PRELIMINARY ASSESSMENTS AND SITE INSPECTIONS REPORT
UPPER COLUMBIA RIVER MINES AND MILLS
STEVENS COUNTY, WASHINGTON
1. INTRODUCTION
The United States Environmental Protection Agency (EPA) has tasked Ecology and
Environment, Inc. (E & E) to provide technical support in investigating potential sources of
contamination to the upper Columbia River project area. The upper Columbia River project area is
defined for this investigation as the portion of the Columbia River beginning at approximately river mile
(RM) 675 near Inchelium, Washington, extending upstream to the U.S.-Canada border at approximately
RM 745 (Figure 1-1). The Columbia River is the principal inflowto Lake Roosevelt and contributes
about 90 percent of the flow from a large drainage area in Canada and the United States (Figure 1-2).
Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) activities
conducted for this project included preliminary assessments (PAs) and site investigations (Sis) for
39 mine and mill sites in Stevens County, Washington (Figures 1-3 and 1-4). The PAs and Sis were
conducted under the authority of CERCLA of 1980 as amended by the Superfund Amendments and
Reauthorization Act of 1986. A list of the 39 mine and mill sites visited in Stevens County are presented
in Table 1 -1. Table 1-1 identifies mine and mill sites which the Confederated T ribes of the Colville
Reservation petitioned the EPA for assessment under CERCLA (Cawston 1999; Passmore 2000). The
remaining mine and mill sites listed in T able 1-1 were identified by the EPA based on the location of the
mine and/or mill relative to tributaries that empty into the upper Columbia River (project area) and
available information regarding volume of ore produced.
A detailed discussion of related field activities conducted at 21 mine and mill sites visited in
Pend Oreille County can be found in the Lower Pend Oreille River Mines and Mills Preliminary
Assessments and Site Investigations Report prepared by E & E for EPA, dated April 2002.
The PAs and Sis are phases in the site assessment process for determining whether a site has
released, is releasing, or has the potential to release, hazardous substances, pollutants, or contaminants
into the environment and whether it requires further detailed investigation and/or response action that is
authorized by CERCLA. The assessment process does not include extensive or complete site
characterization, contaminant fate determination, or quantitative risk assessment.
10:START-2\01020028\S759
1-1
-------
The objectives of the PAs and Sis are to:
Identify potential sources of contamination to the upper Columbia River project area;
Determine whether the mines or mills are releasing, or have the potential to release
hazardous constituents into the environment;
Document the threat or potential threat to public health or the environment posed by the
mines or mills;
Assess the need for additional detailed investigation and/or response action at the mines
or mills; and
Determine the potential for placement of each mine or mill on the National Priorities
List.
Field activities were conducted through a combined effort involving Superfund Technical
Assessment and Response Tearn (START)-2 contractor firms, E & E and Roy F. Weston, Inc.
(WESTON). Sampling activities were conducted at 18 of the 39 mine and mill sites visited in Stevens
County. E & E conducted sampling at mines and mills where potential sources of contamination were
identified and possible impacts to receptors via the surface water migration pathway were observed. In
addition, the soil exposure pathway was evaluated for the Deep Creek Mine and the LeRoi/Northport
Smelter. E & E activities were conducted under START-2 Contract No. 68-S0-01-01 andTechnical
Direction Document (TDD) No. 01-02-0028. WESTON collected sediment samples in tributaries to the
upper Columbia River and mine and mill-specific background samples as determined necessary by the
EPA. WESTON activities were conducted under START-2 Contract No. 68-S0-01-02 andTDD
No. 01-02-001-A.
Activities conducted as part of this investigation include reviewing existing mine and
mill-specific information, regional characteristics, collecting receptor information within the mine or
mill's range of influence, conducting visits to the mine and mill sites, executing the sampling plan, and
producing this report.
In accordance with the sampling and quality assurance plan (SQAP), attempts were made to
conduct in-situ field screening of metals concentrations at potential contaminant sources using X-ray
fluorescence (XRF) equipment. Due to field conditions, the instruments exceeded operating
temperatures on several occasions. It was determined that the equipment was not able to function
properly in a high temperature environment and its use was discontinued. A memo presenting the results
of the limited XRF screening conducted is included in Appendix D.

2. BACKGROUND
2.1 MINE/MILL OWNERSHIP
Property owners and/or representatives for the mines/mills visited are identified in Section 6.
Consent for access to each mine and mill sites visited was obtained prior to conducting the visits.
2.2 REGIONAL OPERATIONS AND WASTE CHARACTERISTICS
2.2.1 Historic Mining
The mining district surrounding the towns of Colville, Chewelah, Addy, and Northport in
Stevens County, Washington dates back to the 1880s (Battien 1998). Stevens County's Embry Camp is
the oldest mining district in the state. The Chewelah mining district was one of the earliest to be
discovered and put into production. Stevens County produced the most gold in the state of Washington
from 1905 to 1908 and again in 1922. The county led the state in the number of producing mines in
1928. By 1962, a geological survey stated that Stevens County produced half of the minerals of the state
of Washington. (Battien 1998)

3. Mi l l) ACTIVITIES AND ANALYTICAL PROTOCOL
A SQAP for the upper Columbia River PAs and Sis was developed by the START-2 prior to
performing the field sampling (E & E 2001). The SQAP describes the sampling strategy, sampling
methodology, and analytical program used to identify potential hazardous substance source areas and
impacts to potential targets. With few exceptions, field activities were conducted in accordance with the
approved SQAP. Deviations from the SQAP are described when applicable. Field activities were
conducted in coordination with United States Department of the Interior Bureau of Land Management,
United States Department of Agriculture Forest Service, and Washington State Department of Ecology
(Ecology) staff.
The field event was conducted from June 17 to 30 and September 9 to 15, 2001. Sampling was
conducted at 18 of the 39 mines and mills visited. Sampling was conducted at those mines and mills
where potential sources of contamination were identified and where possible impacts to receptors via the
surface water migration pathway were observed. In addition, the soil exposure pathway was evaluated
for the Deep Creek Mine and the LeRoi/Northport Smelter. Possible receptors of contamination that
were identified were also sampled.
As described in the SQAP, potential contaminant sources may include tailings piles/ponds, waste
rock piles, adits, and stained soil areas surrounding improperly stored or disposed drums and containers.
Potential receptors/targets may include wetland areas, fisheries, surface water intakes, sensitive
environments, etc. as defined in the EPA Hazard Ranking System (HRS); Final Rule. The contaminants
of concern (COCs) include T arget Analyte List (T AL) metals, chlorinated pesticide/poly chlorinated
biphenyls (pesticide/PCBs), and semivolatile organic compounds (SVOCs). Total organic carbon (TOC)
data was also collected for sediment samples.
A total of 203 soil/sediment samples and 13 surface water samples were collected by E & E and
analyzed under the EPA Contract Laboratory Program (CLP) for TAL metals. Sixty-eight soil/sediment
and two surface water samples were also analyzed under the EPA CLP for pesticide/PCBs. Thirty-
four soil/sediment and two surface water samples, were analyzed for SVOCs. A total of 20 sediment
samples were submitted to a commercial laboratory for TOC analysis. WESTON collected a total of
10:START-2\01020028\S759
3-1
-------
120 sediment samples and 5 surface water samples. Table 3-1 provides a summary of sample collection
information.
Sample types and the methods of collection are described below. A discussion of sample results
is contained in Sections 6 and 7. Photographic documentation of the PAs and Sis field activities are
contained in Appendix A.
Information pertinent to WESTON's related sampling activities involving the collection of mine
and mill-specific background samples is included in Appendix H.
3.1 SAMPLING MEfflO DO LOGY
Sampling for surface soil, surface water, and sediment followed the standard operating
procedures contained in Appendix A of the SQAP (E & E 2001). Grass, leaves and other vegetative
material, rocks and other debris unsuitable for analysis were removed from soil samples before being
placed into the sampling containers. Surface soil and sediment samples were homogenized in dedicated
plastic bowls (except for pesticide/PCBs analysis) prior to placement in sample jars. Dedicated plastic
spoons and scoops were used to extract, homogenize, and place sample material into sample containers
(except for pesticide/PCBs analysis). Dedicated steel bowls and steel spoons were used for the collection
and homogenization of pesticide/PCBs samples.
Water samples were collected by hand dipping a 1-liter polyethylene bottle sample container into
the water at well-mixed locations within the stream, or by using an unused sample container as a scoop to
obtain water samples in areas of low flow. An aliquot of each sample was tested in the field for
temperature and pH. After preservation, pH was checked again to ensure that the appropriate pH level
had been achieved.
All samples were stored on ice in coolers continuously maintained under chain-of-custody.
Vehicles were locked if the sampling team had to walk out of visual range. Sample coolers from all
teams were moved into a single occupied location (motel room) each evening to ensure custody control
and to re-ice as needed.
3.1.1 EPA CLP Surface Soil Samples
A total of 159 surface soil samples, including 9 background samples, were collected. Soil
samples were discrete grab samples collected from potential source and background areas. Surface soil
samples were collected from 0 to 6 inches below ground surface (bgs). Samples were analyzed for T AL
10:START-2\01020028\S759
3-2
-------
metals. A portion of samples also were analyzed for pesticide/PCBs (42 samples) and SVOCs
(12 samples).
3.1.2 EPA CLP Sediment Samples
A total of 44 sediment samples, including 9 background samples, were collected as outlined in
the text of the SQAP (E & E 2001). Sediment samples were collected from below the apparent water line
from 0 to 8 inches below the sediment surface in order from most downstream locations to most upstream
locations. Samples were analyzed for T AL metals. Twenty-six samples also were analyzed for
pesticide/PCBs, SVOCs (22 samples), andTOC (20 samples).
3.1.3 EPA CLP Surface Water Samples
A total of 13 surface water samples were collected prior to collecting co-located sediment
samples and from the most downstream locations to the most upstream locations. Water samples were
analyzed for TAL metals. A portion of samples also were analyzed for pesticide/PCBs (two samples)
and SVOCs (two samples).
3.2 ANALYTICAL PRO TO COLS
All samples collected were shipped off-site for chemical analysis, with the exception of field
measurement for pH. Analytical methods applied to E & E samples consisted of: EPA CLP TAL metals,
EPA CLP pesticide/PCBs, EPA CLP SVOCs, and EPA SW-846 TOC. These analyses were applied to
samples collected from suspected sources or targets in varying combinations based on the SQAP.
Laboratories performing the analyses are noted in Section 4. Analysis applied to mine and mill-specific
background samples collected by WEST ON were based on the approved SQAP; Upper Columbia
River/Lake Roosevelt Expanded Site Inspection Sampling and Quality Assurance Plan, TDD
No. 01-02-0001-A, EPA Contract: 68-S0-01-02, prepared for the EPA Region 10 by WESTON,
May 2001.
3.3 GLOBAL POSITIONING SYSTEM
Trimble Pathfinder Professional XL GPS survey units and data loggers were used by the
START-2 to approximate the horizontal location coordinates of sample points. Except as noted for
specific sample locations, the units provided three-dimensional differentially-corrected sample
coordinates with ± 1 meter accuracy. Due to the combination of the mountainous terrain and limited
10:START-2\01020028\S759
3-3
-------
satellite coverage over this area, the GPS units were often operating in no more than two-dimensional
mode.
Sample coordinates were plotted onto a digitized map and then incorporated into geographic
information system databases to develop a station/sample location map. The ST ART-2 was not able to
obtain accurate GPS coordinates at some locations due to mountainous terrain. These station locations
were estimated on the sample location map based on field observations. GPS coordinates by sample
point are provided in Appendix C. WEST ON GPS coordinates are found in Appendix H.
3.4 INVESTIGATION-DERIVED WASTE
Investigation-derived waste (IDW) generated during the sampling effort consisted of used
personal protective clothing and disposable sampling equipment. IDW was disposed of as non-hazardous
solid waste at a municipal landfill. No IDW generated by the ST ART-2 remains in the project area.

4. QUALITY ASSURANCE/QUALITY CONTROL
QA/QC data are necessary to determine precision and accuracy and to demonstrate the absence
of interferences and/or contamination of sampling equipment, glassware, and reagents. Specific QC
requirements for laboratory analyses are incorporated in the Contract Laboratory Program Statement of
Work for Organic Analyses (EPA 1999) and in the Contract Laboratory Program Statement of Work for
Inorganic Analyses (EPA 2000b). These QC requirements or equivalent requirements found in the
analytical methods were followed for analytical work on the upper Columbia River Mines and Mills PAs
and Sis project. This section describes the QA/QC measures taken and provides an evaluation of the
usability of data presented in this report. The QA/QC data memorandums regarding the samples
collected by WESTON can be found in the Upper Columbia River/Lake Roosevelt Expanded Site
Inspection Sampling and Quality Assurance Plan, TDD: 01-02-0001-A, EPA Contract: 68-S0-01-02.
Prepared for the EPA Region 10 by WESTON, May 2001.
All samples were collected following the guidance of the SQAP (E & E 2001) and the Sample
Plan Alteration Forms for the field activities. Soil and water TAL metals analyses were performed at
Sentinel, Inc., Huntsville, Alabama, a CLP laboratory, following CLP statement of work (SOW)
ILM04.1. Soil SVOC and pesticide/PCBs analyses were performed at the EPA's Manchester
Environmental Laboratory, Port Orchard, Washington, following EPA SW-846 Methods 8270
(SVOC analysis) and 8081/8082 (pesticide/PCBs analysis). Soil and water pesticide/PCBs analyses were
performed at Envirosystems, Inc., Columbia, Maryland, a CLP laboratory, following CLP SOW
OLM04.2. Soil and water SVOC and pesticide/PCBs analyses were performed at Mitkem Corporation,
Warwick, Rhode Island, a CLP laboratory, following CLP SOW OLM04.2. Soil SVOC and
pesticide/PCBs analyses were performed at Laucks Testing Laboratories, Inc., Seattle, Washington, a
CLP laboratory, following CLP SOW OLM04.2. Sediment TOC analyses were performed by the E & E,
Analytical Services Center, Lancaster, New York, a START-subcontracted commercial laboratory,
following the Lloyd Kahn method. Soil field screening for copper, lead, and zinc was performed in the
field by Environmental Services Assistance Team (ESAT) personnel following ESAT guidelines.
10:START-2\01020028\S759
4-1
-------
Data from the CLP laboratories were reviewed and validated by EPA and/or ESAT chemists.
Data from the ST ART -subcontracted commercial laboratory were reviewed and validated by E & E
chemists. Data qualifiers were applied as necessary according to the following guidance:
EPA (1990) Quality Assurance/Quality Control Guidance for Removal Activities,
Sampling QA/QC Plan and Data Validation Procedures;
EPA (1994a) Contract Laboratory Program National Functional Guidelines for
Inorganic Data Review; and
EPA (1999a) Contract Laboratory Program National Functional Guidelines for Organic
Data Review.
In the absence of other QC guidance, method-specific QC limits were also utilized to apply
qualifiers to the data. Copies of the data QA memoranda are included in Appendix D.
4.1 SATISFACTION OF DATA QUALITY OBJECTIVES
The following EPA (1994b) guidance document was used to establish data quality objectives
(DQOs) for this project:
Data Quality Objectives Process for Superfund, Interim Final Guidance, EPA
600-R-96-055.
The EPA Task Monitor (TM) determined that definitive data without error and bias
determination would be used for the sampling and analyses conducted during the field activities. The
data quality achieved during the fieldwork produced sufficient data that meets the DQOs stated in the
SQAP (E & E 2001). A detailed discussion of accomplished project objectives is presented in the
following sections.
4.2 QUALITY ASSURANCE/QUALITY CONTROL SAMPLES
QA samples included rinsate blank samples. Trip blank samples were not collected as volatile
organic compound analyses were not performed. Rinsate blank samples collected from sample collection
equipment were submitted for the project. QC samples included matrix spike/matrix spike duplicate
(MS/MSD) samples for organic analyses or MS/duplicate samples for inorganic analyses at a rate of one
MS/MSD or one MS/duplicate per 20 samples per matrix.
10:START-2\01020028\S759
4-2
-------
4.3 PROJECT-SPECIFIC DATA QUALITY OBJECTIVES
The laboratory data were reviewed to ensure that DQOs for the project were met. The following
describes the laboratories' abilities to meet project DQOs for precision, accuracy, and completeness and
the field team's ability to meet project DQOs for representativeness and comparability. The laboratories
and the field team were able to meet DQOs for the project.
4.3.1 Precision
Precision measures the reproducibility of the sampling and analytical methodology. Laboratory
and field precision is defined as the relative percent difference (RPD) between duplicate sample analyses.
The laboratory duplicate samples or MS/MSD samples measure the precision of the analytical method.
The RPD values were reviewed for all commercial laboratory samples. A total of 161 sample
results (approximately 1.5% of the data) were qualified as estimated quantities (J or UJ) based on
laboratory duplicate QC outliers. The DQO for precision of 85% was met.
4.3.2 Accuracy
Accuracy measures the reproducibility of the sampling and analytical methodology. Laboratory
accuracy is defined as the surrogate spike percent recovery (%R) for each SVOC or pesticide/PCBs
analysis or the MS %Rs for all fixed laboratory analyses. The surrogate %R values were reviewed for all
appropriate sample analyses. No sample results were qualified based on surrogate QC outliers.
The MS %R values were reviewed for all MS/MSD analyses. A total of 463 sample results
(approximately 4.4% of the data) were qualified as estimated quantities (J) based on spike QC outliers.
A total of 161 sample results (approximately 1.5% of the data) were rejected (R) based on spike QC
outliers. Overall, the project DQO for accuracy of 85% was met.
4.3.3 Completeness
Data completeness is defined as the percentage of usable data (usable data divided by the total
possible data). All laboratory data were reviewed for data validation and usability. A total of 29 sample
results (approximately 0.2% of the data) were rejected (R), therefore the project DQO for completeness
of 90% was met.
10:START-2\01020028\S759
4-3
-------
4.3.4 Representativeness
Data representativeness expresses the degree to which sample data accurately and precisely
represent a characteristic of a population, parameter variations at a sampling point, or environmental
condition. The number and selection of samples were determined in the field to account accurately for
site variations and sample matrices. The DQO for representativeness of 85% was met.
4.3.5 Comparability
Comparability is a qualitative parameter expressing the confidence with which one data set can
be compared to another. Data produced for this site followed applicable field sampling techniques and
specific analytical methodology. The DQO for comparability was met.
4.4 LABORATORY QUALITY ASSURANCE/QUALITY CONTROL PARAMETERS
The laboratory data also were reviewed for holding times and laboratory blank samples. These
QA/QC parameters are summarized below. In general, the laboratory and field QA/QC parameters were
considered acceptable.
4.4.1 Holding Times
A total of 4 sample results (approximately 0.04% of the data) were qualified as estimated
quantities (J or UJ) based on holding time outliers.
4.4.2 Laboratory Blanks
All laboratory blanks met the frequency criteria. The following potential COCs were detected in
the laboratory blanks resulting in qualifications:
SVOCs: bis(2-ethylhexyl)phthalate; and
TAL Metals: aluminum, antimony, arsenic, barium, beryllium, cadmium, calcium, chromium,
cobalt, copper, iron, lead, magnesium, manganese, nickel, potassium, selenium,
sodium, silver, thallium, vanadium, and zinc.
Four SVOC results and 361 TAL metals results were qualified based on laboratory blank
contamination. Associated sample results less than five times positive blank contamination (10 times for
common laboratory contaminants) were qualified as not detected (U). Associated sample results less
10:START-2\01020028\S759
4-4
-------
than five times the absolute value of negative TAL metals blank contamination were qualified as
estimated quantities (J or UJ). Two TOC results were also qualified as not detected (U) based on
laboratory blank contamination. See Appendix D for results that were qualified based on laboratory
blank contamination.

