The 10-12 square mile Commencement Bay-Nearshore/Tideflats site encompasses shallow
water, shoreline, waterways, and adjacent land in Tacoma, Pierce County, Washington at
the southern end of the main basin of puget Sound. Surrounding land use is primarily
residential and recreational. This site has been divided into eight different operable
units (OUs). Part of this site is on the 67-acre Asarco Tacoma Smelter area, an
inactive copper smelter facility adjacent to puget Sound, which is the focus of this
remedial action. This area consists of over 70 buildings and other structures
including 3 piers, a 562-foot-high stack and a pond used for the discharge of plant
cooling water. From 1890 until 1986, the primary use of the site was for copper
smelting, as well as lead smelting, and sulfuric acid, sulfur dioxide, and arsenic
production activities. Historically, molten slag was used as fill, and was poured onto
the ground at the edge of the shoreline. Subsequently, many of the onsite structures
were constructed over this contaminated material. In 1987, Asarco completed the
initial stabilization of the area which included the demolition of buildings near the
stack. A 1987 ROD addressed OU3-Tacoma Tarpits, an historical coal gasification site.

Commencement Bay-Nearshore/Tideflats (Operable Unit 7-), WA
Third Remedial Action
Abstract (Continued)
A 1989 ROD addressed OU1-CB/NT sediments and OU5-CB/NT sources, both associated with
marine sediments. This ROD provides an interim remedy for OU7, the Asarco Demolition,
and addresses further clearing of the site to prevent the threat of an uncontrolled
collapse of the stack and to minimize contaminant migration to offsite surface water.
The primary contaminants of concern affecting the debris, sludge, and surface water are
metals including arsenic, chromium, and lead; and other inorganics including asbestos.
The selected interim remedial action for this site includes demolishing and dismantling
onsite buildings using conventional techniques after cleaning and/or decontaminating
these structures; removing and disposing asbestos materials offsite; demolishing the
stack by implosion using explosives, with dust suppression using fogging and misting
and/or encapsulation of the stack internal lining; disposing of hazardous, dangerous,
and solid demolition debris offsite and/or temporarily storing debris onsite;
incinerating onsite uncontaminated wood and other combustible materials; cleaning and
decontaminating buildings that will not be demolished; collecting dust suppression
wastewater in the onsite pond, which has been converted to a wastewater evaporation
system; removing a ship to shore oil line, and preventing spillage of any residential
oil; disposing of evaporation pond sludge and dust offsite in a metal recovery facility;
diverting offsite surface water away from the site, and collecting onsite
surface water in the wastewater evaporation system; and monitoring air and surface
water. The estimated present worth cost for this remedial action ranges from
$11,764,500 to $38,686,000. O&M costs were not provided.
PERFORMANCE STANDARDS OR GOALS: Air emissions and dust control must meet the
substantive requirements of the Clean Air Act (CAA) and State regulations. Final
performance standards for ground water and surface water will be determined in the
ROD. Chemical-specific performance standards were not provided.

ACTIVITIES)
Statement of Basis and Purpose
This decision document presents the selected interim
remedial action for demolition activities at the ASARCO
rncorpor~tod (haT~inafLe~ "Asarco" or "Site") site in Tacoma,
Washington devel~ped in ac\~rdance with. the comprehensive
Environmental Response, compensation, and Liability Act (CERCLA)
(42 U.S.C. 9601), as amended by the Superfund Amendments and
Reauthorization Act (SARA), and to the extent practicable, the
National contingency Plan. This action includes demolition of
the majority of structures and buildings at the Site, and other
measures in preparation for the final remedial action at this
Operable Unit 07 of the Commencement Bay Nearshore/Tideflats
Superfund site.
This decision is based on the administrative record for this
site. A copy of the administrative record index is attached as
Appendix VII.
Assessment of the Site
Actual or threatened releases of hazardous substances from
this site, if not addressed by implementing the response action
selected in this ROD, may present an imminent and substantial
endangerment to public health, welfare, or the environment.
Description of the Selected Remedy
The demolition activities described in this Record of
Decision (ROD) are an interim remedy for the Asarco site. The
interim measures include: demolishing contaminated structures to
clear the site for the completion of the Remedial Investigatio~
and Feasibility Study (RI/FS); preventing the threat of an
uncontrolled smelter stack collapse; and partially controlling
surface water originating off the Asarco property.
The interim remedy will:
Demolish and dismantle certain on-site buildings and
structures other than the stack, that are identified in

-------
conventional trade demQlitian techniques after cleaning
the buildings and removing all aSbestos-containing
materials;
Demolish the smelter stack by implosion using
explosives;
Suppress dust and particulate emissions during
demolition using fogging and misting techniques and to
the extent practicable, encapsulate the interior lining
of the smelter stack.
Collect wastewater from the dust suppression measures
at each demolition site and route collected wastewater
to an on-site wastewater evaporation system;
Monitor ambient air levels during demolition
activities;
Vacuum, sample and decontaminate buildings that are not
demolished or dismantled;
Remove the ship to shore oil line at the central dock
area and ensure any residual oil is not released;
Dispose of uncontaminated wood and combustible
materials which are not dangerous or hazardous waste,
by burning them in an incinerator;
Dispose of steel, concrete, contaminated wood,
asbestos, and other demolition debris in one of the
following ways:
*
temporary storage of debris in the fine ore
bins until selection of the final disposal
remedy (all demolition debris that remains on
site must be stored in the fine ore bins);
*
off-site disposal of debris that is
hazardous, dangerous, or solid waste in an
appropriate disposal facility that is
operating in compliance with applicable
federal and state requirements;
*
salvage for reuse or recycling of
decontaminated material.
Dispose of sludge from the wastewater evaporation
process and dust from vacuuming the on-site structures
by shipment to a metal recovery facility.
Temporarily store stack bricks in the fine ore bins

-------
Implement measures to prevent surface water from
entering the site by' rerouting the water through
diversion ditches and conduits to a permitted outfall
Implement measures to minimize contact of on-site
surface water with newly exposed soils and collect
surface water run-off in the wastewater evaporation
system.
Declaration
This Interim Action is protective of human health and the
environment, complies with federal and state requirements that
are applicable or rele";;ant and appropriate for this remedial
accion, and is "::os~-eff::.ct~.ve. T~is Interim Action utilizes
permanent solutions and alterildtiV'e treatment (or resourct::.
recovery) technologies to the maximum extent practicable given
the limited scope of the action. Because this interim action
does not constitute the final remedy for the site, the statutory
preference for remedies that employ treatment that reduces
toxicity, mobility, or volume as a principal element will be
addressed at the time of the final response action. Subsequent
actions are planned to fully address the principal threats posed
by this site.
Because this remedy will result in hazardous substances
remaining on site above health-based levels, a review will be
conducted within five years of commencement of this interim
remedial action, unless the final remedy for the site has been
initiated by that time, to ensure that the remedy continues to
provide adequate protection of human health and the environment.

ASARCO DEMOLITION
1.
SITE DESCRIPTION AND HISTORY
A.
site Description
The Asarco Tacoma Smelter site (the Site) is part of the
Commencement Bay Nearshore/Tideflats (CB NIT) Superfund Site,
which was listed on the int~rim priority list by EPA in 1981 and
included in the first promulgated National Priorities List (NPL)
that EPA publ if:hed in st:pt':-l11ber 1~93. . The CB NIT Superfund site
i& loca ted in Tacoma, Wasningt",n at. th£. southern end of tJ:A~ mai:n
basin of puget Sound. The Asarco Tacoma Smelter Site, located in
Ruston and Tacoma, Washington, is on approximately 67 acres of
property owned by ASARCO Incorporated (Asarco), a New Jersey
corporation, also known as the American Smelting and Refining
Company. The site is bordered to the north by the shoreline of
Commencement Bay. Surrounding lands are owned by the Town of .
Ruston and the City of Tacoma (Figure 1). The Site is presently
fenced and secured.
Land use adjacent to the Site is primarily suburban
residential, with nearby. recreational (yacht club) and commercial
uses. Single family residences are predominant in the area with
the closest located approximately 300 feet to the west of the
smelter stack. Schools, playgrounds, and parks are also located
within 1 mile of the Site. Ruston, the community west of the
Asarco facility, has a population of approximately 640 within
1/3 mile of the site; the North Tacoma population within a mile
of the Asarco site numbers approximately 3,650. Ruston Way,
which is an access route to the Vashon Ferry at nearby Point
Defiance, runs across the southern portion of the Asarco
property, which includes a tunnel. A rail line operated by
Burlington Northern Railroad also runs across the southern
portion of the site.
The Site includes over seventy buildings and a large stack
that were constructed since the late 1800's for copper smelting
and the refinement of process byproducts. The stack, a brick
chimney which was constructed in 1918, is 562 feet high. During
the period of copper smelting operations, Asarco generated large
quantities of copper reverberatory slag (slag). Historically,
molten slag was poured on the ground and at the shoreline edge as
fill material, which altered the shape of the original shoreline.
Many of the existing structures at the Site were built upon the
fill portion of the Asarco property. The Site area also includes
a pond that was used during plant operations as a discharge point

-------
for cooling water. Since the early 1970's, the pond, which is at
a low elevation, has served as a'natural drainage basin on the
site and receives runoff from about 45 acres of adjacent Asarco
property. .

There are no known wetlands, floodplain zones, or endangered
species at this Site.
B.
site History
During the active industrial life of the Asarco Tacoma
Smelter, the primary product was refined copper. Byproducts of
the copper smelting process~that were produced included sulfuric
acid, liquid sulfur dioxide, arsenic trioxide, arsenic metal, and
copper reverbatory slag. The following is a brief chronological.
summary.of operations a~.the Asarco Tacoma Smelter.' .
Began operation as a lead smelter under the ownership
of the Tacoma Smelter Company.
Copper production started.
Asarco purchased the smelter. .
Plant was rebuilt, stack was constructed,
electrostatic precipitators were added.
Blast furnace smelting operations were discontinued
and replaced with reverberatories that produced slag
as one by-product.
A sulfuric acid plant began producing acid from the
converter off-gases.
The sulfuric plant was enlarged.
A liquid sulfur dioxide plant began operation, using
a dimethylaniline process.
A baghouse was installed to handle dust from the
arsenic kitchen and metallic arsenic plant.
Electrolytic refinery ceased operation.
Copper smelting operations were discontinued.
Arsenic production was discontinued, and facility was
taken completely out of production.

