Subject Groundwater Assessment Former Coyne International Enterprises Corp Building Westmoreland District Wayne County West Virginia

Dear Mr Trocin

On behalf of the Wayne County Economic Development Authority (WCEDA) Triad

Engineering Inc conducted a focused groundwater assessment at the former Coyne

International Enterprises Corp building (Coyne Building) which is located at 1111 Vernon

Street Westmoreland District Wayne County West Virginia The following summarizes

field activities and analytical results of this assessment Figure 1 Site Location Map

illustrates the location of the site

On October 32008 five temporary groundwater hionitoring points were installed using a

direct-push technology sampling unit A groundwater sample was collected from each

monitoring point and analyzed by a WVDEP certified laboratory for VOC as per United

States Environmental Protection Agency (USEPA) method SW-8260B Three monitoring

points were installed in the area of groundwater monitoring well MW-5 between the Coyne

Building and the CSX Transportation inc rail line and two monitoring points were installed

to the immediate north of the CSX Transportation Inc rail line Groundwater was

encountered at a depth of approximately 30-feet below ground surface (bgs) Figure 2

MEMORANDUM

TO John Meeks Triad Engineering Inc

FROM Bruce Fishman

DATE September 82009

SUBJECT Evaluation of Potential Risks Associated with Vapor Intrijsion to Indoor Air Coyne Textile Services Facility - Huntington West Virginia

bull V bull bull bull

This memorandum presents a risk evaluation for potential risks associated with vapor intrusion to indoor air at the Coyne Textile Services Facility located in Huntington West Virginia (site) This evaluation was conducted according to West Virginia Department of Environmental Protection (WVDEP) and United States Environmental Protection Agency (USEPA) methodologies

DATA INCLUDED 1N THE EVALUATION

This evaluation includes three subslab vapor samples (VP-01 VP-02 and VP-03) collected from immediately beneath the floor of the existing site building Table 1 lists the subslab vapor samples included in this risk assessment Samples were analyzed for volatile organic compounds (VOCs) by USEPA Method TO-15 Complete analytical data for these samples are provided in Table A-1 of Appendix A

The analytical results of the subslab vapor samples were compared to the target shallow soil gas comparison values presented in Table 2c of the USEPA vapor intrusion guidance document (2002a) These companson values are generic soil gas screening values that are protective of indoor air for residential land uses and represent concentrations in-sliallow soil gas based on a target risk level of 1 x 10reg andor a hazard index of 1 The comparison is presented in Table 2

As indicated in Table 2 the following constituents are identified as contaminants of concern (COC) for the vapor intrusion to indoor air pathway 124-trimethylbenzene 12-dichloroethene (cis) chloroform methylene chloride tetrachloroethene and triehloroethene

ESTIMATION OF INDOOR AIR CONCENTRATIONS

The concentrations of COC in indoor air associated with vapor intrusion from subslab vapor were estimated using methodologies outlined in the Users Guide for Evaluating Subsurface Vapor Intrusion into Buildings (USEPA 2004) A transport factor (TF) is required that will relate the

constituent concentration in subslab vapor to the concentration in indoor air The TF is dependent on the diffusion coefficient and other properties that will affect the transfer of constituents into air such as distance from the source to tlie breathing zone soil properties and building properties A site-specific building size of 84000 square feet (Dolphin 2000) and a soil type of sandy loam were used in the calculation of TF The TF is determined using calculationsbased on the Johnson and Ettinger (1991) vapor intrusion model Details of the TF calculations are provided in Appendix B

Subslab vapor concentrations are converted to indoor air concentration by applying the TF as follows

Cja ^ Csubslab X I r

The TF for each COC along with the resulting concentrations of COC in indoor air are presented in Tables

EXPOSURE EVALUATION

Noncarcinogenic health effects are evaluated by calculating the average dose of a constituent over the course of the exposure period This dose is termed the Average Daily Dose (ADD) Potential carcinogenic health effects are evaluated in terms of an individuals theoretical increased risk of developing cancer over a lifetime Although the duration of exposure to a constituent release generally does not last for an entire lifetime constituent intake for carcinogens is estimated as the average dose over a human lifetime (70 years) This lifetime dose applies specifically to the evaluation of carcinogenic effects and is termed tine Lifetime Average Daily Dose (LADD) In a risk assessment the calculated ADD or LADD are estimated quantitatively using assurnptions about the duration frequency and magnitude of exposure experienced by each potential receptor and assumptions about the constituent properties that influence absorption

