EXECUTIVE SUMMARYThe following documents require that a hazard classification be prepared forall activities for which United States Department of Energy (DOE) has assumedenvironmental, safety, and health responsibility: The DOE Order 5481. lB,Safety Analysis and Review System and DOE Order 5480.23, Nuclear SafetyAnalysis Reports. A hazard classification defines the level of hazard posed byan operation or activity, assuming an unmitigated release of radioactive andnonradioactive hazardous material.For environmental restoration activities, the release threshold criteriapresented in Hazard Baseline Documentation (DOE-EM-STD-5502-94) areused to determine classifications, such as Radiological, Nonnuclear, and OtherIndustrial facilities.Based upon DOE-EM-STD-5502-94, environmental restoration activities inall but one of the sites addressed by the scope of this classification (see Section2) can be classified as "Other Industrial Facility. " DOE-EM-STD-5502-94states that a Health and Safety Plan and compliance with the applicableOccupational Safety and Health Administration (OSHA) standards are sufficientsafety controls for this classification.V

Hazard Classificationof Environmental Restoration Activitiesat the INEL1. INTRODUCTIONUnited States Department of Energy (DOE) Order 5481.1B, Safety Analysis and Review System'and DOE Order 5480.23, Nuclear Safety Analysis Reports2 require that a hazard classification beprepared for all activities for which DOE has assumed environmental, safety, and health responsibility.A hazard classification defines the level of hazard posed only by potential releases of radiological andnonradiological hazardous materials from an operation or activity, assuming no mitigating systems areavailable.DOE-EM-STD-5502-94 classifies facilities and activities as Nuclear, Nonnuclear, Radiological,and Other Ind strial. The classifications are based only on the releasable quantity thresholds listed in40 CFR 302,4DOE-STD-1027-92,5 29 CFR 1910.119,6and 40 CFR 355.71
2. ACTIVITY DESCRIPTIONThis classification is intended to envelop restoration activities performed by EnvironmentalRestoration (ER) and their subcontractors. The majority of these activities take place outdoors andinvolve working with relatively small volumes of liquid, soil, and waste that may be contaminated withradionuclides, chemicals, or both.ER activities are under the management of the ER directorate organization. The waste areagroups (WAGS) and the areas that comprise each WAG are identified in Table 1. Some ER activitiesare excluded from using this hazard classification. Activities that are excluded include:Radioactive Waste Management Complex (RWMC), which has a Safety Analysis Report(SAR) that addresses activities inside the RWMC fenceAreas where unexploded ordnance are presentAny activity for which nuclear criticality has been identified as a valid concern.Characterization activities include soil sampling; well drilling; liquid sampling from wells, ponds,or tanks; and sediment sampling from ponds, tanks, or the ground surface. These activities include awide variety of accepted sampling methods and matrices and typically involve small volumes ofmaterial.Remediation activities include soil removal using earthmoving equipment (backhoe, front-endloader, etc.) or by hand; cleanup of contaminated liquids; removal of waste (mixed) from undergroundstorage tanks (USTs), in situ grouting of USTs, removal of USTs; and capping and monitoring ofcontaminated sites.During ER activities, health and safety protection will be implemented by the Health and SafetyPlan (HSP) written for each ER activity. The HSP provides specific guidelines to minimize health andsafety risks to the worker and public. The HSPs are prepared in accordance with 29 CFR 1910.120,Hazardous Waste Operations and Emergency Response.2

3. HAZARD CLASSIFICATION APPROACHFigure 1 shows the DOE-EM-STD-5502-94 classification process recommended by DOE for allenvironmental management activities. This process was used to determine the appropriate hazardclassification for ER activities.The hazard classification process requires the following: (a) the contaminants and corrcspondingthreshold quantities (TQs) in DOE-STD-1027, reportable quantities (RQs) in 40 CFR 302 Appendix Bfor radioisotopes and Table 40 CFR 302 for nonradioactive hazardous materials be identified, (b) anestimate of the quantities of Contaminants at the remediation or characterization area, (c) a determinationof the ratio of the assumed quantities to the TQs and RQs, (d) a sum of the ratios, (e) an adjustment ofthe sum of the ratios by a ratio of 1E-03 (the most conservative release fraction used to determine theTQs and R Q s ) to a less conservative but defensible release fraction, and (f) use the actual releasefractions found in Reference 8 for each radioisotope if 1.OE-03 is too conservative for a site. Severalconservative assumptions were used in arriving at the sum-of-the-ratios to ensure the enveloping of ERactivities addressed by this hazard classification. These assumptions are discussed in the followingparagraphs.The data tables in Appendix A list the contaminants, the assumed concentrations in soiVwaste andwater, the associated TQs and RQs, and the adjusted sums of the ratios. The list of contaminants and theassumed concentrations are an aggregate of the maximum concentrations of recorded sample analysisresults recorded for WAGS addressed by this hazard classification (see Section 2).9It is assumed that the release volumes are 1 m3 of soillwaste and 4,000 L of water. The assumedvolumes are high for characterization activities and most remediation activities and results in a muchlarger airborne release of material than would be expected. These assumed volumes will bound activitiescurrently planned by ER for calender year 1996.The release fraction for contaminated liquids is assumed to be the same as for contaminated soil.This assumption results in a much larger airborne release of material for a liquid than would beexpected.When summing the ratios, it is assumed that a single restoration activity will involve all thecontaminants found to date and at the maximum concentrations measured to date. These conditions areassumed only to ensure that ER activities are enveloped by this hazard classification. The list ofcontaminants and the assumed concentrations should not be used as screening thresholds to determine iffuture ER activities are enveloped by this classification.The hazard classification is segregated for operable units that because of high concentrations ofcontaminants result in radiological or nuclear facility hazard classifications rather than standardindustrial.4