As described above, much of the present facility is built
over fill material, including slag, which was placed by Asarco as
part of the smelter operations. In addition, many of the
structures at the Site are either directly or indirectly in
contact with process materials, including materials containing
inorganic arsenic.

Since January 1987, Asarco has completed initial
stabilization measures at the Site. Facilities in the stack area
associated with copper smelting and the production of both
arsenic trioxide and metallic arsenic were demolished. Since
stabilization began, much of the southern part of the site (where
these facilities were located) has been leveled and, to a minor

-------
extent, graded. Figure 2 [Figure ~-3 from Remedial Investigation
(RI)2 v. 1] shows the site as of January 1989.
II.
ENFORCEMENT ACTIVITIES
The history of regulatory activities affecting the Asarco
Tacoma Smelter began in the late 1960s with the passage of ai~
emission standards by the Puget Sound Air Pollution Control
Authority (PSAPCA). EPA requirements, such as National Pollution
Discharge Elimination Systems (NPDES) permits which regulate
point source water discharges, were applied in 1975.
. .
'"
Although PSAPCA began regulating sulfur dioxide and arsenic
emissions in 1968, v~riances to the standards were granted Asarco
until 1975. EPA beS-"'1 ;:'nforcemp.nt proceedings in the early 1980s
to regulate aJ.r emissions. Fedef~al and state standards and'
variances continued to De issues of contention until the smelter
closed in 1985.
In September 1986, Asarco signed an Administrative Order on
Consent with EPA pursuant to Sec. 106(a) of CERCLA, in which
Asarco agreed to conduct a Remedial Investigation and Feasibility
study (RI/FS) and perform immediate site stabilization activities
at the site. Asarco's contractors began the RI/FS in 1987 under
EPA oversight. Site stabilization, Phase I, removing the most
contaminated buildings around the smelter stack, also began in
1987 and was completed in 1988. Draft RI and FS reports prepared
by Asarco have been submitted to EPA and placed in the
Administrative Record for this site. Information and analyses in
those draft reports is sufficient to develop the interim remedial
action that is selected in this Record of Decision. The field
investigation and evaluation of remedial alternatives for a final
RI/FS is ongoing and will be used to develop a final Site remedy.
In addition to the smelter property itself, Asarco is a
responsible party for three closely related operable units of the
CB N/T Superfund site, known as Ruston/North Tacoma Study Area,
Asarco Sediments and Ruston Expedited Response Action (ERA).
These units are reviewed below in the section "Scope and Role of
Response Action." In March 1989, Asarco and EPA entered into an
agreement for Asarco to conduct the ERA in the Ruston/North .
Tacoma Study Area. The Administrative Order on Consent, issued
under Sec. 106(a) of CERCLA, required Asarco to clean up and cap
11 publicly accessible properties in Ruston. Contaminated soils
excavated from the 10 of the 11 properties are stored temporarily
at the site in a building known as the "fine ore bins building"
until the final remedy is selected for the Site.

-------
III.
COMMUNITY RELATIONS
During its years of operation, the Asarco smelter was the
largest employer in the town of Ruston (which was named after the
smelter's founder). After the smelter's closure in 1986 the
community suffered a loss of 550 jobs and a large tax base. Most
residents feel that the property should be cleaned up and
returned to profitable economic use~ they are also concerned
about public perceptions of their community as a polluted place
where new businesses might not want to locate, and the effect
such perceptions may have on local property values. The Ruston
Town Council passed an ordinance in 1988 prohibiting any
hazardous waste storage or"'disposal facilities within the town
limits. ;;
Throughout EPA's Superfund activities at the Asarco Site, the
Agency has been working to keep the community involved and
informed. EPA and Ecology, with help from the Tacoma pierce
County Health Department, established several local information
repositories. These repositories, listed in Appendix III,
contain information about all of the Asarco related projects
including demolition. In October 1989 EPA hired a community
liaison to distribute information and respond to the community's
questions and concerns. The community liaison has a part-time
local office in Tacoma near the Asarco facility.

EPA publishes fact sheets on a regular basis in order to keep
the community informed of its progress on the Asarco related
projects. A list of fact sheets published to date can be found
in Appendix IV.
Although the fact sheets are an important means of reporting
progress and members of the community find them useful, EPA and
the community felt that more involvement, in addition to
information, was needed. In October 1989, a community workgroup
was formed, primarily to promote involvement in the residential
investigation. However, the group is interested in all aspects
of the Asarco cleanup and has provided EPA with useful feedback
on its activities for the smelter site. EPA first solicited
interest in the group in June 1989 in a fact sheet that was
mailed to 5,000 addresses in the Ruston and North Tacoma area.
The workgroup now has 17 members who regularly attend the monthly
meetings~ however the meetings are open to anyone and other
members of the public attend the meetings as they are interested.

One workgroup meeting (July 1990) focused specifically on the
proposed plan for demolition. The workgroup provided important
feedback as to additional pieces of information they wanted to
see in the proposed plan. EPA was able to incorporate all of the
group's suggestions before releasing the proposed plan for public
comment on July 18, 1990. The plan was subject to public comment
for 60 days and was also discussed at a public meeting on August

-------
16, 1990. All of the comments. received during the period, EPA's
responses to them and changes made to the plan based on those
comments are described in the Responsiveness Summary found in
Appendix I.
IV.
SCOPE AND ROLE OF RESPONSE ACTION
Superfund response actions at the CB N/T Superfund site are
currently coordinated under seven separate operable units (OU).
The interim remedy addressed by this ROD is OU 07 and involves
the demolition of contamin~ted site structures to clear the Site
for completion of the RI/FS and partially controls off-site
surface water at the Site. :The seven operable units making up
the Site are: .

The CB N/T operable units have been designated by EPA over
the course of several years in response to changing project needs
as the agencies develop a better understanding of the overall CB
N/T site. The numbering sequence used to identify each operable
unit is simply chronological, and does not reflect priorities.
Scope Of Current Work:
OU 07. Asarco Demolition - The demolition of structures on
the Asarco Smelter facility addressed by this Record of
Decision is the initial step for this operable unit. This
ROD provides for demolition of structures and the smelter
stack, temporary storage of demolition debris on Site,
incineration of uncontaminated wood debris in a modified
incinerator on Site and the partial control of off-site
surface waters.

OU 01. Nearshore/Tideflats Sediments - The evaluation and
cleanup of 10-12 square miles of shallow water shoreline
located in the active commercial seaport of the City of
Tacoma are being addressed in this operable unit. The marine
boundaries of this operable unit are limited to the
shoreline, intertidal areas, bottom sediments, and water of

OU 02. Asarco Tacoma Smelter - contamination at the Asarco
Tacoma Smelter facility is being addressed by this operable
unit. Initial site stabilization activities removing the
most contaminated structures, but not including the stack, in
the Stack Area (see site Characteristics and Figure 2) was
completed in 1988. The interim remedial work addressed in
OU 07, Asarco Demolition, will be followed by a second ROD
which will select the final remedy for the Asarco Tacoma
Smelter facility, including the final disposal of demolition
debris to be temporarily stored at the site. EPA is the lead
agency for the smelter operable units.

OU 03. Tacoma Tar pits - This former coal gasification
plant is located in Tacoma near the mouth of the Puyallup
River. EPA issued a ROD in December 1987 calling for a
combination of excavation and treatment of the most highly
contaminated soils, capping of the remaining areas of the
Site, and continued monitoring of groundwater near the site.
The unit is now in remedial design phase, with remedial
action scheduled to begin in 1991 for which EPA is the lead
agency.
OU 04. Asarco Off-Property - Federal, state and local
environmental and public health agencies have conducted
extensive studies to determine the risks associated with
arsenic exposure in areas surrounding the Asarco Tacoma
Smelter. In March 1989, Asarco signed a Consent Order
agreeing to conduct an Expedited Response Action (ERA) to
contain contaminated soils in 11 publicly accessible areas.
Work began in November 1989 to remove the top layer of
contaminated soil and cap each area. Excavated soils are
being stored temporarily in the fine ore bins at the Asarco
Tacoma Smelter facility. At present, EPA is conducting an
RIIFS for the remaining areas of concern and expects to issue

-------
a ROD for the remaining remedia~ work in this operable unit
in 1991. EPA is the lead agency.
OU 05. Nearshore/Tideflats Sources - This operable unit
addresses the identification and control of sources of

sEdiment problem ar3a a::;30c.i~ted ~ith th~ .A~::trc'~ facility.
exhibited different characteristics that needed further study
before remedial action selection. EPA is the lead agency and
is currently preparing a supplemental FS for the unit.
EPA decided to take the early action to demolish structures
It the site for several reasons. First, evaluations under the
~I/FS work at the Site suggest that many of the Site structures
lre constructed over contaminated materials. Removal of the
>tructures will be necessary in order to fully characterize the
lature and extent of contamination and ultimately address the
:ontamination in the final remedy for the Site. This action also
Till eliminate the threat of an uncontrolled smelter stack
:ollapse. Studies submitted by Asarco indicate evidence of
>erious deterioration of the stack. Weathering .of the cement
tortar has caused the stack to become increasingly unstable.
~herefore, this interim remedial action will control risks at the
lite while the RI/FS is being completed and in advance of EPA's
.election of a final remedy for the site.
For these reasons, EPA has determined that the interim.
lctivities selected in this ROD will contribute to the efficient
)erformance of the long-term remedial actions for the site. As
:he NCP states, sites should generally be remediated in operable
Lnits when early activities are necessary or appropriate to
lchieve significant risk reduction quickly and to expedite
:ompletion of a total site cleanup. Based on evaluations
:onducted under the RI/FS, this interim action operable unit is
leither inconsistent with nor will it preclude implementation of
llternatives being evaluated for the final remedy.

