This Technical Memorandum (TM) presents a human health, preliminary risk evaluation (PRE) for environmental media present in the Decision Units (DU) located at the American Creosote Works (ACW) Superfund site in Winnfield, Louisiana. The PRE is based on laboratory analysis of samples collected in February and March 2013. The PRE was performed as generally described in the U.S. Environmental Protection Agency (EPA) approved Work Plan Revision No. 2 American Creosote Works Superfund Site Remedial Investigation/Feasibility Study (CH2M HILL, 2012) (Task 7 of the scope). As noted in the work plan, a full risk assessment is being conducted only for the Former Process Area DU and the Creek DU. The information presented in this TM is expected to be used by EPA to determine whether a more comprehensive risk assessment for these DUs is warranted.

Preliminary Risk Evaluation Approach The PRE for each DU was calculated by dividing the maximum detected dioxin/furan and polycyclic aromatic hydrocarbon (PAH) concentrations, expressed in 2,3,7,8 tetrachlorodibenzo‐p‐dioxin (TCDD) toxicity equivalents (dioxin TEQ) and benzo(a)pyrene toxicity equivalents (BAP TEQ), by their corresponding residential and industrial exposure‐based regional screening levels (RSLs) (EPA, 2013), and multiplying the result by a target excess lifetime cancer risk (ELCR) of 1 x 10‐6. The screening comparison results are summarized in Tables 1A for residential scenario and Table 1B for industrial scenario with the detailed information presented in Risk Assessment Guidance for Superfund (RAGS) Part D Table 2 format for all DUs in the accompanying attachment.

As previously stated, a comprehensive quantitative risk assessment for the newly collected data is being conducted for the Former Process Area DU and the Creek DU; that assessment is being presented in the Risk Assessment Addendum (pending). All other DUs are being addressed through only the screening approach presented in the attachment. However, a PRE for residential scenario for soil, sediment, and surface water data from all the DUs (including the former Process Area DU and the Creek DU), and a PRE for industrial scenario for soil and sediment from all DUs are presented in this TM for comparison. A PRE for the groundwater medium was not performed because a majority of the groundwater data is from monitoring wells located within the former Process Area DU, and the adjacent Northern DU, which are included as part of the quantitative risk evaluation.

Role of Background in the Preliminary Risk Evaluation Background dioxin/furan and PAH concentrations were evaluated using laboratory analysis results for samples collected from the Background DU, as shown in Tables 2a and 2b of the attachment. These values were included in the DU‐specific Tables 2.1 to 2.16 of the attachment, and a detected chemical was identified as a chemical of

potential concern (COPC) only if it exceeded the background threshold value (BTV). The background dioxin TEQ and BAP TEQ concentrations are higher than their respective residential RSLs. The DU‐specific maximum‐detected dioxin TEQ and BAP TEQ concentrations were greater than their respective background values.

Preliminary Risk Evaluation Results Summary Tables 1A and 1B summarize the PRE estimates by media for each DU. The various DUs data screening in Tables 2.1 to 2.16 and background DU in Tables 2a and 2b, provided in the attachment, present the more detailed screening comparisons of the DU‐specific data against the background data, and the RSLs. The PREs indicate the following:

The residential scenario based total PRE (dioxin TEQ plus BAP TEQ) ELCR was above the upper bound of theComprehensive Environmental Response, Compensation and Liability Act (CERCLA) risk range of 1 in 1 millionto 1 in 10,000 (1x10‐6 to 1x10‐4) for all of the DUs in surface soil as well as subsurface soil, with the exceptionof subsurface soil PRE for Southern DU and the Tar Mat DU (see Table 1A), where the PRE lies within theCERCLA risk range. The industrial scenario based PRE was above the upper‐bound limit of the 1x10‐4 at 2 of theDUs, and nearly above the limit at Northern DU (see Table 1B).

The highest BAP TEQ concentrations of 59.1 milligram per kilogram (mg/kg) in surface soil and 296 mg/kg insubsurface soil occurred within the Process Area DU. The Non‐Process Area DU had the highest dioxin TEQconcentration of 14,634 nanogram per kilogram (ng/kg) in surface soil. Subsurface soil dioxin/furan samplingand analysis was not performed for any of the DUs.

The Non‐Process Area DU PRE is driven primarily by the presence dioxin/furans in surface soil, whereas in theother DUs, PAHs are the primary risk driver.

BAP TEQ constituents were detected in each of the creek sediment samples, including the backgroundlocations. PAH concentrations were highest in the north segment between the Process Area and NorthernDUs. The residential scenario based PRE for surface water and sediment is presented in Table 1A, and theindustrial scenario based PRE for sediment is presented in Table 1B for the Creek DU. A more suitableexposure scenario for the Creek DU is a recreational receptor. A quantitative risk evaluation for therecreational exposure scenario is presented in the Risk Assessment (Version 1.1) and Risk AssessmentAddendum.

The background soil samples had detectable dioxin/furan and PAH concentrations. The estimated background threshold values (BTVs) are included in Tables 1A and 1B. However, the concentration levels are lower than those detected in the various DUs. It is not known if the presence of these constituents is attributable to former ACW operations or other non‐point anthropogenic sources.

