How to Use the NPL Book
pO
The site fact sheets presented in this book
are comprehensive summaries that cover a
broad range of information. The fact sheets
describe hazardous waste sites on the NPL and
their locations, as well as the conditions
leading to their listing ("Site Description").
The summaries list the types of contaminants
that have been discovered and related threats
to public and ecological health ("Threats and
Contaminants"). "Cleanup Approach" pres-
ents an overview of the cleanup activities
completed, underway, or planned. The fact
sheets conclude with a brief synopsis of how
much progress has been made in protecting
public health and the environment. The
summaries also pinpoint other actions, such as
legal efforts to involve polluters responsible
for site contamination and community con-
cerns.
The fact sheets are arranged in alphabetical
order by site name. Because site cleanup is a
dynamic and gradual process, all site informa-
tion is accurate as of the date shown on the
bottom of each page. Progress is always being
made at NPL sites, and the EPA periodically
will update the site fact sheets to reflect recent
actions. The following two pages show a
generic fact sheet and briefly describe the
information under each section.
How Can You Use
This State Book?
You can use this book to keep informed
about the sites that concern you, particu-
larly ones close to home. The EPA is commit-
ted to involving the public in the decision
making process associated with hazardous
waste cleanup. The Agency solicits input from
area residents in communities affected by
Superfund sites. Citizens are likely to be
affected not only by hazardous site conditions,
but also by the remedies that combat them.
Site cleanups take many forms and can affect
communities in different ways. Local traffic
may be rerouted, residents may be relocated,
temporary water supplies may be necessary.
Definitive information on a site can help
citizens sift through alternatives and make
decisions. To make good choices, you must
know what the threats are and how the EPA
intends to clean up the site. You must under-
stand the cleanup alternatives being proposed
for site cleanup and how residents may be
affected by each one. You also need to have
some idea of how your community intends to
use the site in the future, and you need to know
what the community can realistically expect
once the cleanup is complete.
The EPA wants to develop cleanup methods
that meet community needs, but the Agency
only can take local concerns into account if it
understands what they are. Information must
travel both ways in order for cleanups to be
effective and satisfactory. Please take this
opportunity to learn more, become involved,
and assure that hazardous waste cleanup at
"your" site considers your community's
concerns.

SITE DESCRIPTION
This section describes the location and history of the site. It includes descrip-
tions of the most recent activities and past actions at the site that have con-
tributed to the contamination. Population estimates, land usages, and nearby
resources give readers background on the local setting surrounding the site.
THREATS AND CONTAMINANTS
The major chemical categories of site contamination are noted, as well as
which environmental resources are affected. Icons representing each of the
affected resources (may include air, groundwater, surface water, soil, and
contamination to environmentally sensitive areas) are included in the margins
of this section. Potential threats to residents and the surrounding environ-
ments arising from the site contamination also are described.
CLEANUP APPROACH
This section contains a brief overview of how the site is being cleaned up.
RESPONSE ACTION STATUS
Specific actions that have been accomplished or will be undertaken to clean
up the site are described here. Cleanup activities at NPL sites are divided
into separate phases, depending on the complexity and required actions at the
site. Two major types of cleanup activities often are described: initial,
immediate, or emergency actions to quickly remove or reduce imminent
threats to the community and surrounding areas; and long-term remedial
phases directed at final cleanup at the site. Each stage of the cleanup strategy
is presented in this section of the summary. Icons representing the stage of
the cleanup process (initial actions, site investigations, EPA selection of the
cleanup remedy, engineering design phase, cleanup activities underway, and
completed cleanup) are located in the margin next to each activity descrip-
tion.
SITE FACTS
Additional information on activities and events at the site are included in this
section. Often details on legal or administrative actions taken by the EPA to
achieve site cleanup or other facts pertaining to community involvement with
the site cleanup process are reported here.

EPA REGION 10
Multnomah County
Portland
Site Description
Allied Plating, Inc., occupying 11/2 acres, began operating a chrome-plating facility in Portland
in 1957. The operation generated electroplating wastes containing heavy metals and arsenic. For
over 25 years, the company discharged waste without pre-treatment. Prior to 1969, wastes were
discharged onto a low-lying area of the property, which drained into the Columbia Slough. After
1969, filling activities isolated the site and created a surface impoundment. In mid-1985, during
an EPA inspection, the banks of the pond were found to be eroding, and the natural drainage
channels were filled with refuse. Shortly thereafter, the owner pumped the contents of the pond
into the Portland sewer system. In 1978, the company detected metals in an on-site well and in
industrial and municipal wells within 2 miles of the site. Approximately 20,000 people live within
3 miles of the site. Public and private wells within 3 miles of the site provide drinking water for
about 1,500 people. Water from a well located 1,700 feet from the site is used in food
processing. Groundwater also is used for irrigation. An apartment building and mobile home park
are located nearby, but use city water. The Columbia Slough, which drains into the Willamette
River, is about 600 feet northeast of the site.
Site Responsibility:
The site was addressed through Federal
action.

