The reporting period covered by this report is 1 March 2002 -1 September2002. Included is a work plan for passive soil gas survey for three SWMUs 625, 202, and 551. Ifyou have any questions regarding this report, please direct them to Paul Hancock at (435) 863- 3344. Sincerely Susan Jew, ^Director Environmental Services c: Don Ostler, Director, Division of Water Quahty SEMI-ANNUAL RFI PROGRESS REPORT 1 March 2002 -1 September 2002 1. Description and estimation of tlie percentage of the RCRA Facilities Investigation completed; Three potential Solid Waste Management Units within the T-75 facility were investigated. These are old test holes where thermal safety studies were conducted approximately 20-25 years ago. The holes were approximately 2- 3 feet in diameter and one foot deep. To the best of our knowledge only one test was conducted at the three sites using a then new potential oxidizer hydrazinium diperchlorate. Due to the instability ofthe material, gradual increases in temperature were tested. One ofthe tests detonated therefore fiirther tests were cancelled and the material and equipment were removed fi-om all sites. It was not believed that any waste was left or any hazardous constituents remained. To confirm this information the three test holes were sampled for constituents of concem, volatile organics, explosive constituents, and total metals. Prior to sampling, small shaped charges of pentalite were used to fire the holes to assure safety with minimal displacement ofthe soil. No indications of an additional energetic release were seen. 2. Summaries of all findings; The raw analytical data from all sampling activities during the reporting period for T-75 are included as an attachment. No hazardous constituents were detected above backgroimd levels with detection limits far below any risk-based levels. Thiokol believes that this confirms the indication that they would not be Solid Waste Management Units. 3. Summaries ofall changes made in the RCRA Facility Investigation during the reporting period; Additional investigations of three solid waste management units #625, 202, and 551 using passive soil gas surveys are proposed. The purpose ofthe survey is to determine that sources of groundwater contamination plumes. The Work Plan is included with this report. Thiokol requests approval ofthe Work Plan so that work can commence prior to freezing weather. 4. Summaries of all contact with representatives of the local community, public interest groups or State Government during the reporting period: Correspondence regarding RFI activities has been limited to the Division of Solid and Hazardous Waste, the Division of Water quality, the U.S. Fish and Wildlife and the Department of Natural Resources. 5. Summaries of aii problems or potential problems encountered during the reporting period; There were no significant problems encoimtered during the reporting period. 6. Actions taken to rectify problems Thiokol continues to review all available information and pursue all avenues to resolve any uncertainty associated with the solid waste management imits. Changes in personnel during the reporting period; There were no persormel changes. The existing environmental staff will continue to conduct the sampling when possible. Contractors will be used when specialized equipment is required. Projected work for the next reporting period; Efforts for the next reporting period will focus on investigating additional solid waste management units, primarily the passive soil gas survey and report preparation for these projects. 9. Copies of daily reports, inspection reports, laboratory and monitoring data. The raw analytical data and field notes from all sampling activities are included as an attachment.

These units have demonstrated effectiveness at other locations for determining subsurface areas impacted by VOCs and old disposal areas. 2.0 SITE LOCATIONS The passive soil gas samplers will be used at three SoHd Waste Management Units. These units are suspected of being contamination sources for VOCs currently found in the ground water at Thiokol. . i't^ -: l- 'i^^ -""'^•^ v]/' 7 :M' ^ 625 202 551 Old Septic Tank drain fields A, B, and C, located across fi-om the Space administration area. These units were sample previously as part ofthe RFI. Results indicated that no hazardous substances were above background or risk based levels. Old propellant buming ground at Plant III. This site was sampled previously as part if the RFI. No contamination above background levels was found. Recommendation of no fiirther action. Old drum storage area at building M-l87 This site was sampled previously as part ofthe RFI. Results showed trace amounts of two solvents, but far below risk based levels. Recommendation of no further action. 