Overall, based on the PRE, a quantitative risk assessment is expected to be helpful with future risk management decisions for the remaining DUs. The quantitative risk assessment would evaluate the use of the maximum detected concentration versus a 95 percent upper confidence limit (UCL) in determining the exposure point concentration, evaluate pertinent exposure scenarios, and further assess background contribution to the total ELCR. Based on the direction provided by EPA, after a review of the information presented in this TM, the draft Human Health Risk Assessment Addendum report for the 2013 data will be finalized and submitted for review.

Preliminary Risk Evaluation Uncertainty Use of the maximum detected concentrations in the dioxin TEQ and BAP TEQ determination may overestimate potential exposure risk for both the residential and industrial scenarios, depending on the concentration distributions in a sample group across a DU. The statistical mean and the UCL on the mean values, which could be lower than the maximum detected concentration provide a more reasonable risk estimations particularly for PAHs. Conversely, if the data set is small and the concentration distribution is skewed, then the use of a 95 percent UCL could result in selecting the maximum detected concentration. Thus, the PREs presented in Tables 1A and 1B are considered to be conservatively estimated.

009528



The PREs presented in Tables 1A and 1B do not include contributions from other carcinogenic COPCs detected (such as naphthalene and pentachlorophenol) in samples collected from each DU. Therefore, risks may be underestimated where these COPCs are present. Additionally, a PRE was not performed for non‐carcinogenic COPCs because only a few non‐carcinogenic COPCs were detected in the samples. Therefore, not including the non‐carcinogenic COPC based PRE in this preliminary risk screening is not expected to alter the overall PRE outcome.

(1) Maximum concentration is used for screening. v = low estimate

COPC = chemical of potential concern(2) Refer to Table 2, Supplement A for the calculation of the soil background values. ARAR/TBC = Applicable or Relevant and Appropriate Requirement/

To Be Considered(3) Regional screening levels for industrial and residential soil (November 2013). Concentrations based on non-carcinogenic health effects are ca = carcinogenic

adjusted using HQ=0.1. csat = soil saturationThe SL for acenaphthene was used as the SL for acenaphthylene. nc = noncarcinogenicThe SL for pyrene was used as the SL for benzo(g,h,i)perylene. HEAST = Health Effects Assessment Summary TablesNo screening level is available for carbazole. The HEAST cancer slope factor has been withdrawn. HQ = hazard quotientThe SL for 'Cresol, m-' was used as the SL for 'Cresols, m&p'. HHRA = Human Health Risk AssessmentThe SL for anthracene was used as the SL for phenanthrene. NA = not availableSL for benzo(a)pyrene was used as the SL for total BAP TEQ. B = compound was detected in the associated blank so the result may be biased highThe SL for xylenes was used as the SL for m,p-Xylene (sum of isomers). J = compound was detected below the reporting limit in the sample

L = compound was detected above the Method Detection Limit (MDL) but below the (4) Rationale Codes Selection Reason: Above Screening Levels (ASL) Contract Required Quantitation Limit (CRQL)

Deletion Reason: Below Screening Level (BSL) BAP TEQ = benzo(a)pyrene toxic equivalentNo Toxicity Information (NTX) SL = screening level

SVOC = semi-volatile organic compound(5) Carcinogenic PAHs (benzo[a]pyrene, benzo[a]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene, chrysene, dibenz[a,h]anthracene, VOC = volatile organic compound

Notes:(1) Arithmetic mean was calculated using one‐half of the non‐detect results. J = compound was detected below the reporting limit in the sample(2) Composite samples were collected for dioxins/furans. Each decision unit (DU) was divided into sample units (SUs) of approximately L = compound was detected above the Method Detection Limit (MDL) but 2‐acre areas for the incremental composite sampling (ICS). One ICS sample was collected per SU using discrete sample locations within that below the Contract Required Quantitation Limit (CRQL) SU. A composite sample was also collected for each DU and was comprised of the SU samples from that DU. Only the SU composite samples were included in the 95/95 UTL calculation. The DU sample results are provided for comparison purposes.(3) EPA's ProUCL Software, version 5.0, was used to estimate the 95/95 UTL. If the data followed multiple distributions, the lowest UTL was selected.(4) The 95/95 UTL was selected as the BTV. Two times the arithmetic mean was used as the BTV if a 95/95 UTL could not be calculated. 95/95 UTL Basis Notes: (a) A 95/95 UTL was not calculated because there was only one detected value.BTV = background threshold value (b) Data do not follow a discernible distribution.Det = detected (c) Data appear Normal at 5% Significance Level.DL = detection limit (d) Data appear Lognormal at 5% Significance Level.DU = decision unitFOD = frequency of detectionMax = maximummg/kg = milligram per kilogramMin = minimumNC = not calculatedng/kg = nanogram per kilogramQual = qualifierSU = sample unitSVOC = semi‐volatile organic chemicalUTL = upper tolerance level