5. ANALYTICAL RESULTS REPORTING AND BACKGROUND SAMPLES
This section describes the reporting criteria and reporting methods applied to EPA CLP
analytical results presented in Sections 6 and 7 of this report. A discussion of background sample
locations and results also is provided. A list of all samples collected for laboratory analysis is presented
in T able 3 -1.
5.1 ANALYTIC AL RES ULTS EVALUAHO N C RITERIA
Analytical results presented in the summary tables in Sections 6 and 7 show all analytes detected
above laboratory detection limits in bold type. Analytical results indicating significant concentrations of
contaminants in source samples (Section 6) with respect to background concentrations are shown
underlined and in bold type. Similarly, analytical results indicating elevated concentrations of
contaminants in target samples (Section 7) with respect to background concentrations also are underlined
and in bold type. For the purposes of this investigation, significant/elevated concentrations are defined,
using Table 2-3 of the EPA HRS model criteria for observed releases or observed contamination
(significant or elevated concentrations) as follows.
Equal to or greater than the sample's Contract Required Quantitation Limit/Contract
Required Detection Limit (CRQL/CRDL) or the sample quantitation limit (SQL) when a
non-CLP laboratory was used; and
Equal to or greater than the background sample's CRQL/CRDL or SQL when the
background concentration is below detection limits; or
At least three times greater than the background concentration when the
background concentration equals or exceeds the detection limit.
The analytical summary tables present all detected analytes, but only those detected analytes
(specifically arsenic, cadmium, lead, mercury, and zinc) at potential sources or in targets meeting the
significant/elevated concentration criteria are discussed in the report text. All detected concentrations
are discussed for background samples, including those concentrations which were qualified as estimated
because they were detected below the SQL (JB). Because both tailings and waste rock are unique soil
10:START-2\01020028\S759
5-1
-------
waste matrices placed on surface soil, analytical results of the tailings and waste rock samples collected
were compared to the results for background surface soil. The background surface soil samples consisted
of native soil.
Two sediment samples were collected from the Kettle River (KRBK01SD and KRBK02SD).
KRBKO1SD was collected near the Box Canyon-Deep Creek Road along the Kettle River. KRBK02SD
was collected along the bank of the Kettle River just south of the U.S.-Canada border. Since these
samples were collected outside the project study area they will not be discussed in this report. However,
analytical results for these two samples are provided in Appendix E.
Analytical results are qualified as estimated (J) when the analyte is positively identified as either
present or absent based on the QC data provided by the laboratory. The associated numerical value is the
approximate concentration of the analyte in the sample. Additional qualifiers were applied when
necessary to indicate potential bias of estimated quantities including low, unknown, high, or when the
result was estimated because it was below the SQL:
B = The detected concentration is below the method reporting limit/CRDL, but is above the
instrument detection limit;
H = The numerical result is likely biased high, above the actual concentration;
L = The numerical result is likely biased low, below the actual concentration;
K = The bias of the numerical value is unknown; and
Q = The detected concentration is below the method reporting limit/CRQL, but is above the
method detection limit.
For comparison purposes, the SQL is provided in parenthesis for background results that are
qualified because they are below the SQL. When samples were diluted for reanalysis at a laboratory, the
dilution results were considered for evaluation and are provided in the tables. For target locations, only
those analytes that also were detected in a source at the mine and mill sites were evaluated to determine
whether their concentrations were elevated. All hazardous substances detected using EPA CLP results at
target locations and meeting evaluation criteria can be used to document an observed release from the
source at the mines and mills to the target.
Based on the EPA Region 10 policy, evaluation of the common earth crust elements (aluminum,
calcium, iron, magnesium, potassium, and sodium) is generally employed only in water mass tracing,
which is beyond the scope of this report. For this reason, these elements and results will not be discussed
in this report, but are presented in the analytical results summary tables when detected.
10:START-2\01020028\S759 5 -2
-------
5.2 BACKGROUND SAMPLES
Background samples were collected for each of the naturally occurring medium from which
samples were collected. Those media are surface soil and sediment. A background surface water sample
is not presented in this report since all surface water sample results discussed are from sources of
contamination which do not require comparison to background concentrations. Results for the
appropriate background sample(s) appear as the first column(s) in the analytical results summary tables
in Sections 6 and 7 for comparison against source or target results.
5.2.1 Background Surface Soil
5.2.1.1 Sample Locations
Mine and mill-specific background surface soil samples were collected for the Daisy Mine
(DTBK01SS; Figure 6-2), the LeRoi/Northport Smelter (NSBK02SS; Figure 6-17), the Anderson
Calhoun Mine/Mill (ANBK02SS; Figure 6-38), and the Van Stone Mine/Mill (US007, US008, and
US009; Appendix H).
DTBKOlSSwas located approximately 60 feet north and upgradient from Daisy Mine.
NSBK02SS was collected south of the LeRoi/Northport Smelter. ANBK02SS was located east and
upgradient of the Anderson Calhoun Mine/Mill. US007, US008, and US009 were collected upgradient
of the Van Stone Mine/Mill.
In addition, six background surface soil samples (BKOlSSand BK04SS through BK08SS) were
collected from locations within the general project area (Figure 5-1). Sample locations are listed in
Table 3-1. BKOlSSwas located south of the Comfort Inn in Colville. BK04SS was located
approximately 2.2 miles on Black Canyon Road, upgradient of mining activity. BK05SS was located
approximately 200 yards off the unnamed road leading toward residences south of Deep Creek Mine.
BK06SS was located approximately 1.5 miles upgradient from Magma Mine and near the unnamed road.
BK07SS was located along Silver Creek Road. BK08SS was located upgradient from Iroquois Mine.
The surface soil samples were collected from 0 to 6 inches bgs. The matrix of the samples
appeared similar to that of the native soil observed at the mines and mills.
For those mines and mills were site-specific background soil samples were unobtainable due to
accessibility and safety concerns, background analyte concentrations for those mine and mill sites were
established using the highest analyte concentration from all background soil samples collected. These
assignments were determined by the EPA TM. Refer to Table 5-1.
10:START-2\01020028\S759
5-3
-------
Background concentrations of TAL metals, pesticide/PCBs, TOC, and SVOCs will be compared
to source and target sample concentrations, as described in Sections 6 and 7. The purpose of the
comparison is to determine if concentrations of substances found in source and target samples are
significant/elevated with respect to background concentrations as defined, using the EPA HRS model
criteria.
5.2.1.2 Sample Results
Refer to T able 5-1 and 5-3 for E & E and WEST ON sample results, respectively.
5.2.2 Background Sediment
5.2.2.1 Sample Locations
Seven background sediment locations were sampled within the project area. Sample locations
are listed in T able 3 -1.
LBBKO1SD was located downstream of the confluence of Logan Road ditch and the unnamed
ditch adjacent to L-Bar/Northwest Magnesite and reflects background concentrations for the West Ditch
sampled at L-Bar/Northwest Magnesite. LBBK02SD was located on the Colville River near the
Burlington Railroad and U.S. 395 and reflects background concentrations for the probable point of entry
(PPE) sample to surface water at L-Bar/Northwest Magnesite (Figure 6-4).
NABK01SD was located on Stensgar Creek approximately 60 feet west of the confluence of
Stensgar Creek and the Columbia River and reflects background concentrations for Stensgar Creek and
the ditch sampled near Northwest Alloys. NABK02SD was located approximately 30 feet south of the
confluence of Stensgar Creek and the Colville River and reflects background concentrations for the
Colville River sampled near Northwest Alloys (Figure 6-6).
NPBKO1 SD was located upstream and upgradient in the unnamed creek near Napoleon
Mine/Mill and reflects background concentrations for the unnamed creek sampled at Napoleon
Mine/Mill (Figure 6-8).
NSBKO1 SD was located south of the LeRoi/Northport Smelter along the unnamed creek near
Northport-Waneta Road and reflects background concentrations for the unnamed creek sampled at the
LeRoi/Northport Smelter (Figure 6-17).
The analytical results of a sediment sample collected in May of 2001 by Ecology at Lower
Arrow Lake in Canada (sample number 01198040) will be used to establish background concentrations
for the sediment samples collected along the Columbia River (Figure 6-18).
10:START-2\01020028\S759
5-4
-------
ANBK01SD was located approximately 200 yards south of the Anderson Calhoun Mine/Mill on
the unnamed creek which flows through the site. ANBKO1SD reflects background concentrations for the
unnamed creek sampled at the Anderson Calhoun Mine/Mill (Figure 6-38).
For those mine and mill sites where site-specific background sediment samples were
unobtainable due to accessibility and safety concerns, background analyte concentrations were
established using the highest analyte concentration from all background sediment samples collected.
These assignments were determined by the EPA TM. Refer to Table 5-2.
Sediment samples were collected at the following locations by WESTON (Appendix H):
Tributary to Tom Bush Creek and Melrose Mine (US001);
Unnamed tributary to Onion Creek and Van Stone Mine/Mill (US005);
Unnamed tributary to Onion Creek and Van Stone Mine/Mill (US006);
Unnamed tributary to Onion Creek and Van Stone Mine/Mill (US010);
Tributary to Black Rock Mine/Mill, Great Western Mine, and Last Chance Mine/Mill
approximately 1 mile upgradient and across Deep Creek Mine (US011);
Deep Creek South Fork approximately 7 miles upstream for Copper King Mine and
Sierra Zinc Mine/Mill (US012); and
Unnamed tributary to Deep Creek (US013).

6.1.2 Historical Information
The Daisy Mine is a former copper, lead, gold, and silver mine (Derkey et al. 1990). The mine is
located 25 miles west of Addy near the summit on Huckleberry Mountain, Washington (Battien 1998).
The mine also is reported to have produced between 1916 and 1935 (Derkey et al. 1990). It is reported
that the presence of arsenic prompted the closure of the mine (Battien 1998). The mine claim was
located in 1887, but with almost impassable roads and lack of transportation the claim was not developed
10:START-2\01020028\S759
6-1
-------
until 1905 when J.J. Browne and W.E. Seelye of Spokane took over the property (Battien 1998).
Historical ownership from this time to the present is unknown.
6.1.3 Mine Description/Features
The Daisy mine is located on the west slope of the Huckleberry Range in the Kettle Falls mining
district. Alternate names are Daisy-Tempest and Silver Mountain. The mine consisted of 16 claims and
additional property encompassing approximately 580 acres. The mine deposit consists of at least
four quartz veins from a few inches to 12 feet in width cut by a series of argillites and quartzites intruded
by diorite. The mine is developed by four adits and a shaft. (Huntting 1956)
6.1.4 START-2 Mine Visit
On September 10, 2001, the START-2 visited the Daisy Mine and conducted a visual inspection
of the property and surrounding area (Figure 6-1; Appendix A, Photos 43-1 through 43-21; Appendix B,
Team 2 Phase 2, Pages 2 through 7). The mine area contained a tailings pile measuring 150 feet at the
base, 30 feet in height with a slope of approximately 35%, and a depth of approximately 45 feet. A
storage shed was located north of the tailings pile measuring 10 feet by 10 feet. East of the tailings pile
and dirt road were an old office building, an outhouse, and a shed. North of the tailings pile and storage
shed were the remnants of a building or shed. West of the remnants a shaft was located measuring
10 feet by 10 feet by unknown depth. A wet area originating from the shaft extended south
approximately 25 feet. A depression south of the wet area was noted where potential pooling of water
from the shaft would occur; continuing on to flow into a ditch (PPE 1), through a culvert, and into Magee
Creek located southwest of the site. The overland distance from the shaft to the creek is approximately
70 feet. Access to the mine is unrestricted. Logging occurs in the vicinity of the mine. No livestock
grazing was noted in the vicinity of the mine.
6.1.5 Sampling Locations
Sample locations are depicted in Figure 6-2. Three tailings samples (DTTP01SS, DTTP02SS,
and DTTP03SS) were collected from the tailings pile adjacent to Daisy Mine Road. The samples were
collected within the overland surface water drainage routes identified by the START -2. The samples
were collected to determine potential contamination associated with this source. The samples appeared
to consist of silty sand. No odor or staining was noted during sample collection.
10:START-2\01020028\S759

-------
One surface water sample (DTAD01SW) was collected from the shaft. The sample was
collected within the overland surface water drainage route identified by the START-2. The sample was
collected to determine potential contamination associated with this source. The sample was clear. No
odor or staining was noted during sample collection.
A sediment sample (DTPP01SD) was collected at PPE 1 in the ditch near the culvert on the
southern portion of the mine area.
6.1.6 Analytical Results
6.1.6.1 Surface Soil Sample Results
The START -2 collected three surface soil samples from tailings for TAL metals analyses.
Arsenic was detected at a significant concentration of 233 milligrams per kilogram (mg/kg). Significant
concentrations ranged from 0.42 mg/kg to 2.9 mg/kg for mercury. Refer to Table 6-1 for complete data
results.
6.1.6.2 Surface Water Sample Results
The START-2 collected one surface water sample from the shaft water for TAL metals analysis.
Analytes detected in DTAD01SW include arsenic (95.3 micrograms per liter |/ig/L|). cadmium
(7.1 /ig/L), lead (5.2 /ig/L), and zinc (829 /ig/L). Copper and mercury were not detected.
6.1.6.3 Sediment Sample Results
The START-2 collected one sediment sample from PPE 1 for TAL metals, pesticide/PCBs, and
TOC analyses. No elevated concentrations were detected. Refer to Table 6-2 for complete data results.

