RE: Summary of September 2002 Soil Remediation - OrganicChemicals, Inc. Gnndville, Michigan
Dear Tom:
This letter is being submitted to summarize the re.r.pm (September 2002)jactivities at the Organic Chemicals, Inc. Superfund Site (OCI Site). The!completed under the direction of Compliance, Inc. on bcllitlf of TPl Petroleum, Inc. asoutlined in our August 14,2002 correspondence,
remediationactivities were
During the September remediation activities, approximately 1000 yard?material comprising a gray layer that was identified at the site were excaexcavated materials are currently stockpiled on the south side of the sitedisposed off-site at appropriate disposal facilities following the receipt o:characterization data aud disposal approval. It is anticipated that the off-
'f soil and/orrated. Theseuid will be'therite disposal will
begin in early October and will be completed by the end of the month.
The gray layer was excavated and removed from all, or portions of, the fallowing grids(see the attached figure for a summary of all soil remediation areas):
K10,J10,J12,K12,L15,L16,L17, O14, H14, AA12, and BB12.
Additionally, surface soils (generally from 0 to 2 feet below ground sur&fce) wereremoved from the following grids: [
t
I10,J10,KIO,I11,I12,G13,H13, iI13,G14,Hl47G15,H15,andH16. ;
The removal of the additional soil from the above listed grids was aasocia :ed wilhachieving the risk based cleanup goal for carcinogenic chemicals and was separate fromthe work to address the gray layer. Six post removal soil verification sam Jles werecollected from randomly selected locations in the soil removal grids listed above. Thesamples were collected per the methodology presented in the Final Desig4 Report. The

samples (labeled SS-334 through SS-339; were collected on SeptembetU S. EPA's inspection of the site. These samples were submitted m So
13,2002 duringnthwest Labs of
Oklahoma tor analysis for the eleven chemicals of concern at the site. Jhe analyticalresults were received electronically on September 26, 2002,
j
The analytical results of the six j>oil verification samples have been add d to the databaseof RI/FS, Pre-Design and Verification Soil surface and near surface soil 5 samples Thisdatabase is presented on the on the attached table. As seen on this table with the additionof these analytical results, the total worker carcinogenic risk is 1 x 10"4 • vhkh meets theSOW specified carcinogenic risk remediation gual. Additionally, with t le addition ofthis data, the calculated sitewidc 95% UCL for lead in soils is 695 mg/k r. Thisconcentration is below the 900 mg/kg standard established for lead i
It is notable that all of the carcinogenic chemical concentrations in the soil databasepresented on Table I are below their respective Part 201 industrial site direct contact soilcriterion. i
All of the activities outlined above will be presented in greater detail in t final summaryreport that will be prepared following off-site disposal. Tf you nave any Questions in theinterim, please do not hesitate to call me.

FINAL REMEDIAL DESIGN
Organic Chemicals, Inc. SiteGrandville, MI
On behalf of TPI Petroleum, Inc. (TPI), Compliance, Inc. has prepared this final design for soilremediation at the Organic Chemicals, Inc. (OCI)) Site in Grandville, Michigan. This reportpresents the rationale and protocols for soil remediation tasks for this site. The soil remediationthat is the subject of this report is being completed as a part of the CERCLA response actions forthis site. The work is being completed in accordance with the Consent Decree dated September28. 2000 and its associated Statement of Work (SOW) between TPI and the United StatesEnvironmental Protection Agency (U.S. EPA).
The OCI site is located at 3291 Chicago Drive. S.W. in Grandville. Michigan. During its periodof operation, OCI manufactured specialty industrial chemicals and pharmaceutical intermediates.OCI also operated a solvent recovery operation. The company operated from the late 1960s tothe early-1990s, prior to which the site was used as a bulk petroleum terminal and as a crude oilrefinery beginning in the late-193Os.
The OCI site has been the subject of various environmental investigations beginning first by theMichigan Department of Natural Resources (MDNR) in the mid-1970s and later under thedirection of U.S. EPA in accordance with the Comprehensive Environmental ResponseCompensation and Liability Act (CERCLA). The U.S. EPA investigation documented soilimpact at the OCI site that could pose a health threat to a future worker at this site.
This report is divided into two separate major parts. Part I presents an evaluation of the soil datacollected by U.S. EPA during their Remedial Investigations of the site and soil data collectedduring the Pre-Design soil investigations completed by Compliance. Inc. in May and August2001. The evaluation presented in Part I assesses potential risks associated with soil impactwithin the facility'. That evaluation identifies, from this risk assessment, the areas of the sitewhere soil remediation activities are required to meet the project goal.
Part II of this work plan presents the scope of work for addressing those soils identified forremediation. This part describes site preparation, soil excavation, and off-site disposal activities.Part 2 also describes the remediation activity monitoring and site health and safety procedures.The methodology for final soil verification sampling after the removal of soils is also outlined inPart 2.

SUMMARY OF INDICATOR CHEMICAL CONCENTRATIONSFOR THE PURPOSE OF DEFINING AREAS REQUIRING SOIL REMEDIATION
1.0 BACKGROUND INFORMATION
1.1 U.S. EPA RI Soils InvestigationsThe past investigations of the OCI site are generally summarized and presented in U.S. EPA'sPhase II Remedial Investigation (RI) report dated June 17, 1994. With regards, to surface andnear surface soils, the RI investigations collected over one hundred soil samples and subjectedthem to analysis for full scan VOCs, SVOCs, pesticides/PCBs and inorganics. A subset of thesesamples were also subjected to analysis for dioxins/furans.
Specific reasoning for the U.S. EPA's selection of each soil sampling location was not providedin the RI or in the Final RJ/FS Work Plan. General discussion presented in the RI indicates thatsampling was completed to determine the aerial extent of surficial soil contamination.Additional discussion in the RI also indicates that a bias towards visual or suspected areas ofimpact was used for some of the collected samples. Surface soil sampling was also moreconcentrated in and around the tank farms, storage areas, and site chemical handling buildings.
Given the bias used to select many of the sample locations and the greater frequency of samplingin areas known or suspected to be the location of past releases, it is believed that the databasegenerated by the RI sampling was not likely to underestimate the typical site chemicalconcentrations to which a future worker could be potentially exposed. This database was used byTPI as the initial basis for assessing site risks and for determining where to focus the Pre-Designsampling completed in May 2001.