Deleted Date: 11/14/94
Threats and Contaminants
Groundwater, surface water, sediments, and soil were contaminated with heavy metals,
including chromium and lead. Soil also contained cyanide. Chromium, copper, and
nickel were present in sludge on the site. Contaminated groundwater, soil, and sludge
could have been a potential hazard through direct contact or accidental ingestion.
Drainage from the site could have potentially contaminated the Columbia Slough.
February 1995
-------
Cleanup Approach
Response Action Status
Early Action: The EPA completed an investigation of the site in 1992 to determine
the nature and extent of the contamination and performed an early action at the site.
During this action, the EPA excavated the contaminated soil, surface water, and
sediments and disposed of them off site.
Entire Site: The excavation performed as an early action was successful, and since
the ground water is not a source of drinking water, the EPA determined that no further
action was required at the site to protect public health and the environment. However,
to ensure that groundwater is not used in the future, the EPA imposed a deed restriction on the
property.
Environmental Progress
The excavation and disposal of the contaminated soil, surface water and sediments has eliminated
the former threat to human health and the surrounding habitats. The site was deleted from the
NPL in November 1994.

Portland
Site Description
The East Multnomah County Groundwater Contamination site is approximately 3 square miles in
size and is located east of Portland, Oregon. In 1986, Boeing closed a surface impoundment at
its Portland facility that had been permitted to operate in compliance with the Resource
Conservation and Recovery Act (RCRA). At that time, volatile organic compounds (VOCs) were
found in groundwater. A subsequent investigation by Boeing revealed groundwater
contamination upgradient of the plant. Between 1987 and 1991, the EPA inventoried local
businesses, many of which used VOCs and solvents, and investigated the area extensively,
including sampling wells and conducting an area-wide soil gas survey. The EPA has documented
that the Boeing Co. Portland Plant, Cascade Corp., and Swift Adhesives, a division of Reichhold
Chemicals, Inc., are three of the sources of the groundwater contamination. In addition, a
number of other local businesses may have contributed to the contaminated groundwater plumes
in this area. The businesses that were identified as the potential sources of the contamination
include the local facilities owned by Norwest Paper, Firestone, Opticraft, Northwest Retreader,
and Parker & Grantz Automotive. About 280,000 people, including 267,500 in Portland and the
vicinity, use the affected groundwater as standby wells only.
Site Responsibility:
The site is being addressed through
Federal and State actions.
IMPL LISTING HISTORY
Proposed Date: 05/10/93
Threats and Contaminants
Groundwater is contaminated with VOCs, including trichloroethene (TCE) and two of
its related byproducts, 1-1-dichloroethene and 1,1-dichloroethane. TCE was commonly
used by local businesses as an industrial solvent. Soils near the Cascade Corp. and
Swift Adhesives facilities are contaminated with VOCs. People who touch or ingest
contaminated groundwater or soil may be at risk.
January 1 995
-------
Cleanup Approach
This site is being addressed through early actions and a long-term cleanup phase focusing on the
entire site.
Response Action Status
Early Actions: The Boeing Company and Cascade Corporation have installed two
groundwater extraction wells in the Troatdale Sandstone Aquifer (TSA), which will
serve to protect Portland's production wells in the nearby Blue Lake Aquifer (BLA).
Well pump tests to determine a groundwater extraction program will follow shortly.
Entire Site: An investigation into the nature and extent of contamination at the site is
being conducted by potentially responsible parties under the State's supervision.
Upon completion of this study, the State of Oregon will select a long-term cleanup
approach to address contamination at the site.
Site Facts: EPA and the Oregon Department of Environmental Quality have signed a
memorandum of agreement, which designates the State as the lead agency for cleanup work at
this site. Either independently or under State enforcement orders, several of the parties who are
potentially responsible for the contamination are conducting site studies. Because the Boeing
plant is regulated under RCRA, this facility is not part of this NPL site; however, the cleanup of
the Boeing plant will be coordinated with any Superfund actions that take place.
Environmental Progress
The potentially responsible parties have taken measures to protect the City of Portland's drinking
water supply while site studies for final cleanup of the site are underway.