6.2.2 Historical Information
L-Bar/Northwest Magnesite is located approximately two miles south of Chewelah, Washington
on the west side of U.S. Highway 395, and lies on the south bank of the Colville River (CH2MHill
2001a, Ecology 2001). Northwest Magnesite is a former magnesite plant created in 1916 by American
Mineral Production Company (Battien 1998). Shipments of crude magnesite from Stevens County
averaged 700 tons daily (Battien 1998). The plant was closed down in 1968 (Battien 1998).
L-Bar/Northwest Magnesite includes an industrial area covering approximately 80 acres and an
adjoining 17-acre agricultural field located between the industrial area and the Colville River in the
Colville River valley (Ecology 2001). An above-grade magnesite residue pile, approximately 30 feet
deep and 17 acres in area, is found to the west (Ecology 2001). Two ditches, the Main Ditch and the
West Ditch, run through the site. Both ditches previously discharged into the Colville River.
L-Bar/Northwest Magnesite and the adjacent parcel to the south have been associated with
magnesium processing since the 1930s. Large quantities of magnesite ore were processed and flue dust
and other materials were stockpiled on site until 1967. In the mid-1970s, the facility was converted to
recover magnesium from a magnesium processing byproduct commonly referred to as flux bar. Flux bar
was supplied primarily by Northwest Alloys, Inc., from their magnesium plant near Addy, Washington,
and sold to the site owners. The magnesium recovery facility was owned and operated by Phoenix
Resources Recovery, Inc., from 1977 to 1986. L-Bar Products, Inc., operated the facility from 1986 to
1991 when it closed down due to insolvency (CH2MHill 2001a). More than 100,000 tons of materials
(under a covered pile, in buildings, and on top of the magnesite pile) remained at the site after closure
(Ecology 2001).
Ownership of a majority of the L-Bar property was transferred from the L-Bar Bankruptcy
Trustee to Northwest Alloys, Inc., in May 2000. The transfer included all former L-Bar Products, Inc.,
real estate except those portions lying under the south half of the magnesite residue pile, which were
retained by the L-Bar trustee, and later transferred to Richard and Maxine Brauner. The north half of the
magnesite pile and the underlying property is owned by William Brauner. Easements are in place in the
10:START-2\01020028\S759 6 -4
-------
existing deeds that grant Northwest Alloys, Inc., and its agents access to the magnesite pile for purposes
of groundwater monitoring and future remedial actions, if needed. (CH2MHill 2001a)
Since 1995, discharge from the Main Ditch has stopped as a result of actions taken by Northwest
Alloys, Inc. In response to an Emergency Enforcement Order issued by Ecology in 1994, Northwest
Alloys, Inc., constructed a water retention structure that eliminated direct discharge of Main Ditch
surface water to the Colville River. (Ecology 2001)
In 1995, Ecology and Northwest Alloys, Inc., entered into an Agreed Order to conduct interim
actions, a remedial investigation (RI), and a feasibility study. Interim actions conducted included:
management of stored waters in the evaporation pond (through land application in the North Field during
the summer months) and the removal and disposal of approximately 65,000 tons of flux bar and flux bar
residue from atop and around the magnesite residue pile. (Ecology 2001)
Findings in the RI completed in 1998 show that flux bar and flux bar residue materials are the
primary source of ammonia, chloride, and total dissolved solids detected in the shallow groundwater,
soils, and in surface water in two on-site ditches. The shallow groundwater is not a drinking water
aquifer; however, it discharges to the Colville River which has been categorized by Ecology as a Class A
(excellent) surface water body. The West Ditch also discharges to the Colville River. River sampling
showed a slight increase in ammonia and chloride concentrations when comparing upstream to
downstream results. However, Class A surface water criteria have not been exceeded in the river.
(Ecology 2001)
Ecology prepared a draft Cleanup Action Plan that became final in June 2000. The cleanup
actions selected by Ecology are source removal, monitoring, and institutional controls. With source
removal, contaminants in groundwater, surface water, and soils are expected to be reduced over time
through natural attenuation. (Ecology 2001)
6.2.3 Plant Description/Features
The magnesite pile is believed to consist predominantly of magnesium carbonate derived from
Finch, Red Marble, and Keystone quarries several miles west of the site. Processed (washed and
crushed) magnesite ore was delivered to the Northwest Magnesite reduction facility via a 5-mile-long
aerial tramway. Electrostatic precipitate (ESP) dust from the site and perhaps other materials were
hydraulically placed into portions of the existing magnesite stockpile. A Washington State Department
of T ransportation aerial photo of the site in July 1966 shows the placement of the ESP dust by flume
discharge from the plant into a dike retaining pond system in the pile area. (CH2MHill 1998)
10:START-2\01020028\S759
6-5
-------
In addition to magnesite processing, a fireproof fiber-board product called Thermax was
manufactured at the site before L-Bar operations commenced. The Thermax fiber boards consisted of
shredded Cottonwood impregnated with magnesite. Little is known about the operation; however, many
of the older L-Bar buildings are constructed of Thermax. Thermax debris is found as a waste material
mixed into the magnesite stockpile. (CH2MHill 1998)
Past operating practices and inadequate storage of flux bar and flux bar residue have resulted in
elevated levels of mostly chloride and ammonia in shallow groundwater and surface water. Most of the
materials remaining on the plant have continued to leach salts and ammonia into shallow groundwater
and surface water in two ditches. (Ecology 2001)
To date, 140,000 to 150,000 tons of flux bar related material has been removed from the
property. There is an estimated 30,000 to 40,000 tons of material still is present on site. Removal of this
material and backfilling are tasked to be complete by 2002. These activities are being conducted under
an Agreed Order with Ecology (Wilkinson 2002).
Results from the Draft Interim Action Materials Characterization Report (1996) produced by
Cascade Earth Sciences (CES) for Northwest Alloys Inc. showed the magnesite residue pile contained
elevated levels of some trace metal and semi-metallic constituents including arsenic, boron, cadmium,
copper, selenium, and zinc. Concentrations of these constituents in the magnesite residue pile were
elevated in comparison to both regional background soil levels for eastern Washington and to levels
measured in L-Bar flux bar residue. (CH2MHill 1998)
Sediment samples were collected during Phase I of the RI from six locations: three in the Main
Ditch, two in the West Ditch, and one from the Logan Road ditch south of the property. Review of trace
metals analytical results demonstrated that barium, manganese, and selenium concentrations in the Main
Ditch sediment samples exceeded the concentrations detected in the background sample collected from
the Logan Road ditch south of the property. Trace metals results from the West Ditch samples were
similar to Main Ditch samples in that background concentrations were exceeded for barium, manganese,
and selenium. Background concentrations of arsenic and copper also were exceeded. Concentrations of
these metals were less than 2 times background levels except for selenium, which was approximately
seven times background. (CH2MHill 1998)
6.2.4 START-2 Visit
On September 10 and 11, 2001, the ST ART-2 visited L-Bar/Northwest Magnesite and conducted
a visual inspection of the property and surrounding area (Figure 6-3; Appendix A, Photos 40-1 through
10:START-2\01020028\S759
6-6
-------
40-22 and 41-8 through 41-11; Appendix B, Team 1 Phase 2, Pages 3 through 7, 9 and 10). The property
consisted of six buildings including primary crushing and storage, maintenance and repair shop,
magnesium recovery and storage (the cooling beds area was demolished in 1994), secondary crushing
and butler storage, office and laboratory, and storage bunkers. Six exterior product storage silos are
south of the storage bunkers. The buildings contain process equipment and flux bar residue products in
various stages of development and storage. The complete list of materials and the building plans
showing material locations can be found in the Draft Interim Action Materials Characterization Report
produced by CESin 1996. (CH2MHill 1998)
Other significant features include three lined ponds (the evaporation, holding, and sanitary
lagoon) and the covered flux bar residue pile north of the buildings. The area around the buildings is
paved with asphalt to control dust and divert surface water runoff to collection ditches for discharge to
the holding pond. If the holding pond becomes full, it is equipped with an overflow that allows discharge
to the Main Ditch. Storm water contained in the holding pond is being discharged to the Colville River
under an Ecology-approved storm water management permit (PPE 2). Underground and overhead utility
lines are distributed throughout the site. No registered underground storage tanks are present on the
property. (CH2MHill 1998)
No logging occurs in the vicinity of the plant. Farmland is located adjacent to the property.
6.2.5 Sampling Locations
Sample locations are depicted in Figure 6-4. Two sediment samples were collected in the West
Ditch. Sediment sample LBDT03SD was collected from PPE 1 and sediment sample LBDT02SD was
collected from PPE 2.
6.2.6 Analytical Results
6.2.6.1 Sediment Sample Results
The START-2 collected one sediment sample from PPE 1 (LBDT03SD) and one sediment
sample from PPE 2 (LBDT02SD) for TAL metals, pesticide/PCBs, and TOC analyses. No analytes were
detected at elevated concentrations in these samples. Refer to Table 6-3 for data results.

6.3.2 Historical Information
Northwest Alloys is a former magnesium plant in Addy, Washington, covering approximately
240 acres (Northwest Alloys, Inc. 1992). The plant is located in Colville Valley which is drained by the
Colville River. The Colville Valley is bordered by rugged, mountainous terrain. Access to the plant is
restricted. In the early 1970s, Northwest Alloys, Inc., a wholly owned subsidiary of the Aluminum
Company of America decided to develop a plant for the production of ferrosilicon, magnesium, and
silicon in Addy, Washington (DNR 1983). Construction began in 1973 and production began in 1976
(DNR 1983). Plant operations were discontinued in September 2001 due to economic considerations
affecting domestic magnesium production.
6.3.3 Plant Description/Features
The plant produced magnesium and ferrosilicon partially from raw material quarried on the
property. Waste products generated were either recycled, sold as product or thread, or buried on site.
None of the wastes were regarded as hazardous under the Resource Conservation and Recovery Act
(RCRA) but were classified as regulated wastes under Ecology Dangerous Waste Regulations.
(E & E 1988)
The magnesium was sold to the aluminum industry as an alloying ingredient and to the steel
industry as a desulphurization agent. Ferrosilicon was used internally as a reducing agent in magnesium
production. Northwest Alloys, Inc., employed the Magnetherm (Aluminathermic) process which
depended upon the reaction between calcined dolomite (a mixture of calcium dioxide and magnesium
10:START-2\01020028\S759
6-8
-------
oxide) and the silicon content of ferrosilicon. The reaction took place in a liquid slag formed from the
reaction of the calcium and silicon byproducts. Alumina was needed in the process to reduce the melting
point of the slag and to depress unwanted secondary reactions. Aluminum was used for the same purpose
and was also a supplemental reductant. (E & E 1988)
The major raw material, dolomitic limestone, was quarried from a deposit adjacent to the plant.
A second raw material, pure aluminum shot, aluminum skim, or alumina, was brought in by rail.
Ferrosilicon, the third material used, was produced on site from locally mined quartzite or was brought
in. (E & E 1988)
Quarried dolomite was crushed, washed, screened, and stockpiled. Because water and carbon
dioxide in the dolomite will reduce magnesium production efficiency, it was necessary to calcine the
dolomite to reduce the water and carbon dioxide to a minimum. The calcining operation was carried out
in a rotary kiln in which the dolomite traveled counter-current to hot combustion gases in the kiln.
(E & E 1988)
The calcined dolomite, plus ferrosilicon and aluminum or alumina, was fed from bins to the
batch-operated magnesium reduction furnaces. The furnaces were operated under vacuum and were
totally enclosed. The magnesium, produced as a vapor, rose from the furnace into a condenser and was
collected and solidified in crucibles. (E & E 1988)
The used condenser-crucible assembly was taken to a cleaning area and disassembled. The
condenser and connecting pipes were cleaned and prepared for reuse. The crucible was removed and
transported to the metal service area where the magnesium was remelted, refined, cast into ingots, and
shipped out by rail or truck. (E & E 1988)
In 1979, Northwest Alloys, Inc., began to fill the excavated south quarry with waste products of
which 10% were regulated wastes. The regulated wastes were sandwiched between layers of
low-permeability slag in the landfill. The south landfill/quarry was estimated to be filled to capacity by
1990, at which time the west quarry would be utilized for waste disposal. Prior to 1980, Northwest
Alloys, Inc., disposed of their regulated wastes on the ground at the south portion of the facility.
(E & E 1988)
The plant was designed as a zero-discharge facility. All cooling water was recirculated and
perimeter dikes contained and treated all surface water runoff (E & E 1988).
During the late 1970s, and into the 1980s, various non-hazardous production byproducts from the
plant operations were placed into three shallow, soil-lined repositories in a portion of the site referred to
as the Northwest (NW) Quadrant area. The three repositories include the Sealed Pit, Casting Residue
10:START-2\01020028\S759
6-9
-------
Mound (CRM), and North Waste Area. Some of the solid waste materials that were placed into the
repositories were chloride and ammonia bearing, and/or displayed an elevated pH. Since 1995,
Northwest Alloys, Inc., has conducted a series of characterization and monitoring activities within and
around these repositories under the Model Toxics Cleanup Authority, Voluntary Cleanup Program, as
administered by Ecology's Industrial Section. A focused hydrogeologic investigation in 1995 identified
chloride and ammonia in shallow groundwater immediately adjacent to the waste repositories in the NW
Quadrant area and adjacent to the wastewater storage ponds at the southern end of the plant. In 1999,
Northwest Alloys, Inc., began the excavation and removal of approximately 25,000 tons of waste
material as part of its ongoing voluntary cleanup actions. The wastes were shipped off-site to a
non-hazardous subtitle D landfill in Roosevelt, Washington. In 2000, Northwest Alloys, Inc., installed a
RCRA-compliant liner system as an engineering upgrade for a previously unlined stormwater storage
pond. The contents of the two wastewater storage ponds have been transferred to the lined pond. The
two wastewater ponds are now empty and available for storage of stormwater. Also in 2000, removal
actions at the Sealed Pit were completed with soil removal conducted along Marble Valley Road.
(Northwest Alloys, Inc. 2001)
In 2001, excavation and removal of material from the CRM was conducted and characterization
sampling of the North Waste Area was performed (Northwest Alloys, Inc. 2001).
Removal of waste materials from the North Waste Area is ongoing. Other activities planned for
2002 include additional soil removal at the CRM and backfilling of the CRM and Sealed Pit areas.
Closure of the RCRA Part B Landfill located on the property is also underway. (Wilkinson 2002)
T errain is flat in the southern half of the site and hilly in the northern half. Mining and filling
operations have changed the topography of the site over its operational history. Artificial fill covers
much of the NW Quadrant. Native grade is observed along the western margins of the plant, along
Marble Valley Road. Presently, ground elevations in the NW Quadrant of the plant site range from about
1650 to 1665 feet above mean sea level (msl). (CH2MHill 2001b)
Groundwater contamination by inorganic compounds has been documented below an on-site
quarry used for disposal of wastes. The contamination appears limited in extent and no present-day
migration of contaminants to drinking water aquifers appears likely. (E & E 1988) Analytical results of
routine monitoring conducted at the City of Addy municipal water supply wells is provided in
Appendix I.
Two surface water features, the Colville River and Stensgar Creek, are present within the
immediate vicinity of the Northwest Alloys' Addy plant. The Colville River is located about 500 feet
10:START-2\01020028\S759
6-10
-------
east of the plant site and Stensgar Creek is located about 1,000 feet south of the plant. Surface water
runoff from the NW Quadrant area generally is to the west and south. (CH2MHill 2001b)
6.3.4 START-2 Visit
On September 10,2001, the ST ART-2 visited Northwest Alloys and conducted a visual
inspection of the property and surrounding area (Figure 6-5; Appendix A, Photos 40-23 through 41-7;
Appendix B, Team 1 Phase 2, Pages 7 through 9). The current facility layout and surrounding areas are
shown in Figure 6-5. The plant is contained within gates and hillsides. There is no overland flow from
the site directly into the Colville River due to topography and surface water runoff controls. A potential
overland flow exists via a series of road side ditches on the southern portion of the plant. The overland
flow potentially flows through these ditches to a ditch leading from the road on the south end of the
property south towards Stensgar Creek (PPE 1). Stensgar Creek, located south of the plant, contains
brown trout. Stensgar Creek Feeds into the Colville River. The terrain is flat in the southern portion of
the property and hilly in the northern portion.
6.3.5 Sampling Locations
Sample locations are depicted in Figure 6-6. NADT01SD was collected in the ditch
approximately 25 feet north of the confluence of the ditch and Stensgar Creek (PPE 1).
6.3.6 Analytical Results
6.3.6.1 Sediment Sample Results
The START-2 collected one sediment sample from PPE 1 (NAD01SD) for TAL metals analyses.
Elevated concentrations of arsenic (4.9 mg/kg), copper (18.7 mg/kg), lead (7.5 mg/kg), and zinc
(47.9 mg/kg) were detected in this sample. Refer to Table 6-4 for complete data results.

1913-1917, and 1938-1955 (Derkey et al. 1990). A mill was built in 1910 to extract gold (Battien 1998).
The mine/mill was owned in 1915 by British Columbia Copper Company (Battien 1998). Historical
ownership information from the time the facility began operation to the present is unknown.
6.4.3 Mine/Mill Description/Features
The Napoleon Mine/Mill consists of two claims. The exposed formation is part of the Mission
argillite. The ore minerals are magnetite, limonite, pyrite, and pyrrhotite. Occasional small quantities of
chalcopyrite are present. The ores were mined to a considerable extent and shipped to the smelter at
Greenwood, British Columbia, where it was used as a flux. The property is developed by three main
tunnels and a large glory hole. The highest workings in the glory hole are at an elevation of 2,650 feet.
These workings are all connected with stopes and raises. A one-mile aerial tramway was built from the
mine to the bunkers at the railroad along Kettle River. (Weaver 1920)
6.4.4 START-2 Mine/Mill Visit
On September 12, 2001, the START-2 visited the Napoleon Mine/Mill and conducted a visual
inspection of the property and surrounding area (Figure 6-7; Appendix A, Photos 41-12 through 41-17;
Appendix B, Team 1 Phase 2, Pages 11 and 12). The mine/mill area consisted of an adit measuring 5 feet
by 4 feet located south of the dirt road entrance. There was no evidence of tailings or waste rock present
on the property. The adit discharge flowed across the dirt road, down the hillside approximately
120 feet, before entering an intermittent creek (PPE 1). Iron staining was present on the soil and the dirt
road. There was no adit discharge at the time of the visit. Access to the mine/mill was restricted by a
locked gate. No logging or livestock grazing was noted in the vicinity of the property.

