1.0 INTRODUCTION AND PROJECT DESCRIPTION

1.1 Purpose and Objectives

The Facilities designation for various polygons within the ARWW&S OU was initially used as

an overarching category for regions where the Land Reclamation Evaluation System (LRES)

protocol and/or remedial logic may not have been appropriate or may require modifications

because of past or present activities within the specific area. Sampling was performed within

individual Facility areas, as permitted by landowner access, to better characterize smelter related

impacts and determine remedial requirements, as appropriate. The goal was to obtain sufficient

soils data to determine the extent and magnitude of soil arsenic concentrations in comparison to

the appropriate human health arsenic action levels. In some instances, sampling was proposed to

determine if Superfund obligations are present or whether designation of the area as No Further

Action is appropriate.

This facility was sampled under the Agency-approved Facilities Sampling and Analysis

memorandum and is located in Remedial Design Unit (RDU) 2 – Lost Creek of the Anaconda

Regional Water, Waste and Soils (ARWW&S) Operable Unit (OU) at the Anaconda Smelter

NPL site. This ISIR summarizes the Remedial Action Objectives (RAO’s), reviews data and

observations from current and previous investigations, evaluates the need for remedial action,

and identifies appropriate performance standards for Preliminary Land Remediation Unit

(PRLU) polygon LTCK-017.01 in accordance with the Record of Decision (ROD) (EPA, 1998)

and Final Vegetation Management Plan (VMP) (Atlantic Richfield, 2013) for the ARWW&S

OU.

1.2 Project Organization

Atlantic Richfield’s designated representative; TREC, Inc. in conjunction with EPA oversight

personnel was responsible for determining the location of the soil sample pits, performing the

excavation of the sample pits and collecting the soil samples. Prior to sampling activities,

appropriate landowners were contacted to facilitate access to the site. TREC reviewed the data

with respect to the remedial action requirements and developed this ISIR.

1.3 Site Description

LTCK-017.01 is a small privately owned gravel pit/disturbance located north of Lost Creek Road

that is approximately 0.7 acres in size (see the Facilities Vicinity Map provided in Figure 1).

Based on current land use, the recreational/open space/agricultural action level of 1,000 mg/kg

for surface soil arsenic is appropriate for areas within this facility. No previous sampling

locations existed within the facility. Therefore, one location was sampled under the Facility

Sampling and Analysis Memorandum to further characterize potential smelter related impacts at

the site and assist in evaluation of remedial requirements.

2.0 PROJECT ACTIVITIES

2.1 Description of Project Activities

Sampling locations under the Facilities Sampling and Analysis Memorandum were identified to

better characterize smelter related impacts and determine remedial requirements, as appropriate.

All sample pits were excavated by hand. The sample crew typically consisted of a 2 person crew

accompanied by an Agency representative. All field data and analytical samples were collected

as directed by the Facilities Sampling and Analysis Memorandum and documented in the Field

Log book. Upon the end of each sampling day, the sample crew would complete the Chain-of-

Custodies for the samples. The samples were then delivered to the laboratories within a few

days following sample collection. After samples were collected, each test pit was backfilled by

hand but not reseeded. Care was taken during all phases of the sampling effort to minimize

damage to the existing vegetation.

2.2 Sample Location Documentation

2.2.1 Sample Labeling

Sample locations were labeled by location and depth interval according to the list provided in the

Facilities Sampling and Analysis Memorandum. Depth intervals were labeled as follows:

0 to 2 inches (A interval; surface sample);

2 to 6 inches (B interval);

0 to 6 inches (C interval); and

6 to 12 inches (D interval).

Location labels generally followed the format of FAC for Facilities sampling followed by a two

digit year identifier indicating the year sampled followed by a sequential number. An example

of a sample label is as follows (FAC-10-101A). Figure 2 shows the final locations of the sample

points overlaid on a basemap.

2.2.2 Field Documentation

A field log book was maintained during this sampling investigation. Copies of the field logs are

included as Appendix C. The original field log books for the facilities sampling event are

located in the offices of TREC, Inc. in Bozeman, Montana.

2.3 Analytical methodology

Table 2 presents the analytical methods used for sample analysis. Quantitative laboratory

measurements include arsenic, cadmium, copper, lead, zinc and pH for all samples. Table 2 of

the Facilities Sampling and Analysis Memorandum (Atlantic Richfield, 2010) provides

additional detail on the analytical method used for analysis of these parameters. All analyses are

consistent with the Clark Fork River Superfund Site Investigation Lab Analytical Protocols (CFR

SSI LAP) and Quality Assurance Project Plan (QAPP) (PTI, 1992b) unless otherwise noted.

2.4 SAP Deviations

pH samples were taken for the C-horizon (0-6 inches) and D horizon (6-12 inches) for each test

pit.