EPA REGION 10
Lake County
1 8 miles Northwest of Lakeview
Site Description
The White King Mine is located in the mountains approximately 18 miles northwest of Lakeview
within the Lakeview Ranger District, Fremont National Forest, Lake County, Oregon. The mine
sits near the west edge of an upland meadow at an elevation of approximately 6,000 feet, and is
situated on both National Forest Land and private land. The Lucky Lass Mine is situated 1 mile
northwest of the White King Mine at an elevation of 6,150 feet and is also on National Forest
land. From the early 1940s through the 1960s, uranium ore was mined for use in natural defense
research, weapons development, and the commercial nuclear energy industry. The Atomic
Energy Commission oversaw ore production from the mines. A total of 140 acres were disturbed
by mining activities. Three types of wastes were left behind at the mine sites: stockpiled ore,
rock, and soil (known as "overburden") mixed with ore, and ore and acid wastewater that has
filled the open pit mines. The uranium ore and overburden contain elevated levels of naturally
occurring radioactive materials and other hazardous substances. The stockpiles remain
unprotected and exposed to the elements. Contaminant areas included stockpiled ore, overburden
mixed with ore, and acid drainage waste water that has filled the pits created by the mining
activities. Auger Creek flows nearby the site, supporting wetlands and recreational fishing.
Site Responsibility:
The site is being addressed through
Federal and State actions.
NPL LISTING HISTORY
Proposed Date: 06/23/93
Threats and Contaminants
Surface water and sediments in Auger Creek and nearby wetlands have been
contaminated by mining activities. The primary hazards posed by the mine waste
include gamma radiation exposure from radioactive constituents, emanation of radon
gas, and the contamination of surface and groundwater by heavy metals and
radioactive constituents. The creek and surface water bodies downstream of the site
are used as a source of recreational fishing. Touching or ingesting contaminated
surface water, sediments, or groundwater could pose a health risk.
January 1995
-------
Cleanup Approach
The site is being addressed in three stages: the cleanup of Lucky Lass mine; the overburden,
tailings, and ponded water at White King mine; and surface and groundwater contamination at
White King mine.
Response Action Status
Lucky Lass Mine: Options are being evaluated for draining the pond, backfilling it
with clean material, and removing contaminated soils as an interim cleanup action.
These actions are expected to occur in 1995.
Overburden, Tailings, and Ponded Water: Options are being evaluated for
treating and draining the ponded water, backfilling it with clean material, and placing
contaminated overburden tailings and sediment in a waste encapsulation cell as an
interim cleanup action. These actions are expected to occur in 1995.
Surface and Groundwater: An investigation into the nature and extent of surface
and groundwater contamination is planned at the site. Following the investigation,
final cleanup measures will be selected.
Environmental Progress
EPA has determined that this site poses no immediate threat to human health and the
environment. The U.S. Forest Service, EPA, and the State of Oregon are evaluating the
feasibility of conducting interim cleanup actions in 1995 at the Lucky Lass mine and addressing
overburden, tailings, and ponded water.

Site Description
The Gould, Inc. site covers about 10 acres in an industrial area in northwestern Portland known
as the Doane Lake area. From 1949 until 1981, various site owners operated a secondary lead
smelting facility specializing in lead-acid battery recycling, lead smelting and refining, zinc
alloying and casting, cable sweating, and lead oxide production. During the facility operations,
recycled batteries were disassembled, fragmented, and disposed of in adjacent Doane Lake or
next to the recycling facility. About 87,000 tons of battery casings were disposed of at the site,
and about 6 million gallons of acid were discharged into the lake. Operations ceased in 1981 and
by mid-1982, most of the structures, facilities, and equipment were removed. However, surface
piles of approximately 2,000 tons of battery casings remain on the site. A few private residences
and rental units are located to the south and west of the facility. Approximately 270 people are
employed by the businesses in the vicinity and on the site. About 10,000 people live within a
mile of the site. The facility is located within the flood plain of the Willamette River.
Site Responsibility:
The site is being addressed through a
combination of Federal, State, and
potentially responsible parties' actions.
NPL LISTING HISTORY
Proposed Date: 12/30/82
Final Date: 09/08/83
Threats and Contaminants
Lead and volatile organic compounds (VOCs) have been detected in on-site
groundwater. Lead, chromium, and arsenic are present in the sediments of Doane
Lake. Soil contains arsenic, lead, and cadmium. Potential health risks may exist for
individuals who accidentally ingest contaminated soil, sediments, surface water, or
groundwater. Access to the site is restricted, thereby reducing the potential for people
to come into direct contact with contamination.
Cleanup Approach
The site is being addressed in two long-term remedial phases focusing on cleanup of soils and
sediments, and groundwater and surface water.
January 1995
-------
Response Action Status
Soils and Sediments: In 1993, the responsible parties began excavating and
treating contaminated surface soils, battery casings, smelter waste, and other debris.
Excavated battery casings have been treated to separate materials for recycling,
thereby minimizing the amount of material to be landfilled. Work on the battery recycling
process has been temporarily suspended. The responsible parties are conducting a study to
further evaluate the cleanup methods to treat the soil. After soil is treated, the stabilized soil will
be placed back in the ground and capped with clean soil. Water runoff will be isolated and
groundwater will be monitored. Cleanup work is expected to be completed in 1996.
Groundwater and Surface Water: The Doane Lake Industrial Group, under State
supervision, conducted hydrogeological studies to determine if additional groundwater
and surface water cleanup activities are needed. A draft report was submitted to the
State in 1991. Based on this preliminary study, a complete investigation to determine the full
extent of contamination and to study alternative cleanup technologies is now being performed by
Rhone-Poulene, a company which is part of the Doane Lake Industrial Group. This investigation
is scheduled for completion in mid-1996.
Site Facts: In April 1989, a Consent Decree between a potentially responsible party, NL
Industries, and the EPA was lodged with the Federal District Court in Portland. NL Industries
agreed to conduct treatability studies needed to carry out the selected remedy. Following EPA
approval of a pre-design report in March 1991, NL Industries signed a Consent Order with EPA
to complete the engineering designs of the soil cleanup. The EPA issued Unilateral
Administrative Orders to seven potentially responsible parties in January 1992 requiring them to
assist in performing and funding cleanup at the site. The EPA and the Department of Justice
reached an agreement with six companies who contributed relatively small amounts of waste to
the site. The parties agreed to pay for a portion of EPA's past and future costs at the site.
Environmental Progress
After adding this site to the NPL, the EPA conducted preliminary investigations and determined
that no immediate actions were needed while final cleanup activities proceed at the Gould, Inc.
site.