6.12.2 Historical Information
The Van Stone Mine/Mill is a former cadmium, lead, and zinc mine/mill located on the upper
portion of Onion Creek near Northport, Washington (Derkey et al. 1990). The mine is reported to have
produced in 1930, 1937, 1942, and 1952-1956 (Derkey et al. 1990). Production to the end of 1956 was
2,242,960 tons of ore milled, yielding 10,700 tons of lead concentrates and 120,000 tons of zinc
concentrates (Mills 1977).
George Van Stone claimed and worked the mine/mill until 1926 (Battien 1998). Hecla Mining
Company acquired the property in 1926, and Van Stone Mining Company took over in 1930
(Battien 1998). Willow Creek Mines of Nevada operated the mine/mill from 1938 to 1942 (Mills 1977).
In 1950, American Smelting and Refining of Salt Lake City bought the claims and the surrounding land
(Battien 1998). The property was operated intermittently by Asarco, Inc., during the 1950s and 1960s
(Beacon 1999). In 1972, Callahan Mining Corporation acquired the mill and mine property
(Mills 1977). Equinox Resources, Inc., acquired the property in 1990 and placed it back into production
in 1991 (Beacon 1999). The operations were suspended in late 1992 due to low metal prices and have
been under care and maintenance since January 1993 (Beacon 1999). Equinox Resources, Inc., filed a
preliminary Reclamation and Closure Plan with the Washington State Department of Natural Resources
(DNR) prior to the reopening of the mine/mill in 1991. Under current legislation, Equinox Resources
Inc., is required to file a revised Reclamation and Closure Plan (Beacon 1999). The Reclamation and
Closure Plan present two possible outcomes; closure of existing operations without additional mining,
10:START-2\01020028\S759 6-20
-------
and closure following the mining and processing of additional known ore reserves (Beacon 1999). The
objective of the Reclamation and Closure Plan is to provide a systematic approach to decommissioning
the Van Stone Mine/Mill and returning all disturbed lands associated with the mine/mill operations
(post-1971) to a mixed land use capability. The mixed land use classification is defined as consisting of
a combination of forest lands, open space lands, shrub and grasslands, wetlands, wildlife habitat, talus
slopes, and agricultural lands (Beacon 1999).
6.12.3 Mine/Mill Description/Features
The Van Stone Mine/Mill is on the east side of the Columbia River and southwest of Northport,
Washington. Geologic setting includes deposition of heavy minerals in river gravels. Production was
from two open pits a few hundred feet south of the south margin of the Spirit pluton. The ore deposit is
within the middle dolomite unit of the Metaline Limestone, approximately 200 feet from the overlying
upper limestone unit at its closest point. (Mills 1977)
Rock was removed from the mine, crushed on site, and the usable material trucked off site for
further processing. Fine-grained tailings were carried in a slurry via an elevated wooden flume first to
the old tailings pile, and later to a large tailings pile located in Sections 29 and 30. The slurry was
dumped into the pile to allow the sediment to settle out of the slurry. The new tailings pile walls were
built up from dried tailings and at present stand 10 to 50 feet above the ground surface. The wooden
slurry line was replaced in the 1990s with a durable, flexible pipe. (Boise Cascade Corporation 1997)
The Van Stone Mine/Mill operations were located in the Onion Creek watershed approximately
21 miles northeast of Colville, Washington. Onion Creek has been categorized by Ecology as a Class
AA (extraordinary) surface water body. A comprehensive analyses of the entire Onion Creek watershed
titled Onion Creek Watershed Analysis was carried out in March 1997 for Boise Cascade Corporation by
a number of organizations, including DNR, Ecology, Stevens County Conservation District, Vaagen
Brothers Lumber, Arden Tree Farm, Inland Empire Paper, Maurice Williamson, and the Washington
Farm Forestry. The purpose of the assessment was twofold: to provide an understanding of the current
and possible future states of channel conditions, and to locate accessible fish habitat in the watershed to
identify existing conditions and habitats of special concern. The assessment identified localized
evidence of land use impacts to fish-bearing channels including a disturbance described as "major" in the
tributary adjacent to the Van Stone Mine due to an apparent tailings pipe-burst or associated slope failure
which occurred prior to 1968. (Raines, et. al. 1997)

6.12.4 START-2 Mine/Mill Visit
On June 22 and 23, 2001 the START-2 visited Van Stone Mine/Mill and conducted a visual
inspection of the property and surrounding area (Figures 6-9 through 6-11; Appendix A, Photos 1-1
through 9-25; Appendix B, Team 1 Phase 1, Pages 24 and 25; Team 2 Phase 1, Pages 10 through 12;
Team 3 Phase 1, Pages 20 through 22). The mine/mill area consisted of a waste rock storage area, two
tailings piles, an open pit, a seepage pond, buildings, and stained soil areas.
The waste rock storage area was constructed by end dumping to the south contour from the open
pit haul road. The eastern toe of the waste rock storage area consists mostly of larges and is located less
than 100 feet of the Northeast Fork of Onion Creek. Slopes on the north side of the haul road consist, in
part, of colluvial overburden. Depth and quantity of overburden has yet to be determined.
(Beacon 1999)
The tailings embankments consist of steep sided erodable tailings sands. In some locations the
slopes are heavily rilled, particulary along the south and west faces. (Beacon 1999)
A rock-lined spillway and discharge channel has been installed in the extreme northeast corner of
the main tailings impoundment to direct any excess accumulated rainwater to the adjacent drainage.
Tailings area water quality is monitored every 90 days and is reported to be suitable for discharge under
the facility's Washington State Water Discharge Permit or can be used for irrigation purposes.
A seepage pond is located adjacent to the tailings facility.
The open pit, located in the most southern portion of the area, is oblong in shape with an average
width of 120 feet, an average length of 317 feet, and a maximum depth of 460 feet. The pit is flooded to
an elevation of 3,510 feet or 170 feet above the current pit bottom. The rim of the open pit and portions
of the top bench currently support vegetation. The water in the open pit is separated from a tributary to
the Northeast Fork of Onion Creek by a narrow rock-filled berm. The water level in the open pit is static
at 3,510 feet elevation and excess water seeps through the berm to the adjacent creek (PPE 3).
(Beacon 1999)
The buildings on site include the process plant, crushing plant, mill building, mill shop,
warehouse, change house, assay office, garage, scale house, core storage, switch building, pit shop,
conveyor system, reagent and fuel storage areas, bunk house, and four residences. Other miscellaneous
items include a 20 million gallon water tank, return water tank, power feeders, pump power line, T-6
tractor, car spotter, tailings pipe line, tailings flume, tailings dam, 60 million gallon water tank,
200 million gallon water tank, fire mains and hydrants, domestic water main, two pipe lines, three dams
10:START-2\01020028\S759

and pipe lines, pit power lines and switchgear, pit water line, pit air line, mine shop equipment, and road
equipment. (Beacon 1999)
Six areas of stained soil were noted on the property. The first area was near a liquid propane
tank south of the mill building. The second area was near elevated transformers adjacent to the mill
building. At this location the soil was stained orange and green. The third area was near an aboveground
storage tank (AST) with secondary containment near the entrance to the mine/mill. The containment area
was filled with water and smelled of diesel. No sheen was noted. The secondary containment had been
breached. The fourth area was on a concrete pad with staged transformers and stained soil south of the
liquid propane tank. The fifth area was near staged 55-gallon drums surrounded by stained soil west of
the mine/mill buildings and south of the Roundup Powder Company abandoned building. The sixth area
was near another AST area surrounded by stained soil located east of the shed and staged 55-gallon
drums.
Several unnamed creeks were located adjacent to the property. One unnamed creek was located
south of the mine pit water and could not be accessed due to safety concerns. A second unnamed creek
was located at the southwest portion of the old tailings pile. Surface water runoff from this pile drains to
this creek (PPE 4). A third unnamed creek was located on Boise Cascade Corp. property; no sample was
collected due to lack of access. A fourth unnamed creek was located adjacent to the tailings pile near the
entrance to the mine/mill. Surface water runoff from the tailings pile also drains to this creek at two
locations (PPE 1 and PPE 2). Excess water from the on-site open pit seeps through the pit berm to an
adjacent creek (PPE 3).
A number of public, private, and commercial interests access the mine/mill access road. Boise
Cascade Forest District maintains an easement over the road to access their timber holdings. Washington
Water Power maintains an easement over the road to access a substation located on the mine/mill
property. There are residences near the road junction and the DNRuses the road for fire control.
(Beacon 1999)
Access to the mine/mill is restricted by two locked gates. No logging or grazing was noted in the
vicinity of the property.
6.12.5 Sampling Locations
Sample locations are depicted in Figures 6-12 through 6-14. Twelve waste rock samples
(VSWP01SS through VSWP12SS) were collected from the waste rock pile. The samples were collected
within the overland surface water drainage routes identified by the START-2. The samples were

collected to determine potential contamination associated with this source. The samples appeared to
consist of tan/gray, fine sand with gravel and rocks. No odor or staining was noted during sample
collection.
Twenty-one tailings samples (VSTP01SS through VST P21SS) were collected from two tailings
piles. The samples were collected within the overland surface water drainage routes identified by the
START-2. The samples were collected to determine potential contamination associated with this source.
The samples appeared to consist of dark gray/brown, fine, dry sand and tailings. No odor or staining was
noted during sample collection. Samples VSTP01SS through VSTP09SS and VSTP21SS were collected
from the tailings pile located near the entrance to the mine/mill. Samples VSTP1 OSS through
VSTP20SS were collected from the old tailings pile located on the eastern portion of the mine/mill.
Seven surface soil samples (VSSSO1 SS through VSSS07SS) were collected from stained soil
areas around the mine/mill property. The samples were collected from stained areas identified by the
START-2. The samples were collected to determine potential contamination associated with these
sources. Odor and staining was noted during sample collection.
One co-located surface water and sediment sample (VSMW01SW and VSMW01SD) was
collected from the mine pit water. The sample was collected within the overland surface water drainage
route identified by the ST ART -2. The sample was collected to determine potential contamination
associated with this source. The surface water sample was clear and blue-green in color. No odor or
staining was noted during the surface water sample collection. The sediment sample appeared to consist
of silty sand to fine gravel, gray to light brown in color, with a slight odor. No staining was noted during
sediment sample collection.
One sediment sample (VSPP01SD) was collected at PPE 1 from the confluence of the tailings
pile and the pond located near the entrance of the mine/mill.
One sediment sample (VSPP02SD) was collected at PPE 2 from the potential overland flow from
the tailings pile to the unnamed creek located near the entrance of the mine/mill.
One sediment sample (VSPP03SD) was collected at PPE 3 from the northwest corner of the mine
pit water area.
One sediment sample (VSPP04SD) was collected from PPE 4 near the southwest portion of the
old tailings pile at the confluence with an unnamed creek.

6.13.2 Historical Information and Mine Description/Features
The Hope and Twin Cabins Mine is a former copper, gold, and silver mine located in the Fifteen
Mile Creek district, Washington. An estimated 100 tons of ore were produced. The ore deposit consists
of pyrrhotite containing some chalcopyrite in a mineralized zone about seven feet wide and lying in the
acidic dioritic dike rock. The claim is developed by two tunnels, each about 30 feet in length. In
addition, there are several open cuts and shallow shafts (Weaver 1920). Historic ownership information
from the time of patent to the present is unknown.
6.13.3 START-2 Mine Visit
On June 24, 2001, the START -2 visited the Hope and Twin Cabins Mine and conducted a visual
inspection of the property and surrounding area (Appendix B, Team 2 Phase 1, Page 13). The area
consisted of a shaft and a waste rock pile. The shaft measured approximately 15 feet by 15 feet by
30 feet to water. The waste rock pile measured an estimated 20 feet by 35 feet by 4 feet deep
(Appendix A, Photos 29-21 and 29-22). The START-2 did not observe any overland drainage routes
from the waste rock pile to surface water. Access to the mine was unrestricted. No residents or potential
receptors were observed on the property. No samples were collected at the Hope and Twin Cabins Mine.

6.14.2 Historical Information and Mine Description/Features
The St. Crispin Mine is a former copper, gold, lead, and silver mine situated on Sheep Creek,
approximately one mile west of Northport, Washington. The formation exposed in the bed of Sheep
Creek is a dark, carbonaceous argillite. A shaft was sunk in the creek to a depth of 16 feet on a
mineralized zone in the argillite. Eight other similar mineralized zones are reported to occur to the
southwest. Back from the creek a second shallow shaft was sunk and from it several drifts were driven
(Weaver 1920). Historical ownership information from the time of patent to the present is unknown.
6.14.3 START-2 Mine Visit
On September 13, 2001, the START-2 attempted to locate the St. Crispin Mine. The START-2
followed an access road along Sheep Creek to a campground area at the end of the road. The START-2
continued on foot for approximately a quarter mile along Sheep Creek. No shafts were identified;
however, they could have been submersed under water. The ST ART-2 returned to the campground area
to collect latitudinal and longitudinal coordinates. No samples were collected at the St. Crispin Mine
because the mine was not located.

6.15.2 Historical Information and Mill Description/Features
The Northport Mill is a former rock ore mill situated adjacent to Washington State Highway 25,
in Northport, Washington. The property was listed under Kendrick Mercantile Company (1925), Mines
Management, Inc. (1951), Idaho Continental Mines, Inc. (1964), Silver Crown Mining Company, Inc.
(1970), Tri H Mining Company, Inc. (1979), Crown-S, Inc. (1981), Northport Mill (1985), Matovich
Mining Industries, Ltd. (1990), and Mountain Minerals Northwest Company, Ltd. (1992). Mountain
Minerals Northwest Company, Ltd., is a division of Highwood Resources Ltd., the current property
owner. The property occupies approximately 16 acres. (Pepper 2001)
Highwood Resources, Ltd., operated a rock ore mill at the site from the late 1980s to early 1990s.
The plant feed was impure barite rock mined in the vicinity. The ore was processed for barium sulfate.
The rock ore was crushed then ground, with barite separated using floatation processes. Various
chemicals and reagents were added to cause the barite to float and the calcium carbonate and silica to
settle during floatation. The material that did not float was pumped to a tailings pond by overhead
piping. The tailings pond is lined with a high-density polyethelene (HDPE) 80 millimeters
(Pepper 2001). The lined tailings pond has a waste water re-circulation system of approximately
10,000 cubic feet of volume (Ecology 1990). The dried product was pneumatically conveyed (blown by
dry air) through an underground pipeline to the product storage silo (Pepper 2001).
In August 2002, Highwood Resources, Ltd., the current property owner, conducted the disposal
of laboratory chemicals and drummed waste/tailings present on the property. Disposal activities were
conducted by Spencer Environmental, Portland, Oregon. An inventory of chemicals and wastes/tailings
that were removed from the site was provided to the EPA. As of September 2002, twenty drums of mill
reagents remain on site. All twenty drums have been overpacked. The property owner is exploring
opportunities for use of the reagents elsewhere and continues to address the environmental issues with
this site under the direction of Ecology. (Dumaine 2002).

6.15.3 EPA Visit
On November 28, 2001, EPA personnel visited the Northport Mill site and conducted a visual
inspection of the property and surrounding area (Figure 6-15; Appendix B, EPA Logbook, Pages 1
through 5). The property is fenced and access is restricted by a locked gate. Representatives of
Highwood Resources Ltd. (Dan Dumaine and Terri Pepper) and representatives of the Colville
Confederated Tribes (Patti Stone and Don Hurst) were present during the visit. The area consisted of
two ASTs, a product storage silo, a conveyor plant, a tailings pond, an ore rock pile, a process building
with chemical feeders and floatation cells, a mill building with an adjoining thickener room, a dryer, an
assay laboratory, an office and a "portable-type" building used for sample preparation (Appendix A,
Photos 47-1 through 47-21). The capacity of each of the ASTs was estimated at 8,000 to 10,000 gallons
(Appendix A, Photo 47-4). The property representatives were not knowledgeable of what the tanks were
used for and believed they were empty. Three barrels observed on the property contained soil-like
material (Appendix A, Photo 47-6). According to Dan Dumaine, he sampled the barrels in the summer of
2001. At the time of the visit, he had not received the sample results. A tailings pond was also observed
on the property. Access to the tailings pond is restricted by a fence (Appendix A, Photo 47-11).
According to Terri Pepper, the pond is lined with an HDPE liner. The volume of solid material observed
at the bottom of the tailings pond was estimated to be 150 feet by 80 feet by 2 feet deep. Mr. Dumaine
mentioned that he also collected samples from the tailings pond in the summer of 2001. At the time of
the visit, he had not received the sample results. Inside the building that housed the thickener room,
numerous drums and containers were observed. Some labels indicated contents including fatty acids,
promoters, frothers, caustic soda, potassium chloride, ammonia acetate, and floatation agents
(Appendix A, Photo 47-16). Inside the assay laboratory, numerous sample jars and containers were
observed with labels indicating oxidizers, hydrochloric acid, amberine, reagents, and others
(Appendix A, Photos 47-19 and 47-20). Sheep Creek is located approximately 150 feet from the mill.
No overland drainage routes from the tailings pond to Sheep Creek were observed. No residents or
potential receptors were observed on the property. No samples were collected at the Northport Mill.
During the visit, Mr. Pepper and Mr. Dumaine briefly discussed plans by the property owner to
reclaim the site. Some of the planned activities include the proper abandonment of the tailings pond,
dismantling and removing some of the equipment found throughout the property, and the proper
removal/disposition of chemical substances on the property.