SITE CHARACTERISTICS
There are six functional divisions within the smelter
complex, each used for specific plant activities during its
operation, as illustrated in Figure 3j. They include:
Stack Area
Plant Area
Cooling Pond
Administration
Central Site
Lower site
Area
The fOllowing is a brief:;description of each area on the
Site.
1~e Stack ~rea now includes-the 562. foot brick chimney stack,
which has an outside diameter of 50 feet at the base and 27
feet at the top. A number of structures previously in this
area (electrostatic precipitators, baghouse, flues, arsenic
kitchens, Godfrey roasters, .and the metallic arsenic plant)
were demolished during the first site stabilization effort in
1987. The ground in this area is a relatively steep slope
starting at the stack and grading down into a flat zone in
the plant area. The area south of the stack is gently sloped
and was not used for plant processes.
The Plant Area includes the converters, reverberatory
furnaces, and Hereshoff roasters. This part of the site is
relatively flat.
The Coolinq Pond area was originally used as a water source
for cooling the anodes coming off the anode furnace. After
water was sprayed onto the anodes, the contaminated water was
drained into a pit and then pumped back to the cooling pond.
Since the early 1970's, the pond was used only as a natural
drainage basin on the site. The pond is in a low elevation
topographic area that receives runoff from about 45 acres of
property in Ruston and North Tacoma that are adjacent to the
Site.
The Administration Area includes the main offices,
'laboratory, engineering building, and parking lots.
The Central site is the transition zone between the upper
Site (stack and plant areas) and the lower site. It includes
the refinery buildings and fine ore bins building. Much of
this part of the Site is paved.

The Lower Site, which is the northern boundary of the site
along the shoreline of Commencement Bay, was primarily a
staging and transport area that includes docking facilities,

-------
rail lines, and a limited number of buildings. It is very.
flat, predominantly paved, "and is built over the slag fill
that was deposited over the original shoreline.
As a copper smelter and refinery, the principal contaminants
of concern at the site are metals. Specifically, these metals
include antimony, arsenic, cadmium, chromivm, copper, lead,
mercury, nickel and zinc. Dimethylaniline (DMA) which was used
to manufacture liquid sulfur dioxide, has been found in the
groundwater at the Site.
Arsenic, cadmium, chromium, copper, lead, mercury, nickel,
and zinc are hazardous substances as defined in section 101(14)
of CERCLA. .
Soils and fill material on sit~ are co~tamin~ted wi~r a
variet~. cf "'ttL~~ me~als l.i:;te~ a';)ove as wt:J 1 as with some or:::J~:ni:..
chemicals such as polyaromatic hydrocarbons and polychlorinated
biphenyls (PAR's and PCB's). The organic contamination is
limited to small areas of the site. The metals contamination
varies both horizontally over the Site surface and with depth.
The many buildings and structures on site vary in condition.
Due to the nature of plant operations, accumulations of dust are
present in varying degrees on building materials and equipment in
many of the buildings, including dust contaminated with arsenic
and other metals. Most reusable equipment has been removed.
ASbestos-bearing materials have been removed from many of the
buildings, under EPA order or PSAPCA permit.
The stack, which is built of bricks, has become seriously
deteriorated, especially in areas near the top of the stack.
Studies performed by Asarco indicate that chimney bands are
broken or deteriorated, the stack bulges from the 540-foot
elevation to the top, and the liner has fallen in several places
and has blisters. Weathering and sulfation of mortar joints has
added to the instability of the structure. Analysis of brick
contamination found arsenic, cadmium, copper, lead, and zinc at
significant levels. The sample results (letter from Mr. Thorp,
attorney for Asarco, to Mr. Rose, EPA Project Manager, May 11,
1989) are as follows:
Arsenic

much of the soils and exposed surface-area "of the Site are
contaminated, the movement of surface water picks up and
transports contaminants. Some surface water flows into the
unlined cooling pond where sediments settle out.
Since
The available geologic and hydrogeologic data from the- RIfFS
indicate the potential for surface contamination to migrate to
the water table. Water balance estimates indicate that
precipitation falls on the site to recharge the groundwater even
though much of the precipitation falls on paved areas and is
collected before infiltration into the subsurface. In addition,
surface water run-on from property near the Site and surface
water that collects in the cooling pond has the potential to
leach into the groundwater. "Available data indicate that
ground~ater beneath the Asarco facility flows toward Commencement
Bay.
Presently, off property surface water run on enters the Site
at two locations. The majority of off property run on comes from
a 45-acre area west of the Site that drains into a bypass channel
around the cooling pond, or into the cooling pond, and then
discharges to the site's middle outfall to Commencement Bay. The
second location is at the south end of the site along Ruston Way.
An off-site sub-basin drains down the hillside, onto the Site via
at least four culverts passing under Ruston Way, and discharges
by one of the Site outfalls to Commencement Bay. Currently there
are three NPDES permitted outfalls on Site and two storm water
outfalls in the vicinity of the Asarco facility. The northern
and southern most outfalls are not located on Asarco's property
and are not regulated by NPDES permits. The three NPDES permitted
outfalls located on the site are between these two unregulated
outfalls.
The majority of surface water runoff on-site is channeled and
directed to the existing storm water drainage system. Runoff is
generally collected in catch basins, conveyed to the storm drain
system, and finally discharged to Commencement Bay through three
on-site outfalls that were permitted under the NPDES Permit
System when the facility was active. Asarco was granted NPDES
permits in 1975 which were extended by the Department of Ecology
in 1980. Monitoring of surface water discharges from these
outfalls found, but did not limit, high concentrations of total
and dissolved metals, including arsenic and copper, at levels
exceeding water quality standards. There are indications that
the integrity of the storm drain system is failing. Part of the
surface water is also collected and sent to an on-site wastewater
evaporation system. As part of the first site stabilization
effort in 1987, a surface water runoff collection system was
installed at the newly graded area below the stack and from the
acid plant area. Collected water is routed to the evaporation
system. Water created in dust suppression activities during

-------
demolition will be diverted to this on-site system.
. .
VI.
SUMMARY OF SITE RISKS
The following qualitative risk information demonstrates that
the actions contemplated by this interim action ar~ necessary to
stabilize the site and prevent iurther degradation. This interim
ac~ion will address Site risks and cleanup objectives associated
with buildings and structures, including the stack. In addition,
this interim action partially addresses the potential risks from
uncontrolled surface water runoff by addressing off-property
surface water run on. The'final ROD will further address on-
site runoff. The complete RI/FS that is ongoing will evaluate
the potential hazards associated with contaminated soils beneat~£
o~ surrounding th2 build~ngs and stack, f~\l materials, Bit~
5u:o=fac-=. water, ,i~d g"!:"~\und..-ater. A ~as2lin.:. ris~: assessment
adaressing site-wide conditions is a part of the overall RI/FS;
draft reports are part of the Administrative Record. When
completed, the RI/FS will support selection of a final remedial
action for this operable unit to address the remaining risks.
At the Asarco smelter facility there are several migration
and exposure pathways of contaminants which will be partially
addressed by this interim remedial action. Because this was a
copper smelting facility, the contaminants of concern include
arsenic, other metals and byproducts of the copper smelting
process that are present at the site in soils and fill materials,
in dust on or within buildings, and in building materials. Many
of these contaminants are toxic to humans and aquatic life
including:
Arsenic
The adverse health effects from exposure to arsenic have been
confirmed in numerous public health and scientific studies.
Arsenic can cause a variety of toxic effects in humans with the
type and severity of effects depending upon the level of exposure
and form of arsenic. Inorganic arsenic is a human poison and
large doses can cause death. Human exposure to lower levels of
arsenic has resulted in injury to a number of body tissues and
organs, including the liver, kidneys, nervous system, skin, and
an increased risk of developing lung and skin cancers. This
increased risk of lung cancer has been observed in numerous
studies of workers who inhaled arsenic in smelters and in a
pesticide plant. Increased incidence of skin cancers have been
found in people who have consumed drinking water contaminated
with arsenic (for example, in Taiwan and Mexico) and in those who
used medicines containing arsenic.
Antimony
Antimony exposure has been associated with an increase in
lung cancer. Animal studies yielded suggestive evidence that

-------
antimony trioxide causes lung and liver tumors. Female workers
exposed to antimony compounds had an increased incidence of
gynecological disorders and spontaneous abortion.

Cadmium
Cadmium is relatively mobile in the aquatic environment.
Cadmium is a known carcinogen to animals, and potentially to
humans, exposed by inhalation. There is evidence linking cadmium
with cancer of the prostate in humans.
studies suggest that cadmium may have adverse effects on
reproduction in fish at levels present in lightly to moderately
polluted waters.
Chromium
Hexavalent chromium (Cr IV) is rather soluble and is quite
m~bile in groundwater and surface water. In the presence of ~.
reducing agents it is rapidly converted to trivalent chromium (Cr
III), which is strongly adsorbed to soil components and
consequently is much less mobile. Sources of chromium in air.
include windblown soil and particulate emissions from industrial
processes. Inhalation of Cr VI salts causes irritation and
inflammation of the nasal mucosa, and ulceration and perforation
of the nasal septum. Hexavalent chromium causes kidney damage in
animals and humans. The liver is also sensitive to the toxic
effects of Cr IV, but less so than the kidneys or respiratory
system.
Cr III appears to be more acutely toxic to fish than Cr VIi
the reverse is true in long term chronic exposure studies.
copper
Because copper compounds and complexes are readily soluble,
copper is very mobile in soil and other surface environments, and
is adsorbed to organic matter, clays, and other materials. It is
toxic to humans at high levels causing irritation following acute
exposure and anemia following chronic exposure. Exposure to
metallic copper dust can cause a short-term illness that is
characterized by chills, fever, aching muscles, dryness of mouth
and throat, and headache. Copper is very toxic to aquatic
organisms.
Lead
There is suggestive evidence that some lead salts are
carcinogenic, inducing kidney tumors in mice and rats. Exposure
to lead has been linked to reproductive risk and it can adversely
affect the brain and central nervous system. Chronic exposure to
low levels of lead can cause subtle learning disabilities in
children. Exposure to lead can also cause kidney damage and
anemia, and it may have adverse effects on the immune system.