3.0 BACKGROUND INFORMATION Previous soil sampling at the three Solid Waste Management Units 622, 551, 202 have not indicated any significant contamination. A copy ofthe RFI for each of these units is attached in Appendix A. However, groundwater contamination pattems indicate that the source ofthe contamination may be from previous disposal practices at these sites. Thiokol is seeking to identify the sources ofthe groundwater contamination plume at these locations with the use of passive soil gas modules. ATK Thiokol Propulsion RFI Work Plans September 2002 3.1 Module Description A typical passive soil gas module consists of several passive sorbent collection devises (sorbers). A typical sorber is 15 to 25 millimeters (mm) long, with a 3 mm inside diameter (ID), and contains 40 milligrams (mg) of a granular adsorbent material. Adsorbents used are typically polymeric and carbonaceous resins chosen for their affinity for a broad range of VOCs and SVOCs with minimal uptake of water vapor. The units have a retrieval cord which is fashioned with a loop. Both the rettieval cord and sorbant container are constructed solely ofa chemically inert, hydrophobic, microporous membrane (expanded polytetrafluoroethylene, ePTFE). The loop is used as a means of tying the module to a string for installation and retrieval. Attachment 1 shows a typical module. VOC and SVOC vapors penetrate the module freely and collect on the adsorbent material. 3.2 Use and Limitations of Data Data from the Passive soil gas modules generally are intended to indicate potential site contamination. Data from the passive soil gas modules are of definitive quahty. They are considered to provide definitive evidence ofthe presence or absence of contamination. Passive soil gas module data identify soil gas mass levels present in the vapor phase. Vapors are subject to a variety of attenuation factors during migration away from the source and concentration in the module. Thus, mass levels reported from the module will often be less than concenfrations reported in soil and groundwater matrix data. (Passive soil gas module data are not reported in concentration units: they are reported in mass units.) The long time frame for Passive soil gas module sampling should allow an equilibrium measurement of soil gas concentrations and provides fiilly acceptable sensitivity based upon EPA demonsfration project results. In most instances, the Passive soil gas module soil gas masses reported on the modules correlate favorably with concentrations reported in the soil, active soil gas or groundwater (e.g., where soil gas levels are reported at greater levels relative to other sampled locations on the site, matrix data should reveal the same pattem, and vice versa). However, due to a variety of factors, a perfect comparison between matrix data and soil gas levels can rarely be achieved. Soil gas signals reported by this method cannot be directly attributed to soil-adsorbed, groundwater, and/or free-product contamination. The soil gas signal reported from each module can evolve from all of these sources. Differentiation between soil and groundwater contamination can only be achieved with prior knowledge of the site history (i.e., the site is known to have groundwater contamination only). ATK Thiokol Propulsion RFI Work Plans September 2002 4.0 SAMPLING STRATEGY 4.1 Sampling Protocol Approximately 100 samples will be collected using Passive soil gas module cartridges. 48 will be collected at the old drain fields (SWMU 625), 25 at the old propellant bum ground (SWMU 202) and 24 at the old dmm storage area (SWMU 551). Grids will be measured and each site and passive soil gas module cartridges will be installed at each grid intersect. Drawings ofthe sites with the grid layout are in Attachment 2. The sorber module consists of a porous tube, which is sealed at one end. Contained in the tube is the granular sorbent with a unique identification tag for each sample. The sorber module will be placed at the locations described above to a depth of not less than 2 feet using the procedures described in section 6 . The module will remain in place approximately 2 weeks , allowing sufficient time for potential contaminants to diffuse into the sorbent material. Modules are then collected by field personnel, put into specially prepared impermeable containers and shipped under strict chain of custody to the laboratory. The analysis ofthe modules requires the technology ofthe associated laboratory for the best results. The list of analytes is a modified short list of SW-846 Method 8260 volatile compounds. 