EPA ID# ORD068782820
EPA REGION 10
Wallowa County
1 mile northwest of
the Town of Joseph
Site Description
Joseph Forest Products formerly treated wood on an 18Vi-acre site located approximately one
mile northwest of the Town of Joseph. The wood treatment process used a water-based mixture
of chromated copper arsenate (CCA). After the treatment cycle was completed, the treatment
solution was pumped into a storage tank for reuse. The portion of the solution that could not be
pumped was drained into a 2,042-gallon cement sump and later transferred to the storage tank.
Wood waste, sludges, and other process wastes were stored in a cement pit. A fire in 1974
destroyed the treatment building and resulted in a spill of concentrated preservative mixture onto
the ground. Treatment operations did not resume at the site until the latter part of 1977. In 1985,
the EPA detected elevated levels of contaminants in soils at the site. The wood treating operation
was closed in 1985. Currently, wood cutting and planing are the only activities at the site. The
shallow groundwater aquifer lies 5 to 10 feet below the surface and is overlain by very permeable
soils, conditions that facilitate movement of contaminants into groundwater. Approximately 1,000
people live within 3 miles of the site. Groundwater within 3 miles of the site provides drinking
water to more than 2,000 people. The site lies within the City of Enterprise Watershed Protection
Area. The City of Enterprise obtains drinking water from springs 4,000 feet from the site.
Groundwater also is used for irrigation. The Wallowa River is located 400 feet east of the site
and is used for recreational purposes.
Site Responsibility:
The site was addressed through Federal
actions.
NPL LISTING HISTORY
Proposed Date: 06/24/88
Final Date: 03/31/89
Threats and Contaminants
Elevated levels of arsenic, chromium, and lead existed in on-site groundwater,
sediment, and soil. Arsenic and chromium also were detected in standing water from
the cement pit. Individuals who accidentally ingested groundwater, soil, sediments, or
surface water were at risk. Inhalation of windblown contaminated dust particles also
posed a health threat. The Wallowa River and Hurricane Creek were threatened by the
site contaminants.
January 1995
-------
Cleanup Approach
Response Action Status
Early Actions: In late 1991, the EPA removed highly contaminated soils adjacent
to the treatment building and dip pad. Approximately 1,000 tons of contaminated
soils were excavated and transported to a hazardous waste disposal facility. A
security fence was also installed around the treatment building to control access.
Entire Site: The long-term cleanup was completed in mid-1993. Cleanup crews
removed and decontaminated the process equipment from the wood preservative
treatment building, demolished the building, excavated the contaminated soil beneath
the building, removed additional contaminated soil from the site, disposed of hazardous wastes at
an approved hazardous waste facility, removed two underground petroleum tanks, disposed of
soil contaminated with petroleum products at an off-site facility, removed materials containing
asbestos, coated the interior surfaces with a sealant to encapsulate any remaining fibers in
accordance with state requirements, and conducted extensive soil sampling and analysis to
confirm that the established cleanup levels were achieved. Cleanup activities are complete.
Ground water monitoring will continue for two years to ensure the protectiveness of the remedy.
Site Facts: This site was addressed through EPA's Superfund Accelerated Cleanup Model
(SACM) initiative. The intent if this initiative is to speed up the process by which the nation's
worst hazardous waste sites are cleaned up. Under SACM, site assessment activities are
undertaken to support both early and long-term cleanup actions. Site conditions and their
associated risks are assessed continuously until all necessary data are collected to screen the site
or support any needed response actions. Response actions are initiated once evidence indicates
that early action is warranted.
Environmental Progress
Cleanup is complete at the site; the threats to the environment and the public have been
eliminated. The EPA will conduct groundwater monitoring for the next two years to ensure that
the City of Enterprise water supply continues to be protected.