As specified in Section 2.2.1 of the U.S. EPA RI. surface soil samples collected by U.S. EPA'scontractor at the site were collected from the two to six inch depth interval. This depth intervalwas generally characterized as a sandy gravel. The samples were collected by hand tools ordirectly by hand. Approximately 84% of the site soil data used in U.S. EPA's risk evaluation ofon-site soils was collected from these depths. A smaller subset of the data used by U.S. EPA toassess risks to soils exposures was collected from depths below the surface (two to ten feet belowground surface (BGS). The subsurface soil samples were reported as being collected using athree-inch diameter ring lined sampler. The inclusion of a limited number of soil samplesfrom the two to ten foot depth interval recognizes that a portion of a future worker's soilexposure would likely come from soils below the site surface. The number of soil samplescollected from subsurface depths and used in the site risk evaluation was small relative tothe total number of site soil samples used to assess future worker exposures (approximately20 samples out of a total of over 150 samples).
Page 1
1.2 U.S. EPA RI Risk AssessmentThe chemicals detected in the surface soils during the U.S. EPA RI were subjected to a riskassessment completed according to U.S. EPA's Risk Assessment Guidance for Superfund(RAGS). The Phase II RI risk assessment identified twelve chemicals of concern thatrepresented a majority of the calculated site health risks. Eleven of the chemicals of concern areknown or suspected human carcinogens and these chemicals accounted for over 95% of the totalsite carcinoeenic risk. The twelve chemicals of concern are listed below:
BerylliumChromium (VI)LeadBis(2-ethylhexyl)phthalateBenzo(a)anthraceneBenzo(a)pyreneBenzo(b)fluoranmeneDibenzo(a,h)anthraceneIndeno( 1,2,3-cd)pyreneAroclor-1248DieldrinDioxins/Furans (2,3,7.8-TCDD Equivalents)
The Phase II RI identified the carcinogenic risks to future site workers associated with thesechemicals in soils to be 2.8 x 10"4. Because the carcinogenic risks were determined to be outsideof U.S. EPA's target carcinogenic risk range (1 x 10"6 to 1 x 10"4) and because elevated leadconcentrations were present, an evaluation of potential soil remedies was undertaken.
1.3 Soil Cleanup GoalAs specified in the SOW and Consent Decree for this site, the goal for the soil remediation is toexcavate and dispose off-site, or treat and retain on-site. contaminated soil and debris until thesite wide soils meet the 1 x 10"4 excess cancer risk required by the ROD. The stated remediationgoal also includes a demonstration that a cleanup standard for lead in soils of 900,000 ug/kg isachieved at this site in accordance with the MDEQ Guidance Document "Verification of SoilRemediation" April 1994, Revision 1.
The risk assessment methodology used to determine that the soil remediation goal forcarcinogenic chemicals is achieved is the methodology used by U.S.EPA in the Phase II RI. Thismethod is in accordance with U.S. EPA's Risk Assessment Guidance for Superfund (RAGS). Asevidenced in the Phase II RI and in accordance with RAGS, the calculated carcinogenic riskattributable to any individual chemical in soils at the OCI Site is directly proportionate to thecalculated exposure concentration for that chemical. The carcinogenic risk for an individualchemical after soil remediation (CR^), can be determined by the following formula:
Paee2
CRAR = CRBR *where:
CRfiR = Carcinogenic risk before remediation (unitless)£CAR = Exposure concentration after soil remediation (ug/kg or mg/kg)ECeR = Exposure concentration before soil remediation (ug/kg or mg/kg)
Per the Phase II RI and RAGs, the exposure concentration is the 95% upper confidence limit of the mean(95% UCL) concentration.
The total carcinogenic risks attributable to the eleven chemicals of concern following soilremediation is the sum of the individual risks for each chemical (the sum of the CRAR'S)determined as above. The estimated individual and chemical risks and risk reduction presentedlater in this report are determined from this methodology.
It is noted that the U.S.EPA RAGS-based risk assessment process used for this site differs fromthat used by MDEQ to determine Part 201 generic industrial site soil criterion. The process usedby U.S. EPA applies exposure factors that result in more conservative (lower) cleanup criteria forcarcinogenic chemicals than would be determined using Part 201 generic industrial site soilcriterion. Further discussion of the greater protectiveness of the approach being used for this siteversus the use of MDEQ soil criteria is presented in Section 3.5 of this Part.
1.4 Elimination of One or More Chemicals of ConcernAs specified in the SOW, during the Pre-Design investigation, the chemicals of concern wereevaluated for potential elimination from the risk assessment for this site if they met any of thefollowing criteria: 1) if it could be determined that the chemical no longer exhibits intrinsictoxicological properties, 2) if it could be determined that the chemical is no longer present inlarge quantities, or 3) if it could be determined that the chemical is not presently in or potentiallygoing to move into critical exposure pathways (e.g. direct human contact or ingestion). The pre-design soil sampling was used to generate data sufficient to support a conclusion that chromium,which, for risk assessment purposes, was assumed to be present as chromium VI, was not presentin this more toxic valence state. Therefore, chromium VI was eliminated from the riskassessment based on its relative absence. A specific discussion of the sampling completed tomake this demonstration is presented in Section 2.4 of this Part.
2.0 SCOPE AND RESULTS OF PRE-DESIGN SOIL INVESTIGATION
The pre-design soil investigation was completed to provide both additional data needed to definethe lateral extent of soils requiring remediation and to determine whether the U.S. EPAFeasibility Study (FS) assumed two foot depth of soil removal would be adequate to reduce sitesoil exposure risks. To accomplish this, both lateral and vertical definition soil samples werecollected during the pre-design investigation. A discussion of the pre-design sampling locationsand results is presented in the remainder of this section.
Page3
2.1 Pre-Design Lateral Definition Sample LocationsThe lateral definition soil samples were collected from the locations numbered SS-200 to SS-261and SS-278 to SS-287 as presented on Figure 1. The lateral definition sample locations includedsamples from locations that adjoin areas initially identified for potential remediation using theU.S. EPA RI data. Additional lateral definition samples were also collected from severallocations identified by the MDEQ as areas of the site requiring additional sampling tosupplement the site database.
