RE: Idaho Pole Company Site Bozeman, Montana – Report of Surface Soil Sampling June 2018

Dear Mr. Hoogerheide:

On behalf of the Idaho Pole Company (IPC) and BNSF Railway Company (BNSF),

Hydrometrics, Inc. has prepared this report of surface soil sampling conducted at the Idaho Pole

Site (Site) located in Bozeman, Montana. Surface soils were collected from four different areas

on the Site and analyzed for dioxins as requested by the United States Environmental Protection

Agency (USEPA) in support of deleting the soils portion of the site. The sample locations

include the clean soil cap on the Treated Soil Area (TSA) south of Cedar Street, the former land

treatment unit (LTU) area, the former round house area and an off-site area north of I-90 as

shown on Figure 1. Sample collection and laboratory analytical methods are included herein.

Description of Sample Areas

The TSA occupies approximately 4.5 acres of the Site south of I-90 in the pressure plant and

barkfill areas as shown on Figure 1. Following demolition of the Pressure Plant at the site in

1999, soils contaminated with wood treating fluids were removed from the pressure plant area

and the barkfill area and placed in an on-site LTU for biological treatment. Once these LTU

soils met Record of Decision (ROD) treatment goals for pentachlorophenol (PCP) and

polyaromatic hydrocarbons (PAHs), they were placed back in the pressure plant and barkfill pits

and covered with 12 to 15 inches of clean soil. The clean soil cover over the treated soil was

required to prevent direct contact risk (to human and ecological receptors) as the treated

(backfilled) soils do not allow for unlimited use/unrestricted exposure.

After all treated soil was removed from the LTU, the liner and underlying bedding materials

were removed and the site regraded. Prior to construction of the LTU, this area was used for

storage of white wood. This area has been an open field since LTU decommissioning in 2002.

The former roundhouse occupied part of the yard south of Cedar Street as shown on Figure 1.

The roundhouse was operated by BNSF and had included a turntable for steam locomotives.

Only portions of the foundation of this structure remained at the time the Remedial Investigation

was conducted at the site (MSE, 1992).

The off-site area north of I-90 selected for sampling is currently owned by IPC and was part of

the Simmons residence. No wood treating operations or remediation activities have occurred on

this parcel. Three monitoring wells currently do exist on this parcel and include 27-A, 27-B and

GM-8. The property has most recently been used for horse pasture.

Methodology

On June 12, 2018, one five-point composite sample was collected from each of the four areas.

The five sub-sample locations (Figure 1) were selected by gridding each sample area and

randomly selecting coordinates prior to mobilizing to the field. The selected coordinates were

uploaded to a GPS device which was used to locate the sample sites in the field.

For each composite sample, the five sub-samples were collected from surface soils (0 – 6 inches

in depth) using a hand trowel. The sub-samples were thoroughly combined in a stainless steel

bowl before placing in a laboratory provided jar. All equipment coming into contact with soil

was decontaminated using a three-step process consisting of an Alconox™ /water solution wash,

5% acetone/water secondary rinse and a deionized water rinse between samples. The wash and

rinse water was disposed of on the ground surface. After the final decontamination procedure,

the second deionized water rinse was collected in laboratory supplied jars to create a rinsate

blank.

Sample containers were labeled and placed on ice before shipping to PACE Laboratory in

Minneapolis, Minnesota for analysis of dioxins by EPA Method 8290.

Results

The cleanup level of 1,000 nanograms/Kilogram (ng/Kg) for dioxin at the Site was established in

the ROD and is based on calculated toxicity equivalence (TEQ). The TEQ expresses the toxicity

of dioxins and furans in terms of the most toxic form of dioxin, 2,3,7,8-TCDD. To calculate the

TEQ, the concentration of each congener is multiplied by its assigned toxicity equivalent factor

(TEF), which is multiplied by the concentration for that congener. If a concentration is below

the detection limit, then ½ of the detection limit is used as the concentration. These products are

summed for the 17 congeners resulting in the single TEQ. The laboratory calculated the TEQ for

each sample using TEFs adopted by the World Health Organization (WHO, 2005).