-------
Nickel .
. In a number of epidemiological studies, occupational exposure
to nickel compounds has been associated with excess cancer of the
lung and nasal cavity. Several nickel compounds are mutagenic
and can cause cell transformation. In humans, nickel and nickel
compounds can cause a sensitization dermatitis. The chronic
toxicity of nickel to aquatic organis~s is high.
zinc
Ingestion of excessive amounts of zinc may cause fever,
vomiting, stomach cramps, and diarrhea. High levels of zinc in
the diet have been shown tp also retard growth and produce
defective mineralization of bone. Zinc may be indirectly
important with regard to cancer sinfe its presence seems to be
necessary for the growth of tumors.
E>:~c::;u'r'':: :?a~hwavs
The existing buildings and structures contain dust and
building materials contaminated from exposure to industrial
activities at the site. Air movement can release particulate
matter which may be transported off Site by winds. Particulate
matter can also settle to the ground and contaminate soils and
dusts off site. People can be exposed by inhaling or ingesting
contaminated particulate matter. contaminated building materials
may present risks from direct contact.
The smelter stack presents additional risks. Evaluations of
the stack's structural integrity found serious deterioration.
The results of a field investigation by Asarco's consultant,
which was presented in detail in an engineering report prepared
in 1986 by Industrial Chimney, Inc. (Site Stabilization Plan,
Phase II, Appendix C) indicates that the stack, particularly the
upper section, has deteriorated considerably because of weather
and sulfation of the mortar joints. If the stack was to fall
without controls there would be a substantial risk of injury or
death for the on-site personnel and the closely located
residences. In addition, exposure from inhalation of stack
contaminants released into the air during an uncontrolled stack
collapse could occur for both on-site personnel and people living
in the community (approximately 35 homes are within 1000 feet of
the stack). The contaminants also could settle in the nearby
residential areas, and present risks from direct contact or
ingestion, and from inhalation of resuspended soils and dusts.

-------
A significant portion of the ~urfac~ water at the site flows.
into the site from the 45-acre off-property drainage basin to the
west of the Asarco property. Much of the surface water runoff
enters storm water drainage conduits existing at the Site, which
discharge to Commencement Bay via three outfalls. However, the
integrity of portions of the drainage system is in doubt. .
Several observations based on drainage flows suggest that surface
waters are entering the groundwater via breaks in the system.
. Thus, the site evaluation indicates that contamination in surface
water at the site is being transported to groundwater. Much of
this contaminated groundwater beneath the facility flows toward
Commencement Bay and may be exceeding EPA's water quality
criterion and the state's water quality standards. This may
result in risks to aquatic life and to humans who may be eating
aquatic life from Commencement Bay.
Actual or threatened releases of ha~ardous substances from
this Site, if not addressed by implementing the interim response
actions selected in this ROD, may present an imminent and
substantial endangerment to public health, welfare, or the
environment. .
VII.
DESCRIPTION OF ALTERNATIVES
The scope of the interim remedial action at the Asarco site
is limited and few alternatives were evaluated. For one of the
actions, the removal of existing buildings and structures other
than the stack, EPA considered only conventional trade and
protective techniques to dismantle and demolish buildings (see
section A below, "Structure Demolition"). Although the
evaluation of approaches for demolishing the stack analyzed
several alternatives, only one approach was considered effective
and implementable due to the height of the stack and lack of
stability (see section B below, "Alternatives for Stack
Demolition"). Several options for disposal- of debris were
considered, but the decision for permanent disposal of material
that cannot be reused, recycled or burned on site will be made in
the final ROD for Operable unit 02, Asarco Tacoma Smelter. only
one approach to divert surface water from flowing on-site was
developed in the draft Feasibility Study. Descriptions of the
alternatives follow.
A.
Structure Demolition
No Action
. The Superfund program requires that the "no-action"
alternative be considered at every site in addition to a range of
treatment and containment alternatives. "No action" would mean
that the structures would not be removed thereby impeding the

-------
sampling and analysis necessary to 90mplete the RIfFS. "No
action" and also would result in contaminants remaining on-site
which could be resuspended and released off site.
Conventional Demolition
All buildings indicated in sections 2-10, see Figures 3a-i,
will be demolished or dismantled by conventional and protective
methods. In an effort to be consistent, the areas and specific
buildings affected are summarized in Appendix V using the numbers
and order assigned to them in the site Stabilization Plan.
However, the buildings will not necessarily be demolished or
dismantled in the order liSted in Appendix V. The order for
demolition will be based on ,access needs for further sampling,
and other on-site considerations.
?ri~r to dcill0liLlon, buildings and str~~tu~~ will be
vacuumed and washed to remove dust, and aSbestos-containing
materials will be removed. Proper notification procedures, in
accordance with the asbestos National Emission Standards for
Hazardous Air Pollutants (NESHAP), will be followed. Areas of
structures containing dust that are inaccessible for vacuuming
will be washed down to curtail dust emissions. During
demolition, dust suppression measures using high pressure water
fogging and misting devices will be utilized to control the
release of dust and particulates. containment systems to collect
water from the dust suppression measures will collect the waste
water and route the waste water to the evaporation system. These
systems will meet EPA requirements.
This ROD does not call for the demolition of certain
structures. Some of these structures, such as those in Section
9,will remain for continued storage and others, such as those in
Section 5, will remain to act as retaining walls for terraced
portions of the Site. Structures not listed in Appendix V will
be vacuumed, emptied and washed down. Footings, pads, and other
support structures for some of the dismantled buildings will
remain on Site until the final remedy is selected. The following
is a list of the buildings, as represented in the site
stabilization plan, that will remain on site after demolition
activities are finished.

B.
Alternatives for Stack Demolition
For Section 1 (see figure 3k), the smelter stack, five
demolition techniques, and two other alternatives, were
evaluated. Three of the techniques involved different types of
manual demolition with the'~se of scaffolding equipment. Also
evaluated were mechanical demolition, with a crane and heavy
metal ball, explosive demolition, by implosion, cleaning the
stack and no action. .
No Action
The Superfund program requires that the "no-action"
alternative be considered at every site in addition to a
range of treatment and containment alternatives. No action
for demolition of the stack would not stabilize the
deteriorating stack nor alleviate the threat of uncontrolled
collapse (see Section IV above, "Summary of Site Risks").
Cleaninq The Stack
Washing or encapsulating the inside of the stack could
possibly contain dust and prevent air releases. However,
this approach would not eliminate all of the risks from an
uncontrolled collapse posed by the deteriorating stack. A
study, completed by Industrial Chimney, Inc., identified no
practical method for washing that would eliminate
contamination.
Manual Techniques
Several techniques for manually dismantling the stack were
evaluated. All approaches were rejected because they are not
technically feasible for a chimney structure that is 562 feet
high. Pole scaffolding is prefabricated out of metal tubing
and secured to the outside of the stack. Pole scaffoldings
for heights over 125 feet must be designed specifically for
the project. CUrrently there are no specifically designed
pole scaffoldings that have exceeded 250 feet, and it is
expected that this is an upper limit, according to Industrial
Chimney, Inc. Outrigger scaffolding is attached directly to
the stack using cables wrapped around the stack. To use this
method safely approximately 60 feet of the upper stack would
need to be reinforced. A second layer of board and cables
would then be required at each scaffolding level. Mechanical

-------
Scaffolding is similar to that used by window washers on
high-rise buildings. The scaffola is supported by hangers
(stirrups) at two points, suspended from overhead supports to
permit the raising or lowering. Because the upper portion of
the stack is not secure, this technique is not technically
feasible.
Mechanical Techniaue
Mechanical demolition involves the use of a crane and heavy
steel ball to batter the stack into pieces. This technique
is not feasible for the stack since a typical height limit
for this type of demolition is around 100 feet.

Exp!r..)sive Demolition (ImDlosion)
Control-Ie.1 e~~F'!os::":e demol~.ti~n ~sing implo~iOl. inv()lv~3
drilling holes in tne base of the stack and placing
explosives in these holes. This method has been used
extensively on stacks in the past. Prior to demolition, the
interior of the stack is encapsulated to minimize the release
of soot and contaminants on the surface of the lining. A
lined and bermed trench will be constructed at the base of
the stack to contain the falling bricks and the water
generated from the dust suppression activities (described in
detail in section IX.B.2.b, "Description of Remedial
Component").
C.
Disposal of Debris
various types of debris will be generated during the
demolition of structures including wood, steel, brick,
fiberglass, asbestos materials, flue dust, and other
miscellaneous materials. The following is a brief review of
disposal options for the primary types of material to be
generated. This interim remedial action relies on one
alternative for the temporary storage on site of all hazardous
debris, and several alternatives for the disposal of wastes that
are not hazardous or dangerous, pending selection of a permanent
disposal remedy in the final ROD for the smelter Site.2 Federal
land disposal restrictions (LDR) will not apply to the on-site
storage within the area of contamination of hazardous waste (see
53 FR 51444, December 21, 1988). Off-site disposal for hazardous
wastes, solid wastes, fiberglass, and asbestos may be approved as
2Hazardous waste is defined
dangerous waste is defined in
Regulation, WAC 173-303-040 (18).
in 40 CFR section 261.3 and
Washington's Dangerous Waste