Soil samples were collected according to the soil sampling procedure specified in the QAPP forthis site, which also, per U.S. EPA Region 5 guidance, is serving as the Sampling and AnalysisPlan for this project. Specific sample collection methodologies are discussed in section B.2 ofthe QAPP and in the Standard Operating Procedures (SOPs) presented in Appendix C of theQAPP. One duplicate sample was included for every group often or less soil samples collected.
All of the lateral definition samples were collected as non-composited surface soil samples fromthe 0 to 6 inch depth interval. In general, the samples were collected using a stainless steel handtrowel from an area of lateral dimensions sufficient to provide enough soil to fill all sampling jars(including any requested MDEQ/U.S. EPA split samples). The samples were first collected intostainless steel bowls, mixed and then placed into sampling jars following exclusion of stones andvegetative material. In a few instances, sampling was limited to less than six inches bysubsurface obstructions. In those cases, the soils were collected over the sampling interval thatcould be achieved generally no less than zero to four inches.
As seen on Figure 1. the combination of all RI and pre-design soil sample points provides lateralcoverage of the entire site. The sampling locations were generally spatially distributedthroughout all areas of the site. A greater frequency of sampling is" observed in and around areasearmarked for remediation. As with the original U.S. EPA soil sampling, this greater samplingfrequency in and around suspected/known areas of greater impact is believed to bias the siteaverage chemical concentrations upward. The subsequent risk evaluations completed using thisdata are believed to produce conservative estimates of potential human health risks.
2.2 Pre-Design Vertical Definition Sampling LocationsThe pre-design vertical definition samples were collected from eighteen locations at the site. Allsixteen of the locations were within areas initially identified for soil remediation based on theU.S. EPA RI data. These sample locations, labeled SB262 to SB-277 and SB-288 and SB-289,are shown on Figure 1. The samples locations included at least one from each discrete areainitially identified for remediation (two from the larger area between the north tank farm and thedrum storage area).
The subsurface soil sample locations were selected because they are in the areas initiallyidentified for soil remediation (where the depth of removal must be determined) and because they
Page 4
represent the areas of the site identified in the RI sampling as having the greatest surficial soilimpact. These areas were believed to be areas with the greatest potential for vertical migration ofcontaminants. As a part of the investigation design, the 2.0 to 2.5 foot sample was selected totest the FS assumption that the impacted areas of the site will require remediation to the two footdepth. The second sample collected in each boring (nominally from 4.0 to 4.5 foot) was collectedto provide additional data, should the shallower sample show the presence of chemicals thatrequire remediation.
The vertical definition sampling was designed to collected non-composited grab samples fromthe 2.0 to 2.5 foot and the 4.0 to 4.5 foot depth intervals. The sampling was generallyaccomplished using a GeoProbe. Hand auger techniques were initially attempted but provedunsuccessful due to the gravel content of the surface soils. However, in a few locations, theGeoProbe sampling was supplemented by hand auguring. Prior to GeoProbing through thesurface soils, an approximately two foot by two foot wide hole, about 1.5 feet deep was hand dugin the sampling locations. This initial hole was completed to remove surface materials that mightpose a carry down threat using the prescribed subsurface sampling equipment. Soil samples werethen generally collected using a five feet long, two-inch ID macrocore sampler. The sampler wasdriven down to five foot bgs. Multiple samplers (up to three) were driven at each location toproduce enough soil sample for the required laboratory analysis from the selected depth intervalsat each location.
Samples were collected from the recovered core and segregated into an approximate 2 to 2.5interval sample (labeled with the suffix ''B") and an approximate 4 to 4.5 foot sample (labeledwith the suffix "C"). The actual sampling interval is considered approximate because, due to thenature of the subsurface soils, 100% recovery was not achieved in each sample core. Table 5lists the sample methods, sampler recovery and depth intervals used for the B and C samples. Asnoted on Table 5, at four locations, sample recovery was limited such that only a single intervalwas subjected to laboratory analysis. At these locations, the sample was given the B suffix butcan not be more specifically characterized than as being a likely composite over the 2.0 to 4.5foot depth interval. Likewise, in sample locations where recovery was less than 100%, the B andC samples should be considered to represent approximations of the nominal depth intervals (2.0to 2.5 and 4.0 to 4.5). Those samples collected by hand auger, were collected from theprescribed depth intervals.
2.3 Surface and Subsurface Soil Sample AnalysesA majority of the soil samples were analyzed for ten of the twelve indicator chemicals includingthe five PNAs, lead, beryllium, BEHP, dieldrin and Aroclor 1248. A smaller subset of thesamples were analyzed for chromium VI and dioxins/furans. Several samples were also selectedfor either lead or Aroclor 1248 sampling alone.
The analytical methodologies used are listed below.

Detailed SOPs for each of the analytical methods were presented in Appendix A of the QAPP.
2.4 Summary of Pre-Design Sampling Analytical ResultsThe sample result data sheets for all pre-design samples are presented in Appendix A. The datavalidation report for these samples is included as Appendix B. The results of the sampling areevaluated in detail for risk assessment purposes in Section 3.0 of this Part.
Notable aspects of the sampling analytical results include:
• Chromium VI was either not detected or detected at concentrations below 1 mg/kg in allof the soil samples collected in the pre-design sampling. These concentrations were over1.000 times lower than the highest concentrations of total chromium and over 100 timeslower than the 95% UCL concentrations for total chromium presented in the RI. As such,any potential risks associated with the presence of Chromium VI at the site are 2 to 3orders of magnitude lower than the presumed 1.4 x 10"5 risk level presented in the RI riskassessment. This would correspond to less than or equal to 1 x 10"7 cancer risk. For thisreason, chromium is not included further in the site risk evaluations.
• With the exception of lead in one location, the subsurface B samples (nominally from the2.0 to 2.5 foot interval) were as a whole significantly lower in indicator chemicalconcentrations than the corresponding surface soil samples collected in the RI sampling.These data support the conclusion that a 2.0 feet excavation depth is sufficient to producethe desired risk reduction over most of the site.
• The above conclusion is further supported by the fact that the subsurface C samples(nominally from the 4.0 to 4.5 foot interval) also had substantially lower indicatorchemical concentrations. In only one instance, was a target analyte found in a C labeledsample at a concentration that would require soil remediation.
