Description and estimation of the percentage of the RCRA Facilitie.s Investigation completed Investigation of Potential Source Areas at Plant 3 ll is believed ihal the source of conlamination in ihe groundwater al Planl 3 is related to a source area al ihis location. In an effort lo locate a source area al Planl 3, passive soil gas samples were collected in two bisecting transects through the main facility. The samples were collecled according lo ihe DSHW approved plan used in ihe other passive soil gas investigations at the Promonlory facility. Pilot test for Treatment of Perchlorate Contaminated Soils. As descnbed in the September 2005 RFI semiannual report, a peirhlorate in soil liealinenl pilot lest was started. This soil was the result of the cleanup of perchlorate spills including SWMU 677. The DSHW approved the lest plan entitled Work Plan For a Corrective-Measure Pilot Tesl to Evaluate Ex-Situ Remediation of Pcrchlorale-Conlaminaled Soil, September 2005. Apparently, due the late season start, the bio-piles have remained cold and have not shown any biological aclion. We anticipate that the warmer weather will activate the piles. 2. Summaries of all findings Findings and tesl results from the soil gas investigation are included as an attachment (o this submiltaJ. In summary, on a relative scale, higher soil gas levels were found near the M-212 building. This was compared lo the RFI report (submitted lo the DSHW in October 2000) for this sile. The highest levels or source correlated lo the location of SWMU 149, the old sump location at M-212. Soil samples collected during the RFI investigation al this site showed low |)pb levels of TCE but nol significantly high lo warrant further investigation or remediation. A copy oi'the SWMU 149 RFI report is included as an attachment. Results from the perchlorate contaminated soil treatment will be submitted following the summer weather and the activation of the piles. 3. Summaries of all changes made in the RCRA Facility Investigation during the reporting period The implementation of the perchlorate contaminated soil Irealmcnl pilot test. 4. Summaries of all contact with representatives of the local community, public interest groups or State Government during the reporting period Coirespondence regarding RFI activities has been limited lo the Division o\' Solid and Hazardous Waste and the Division of Water qualily. 5. Summaries of all problems or potential problems encountered during the reporting period There were no significani problems encountered during the reporiing period. 6. Actions taken to rectify problems Thiokol continues to review all available information and pursue all avenues lo resolve any uncertainly associated with the solid waste management units. 7. Changes in personnel during the reporting period There are no changes in personnel. The existing environmental staff will continue to conduct the sampling when possible. Contractors will be used when specialized equipment is required. 8. Projected work for the next reporting period Efforts for the next reporiing period will focus on receiving approval for voluntary coirective measures, investigating additional solid waste management units, and report preparation. The results of the soil gas work, al this time have nol shown possible source areas. Additional sites may be surveyed wilh this melhod as warranted. The perchlorate coniaminaied soil bio-remedialion pilot lest will be ongoing through the nexl reporiing period. 9.