-------
a permanent disposal measure where appropriate. To the extent
LDR applies to the materials shipped off site for disposal which
are not covered by a national capacity variance for debris, the
materials must either comply with the applicable treatability
standard' or must be the subject of a treatability variance. In
addition, materials may be approved for reuse or recycling.
1.
Disposal options for materials other than stack debris.
a. Temporarv storaae of debris in the fine ore bins
until selection of a permanent disposal remedy. The fine ore
bins are in a large building on site with adequate capacity to
store debris materials that :;can protect materials from
precipitation and wind erosion, and prevent the migration of
conta.mination into the envirc!1J11ent. If storage in this bui~.ding
wi:!.l meet the substantive requirements for waste pile storage, .
this option provides a cost-effective storage solution until the
permanent disposal remedy is selected (see footnote 5 below).
b. Disposal at an off-site facility operatina in
compliance with applicable federal and state reauirements.
Demolition debris can be shipped off site for disposal in an
appropriate facility, depending on the nature of contamination.
All material would undergo a waste analysis prior to shipment off
site. EPA would ensure that any off-site disposal destination is
operating in compliance with applicable federal or state laws and
EPA's off Site disposal policy before the material is shipped.
Hazardous waste must be disposed of at a hazardous waste disposal
facility; dangerous waste would be disposed of in an appropriate
facility. (See page 17, footnote 1.) The appropriate facility
would depend on whether the disposal site is in the state of
washington, and whether the waste is also a hazardous waste.
ASbestos-containing materials will be disposed at a facility
operating in accordance with National Emission Standards for
Hazardous Air Pollutants (NESHAP) regulations and applicable
state law. Waste materials that qualify as solid waste only may
be shipped off-site for disposal at a solid waste facility.
Proper off-site disposal of the debris would be the final
response for that debris.
c. Reuse or recvclina of the material. A number of
materials at the site will be evaluated to determine if they can
be adequately decontaminated, if necessary, and then reused or
recycled. Steel, wood and other materials that meet
decontamination requirements approved by the EPA during remedial
design, can be salvaged for reuse. Steel can be decontaminated
by high pressure washing, or by other procedures approved by the
EPA. - Steel may need to be decontaminated before being recycled
by batch melting or resmelting at an off-site facility. Wood
that is a dangerous or hazardous waste must be decontaminated
before reuse. Wood decontamination procedures, such as removing
18

-------
the exterior of the wood by pl~ning, will also be subject to .
approval by the EPA. Lead collected in dust and wastewater
sludge could also be recycled by resmelting at an off-site
facility.
d. On-site incineration of wood that is not a hazardous
waste or a danaerous waste. A former production vessel, called a
converter, is available at the site. The converter can be
modified to incinerate wood that is neither a hazardous waste nor
a dangerous waste. Wood that is a hazardous or dangerous waste
will be temporarily stored in the fine ore bins building until
final disposal or treatment is selected as part of the final
remedy. .

Although under CERCLA ~ i21(e), permits are not required for

withdraw its authorization, any activity involving the converter
must comply with substantive requirements under federal or state
laws and regulations.

Disposal alternatives for stack debris
Demolition of the smelter stack will generate 12,000 to
15,700 cubic yards of debris, primarily brick with varying levels
of contamination. There were several alternatives evaluated for
the temporary and permanent disposal of this debris pending
selection of the final remedy for the smelter site.
a. On-site storaae in place
A temporary storage facility would be created from the trench
and bermed area in which the stack debris is expected to settle
following the explosive demolition. since this debris will
contain hazardous waste and dangerous waste, the storage area
design would be evaluated for compliance with the federal and
state requirements for a waste pile (40 CFR Part 264, Subpart Li
WAC 173-303-660). Specifically, the waste pile would have to be
protected from water run-on and wind erosion, and a sufficient
liner and leachate collection system would be required.
Groundwater monitoring wells would be placed up and down gradient
of this area. Covered demolition debris would stay in place
until a permanent solution for debris disposal is decided upon in
the ROD for complete site remediation.
b. On-site storaae in the fine ore bins buildinq
The fine ore bins building is a large building that is
presently being used to temporarily store soils excavated from
the Ruston Expedited Response Action. After demolition of the
smelter stack the contaminated bricks would be moved by truck
19

-------
within the area of contamination ~rom the stack area to temporary
storage in the fine ore bins building. Temporary storage in this
building will meet the requirements for a waste pile (see
footnote 5 below). The stack debris would stay in the fine ore
bins building until a permanent solution for debris disposal is
decided upon in the ROD for complete site remediation.
c. Off-site disposal
Under this alternative, stack debris would be transported to
an approved waste facility. Whether the materials were shipped
to a hazardous waste or a solid waste facility would depend on
analysis of the debris contamination. This alternative provides
permanent disposal for the "stack bricks after the stack's
demolition. :
D.
Surface Water Controls
a. No Action
The no action alternative for the partial control of surface
water from the adjacent area off-property would not prevent
contaminant transport. Surface waters must be diverted from
flowing on the smelter facility because precipitation contact
with newly exposed surfaces must be minimized to prevent further
contamination to groundwater aquifers and Commencement Bay.
b. Diversion
The draft Feasibility Study (FS) evaluated in detail only
one alternative to divert and control surface waters from the 45-
acre drainage area adjacent to the site (see Alternatives JA,
4 . lA, and 7 A) .
The surface water run on from areas adjacent to the Asarco
facility would be diverted before entering the Site and directed
to off-property storm water outfalls (the northern or southern
most outfalls discussed in site Characteristics). Diverting the
surface water before the on-site demolition activities will
reduce the potential problems of increased contamination from the
newly exposed surfaces on Site. Reducing the volume of surface
water on Site will also reduce contaminant loading to the
groundwater aquifers on site. In the draft Feasibility Study for
this site, the diversion of run-on surface water was included as
a component of each remedial alternative that was analyzed in
detail.
c. On-site surface water collection
On-site water that results from precipitation and dust
suppression activities, during the stack demolition and cleaning
and demolishing the structures, will be controlled to the extent
practicable. Surface water coming into contact with the newly
exposed soils will be channeled into the sedimentation basins and
collected for treatment in the wastewater evaporation system.
Other surface water controls to minimize the potential for

-------
contaminant transport and pot~ntial.soil,erosion may include:.

- Soil covers/tarps
- Soil sealant/binders
- Surface water diversion ditches
- Soil berms/containment structures .
- Grouting key drains to re-route potentjally contaminated
surface water to the water evaporation system.
VIII.
COMPARATIVE ANALYSIS OF ALTERNATIVES
,
The National contingenC;;y,plan (NCP) requires that each
analyzed remedial alternati~e be evaluated according to specific
criteria. The purpose of this evaluation is to promote .
con~istent id~ntific('l.tion of the relat.i'~e advantages an~
disadvantages of each alterl1ative,ther.aby ensuring compliance.
with CERCLA requirements and guiding selection of remedies
offering the most effective and efficient means of aChieving site
cleanup objectives. There are nine evaluation criteria by which
feasible remedial alternatives -are judged. While all nine
criteria are important, they are weighted differently in the
decision-making process. Threshold criteria are used to
determine whether an alternative meets a required level of
performance. Primary balancing criteria are used to evaluate
technical, economic, and practical realities, and modifying
criteria require consideration of state and community concerns.
The nine criteria are:
Threshold Criteria
1. Overall Protection of Human Health and the Environment
2. Compliance with Applicable or Relevant and Appropriate
Requirements (ARARs) under federal or state
environmental laws
Primary Balancinq criteria
3. Long-Term Effectiveness and Permanence
4. Reduction of Toxicity, MObility, or Volume
5. Short-Term Effectiveness
6. Implementability
7. Cost
Modifyinq criteria
8. State Acceptance
, 9. Community Acceptance

-------
THRESHOLD CRITERIA
The remedial alternatives for this interim action were first
evaluated in relation to the threshold criteria: overall
protection of human health and the environment and compliance
with ARARs. The threshold criteria must be met by the potential
alternatives before further consideration as remedies for the
Record of Decision.
1. Overall Protection of Human Health and the Environment
This criteria addresses'.'whether or not remedial actions
provide adequate protection :;and describes the mechanisms for
controlling risks for the different exposure pathways.
The no action alternative would not be protective of human "
health and the environment because it would not stabilize the
Site, prevent an uncontrolled collapse of the smelter stack, or
control surface water run on from the adjacent property. The no-
action alternative neither reduces the magnitude of contamination
found on site nor the likelihood of exposure to site contaminants
and thus is not considered protective of human health or the
environment.
The demolition of structures and the smelter stack at the
Site will be protective of human health and the environment by
removing the threat of an uncontrolled stack collapse, by
removing contaminated structures and by allowing the final RI/FS
to be completed so that final Site cleanup can begin.
The conventional demolition techniques for dismantling
buildings and other structures, the only alternative evaluated,
will be performed in a manner that is protective by first
cleaning the buildings and then using dust suppression measures
during the demolition activities. Any water generated during the
dust suppression activities will be collected to prevent release
into the environment. The effectiveness of dust suppression
activities will be evaluated with ambient air monitoring.
The explosive demolition technique for controlled implosion
of the stack, which was the only technically feasible and/or safe
alternative, will be implemented in a manner that minimizes
releases to the environment and threats to worker safety and
health. Of the alternative techniques for demolishing the stack,
implosion of the smelter stack is the most protective by posing
the least risk to on-site workers. The other alternatives, which
may not be feasible, involve attaching scaffolding to, and
suspending workers from the unsafe chimney structure, thereby
exposing them to unacceptable risk. The explosive demolition
alternative, using implosion, includes encouraging voluntary
evacuation of residents from approximately 35 homes within a