4. HAZARD CLASSIFICATIONThe sum of the ratios of releasable quantities compared to the TQs and RQs is less than 1.O for alloperable units (OUs) addressed by this hazard classification except OU 3-07 (see Appendix A).Therefore, ER activities in areas other than OU 3-07 and not excluded from this classification (seeSection 2) may be classified as “Standard Industrial” and an auditable safety analysis or SAR is notneeded.Assuming a release volume of 1 m3, and the actual release fractions found in Reference 8, the sumof the ratios for OU 3-07 is less than one when compared to the TQs but is greater than one (actual valueis two) when compared to the RQs. This site may still be classified as “Standard Industrial” only if theactual volume of potentially releasable soil is less than the volume assumed in the calculations; otherwiseit is classified as ‘‘ Radiological.”Excluding OU 3-07, the sum of the ratios will be less than one for the TQs and RQs even if theassumed volume of soil/waste or water contains all the radioactive and nonradioactive hazardousmaterials at the maximum (assumed) concentrations measured to date (1/96) for soil/waste and waterAdding the sums of the ratios for soil/waste and liquids equals 6E-04 when considering the TQs only(applies only to radionuclides) and 6E-0 1 when considering the RQs (radionuclides and hazardousmaterials). Therefore, the hazard classification will be “Standard Industrial.”This classification is conservative in the extreme and will envelope all typical characterizationactivities and most remediation activities at the INEL. The LMIT Chemical and Radiological RiskAssessment Department (CRRAD) should be consulted for all remediation activities to ensure that theyare enveloped and for characterization activities involving large volumes of materials in a singlecontainer. Activity specific sum-of-the-ratio determinations may be required if there is a potential for aspill of volumes significantly greater than (Le., a factor of two) 1 m3 for soils and wastes and 4,000 L forliquids. It must be noted that the volumes assumed in an activity-specific determination relate only tomaterial spilled in a single event, not the total volume of material stored at a site, involved in a remedialaction, or that may be spilled over the course of an action.This hazard classification will be updated yearly by the CRRAD to include new sample data and toensure that the assumed concentrations are still bounding.6

Appendix AContaminants and Sum-of-the-Ratio CalculationsINTRODUCTIONThis appendix provides the basis for determining the hazard classification of ER activities. TablesA-1 through A-5 list the contaminants, the maximum measured concentrations of each contaminant, thenuclear facility threshold quantities (TQs) from DOE-STD- 1027-92, the reportable quantities (RQs)from 40 CFR 302 Appendix B for radionuclides, and Table 40 CFR 302 for nonradioactive hazardousmaterials, the ratio of the RQs to the maximum quantities, and the sum of the ratios.The list of contaminants and their maximum concentrations are from about six years of sampleand analysis data reported in decision document packages, Track 2 preliminary scoping packages,hazard classifications, historical data reports, record of decisions, feasibility study reports, remedialinvestigatiodfeasibility study reports, treatability studies, Health and Safety Plans, Track 2 summaryreports, and closure reports for operable units within the waste area groups addressed by this hazardclassification.Several equations were used to derive data in Tables A-1 through A-5. Some required a soildensity value or a factor to adjust the TQs and RQs assuming a less conservative but defensible releasefraction. The assunied soil density was taken from Reference A-1 and the assumed release fraction isfrom a draft EM hazard categorization standard that is based on Reference A-2. Although still draft atthe time of this report, the EM standard has been through final review and comment resolution and iswaiting issuance (per tele-con with Howard Goldin, author of the standard).The assumed soil density for all sites at the INEL is 1.5 g/cm3 (1,500 kg/m3). An airbornerelease fraction (ARF) of 5.OE-06 is assumed for a spill of soils/wastes and liquids. For all but one site,the sum of the ratios is adjusted by the ratio of this ARF to an ARF of 1.OE-03 which is the mostconservative value used to calculate the TQs and the RQs.*” Because of relatively high soilconcentrations, assuming a release fraction of 1E-03 for all radionuclides at the OU 3-7 site results inan overly conservative classification. For this site only, the actual release fractions found in ReferenceA-3 for each radionuclide were used in determining the hazard classification (see Table A-5). Avolume of 1 m3 is assumed for soil/waste and a volume of 4,000 L is assumed for liquid. The assumedvolumes are based on the approximate volume of a front-end loader bucket and the representativevolume of water purged and collected during ground water sampling. Equation (1) through Equation(4) were used to calculate the data listed in Table A-1 through Table A-5.A-3