4.2 QA/QC Samples / Data Quality Objectives The current laboratory limits are presence or absence of the compounds rather than a defined limit (see section 8 ofthis document for those laboratory limits). Approximately 5% field duplicates will be collected for the Passive soil gas module sampling. The Passive soil gas module field duplicates will be collected simultaneous with the original sample. Passive soil gas module duplicates are inherent in the module set-up. Two sorbers are contained in each module or two single modules will be placed in the same bore hole. The field personnel will designate the samples to be used as the field duplicate pair so that second analysis will be performed. Duplicate precision is independent ofthe bias (accuracy) ofthe analyses and reflects only the degree to which the measurements agree with one another, not the degree to which they agree with the "true" value ofthe parameter measured. The precision ofthe Passive soil gas module analysis will be determined from the modules matrix duplicates. The data validation will use less than 50% RPD limit expressed as follows: Where: RPD = relative Xl, X2 = value of X,-X2 RPD = (100%) (X!+X2)/2 percent diflference sample 1 and sample 2 Approximately 5% trip blanks will be collected for the Passive soil gas module soil gas samphng. This corresponds to an uninstalled module taken to the field but not placed in the soil. ATK Thiokol Propulsion RFI Work Plans September 2002 For the Passive soil gas module, frip blank modules will be provided to document potential exposures that were not part ofthe soil gas signal of interest (i.e., impact during modules shipment, installation and retrieval, and storage). The trip blanks are identically manufactured and packaged soil gas modules to those modules placed in the subsurface. However, the trip blanks remain unopened during all phases ofthe soil gas survey. Levels reported on the trip blanks may indicate potential impact to modules other than the contaminant source of interest. Due to the nature ofthe soil gas modules to be collected, analysis of MSs and MSDs is not possible for this project. The current laboratory limits are presence or absence ofthe compounds rather than a defined limit. The results ofthe blank analysis will help to define accuracy under these limits. 4.3 Background Samples Three background samples will be collected in areas known or believed to be free of contamination within the Manufacturing and Administration Area for use in comparing concentrations Extensive soil sampling ofthe Thiokol facility has established a data base for naturally occurring organic constituents. This data base consists of background samples used in the closure of various RCRA facilities at Thiokol. 5.0 LIST OF FIELD EQUIPMENT The following table lists all parts and equipment that will be used for this investigation: Description Shipping boxes containing individually numbered passive soil gas collectors (Modules), including trip blanks Stainless steel insertion rod, in threaded sections (for placement of modules in pre- drilled/driven pilot holes) Corks with screw eyes attached Chain of Custody and Installation/Retrieval Log Equipment to lay out and mark sample locations (scaled map, measuring tapes, pin flags, spray paint) Disposable gloves and equipment decontamination supplies "Little Beaver" gas powered sampling auger 2-inch diameter stem up to 36 inches long extensions Tamper-evident seals Packing Tape ATK Thiokol Propulsion RFI Work Plans September 2002 6.0 MODULE INSTALLATION TECHNIQUE Passive soil gas module modules will be installed according to the manufacturers specifications given below. All ofthe Passive soil gas module modules will be installed to not less than 2 feet sampling depth and left in place for two weeks or as recommended by the manufacturer prior to module retrieval. Passive soil gas module installation protocol is given below: • Always obtain utility clearance before digging or probing. • It is not recommend installation of modules be within 15 feet of monitoring wells, utility trenches or other conduits, which may act as a preferential pathway for soil vapor migration. • Drive/drill narrow pilot hole at desired pre-market location • Wearing clean gloves, remove module from numbered container and re-seal the jar (this numbered container should correspond to the numbered module ID tag-please verify this) • Measure and cut a section of cord that is suitable for the installation. • Tie one end ofthe cord to the loop in the module, and tie the other end ofthe cord to the screw-eye in the appropriate size cork • Place insertion rod into the pre-cut pocket at the base ofthe module and lower it into the hole. Ifyou encounter resistance remove the module and ream the hole and re-insert