6.16.2 Historical Information
The LeRoi/Northport Smelter is a former smelter located northeast of the town center of
Northport, Washington, along Highway 25. The city of Northport is located along the east bank of the
Columbia River approximately 7 miles south of the U.S.-Canada border in Stevens County. (URS 1993)
The Northport-Waneta Road borders the LeRoi/Northport Smelter site along the south and east.
Highway 25 defines the western boundary of the site. The Burlington Northern Sante Fe Railway
(formerly the Spokane Falls and Northern Railroad) runs parallel to the Columbia River and designates
the northern site boundary. The Columbia River is located approximately 200 feet north of the
LeRoi/Northport Smelter property. Properties west of the site are residential homes. Smelter Hill is
located directly east of the site and Silver Crown Mountain is south of the site. A city park with an area
of approximately 10 acres is located northwest of the site along the Columbia River, approximately
50 feet from the site. (URS 1993)
The property encompasses approximately 32 acres and is accessed from the Northport-Waneta
Road via Highway 25 (SAIC 1997). The ground surface generally slopes toward the Columbia River in
elevation from about 1,360 feet above msl at the site to 1,290 feet above msl, the normal pool elevation
for the Columbia River (SAIC 1997). The former smelter buildings, which are no longer standing,
included the furnace building, the roaster building, and the crusher and ore building (Heritage 1981).
Beginning in 1897, the smelter refined copper, lead, and silver ores from mines in northeast
Washington, as well as copper ore from British Columbia, Canada (DHHS 1999). In 1901, the LeRoi
Company smelting operations reorganized as the Northport Smelting and Refining Company
10:START-2\01020028\S759
6-30
-------
(URS 1993). By 1908, it was one of the largest smelters on the West Coast, processing 500 tons of ore
per day (URS 1993). In 1909, the smelter closed because of competition from another smelter located in
Trail, British Columbia (URS 1993). During World War I, the government demand for lead encouraged
the Northport Mining and Smelting Company to reopen and process the lead ores that had been
discovered at Leadpoint, Washington, approximately 9 miles east of Northport (URS 1993). In
September 1914, Jerome Day purchased the smelter and renovated it to accommodate lead ores
(URS 1993). The government curtailed its lead purchases in 1921, and subsequently, the smelter closed
and was dismantled in 1922, after 24 years of sporadic operation (DHHS 1999). After the smelter
closed, the American Smelting and Refining Company purchased the site. The company removed the
smelting equipment and transported it to a smelter elsewhere (URS 1993). Between 1922 and 1953, the
inactive site was purchased by J.D. Harms. Between 1953 and 1969, a lumber mill went into operation
on the property (URS 1993). In 1975, Cecil Frazier purchased the property and operated the lumber mill
(URS 1993). In 1985, Steve Frazier purchased the property and business and operated the mill under the
name SSF Building Materials until the property was sold to the current owner in 2001.
6.16.3 Smelter Description/Features
Refer to Appendix F for historical site maps. The smelter, Breen Copper Smelter, operated from
1896 until 1901. The initial smelter operations were rudimentary and involved releases of large
quantities of pollutants. The tellurium ore was more difficult to process; however, it contained high
enough amounts of copper and gold to make the process worthwhile. Tellurium is naturally occurring
and belongs to the same family of elements as selenium and sulfur. Because of the tellurium, the ore had
to be burned or heated to release the minerals. The burning released high amounts of sulfur dioxide into
the air. (URS 1993)
The ore was processed by heap roasting, which involves open burning of the raw ore prior to
placing it in a mineral filtration furnace. The heap roasting process produced a disagreeable sulfur odor;
the local citizens termed the burning piles "stink piles." Local farmers believed that the heap roasting
process was poisoning the nearby soils. (URS 1993)
A slag brick platform was used for the initial burning, or heap roasting, of the ore. The ore was
piled on the brick platform to an approximate depth of 4 feet. Cord wood was then stacked on top of the
ore pile and ignited. The tellurium in the ore would be vaporized during this process, thus freeing the
gold and copper for smelting. The location of this brick platform is where the Northport city wells are
10:START-2\01020028\S759
6-31
-------
currently located. Refer to Appendix G for Northport city wells analytical results collected by Stevens
County. (URS 1993)
The burned ore was then placed into the furnace where the separation of the minerals took place.
Limerock was used during the flux process. Tap holes were located at different levels in the furnace to
filter the minerals and rocks (including copper, iron and slag rock). The tap hole for the iron and slag
rock was located higher than the copper tap hole. The iron and slag rock collected from this filtration
was considered waste. The copper mineral was collected and loaded into box cars for shipment to a
copper refinery. (URS 1993)
Because gold is heavy, it settled to the bottom of the furnace and formed a gold matte. After the
gold accumulated to a thickness of 14 inches, the furnace was shut down. Once the furnace and materials
cooled, the sides of the furnace were removed to gain access to the gold matte, which was then pried
from the furnace and cut into pieces before being loaded into box cars and shipped to a gold refinery.
(URS 1993)
The lead smelter used a process more sophisticated than that used in the copper and gold process
of the previous decade, although a large quantity of sulfur (approximately 30 tons per day) was still being
discharged into the air. Filters for the smokestacks were added later. (URS 1993)
In the days of the copper and gold smelter, two large steam engines, fueled by coal, provided
power. Both flywheel steam engines were hooked onto one long line shaft. On the other end of the line
shaft, a dynamo produced 10,000 volts of electricity prior to being boosted by a generator that provided
up to 100,000 volts. Once the smelter reopened to process lead ores, a high-voltage line from Canada
supplied the power, and the steam plant was shut down. (URS 1993)
The abandoned and dismantled smelter remained inactive after closure in 1922. The town of
Northport demolished the buildings for the usable brick. One building retained enough walls to provide
an ice-skating rink during the winter. The railroad was abandoned and the tracks salvaged. (URS 1993)
The smelting operations produced a tailings waste referred to as slag. The slag was usually
placed in piles near the smelter for temporary or permanent disposal. Historical photographs indicate
possible tailings piles located on the northeast portion of the property. The COCs in the slag are arsenic,
copper, lead, mercury, and zinc.
SSF Building Materials, when operational, was one of the largest businesses in Northport,
employing from 18 to 25 people. The entire site was used for the mill. The southern half of the property
maintained the main lumber operations. The northern half, which contained the smelter remnants, was
used to store lumber products and old metal parts such as cars, piping, and roofing. The lumber mill
10:START-2\01020028\S759
6-32
-------
processed mostly cedar wood from rough-dimension lumber into exterior siding and exterior paneling.
The mill process included cutting the wood, drying the cut wood, and shipping it. Mill operations were
run on propane. All water used for the mill operations was obtained from the city water supply. The mill
did not discharge to or collect water from the Columbia River. (URS 1993)
The scrap wood materials, including sawdust, were sent to Kettle Falls for the Kettle Falls Water
Power Company, which burned the material for energy. Originally, the lumber mill burned the scrap
wood on site inside a wigwam burner. No wood treatment or chemical use is reported in the past mill
operations. (URS 1993)
Environmental concerns in the Northport area have been investigated since 1925. In 1925, the
area became involved in the first international case concerning air pollution. The Washington State
Department of Health and Ecology conducted an investigation of the furan and dioxin reported in the
Columbia River. A PA and SI was conducted by the EPA in 1993. The site inspection stated antimony,
arsenic, copper, and lead were potentially deposited on site as a result of the former smelter operations,
as they were detected on site at significant concentrations. (URS 1993)
Ecology sampled soil and slag piles at the LeRoi/Northport Smelter in 1997. Sample results
showed levels of metals two or three orders of magnitude above background. Concentrations of up to
1,010 mg/kg arsenic; 337 mg/kg cadmium; 33,400 mg/kg copper; 20,200 mg/kg lead; and 1,750 mg/kg
zinc were detected (Gregory 2000a). Ecology planned to conduct a groundwater investigation at the site;
however, due to availability of resources, this has not been pursued (Gregory 2000b).
6.16.4 START-2 Smelter Visit
On June 29 and September 13, 2001, the START-2 visited the LeRoi/Northport Smelter and
conducted a visual inspection of the property and surrounding area (Figure 6-16; Appendix A, Photos
33-1 through 34-4, 42-1 through 42-8, 46-4 through 46-10; Appendix B, Boat Team, Pages 13 through
17; Team 1 Phase 2, Page 15; Team 2 Phase 2, Pages 20 through 22). The START-2 and EPA personnel
observed areas of black glassy sand-like material along the bank of the Columbia River. A public boat
launch is located directly over this material. The ST ART -2 characterized the material as slag. Sediment
samples were collected at the Columbia River from locations near the boat launch and sand bar/beach
area.
On September 13, 2001, the START-2, the EPA TM, Don Hurst of Fulcrum Environmental, and
the property owner conducted a walk-thro ugh of the property. An area where slag bricks had been
deposited was observed south of the former smelter operations. A potential former tailings pile was
10:START-2\01020028\S759
6-33
-------
observed west of the slag brick area. City water wells were observed on the former LeRoi/Northport
Smelter property. The START-2 collected sediment and soil samples from locations on the property.
Water samples were not collected from the City supply wells because local officials did not grant EPA
permission to access the wells to collect samples.
6.16.5 Sampling Locations
Sample locations are depicted in Figures 6-17 and 6-18. Three surface soil samples (NSSL01SS
through NSSL03SS) were collected west of the former tailings area underneath the slag bricks. The
samples were collected within the overland surface water drainage routes identified by the START-2.
The samples were collected to determine potential contamination associated with this source. The
samples appeared to consist of very fine to medium grained sand with sandy reddish slag and yellowish
stain. No odor was noted during sample collection.
Nine sediment samples (NSSL01SD through NSSL09SD) were collected from slag areas along
the Columbia River adjacent to the smelter (PPE 3). The samples were collected within the overland
surface water drainage routes identified by the START -2. The samples were collected to determine
potential contamination associated with this source in the Columbia River. The samples appeared to
consist of dark brown to black medium sand. No odor or staining was noted during sample collection.
Sediment sample NSPP01SD was collected at the confluence of the former tailings pile and the
ditch (PPE 1). The sample appeared to consist of saturated, light brown silt. No odor or staining was
noted during sample collection
One sediment sample (NSDT01SD) was collected in the western portion of a recently
constructed ditch where the former tailings pile potentially was located (PPE 2). The sample was
collected within the overland surface water drainage routes identified by the ST ART -2. The sample was
collected to determine whether potential contamination associated with the tailings pile is migrating to
surface water. The sample appeared to consist of light brown sand fine to medium coarse grained. No
odor or staining was noted during sample collection.

6.17.2 Historical Information
The Black Rock Mine/Mill is a former lead and zinc mine/mill located in the Northport mining
district, Washington (Derkey et al. 1990). The mine produced six carloads of ore prior to 1920 and
5,280 tons of ore between 1922 and 1924 (Derkey et al. 1990). Total production was 140,856 pounds of
lead; 7,903,447 pounds of zinc, and 377 ounces of silver (Derkey et al. 1990). A newmill was built in
1923 (Battien 1998). The mine was still producing in 1943, but no production results are available
(Battien 1998). By 1964 the mine/mill was under option to American Zinc (Battien 1998). Historical
ownership from 1964 to the present is unknown.
6.17.3 Mine/Mill Description/Features
The Black Rock Mine/Mill is situated on the east side of Deep Creek, 6 miles northeast of
Northport, Washington. The property consists of seven claims and seven acres of deeded land. Ore
occurs disseminated along bedding planes in white, nonsilicified dolomitic marble. Two ore bodies,
indicated by drilling, appear to have moderate ore reserves with an average grade of 8% zinc. The
property is developed by a 250-foot incline, 260-foot adit, and considerable drifting and stoping.

6.18.2 Historical Information
The Great Western Mine is a former lead and zinc mine located six miles from Northport,
Washington, one and one half miles off Deep Creek Road, near Black Rock and Last Chance mines/mills
(Derkey et al. 1990; Battien 1998). The mine produced $40,000 prior to 1917 (Derkey et al. 1990).
Total production was 434,072 pounds of lead, 125 ounces of silver, 936,524 pounds of zinc (Derkey et al.
1990). In 1943, the mine was owned by L.J. Magney (Battien 1998). Historical ownership information
from the time reported to the present is unknown.
6.18.3 Mine Description/Features
The Great Western Mine is in the middle dolomite unit of the Metaline Formation
(Derkey et al. 1990). The mine consists of two claims known as Great Western and Empire. The ores
are chiefly carbonate of zinc with some carbonate of lead, together with a subordinate amount of galena
and sphalerite (Weaver 1920). The known length of the mineralized zone is 1,000 feet. The mine is
developed by 1,000 feet of adits and about 200 feet in 3 shafts. (Huntting 1956)

6.19.2 Historical Information
The Last Chance Mine/Mill is a former lead, silver, and zinc mine/mill located 5 miles southeast
of Northport, Washington (Derkey et al. 1990; E & E 2000). From Northport, the mine/mill is accessed
via Colville-Aladdin Northport Road, which runs on the west side of the property (E & E 2000). The
mine/mill is reported to have produced $600,000 prior to 1937 (Derkey et al. 1990). One carload of ore
was shipped in 1938 and small amounts of concentrate were shipped between 1947 and 1949
(Derkey et al. 1990). Between 1904 and 1954, the mine/mill produced 5,937,708 pounds of lead;
18,567 pounds of silver; and 110,110 pounds of zinc (Derkey et al. 1990). The construction of the
floatation mill is reported to have begun in 1940 ( E & E 2000). Juniper Lead Company owned the
mine/mill from 1907 to 1926 (E & E 2000). Reports indicate that in 1938 the property was owned by
Mrs. A. Baker, the widow of the previous owner Al Baker (E & E 2000). Last Chance Consolidated
Mines, Inc., was listed as the owner since 1948 (Battien 1998). Historical ownership information from
1948 to the present is unknown.
6.19.3 Mine/Mill Description/Features
The Last Chance Mine/Mill consists of three patented claims and a mill site (Huntting 1956).
The mine is in the middle dolomite of the Metaline Formation (Mills 1977). Ore shoots occur in a
mineralized shear zone in dolomite, especially at fracture intersections. The zone is as much as 5 feet
wide (Huntting 1956). Two distinct veins are remarkably uniform in strike and dip over a combined
strike length of 650 feet and a dip length of at least 500 feet. The veins are emplaced along faults and
10:START-2\01020028\S759 6-40
-------
appear parallel or sub-parallel to bedding (Mills 1977). The property is developed by four adits, more
than 1,000 feet in open cuts and trenches, and a 60-ton gravity-floatation mill (Huntting 1956).
6.19.4 START-2 Mine/Mill Visit
On June 20, 2001, the START -2 visited the Last Chance Mine/Mill and conducted a visual
inspection of the property and surrounding area (Figure 6-23; Appendix A, Photos 16-14 through 17-22;
Appendix B, Team 1 Phase 1, Pages 13 and 14). The mine/mill area consisted of two waste rock piles.
The larger pile was located north of the north shaft and measured 1,320 feet by 75 feet by 2 feet deep.
The smaller waste rock pile was located west of the north shaft and measured 75 feet by 45 feet by
unknown depth. A tailings pile surrounding a former house or office and mill building was located west
of the waste rock piles and measured 600 feet by 105 feet by 3 feet deep. East of the waste rock piles and
the abandoned road the ST ART -2 located a north and south shaft and an adit upgradient from the north
shaft. A seep was located near the mouth of the south shaft which flows into the unnamed creek. Further
east of the shafts, an unnamed creek was documented. The shaft discharge flowed into the unnamed
creek (PPE 1) and continued west past the waste rock piles, through the tailings pile (PPE 2) and
infiltrated the ground prior to reaching the Colville-Alladin Northport Road. South of the point of
infiltration, a drainage ditch and culvert were observed. The potential flow from the culvert travels by
sheet flow into Deep Creek. Access to the mine/mill is unrestricted. No logging or grazing was noted in
the mine/mill area.
6.19.5 Sampling Locations
Sample locations are depicted in Figure 6-24. Three waste rock samples (LCWP01SS through
LCWP03SS) were collected from the larger waste rock pile located north of the north shaft. The samples
were collected within the overland surface water drainage routes identified by the ST ART -2. The
samples were collected to determine potential contamination associated with this source. The samples
appeared to consist of dry, brown, fine sand/silt. No odor or staining was noted during sample collection.
Three tailings samples (LCTP01SS through LCTP03SS) were collected from the tailings pile
located near the former mill building. The samples were collected within the overland surface water
drainage routes identified by the START-2. The samples were collected to determine potential
contamination associated with this source. The samples appeared to consist of brown-orange fine

6.20.3 Mine Description/Features
The Deep Creek Mine is located approximately 100 yards from the west bank of Deep Creek.
Mineralization occurs in the Metaline Formation (Derkey et al. 1990). The mine was operated from
approximately 1944 to 1956, when the mine was shut down (E & E 2000). The maximum depth of
development was 850 feet bgs. According to tabulations in 1958, the following quantities of metals were
obtained from a total ore production of 763,307 tons: 24,000 pounds of copper; 69 ounces of gold;
15,000,000 pounds of lead; 36,000 ounces of silver; and 66,000,000 pounds of zinc (E & E 2000). The
mine was closed in 1956 due to a combination of factors including a shaft fire, rising mining costs, and
declining metal prices (E & E 2000). Following the closure, the headframe, hoisting, pumping, and other
machinery were removed, and the mine was allowed to flood to within several feet of the shaft collar.
(E & E 2000)
6.20.4 START-2 Mine Visit
On June 20, 2001, the START -2 visited the Deep Creek Mine and conducted a visual inspection
of the property and surrounding area (Figure 6-25; Appendix A, Photos 21-21 through 24-8; Appendix B,
Team 2 Phase 1, Pages 6 and 7). The mine area consisted of four waste rock piles. Waste rock pile 1
located adjacent to Deep Creek measured 20 feet by 20 feet by 5 feet deep. There could be potential
overland flow from waste rock pile 1 to Deep Creek (PPE 1). The flow of Deep Creek was estimated by
the START-2 at 100 cfs. Waste rock pile 2 located adjacent to the main road measured 60 feet by 20 feet
by 10 feet deep. Waste rock pile 3 located west of the pad with power tower and fence measured
100 feet by 30 feet by 10 feet deep. Waste rock pile 4 located near an adit on the south end of the
property measured 40 feet by 20 feet by 5 feet deep. The roads on the mine property were comprised of
waste rock. The entrance road measured 700 feet by 20 feet by 2 feet deep. The road heading south to
the adit measured 400 feet by 15 feet by 2 feet deep and also consisted of tailings. Tailings were found
scattered throughout the mine area. Concentrated areas were located in two on-site wet areas (one on the
south end of the property near the adit measuring 15 feet by 15 feet and one south of the main entrance
road measuring 30 feet by 30 feet) and north and west of waste rock pile 2 adjacent to the entrance road.
A swampy area was located south of the gated entrance and measured 150 feet by 100 feet. There could
be potential flow from this swampy area to Deep Creek (PPE 2). The pad with power tower and fence
10:START-2\01020028\S759

10:START-2\01020028\S759 6-47
-------
No. 2. The property is developed by a lower tunnel driven for a distance of 221 feet, an upper tunnel
driven for a distance of 285 feet, and a 20-foot shaft (Weaver 1920). The veins range up to 30 feet wide
and a low-grade ore body was reported to be 40 feet wide and 500 feet long (Derkey et al. 1990). The
ore deposit occurs along the contact between limestone and an intrusive dike (Huntting 1956).
6.21.4 START-2 Mine Visit
On June 19, 2001, the START -2 visited the Copper King Mine and conducted a visual inspection
of the property and surrounding area (Figure 6-27; Appendix A, Photos 15-6 through 15-20; Appendix B,
Team 1 Phase 1, Pages 8 through 10). The mine area consisted of two waste rock piles. One waste rock
pile was located east of Alladin Road and southwest of adit 1 and measured 60 feet by 30 feet by 3 feet
deep. Adit 1 measured 5 feet by 10 feet. No flow or drainage was noted by the ST ART-2. Adit 2 was
located east of adit 1 and measured 5 feet by 10 feet. Adit drainage flowed approximately 75 feet
southwest before infiltrating the ground. There is a potential that during heavy flow adit 2 discharge
could reach Deep Creek (PPE 1). A retention area was documented where the adit discharge infiltrates
the ground measuring 5 feet by 1 feet by 1 feet deep. The retention area was composed of small logs and
plastic sheeting which was estimated to retain approximately 15 gallons. A hose was noted south of the
retention area extending southwest for approximately 20 feet. To the east of adit 2 the START-2
identified a second waste rock pile and shaft. The waste rock pile measured 75 feet by 120 feet by 6 feet
deep. The shaft was surrounded by the waste rock and measured 15 feet by 20 feet by unknown depth.
Standing water was noted. No buildings or evidence of buildings were noted on the property. Access to
the mine is unrestricted and the START-2 noted recent logging. The START-2 also noted grazing in the
area near adit 2.
6.21.5 Sample Locations
Sample locations are depicted in Figure 6-28. Two waste rock samples (CKWPOlSSand
CKWP02SS) were collected from the waste rock pile surrounding the shaft on the northeast portion of
the property. The samples were collected within the overland surface water drainage routes identified by
the START-2. The samples were collected to determine potential contamination associated with this
source. The samples appeared to consist of fine orange and brown sand with trace gravel and pyrite. No
odor or staining was noted during the sample collection.
One surface water sample was collected from the discharge of water originating at adit 2
(CKAD01SW). The sample was collected within the overland surface water drainage route identified by