Page 6
The two noted exceptions to the above findings concerning subsurface depths were:
1) The presence of lead in the SB-263B sample at 12,500 mg/kg. The C sample at thislocation showed a substantially lower lead concentration of 51 mg/kg. That data suggeststhat any soil removal in this location would need to extend to approximately 3 to 3.5 feet.
2) The presence of Aroclor 1248 in the SB267C sample at 60.000 ug/kg. At this location,the surface soil and the B depth interval samples showed substantially lower levels ofAroclor impact. At the four foot depth interval, the soils had an organic chemical odor(this was the only location out of the sixteen subsurface soil sample locations wherevisual/olfactory evidence of impact below 2.0 feet was observed). This location is near/inthe former seepage lagoon area. The impact identified is believed to be residual from thatsite feature.
Noting that additional characterization is necessary in the areas surrounding SB-267C, the Pre-Design data is considered sufficient to conclude that the two foot depth interval for remediationwill adequately reduce site risks. The only location where the B/C samples suggest potential forhigher impact at depth is in the sample collected from an area of the site where subsurface impactwas the result of a previous^ known site feature which by design would cause subsurface impact(the former seepage lagoon). The pre-design investigation did not suggest that other subsurfaceareas of the site show a similar potential for increasing chemical concentrations with depth.Based on these findings, no additional deeper investigation (with the exception of the seepagelagoon) is considered necessary.
3.0 EVALUATION OF ALL SOIL SAMPLING DATA FOR THE IDENTIFICATIONOF SOILS REQUnUNG REMEDIATION
3.1 Combined RI and Pre-Design Soil DatabaseTable 2 lists the entire site surface soil database which is a combination of the 106 surface andnear surface soil samples used by U.S.EPA in the initial site Risk Assessment (as presented onTable 6-2 of the Phase II RI Report) and the 71 pre-design surface soil samples collected byCompliance, Inc. Data presented in this data base is for the ten remaining chemicals of concernidentified in the RI except dioxins/furans. Data for dioxins/furans, used to determine the 2,3.7.8-TCDD equivalency for each dioxin/furan sample is summarized in detail on Table 3. Thelocations from which the samples were collected are presented on Figure 1.
The concentration entered into the database presented as Table 1 is the actual detectedconcentration when the chemical was identified as present. If the chemical was not detected, aconcentration equal to one-half the reported detection limit for that sample was entered. Thisinterpretation of the data follows that used by U.S. EPA in the RI and that recommended inRAGS.
Page 7
It is notable that for several of the target analytes (primarily PNAs), a substantial number ofsample points from the RI and some from the pre-design sampling were reported as non-detectbut had elevated detection limits. Elevated detection limits introduce uncertainty into anassessment of site risks and the identification of locations of the site requiring remediation. Theconvention used by U.S. EPA and the convention followed in this Work Plan (to assume that achemical reported as non-detect was present at a concentration equal to one half the detectionlimit) is a conservative means of accounting for this uncertainty. This convention mayoverestimate the risks posed by several chemicals at the OCI Site. As an example, as seen onTable 1. for several of the PNAs, a majority of the highest chemical concentrations assumed to bepresent are actually from non-detect samples where half of the reported elevated detection limit isused.
The uncertainty associated with elevated detection limits is lessened by the fact that thechemicals primarily affected by elevated detection limits contribute a relatively small percentageto the overall site risks. Specifically, PNAs and BEHP were the chemicals most often reportedwith elevated detection limits but these chemicals contributed only about 12% to U.S. EPA'scalculated overall carcinogenic risks for the worker scenario. Chemicals contributing higherpercentages to the site risks (e.g., Aroclor 1248, dieldrin and TCDDs/TCDFs) have data sets thatwere generally not affected by non-detect data with elevated detection limits. Additionally, thedata set for lead, handled as a non-carcinogen, was not affected by elevated detection limits.
3.2 Subsurface Soil Sampling DataData for the 32 subsurface soil samples collected during the pre-design investigation are alsopresented on Tables 2 and 3. This data is used to determine the appropriate depth of remediationfor the proposed remedy. As seen on Table 2, with relatively few exceptions, the subsurface datais substantially lower in maximum and average indicator chemical concentrations than thesurface soil data base.
With the exception of lead at the SB-263B, the B labeled samples for all of the analytes aregenerally significantly lower in chemical concentration than the surface soil samples. Thisincludes the Aroclor 1248 concentration in SB-266B, which while higher. 40,000 mg/kg, issignificantly lower than the surface soil concentrations in this location. 74.000 identified in SS-81). With the exception of the sample at SB-263B and SB-266B. the data supports theconclusion that remediation to no deeper than the two foot depth interval is required at this site(in the SB-263 and SB-266 locations, the C sample interval suggests that a removal ofapproximately 3 feet may be warranted).
The deepest samples collected (those labeled C) were also seen to have generally lowerconcentrations than the B labeled samples. With the exception of the SB-267C sample, the datadoes not suggest that soil removal below 2.0/3.0 feet is warranted. It also did not produce datathat would suggest that depths greater than 4.5 feet require further characterization. Theexception to this finding, the Aroclor 1248 concentration in the SB-267-C sample, will requireadditional soil characterization prior to remedy implementation in the area of that sample.
PageS
Excluding the lead concentration in SB-263B and the Aroclor 1248 concentration in SB-266B,the average concentration of all of the target analytes in the B labeled samples collected in May2001 (SB-262 to SB-277) presented on Table 2 is used as the assumed post-remediation soilconcentration in the statistical evaluations presented in Section 3.3 below. While using this dataas the assumed post remediation sample concentration for design purposes, it is reiterated thatthis subsurface data will be supplemented with actual post removal verification sample collectionand analysis. A discussion of that sampling is presented in Section 2.5 of Part 2 of this report.
3.3 Calculated Carcinogenic Risks and Carcinogenic Risk Reduction EvaluationIn the Phase II RI, the total carcinogenic risks to on-site workers associated with exposure tochemicals in soil was determined to be 2.8 x 10"*. This risk level exceeds the acceptablecarcinogenic risk goal of 1 x 10"4 by approximately a factor of three. In order to meet the 1 x 10"4
carcinogenic risk remediation goal for this site, a sufficient quantity of the more highly impactedsoils must be remediated until the remaining soils exhibit a carcinogenic risk of 1 x 10"4 or less.The methodology for identifying which soils require remediation to meet this goal is presentedbelow.