the module • Once deployed to the desired depth, press the insertion rod against the side or the hole and twist slightly to release the module. Remove the rod and push any excess cord into the pilot hole and plug it with the cork. • Indicate the module number, date, and time of installation and any pertinent comments on the installation/retrieval log. Write the module serial number on the site map adjacent to the appropriate map location. • Clean the tile probe or drill bit and the insertion rod prior to use at the next location. Replace the gloves as necessary before handling any modules • Following module installation, the modules selected as trip blanks should be kept in the sample box provided and stored as described above in "STORAGE" until sample retrieval. Passive Soil Gas Module Retrieval • Following the module exposure period (two weeks or as recommended by the manufacmrer) identify and check each module location in the field using the site map. • Remove the cork with a penknife or cork screw. Grasp the cord and pull the module from the ground; verify the module ID number. Cut off and discard the cork and cord. Place the entire module in its labeled container and tightiy secure the lid. • Replace the sample container in the box. ATK Thiokol Propulsion RFI Work Plans September 2002 6.1 Passive soil gas module Modules shipping • Replace the sample container in the box. Where possible, please attempt to keep modules in numbered sequence to expedite sample check-in and processing. • Complete the module retrieval date/time on the installation/retrieval log • Do not use Styrofoam "peanuts" as packing material. Bubble packing is acceptable. Water ice can be added if desired, but cooling in general is not necessary. If shipping with ice, please take precautions to keep boxes dry (perhaps shipping in a cooler) • Retum the samples with paperwork (preferably by ovemight courier). Holding time is 7 days from collection ofthe passive soil gas module to date of analysis. No special preservation is required, but it is recommended that samples not be subjected to extremes of temperature or pressure. If ice is added to the shipping container, care must be taken that no precipitation enters the modules. 6.2 Passive Soil Gas Module Storage Passive soil gas module modules are specially cleaned and stored after manufacturing. They must remain sealed in their vials in the shipping boxes until deployment. DO NOT store them near potential sources of organic vapors, including petroleum fuels, fiiel exhaust, solvents, or in areas of new constmction or remodeling where paints, adhesives, foam insulating materials, etc. may be present. 7.0 SAMPLE DOCUMENTATION The following information must be recorded in the Field Book: Date and time of sampling Sampler's name and signature Location of samples including depth and corresponding module ID number Tjqje, number, sample number, and seals used on sample bottles Weather Any other pertinent information ATK Thiokol Propulsion RFI Work Plans September 2002 8.0 ANALYTICAL PARAMETERS The Passive soil gas module modules are required to be analyzed by the manufacturer at their laboratory oi other approved laboratory. The laboratory uses modified EPA SW-846 Method 8260 for volatile organic compounds. The sensitivity ofthe Passive soil gas modules for COCs is expected to be quite high. Metho Detection Limits for Method 8260 analysis in the typical laboratory are as follows: COC and Typical MDL for Soil Gas Modules Compound 1,1,1,2-Tetrachloroethane 1,1,1-Trichloroethane 1,1,2,2-Tetrachloroethane 1,1,2-Trichloroethane 1,1-Dichloroethane 1,1-Dichloroethene 1,2,4-Trimethylbenzene 1,2-Dichloroben2ene 1,2-Dichloroethane 1,3,5-Trimethylbenzene 1,3-Dichloroben2ene 1,4-Dichlorobenzene 2-Methylnaphthaiene Acenaphthene Acenaphthylene Benzene Carbon tetrachloride Chlorobenzene Chloroform cis-1,2-Dichloroethene Ethylbenzene Fluorene m/p-Xylene Methyl-tert-butylether Naphthalene Octane o-Xylene Pentadecane Tetrachloroethene Toluene trans-1,2-Dichloroethene Trichloroethene Tridecane Undecane Vinyl Chloride Abbreviation 1112TetCA 111TCA 1122TetCA 112TCA 11 DCA 11 DCE 124TMB 12DCB 12 DCA 135TMB 13DCB 14DCB 2MeNAPH Acenaphthene Acenaphthylene BENZ CCL4 CIBENZ CHCL3 C12DCE ETBENZ Fluorene mpXYL MTBE NAPH OCT oXYL PENTADEC PCE TOL t12DCE TCE TRIDEC UNDEC VC MDL. ua 0.02 0.03 0.02 0.07 0.02 0.06 0.02 0.02 0.01 0.02 0.05 0.02 0.02 0.01 0.01 0.03 0.03 0.01 0.02 0.02 0.02 0.02 0.02 0.48 0.02 0.10 0.02 0.02 0.03 0.03 0.08 0.03 0.02 0.03 0.08 ATK Thiokol Propulsion RFI Work Plans September 2002 9.0 SAMPLE ACCOUNTABILITY AND CUSTODY Follow procedures specified in the in the Data Collection Quality Assurance Plan in Volume Two o the RFI Work plams.

