration of target analytes. The sample analysis results submitted by the laboratory were within the EPA recommended limits of 75-125 percent recovery.

~~3.6 Data Validation~~

A total of 53 samples were analyzed by Pacific Environmental Laboratory, Inc. (PNELI), Gulf South Environmental Laboratory, Inc.(GSELI) and Southwest Laboratory of Oklahoma, Inc. (SWLO). Two samples (CPP45•05 and CPP45-06 both at 0-2 foot depth) were analyzed for Appendix VIII constituents which included volatile organics, semivolatile organics, organophosphate pestiddes, organochlorine pesticides, herbicides, metals, and conventional parameters as specified in section 4.4 of the Quality Assurance Project Plan (Golder Assodates, 1990). All sample analysis results were reviewed and validated in accordance with Section 8 of the Quality Assurance Project Plan (Golder Associates, 1990) and with the EPA functional guidelines for evaluating inorganic data and organic data (EPA 1988a and EPA 1988b). Validation performed on each sample delivery group was documented in the specified report format shown on Figures 8.1 and 8.2 in Section 8 of the Quality Assurance Projed Plan (Golder Assodates, 1990). The following sections outline the findings of the validation procedure for this site.

~~3.6.1 Holding Times~~

Holding times specified in the functional guidelines were compared to the reported dates of extraction and analysis for organic, inorganic, and conventional fractions. Volatile organic and semivolatile organic extraction and analysis were performed within the specified holding times for both soil and water matrices. Mercury analyses were completed within 28 days from time of sample collection. The holding time for pH analysis was exceeded for Case 2771 (Golder ID CPP45-04-pH/CL/S-3-2, CPP45-04-pH/C1./S-5-2, CPP45-05-pH/CL/S-3-2, and CPP45-04-pH/CL/S-1-1) by one day, however, data was acceptable for use as reported.

~~3.6.2 Instrument Calibrations~~

Instrument calibrations were checked for each fraction with no anomalies noted. Samples were analyzed within the appropriate time windows for each calibration. Organic analyses were performed within the specified time windows for tuning criteria, and both initial and continuing calibration criteria were met as specified in the USEPA Contract Laboratory Program Statement of Work (CLP/SOW)(EPA, 1990a and 1990b).

~~Golder Assoclates January 31, 1991 20 893-1195.900~~

The inorganic data had minor problems assodated with the instrument calibrations. The metals data was flagged as estimated because the matrix spike recovery limits exceeded the recovery windows specified in the CLP/SOW,(EPA, 1990b). Based on the calibration recoveries several sample results were requalified as estimated. These regulations do not affect the use of data for site characterization purposes.

~~3.6.3 Project Detection Limit Goals~~

Detection limit goals were met for volatile analysis (EPA method 8240) and semivolatile analysis (EPA method 8270) where applicable. The samples (CPP45-05 and CPP45-06, both at 0-2 foot depth) analyzed for Appendix VIII compounds were reported with an additional qualifier as to availability of the reference standard compounds and if the compound could only be identified through the use of a spectral library search.

Inorganic detection limit goals were exceeded for mercury, selenium, chloride and fluoride. The project detection limit goals for sulfate were met with the exception of Appendix VIII sample CPP45-05 where the reported detection limit is 50 mWKg. While the detection limit goals for a few of these analytes slightly exceeded the project specific goals set forth in the Quality Assurance Project Plan, the overall project detection limit goals were achieved for the site.

~~3.6.4 Quality Control Data~~

Quality control data which included matrix spike/matrix spike duplicate analysis, surrogate analysis, internal standards analysis and blank analysis were reviewed for recovery percentages. Organic quality control data was acceptable and within CLP specified limits. The sunogate percent recoveries were out of spedfication for the organophosphate pestiddes analysis, however, for this type of analysis the surrogates were difficult to analyze for and are not specified in EPA reference method.

Overall, the inorganic quality control data was acceptable. Anomalies noted in the validation process included low spike recoveries for barium, lead, and mercury with assodated data requalified as estimated.