In accordance with the SOW, risks from potential future chemical exposures are calculated on asite wide basis assuming future industrial use of the site. To support the use of the site wideassessment, the deed restriction to be emplaced on the site will prevent future uses other thanindustrial, and will prevent any subdivision of the site. The latter restriction eliminates thepossibility that a smaller parcel may be separated from the entire site and any subsequent need topredict and evaluate potential exposures based on possible smaller site subdivisions.
Consistent with the Feasibility Study/ROD approach. Figure 2 presents a gridded layout of theOCI site. On Figure 2, the site has been divided into approximately 500, 25 foot by 25 foot grids.This grid system was set up to identify locations of soil for which the analytical data indicatesremediation is or is not necessary. The 25 by 25 foot grid system was established for efficientremedial design and is not correlated with grid systems that would-be set for verification of soilremediation (VSR). It is noted that, after site remediation is completed, soil sampling in theremediated areas will be completed according to the work plan (see Section 2.5 of Part 2 of thisFinal Remedial Design).
Also consistent with the FS approach, as depicted on Figure 2, a number of the grids are shadedto indicate grids where removal/remediation of soils will reduce the cumulative carcinogenic riskfor the on-site soils to below 1 x 10~* for the future worker exposure scenario. The locationsidentified for removal generally correspond with grids containing soil samples with the highestconcentrations of the carcinogenic indicator chemicals (as presented on Table 2 and 3).
In order to assess the reduction in risks that will be achieved by remediating a particular grid, asshown on Table 4 the RI and pre-design determined chemical concentrations for the sample fromthat grid were replaced with concentrations that are assumed to be present in the remediated areaafter soil removal. The concentrations assumed to be present are the average concentrationsfound in the selected subsurface B samples as discussed in Section 3.2. For instance, sample SS-
Page9
93 has a higher Aroclor 1248 concentration (32,000 ug/kg) and, therefore, contributes relativelymore to site risks. This area of the site (Grid VI6) was, therefore, selected to be remediated tohelp achieve the risk reduction goal. Assuming that this grid is remediated, a concentration of1,500 ug/kg for Aroclor 1248 (the average of all subsurface B samples, excluding SB-266B) isused as a presumed post remediation concentration. This concentration is then entered in naturallog-transformed form into Table 4. (The natural log transformed data was used to calculate sitewide 95% UCL concentrations for ten of the remaining eleven chemicals of concern in the PhaseII RI. Consistent with the RI, normal (untransformed) data was used to calculate the 95% UCLconcentration for dioxins/furans).
It is noted that the actual chemical concentrations following remediation will be supplementedwith VSR sampling to be completed after the remediation. The following table lists the averageconcentration of each chemical of concern in the B subsurface samples. This Final Designassumes that these concentrations are in the remediated locations following removal (the logtransformation of that concentration is entered in Table 4 as the concentrations in these locationsfollowing remediation):

Those samples that are shaded on Table 4are the samples from locations to be remediated. Using the data presented on Table 4. it isdetermined that remediation of the indicated locations on the site will reduce the carcinogenicrisks for each of the indicator chemicals and for the site as a whole as follows.

It is noted that because there are ten carcinogenic chemicals of concern and because of theirvarying locations of greatest concentration, there are a number of ways to remove/remediate soilsto achieve the carcinogenic risk reduction goal. In general, the locations selected for remediationthat are shown on Figure 2 were: 1) selected to address the soils with the highest concentrationsof the chemicals contributing most to the overall site carcinogenic risk (e.g., Aroclor 1248); and2) selected for remediation from grids that are proximate to each other, to focus the remediationto specific areas, as best possible.
3.4 LeadAs shown on Table 4, the removal/remediation required to achieve the carcinogenic risk goal of1x10"* leads to a calculated site wide 95% UCL concentration for lead of approximately 580mg/kg. This is well below the 900 mg/kg remediation goal established in the ConsentDecree/SOW for this site. Therefore, no additional remediation of the site soils for lead (aboveand beyond that required for the carcinogenic chemicals) is warranted.
3.5 Comparison to Part 201 Industrial Site Soil CriterionAs mentioned above, the U.S. EPA RI risk assessment process differs from the process used todetermine Michigan Part 201 generic industrial site soil criterion. The differences, mainly in theexposure assumptions used in the assessment of risks, are such that the U.S. EPA-based approachresults in more conservative cleanup goals than that would be required to comply with MichiganPart 201 alone. A comparison of the Part 201 criterion to the calculated 95% UCLconcentrations and maximum concentrations after the remediation proposed above is completedis presented below.

As seen on the above table, all of the calculated 95% UCL concentrations after the proposedremediation would be well below their respective Part 201 industrial site soil criterion.
Furthermore, in only one case (for lead) is the maximum remaining concentration of anytarget analyte in any sample above the Part 201 industrial site soil criterion. Theexcursions above the lead criterion (mainly in samples from the northwest corner of thesite), while the 95% UCL remains well below the criterion, are not significant because:
• The extent of the exceedences are small. The maximum remaining leadconcentration exceeds its Part 201 soil criterion by less than a factor of three, and
• The 95% UCL concentration for lead in a smaller (2-acre) exposure unit that wouldinclude the entire northwest portion of the site with the higher lead concentrations is818,000 ug/kg. This concentration is below the MDEQ's 900,000 ug/kg industrialsite lead criterion (see Appendix D).
5.0 Summary of Remediation AreaFigure 2 outlines the areas of the site that contain samples that have been identified for soilremediation. Areas marked for remediation are those outlined in red. These areas contain one ormore of the samples selected for remediation in Section 4.0 (Table 4). Some areas proximate orbetween grids with the selected samples are also selected for remediation.
The remediation areas include most of the soil between the main building complex in the centerof the site, soils south of the North and South Chemical Buildings between the buildings and thesite fence, and an area of the site north of the Administration building/Aeration Tank.
The outlined area of remediation includes approximately 53 of the 25 x 25 foot grids. Theestimated in place volume of soil in each grid at a two foot removal depth (the depth of removalacross most of the site) would be approximately 46.3 yards. The estimated total in place volumeof soil requiring remediation, accounting for an excavation slightly deeper than two feet in a fewlocations is about 2.500 vards.