This unit was operated for a short period of time for the disposal of test and off-specification propellants by open buming. The burninig area Is contained within a fenced area measuring approximately 25 ft by 25 ft. tt is estimated that only about 200 to 300 pounds of waste were burned during the period of operation. Physical Setting The High-Performance Propellant Development Area is comprised of soils consisting of a clayey, silt unit interbedded with minor sand and fine gravel. The thickness of the silt unit is greater than 20 feet. The gravels are derived from limestone strata of the Pennsylvanian Oquirrh Formation. The gravels consist of medium to dark gray angular to subangular clasts of limestone and dolomitic limestone. The silt is calcareous with some clay, sand, and gravel. Clays of the upper interval tend to swell. The depth to ground water in the vbinity is estimated to be 300 feet. The ground water, based upon the available data, appears to be restricted to movement along faults and fractures. This is evidenced by Plant Well No. 3, which was drilled 325 feet into unfractured matenal and was abandoned, as it produced only a small volume of water. Subsequently, Plant Well No. 3A was drilled as a replacement to Plant Well No. 3, and was drilled on a fault having a N85 W trend. This well can produce 190 gpm with five feet of drawdown. The movement and location of ground water beneath the area known as the High-Perfonmance Propellant Devek)pment Area has not been well defined. Two wells, TCC3 and TCC3A, were drilled in this area in 1956 and 1962. Detailed discussion on these two wells can be found in RCRA Compliance Plan prepared for Thiokol by Underground Resource Management, Inc., in August 1985. Well TCC3 was drilled 350 feet t}elow ground surface and encountered ground water at approximately 300 and 320 feet; static water levels measured in 1962 showed the water at an elevation of 4260 feet. This well was later abandoned and has not been used. Well TCC3A is currently being used to supply process water to buildings in the High-Performance Propellant Development Area. When drilled, this well encountered water at a depth of 317 feet and at 395 feet. The surface elevation of the ground water in 1962 was 285 feet. Two more wells have been drilled near the M-225 buming grounds. One of these wells was drilled to a depth of 200 feet, but could not be completed because the fractures in the limestone formations prohibited further drilling. A second well was completed and ground water encountered at 618 feet. Ground water appears to flow south and southeast toward the Great Salt Lake Waste Characteristics The wastes managed at this site consisted of waste propellant and propellant-contaminated waste. Thiokol Propulsion RCRA Facility Investigation Cl Figure 202-2 % Contamination Characterization Table 202-1 is a summary of the constituents detected in at least one sample during the investigation for this site. This table also shows the range of concentrations for each constituent. Minimum concentration values preceded by a less-than sign (<) indicate the laboratory reported the chemtoal was not detected and the value shown represents the detection limit. If the laboratory reported a metal undetected in a sample, but that metal was detected in other samples, the minimum concentration shown is one-half the reported detection limit. Also included on Table 202-1 is the 95 percent upper confidence limit (UCLgg). The UCL95 is a value calculated from the reported laboratory data and represents the value that is equal to or exceeds the true mean concentration of a chemical at the investigation site. Use of this value as the concentration term when comparing to background and risk-based screening levels provides reasonable confkJence that the true site exposure will not be underestimated.

Because of the qualified data and the very low concentrations, the results were not considered as positive, and these organics were eliminated from further consideration. No other organics were detected in any of the samples. No nitroglycerine, HMX, silver, or mercury were detected in any of the samples from this site above the method reporting limits. ^ Comparison to Background Concentrations Table 202-2 is a summary of the corresponding background concentrations for those constituents detected and summarized in Table 202-1. Included are both the results of background samples taken from areas at Thiokol believed to be representative of naturally occurring levels of chemicals in the soil and background concentrations of elements is soils which have been collected in soils of the counterminous U.S. and analyzed by the U.