The quantitative estimation of constituent intake involves the incorporation of numerical assumptions for a variety of exposure parahneters Exposure assumptions used in these intake calculations are based on WVDEP (2001) or USEPA (1989 2002b) recommended values The factors and equation for inhalation of vplatiles is presented in Table 4 and described below

bull Inhalation Rate and Exposure Time WVDEP (2001) and USEPA (2002b) guidance recommend that an inhalation rate of 20 m day be used for workers For an exposure time of 8 hours (a typical workday) this results in an inhalation rate of 25 m hour

bull Exposure Frequency and Duration Default exposure factors for indoor workers are provided by WVDEP (2001) Exposure frequency for the worker is 5 days per week for 50 weeks a year or 250 days per year The exposure duration for these workers is 25 years which is the 95th percentile value ai cording to the Bureau of Labor Statistics (USEPA 1989)

bull Body Weight The default value for average body weight of an adult is 70 kg based on WVDEP (2001) and USEPA guidance (1989 2002b)

AR100289

Risk-Based Remedies


bull Averaging Time As described above the doses for noncarcinogenic health effects are averaged oyer the specific period of exposure for a given receptor Noncarcinogenic

averaging times are therefore calculated by multiplying the exposure duration for the receptor by 365 daysyear Carcinogenic health effects are calculated over a lifetime exposure so the value recommended by WVDEP (2001) and USEPA (2002b) for average lifetime 70 years was used for exposure duration The resulting carcinogenic averaging time is 25550 days

TOXICITY VALUES

Noncarcinogenic responses are evaluated numerically using parameters known as the hazard quotient (HQ) and hazard index (HI) the HQ is obtained by dividing the ADD for a constituent by the reference dose (RfD) Each dose calculation with a specific combination of constituent receptor and exposure pathway will have a distinct ADD and calculated HQ HQs associated with all constituents for a particular pathway are summed to yield the HI

In order to estimate the theoretical excess lifetime cancer risk the LADD of a constituent is multiplied by the cancer slope factor (CSF) For each pathway this calculation is carried out for each applicable constituent and the risks are summed to obtain the total potential risk due to that pathway

Toxicity values for each constituent are presented in Table 5 the toxicity values were obtained from the following sources

bull Integrated Risk Information System (IRIS) on-line database provided by USEPA (2009)

bull The USEPAs Provisional Peer-Reviewed Toxicity Values (PPRTV) as presented in the USEPA Regional Screening Tables (ORNL 2009)

bull Provisional value from the National Center for Environmental Assessnient (as per WVDEP)

bull The Agency for Toxic Substances and Disease Registrys (ATSDR) Minimal Risk Levels (MRLs ATSDR 2009) and

bull Value cited by USEPA Region 3 attributed to other sources (as per WVDEP)

RISK CHARACTERIZATION

Potential noncarcinogenic effects associated with exposure to COC at the site are estimated by comparing calculated intakes with the contaminant-specific RfDs The total HI was calculated by summing the individual HQs An HI value equal to or less than 1 indicates thatthelikelihopd of ah adverse noncancer effect would be negligible (USEPA 1989) An HI greater than 1 indicates that additional evaluation of the case is warranted

Theoretical excess lifetime cancer risks associated with exposure to COC from the site were calculated by comparing estimated intakes to constituent-specific CSFs Summed theoretical

Page 3 of 5

AR100290

Risk-Based Remedies


excess risks are calculated by combining constituent-specific risks The results may be compared with target benchrharks for acceptable risk Various demarcations of acceptable risk have been established by regulatory agencies WDEP (2001) presents a target cancer risk of 1 x 10 for nonresidential scenarios USEPA (1991) considers potential cancer risks in the range of 1 x 10reg to 1 X 10 to be acceptable

Constituent-specific results for the indoor worker are presented in Table 6 For the indoor worker exposed to COC in indoor air (vapor intrusion from subslab vapor) the total HI is 00081 and the potential cumulative cancer risk is 497 X 10reg

These results meet both WVDEP and USEPA benchmarks indicating that the site poses negligible potential for human health risk for indoor workers

CONCLUSIONS

The results of this focused risk evaluation indicate that potential risks associated with vapor intrusion exposure of indoor workers to constituents that may volatilize from subslab vapor are within the acceptable benchmarks established by WVDEP and USEPA No further evaluation of the vapor intrusion pathway is warranted for the site