Site Description
REGION
Wasco County
The Dalles
10
The 350-acre Martin-Marietta Aluminum Co. site is located in The Dalles. The site lies within an
800-acre area used primarily for heavy industry and manufacturing; land not used for industrial
processes is leased for agricultural purposes. Martin-Marietta acquired the facility in 1970 from
Harvey Aluminum, Inc. and continued aluminum processing operations until 1984, when the
plant was shut down. In 1986, Martin-Marietta leased the plant and an adjacent portion of the
property to Northwest Aluminum Company, which resumed aluminum operations in 1987. The
site consisted of 28 areas of significant contamination which resulted from treatment, storage, and
disposal practices at the site. A 15-acre landfill, now capped, contains approximately 200,000
cubic yards of waste and construction debris including asbestos, metallic wastes, and 5,000 tons
of spent potliner materials (cathode waste) containing cyanide, poly cyclic aromatic hydrocarbons
(PAHs), and arsenic. Leachate emanating from the landfill prior to the installation of a leachate
collection system resulted in the contamination of the area groundwater. In addition to the
landfill, approximately 64,670 cubic yards of cathode waste material were deposited in the
unloading area and the cathode waste management areas. This area covers 15 acres and contains
contaminated sludge and subsoil. Fewer than 20 homes and businesses are located in the vicinity
of the site. The nearest residence is located approximately 14 mile from the facility. Groundwater
provides drinking water to 14,000 people in The Dalles and Chenoweth. The wells in the
immediate vicinity also are used for industrial purposes.
Site Responsibility:
The site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 10/15/84
Final Date: 06/10/86
Threats and Contaminants
Groundwater on site was contaminated with cyanide. Sediments and soil contained
fluoride, asbestos, PAHs, and arsenic. People who accidentally ingested or came into
direct contact with groundwater, soil, and sediments may have been at risk. Because
the site is located within the Columbia River flood plain, flooding could have
potentially affected groundwater flow patterns and contaminant distribution.
January 1995
-------
Cleanup Approach
Response Action Status
Entire Site: Based on the results of an investigation completed in 1988, the EPA
selected a two-stage cleanup. The first stage of the cleanup, which was completed in
1990 by the potentially responsible parties under EPA monitoring, consisted of:
excavating the cathode waste material and placing it into the existing landfill; installing a soil cap
over scrubber sludge ponds 2 and 3; and groundwater monitoring. The second stage was
completed in 1991 and included: capping the landfill; collecting and treating on-site leachate
generated from the landfill and groundwater east of River Road, as well as groundwater from a
variety of places at the site; plugging and abandoning nearby production wells and connecting
groundwater users to the City of The Dalles water supply system; establishing a contingency plan
to recover groundwater in the event further contamination is detected; and implementing site use
restrictions or fencing following the cleanup. In early 1992, Martin Marietta informed the EPA
of a problem with the leachate collection system around the landfill. Several studies and
construction activities were performed around the landfill in 1992 and 1993. Based upon these
studies, Martin Marietta determined that the source of the additional leachate is water infiltrating
through the fractured bedrock system beneath the landfill. The cap over the landfill is operating
as designed and safety levels have not been exceeded. Martin Marietta upgraded the leachate
treatment system in early 1995 to accommodate additional volumes of leachate over the long-
term. Ongoing groundwater monitoring is scheduled to continue at least through 1995.
Site Facts: In July 1989, Martin-Marietta signed a Consent Decree, agreeing to perform the
cleanup work and to reimburse the EPA for past cleanup costs.
Environmental Progress
All construction at the site has been completed. Excavating the cathode waste material, capping
the sludge ponds, capping the landfill, plugging production wells, and implementing site deed
restrictions have reduced the threat to the public and the environment resulting from
contamination at this site. The upgrade to the leachate treatment system ensures the continued
protectiveness of the remedy.

Site Description
The McCormick & Baxter Creosoting Company site covers approximately 58 acres at 6900
Edgewater Street, approximately 4 miles south of the city of Portland. The site is situated in an
industrial area on the banks of the Willamette River. McCormick & Baxter was founded in 1944
to produce treated wood products during World War II. Wood treating products used at the site
include creosote/diesel oil mixtures, pentachlorophenol (PCP)/diesel oil mixtures, and a variety of
water- and ammonia-based solutions containing arsenic, chromium, copper, and zinc. Between
1945 and 1969, wastewater and non-contact cooling water were discharged directly into the
Willamette River. Prior to 1971, boiler water, storm water, and oily wastes were disposed of in
the western portion of the site. Tanks at the facility held mixtures of creosote, PCP, oil, and oily
wastewater. The facility ceased wood treating operations in 1991. Approximately 12,000 people
live within 3 miles of the site.
Site Responsibility:
The site is being addressed through
Federal and State actions.
NPL LISTING HISTORY
Proposed Date: 06/23/93
Final Date: 05/31/94
Threats and Contaminants
Soils at the site are contaminated with wood treating chemicals, including heavy
metals, poly cyclic aromatic hydrocarbons (PAHs), and PCP reaching depths of 80 feet
in some areas. The soil contaminants have migrated to sediments in the Willamette
River, resulting in the contamination of the river water. Sediments near the site are
contaminated with PAHs to depths of up to 35 feet below the sediment surface.
Touching or ingesting contaminated soils, sediments, or surface water could pose a
health threat. A variety of recreational activities occur in and along the Willamette
River, downstream of the site.
January 1 995
-------
Cleanup Approach
The site is being addressed through early actions focusing on immediate threats and reducing
contaminant migration and a long-term action focusing on cleanup of the entire site.
Response Action Status
Initial Actions: The Oregon Department of Environmental Quality (ODEQ) is
undertaking the following early actions to address site contamination: pumping and
treating creosote from 20 extraction wells; removing sludges from storage tanks,
retorts, and process equipment; removing chemical sludges from surface soils; managing storm
water runoff; and installing interceptor trenches to capture creosote before it reaches the
Willamette River. These actions should be complete by mid-1995. ODEQ and the Oregon
Department of Fish and Wildlife have posted warning signs to alert people to the potential long-
term hazards associated with the site. The site has been fenced to restrict public access.
Entire Site: ODEQ began an investigation in late 1994 to determine the nature and
extent of contamination at the site and to identify options for final cleanup. ODEQ
and EPA are expected to issue a proposed plan for cleanup for public comment in
1995.
Site Facts: McCormick & Baxter filed for Chapter 11 bankruptcy in 1988. In 1989,
responsibility for the site investigation and cleanup was transferred to the ODEQ.
Environmental Progress
ODEQ is conducting early actions at the site to protect against immediate threats to human health
and the environment and to reduce the migration of contaminants from the site prior to long-term
cleanup. Surface soils in off-site residential areas were not found to be affected by contaminants
from the site.