~~3.6.5 Blank Data~~

Laboratory blank data was reviewed and compared to the sample data. Volatile organic analysis of the soils identified acetone (10 and 8 ug/L), and methylene chloride (14 and 7 ug/L) in the method blanks. Acetone and methylene chloride that were detected in the associated samples were eliminated from the sample analysis results summary (Table 4-2) in accordance with the data validation guidelines (EPA 1988a). No other target compounds or tentatively identified compounds were reported for the organic analyses.

Inorganic preparation blank values contained elemental contamination above the Instrument Detection Limit (IDL) but below the Contract Required Detection Limit (CRDL). Samples with positive results corresponding to the blank contaminants were requalified with LTJ (not detected, estimated quantitation limit).

~~4. NATURE AND EXTENT OF CONTAMINATION~~

~~4.1 Assessment of Background Data~~

Background data for metal concentrations in soils at the ICPP were obtained by the University of Utah Research Institute (UURI) during two studies conducted in 1986 and 1987. Background soils data were obtained at four locations outside the ICPP during an investigation of the Fuel Processing Restoration (FPR) Warehouse Site in 1986. According to the Quality Assurance Sampling Plan (QASP) for this study, background subsurface soils collected were to be geologically identical to soils in the FPR site sampling area. The QASP indicated the FPR site soils were to be sampled at depths of 6 inches below the pre-fill surface of the area and at 18-24 inches below the top of the first horizon samples. The actual depth interval sampled for background soils is noted in the QASP or the final report of the investigation (UURI 1986a and UURI 1986b).

In 1987, background data were obtained at three locations outside the ICPP during an investigation of the Chemical Feed and Zirconium Feed Tank Storage Areas. Samples were obtained at surface to 4 inches and at 24 inches at these locations for a total of six samples (UURI 1987a and U1JRI 1987b).

A summary of the background data obtained from the UURI investigations is provided in Table 4-1. Also shown on this table are the one-sided upper tolerance intervals (UTL) for the background data assuming a normal distribution with 95% coverage of the samples at a 95% confidence coefficient. Tolerance intervals establish a concentration range that is constructed to contain a specified proportion of coverage (P%) of the population with a specified confidence coefficient, Y (EPA 1989a).

There are potential limitations that should be considered in the use of the data obtained by UURI for determining action levels based on background concentrations. These limitations include the following:

~~• All UURI background data were obtained in the shallow surface soils (0 to 24 inches) and may not be representative of other soil types or horizons;~~

~~• Many areas of the ICPP have been graded and/or filled. Background soils sampled by UURI may not be representative of soils used for fill at the ICPP; and~~

• There may be widespread elevated concentrations of certain constituents above natural background at the ICPP from both point and non-point sources as a result of site activities. It is not appropriate to establish action levels for SWMUs based on natural background if there are widespread elevated concentrations of constituents at the ICPP unrelated to releases from the SWMUs.

~~4.2 Results of Inorganic Analysis for Solid Waste Management Unit CPP-45~~

Detected inorganic analytes of interest are presented in Table 4-2. Arsenic was detected in all boreholes ranging from 2 mg/Kg to 6.7 mg/Kg with the highest reported value in borehole CPP45-01A at the 2 to 4 foot depth. Barium was detected in each of the boreholes with the maximum value (195 mg/Kg) reported in borehole CPP45-02A at a depth of 2 to 4 feet. Cadmium was detected in surface samples from locations CPP45-05 and CPP45-06. The range of chromium was 7.2 mg/Kg to 31.4 mg/Kg and was reported above detection limits in all boreholes. Lead was detected in all boreholes with the maximum value (55.2 mg/Kg) reported in borehole CPP45-02 at the surface. One location (CPP45-01) reported mercury at the detection limit of 0.09 mg/Kg. Selenium was reported at CPP45-05 at the surface with a concentration of 0.48 mg/Kg but this has been requalified as unusable due to matrix spike data. Silver was not detected in any of the boreholes.