CALCULATION OF TRANSPORT FACTORS USED TO ESTIMATE INDOOR AIR CONCENTRATIONS

AR100304

APPENDIX B

Calculation of Transport Factors Used to Estimate Indoor Air Concentrations

This appendix presents the methodology for calculating transport factors that are used to convert subslab

vapor concentrations to concentrations in indoor air 124-Trimethylbenzene 12-dichloroethene (cis)

chloroform methylene chloride tetrachloroethene and triehloroethene were identified as contaminants of

concern (COC) for potential vapor intrusion from subslab vapor associated with the Coyne Textile

Services Facility located in Huntington West Virginia (site) In this appendix the transport factors are

calculated to estimate the concentrations of COC in indoor air of the existing plant building located at the

site ~

Transport Factor for Indoor Air

The concentration of a constituent in indoor air (da) is proportional to the concentration of the constituent

in the subslab vapors immediately beneath the building foundation (ie subslab vapor concentration or

Csubsiab) The following equation is used to calculate da from Csubsiab

^ wja ~ ^subslab X I r

where

Cia = concentration of constituent in indoor air (mgm^) -

Csubsiab^ concentration of constituent in subslab vapors (mgm^) and

TF = transport factor from subslab vapors to indoor air

The transport factor (TF) is an infinite source attenuation coefficient andcan be calculated based on a

model developed by Johnson and Ettinger (1991) t he equation for calculating TF is as follows

(Deff X A B ) ( Q B X L T ) X expKQso i l X Lcrabk)(Dcrack X Acrack)]

exp[ (Qsoi l X Lcrack)(Dcrack X Acrack)] + (Deff X A B ) ( Q B X L T ) + (Deff X AB)(Qsoi l X L j ) X (exp [ (Qso i l X Lcrack)(Dcrack X Acrack)] - 1)

where

Deff = effective diffusion coefficient for vadose zone soil (cm^sec)

AB = area of enclosed space below grade (cm^)

QB = building ventilation rate (cm^sec)

LT = distance from contaminant source to building foundation (cm)

Qsoii = volumetric flow rate of vapors into the building (cm^sec)

Lcrack = foundatlon thickness (cm)

Dcrack = vapor diffusion coefficient through crack (cm^sec) and

Acrack = area of cracks through which vapors can pass (cm^)

AR100305

To solve this equation the USEPAs SG-ADV spreadsheet Version 31 most recently updated in

February 2004 was implemented A combination of site-specific factors and default values from the

Users Guide for Evaluating Subsurface Vapor Intrusion Into Buildings (USEPA 2004) were used as input

values in the model All input values are defined below and presented in Tables B-1-A through B-6-A

bull The initial subslab vapor concentration (Csubsiab) is the maximum detected concentration(in units

of ugm ) of samples VP-01 VP-02 and VP-03 that was presented in Table 3 of the report

bull The depth below grade to the bottom of the enclosed space floor (Lp) is set to 15 cm the default

value provided by USEPA (2004) for a slab-on-grade structure

bull The vapor sampling depth below grade (Lg) is a site-specific value The vapor samples were

collected from immediately beneath the building floor therefore Lj has been set to 15 cm

bull The average soilgroundwater temperature (Ts) is set to 125degC the average value for West

Virginia as estimated frorri Figure 8 of the vapor intrusion users guide (USEPA 2004)

bull The soil type used to estimate vapor permeability is assumed to be sandy loam (SL) The

associated soil properties for a sandy loam soil type are as follows the soil dry bulk density (Pb) is

162 gcm the total porosity (n) is 0387 (cm^-aircm^) and the water-filled porosity (nw) is 0103

(cm -HzOcm )

bull The floor thickness (Lcrack) is set to the USEPA (2004) default value of 10 cm

bull The soil-building pressure differential (AP) is set to the USEPA (2004) default value of 40 gcm-s^

bull The building dimensions are siterspecific based on the existing plant building located at the site

The existing structure is approximately 84000 square feet (Dolphin 2000) therefore the

dimensions are set to 8839 cm (290 feet) length by 8839 cm (290 feet) The USEPA (2004)

default value of 244 cm vyas used for the height

bull Thefloor-wall seam crack width (w) is set to the USEPA (2004)-default value of 01 cm

bull The indoor air exchange rate (ER) is set to 083hour This is the value provided by ASTM (2002)

for commercial and industrial buildings

AR100306

Tables B-1-B through B-6-B present the constituent-specific properties for COC that were used in the TF

calculations Tables B-1-C through B-6-C present the intermediate calculations used to determine the

indoor air attenuation coefficients (ie the transport factors) The shaded boxes in Tables B-1-C through

B-6-C also present the resulting TF values that are applied to the concentrations of COC in subslab

vapor and the estimated indoor air concentrations