PART II
SOIL REMEDIATION FINAL DESIGN
1.0 INTRODUCTION
As presented in Part 1, the amount of soil currently identified for remediation at the OCI Site isapproximately 2,500 yards. Per the SOW for this work, TPI has determined that this represents avolume where off-site disposal will be the predominant means of soil remediation. At thisvolume of soil, off-site disposal has been determined by TPI to be as cost effective as othermeans of remediating site soils. Off-site removal has also been determined to have equal orgreater long term effectiveness and permanence as other remedies that could be employed.Because soils are not treated on-site prior to disposal, off-site disposal does not reduce thetoxicity or mobility of the soil materials. However, the mobility of contaminants from the soilsis limited given the nature of the chemicals of concern. Mobility would be effectively controlledby disposal in a secure, regulated off-site disposal facility.
In comparison to other potential remedies (e.g., solidification and on-site disposal of materials),the off-site disposal remedy has several significant advantages for promoting future industrial re-use of the site. One such advantage is that it does not leave material on-site that would requireongoing post remediation monitoring and cover maintenance. More importantly, it also does notcreate an area of the site that would be of potential limited future use for the construction ofbuildings.
Based on the above conclusions, this part of the design report presents those methodologies to beused for excavating, staging and off-site transport and disposal of the soil identified forremediation in Part 1. In presenting this plan, it is noted that certain aspects of the soil removalactivities will require coordination with, and the approval of, the selected off-site disposalfacility. Such coordination may require alterations/additions to the activities described herein.Such adjustments are not expected to significantly affect the general scope of work, however, ifsubstantial alterations are warranted they will be noted as addenda to this Remedial Design. AnyRemedial Design addenda will be submitted to the U.S. EPA for their approval prior toimplementation.
2.0 PROPOSED REMOVAL ACTIVITIES
2.1 Phase I Tasks - Site PreparationDuring Phase I. the site will be prepared for the soil removal activities. Specific steps to becompleted during this phase of work include the following.
Page 13
2.1.1 Construction of Decon/Access AreaA decontamination/access area will be constructed inside the site fence north of the sitegate (see Figure 1). All personnel and equipment entering and exiting the site will berequired to pass through this area for decontamination and/or inspection. Site workerswill be required to park personal vehicles outside the site fenced area or within a definedparking area south of the Decon/Access area. Site workers and oversight personnel willbe required to verify current health and safety training prior to entering the Decon/Accessarea or the active work areas of the site. The Decon/Access area will be marked by aperimeter orange plastic snow fence (3 feet in height).
All contaminated site materials being stored for off-site disposal will be drummed andmaintained within the Decon/Access area.
It is noted that vehicle inspection and any necessary vehicle cleaning/decontaminationprior to site exit will be completed in the northern portion of the Decon/Access area. Thisarea is the southern most area of the site currently identified for remediation (Grids AA13 and BB13 as seen on Figure 1). These grids will be the last site grids that will besubject to soil removal.
2.1.2 Silt Fence InstallationTo prevent potential transport via precipitation runoff of materials disturbed by the soilexcavation, silt fencing will be placed in the area indicated in Figure 1. These areasrepresent the topographic lows in the designated work area. These areas include thewestern and northern boundaries of the proposed excavation areas. This will requireapproximately 800 linear feet of silt fencing. Silt fencing will be in place prior to anyearth movement at the site and will remain in place until all site remediation activities aredetermined to be complete.
2.1.3 Debris StagingCurrently, building and equipment debris is present in several of the proposedremediation areas. This debris will be removed from the areas of the site requiring soilremoval and along access routes as necessary to provide a working area to complete thetasks outlined in this remediation plan. This debris will not be removed or disposed off-site. Debris from excavation areas surrounding the demolished site buildings (e.g.. theSouth and North Chemical Buildings) will be placed back on the foundation area of thosebuildings. Miscellaneous debris not necessarily associated with the demolition of formerbuildings will be collected in one or more staging areas to be established at the site (e.g.,within the covered sludge handling area and the paved adjacent drum storage area).
2.1.4 Brush RemovalBrush will be removed from the surface of the site and along access routes as necessary toprovide a working area to complete the tasks outlined in this removal plan. Cleared brush
Page 14
will be stored on-site and chipped for use as a surface cover after all soil removal hasbeen completed.
2.1.5 Establishment of Perimeter Air Monitoring LocationsFour perimeter air monitoring stations will be established around active work areas of thesite for the purpose of monitoring airborne dust levels. The proposed location of thesestations is shown on Figure 1. The specific airborne dust monitoring to be completed atthese stations is summarized in Appendix E.
2.2 Phase II Tasks — Soil Excavation and StagingCurrently, the soil removal is scoped as a phased process which will include excavation, finalcharacterization, and off-site transport and disposal. That process is outlined below. It is notedthat it may be possible to directly excavate and dispose of some soils (without staging/pre-disposal sampling). Direct disposal of any soils based on existing data would be in part at theapproval of the disposal facilities (as yet to be determined). Should such an alteration beapproved by the disposal facilities, an amendment to this plan will be submitted and prepared.
2.2.1 Soil ExcavationSoils will be excavated to a depth of approximately two feet in all areas of the siteindicated on Figure 1. The exception to this excavation depth are the areas of Kl 1, R16,and R12 where deeper excavations will be completed to address the higher concentrationof either lead or Aroclor 1248 found in these locations beneath the two foot level. Theactual depth of the excavations in the Kl 1 and R16 areas is expected to be 3 feet whilethe depth of excavation in the R12 area requires further definition which will becompleted prior and during the excavation work.
The soil excavation will be completed by a smooth bladed excavator, with excavated soilsplaced in temporary stockpiles within the excavation area. Soils will be stockpiled inapproximately 200 yard increments, which will be approximately the equivalent of four25 x 25 foot remediation areas over most of the site. The stockpiles will be constructedin areas designated for removal (on top of soil earmarked for removal). Stockpiles willbe no greater than ten feet in height. Following excavation, the excavated soils will becovered with polyethylene in such a way as to prevent precipitation contact or airbornedust generation from the excavated materials. Soil will be temporarily stored untilcharacterized and approved for off-site disposal.