BEACON Report No. EM1834 PASSIVE SOIL-GAS SURVEY ATK THIOKOL PROPULSION CORINNE, UT Prepared for Ailiant Techsystems, Inc. Building M-3 Receiving 9160 North Highway 83 Corinne, UT 84307 by ENVIRONMENTAL SERVICES, INC. Beacon Environmental Services, Inc. 323 Williams Street Suite D Bel Air, MD 21014 November 11, 2005 Applying Results from Soil-Gas Surveys The utility of soil-gas surveys is directly proportional to their accuracy in reflecting and representing changes in the subsurface concentrations of source compounds. Passive soil-gas survey results are the mass collected from the vapor-phase emanating from the source. The vapor-phase is merely a fractional trace of the source, so, as a matter of convenience, the units used in reporting detection values from passive soil-gas surveys are smaller than those employed for source-compound concentradons. The critical fact is that, whatever the relative concentrations of source and associated soil gas, best results are realized when the ratio of soil-gas measurements to actual subsurface concentrations remains as close to constant as the real world permits. It is the reliability and consistency of this ratio, not the particular units of mass (e.g., nanograms) that determine usefulness. Thus, BEACON emphasizes the necessity of conducting — al minimum — follow- on intrusive sampling at one or two points that show relatively high soil-gas measurements to obtain corresponding concentrations of soil and groundwater contaminants. These correspondent values furnish the basis for approximating the required ratio. Once that ratio is established, it can be used in conjunction with the soil-gas measurements (regardless of the units adopted) to estimate subsurface contaminant concentrations across the survey field. It is important to keep in mind, however, that specific conditions at individual sample points, including soil porosity and permeability, depth to contamination, and perched ground water, can have significant impact on soil-gas measurements at those locations. When passive soil-gas surveys are handled in this way, the data provide information that can yield substantial savings in drilling costs and in time. They furnish, among other things, a checklist of compounds expected at each survey location and help to determine how and where drilling budgets can most effectively be spent. BEACON Report Number: EM1834 Passive Soil-Gas Survey ATK Thiokol Propulsion Corinne, UT This Passive Soil-Gas Survey Report has been prepared for Ailiant Techsystems, Inc. (ATK) by Beacon Environmental Services, inc. (BEACON) in accordance with the terms of Purchase Order No. ATK- 12992, dated September 16, 2005. BEACON's principal technical contact at ATK for this project has been Mr. John Holladay. 1. Objectives Soil-gaS samples were collected to determine the presence, identity, and relative strength of targeted contaminants in soil and/or ground water at the ATK Thiokol Propulsion site. Survey results will be used to identify source areas and delineate the lateral extent of contamination. 2. Target Compounds This survey targeted the 15 compounds listed in Table 1, which supplies the resulting laboratory data in nanograms (ng) of specific compound per cartridge. 3. Survey Description No. of Field Samples: 51 No. of Trip Blanks: _1 Total No. of Samples: 53 Field sample locations are shown on Figure 1. Note: No location information was provided to BEACON for sample location FBI; therefore, it is not shown on Figure 1. 4. Field Work ATK was provided a Field Kit with the equipment needed to conduct a 51-point passive soil-gas survey. Samplers were deployed on October 19, 2005, and were retrieved on November 2, 2005. Attachment 1 describes the field procedures used. Individual deployment and retrieval times will be found in the Field Deployment Report (Attachment 2). /• <^ PT340 /A PT3 39 o •> ^<$> ,/c^^ 323 Williams Street, Suite D, Bel Air, MD, 800-878-5510 Beacon Project No. E1VI1834, November 2005 / -// PT3 3flA PT3^A PT3 28 PT32tiL^ PT3 26A PT3 25 A PT3irA. ;PT?1>A^ TCC3 PT318• PT3ll^ PT3 20 TCC3A A PASSIVE SOIL-GAS SAMPLE LOCATION PT3 08 Figure 1 Passive Soil-Gas Survey Sample Locations ATK Thiokol Propulsion Corinne, UT BEACON ENVIRONMENTAL SERVICES, INC.

Adsorbent cartridges from the passive samplers were thermally desorbed, then analyzed using gas chromatography/mass spectrometry (GC/MS) equipment, in accordance with EPA Method 8260B (Modified), as described in Attachment 3. BEACON's laboratoiy analyzed each cartridge for the targeted compounds; analyses were completed on November 4, 2005. Following a laboratory review, results were provided to ATK on November 8, 2005. 6. Report Notes and Quality Assurance/Quality Control Factors Table 1 provides survey results in nanograms per cartridge by sample-point number and compound name. The quantitation levels represent values above which quantitative laboratory results can be achieved within specified limits of precision and with a high degree of confidence. The quantitation level for each compound, therefore, provides a reliable basis for comparing the relative strength of any detection of that compound. Data Compatibility. It is important to note that when sample locations are covered with or near the edge of an artificial surface (e.g., asphalt or concrete), sample measurements are often distorted (increased) significantly. Such distortion can be attributed to the fact that gas rising from sources beneath impermeable caps tends to reach equilibrium underneath the cap. Thus, a reading taken below or near an impermeable surface is much higher than it would be in the absence of such a cap. The Chain-of-Custody form, which was shipped with the samples for this survey, is supplied as Attachment 4. Laboratory QA/QC procedures included standards, surrogates, and blanks appropriate to EPA Method 8260 (Modified). Field work, analyses, and reporting were done in accordance with BEACON's Quality Assurance Program Plan. QA/QC Contaminant Corrections. Following EPA guidelines, laboratory data is not con-ected for method blank or trip blank sample contamination values; any containinadon detected on QA/QC samples is reported in Table 1. Laboratory method blanks are run each day with project samples to identify contamination present in the laboratory. If contamination is detected on a method blank, measuremenls of identical compounds on samples analyzed the same day are considered to be suspect and are flagged in the laboratory report. The laboratory method blanks analyzed in connection with the present samples revealed no contamination. BEACON ENVIRONMENTAL SERVICES, INC. Passive Soil-Gas Survey ATK Thiokol Propulsion Corinne, UT The trip blank is a sampling cartridge prepared, transported, and analyzed with other samples but intentionally not exposed. Any target compounds identified on the trip blanks are reported in the laboratory data. The analyses of the trip blanks (labeled Trip-1 and Trip-2 in Table 1) reported none of the targeted compounds, indicating that the survey site itself is the source of detected contamination. Survey findings are relative exclusively to this project and should not routinely be compared with results of other BEACON Surveys. To establish a relationship between reported soil-gas nieasurenients and acltial subsurface contaminant concentrations, which will indicate Ihose detections representing significani siibsutface contamination, BEACON recommends the guidelines on the inside front cover ofthis report.