6.22.2 Historical Information
The Sierra Zinc Mine/Mill is a former gold, lead, silver, and zinc mine/mill off Colville-Alladin
Northport Road, south ofNorthport, Washington (Derkey et al. 1990). Sierra Zinc, sometimes called
Aladdin or Blue Ridge included eight claims and 180 acres of deeded ground (Battien 1998). The
mine/mill was located on the west side of Deep Creek and approximately 4 miles north of Aladdin or
17 miles south of Northport (Battien 1998). The mine is reported to have produced in 1909, 1924, 1925,
1941 through 1944, and between 1950 and 1952 (Derkey et al. 1990). A mill was built in 1942 (Battien
1998). In 1924 and earlier, some development work was performed by T.R Roberts (Battien 1998).
Amos E. Huseland filed claims for part of the mine in 1935 (Battien 1998). Other owners include T.C.
Higginbotham, Goldfield Consolidated, Tri-Nite, and Coronado. Higginbotham sold the mill to
Goldfield Consolidated in 1948 and then bought it back in 1960 (Battien 1998). Tri-Nite purchased the
mill in 1962 (Battien 1998). Coronado leased the property with an option to purchase from Tri-Nite in
1972 (Battien 1998). Additional historical ownership from 1972 to the present is unknown.
6.22.3 Mine/Mill Description/Features
The Sierra Zinc Mine/Mill consists of seven claims. Alternative names include Alladin Mine
and Blue Ridge Mine. The ore deposit consists of galena and sphalerite disseminated in limestone.
Quartz veins carry minor amounts of chalcopyrite, galena, molybdenite, pyrite, and sphalerite. The main
ore body mined prior to 1944 measured 300 feet along the strike, 200 feet along the dip, and 4 to 12 feet
thick. Three smaller ore bodies were mined. The property is developed 8,450 feet in three adits, a
470-foot shaft, and a 300-ton floatation mill. (Huntting 1956)
6.22.4 START-2 Mine/Mill Visit
On June 21, 2001, the START -2 visited the Sierra Zinc Mine/Mill and conducted a visual
inspection of the property and surrounding area (Figure 6-29; Appendix A, Photos 24-10 through 28-2;
Appendix B, Team 2 Phase 1, Page 8 and supplemental pages supplied by Guy Gregory of Ecology).
The property was accessed by Colville-Aladdin Northport Road. The mine/mill area consisted of one
10:START-2\01020028\S759
6-50
-------
waste rock pile measuring 100 feet by 50 feet by 5 feet deep. North of the waste rock pile was a tailings
pile measuring 1,000 feet by 2,100 feet by an estimated 20 feet deep. There could be potential overland
flow from the tailings pile to a drainage ditch (PPE 1) located east of the tailings pile. The flow of the
drainage ditch was estimated by the START-2 to be approximately 0.5 cfs. A mill building was located
south of the waste rock pile and tailings pile measuring 250 feet by 225 feet. Northwest of the mill
building an adit was located measuring 2 feet by 2 feet by unknown depth. The discharge was estimated
by the START-2 at approximately 0.5 gallons per minute (gpm). The adit water flowed north into the
forested area. Three residences were located south of the property. A fence was noted along a portion of
the tailings pile; however, gaps were present in the northern fence line. A road with a no trespassing sign
was noted which continued to the southern end of the tailings pile and mine/mill area where several
houses were located. No fence was observed. No logging or grazing was noted in the vicinity of the
property.
6.22.5 Sampling Locations
Sample locations are depicted in Figure 6-30. Twelve waste rock samples (SZWP01SS through
SZWP12SS) were collected from the waste rock pile. The samples were collected within the overland
surface water drainage routes identified by the START -2. The samples were collected to determine
potential contamination associated with this source. The samples appeared to consist of gray, fine, dry
sand. No odor or staining was noted during sample collection.

6.29.2 Historical Information
The Red Top Mine is a former lead, silver, and zinc mine located in the Northport mining
district, Washington (Derkey et al. 1990). The mine is reported to have produced approximately 200 tons
of ore prior to 1939 (Derkey et al. 1990). The mine also is reported to have produced in 1944 and 1953
(Derkey et al. 1990). From 1952 to 1954 the Pacific Northwest Mining Company was listed as the owner
(Battien 1998). By 1962, the Red Top Company leased the mine to Rare Metals Corporation
(Battien 1998). Historical ownership information from 1962 to the present is unknown.
6.29.3 Mine Description/Features
The Red Top Mine consists of five patented and three unpatented claims (Huntting 1956).
Mineralized shear zones are in marble and argillite and are crisscrossed by quartz veins. Some ore shoots
are as much as 4 feet wide and 18 feet long. Four separate mineralized zones, as much as 1 foot wide, cut
across bedding. The ore minerals in these transverse zones include galena, pyrite, scheelite, and
tetrahedrite (Derkey et al. 1990). The mine is developed by a 2,700-foot adit and approximately 1,500
feet of drifts and raises (Huntting 1956).
6.29.4 START-2 Mine Visit
On June 26, 2001, the START -2 visited the Red Top Mine and conducted a visual inspection of
the property and surrounding area (Figure 6-35; Appendix A, Photos 14-11 through 14-20; Appendix B,
Team 1 Phase 1, Pages 3 through 5). The mine area, which is accessed via an unimproved road,
contained a waste rock pile measuring 200 feet by 150 feet by 10 feet deep. An adit, measuring 5 feet by
5 feet by unknown depth, is located north of the waste rock pile and unimproved road. Wooden debris,
measuring 10 feet by 15 feet, was noted west of the waste rock pile and south of the unimproved road. A
portal/shaft, measuring 10 feet by 5 feet, is located west of the adit. No discharge was observed from the

-------
Andy Anderson discovered mineralization in 1910 and explored it with shallow pits and trenches
(Mills 1977). During World War II, the United States Bureau of Mines drilled several holes as part of
the Defense Minerals Program (Mills 1977). Goldfield Consolidated acquired the mine/mill, the date
unknown, and mined by open-pit the area prospected by Anderson, drilled out a portion of the ore body
adjacent to the pit, and initiated mechanized development (Mills 1977). American Zinc Lead and
Smelting Company purchased the mine/mill from Goldfield Consolidated in 1964 and entered into
production in 1966 (Battien 1998; Mills 1977). By 1965-1966, a 1,200 ton floatation mill for lead, silver,
and zinc had been built (Battien 1998). In addition to the floatation mill, another mill, shops, and
warehouses were constructed (Battien 1998). The mine/mill operated until 1968 (Derkey et al. 1990).
The mine/mill closed because of depressed metal prices and diminishing ore reserves after extraction of
nearly a million tons of ore (Mills 1977). Historical ownership information from 1968 to the present is
unknown.
6.30.3 Mine/Mill Description/Features
The Anderson Calhoun Mine/Mill is situated on the west side of Deep Creek approximately
1 mile north of Leadpoint. The mine/mill lies in the middle dolomite unit of the Metaline Formation.
Ore minerals occur disseminated in limestone. The ore bodies range up to 80 feet wide, 80 feet high, and
650 feet long (Derkey et al. 1990). Production is from open pit mining. (Huntting 1956)
6.30.4 START-2 Mine/Mill Visit
On September 11 and 13, 2001, the START-2 visited the Anderson Calhoun Mine/Mill and
conducted a visual inspection of the property and surrounding area (Figure 6-37; Appendix A, Photos

mine building, the floatation building, and the waste rock storage bin. The mine building measured
25 feet in width by 15 feet in length by 20 feet in height. The conveyor belt attached to the floatation
building measured 35 feet in length. The floatation building measured 25 feet in width by 15 feet in
length by 10 feet in height. The waste rock storage bin measured 15 feet in width by 15 feet in length by
40 feet in height.
The mill building was located north of the mine building and measured 50 feet in width by
75 feet in length by 40 feet in height. The mill building contained staged reagent and unknown drums,
floatation tanks, and a crusher. Approximately 100 55-gallon steel drums were staged in the east corner
of the mill building. Many of these unmarked drums were punctured with bullets with the contents
spilling onto the concrete foundation. The unknown spilled contents were solidified. The concrete floor
did not appear to be breached. Tailings were scattered throughout the mill building. A portal measuring
10 feet by 10 feet was located on the western portion of the mill building with a conveyor belt leading
into the building.
A first aid room of wood construction was located southwest of the mill building and adjacent to
the conveyor belt extending from the portal/shaft. The first aid room measured 8 feet in width by 10 feet
in length by 12 feet in height. The conveyor belt extending from the portal/shaft appeared to connect
with the mine building at one point, measuring approximately 110 feet in length.
Remnants of a storage shed and two concrete pads were located between the mine and mill
buildings. The storage shed foundation measured 20 feet by 20 feet. Remnants of "Cebar Barite", a
white cellulose-type material, was scattered throughout the storage shed foundation and surrounding area
including the concrete pads. Five 55-gallon drums were scattered on the storage shed foundation. One
concrete pad measuring 40 feet by 10 feet was located directly east of the dilapidated storage shed. Ten
55-gallon drums were staged on palettes. There was no legible documentation on the drums. The second
concrete pad was located north of the first concrete pad and measured 10 feet by 20 feet. Scrap wood,
steel, and garbage were scattered on both concrete pads.
On the north side of the mill building, three areas of scattered drums intermixed with debris and
equipment were documented. Stained soil with an oil odor were noted around the drums. Cattle prints
were identified in the stained soil. There was a distinct sheen throughout the stained soil area
surrounding the drums.
Transformers were identified in 6 areas. A substation, heavily vandalized, also was documented.
The first area was located east of the dilapidated storage shed and two concrete pads and included a
power line with three transformers. The second area was located adjacent to the south side of the mill

upper slope consisted of four shed-like buildings, an adit, and a power pole (Appendix A, Photos 44-1,
44-2, 44-3, and 44-12). Approximately 4 inches of ponded water was observed in the adit. The adit was
not flowing at the time of the visit and sand bags were observed at the opening of the adit (Appendix A,
Photos 44-4 and 44-11). The area in front of the adit was wet with shallow ponded water for
approximately 10 feet. The middle slope consisted of a mill, a collapsed building, tailings, and a waste
rock pile (Appendix A, Photos 44-5 through 44-8, 44-10 and 44-14). The mill building measured 15 feet
by 15 feet by 25 feet. The tailings at the middle slope were observed to be very fine and silty. The lower
slope consisted of finer tailings. The tailings measured 60 feet by 45 feet by unknown depth. At the
bottom of the lower slope, the road slopes downward to a point where most run-off from the mine
property would flow. At this location is a pump shed with four round concrete structures (Appendix A,
Photo 44-13). The START-2 did not observe any overland drainage routes from the adit, tailings, or
waste rock pile to surface water. Access to the mine was unrestricted. No residents or potential
receptors were observed on the property. No samples were collected at the Silver Queen Mine.

6.34.2 Historical Information
The Melrose Mine is a former copper, lead, silver, and zinc mine located 4 miles south of
Boundary, Washington (Derkey et al. 1990). The mine is reported to have produced between 1913 and
1938 (Derkey et al. 1990). The total yield from 97 tons of ore was 1,255 pounds of copper,
11,176 pounds of lead, and 2,973 ounces of silver (Derkey et al. 1990). Charleston Resources Ltd. took
over the property in 1977 (Battien 1998). Historical ownership information from 1977 to the present is
unknown.
6.34.3 Mine Description/Features
The Melrose Mine ore deposit consists of a 6-foot vein in argillite containing irregular scattered
bunches of ore. Ore minerals include galena, sphalerite, and tetrahedrite. The mine is developed by
1,600 feet of underground workings. (Huntting 1956)
6.34.4 START-2 Mine Visit
On June 18, 2001, the START-2 visited the Melrose Mine and conducted a visual inspection of
the property and surrounding area (Figure 6-41; Appendix A, Photos 14-1 through 14-7; Appendix B,
Team 1 Phase 1, Pages 2 and 3). The mine area consisted of an adit 5 feet by 10 feet by unknown depth.
Moss and algae growth were noted near the mouth of the adit. The adit discharge flowed approximately
40 feet east to an unnamed tributary (PPE 1) that feeds into Tom Bush Creek. The ST ART-2 estimated
the flow of the unnamed tributary at 1 gpm. There were no waste rock piles; however, the entry road
appeared to be constructed out of waste rock. A building approximately 10 feet by 10 feet by 10 feet was
10:START-2\01020028\S759 6-72
-------
located to the north of the adit and contained test core samples. Access to the mine was unrestricted and
the START-2 noted garbage left by visitors. No logging or grazing was noted in the vicinity of the mine.
6.34.5 Sample Locations
Sample locations are depicted in Figure 6-42. One surface water sample was collected from the
discharge of water originating at the adit (MLAD01SW). The sample was collected within the overland
surface water drainage route identified by the START-2. The sample was collected to determine
potential contamination associated with this source. The sample was clear. No odor or staining was
noted during sample collection.
One sediment sample was collected at the confluence of the adit water drainage to the unnamed
tributary (PPE 1; MLPP01SD). The sample appeared to consist of brown sand with trave gravel and
organics. No odor or staining was noted during sample collection.
6.34.6 Analytical Results
6.34.6.1 Surface Water Sample Results
Analytes detected in water collected at the adit include zinc at an estimated concentration of
433 /ig/L.
6.34.6.2 Sediment Sample Results
The START-2 collected one sediment sample from the PPE for TAL metals analyses. Cadmium
was detected at an elevated concentration of 22.8 mg/kg and zinc was detected at an elevated
concentration of 1,650 mg/kg. Refer to Table 6-25 for complete data results.

7. EPA CLP ANALYTICAL RESULTS, SURFACE WATER
MIGRATTON/EXPOSUREPATHWAYS, AND TARGETS
The following sub-sections describe the surface water migration pathways for the 18 mines/mills
that were sampled, tributaries that were sampled, potential targets within the range of influence of these
mines/mills (Figures 7-1 through 7-18), and a discussion of sample results evaluated in accordance with
criteria described in Section 5.1. Analytical data forms from laboratory analyses are provided in
Appendix D.
With the exception of the LeRoi/Northport Smelter and Deep Creek Mine, an evaluation of the
groundwater migration, soil exposure, and air migration pathways for all mine/mill sites sampled was not
conducted as part of this investigation. Additional to an evaluation of the surface water migration
pathway, an evaluation of the soil exposure pathway also was conducted as part of the investigations at
the LeRoi/Northport Smelter and Deep Creek Mine.
Refer to Table 7-1 for alist of PPEs for those sampled mines/mills that contained a PPE.
7.1 DAISY MINE
7.1.1 Surface Water Pathway Description
The potential source areas at the Daisy Mine include a tailings pile measuring approximately
150 feet at the base, 30 feet in height with a slope of approximately 35%, and a depth of approximately
45 feet, and a shaft. The shaft measured 10 feet by 10 feet by unknown depth. A wet area originating
from the shaft extended south approximately 25 feet. From this source area, it is approximately another
70 feet overlandto Magee Creek (PPE 1; Figure 6-1).
From the source area, drainage flows overland approximately 50 feet to the PPE in a ditch. The
surface water target distance limit (TDL) continues approximately 0.08 mile in the ditch to an unnamed
tributary. The unnamed tributary empties to Magee Creek 2.95 miles downstream. Magee Creek empties
into the Columbia River another 2.18 miles downstream. The surface water TDL concludes 9.79 miles
downstream in the Columbia River.
10:START-2\01020028\S759
7-1
-------
The unnamed tributary is assumed to be a minimal stream with flow rates less than 10 cfs.
Magee Creek is assumed to be a small to moderate stream with flow rates between 10 cfs and 100 cfs.
Columbia River at the U.S.-Canada border is 116,500 cfs (USGS2002).
The average annual precipitation is 17.20 inches in Colville, Washington (WRCC 2002). The
2-year, 24-hour rainfall event for the area ranges from 1.4 to 2.0 inches (NOAA 1973).
Soils in the area of Daisy Mine were mapped as Dehart-Rock outcrop complex, 40 to 65 percent
slopes on side slopes and foothills. The Dehart soil is very deep and somewhat excessively drained. The
permeability of the soil is moderately rapid, and the available water capacity is low. Runoff is very
rapid, and the hazard of water erosion is very high. (USDA 1982)
Approximately 279 upgradient acres of land is expected to drain through the source area at the
mine (USGS 1985). The drainage area of sources is approximately 1 acre (USGS 1985).
The Daisy Mine does not lie in a flood plain (FEMA 1990).
No containment features such as runoff controls exist at the property.
7.2 L- B AR/N O RIH W ES T MAGNESITE
7.2.1 Surface Water Pathway Description
The potential source areas at L-Bar/Northwest Magnesite include an above-grade magnesite
residue pile, approximately 30 feet deep and 17 acres in area, and inadequate storage of flux bar and flux
bar residue. The magnesite pile is adjacent to the Main Ditch which flows into the Colville River
approximately 1,000 feet north of the confluence of the magnesite pile and the Main Ditch (Figure 6-3).
For the magnesite and flux bar residue pile, the PPE is located in the West Ditch. The overland
distance between the source area and the West Ditch is less than 50 feet. The West Ditch flows
approximately 0.32 mile to the confluence with the Colville River. The surface water TDL concludes
14.68 miles downstream in the Colville River. The magnesite and flux bar residue pile also used to drain
through the Main Ditch, but a water retention system has been installed in the ditch to eliminate
discharge to the Colville River.
The West Ditch is assumed to be a minimal stream with a flow rate less than 10 cfs. The average
annual flow rate of the Colville River near Blue Creek is 110 cfs (USGS 2002).
The average annual precipitation is 17.20 inches in Colville, Washington (WRCC 2002). The
2-year, 24-hour rainfall event for the area ranges from 1.4 to 2.0 inches (NOAA 1973).
Soils in the area of L-Bar/Northwest Magnesite were mapped as Colville silt loam, drained in
bottom lands. The Colville soil is very deep, artificially drained soil. The permeability of the soil is
10:START-2\01020028\S759