-------
1,000 foot radius of the stack to ensure minimal risk. Dust.
suppression measures during the expiosive demolition would be
effective in reducing dust emissions during the action. Air
monitoring stations would be in operation at least 24 hours
before, during and after the actual demolition of the stack to
ensure that dust suppression is effective in minimizing releases
of particulates and fugitive dusts.
All of the potential disposal options would be effective in
eliminating the risks from contaminated materials that will be
generated by the demolition. In-place temporary storage of the
stack bricks created from the lined trench and bermed area, in
which the stack debris is expected to settle, would be protective
of human health and the environment. Since the debris will
contain hazardous waste and dangerous waste, the storage area
design would be in compli~nce wir.h the waste pile ~cquirements.
A large secure building that will meet waste pile
requirements, known as the fine ore bins, could be used for
temporary storage of demolition debris until selection of a
permanent disposal remedy. The building will protect the
materials from exposure to the environment and reduce the
potential for their release. Both of the temporary storage
options, in-place storage or the fine ore bins building, would
require that the stored materials be moved to a final disposal
location in the future, therefore requiring the contaminated
materials to be double handled. This procedure is not protective
of human health: however a dust suppression protocol and a
protective level of worker safety will be required. Permanent
disposal in an approved off-site waste facility would provide the
most protection to human health and the environment.
Wood that is not a hazardous or dangerous waste or that
cannot be salvaged for reuse, will be burned on Site in an
incinerator. EPA will authorize under CERCLA ~122 (e) (6)
operation of the incinerator in compliance with a PSAPCA permit.
If authorization under ~122 (e) (6) is withdrawn, operation of the
incinerator will comply with federal and state ARARs. Waste
materials to be disposed of off Site will be analyzed to
determine if the waste should be sent to either a hazardous waste
or solid waste disposal facility.
2.
Compliance with ARARs
Compliance with ARARs required an evaluation of each
alternative to determine compliance with action-, chemical-,
location-specific ARARs (or justification for a waiver), and
whether the remedy adequately considers other criteria,
advisories, and guidelines.
23

-------
As more fully described below, EPA identified several ARARs
involved in this interim action. . All alternatives are expected
to be able to comply with ARARs. Materials and debris generated
by the demolition activities will be tested to determine whether
the materials are considered federal hazardous wastes or state
dangerous wastes. Under state regulation, wastes containing
greater than 100 ppm of arsenic are regulated as dangerous
wastes. Handling, storage and management of the materials to be
stored on site or shipped off site for disposal that contain
hazardous or dangerous waste will be governed by the appropriate
federal or state hazardous waste regulations. Specifically,
regulations establishing r~quirements for waste piles are
relevant and appropriate to on-site storage of hazardous waste.
Federal and state land disposal restrictions (LDR) will not apply
to the on-site storage of hazardous wastes because the hazardous
wastes have merely been picked up and consolidated within the
.area of contamination (53 FRo 51444, December 21, 1988).. To the-
extent LDR apply to the materials shipped off site for disposal
that are not covered by a national capacity variance for debris,
the materials either must comply with the applicable treatability
standard or must be the subject of a treatability variance.
The incineration of wood in the modified converter will only
proceed if the wood is not a hazardous or dangerous waste. EPA
will authorize under CERCLA ~122 (e)(6) operation of the
incinerator in compliance with a PSAPCA permit. If authorization
under ~122 (e) (6) is withdrawn, operation of the incinerator will
comply with federal and state ARARs. If the incinerator cannot
comply with the legal requirements, the wood will be either
temporarily stored on site or shipped off site for disposal as a
hazardous waste or a solid waste.
Surface water from off property will be diverted away from
the Site to existing city storm water outfalls to Commencement
Bay. Discharges to surface waters of the state are. regulated
under the state Waste Discharge Permit Program (WAC 173-216)
unless the National Pollutant Discharge Elimination System Permit
Program (NPDES) (WAC. 173-220) applies. Both programs require
technology-based treatment and compliance with water quality
standards. For storm water discharges, the state considers Best
Management Practices (BMP) to constitute all known, available,
and reasonable technology (AKART). Source control BMPs include
measures to prevent the storm water from being contaminated in
the first place. The remedial alternatives will divert the
surface water from running over the site, thus meeting BMPs and
AKART.
ARARs related to disposal activities are described in section
X below.

-------
PRIMARY BALANCING CRITERIA
For those alternatives satisfying the threshold criteria,
five primary balancing criteria are used to evaluate other
aspects of the potential remedies. No one alternative will
necessarily receive the highest evaluation for every balancing
criterion. This phase of the comparative analysis is useful in
refining the relative merits of candidate alternatives. The five
prima~ balancing criteria are: long-term effectiveness and
permanence; reduction of toxicity, mobility, or volume through
treatment; short-term eff~ctiveness; implementability; and cost.
3.
Lonq-Term Effectiveness and Permanence
T~is criterion evaluates the ability of a ~emedia~
c..lternativc to mairltain l:eliable p:cotection of human health and.
the environment over time, once cleanup goals have been achieved.
since this interim remedial action will be followed by a final
ROD for the permanent remedy, clean-up goals are not being set.
EPA intends that this interim remedial action will facilitate the
performance of the final remedy selected for the Site.
The no action alternative would not result in acceptable risk
reduction as judged by the baseline risk assessment in the
Remedial Investigation. This alternative also does not address
the risk of an uncontrolled smelter stack collapse as a result of
its current instability nor does it control the washing of
contaminants into surface water.
Several components to the remedy include permanent features
and were the only alternatives considered. The demolition of
structures and secure storage or disposal will be effective in
eliminating the threat that contamination contained in the
structures will migrate into the environment (see Exposure
Pathways Study).
with regard to the stack, each demolition alternative would
permanently prevent the uncontrolled collapse of the unstable
smelter stack. The disposal alternatives for stack debris
include two temporary measures and the permanent, off-site
disposal measure. In-place containment of the stack bricks after
they fall could be effective in preventing releases to the
environment if the measure was constructed in conformance with
hazardous waste pile requirements. However, the "in-situ"
containment facility would also require construction and
maintenance of a leachate collection and monitoring system in an
area that presently has minimal contamination. This monitoring
system is required for in-place storage, and not for the fine ore
bins building storage, because water will be generated by dust
suppression activities during the stack demolition and for
effectively monitoring the impact of the falling bricks on the

-------
plastic iining covering the trench. An "in-situ" contaimv.ent
area presents some uncertainty of' effectiveness, in terms of a
potential addition to surface and groundwater contamination, even
in the near-term, until sel~ction of the final disposal remedy.
storage of the materials in the fine ore bins, which has
adequate capacity and will protect the materials from surface
water run-on, precipitation and wind, will provide a more
effective long-term storage area. Off-site disposal of the
debris in an appropriate hazardous or solid waste facility would
provide a permanently effective remedy. The final remedy for the
storage of demolition debris will address long-term
effectiveness. .

On-site incineration of the wood will permanently dispose of
the materials. To the extent that materials are shipped off site
fDr disposal, the action will permanently and effectively
eliminate anyon-site risks. Materials suitable for
decontaminating, reuse or recycling will be permanently removed
from the Site.
4. Reduction of Toxicitv. Mobilitv. or Volume throuqh
Treatment
This criterion evaluated the anticipated performance of the
various treatment technologies and addressed the statutory
preference for selecting remedial actions that employ treatment
technologies which permanently and significantly reduce toxicity,
mobility, or volume of the hazardous substances. This preference
is satisfied when treatment is used to reduce the principal
threats at a site through destruction of toxic contaminants,
irreversible reductions in contaminant mobility, or reductions in
the total volume of contaminated media.
The no-action alternative does not employ treatment as a
principal component of the remedy; toxicity, mobility and volume
of the contamination would remain unchanged.
certain alternatives act to reduce an aspect of toxicity,
mobility and volume (TMV). Although washing structures could
temporarily increase the mobility of contaminants, the diversion
system will direct the wastewater to the evaporation
sedimentation basins. Removal of contaminated dust, demolition
of contaminated structures, and dust suppression activities will
greatly reduce the mobility of the contaminated dust that could
be released into the environment. Decontamination and the
reuse of debris is also a reduction in volume of contaminants at
the site. Treatment of wood by incineration will meet this
standard. Actions to divert surface waters from coming on site
will reduce the potential movement of contaminants in the soils
to Commencement Bay and to groundwater.

-------
The storage alternatives considered for interim action will.
not permanently and significantly reduce toxicity, mObility, and
volume. Because this action does not constitute a final remedy
for this operable unit, the preference for such remedies will be
addressed by the final ROD for this operable unit. Off-site
di~posal will employ treatment where necessary to comply with
land disposal restrictions.
5.
Short-Term Effectiveness
The short-term effectiveness evaluation focused on short term
risks which may occur during construction and remedial action,
until cleanup goals are achieved.

. The alternativE:s. fo:..: dem.olisning and dismantlilly buildings.
and the smelter stack will be effective in safely removing the
existing structures. However, short-term releases of dust and
particulates will result from these activities that will be
effectively controlled. Demolition will include dust suppression
measures to minimize dust emissions to ambient air and to protect
workers. Air monitoring devices will also be used to determine
the air emissions. If air emissions exceed the standard
determined to be acceptable, demolition activities will be
temporarily discontinued or additional measures to reduce
emissions will be undertaken as appropriate.
All the brick storage and disposal alternatives would
present some risk of exposure to workers and residents from
handling and moving the debris which can be minimized by using
health and safety procedures and dust suppression methods. An
"in-situ" containment facility presents some uncertainty of
effectiveness in the near-term, in regard to a potential addition
to surface and groundwater contamination. The fine ore bins
building provides an effective short-term storage facility if the
storage of materials meet waste pile requirements.
The alternative for diverting off-property surface waters
from coming on site will be effective in reducing the transport
of contaminants in surface soils.
6. Implementabilitv
This evaluation addresses the technical and administrativ~
feasibility of implementing the alternatives including the
availability of materials and services required to affect the
remedy.
Explosive demolition, by implosion, of the stack is
considered the only approach which is feasible to implement due

-------
to the height and condition of the stack. The structural
instability of the stack presents technical. and worker safety
problems.
Building demolition and dust suppression appear to. be
technically and administratively implementable because they
employ conventional trade methods. The specific design of the
wastewater collection system, which will involve collection,
treatment and monitoring of wastewater will be completed during
remedial design (RD) but also appears to be technically and
administratively feasible~

Each alternative for.stack brick storage and disposal is.
technically feasible. Ther~ is adequate capacity for on-site
storage in the fine ore bins. Construction of an in-place
storage &rea (i.. e., at the base of the stack) meeting waste pile
specifications can be accomplished.. Adequate off-site disposal
capacity is available.
Of the disposal options, only one alternative, to incinerate
wood in an on-site converter incinerator, is technically feasible
if the converter can be modified to meet emission and performance
requirements.
Decontaminating, reusing and recycling demolition debris are
all techniques which are implementable and will be based on an
EPA-approved sampling plan.
7. Cost
Present worth costs are used to evaluate and compare the
estimated monetary value of each remedial alternative. Present
worth consists of the sum of estimated capital costs and
estimates of discounted annual operation and maintenance (O&M)
costs for each of the following components of the remedy.