~~4.3 Results of Organic Analysis~~

~~There were no organic compounds detected in any of the sampling locations.~~

~~4.4 Results of General Chemistry Analysis~~

General chemistry parameters consisted of pH, soluble chloride, soluble sulfate and soluble fluoride. Soluble chloride was detected (25.1 mg/Kg) in CPP45-05 at the 0 to 2 foot depth. Sulfate levels ranged from below detection limit to 5.92 mg/Kg in CPP45-04 at the 0 to 2 foot depth. Soluble fluoride was detected in three boreholes (CPP45-01, CPP45-02, and CPP45- 06) at each of the sampling intervals. The highest concentration (310 mg/Kg) was at location CPP45-02 at the 0 to 2 foot depth. Fluoride was detected (0.500 mg/Kg) in the equipment blank at a concentration exceeding project detection limit goals, however, considerably lower than fluoride levels detected in soil samples.

~~5. HEALTH AND ENVIRONMENTAL ASSESSMENT~~

The Health and Environmental Assessment(HEA) is conducted to evaluate the impact of hazardous constituents present at a site. The HEA involves the identification of contaminants of concern, the concentrations of these constituents in the affected environmental media, and the risk to exposed or potentially exposed human or environmental receptors. The essential element of this assessment is the development of an appropriate set of health and envirorunental criteria to which the measured or predicted concentrations of toxic contaminants are compared. These criteria are primarily based on EPA-established chronic exposure limits. When the criteria are exceeded, there is a likelihood of adverse health or environmental effects and additional measures may be required to prevent or reduce these effects.

~~5.1 Identification of Toxic Contaminants~~

Analyses of soil samples from shallow boreholes at SWMU CPP-45 were conducted to detennine the presence and concentration of inorganics and organics in the soil. The inorganic analysis results are presented in Table 4-2. Six of the analytes are not included in this HEA. Arsenic, barium, cadmium, chromium, selenium, and silver did not exceed background concentrations or were analyzed for, but not detected, at the given detection limit. Two other analytes, iron and nickel, are also not evaluated further in the HEA. Iron is an essential element for humans that is generally considered non-toxic except under conditions of large, single, and accidental ingestion of medicine or in the presence of specific genetic or medical conditions. Nickel may also be essential to humans for normal growth and development. Median soil concentrations of nickel are typically 26 - 50 mg/kg (ATSDR, 1988). The highest concentration of nickel detected at SWMU-45 was 19.7 mg/kg.

Lead was detected at a concentration greater than background. Lead is a well-documented cumulative toxin that has also been shown in animal studies to produce cancer. Differences between individuals such as age, nutritional status, and other factors can influence the dose at which lead is toxic. Children, for example, are considered a sensitive population because they are particularly susceptible to neurological changes from excess lead intake. Because some of the toxic effects can occur at blood lead levels so low as to be essentially without a threshold, the EPA recommends that neither a chronic reference dose nor a numerical cancer risk be used at this time (EPA, 1991). Although the soil lead concentration of 55.2 mg/kg at SWMU-45 exceeds the background UM,this concentration is significantly less than the soil concentration of >500mg/kg determined necessary to produce an increase in blood lead levels in children exposed to lead containing soil (EPA, 1989a). Therefore, lead is not considered further in this HEA.

Mercury is present at a level slightly higher than the background UTL. This compound has a number of inorganic and organic derivatives, and toxicity is highly dependent on the form and route of exposure. Organic (alkyl) mercury compounds are generally more toxic by ingestion than inorganic (metallic) mercury. Target organs for toxic effects are the central nervous system and the kidney. Mercury has not been classified as to human carcinogenicity. Mercury is included in the HEA for SWMU-45.

~~Golder Assoclates lanuary 31, 1991 27 893-1195.900~~

Three additional parameters, sulfate, chloride, and fluoride, were also analyzed for and detected in the soils at SWMU-45. Sulfate, detected at 5.92 mWkg, and chloride, detected at 25.1 mWkg, are present in the soils at the acid storage tank vault CPP-757 site where hydrochloric and sulfuric add were stored. Sulfate toxidty is minimal and usually associated with mild gastrointestinal effects (Gosselin, et al., 1984). Chloride is considered essentially nontoxic. Normal soil concentrations of chloride range from 10 - 100 mg/kg (Dragun,1988). Sulfate and chloride, therefore, are not considered further in this HEA.