The storage area was designated as M-187 located in Thiokol's Administration and Manufacturing Area (See Figures 551-1 and 551-2). The site was used as storage for empty drums to be returned back to vendors or non-returnable drums to be sold to drum recyclers or otherwise disposed. The operational dates for this site are unknown. However, its use is estimated to have begun approximately 10 to 15 years prior to when the drum storage yard was moved to M-136, which occurred in 1986. This site was not intended for management of waste materials. The empty drums likely contained some residual product as evidence of spilled materials is visible on the surface of the soil. Physical Setting This site is located on the western flank of the Blue Springs Hills. This is a horst and graben block fault system with two major fault trends: north 15 degrees east and east-west. The Blue Springs Hills at this location consists of Paleozoic carbonate units covered with a thin veneer of Quaternary alluvium. The valley is filled with Tertiary and Quaternary sediments which include older fluvial and lacustrine sediments, alluvial fan deposits. Lake Bonneville sediments, and recent alluvium. M-187 is sited on the gentle slope of a moderately large alluvial fan. Sediments consist of unconsolidated gravels, sands, and clays of colluvial (debris flow), fluvial, and alluvial depositional environments. Within the valley-fill, ground water occurs in unconfined conditions. The valley-fill sediments consist of sands and gravels interbedded with silts and clays. Generally, the coarser materials are found along the margins of the valley and as basal sediments above the bedrock. The silts and clays act as confining units interbedded within the coarser materials. Within consolidated sediments, ground water occurs in fault zones and solution cavities in the limestones. The regional aquifer is found in unconsolidated alluvial material within the Blue Springs Valley and in fractured bedrock along the flanks of the range. There does not appear to be a distinct low permeability barrier t)eneath the entire site, although discontinuous zones are ubiquitous. The thickness of the aquifer is unknown but it is expected to be greater than 500 feet. All of the wells installed to date have been drilled to less than the bottom of the aquifer. The deepest wells drilled into the saturated zone are Thiokol exploratory water wells TCC8 and TCC8A, completed in 1960 and 1962, west of UDLV. Well TCC8A was drilled 610 feet deep, penetrating 460 feet of saturated material. This site is located approximately 800 feet north of monitoring well B-5 and approximately 1000 feet southwest of well B-4. Wells B-4 and B-5 were installed in 1989 to a depth of 237 feet and 176 feet respectively. The depth to ground water was 215.87 feet in well B-4 and 153.48 feet in well B-5 when measured in November 1999. Ground water movement appears to be from well B-4 towards well B-5 which is a southwesteriy direction. Thiokol Propulsion RCRA Facility Investigation m g^jj^i:i*- ^.v' Figure 551-2 Contamination Characterization Table 551-1 is a summary of the constituents detected in at least one sample during the investigation for this site. This table also shows the range of concentrations for each constituent. Minimum concentration values preceded by a less-than sign (<) indicate the laboratory reported the chemical was not detected and the value shown represents the detection limit. If the laboratory reported a metal undetected in a sample, but that metal was detected in other samples, the minimum concentration shown is one-half the reported detection limit. Also included on Table 551-1 is the 95 percent upper confidence limit (UCL95). The UCL95 is a value calculated from the reported laboratory data and represents the value that is equal to or exceeds the true mean concentration of a chemical at the investigation site. Use of this value as the concentration term when comparing to background and risk-based screening levels provides reasonable confidence that the true site exposure will not be underestimated.

The results for many of these chemicals were also qualified as being found in the laboratory blank. Because of these data qualifiers and the very low concentrations, the results were not considered as positive results and these organics were eliminated from further consideration. The samples were also analyzed for perchlorate, but the laboratory reported the result for all samples as undetected.

The drainfield is located southwest of the rocket display across State Highway 83. Drainfield A was used during the period of 1975 -1995, drainfield B from 1982 -1995, and drainfield C from 1987 -1995. In 1995, the drainfields were abandoned when septic and industrial wastes were collected and piped to a new wastewater treatment plant. Hydrogeologic Characteristics This site is located on the western flank of the Blue Springs Hills. This is a horst and graben block fault system with two major fault trends: north 15 degrees east and east-west. The Blue Springs Hills at this location consists of Paleozoic carbonate units covered with a thin veneer of Quaternary alluvium. The valley is filled with Tertiary and Quatemary sediments which include older fluvial and lacustrine sediments, alluvial fan deposits. Lake Bonneville sediments, and recent alluvium. The disposal area is sited on the gentle slope of a moderately large alluvial fan. Sediments consist of unconsolidated gravels, sands, and clays of colluvial (debris flow), fluvial, and alluvial depositional environments. Within the valley-fill, ground water occurs in unconfined conditions. The valley-fill sediments consist of sands and gravels interbedded with silts and clays.

The deepest wells drilled Into the saturated zone are Thiokol exploratory water wells TCC8 and TCC8A, completed in 1960 and 1962, west of UDLV. Well TCC8A was drilled 610 feet deep, penetrating 460 feet of saturated material. This site is located approximately 800 feet south of monitoring well E-2,1000 feet east of well G-1, and 200 feet west of wells E-7, F-5, and B-6. Depth to ground water on June 30, 1999, was measured as 100.58' in E-2, 83.56' in G-1, and 98.80' in B-6. Ground water movement appears to be from north to south at this site. Waste Characteristics The wastes managed at this unit were predominantly domestic waste with some industrial wastewater. Thiokol Propulsion RCRA Facility Investigation Ii Figure 625-2 -• M Also included on Table 625-1 is the 95 percent upper confidence limit (UCL gg). The UCL gg is a value calculated from the reported laboratory data and represents the value that is equal to or exceeds the true mean concentration of a chemical at the investigation site 95 percent of the time. Use of this value as the concentration term when comparing to background and risk-based screening levels provides reasonable confidence that the true site exposure will not be underestimated.