Estimated costs for the demolition or dismantling of the
structures other than the stack are $9,192,000, including dust
removal and suppression, surface water containment and diversion,
operation of the evaporator, demolition, and the preparation for
disposal.
The cost of the explosive demolition of the stack is
estimated at $720,500. Other types of manual and mechanical
demolition costs were not gathered, with the exception of
outrigger scaffolding, because these alternatives were not
considered technically feasible. Estimated costs for the
outrigger scaffold are $2,000,000.
Of the containment alternatives for the stack bricks, storage
in the fine ore bins has capital costs estimated at $75,000 to
$260,000. Constructing an in-place storage area would cost

-------
approximately $100,000-$186,562 and.would have higher O&M costs
as a result of long-term groundwater monitoring and maintenance
of the containment features. EPA estimates that disposal of the
stack debris in an off-site landfill would cost from $3,960,000
to $4,996,500; disposal of other demolition debris in an off-
site landfill is estimated to be $22,000,000. This cost could be
reduced depending on the percentage of sa~vageable steel and the
volume of other salvageable and combustible demolition debris
that would not have to go to a landfill. This alternative has no
further costs for O&M. Both on-site storage alternatives are
only temporary and further costs would be necessary to relocate
the bricks into final disposal on or off Site.
. .
Modification of the converter incinerator and operation of
the incinerator, including air monitoring, is estimated to cost
$1,777,COO.
The cost of diverting off-property surface waters to existing
drainage systems of the City of Tacoma and the Town of Ruston is
estimated between $1,869,500 to $2,891,600 based on the
evaluation of costs in the draft Feasibility Study (FS). The
actual costs of diverting the off-property surface water may be
less than these estimated costs since the alternatives in the FS
also included the capital costs of on-site surface water controls
(see Alternatives 3A, 4.1A, and 7A in the Feasibility Study).
The range of estimated costs for the interim remedial action
is from $11,764,500 to $38,686,000.
Modifying criteria
The modifying criteria are used in the final analysis of
remedial alternatives and are generally considered in altering an
otherwise viable alternative rather than deciding between very
different alternatives. The two modifying criteria are state and
community acceptance.
8. State Acceptance
The Washington State Department of Ecology (Ecology) has been
involved with the development and review of the Remedial
Investigation and Feasibility Study for the Site, and with the
development of the Proposed Plan for this interim remedial
action. Ecology favors implementation of the interim measures in
the Selected Remedy to stabilize the site in preparation for
selection of the final remedy in a subsequent ROD and has
submitted a letter of concurrence (see Appendix II).
9. community Acceptance
Many written and oral comments received during the 60-day

-------
public comment period supported implementation of the demolition.
activities. Commentors encouraged EPA.~o approve the plan
rapidly in order to get work underway. Although the majority of
comments supported the plan, some members of the community felt
the stack should be preserved. One commentor specifically
proposed saving the bottom 50 feet as a memorial in recognition
of the history of the site. Additional concern has focused on
the temporary on-site storage component of the remedy.
. Residents and local officials expressed concern that EPA only
store the material temporarily, not permanently dispose of the
materials on site.
IX.
THE SELECTED REMEDY
A.
REMEDIAL OBJECTIVES
The objectives of the selected interim remedial measure are
to:
1.
Remove buildings and structures at the site which are
contaminated and present a hazard, and in anticipation of
the need to further characterize and remediate the Site.
2.
Demolish the increasingly unstable smelter chimney stack to
eliminate the threat of a collapse.
3.
Control the movement of surface water

The selected remedy addresses source areas on site. As
described in section IV, Scope and Role of Response Action, this
operable unit is an integral portion of the overall site remedy.
The interim activities selected in this ROD will contribute to
the efficient performance of the long-term remedial actions under
consideration for the Site. Based on evaluations conducted under
the RIfFS, this interim action operable unit is neither
inconsistent with nor will preclude implementation of the final
remedy.
B.
DESCRIPTION OF REMEDIAL COMPONENTS
EPA selected a plan to address the instability of the smelter
stack, to remove the on-site structures in preparation of final
remediation, and to control off-property surface water run-on at
the Site.

-------
. 1. Site Preparation. s~vera~ measures will be implemented
before beginning the demolition phase of the interim remedial
action.
a.
Asbestos Abatement
Prior to demolition or any other disruptive activities, all
buildings and structures will be inspected to locate and identify
all aSbestos-containing material (ACM). ACM from the on-site
buildings shall be removed and disposed of off site in accordance
with applicable federal and state requirements.
b.
Dust Removal
Buildings and structures at the site (except the stack) will
be vac~11med b€fore beginning demolition activities. Dust remo.~al
will be accomplished by a vacuum Lruck pulling dusts into a
collection chamber using wetting methods at the point of entry.
Dust control methods will be in accordance with applicable
federal and state requirements during the vacuuming procedure.
Areas of structures containing dust that are inaccessible for
vacuuming will be washed down to curtail dust emissions. Dust
washing will include measures to collect waste water, including
concrete slabs, temporary curbing, or sandbags. . Plastic sheeting
may be used if the structure is not located on a concrete slab.
Wastewaters generated from the dust suppression system will be
collected at each demolition site and routed to a wastewater
evaporation system.
c.
Road and Tunnel Survey
In response to comments, roads used for the transport of
stack brick and for the transport of demolition debris off Site,
will be surveyed before relocation of the debris commences. A
rail and car tunnel survey will be completed before and after
demolishing the smelter stack to confirm that no structural
damage was caused by the impact of falling brick. .
Transport of the debris from demolished Site structures,
other than the stack, to the fine ore bins will not use Ruston
roadways or the tunnel."
2.
Demolition of structures
a.
Buildings and structures other than the Stack
Demolition of, or dismantling of the on-site structures will
be accomplished by conventional trade demolition techniques.
Approximately 73 structures listed on Appendix V to this ROD, as
well as miscellaneous sheds, warehouses, tanks, bins and
trestles, will be demolished or dismantled. Conventional

-------
equipment, such as shears, grapples, loaders, and cranes, will b~
used where necessary to safely and efficiently dismantle ~he
structures. To the best of EPA's knowledge there are no
underground storage tanks at the Asarco facility as represented
in the RIfFS.
High-pressure water fogging nozzles will be used to minimize
dust emissions to the maximum extent possible during demolition.
During demolition, surfaces newly exposed will be immediately
wetted to control dust. The evaporation system, as described in
Appendix A to the Asarco site Stabilization Plan Phase II, will
be designed to evaporate the water from solids. The solids will
be collected and stored in "the fine ore bins building or sent off
Site for recycling. :.
b.
Smelter Stack
The smelter stack will be demolished by a controlled
explosive demolition technique known as implosion. The implosion
will be designed so that the stack debris will collapse into a
confined area in which a trench will be constructed to
temporarily contain the stack bricks before moving the debris
into the fine ore bins building.
A number of precautionary and safety measures are included in
the remedy. A dust suppression system will be installed around
the stack that is designed to prevent, to the maximum extent
practicable, the release of dust and particulates during the
demolition. If practicable, and if determined necessary to
suppress dust, an encapsulant will be applied to the interior
lining of the stack prior to the demolition. Seismograph and air
blast meters will be installed to record ground vibration and air
pressure generated by the explosive demolition. Residents living
within 1,000 feet of the stack, which includes approximately 35
residences, will be asked to evacuate during the period of stack
demolition. Evacuation procedures will be conducted with local
officials. The demolition and monitoring of the demolition will
be conducted in conformance with applicable federal and state
occupational safety and health requirements, and will consider
guidelines by the u.S. Bureau of Mines that pertain to open
blasting.

The trench into which the stack debris will fall will be
constructed to prevent any dust suppression wastewater from
penetrating the underlying soils and ground water. The sides of
the trench will be bermed with soils from the smelter stack area.
A french drain system will cover the bottom of the trench. This
drainage area will be covered with visqueen to prevent water
penetration and a sufficient cover of sand to protect the
visqueen from penetration by the stack bricks.

-------
c.
Surface water controls.
During the demolition activities new surface soils will be
exposed, and demolition debris will be temporarily stockpiled
around the site before moving it to the fine ore bins building.
precipitation contacting the demolition area and water generated
from the demolition activities will come in contact with the
exposed surfaces of the demolition debris, and exposed soils.
There is a potential that the water may pick up contaminants and
transport them off Site. Soil containment and surface water
control measures will be ~mplemented to minimize the potential
for soil erosion and contaminant transport. The control measures
include the following:
- Soil cover/traps
- Soil ~ealant/bi.1ders
- Surfat,;e water diversion ditches
- Soil berms/containment structures
- Grouting key drains to re-route potentially contaminated
surface water to the water evaporation system
- Routing collected surface water to the evaporation
system
As the demolition process takes place each of these measures
will be considered on an area specific basis and the best measure
or combination of measures will be implemented. Surface water
discharge points from the site will be monitored to ensure that
outfall to Commencement Bay does not exceed discharge limits
established by EPA and the State.
d.
Air Monitoring
To ensure that these interim activities comply with federal
and state air quality requirements, and to evaluate their impact
on air quality, an ambient air monitoring program using high
volume samplers to test for metal particulates and air sampling
equipment for semi-volatile compounds, will be implemented during
site preparation work and all demolition and dismantling
activities. Action levels will be determined based on ARARs
under the Clean Air Act for specific contaminants, and other
health risk based factors.
3.
Disposal of materials from demolition activities
Demolition debris and materials from the Site will be
disposed of in several ways, depending on the type of material
and nature of contamination. The appropriate disposal option
will be approved by EPA after approved protocols for sampling and
analysis are used to assess the level of residual contamination
and the potential for decontamination of the material. As
demolition debris is generated, it will either be stored on site
in the fine ore bins building until a final disposal remedy is

-------
selected "or disposed in an off-site di~posal site approved by
EPA. Non-or de-contaminated debris can be reused or recycled.
a.
Temporary On-site Disposal In Fine Ore Bins Building
The fine ore bins, an enclosed concrete building with a roof
within the area of contamination, will be used for the temporary
storage of demolition debris to prevent the release of hazardous
and dangerous wastes into the environment. The storage of
demolition debris will meet the waste pile requirements of
hazardous waste facilities (see footnote 5 below). All forms of
demolition debris from buildings and the stack may be stored in
the fine ore bins building 'pending selection of a permanent
disposal remedy in the fina~; ROD for this site. Prior to storage
in the fine ore bins, the materials will undergo a waste analysis
to identify the type and level of contamination. .