To aid in gauging the two foot removal depth, the elevations of each grid corner withinthe proposed remediation area were measured by a certified land surveying firm. Thiswork was completed as a part of the pre-design investigation. The elevations of each gridcorner are presented in Appendix C. Where the surface topography varies significantlywithin a 25 by 25 foot grid, additional surface elevations within each grid will bemeasured prior to the soil removal activities. Following all soil removal within a gridlocation, final elevations will be surveyed to record the depth of native soils and verifythe depth of removal at that location.
Page 15
Given the nature of the site, it is possible that subsurface piping or other obstructions maybe present in one or more of the excavation areas. If subsurface piping is encounteredduring the shallow excavations, the piping will not be disturbed and excavations willcontinue around the piping. Soils around the piping will be hand dug and transported tothe appropriate stockpile. Should subsurface piping be inadvertently broken during soilexcavation, this piping will be segregated in a separate polyethylene lined staging areas.Should a minor release of liquid or solid materials from an underground pipe occur, theaffected soils will be excavated and placed separately on polyethylene and covered foradditional characterization prior to off-site disposal. Any significant release would behandled as release incident. At such a time, all site work will cease and the incident willbe handled according to appropriate immediate response activities listed in the HASP.
Other large subsurface features (such as former foundations) will be left in place. Soilsfrom around these features will be removed by hand digging.
An exception to the soil excavation and staging methodology will be implemented in thelocation of grids Q16, Q15, R16 and R15. In this location, surface soil PCB impact wasseen to be near or hi excess of 50 ppm. Because the 50 ppm concentration is a triggerlevel requiring segregation of such material and disposal by an alternate means, in thesegrids, two stockpiles will be created. The first will be from the 0 to 1 foot depth and thesecond will be from the 1 to 2 foot depth. Each pile will be separately characterized forpossible disposal at two different off-site facilities. A similar segregation of soils mayalso be completed in other areas of the site (e.g., around Grid R12) where Aroclorconcentrations may be at or near 50 ppm.
The surface soil excavation/staging will proceed first with the areas on the northern sideof the site, then proceed to the area west of the North and South Chemical Buildings, andfinally will proceed to the soils at the center of the site. The final soils to excavated andremoved from the site will be in the AA13 and BB13 grids which mark the northernextent of the decon/access area.
Lastly, based on the permeability of the surface and near surface soils andCompliance, Inc.'s past observations of the site during significant rain events,significant lateral precipitation flow during the excavation work is unlikely.Nonetheless, the temporary soil piles will be placed in locations designed to limit thepotential for the lateral conveyance of precipitation across the site. The placementof the temporary piles will also be supplemented, if necessary, with the constructionof temporary one foot soil berms within the excavation areas to accomplish this goal.
2.2.2 Staging of Drummed SoilsNumerous drums, potentially soil containing, are located in the staging area of the site.According to U.S. EPA. any soils remaining in these drums likely originated fromsubsurface borings (e.g.. on and off-site monitoring well installations). According to U.S.
Page 16
EPA., the drummed soils would not contain materials that would be inconsistent with theoff-site disposal strategy outlined herein.
The tops of each drum will be opened and any drums determined to contain soils will betransported to the staging area established in the K16 remediation area. The soils will beconsolidated with the surface soil stockpile in this location.
Any drums containing liquids will be immediately resealed and labeled with markingpaint as "Liquid". Handling and disposal of liquid containing drums is outside of thescope of this soil remediation design.
2.2 J Provisions for Dust ControlA water filled tank truck will be maintained on-site during all work periods for thepurpose of providing dust control. Dust control will be implemented at the direction ofthe Compliance, Inc. Project Manager. Any decision to implement dust control will bemade based on either visual observations of dust from the active work areas and/or dustmonitoring results above established action levels. Should a decision to undertake dustcontrol measures be made, all removal/disposal activities will cease until dustsuppression is appropriately completed. Decisions to resume work following stoppagefor dust suppression will be made by the Compliance, Inc. Project Manager.
Additionally, while the RI and the pre-design investigations did not reveal likely ambientair VOC or odor issues, if significant chemical odors are observed in the work area, workwill be stopped and both characterization sampling and odor control activities will beimplemented. Characterization sampling will initially include field screening of ambientair using a photoionization detector. Should readings greater than 5 ppm abovebackground be observed in the work area, work will be halted until ambient readingsreturn below 5 ppm or until characterization sampling is completed to ensure that higherlevel PPE is not warranted. Any work completed while ambient air VOC concentrationspersist above 5 ppm will require Level C or higher PPE.
2.3 Stockpiled Soils CharacterizationIn addition to the previously collected data, soil characterization for off-site disposal approvalpurposes, will require the collection and analysis of additional soils samples of the excavatedmaterial. The scope of all sampling will be determined in part by the off-site disposal facility.For the purposes of this design, it is assumed that one composite soil sample from each 200 yardstockpile will be collected. Soil samples will be collected as a composite of four pile surface andfour pile subsurface areas. The subsurface samples will be collected by hand auger from two tothree feet beneath the pile surface. The composited soil sample will be placed in appropriatesample containers and analyzed according to QAPP approved methods by the QAPP selectedanalytical laboratory. Alternatively, if directed by the off-site disposal facility, otherlaboratories/analytical methods for characterization prior to off-site disposal may be used.
Page 17
It is anticipated that the soil characterization step will require an approximate 10 day time periodfor analytical turn-around and final disposal facility approval. During this time period, dailychecks of the site will be completed to verify that all stockpiled materials remain appropriatelycovered and dust generation is prevented. These checks will be made seven days a week.
2.4 Off-site Transport of SoilsAfter analytical data and disposal approval for each pile is received, the soils will be loaded ontoDOT approved hazardous waste hauling vehicles for off-site for final disposal. Each shipmentwill be covered and inspected prior to exiting the site. Each load will be properly manifested andcopies of each manifest will be maintained by the Compliance, Inc. project manager. Eachshipment will be weighed upon exit at a local truck scale.
Entrance and egress for all waste hauling vehicles will be made via Viaduct Street traveling toand from the west, connecting to/from Sanford Avenue and then to/from 28th Street west of thesite. Vehicles will make access/egress via 1-196 and travel to the selected soil disposal facility.This vehicle route has been selected to limit travel near residential neighborhoods.
It is anticipated that six to ten waste hauling vehicles will be utilized in the off-site disposal ofthese wastes. At a maximum rate of 1.5 round trips to the selected disposal facility per day, amaximum of 15 vehicle passages through this route would be expected to occur per day. At thisrate of transport, complete off-site shipment will require approximately three weeks toaccomplish.