Preliminary Remediation Goals. RCRA Corrective Action Levels, and EPA Soil Screening Levels. The PRG values shown in Table 625-3 are chemical concentrations that correspond to fixed levels of risk (i.e., either a one-in-one-million [10*] cancer risk, or a noncarcinogenic hazard quotient of 1). The RCRA Corrective Action Levels represent proposed values which, if found in the environment in excess of this level, could trigger the need for further analysis. Soil Screening Levels (SSL) are concentrations of contaminants in soil that are designed to be protective of exposures in a residential setting. The SSL represent the concentration of a contaminant, which if present at a site at or below this concentration, would be considered protective of ground water. The values shown were developed using a dilution attenuation factor (DAF) of 20 to account for natural processes that reduce contaminant concentrations In the subsurface. There were no cases where either the maximum area of concem concentration or the calculated UCL ^ value exceeded the risk-based concentrations. Qppglusipns The investigation conducted at this site does not indicate the presence of chemicals which are significantly atjove Thiokol background levels or which exceed risk-beised standards. This site does not appear to pose any risk to human health or the environment. Recommendations for Additional Work Based on the findings of the investigation conducted during the RFI, Thiokol believes no further action is needed for this site. m Thiokol Propulskjn RCRA Facility Investigation # # TABLE 625-3 COMPARISON TO BACKGROUND AND RISK- BASED CONCENTRATIONS CONSTITUENT Total Chromium (1:6 ratio CrVI:Cr III) Zinc UCL„ 17.91 57.43 MAXIMUM REPORTED RFI CONCENTRATIONS (mg/Kg) AREA OF CONCERN 52.90 149.00 THIOKOL BACKGROUND 38.60 89.00 USGS NATIONAL BACKGROUND RANGE' (mg/Kg) 1.0-2000 <5 - 2900 PRELIMINARY REMEDIATION' GOALS mg/Kg) RESIDENTIAL 210.68 23463.19 INDUSTRIAL 448.32 RCRA CORRECTIVE ACTION LEVELS' (ppmw) 400.00 EPA SOIL SCREENING LEVELS DAF 20 (mg/Kg) 38.00 12000.00 ' EPA Region 9 Preliminary Remediation Goals (11/1/1999) ^ EPA proposed RCRA Corrective Action Rule (55 FR 30798, July 27,1990) ^ EPA Region III Risk-Based Concentrations (October 22,1997) * USGS Background Concentrations of Elements in Soils (1984) Thiokol Propulsion RCRA Facility Investigation Depend.: VAR2 Group 1 Group 2 Code 1 2 Valid N 38 31 Sum of Ranks 1554.000 861.000 data file: 625stat.STA [ 761 cases with 6 variables ] CASE SELECTION CONDITIONS: Include if: v1='lead' VARIABLES: 5: VAR5 2: VAR2 -9999 -9999 STAT.

B Gas Chromatography and Mass Spectral Data Flag. This flag is used when an analyte is found in the blanl< as well as the sample J Gas Chromatography and Mass Spectral Data Flag. Indicates an estimated value. This flag is used either when estimating a concentration for tentatively identified compounds or when the data indicated the presence of a compound that meets the identification criteria but the result is less than the EQL (e.g. 3 J with an EQL of 10) MDL Method Detection Limit: The minimum concentration of a substance that can be confidently measured and reported. The laboratory has demonstrated that the MDL can be achieved in a laboratory reagent blank, but does not guarentee it can be achieved in ail sample matrices. The MDL is approximateiy three times the signal noise levei. EQL Estimated Quantitation Limit: The EQL generally is 5 to 10 times the MDL. For many analytes the EQL is selected as the value of the lowest standard in the calibration curve. Dil. Factor Dilution Factor: The prepared smple was diluted by this factor because the sample was too concentrated or due to other interferences in the sample matrix. Any dilution factor causes an appropriate increase in the MDL and EQL. Page 11 of 11