Modifications can be and are incorporated from time to time in response to individual project requirements. In all instances, BEACON adheres to EPA-approved Quality Assurance and Quality Control practices. A. Field personnel cairy systein components and support equipmeni lo the site and deploy the passive samplers in a prearranged survey pattern. A passive sampler consists of a glass vial containing hydrophobic adsorbent cartridges with a length of wire attached to the vial for retrieval. Although samplers require only one person for emplacement and retrieval, the specific number of field personnel required depends upon the scope and schedule of the project. Each Sampler emplacement generally takes less than two minutes. B. At each survey point a field technician clears vegetation as needed and, using a slide hammer with a V-L' diameter probe or a hanuner drill with a V2' diameter bit, creates a hole three-feet deep. The technician then uses a hanuner and a %" diameter pointed metal slake to widen the top four inches of the hole. [Note: For locations covered with asphalt, concrete, or gravel surfacing, the field technician first drills a 1"- to lV2"-diameter hole through the surfacing to the soils beneath and the hole is sleeved with a %" i.d. metal sleeve.] C. The technician then removes the solid plastic cap from a sampler and replaces it with a Sampling Cap (a plastic cap with a hole covered by screen meshing). The technician inserts the sampler, with the Sampling Cap end facing down, into the hole (see attached figure). The sampler is then covered with either local soils for uncapped locations or, for capped locations, aluminum foil and a concrete patch. The sampler's location, time and date of emplacement, and other relevant information are recorded on the Field Deployment Form. D. One or more trip blanks are included as part of the quality-control procedures. E. Once all the samplers have been deployed, field personnel schedule sampler recovery and depart, taking all other equipment and materials with them. F. Field personnel retrieve the samplers at the end of the exposure period. At each location, a field technician withdraws the sampler from its hole, removes the retrieval wire, and wipes the outside of the vial clean using gauze cloth; following removal of the Sampling Cap, the threads of the vial are also cleaned. A solid plastic cap is screwed onto the vial and the sample location number is written on the label. The technician then records sample-point location, date, time, etc. on the Field Deployment Form. G. Sampling holes are refilled with soil, sand, or other suitable material. If samplers have been installed through asphalt or concrete, the hole is filled to grade with a plug of cold patch or cement. H. Following retrieval, field personnel ship or carry the passive samplers to BEACON's laboratory.

(OOJJtiil Page :^ Q{^-3_ Attachment 3 LABORATORY PROCEDURES FOR PASSIVE SOIL-GAS SAMPLES Following are laboratory procedures used with BEACON Passive Soil-Gas Surveys, a screening technology for expedited sile investigation. After exposure, adsorbent cartridges from the passive samplers are analyzed using U.S. EPA Method 8260B as described in the Solid Waste Manual (SW-846), a capillary gas chromatographic/mass spectrometric method, modified to accommodate high temperature thermal desoiplion ofthe adsorbent cattridges. This procedure is summarized as follows: A. The adsorbent cartridges are loaded with internal standards and surrogates prior to loading the autosampler with the cartridges. The loaded cartridges are purged in a helium flow. Then the cartridges are thermally desorbed in a helium flow onto a focusing trap. Any analytes in the helium stream are adsorbed onto a focusing trap. B. Following trap focusing, the trap is thermally desorbed onto a DB-VRX 60m, 0.25 mm ID, 1.40 micron filament thickness capillary column. C. The GC/MS is scanned between 35 and 270 Atomic Mass Units (AMU) at 3.12 scans per second. D. BFB tuning criteria and the iniliai five-point calibration procedures are those stated in method SW846-8260B. System performance and calibration check criteria are met prior to analysis of samples. A laboratory method blank is analyzed after the daily standard to determine that the system is contaminant-free. E. The instrumentation used for these analyses includes: Agilent 6890-5973 Gas Chromatograph/Mass Spectrometer; • Markes Unity thermal desorber; • Markes UltrA autosampler; and Markes Mass Flow Controller Module.