TEFs calculated for the four composite surface soil samples ranged from 12 ng/Kg to 570 ng/Kg,

all below the ROD clean up level. The laboratory report is attached and the results by area are as

follows:

Former Roundhouse Area sample (IPC-SS-RHS) = 570 ng/Kg;

TSA sample (IPC-SS-TSA) = 190 ng/Kg;

Former LTU Area sample (IPC-SS-LTU) = 20 ng/Kg; and

Residential Area sample (IPC-SS-RES) = 12 ng/Kg.

https://en.wikipedia.org/wiki/Polychlorinated_dibenzofurans

https://en.wikipedia.org/wiki/2,3,7,8-TCDD


The laboratory reported a TEF of 31 picograms/liter in the rinsate blank sample (IPC-FB). Small

quantities of dioxins were also reported in the laboratory blank associated with this sample.

In 2008, the MDEQ completed a statewide effort to quantify background concentrations of

dioxins and dibenzofurans in surface soils in all regions of Montana. The TEF (12 ng/Kg) for

2,3,7,8 TCDD in the sample from the residential property near IPC was within the range of

values observed for rural and residential samples collected in Montana during the MDEQ study

(https://deq.mt.gov/Portals/112/Land/StateSuperfund/Documents/DioxinGuide/DioxinBackgroun

dStudy.pdf).

IPC looks forward to the USEPA moving forward with the soil deletion for the IPC site, given

the results of this surface soil sampling effort.

Please do not hesitate to contact Les Lonning or myself if you have any questions.

Sincerely,

REPORTOFLABORATORYANALYSIS

This report shall not be reproduced, except in full,

without the written consent of Pace Analytical Services, Inc.

This report presents the results from the analyses performed on five samples submitted by a representative of

Hydrometrics. The samples were analyzed for the presence or absence of polychlorodibenzo-p-dioxins (PCDDs)

and polychlorodibenzofurans (PCDFs) using a modified version of USEPA Method 8290. The reporting limits

were based on signal-to-noise measurements. Estimated Maximum Possible Concentration (EMPC) values were

treated as positives in the toxic equivalence calculations at one-half of the reported concentrations.

Second column confirmation analyses of 2,3,7,8-TCDF values obtained from the primary (DB5-MS) column are

performed only when specifically requested for a project and only when the values are above the concentration of

the lowest calibration standard. Typical resolution for this isomer using the DB5-MS column ranges from 25-30%.

The recoveries of the isotopically-labeled PCDD/PCDF internal standards in the sample extracts ranged from

36-72%. Except for twenty-seven low values, which were flagged "R" on the results tables, the labeled internal

standard recoveries obtained for this project were within the 40-135% target range specified in Method 8290.

Also, since the quantification of the native 2,3,7,8-substituted congeners was based on isotope dilution, the data

were automatically corrected for variation in recovery and accurate values were obtained.

Values were flagged "I" where incorrect isotope ratios were obtained. Concentrations below the calibration range

were flagged "J" and should be regarded as estimates. Concentrations above the calibration range were flagged

"E" and should also be regarded as estimates.

A laboratory method blank was prepared and analyzed with each sample batch as part of our routine quality

control procedures. The results show Blank-62960 to contain trace levels of selected congeners. These levels

were below the calibration range of the method. Sample levels similar to the corresponding blank levels were

flagged "B" on the results table and may be, at least partially, attributed to the background. It should be noted that

levels less than ten times the background are not generally considered to be statistically different from the

background.

Laboratory and matrix spike samples were prepared with the sample batches using clean reference matrix or

sample matrix that had been fortified with native standard materials. The results show that the spiked native

compounds were generally recovered at 102-127% with relative percent differences of 0.2-9.9%. The

background-subtracted recovery values obtained for OCDD in the matrix spike and matrix spike duplicate were

above the 70-130% target range, possibly due to the level of this congener in the sample material. Matrix spikes

were prepared with the water sample batch using sample material from a separate project; results from these

analyses will be provided upon request.