3.0 REMEDIAL ACTION OBJECTIVES AND REQUIREMENTS

Remedial requirements for impacted soils that are applicable to areas within the ARWW&S OU

are identified in the ROD and FDRs/RAWPs. Design criteria relevant to “facility” areas

identified in this plan include:

Reduce arsenic concentrations at the surface to below human health arsenic action levels

– 1,000 mg/kg for open space/agriculture/recreation, 500 mg/kg for commercial/

industrial areas, 250 mg/kg for residential areas and 2,500 mg/kg for steep slope areas in

Smelter Hill RDUs 3 and 14 where access restrictions are in place through Atlantic

Richfield ownership or restrictive covenants.

High arsenic area – In areas of good vegetation (i.e. Dutchman) or of beneficial use (i.e.

historic areas) that are owned by Atlantic Richfield or a government entity and exceed the

arsenic action level, implementation of ICs may be appropriate through management of

the area as a high arsenic area.

Additionally, evaluations of vegetation performance standards and monitoring and maintenance

(M&M) requirements are made based on land use pursuant to requirements identified in the Final

VMP for the ARWW&S OU (Atlantic Richfield, 2013), or the Modifying Criteria of the LRES

where standards under the VMP are inappropriate

4.0 SITE CHARACTERIZATION

4.1 Previous Investigations

No previous investigations were conducted for this site.

4.2 2010 Facility Sampling

Soils data for arsenic and other metals including, cadmium, copper, lead, and zinc were collected

to evaluate potential human health impacts as well as the potential impacts to vegetation

establishment. Sample data collected during the Facility sampling of polygon LTCK-017.01 are

presented in Table 1 below. Sampling locations are shown on Figure 2.

4.3 Analysis

As previously mentioned, Facility LTCK-017.01 represents a small privately owned former

gravel pit located north of Lost Creek Road. All of the data collected from the formal gravel pit

exhibited arsenic concentrations below the applicable recreational/open space/agricultural action

level of 1,000 mg/kg as well as the residential land use action level of 250 mg/kg. The Total

Metal Indices (TMI = As+Cu+Zn) for all sampled soils were also below the moderate plant

stress level of 1,700 mg/kg identified in the VMP and soil pH values were greater than 6.5

standard units and slightly alkaline. Therefore, no smelter related impacts were identified at the

facility requiring remediation.

4.4 Recommendations

No smelter related impacts were identified and therefore no active remedial requirements have

been determined necessary as a result of collecting and analyzing soils data for the facility

represented by polygon LTCK-017.01. Because soil arsenic concentrations are below the

residential land use action level of 250 mg/kg, this facility can be classified as Category 1

(Unrestricted Use) under the Final VMP.

Existing vegetation cover for this facility is generally sparse and in its current condition would

likely not pass the Operational and Functional (O&F) vegetation performance criteria identified

in the VMP for typical Category 1 properties. However, as discussed in the February 26, 2014

meeting between Atlantic Richfield and EPA representatives, application of LRES modifying

criteria is appropriate given physical site conditions and can be used to designate this facility as

NFA. Due to the absence of contaminated soils, the coarse nature of the existing soil surface

which effectively prevents fugitive dust generation, and most of the parcel having internal

drainage, the area will not have requirements for vegetation establishment or long-term

monitoring and maintenance (M&M) under Superfund.

Therefore, it is recommended that the facility represented by polygon LTCK-017.01 be

designated as a No Further Action (NFA) Category 1 (Unrestricted Use) area with no additional

Superfund obligations and unrestricted land use from a Superfund perspective. Future

development within this facility, however, will still be subject to all remaining and relevant

provisions of the ADLC Developmental Permit System (DPS) and other applicable federal, state,

and local laws as enforced by the ADLC.

Remedial activities identified in the RDU 2 - Lost Creek FDR/RAWP for areas immediately

adjacent to this facility consist of a T12 (tillage to 12 inches) remedy to the south of the facility

and SSR-2/SSR-3 (Steep Slope Reclamation types 2 and 3) to the north. These remedies will be

implemented up to margins of the LTCK-017.01 facility boundary during adjacent RA activities

as delineated during performance of the required pre-construction walkthrough with Agency

personnel. Weed management will also be performed within the margins of this facility in

conjunction with adjacent remediated areas, as appropriate.

*Field Duplicate

Design Justification Discussion: Facility LTCK-017.01 represents a privately owned former gravel pit that is located north of Lost Creek Road. All samples collected within the former gravel pit exhibited arsenic concentrations below the applicable recreational/open space/agricultural action level of 1,000 mg/kg as well as the residential action level of 250 mg/kg, and no other superfund impacts were identified. Therefore, this Facility is classified as a Category 1 (Unrestricted Use) area under the Final VMP and is designated as a NFA area using the LRES modifying criteria with no further requirements under Superfund.

REMEDY BASED ON EVALUATION OF BELOW DATA: No Further Action