This unit was previously designated as the north sump but from facility drawings it is more accurately describe as the west sump. The sump was installed in August 1964 and remained in service until November 1988 at which time it was removed. The building is used for storage of aluminum and polymer. 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 vicinity 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 material 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 Performance Propellant Development 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 Compliatice Plan prepared for Thiokol by Underground Resource Management, Inc., in August 1985. Well TCC3 was drilled 350 feet below 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 tjepth 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 building discharge consisted of wastewater from housekeeping activities within the building and for collecting materials in the event of a spill.

M212-], REV. #e Figure 149-2 The constituents of concern for this site were identified as volatile organics, metals, and explosive constituents.- Soil Characterization 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 vertical permeability values for the soils at Thiokol range from 4.2 x 10'^ to 1.4 x 10'^ centimeters per second (cm/sec) (Chadwick, et a!., 1975^. These values indicate that surface water will infiltrate slowly to moderately! Hupp and Thiokol soil types have slight to moderate use limitations, while all other soil types have moderate to severe use limitations. The Soil Conservation Service has noted slow permeability, land slopes, and shallow bedrock as reasons for the use limitations. investigation Activity During the RFI conducted at this site, two soil borings were drilled in the area identified from facility maps as the location of the west sump. The borings were advanced to a total depth of 10 feet with samples collected from 5- and 10-foot depths. Collection of the samples was according to the following procedure: 1. Using a clean auger, the hole was advanced to the prescribed depth. A clean, stainless steel, split-spoon sampler was driven approximately 18 inches into the undisturbed soil. The split-spoon sampler was retrieved from the hole and carefully opened. 2. The core was measured to find the required sample depth. Using a stainless steel spatula or spoon, a portion of the soil was placed into 8 oz, precleaned, sample jars with a teflon coated seal. The jars were sealed and stored in a cooler at approximately four degrees Centigrade. 3. The sample location, depth, soil lithology, duplicate label, and other observed information were recorded in the log book Decontamination of equipment used in sample collection was according to the following procedure; 1. All equipment entering the boring was either steam cleaned with Alconox soap or scrubbed with a brush in a wash basin or bucket containing Alconox soap and water. Washing was followed by a tap water rinse and a final rinse with deionized water. All wash and rinse water was collected for appropriate disposal at either Thiokol's chemical wastewater treatment facility or biological wastewater treatment facility. Analyses of the soil samples were performed by Thiokol's environmental laboratory using EPA approved methods. Thioko!

The results were further qualified as also 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. Figures 149-3a-c are visual representations of the constituent concentrations at this site compared to background. Also shown are statistical representations of the analytical data collected for this site during the RFI. The box and whisker plot illustrate the comparison in the median values (small box) for the respective constituents to the median background value. The larger box represents the range from the mean minus 25% to the mean plus 25% of the data, with the whiskers projecting OLrt to the maximum and minimum values. The metals beryllium, cadmium, chromium, lead, and mercury were generally detected in all samples. Nitrate was the only explosive constituent detected in any of the samples for this site. Comparison to Baclcground Concentrations Upon inspection of Figures 149-3a-c and Table 149-3, it can be seen that concentrations for all inorganic constituents are within the respective ranges found in background soil at Thiokol.

Comparison to Risk-Based Levels The maximum value of trichloroethene (20 ug/kg) detected during the RFI for this site does not exceed either the EPA Preliminary Remediation Goal (PRG)or the Proposed Subpart S action level. All metal concentrations were below the respective PRG and Subpart S action levels. Conclusions The RFI conducted at this site did indicate the presence of TCE in the deeper soil samples. However, the maximum value of TCE at this site does not exceed either the EPA Preliminary Remediation Goal or the Proposed Subpart S action level for solid waste management units. Although there is evidence of TCE at this site, it can be concluded that due to the low concentrations, the remote location, and the controlled environment for the facility that this site does not pose a risk to human health or the environment. Recommendations for Additional Work Based on the findings of the RFI conducted at this site, Thiokol believes there is no further action needed for this site.