Site Description
The Northwest Pipe & Casing Co. is 53 acres in size and located in an industrial park. The
source of contamination can be traced back to pipe coating operations conducted at the site from
1956 to 1985. This process involved sandblasting the pipes with steel shot, spraying the pipes
with primer, and then coating the pipes. Coal tar, coal tar epoxy, cement mortar, and asphalt all
were used as coatings in this process. Wastes resulting from these plant activities were either
spilled, burned, or buried on site. A pile of waste, the origin of which is unknown, is located in
the northwest part of the site. Six areas of wastes buried on site have been identified and are
thought to be contributing to contamination. On-site surface water drainage from the site flows
into the Willamette River, which is used for fishing. Wetlands and endangered species are found
along this river. Private and municipal wells within 4 miles of the site supply drinking water to
an estimated 6,100 people; the nearest of these wells is within a mile of the site. Approximately
5,200 people reside within a mile of the site.

Troutdale
The Reynolds Metals site is a primary aluminum reduction plant where alumina from bauxite ore
is converted to aluminum. The facility is located approximately 11A miles north of the city of
Troutdale and is bordered by the Columbia River to the north and the Sandy River to the east. A
dike surrounds the plant on the northern and eastern sides, protecting it from floods. Portions of
the site north and east of the dike are within the 100-year flood plain. The United States
government built the plant in 1941 to support its war-time operations. Reynolds first leased the
plant from the government in 1946, and purchased it three years later. Reynolds currently owns
the more than 80-acre plant, as well as approximately 500 surrounding acres. Large quantities of
wastes were generated by the plant during the production of aluminum. In response to a request
for information by the EPA, Reynolds Metals Company (RMC) has identified 21 separate waste
streams. Major hazardous substances of concern include polyaromatic hydrocarbons (PAHs),
aluminum, cyanide, fluoride, and polychlorinated biphenyls (PCBs) from electrical equipment.
The aluminum reduction plant has been out of operation since November 1991 for economic
reasons. Currently, about 100 employees maintain and administer the facility, ensure its security,
and govern the transportation of casting ingots, made from molten aluminum, from the Reynolds
reduction plant in Longview, Washington. The Columbia and Sandy Rivers are used for
recreation and fishing; people reach the rivers by traversing the Reynolds property. Anadromous
fish live in both river.
Site Responsibility:
The site is being addressed through
Federal and potentially responsible

NPL LISTING HISTORY
Proposed Date: 08/23/94
Threats and Contaminants
Samples collected in mid-1993 revealed elevated concentrations of cyanide and fluoride
in several on-site drinking water wells. The EPA also discovered significant levels of
aluminum, barium, manganese, cyanide, and fluoride in surface water samples.
Concentrations of copper and cyanide in an on-site drainage ditch, which flows to an
on-site lake and then to the Columbia River, exceeded the freshwater quality criteria
promulgated under the Clean Water Act. Sediments in the ditch and the lake are
contaminated with fluoride, metals, and PAHs. Wetlands on the site are contaminated
with the same chemicals. Touching or ingesting contaminated groundwater, surface
water, sediments, or soils is a threat to public health.
January 1 995
-------
Cleanup Approach
The approach for investigation and cleanup at the Reynolds Metals site is focused on performing
early cleanup action.
Response Action Status
Entire Site: An integrated assessment of the site was conducted in the summer of
1994. The assessment was designed to identify, characterize, and prioritize all source
and contaminated areas on site. During the eight week assessment, nine areas were
identified that will require cleanup or further investigation. On September 21, 1994, EPA met
with representatives of RMC to discuss progress to date and future action to address imminent
threats identified in three of the nine areas at the facility. The remaining contaminated areas will
be further assessed in a Phase II assessment expected to be initiated later this year.
Site Facts: The EPA is in contact with the Oregon Department of Environmental Quality
(ODEQ) as part of an ongoing effort to identify site stakeholders. The EPA and RMC have
reached preliminary agreement on a schedule for stakeholder involvement in the site decision-
making.
Environmental Progress
Now that contaminated areas have been identified, characterized, and prioritized, imminent
threats will be minimized by performing early cleanup actions at the site.