moderately slow, and the available water capacity is very high. Runoff is very slow, and there is no
hazard of water erosion. (USDA 1982)
Approximately 200,000 upgradient acres of land is expected to drain through the source area at
the mine (USGS 1984). The drainage area of sources is approximately 16 acres (USGS 1984).
L-Bar/Northwest Magnesite lies within a 100-year flood plain (FEMA 1990).
Containment features such as runoff controls exist at the property.
7.3 NORTHWEST ALLOYS
7.3.1 Surface Water Pathway Description
The potential source areas at Northwest Alloys include products and byproducts in the
production of magnesium, silicon, and ferrosilicon. Waste products generated were either recycled, sold
as product or thread, or buried on site. None of the wastes were regarded as hazardous under RCRA but
were classified as regulated wastes under Ecology Dangerous Waste Regulations (E & E 1988). There is
no overland flow from the site directly into the Colville River due to topography. A potential overland
flow exists on the southern portion of the site. The overland flow potentially flows through ditches into
Stensgar Creek (PPE 1). Stensgar Creek flows into the Colville River (Figure 6-5).
The average annual precipitation is 17.20 inches in Colville, Washington (WRCC 2002). The
2-year, 24-hour rainfall event for the area ranges from 1.4 to 2.0 inches (NOAA 1973).
Soils in the area of Northwest Alloys were mapped as Colville silt loam, drained; Donavan loam,
8 to 25 percent slopes; Hodgson silt loam, 3 to 15 percent slopes; Koerling fine sandy loam, 5 to 15
percent slopes; Martella silt loam, 0 to 5 percent slopes; Martella silt loam, 5 to 15 percent slopes; Rock
outcrop-Donavan complex, 30 to 65 percent slopes; and Springdale gravelly sandy loam, 0 to 15 percent
slopes. The Colville silt loam, drained, is very deep, artificially drained soil on bottom lands. The
permeability of the soil is moderately slow, and the available water capacity is very high. Runoff is very
slow, and there is no hazard of water erosion. The Donavan loam, 8 to 25 percent slopes is very deep,
well drained soil on toe slopes and foot slopes of foothills. The permeability of the soil is moderate, and
the available water capacity is high. Runoff is medium, and the hazard of water erosion is moderate.
Hodgson silt loam, 3 to 15 percent slopes is very deep, moderately well drained soil on undulating
terraces. The permeability of the soil is moderately slow, and the available water capacity is very high.
Runoff is slow, and the hazard of water erosion is slight to moderate. Koerling fine sandy loam, 5 to 15

side slopes and foothills. The permeability of the soil is moderate, and the available water capacity is
high. Runoff is very rapid, and the hazard of water erosion is very high. Springdale gravelly sandy loam,
0 to 15 percent slopes is very deep, somewhat excessively drained soil on terraces. The permeability of
the soil is moderately rapid to the layer of extremely cobbly coarse sand. The available water capacity is
low. Runoff is slow, and the hazard of water erosion is slight. (USDA 1982)
From the site, drainage enters a ditch, at PPE 1 for the surface water pathway. The ditch flows
an estimated 0.33 mile before entering Stensgar Creek. The surface water TDL continues 0.79 mile in
Stensgar Creek to the Colville River. The surface water TDL concludes 13.88 miles downstream in the
Colville River.
Stensgar Creek and the ditch are assumed to be minimal streams with flow rates less than 10 cfs.
The average annual flow rate of the Colville River at Blue Creek is 110 cfs (USGS2002).
Approximately 100,000 upgradient acres of land is expected to drain through the source area at
the mine. The drainage area of sources is approximately 79 acres. (USGS 1984)
Northwest Alloys lies within a 100-year flood plain (FEMA 1990).
Containment features such as runoff controls exist at the property.
7.4 NAPOLEON MINE/MILL
7.4.1 Surface Water Pathway Description
The potential source areas at the Napoleon Mine/Mill include an adit measuring 5 feet by 4 feet
located south of the dirt road entrance. The adit discharge flows across the dirt road, down the hillside
approximately 120 feet before entering an intermittent creek (PPE 1; Figure 6-7). The surface water
TDL continues 0.73 mile in the intermittent creek to Kettle River. Kettle River empties into the
Columbia River another 4.39 miles downstream. The surface water TDL concludes 9.88 miles
downstream in the Columbia River.
10:START-2\01020028\S759

-------
The intermittent creek is assumed to be a minimal stream with a flow rate less than 10 cfs. Kettle
River is assumed to be a small to moderate stream with an average flow rate between 10 cfs and 100 cfs.
Columbia River at the U.S.-Canada border has a flow rate of 116,500 cfs (USGS2002).
The average annual precipitation is 19.43 inches in Northport, Washington (WRCC 2002). The
2-year, 24-hour rainfall event for the area ranges from 1.4 to 2.0 inches (NOAA 1973).
Soils in the area of Napoleon Mine/Mill were mapped as Aits stony loam, 40 to 65 percent
slopes. The soil is very deep, well drained soil on side slopes and foothills. The permeability of the soil
is moderately slow, and the available water capacity is very high. Runoff is very rapid, and the hazard of
water erosion is very high. (USDA 1982)
Approximately 525 upgradient acres of land are expected to drain through a source area at the
mine (USGS 1969a). The drainage area of sources is approximately 1 acre (USGS 1969a).
The Napoleon Mine/Mill does not lie in a flood plain (FEMA 1990).
No containment features such as run off control exist at the property.
7.5 VAN S TO NE MINE/MILL
7.5.1 Surface Water Pathway Description
The potential source areas at the Van Stone Mine/Mill include waste rock storage area, two
tailings piles, an open pit, buildings, and stained soil areas (Figures 6-9 through 6-11).
The waste rock storage area was constructed by end dumping to the south contour from the open
pit haul road. The eastern toe of the waste rock storage area consists mostly of larges and is located less
than 100 feet from the Northeast Fork of Onion Creek. Slopes on the north side of the haul road consist,
in part, of colluvial overburden. Depth and quantity of overburden has yet to be determined.
(Beacon 1999)
The tailings embankments consist of steep sided erodable tailings sands. In some locations the
slopes are heavily rilled, particulary along the south and west faces. (Beacon 1999)
A rock-lined spillway and discharge channel has been installed in the extreme northeast corner of
the main tailings impoundment to direct any excess accumulated rainwater to the adjacent drainage.
Tailings area water quality is monitored every 90 days and is reported to be suitable for discharge under
the Water Discharge Permit or can be used for irrigation purposes.
A seepage pond is located adjacent to the tailings facility.
The open pit, located in the most southern portion of the area is flooded to an elevation of
3,510 feet or 170 feet above the current pit bottom. The rim of the open pit and portions of the top bench
10:START-2\01020028\S759

-------
currently support vegetation. The water in the open pit is separated from a tributary to the Northeast
Fork of Onion Creek by a narrow rock-fill berm. The water level in the open pit is static at 3,510 feet
elevation and excess water seeps through this rock-fill to the adjacent creek (PPE 3). (Beacon 1999)
Six areas of stained soil were noted on the property. The first area was near a liquid propane
tank south of the mill building. The second area was near elevated transformers adjacent to the mill
building. At this location, the soil was stained orange and green. The third area was near an AST with
secondary containment near the entrance to the mine/mill. The containment area was filled with water
and smelled of diesel. No sheen was noted. The secondary containment had been breached. The fourth
area was on a concrete pad with staged transformers and stained soil south of the liquid propane tank.
The fifth area was near staged 5 5-gallon drums surrounded by stained soil west of the mine/mill
buildings and south of the Roundup Powder Company abandoned building. The sixth area was near
another AST area surrounded by stained soil located east of the shed and staged 5 5-gallon drums.
Several unnamed creeks were located adjacent to the property. One unnamed creek was located
south of the mine pit water and could not be accessed due to safety concerns. A second unnamed creek
was located at the southwest portion of the old tailings pile (PPE 4). A third unnamed creek was located
on Boise Cascade property; no sample was collected due to lack of access. A fourth unnamed creek was
located adjacent to the tailings pile near the entrance to the mine/mill (PPE 1 and PPE 2). Excess water
from the on-site open pit seeps through the pit berm to an adjacent creek (PPE 3).
A number of public, private, and commercial interests access the mine/mill access road. Boise
Cascade Forest District maintains an easement over the road to access their timber holdings. Washington
Water Power maintains an easement over the road to access a substation located on the mine/mill
property. There are residences near the road junction and the DNRuses the road for fire control.
(Beacon 1999)
For the waste rock and stained soil source areas, drainage flows overland approximately 800 feet
to the PPE in an unnamed tributary. The open pit is located immediately adjacent to this PPE. Excess
water in the pit seeps through the rock berm to the unnamed tributary. From the PPE, the surface water
pathway TDL continues 2.17 miles in the unnamed tributary to the confluence with Onion Creek. Onion
Creek empties into the Columbia River another 8.89 miles downstream. The surface water TDL
concludes 3.94 miles downstream in the Columbia River.
For the tailings pile source area, drainage flows overland approximately 950 feet to the PPE in an
unnamed tributary. From the PPE, the surface water pathway TDL continues 0.90 mile to the

confluence with Onion Creek. Onion Creek empties into the Columbia River another 8.89 miles
downstream. The surface water TDL concludes 5.21 miles downstream in the Columbia River.
For the old tailings pile source area, drainage flows overland approximately 950 feet to the PPE
in an unnamed tributary. From the PPE, the surface water pathway TDL continues 1.14 miles to the
confluence with Onion Creek. Onion Creek empties into the Columbia River another 8.89 miles
downstream. The surface water TDL concludes 4.97 miles downstream in the Columbia River.
The unnamed tributary is assumed to be a minimal stream with a flow rate less than 10 cfs.
Onion Creek is assumed to be a small to moderate stream with flow rates between 10 cfs and 100 cfs.
The Columbia River (or Lake Roosevelt) has a flowrate of 116,500 cfs as measured at the U.S.-Canada
border (USGS 2002).
The average annual precipitation is 17.20 inches in Colville, Washington (WRCC 2002). The
2-year, 24-hour rainfall event for the area ranges from 1.4 to 2.0 inches (NOAA 1973).
Soils in the area of Van Stone Mine/Mill were mapped as Merkel stony sandy loam, 40 to 65
percent slopes; Newbell silt loam, 25 to 40 percent slopes; Newbell stony silt loam, 0 to 40 percent
slopes; and Newbell-Rock outcrop complex, 15 to 40 percent slopes. The Merkel stony sandy loam,
40 to 65 percent slopes is very deep, moderately well drained soil on terrace escarpments. The
permeability of the soil is moderately slow, and the available water capacity is very high. Runoff is very
rapid, and the hazard of water erosion is high. The Newbell silt loam, 25 to 40 percent slopes is very
deep, well drained soil on foot slopes of foothills. The permeability of the soil is moderate, and the
available water capacity is very high. Runoff is rapid, and the hazard of water erosion is high. The
Newbell stony silt loam, 0 to 40 percent slopes is very deep, well drained soil on toe slopes and foot
slopes of foothills. The permeability of the soil is moderate, and the available water capacity is very

(USD A 1982)
Approximately 470 upgradient acres of land are expected to drain through a source area at the
mine (USGS 1969b). The drainage area for the waste rock pile at the site is estimated to be 16 acres
(USGS 1969b).
The Van Stone Mine/Mill does not lie in a flood plain (FEMA 1990).
Containment features such as runoff control exist at the mine pit water at the mine/mill. At
present, the steep outer walls of the tailings piles are subject to surface erosion, as evidenced by the rills
10:START-2\01020028\S759

and gullies developed on the walls. A small berm has been made around the tailings piles to contain
eroded material and is effective in containing eroded material. The owner is testing erosion control
methods on the tailings pile walls. (Boise Cascade Corporation 1997)
7.6 LERO I/NO RIHPORT SMELTER
7.6.1 Surface Water Pathway Description
The potential source areas at the LeRoi/Northport Smelter include an area where slag bricks had
been deposited south of the former smelter operations, and a potential former tailings area west of the
slag brick area. The former tailings pile area was adjacent to a recently constructed ditch (PPE 1;
Figure 6-16).
For the tailings pile, drainage enters a constructed ditch, PPE 1 and PPE 2, for the surface water
pathway. The overland distance between the tailings pile and the ditch is estimated to be less than
100 feet for PPE 2. The tailings pile extends into the ditch at PPE 1. From the PPEs, the surface water
TDL continues approximately 0.05 mile through the constructed ditch, which empties into the Columbia
River. The surface water TDL concludes 14.95 miles downstream in the Columbia River.
The slag pile is located on the shore of the Columbia River (or Lake Roosevelt). The source area
extends into the Columbia River (PPE 3). From PPE 3 the surface water TDL concludes 15 miles
downstream in the Columbia River.
The Columbia River (or Lake Roosevelt) has a flow rate of 116,500 cfs as measured at the U.S.-
Canada border (USGS 2002).
The average annual precipitation is 19.43 inches in Northport, Washington (WRCC 2002). The
2-year, 24-hour rainfall event for the area ranges from 1.4 to 2.0 inches (NOAA 1973).
Soils in the area of LeRoi/Northport Smelter were mapped as Hagen sandy loam, 0 to 15 percent
slopes. The soil is very deep, somewhat excessively drained soil on terraces. The permeability of the
soil is moderately rapid in the upper part and very rapid in the lower part. The available water capacity is
moderate. Runoff is slow. The hazard of water erosion is slight to moderate, and the hazard of wind
erosion is high. (USDA 1982)
Approximately one upgradient acre of land is expected to drain through the source area at the
mine (USGS 1969c). The drainage area of sources is approximately 33 acres (USGS 1969c).
The LeRoi/Northport Smelter lies within a 100-year flood plain (FEMA 1990).

7.6.2 Soil Exposure Pathway Description
A boat launch is located near the slag deposited along the bank of the Columbia River. No
residents are located at the site. No school or day care facility is located within 200 feet of the site.
There are no worker's within 200 feet of any source on site. The LeRoi/Northport Smelter is located
within the city limits of Northport. Based on USGS topographic maps, the START-2 assumes
336 people reside within a 1-mile travel distance from the site. No residents are located at the site. The
nearest residence is located 0.22 miles southwest from the site. No school or day care facility is located
within 200 feet of the site. There are no workers within 200 feet of any source on site. A city park is
located approximately 50 feet from the north boundary of the site. The park is accessed by means of a
road on the southwest corner of the site. Access to the site is not restricted. Sources at the site are not
fenced. No resources such as commercial agriculture, silviculture, or livestock production or grazing
exist on a source area at the site. No wetlands are located on a source area at the site.
7.7 BLACK ROCK MINE/MILL
7.7.1 Surface Water Pathway Description
The potential source areas at the Black Rock Mine/Mill include a waste rock pile, shaft, remnants
of a mill building, and two sorting bins. No PPEs were identified by the START-2 (Figure 6-19).
Although no PPEs exist at the site, the nearest surface water body is Deep Creek, located
approximately 950 feet from the waste rock pile and collapsed mill source areas. From this location, the

7.11 COPPER KING MINE
7.11.1 Surface Water Pathway Description
The potential source areas at the Copper King Mine include two waste rock piles, adits, and a
shaft (Figure 6-27).
One waste rock pile was located east of Alladin Road and southwest of adit 1 and measured
60 feet by 30 feet by 3 feet deep. Adit 1 measured 5 feet by 10 feet. No flow or drainage was noted by
the START-2. Adit 2 was located east of adit 1 and measured 5 feet by 10 feet. Adit 2 drainage flowed
approximately 75 feet southwest before infiltrating the ground. There is a potential that during heavy
flow adit 2 discharge could reach Deep Creek (PPE 1). A retention area was documented where the adit
discharge infiltrates the ground measuring 5 feet by 1 feet by 1 feet deep. The retention area was
composed of small logs and plastic sheeting which was estimated to retain approximately 15 gallons. A
hose was noted south of the retention area extending southwest for approximately 20 feet. To the east of
adit 2 the START-2 identified a second waste rock pile and shaft. The waste rock pile measured 75 feet
by 120 feet by 6 feet deep. The shaft was surrounded by the waste rock and measured 15 feet by 20 feet
by unknown depth. Standing water was noted.
For the waste rock piles and adit 2, drainage will flow overland approximately 475 feet to the
PPE at the South Fork of Deep Creek. The surface water TDL begins in the South Fork of Deep Creek

7.18 MELROSE MINE
7.18.1 Surface Water Pathway Description
The potential source area at the Melrose Mine includes an adit (Figure 6-41).
The mine area consisted of an adit 5 feet by 10 feet by unknown depth. Moss and algae growth
were noted near the mouth of the adit. The adit discharge flowed approximately 40 feet east to an
unnamed tributary (PPE 1) that feeds into Tom Bush Creek. The ST ART-2 estimated the flow of the
unnamed tributary at 1 gpm. The surface water TDL continues for 0.1 mile in the unnamed tributary to
the confluence with Tom Bush Creek. Tom Bush Creek empties into the Columbia River 1.74 miles
downstream. The surface water TDL concludes 13.16 miles downstream in the Columbia River.
There were no waste rock piles; however, the entry road appeared to be constructed out of waste
rock. A building approximately 10 feet by 10 feet by 10 feet was located to the north of the adit and
contained test core samples.
The average annual precipitation is 19.43 inches in Northport, Washington (WRCC 2002). The
2-year, 24-hour rainfall event for the area ranges from 1.4 to 2.0 inches (NOAA 1973).
Soils in the area of Melrose Mine were mapped as Huckleberry silt loam, 15 to 25 percent slopes.
The soils are moderately deep, well drained on toe slopes and ridgetops of mountains. The permeability