Fluoride, detected at 310 mg/kg, is present in the soil at the hydrofluoric add storage tank vault CPP-727. Fluoride toxicity is assodated with any soluble fluoride compound which dissodates to produce fluoride ion (Gosselin et.al., 1984). The type and severity of toxicity varies with the chemical form, the route of exposure, and the duration of exposure. The potential for acute toxic effects from exposure to fluoride found in the soil is minimal since fluoride interacts with the environment and the soil to form relatively stable compounds. However, chronic effects from exposure to low doses of fluoride in these forms, through ingestion or occupational exposure to fluoride-containing dusts, can produce deposition of fluoride in the teeth (dental fluorosis) and the bone (skeletal fluorosis or osteosclerosis) (Baselt and Cravey, 1989). Fluoride is not known to be carcinogenic. fluoride is included in this HEA.

~~No organic contaminants were detected during the sampling analyses for SWMU CPP-45.~~

~~5.2 Identification of Exposure Pathways~~

The two contaminants of interest detected at SWMU CPP-45, mercury and fluoride, are located in the soils at the hydrofluoric add storage tank vault CPP-727. The vault is approximately 8 ft in depth; soil samples were obtained from boreholes in the vault floor. Mercury was detected at concentrations just above background at a depth of 2 - 4 ft; the highest fluoride concentration was detected in soils at 0 - 2 ft. Thus, the contaminants 11-5 appear to be localized in the upper portion of the soil column in the vault, but Afr \tri p _e_c) approximately 8 - 12 ft below the general ground surface. See Table 4-2. 1\1-1-42-0' p,ky -c1u Soil ingestion or dermal contact with these soils on a regular basis would not occur unless! the soils are disturbed or moved to the surface outside the vault where more frequent contact would be possible. However, very limited exposures may occur for individuals working in the vault.

The depth to groundwater, the lack of surface water bodies in the vicinity of the vault, the limited areal extent of contamination, and the low concentrations of contaminants detected preclude any significant impact on water from SWMU CPP-45. Thus, water is eliminated as a potential exposure pathway.

The inhalation pathway is also inoperative unless the soils are exposed, and even then a significant adverse risk from airborne fluoride or mercury contaminated particulates is improbable given the low concentrations of contaminants detected in the soils and limited areal extent of contamination (i.e., absence of a significant source).

~~Golder Associates January 31, 1991 28 893-1195.900~~

~~5.3 Identification of Receptor Populations~~

The typical receptors for contaminants present at SWMU CPP-45 are workers with direct access to and work duties at the acid storage tank vault CPP-727. The ICPP is a secured industrial site with limited access.

~~5.4 Human Health Assessment~~

No adverse health effects can be attributed to the mercury and fluoride detected in the vault soils without direct exposure to the soil. As discussed in Section 5.2, the soils would have to be excavated or moved outside the vault where workers at the ICPP could have frequent and ongoing exposure to the contaminants through incidental soil ingestion or dermal contact, the two potentially operative exposure pathways.

For the purposes of an initial screening, it is conservatively assumed that the vault soils are accessible. Based on this assumption, the potential human health effects from the concentrations of mercury and fluoride identified at SWMU CPP-45 are assessed. The results of the assessment are summarized in Table 5-1. Both mercury and fluoride are known to have systemic toxic effects if exposures are great enough. The soil concentrations at which no systemic toxicity would be likely to occur for even a sensitive population (16 kg child, ingesting 200 mg soil per day for a 5 year exposure period) were calculated as part of the assessment. This soil concentration, if ingested, would result in an oral dose equivalent to the applicable chronic reference dose (RfD) for each contaminant. The RfD for a contaminant is the daily intake of the contaminant to which even a sensitive individual might be exposed without developing documented critical toxic effects. This screening is conducted as recommended in the RCRA Facility Investigation Guidance (EPA, 1989b).

~~The equation for calculating the soil screening criterion is given below:~~

~~CS = RfD x BW IR x CF where:~~

~~CS = Soil concentration screening aiterion RfD = Chronic Reference Dose BW = Body Weight (16 kg) IR = Ingestion Rate (200mg/day) CF = Conversion Factor (1E-06 kg/mg)~~

None of the soil concentrations detected exceed the maximum allowable soil concentrations based on the RfD (see Table 5-1). Therefore, systemic adverse health effects should not occur in even sensitive individuals exposed to soil contaminants at the levels detected in the soils at SWMU CPP-45. It should be noted that two screening criteria are provided for fluoride. An RfD of 0.06 mg/kg/day is published that reflects the level of exposure children may have without developing dental fluorosis from an excess intake of fluoride (EPA, 1991).