Site Description
The Teledyne Wah Chang plant in Millersburg is one of the largest producers of zirconium and
other rare earth metals and alloys in the world. The plant's products are principally used in the
nuclear power industry and by the U.S. Department of Defense (DOD). The site includes a 110-
acre plant and a 115-acre area where four ponds which contain sludges from the plant's
wastewater treatment facility are located. Production at the site began in 1957. Process wastes
disposed of on site contained radionuclides, heavy metals, and chlorinated solvents. Solids
generated from the process wastewater treatment system have been stored in a number of surface
impoundments. Until 1980, sludges were taken to seven unlined storage ponds on site, including
the Lower River Solids Pond and Schmidt Lake, both of which are adjacent to the Willamette
River. In 1979, the plant added a process to reduce radiation in sludges and wastewater. On-site
waste storage areas are not fenced. Approximately 20,000 people live within 3 miles of the site.
About 1,100 employees currently work on site; as many as 2,000 people were previously
employed at the plant. The Willamette River and Truax and Murder Creeks border the facility
and are used for recreational activities, irrigation, watering of livestock, and fishing.
Municipalities downstream from the site do not use the Willamette River as a drinking water
source. Private wells within the vicinity of the site are not contaminated.

Threats and Contaminants
On-site sludge was contaminated with thorium, uranium, radium, and heavy metals.
Creek sediments are contaminated with poly chlorinated biphenyls (PCB)s. Shallow
groundwater is contaminated with volatile organic compounds (VOCs), radium, and
heavy metals. Potential health threats include direct contact with and accidental
ingestion of contaminated sludges or groundwater.
January 1995
-------
Cleanup Approach
The site is being addressed in through three long-term cleanup actions focusing on cleanup of the
soil, contaminated sludge, and ground water/sediments.
Response Action Status
Soil: Teledyne Wah Chang, under EPA oversight, is investigating site contamination.
A decision on how to address soils is anticipated in 1995, after a radiological study is
completed.
Sludges: The selected technologies for cleanup of the sludges included removing
approximately 110,000 cubic yards of sludges from the Lower River Solids Pond and
Schmidt Lake; solidifying the sludges, as an interim action, by adding cement to bind
the contaminants and reduce their mobility, making the sludge easier to handle during cleanup;
and removing the mixture to a permitted off-site disposal facility. Cleanup activities were
initiated by Teledyne under EPA oversight in 1991, and were completed in 1993.
Groundwater/Sediments: In the spring of 1994, EPA selected an approach to
clean up contaminated groundwater. Groundwater exceeding a 1/10,000 risk will be
pumped and treated to restore the groundwater to safe levels. In addition, creek
sediments contaminated with PCBs will be removed.
Site Facts: In 1987, Teledyne Wah Chang signed a Consent Agreement with the EPA,
requiring the company to study the nature and extent of site contamination and develop cleanup
alternatives. In 1991, the EPA issued a Unilateral Order to Teledyne for removal of the sludges
from the Lower River Solids Pond and Schmidt Lake.
Environmental Progress
The removal of 110,000 cubic yards of sludge from the site has reduced threats to public health
and the environment while final cleanup actions are being planned.

Site Description
The Umatilla Army Depot (Lagoons) site occupies about 20,000 acres in Hermiston and has
operated as a storage depot for conventional munitions and chemical warfare agents since 1941.
Parts of the depot were contaminated with explosives and metals as a result of past
demilitarization and disposal operations. About 85 million gallons of wastewater from explosive
washout operations were discharged into two unlined lagoons from the 1950s to 1965. The
lagoons cover about 1/2 acre. The ground water contaminant plume is estimated to cover 45
acres. Access to the site is restricted. There are about 100 people living on post, and
approximately 900 people live within 3 miles of the site. The nearest drinking water well is about
6,500 feet from the disposal area. Commercial agriculture is conducted within the vicinity of the
depot, and crops are irrigated with area ground water.