Depending on final characterization results, materials may be disposed at more than oneregulated disposal facility. The disposal facility will be selected and approved jointly by bothTPI and the selected removal contractor. The U.S. EPA and the MDEQ will be notified of theselected disposal facility at least 21-days prior to the first off-site shipment of soil.
2.5 Verification SamplingThe soils from the bottom of each excavation area will be sampled after soil removal inaccordance with the MDEQ Guidance Document "Verification of Soil Remediation" April 1994.Revision 1. The specific number of samples to be collected will be based on the Medium andLarge Site Soil Cleanup methodologies presented in that guidance. This will include theestablishment of a soil verification sampling grid system at the site calculated according to theVSR recommended formula. At an estimated 50 grid remediation, the total remediation surfacearea would be approximately 31,250 square feet (50 x 25 feet by 25 feet). According to the VSR,this would be a medium sized site and the verification sampling grid interval would be calculatedaccording to the following formula:
(A/;i)05/4
Where A = the surface area of the remediation area.
Page 18
At 31,250 square feet, the grid size would be approximately 25 feet (which is, coincidentally.equivalent to the 25 foot grid size selected for this remediation design). A gridding system ofthis size would be superimposed over the remediation area. Per the VSR guidance, once theappropriate grid is established over the remediation area, a phased subset of all samplinglocations may be chosen. This phasing acknowledges that a subset of the 50 sampling points(e.g., 25) may be sufficient to conclude that the soil removal has been appropriately completed.Per the VSR guidance, any subset of the sampling grid used initially would include at least 25%of the sampling grid total.
Approximately two thirds of the verification samples will be collected immediately following theinitial stockpiling of soils. These initial samples will be collected from those parts of theremediation area not covered by the temporary stockpiles and not located in vehicle traffic areas.The remaining approximately one third of the verification samples will be collected after thestockpiles are removed and on-site vehicle traffic is completed.
2.6 Initial Evaluation of Verification Sampling DataThe soil verification sampling data will be initially input in the database of all remaining sitesoils to provide an initial evaluation of whether sufficient soils have been removed to achieve thesite remedial goals. This initial calculation will be completed to determine if final sitebackfilling and grading can proceed or whether additional soil removal in one or more areas ofthe site are necessary.
A letter report summarizing this initial data evaluation will be submitted to U.S.EPA and theMDEQ prior to use of the initial evaluation for guiding this decision.
2.7 Final Site GradingAfter all soils have been removed from the site, the site surface will be graded. Wheredepressions are left from the removal activities, clean fill material will be brought on-site tocomplete the site to a workable grade. As economically available and at the request of the OCIPRPs. fill material of the same or lower hydraulic conductivity as the soils removed will be usedfor fill.
It is noted, that it is not the goal of the grading/backfilling activities to replace all excavated soils.For instance, along the western property boundary, the removal will be completed along the
slope adjoining the Holnum Inc. property. Any filling at this location will be completed with theprimary goal of maintaining a stable bank on that part of the property noting the existing slopedown to the property boundary. To maintain the slope on the western side of the site, it isestimated that the final site grading will be supplemented with the placement of approximately150 yards of topsoil and reseeding to promote vegetative growth. Given the flatter grade and thenature of existing surface soil in other areas of the site the placement of topsoil will not becompleted in other areas of the site.
Page 19
3.0 EQUIPMENT DECONTAMINATIONAll equipment working in the excavation areas including excavators, backhoes and trucks will bedry-deconned prior to off-site transport. Dry-decontamination will include the physical removalof soils adhering to vehicle tires, tracks and excavation blades and buckets. This will beaccomplished with brushes/shovels that will remain in the decon area and be dedicated for thispurpose. The Compliance, Inc. Project Manager will be responsible for verifying appropriatedecontamination of all equipment leaving the site and for determining if an upgrade (e.g., to wetdeconning/power washing) is required for any field equipment.
If wet deconning/power washing is determined necessary, a plastic lined, bermed temporarydecontamination pad will be constructed in the decon/access area. This will be in the AA-13 andBB13 grid locations. Power washing will be completed on this temporary pad with alldecontamination water collected and drummed for off-site disposal.
Smaller removal equipment (e.g.. hand tools and shovels) will be stored in thedecontamination/access area and will be washed prior to transport off-site.
4.0 HEALTH AND SAFETYAll excavation and removal work will be completed according to the site-specific health andsafety plan prepared by Compliance, Inc. The health and safety plan identifies potential safetyand health related issues, presents steps necessary to reduce and mitigate potential health andsafety risks, and present procedures to verify that the precautions presented in the health andsafety plan are utilized during the field activities. Verification that on-site workers under TPI'sdirection have received and reviewed copies of the health and safety plan will be documented.
Additionally, transporters of sludge materials determined to be a RCRA or TSCA regulatedhazardous material will be required to complete this work according to applicable DOTregulations regarding transportation safety. Transporters will be required to have in place acontingency plan for transportation related accidents and emergencies prior to initiation of work.

DATA VALIDATION REPORT
DATA VALIDATION REPORT
Site name: Organic Chemical Inc.
Number and Type of Samples: 76 soil samples
Laboratory* Southwest Laboratories of Oklahoma
76 soil samples were collected over the period 05/07 to 5 '15,2001. All samples were shipped to SouthwestLaboratories of Oklahoma (SWLO). The laboratory recehed groups of samples over the period 05/8/2001 to5/17/2001. The samples were processed in four groups labeled SDG 46447. SDG 46448. SDG 46484. and SDB46546.
All samples were reported to have been received in good condition. Sample jars submitted in one cooler fromgroup SDG 46448 were received at a temperature of 12.8 Celsius, above the prescribed temperature of 4.0Celsius. Sample labels were intact on all jars. One labeling discrepancy was noted after receipt of analyticaldata. This was that sample SS-261 was entered and anahzed by SWLO as sample FD-261. This transcriptionhas been corrected on the data tables in Appendix A.
The samples were analyzed for a target list of three metals, six Semivolatiles and two pesticide/PCB analytes.All samples were analyzed according to methodologies presented in the Quality Assurance Project Planprepared for this work dated April 21, 2001.