~~Golder Associates January 31, 1991 30 893-1195.900~~

This effect is considered a cosmetic effect rather than an adverse or toxic health effect. A second intake level based on an adverse health effect in adults (skeletal fluorosis) is also reported in the Integrated Risk Information System (EPA, 1991) and is presented in Table 5-1. The soil concentrations of fluoride found at SWMU CPP-45 do not exceed the screening criteria corresponding to either of these acceptable intake levels for fluoride.

~~Mercury and fluoride are not known to be carcinogenic substances. Therefore, no determination of carcinogenic risk from possible exposures is applicable.~~

For both contaminants, the contribution of dermal contact or inhalation exposures to the overall health risk, although not quantitatively evaluated, would be inappreciable because of the low levels of soil contamination, the lack of ongoing access to the soils, and the depth of the soil contamination.

Given the results of the screening presented above, adverse health impacts to workers in the vicinity of or with direct access to SWMU CPP-45 would not occur from the contaminant concentrations detected.

~~5.5 Environmental Assessment~~

SWMU CPP-45 is located within the controlled boundaries of the ICPP and is the site of two acid storage tank containment vaults located 6 - 8 ft below ground level. All detected soil contaminants are located in soils below the floor of these vaults. SWMU CPP-45 does not support any vegetation with roots extending into the area of detected contamination. Large animals and migratory wildlife have no access to or are not known to frequent the immediate area surrounding SWMU CPP-45. Consequently, no adverse impact on terrestrial biota should occur.

The airborne transport of mercury or fluoride located in the soils at SWMU CPP-45 cannot occur because of the depth to the contaminants and the low levels of contaminants present in the soil (i.e. absence of a significant source). Thus, environments downwind from the area will not be impacted via the air pathway.

Low annual rainfall will result in little surface runoff and infiltration. These conditions, in addition to the depth to groundwater (approximately 455 ft) and low level of soil contamination will limit migration of contaminants and any adverse effects on surface waters or groundwater in the vicinity of SWMU CPP-45. Consequently, surface water and groundwater will not be impacted by the levels of soil contamination detected at SWMU CPP-45.

~~6. SUMMARY AND CONCLUSIONS~~

This sections presents a stunmary of the results of investigations at SWMU CPP-45 containment vaults CPP-727 and CPP-757. Condusions regarding the nature and extent of contamination detected and potential health or environmental effects associated with the contaminants detected are also presented. In addition, recommendations for additional investigations or corrective measures are presented.

~~6.1 Suntmary~~

Four boreholes were hand augered and sampled to a depth of 6 feet. Three additional boreholes were hand augered and sampled to a depth of 1.5 feet and one borehole was hand augered and sampled to a depth of 4 feet but terminated at these depths due to ground conditions or underground wiring. Samples in containment vault CPP-757 were analyzed for pH, chloride, sulfate, and total metals. Samples in containment vault CPP-727 were analyzed for pH, fluoride, and total metals. One set of surface samples from each vault were also analyzed for the 40 CFR Part 261 Appendix VIII constituents.

~~Results of the sampling and analysis are summarized below:~~

~~Lead and mercury were detected at concentrations higher than the Upper Tolerance Limit (UTL).~~

~~Fluoride was detected in containment vault CPP-727.~~

~~No organic compounds were detected during the sampling analyses for containment vaults CPP-727 and CPP-757 in SWMU CPP-45.~~

~~6.2 Conclusions~~

The concentrations of the inorganics detected from tank vaults CPP-727 and CPP-757 in SWMU-45 do not pose a risk to human health or the environment and it is unlikely that permissible exposure levels (see Table 5-1) would be exceeded. No organic compounds were detected for either vault. There is no need to conduct additional investigations at these sites. Removal, decontamination, or dosure, under RCRA should not be required.