Threats and Contaminants
On-site groundwater and soil are contaminated with explosives including
trinitrotoluene (TNT) and cyclonite (RDX). Soil also contains heavy metals such as
lead and chromium. Potential health threats include accidental ingestion of and direct
contact with contaminated groundwater and soil.
Cleanup Approach
The site is being addressed through seven long-term cleanup actions focusing on the:
Deactivation Furnace; Washout Lagoons Soils (WLS); Active and Inactive Landfills; Washout
Lagoons Groundwater (WLGW); Explosives Washout Plant (EWP); Ammunition Demolition
Activity (ADA); and Miscellaneous Areas.
January 1995
-------
Response Action Status
A site-wide investigation into the nature and extent of contamination at the site was completed in
1992. Remedies, outlining the cleanup plans, were selected for all seven specified areas by the
summer of 1994. Information on each is provided below.
Deactivation Furnace Area: Cleanup and disposal of metal-contaminated soils
from the deactivation furnace area is underway and is expected to be complete in
early 1995.
Washout Lagoons Soils: By the summer of 1994, 6,000 cubic yards of soils
contaminated with explosives were excavated for treatment. EPA contractors are
conducting sampling to evaluate ways to clean up TNT and RDX. Cleanup activities
at this portion of the site are expected to be complete in 1996.
Active and Inactive Landfills: After completing investigations at both the active
and inactive landfills, it was determined that they pose no risks to public health or
the environment. Therefore no further actions will be required.
Washout Lagoons Groundwater: Groundwater cleanup consists of a pump and
treat system that uses granular activated carbon (GAC) to reduce the level of
contamination in a 170-acre plume of ground water mixed with explosive compounds.
The system is being designed to reinject clean groundwater at the site, and is estimated to
continue operating for 10 years. GAC will be treated by off-site thermal regeneration or
incineration. Design of the remedy is expected to be completed in early 1995, with operation of
the system to begin shortly thereafter.
Explosives Washout Plant: The washout plant poses a hazard due to potentially
reactive quantities of explosives that remain in the process equipment and residue of
explosives within the building. Under current conditions, the building is unstable.
The building will be cleaned with solvent wiping and hot gas decontamination. The technical
design of the remedy is expected to be completed in 1995. After cleanup, the building will be
suitable for future use.
Ammunition Demolition Activity Area: Cleanup consists of excavation,
solidification, and on-site landfill disposal of 14,000 tons of soil contaminated with
metals and explosives. In addition, unexploded munitions will be removed from the
site and institutional controls will be implemented to prevent public access to the area. The
technical design for these activities is expected to be complete in 1995.
Miscellaneous Areas: Several other areas remain where soils are contaminated
with metals. Cleanup design work to remove contaminants from these areas is
underway and expected to be complete in mid-1995.
January 1995 2 UMATILLA ARMY DEPOT (LAGOONS)
-------
Site Facts: A three-party Interagency Agreement between the EPA, the Army, and the State of
Oregon was signed in October 1989. The agreement outlined the procedures for the investigation
of the entire facility. Umatilla Army Depot has submitted a Resource Conservation and Recovery
Act (RCRA) permit application to the EPA to construct and operate an incineration facility for
demilitarizing obsolete chemical agents presently stored on site. Umatilla is targeted for closure
under the Base Realignment and Closure Act. This installation is participating in the Installation
Restoration Program, a specially funded program established in 1978 by the Department of
Defense (DOD) to identify, investigate, and control the migration of hazardous contaminants at
military and other DOD facilities.
Environmental Progress
After adding this site to the NPL, the EPA and the Army determined that no immediate actions
were required at the Umatilla Army Depot to protect human health or the environment while final
cleanup actions are being planned. Cleanup activities are ongoing at two areas of contamination at
the site.

Site Description
The IVi-acre United Chrome Products, Inc. site is a former chrome-plating facility located in an
industrial complex adjacent to the Corvallis Municipal Airport, 3V6 miles south of the City of
Corvallis. The company conducted electroplating operations from 1956 to 1985. An on-site dry
well was used to dispose of floor drippings, washings, and product rinsate collected in a sump
within the building. The liquids reportedly were neutralized with sodium hydroxide and/or soda
ash prior to disposal. Major use of the dry well was discontinued in 1975. Although the City of
Corvallis water supply had not been threatened, cleanup was necessary to prevent chromium from
leaving the site or further contaminating the groundwater. Two city wells are located
approximately 3,000 feet northeast of the site; however, the City is not using these wells.
Contamination previously extended over 2 miles off site in surface water, and over IVi miles off
site in sediments. Approximately 42,000 people live within 3 miles of the site. The closest
residence is approximately 900 feet northeast of the facility. Corvallis obtains some of its water

Cleanup Approach -
Response Action Status -
Early Action: In 1985, a total of 8,130 gallons of chromium-contaminated liquids
and 11,000 pounds of hazardous waste solids were shipped off site for recycling or
disposal at approved facilities.
Entire Site: In 1986, EPA documented its final cleanup decision. Since then,
approximately 5,000 people were provided with an alternate water supply, the site
was fenced, and the contaminated debris from the building and the heavily
contaminated soil were disposed of off site. The United Chrome building was demolished in
1988. A groundwater extraction and treatment system began operations to remove chromium
contamination from the groundwater in 1988. Three infiltration basins were installed—two in
1998 and one in 1990. An interim closeout report documenting the completion of construction
activities at the site was signed in late 1991. The extraction and treatment of contaminated
groundwater will continue for several more years until site cleanup goals are met.
Environmental Progress
All construction at the site is complete. The removal of the sources of contamination, the
installation of a groundwater pump and treat system, and the provision of an alternate water
supply have reduced the threats at the United Chrome Products, Inc. site while pumping and
treating of groundwater continues. As of June 1994, over 45,000,000 gallons of contaminated
groundwater had been treated and 31,000 pounds of chromium had been removed.