7.20 TARGETS
This section discusses potential target information for the 18 mines that were sampled. There are
no schools or day-care facilities within 200 feet of the 18 mine/mill areas that were sampled.
Lake Roosevelt and the upper Columbia River are used for hydroelectric power, irrigation, and
recreation. The man-made Lake Roosevelt area provides opportunities for boating, fishing, swimming,
camping, and hiking (http://www2.thingstodo.com/statesAVA/nationalparks/lakeroosevelt.htm).
Surface water intakes are reported to lie within the surface water target distance limit (TDL) for
each of the mines/mills sampled. The average number of persons per household in Stevens County is
2.64 (USBC 2000); therefore, the START-2 estimates the following:
There are 5.28 persons using surface water from Magee Creek for drinking water within
the 15-mile TDL of Daisy Mine;

Lake Roosevelt and its tributaries in the Lake Roosevelt National Recreation Area support a
varied fish community that today is considerably different from the native fish community of the early
1900s. The changes over time were caused by the introduction of nonnative species, habitat alterations
such as water pollution, the damming of rivers, and reservoir drawdowns. Today, there are possibly
28 native and 12 nonnative species of fish that inhabit recreation area waters. (DOI 2000)
Between 1990 and 1996 the number of angler trips to Lake Roosevelt ranged from 171,725 to
594,508 per year. Recreational fishing trips to Lake Roosevelt peaked in 1993 and have been declining
since. The decline was partly attributed to the dewatering of boat ramps during the 1996 drawdown that
prohibited anglers from accessing much of the reservoir. Walleye, rainbow trout, and kokanee salmon
were the fish most often caught and harvested by anglers. (DOI 2000) Data provided by the Lake
Roosevelt Fisheries Evaluation Project; a cooperative project amongst the Spokane Tribe of Indians, the
Colville Confederated Tribes, and the Washington Department of Fish and Wildlife; to the EPA indicates
that over a ten week period from July 13, 2002 to September 20, 2002, 576 fish were caught by anglers
from Lake Roosevelt. These fish consisted of 338 walleye, 221 rainbowtrout, and 17 kokanee salmon.
(Lee 2002) The State of Washington only tracks sturgeon, salmon, and steelhead in its freshwater sport
fishing data. They list that 4 sturgeon were harvested between Grand Coulee Dam and the Canadian
border in 1998. No steelhead and salmon are reported (WSDFW 2001).
The Spokane Tribe and the Colville Confederated Tribes, and the Washington Department of
Fish and Wildlife are the primary agencies directly involved in managing the Lake Roosevelt fisheries.
The Spokane Tribe is coordinating the development of a Lake Roosevelt fisheries plan, funded by the
Bonneville Power Administration in cooperation with the Washington Department of Fish and Wildlife,
the Colville Confederated Tribes, and other involved parties. Two kokanee salmon hatcheries are
operated by the Spokane Tribe and the Washington Department of Fish and Wildlife to support the
resident fishery in Lake Roosevelt. The hatcheries produce thousands of kokanee for release into Lake
Roosevelt annually. The Spokane Tribe also has initiated a program of rearing rainbowtrout at its
hatchery for release into the lake. (DOI 2000)
In addition to the hatchery operations, there are numerous rainbowtrout pens on Lake Roosevelt.
These fish-rearing pens provide thousands of trout annually to support the recreational fishery. The
success of this project in providing catchable-size rainbowtrout resulted in its expansion to more than
10:START-2\01020028\S759

-------
30 net pens in several locations on Lake Roosevelt by 1995. In addition, some of the net pens are now
being used to rear kokanee before release. (DOI 2000)
The Lake Roosevelt National Recreation Area is present along the Columbia River from Grand
Coulee Dam to nearly the U.S.-Canada border. Six species may inhabit areas in or near the Lake
Roosevelt National Recreation Area that are protected by the Endangered Species Act. Of these, gray
wolves (Canus lupus), peregrine falcons (Falco peregrinus), and woodland caribou (Rangifer tarandus
caribou) were endangered, and the bald eagle (Haliaeetus leucocephalus), bull trout {Salvelinns
confluentus), and grizzly bear (Ursus arctos horribilis) were threatened. The Canada lynx (Felis lynx
canadensis), a proposed species for listing, may also inhabit lands in or near the Lake Roosevelt National
Recreation Area. The Canada lynx is not currently protected under the Endangered Species Act. The
state of Washington also listed gray wolves, peregrine falcons, woodland caribou, and grizzly bears as
endangered and the bald eagle and Canada lynx as threatened. (DOI 2000)
Peregrine nests have been found in the area surrounding the Lake Roosevelt reservoir. Use of the
area by peregrines normally occurs during spring and fall migrations. Peregrine falcon foraging and
nesting habitats are usually associated with tall cliffs near water. Their diet consists primarily of
waterfowl, shorebirds, and passerine species commonly found on and around lakes and streams.
(DOI 2000)
No confirmed gray wolf sightings have been documented in the Lake Roosevelt National
Recreation Area; however, numerous unconfirmed sightings have been reported in some surrounding
areas in recent years. (DOI 2000)
Between 1987 and 1990, 60 woodland caribou were moved to northern Idaho from British
Columbia to help bolster the existing remnant herd. The herd has been augmented as recently as 1998.
However, it is unlikely that woodland caribou would be found in the immediate vicinity of the Lake
Roosevelt National Recreation Area. Woodland caribou are known to occur in northeastern Washington;
however, none have been reported in the national recreation area. Most caribou remain in forested
habitats year-round. (DOI 2000)
Bald eagles maintain a large overwintering population in the area surrounding the Lake
Roosevelt reservoir from November through March annually. More than 21 bald eagle nests are in the
vicinity and bald eagles appear to be becoming more productive each year. A maximum of 15 territories
has been occupied in any one year. Bald eagle habitat is usually associated with large bodies of water
that provide an abundant source of food. (DOI 2000) Bald eagle habitat has been observed on the
Columbia River/Lake Roosevelt within the 15-mile TDLs of Napoleon Mine/Mill, Van Stone Mine/Mill,

Although grizzly bears occur in the Selkirk ecosystem in northern Idaho and Washington,
population levels are believed to be low. No grizzly bears have been recently reported within the
National Recreation Area. (DOI 2000)
Bull trout historically occupied a vast geographic area of the Columbia River. T oday the
remaining populations are isolated and remnant. Native bull trout have declined significantly in the last
10 years, in part due to predation by and competition with introduced species such as walleye. If bull
trout are present, Lake Roosevelt and its tributaries could provide suitable habitat. Bull trout typically
migrate from lakes in the fall to spawn in clear streams with flat gradient, uniform flow, and uniform
gravel or small cobble. (DOI 2000)
Lynx have been seen near the northern end of Lake Roosevelt; however, no evidence of resident
populations have been documented. Lynx prefer the density of coniferous forests and swamp areas
where their coloring allows them to be camouflaged from their prey. (DOI 2000)
In addition to the aforementioned, another 24 animal species of concern to the state of
Washington or the United States Fish and Wildlife Service may occur in or near the Lake Roosevelt
National Recreation Area. These include the threatened ferruginous hawk (Buteo regalis); the candidates
California floater (Anodonta californiensis), Columbia sharp-tail grouse (Tympanuchusphasianellus
Columbians), Columbia spotted frog (Rana luteiventris), loggerhead shrike (Lanius ludovicianus),
northern goshawk (Accipiter gentilis), Pacific fisher (Martes pennanti pacifica). pale Townsend's
big-eared bat (Corynorhinus townsendii pallexcens), and Washington ground squirrel (Spermophilus
Washington!). (DOI 2000)
No federally-listed, proposed, or candidate plants are known to occur within the Lake Roosevelt
National Recreation Area. (DOI 2000)
Lake Roosevelt is the largest single geographic feature in the northeastern corner of Washington
state. The surrounding countryside is mostly rural except for the small towns in the Kettle Falls and
Grand Coulee Dam areas. There are five counties and two Indian reservations that touch upon Lake
Roosevelt National Recreation Area. Grain, forestry, lumber, and mining are the principal economic
activities of the region. (DOI 2000)
North and west of the lake, the country is relatively mountainous and largely forested with a
small amount of farmland. Logging and mining dominate the economy. East of the lake, the country is
more mountainous than rolling and is a mixture of forest and farmland. Forest products manufacturing

dominates the economy. South of the Lake, the topography is generally flatland with low rolling hills.
Agriculture is the backbone of the economy, with wheat as the primary crop. Recreational activities,
largely fishing, supplement the economy and are potentially significant. (DOI 2000)
Lake Roosevelt is one of the major focal points of recreation in a region that boasts an abundance
of recreational opportunities. Within a radius of approximately 100 miles from Grand Coulee Dam, there
are four national forests, six other major lakes or reservoirs, several smaller reservoirs on the Columbia
and Snake rivers, North Cascades National Park, and Lake Chelan National Recreation Area. The
national forests have a substantial complementary recreation potential, which consists of smaller lake and
stream fishing, camping, hunting, and winter sports. The Grand Coulee Dam itself is a tourist destination
that attracts more than 400,000 visitors a year to tour the dam and watch the laser light show.

8. SUMMARY AND CONCLUSIONS
In June and September 2001, the ST ART -2 conducted P As and Sis of mines/mills located near
the upper Columbia River in Stevens County, Washington.
The purpose of the PAs and Sis were to identify and investigate potential sources of
contamination to the upper Columbia River. Of the 39 mines/mills visited, sampling was conducted at
18 properties. Sampling was conducted at those mines/mills where potential sources of contamination
were identified and potential impacts to receptors via the surface water migration pathway were
observed.
The PAs and Sis activities involved the collection of samples from potential hazardous substance
source areas and from target areas/receptors potentially impacted by contaminant migration. A total of
216 samples submitted for EPA CLP methods of analysis were collected, including background samples
but excluding QA samples. The media sampled included surface soil, tailings, waste rock, surface water
and sediment. Section 8.1 summarizes the findings and conclusions for those mines/mills that were
sampled. This section does not include a discussion for sites that were not sampled. Sampling was not
conducted at sites where no contaminant source was observed and/or where no surface water features
including overland drainage routes were identified. Recommendations for all sites are presented in
Table 8-1.
8.1 FINDINGS AND CONCLUSIONS
8.1.1 Daisy Mine
Samples were collected from potential contaminant source areas at the Daisy Mine including a
tailings pile and shaft. A PPE sample was also collected. The tailings pile measured 150 feet at the base,
30 feet in height with a slope of approximately 35%, and a depth of approximately 45 feet. The shaft
measured 10 feet by 10 feet by unknown depth. A wet area originating from the shaft extended south
approximately 25 feet. A depression south of the wet area was noted where potential pooling of water
from the shaft would occur which would then flow into the ditch, past the culvert, and into Magee Creek
approximately 70 feet (PPE 1).
10:START-2\01020028\S759
8-1
-------
Surface soil samples collected from the tailings pile contained significant concentrations of TAL
metals including arsenic (233 mg/kg) and mercury (2.9 mg/kg).
Analytes detected in the discharge from the shaft include arsenic (95.3 /ig/L). cadmium
(7.1 (A.g/L), lead (5.2 (A.g/L), and zinc (829 (Ag/L).
No elevated concentrations of TAL metals were detected in the PPE sample.
Based on an evaluation of technical data using the EPA HRS model criteria, no further action
under CERCLA is recommended at the Daisy Mine site.
8.1.2 L-Bar/Northwest Magnesite
The contaminant sources at L-Bar/Northwest Magnesite includes a magnesite pile, and flux bar
and flux bar residue. The magnesite residue pile measures approximately 30 feet deep and 17 acres in
area. Past operating practices and inadequate storage of flux bar and flux bar residue have resulted in
elevated levels of mostly chloride and ammonia in shallow groundwater and surface water. Most of the
materials remaining on the plant have continued to leach salts and ammonia into shallow groundwater
and surface water in two ditches. (Ecology 2001)
Sediment samples were collected during the Phase I RI from six locations: three in the Main
Ditch, two in the West Ditch, and one from the Logan Road ditch south of the property. Review of trace
metals analyses shows that barium, manganese, and selenium concentrations in the Main Ditch sediment
samples exceeded the concentrations detected in the background sample collected from Logan Road
ditch south of the property. Trace metals results from the West Ditch samples were similar to Main
Ditch samples in that background concentrations were exceeded for arsenic, barium, copper, manganese,
and selenium. Concentrations of these metals were less than 2 times background levels except for
selenium, which was approximately 7 times background. (CH2MHill 1998)
Sediment samples were collected at two PPEs by the START-2 in the West Ditch. One
downstream sediment sample was also collected from the West Ditch and one sediment sample was
collected from the Colville River.
Samples collected from the West Ditch contained elevated concentrations of TAL metals
including selenium (18.0 mg/kg JK).
Lead was detected at an elevated concentration in the Colville River sample; however, this
analyte was not similarly detected in PPE samples.
Based on an evaluation of technical data using the EPA HRS model criteria, further action under
CERCLA or other authorities is recommended at the L-Bar/Northwest Magnesite site. A Cleanup Action
10:START-2\01020028\S759
8-2
-------
Plan for the site was approved by Ecology in June 2000 requiring source removal, monitoring, and
institutional controls.
8.1.3 Northwest Alloys
The plant is contained within gates and hillsides. There is no overland flow from the site directly
into the Colville River due to topography. A potential overland flow exists on the western portion of the
plant. The overland flow potentially flows through ditches (PPE 1) south towards Stensgar Creek.
Stensgar Creek, located south of the plant, maintains brown trout. Stensgar Creek feeds into the Colville
River. One PPE sample and two target/receptor samples were collected.
Samples collected in the ditch at PPE 1 contained elevated concentrations of arsenic (4.9 mg/kg),
copper (18.7 mg/kg), lead (7.5 mg/kg), and zinc (47.9 mg/kg). No elevated concentrations of TAL metals
were detected in target/receptor samples.
Based on an evaluation of technical data using the EPA HRS model criteria, no further action
under CERCLA is recommended at the Northwest Alloys site. However, voluntary cleanup actions
currently are being carried out at the site under the Model Toxics Cleanup Authority, Voluntary Cleanup
Program administered by Ecology's Industrial Section.
8.1.4 Napoleon Mine/Mill
The mine/mill area consisted of an adit measuring 5 feet by 4 feet located south of the dirt road
entrance. There was no evidence of tailings or waste rock present on the property. The adit discharge
flowed across the dirt road, down the hillside approximately 120 feet before entering an intermittent
creek (PPE 1). Iron staining was present on the soil and the dirt road. There was no adit discharge at the
time of the visit. One surface water sample from the adit was collected. One PPE sample was also
collected.
Analytes detected in the discharge from the adit include lead (11.3 /ig/L), and zinc (937 /ig/L).
Significant levels of TAL metals were detected in the PPE sample including copper (207 mg/kg)
and silver (2.3 mg/kg).
Analytical results of samples collected indicate that hazardous substances are migrating to
targets/receptors.
Based on an evaluation of technical data using the EPA HRS model criteria, no further action
under CERCLA is recommended at the Napoleon Mine/Mill site.
10:START-2\01020028\S759
8-3
-------
8.1.5 Van Stone Mine/Mill
Samples were collected from potential contaminant source areas at the Van Stone Mine/Mill
including a waste rock pile, two tailings piles, 7 stained soil areas, and mine pit water. Four PPE samples
were also collected.
Surface soil samples collected from source areas contained significant concentrations of TAL
metals including cadmium (940 mg/kg), lead (181,000 mg/kg), mercury (6.0 mg/kg), and zinc
(431,000 mg/kg).
The PPE samples contained elevated concentrations of TAL metals including cadmium
(11.9 mg/kg) and zinc (3,670 mg/kg).
In the past, the mine, slurry flume, and tailings piles were likely a source of sediment to streams
in the Onion Creek watershed. Based on aerial photo evidence and anecdotal reports from area residents,
the slurry flume periodically broke, and the tailings slurry was dumped into the stream north of the old
tailings pile for hours at a time before the break was discovered and repaired. In addition, it is reported
that the old tailings pile wall was breached at least once in the past, transporting tailings material into the
stream. (Boise Cascade Corporation 1997)
The newtailings pile is not reported to have had any major erosion occurrences; however, there
is a layer of tailings material several feet thick covering the stream valley north of the newtailings pile
(Boise Cascade Corporation 1997).
At present, the steep outer walls of the tailings piles are subject to surface erosion, as evidenced
by the rills and gullies developed on the walls. A small berm has been made around the tailings piles to
contain eroded material and is effective in containing eroded material. The owner is testing erosion
control methods on the tailings pile walls. (Boise Cascade Corporation 1997)
Analytical results of samples collected indicate that hazardous substances are migrating to
targets/receptors.
Based on an evaluation of technical data using the EPA HRS model criteria, further action under
CERCLA or other authorities is recommended at the Van Stone Mine/Mill site.
8.1.6 LeRoi/Northport Smelter
Samples were collected from potential contaminant source areas at the LeRoi/Northport Smelter
including surface soil west of the former tailings area underneath slag bricks, sediment from slag areas
along the Columbia River adjacent to the smelter (PPE 3), and sediment in the western portion of the
recently constructed ditch where the former tailings pile was located (PPE 1 and PPE 2).
10:START-2\01020028\S759
8-4
-------
Surface soil samples from source areas contained significant concentrations of TAL metals
including arsenic (297 mg/kg JL), cadmium (105 mg/kg), lead (10,500 mg/kg), mercury (0.40 mg/kg),
and zinc (5,420 mg/kg).
Sediment samples collected from the Columbia River contained elevated concentrations of T AL
metals including arsenic (41.4 mg/kg), cadmium (4.9 mg/kg), copper (2,960 mg/kg), lead (845 mg/kg
JK), mercury (0.29 mg/kg), and zinc (16,900 mg/kg).
The ditch PPE samples contained elevated concentrations of TAL metals including arsenic
(39.9 mg/kg JK), cadmium (5.9 mg/kg JK), copper (1,090 mg/kg), lead (887 mg/kg JK), and zinc
(223 mg/kg).
Analytical results of samples collected indicate that hazardous substances are migrating to
targets/receptors.
Based on an evaluation of technical data using the EPA HRS model criteria, further action under
CERCLA or other authorities is recommended at the LeRoi/Northport Smelter site.