The stack bricks will be loaded into trucks from the trenched
area and taken to the fine ore bins building. Hauling the stack
debris will require travel on public roadways, and require
decontamination of haul trucks at the loading/unloading areas.
Concrete, steel, wood, or other types of debris that cannot
be decontaminated for reuse or recycled, or; in the case of wood,
which cannot be incinerated, will be stored so that the materials
may be segregated by type of material or contamination.
b.
On-site Incineration
Wood materials will be sampled to determine if they are
dangerous or hazardous wastes. Wood which is not a hazardous or
a dangerous waste will be incinerated on site in a modified
production vessel called a converter. Materials that are
considered hazardous or dangerous waste will not be burned in the
incinerator, which is not designed to comply with the hazardous
waste incinerator requirements. The volume of wood is expected
to be 10,500 cubic yards. If the incinerator cannot meet
emission requirements, the wood debris will be either shipped off
site for disposal or stored on site in the upgraded fine ore bins
building pending selection of the final remedy.
c.
Off-site Disposal
(1) Demolition debris can be shipped off site for
disposal in an appropriate facility, depending on the nature of
contamination. All material will undergo a waste analysis prior
to shipment off Site. All off-site disposal facilities must be
operating in compliance with applicable federal or state laws and
EPA's" off-site disposal policy before the material is shipped.
Hazardous waste bound for off-site disposal must be disposed ~n a
hazardous waste disposal facility. Dangerous waste will be
evaluated to" determine whether it is also a hazardous waste
34

-------
before shipment to identify th~ typ~ of facility that is
appropriate. Asbestos-containing materials will be disposed. at a
facility operating in accordance with federal NESHAPs regulations
and applicable state law. Waste materials that are only solid
waste (not hazardous or dangerous) may be shipped off Site for
disposal at a solid waste facility. All packaging, manifesting,
and shipping of materials will comply with applicable federal
Resource Conservation and Recovery Act (RCRA) and Department of
Transportation (DOT) regulations for hazardous wastes and
hazardous materials, and with state requirements. .

(2) A number of materials at the site may be
adequately decontaminated,'if necessary, and then reused or
recycled. Steel and wood meeting decontamination requirements
can be salvaged for reuse. Materials such as steel may be
~econtaninated on Site al&d then shippee. to an off-site facility
to be recycled by batch m~lting or resmelting~ ~~he ledd and
residuals collected in dust and wastewater sludge may also be
shipped to an off-site facility to be recycled.
4.
Drainage Control
Surface water from areas adjacent to the Site will be
diverted to prevent it from entering the site before demolition
activities begin. In general, based on a conceptual design
described in the Feasibility Study for final Site cleanup,
diversion ditches and conduits will be used to ensure proper
drainage of storm water from the surrounding areas and prevent
the surface water from entering the Asarco facility. Surface
water will be diverted to storm water outfalls that discharge to
Commencement Bay, and the discharge will be monitored to
determine whether it meets water quality standards. If the
discharge exceeds water quality standards, the surface water will
be evaluated to determine whether additional best management
practices should be implemented or if treatment is necessary
prior to discharge. The evaluation of additional controls will
consider, among other things, AKARTs, water quality standards,
background levels in area storm water and the quality of
receiving waters.
x.
STATUTORY DETERMINATIONS
EPA's primary responsibility under its CERCLA authorities is
to ensure that remedial actions at Superfund sites are protective
of human health and the environment. In addition, section 121 of
CERCLA establishes several other statutory requirements and
preferences. These specify that when complete, final remedial
actions must comply with applicable or relevant and appropriate
environmental standards unless a statutory waiver is justified.
The selected remedy must also be cost-effective and utilize
permanent solutions and alternative treatment technologies or
35

-------
resource-recovery technologies to the maximum extent practicable:
Finaily, the statute includes a preference for remedies that
employ treatment that permanently and significantly reduce the
volume, toxicity, or mobility of hazardous wastes as their
principal element.
The interim action operable unit remedy selected for the
Asarco Smelter superfund Site is consistent with statutory
requirements of section 121 of CERCLA and, to the extent
practicable, the National contingency Plan. This interim action
operable unit is not inconsistent with nor will it preclude
implementation of alternatives being considered for the final
remedy for the site.
A.
Protection of Human Health and the Environment
-.
The selected interim remedy will protect humanh~alth and_the
environment by demolishing and dismantling structures at the
Site, and temporarily storing the demolition debris on Site, in a
safe and protective manner pending selection of a final remedy
for this operable unit. .

The interim remedial action will be protective by removing
the threat of an uncontrolled collapse of the smelter stack,
resulting in releases of hazardous substances and in the danger
from falling debris. Studies performed for the RI/FS at the site
indicate that the stack is unstable and poses the potential of
collapse. The remedial alternative selected calls for stack
demolition in a manner planned to be protective of workers and
nearby residents. In addition, this interim remedy will remove
most of the buildings and structures on the site so that
evaluation of the nature and extent of contamination at the Site
can be completed in preparation for the final remedial action.
The selected demolition activities will be implemented in a
manner that is protective of human health and the environment.
Removal of the stack with explosive charges may result in some
potential for air emissions and short-term risk. Engineering
controls that are part of the remedy will be implemented to
suppress emissions of dust and contaminants into the air due to
demolition activities. It is expected that the magnitude of
these risks and specific control methods will be evaluated in
greater detail during the remedial design.
Extensive health and safety plans will be prepared to ensure
the safety of and minimize exposures to the residents of the
surrounding neighborhoods and on-site workers, and to mitigate
releases to the environment, to the maximum extent practicable.
Workers will follow strict guidelines meeting federal and state
occupational safety and health standards to safeguard against
36

-------
demolition accidents and from .expos~re to airborne contaminants.3

Residents within 1,000 feet of the smelter stack will be
evacuated, if they choose, during stack demolition to prevent any
exposure .to airborne contaminants and debris. Air sampling and
analysis will be conducted during remedial activities to monitor
air quality and ensure that the measures are effective. Surface
water control measures will be implemented to collect, to the
extent practicable, contaminated water generated by dust
suppression methods to prevent releases to Commencement Bay and
the environment.
Similar protective measures will be implemented during the
dismantling and demolition of buildings on the Site. Throughout
the remedial action, acticns to control surface water movement
will iJe taken, as ~.echnic.llly feasibl'3, during and after the
demolition to prevent the migr;:ltivn cf.f Site of contaminated
demolition debris and surface soils. Any structures that are not
demolished or dismantled will be sampled and decontaminated as
necessary to ensure their continued presence does not pose
unacceptable risks pending selection and implementation of the
final remedy for the smelter site.
Materials generated by the demolition and dismantling actions
will be stored in the fine ore bins building on site in a manner
that will prevent the release of hazardous and dangerous wastes
into the environment. Some materials from the demolition and
dismantling activities may be transported from the Site for off
site use or disposal. Materials that are not hazardous or
dangerous wastes, or that can be decontaminated, may be salvaged
for reuse. Decontamination procedures will be followed to ensure
the materials are not hazardous or dangerous. The need for
decontamination and the effectiveness of the decontamination
procedures will be verified by sampling and analysis before final
disposition.
3Regulations under OSHA apply to the conduct of the remedial
action as it involves workers at the Site. During implementation
of response actions, control measures will ensure that worker
exposures do not exceed any threshold limit values established for
substances at the site. Training of on-site workers will meet the
requirements specified in 29 CFR 1910.120. Remedial activities
will employ the specified type of safety equipment and procedures.
Demolition activities will be conducted in conformance with Subpart
T of 29 CFR 1910 (Demolition) and explosive demolition of the stack
will comply with Subpart U of 29 CFR 1910 (Blasting and Use of
Explosives) . The remedial activities will also comply with
applicable state occupational safety and health requirements.
37

-------
storm' water from areas near the site will be diverted away
from the site to reduce the transport of contaminants from on-
site surface soils to Commencement Bay and to ground water.
B. ComDliance with ADDlicable or Relevant and ADDroDriate
Reauirements
The selected interim remedial action will meet or attain all
federal and more stringent state applicable or relevant and
appropriate requirements (ARARs) that have been identified. No
waiver of any ARAR is being sought or invoked for any component
of the interim remedy. No. ARARs for cleanup of groundwater,
soil, or slag are included-in this analysis, but will be
evaluated as part of the final remedy for this site. The laws
and regulations of concern that are action-, chemical-, and
location-specific include: .

state Dangerous Waste Regulations, WAC 173-303.
RCRA, as amended, and implementing federal regulations create
a federal program for managing solid and hazardous wastes.
Washington state has also enacted legislation and implementing
regulations that address the management of solid, hazardous, and
dangerous wastes. Responsibility for implementing most of the
federal requirements have been delegated to the state program, so
state dangerous waste regulations generally will be the ARARs for
this remedial action.
Materials from the demolition or dismantlement of structures
will be analyzed to determine whether they are a hazardous waste,
including whether they exhibit the toxicity characteristic
leachate procedure (TCLP) characteristic of a RCRA hazardous
waste. In addition, materials will be analyzed to determine
whether they are dangerous wastes under state requirements. Some
wastes containing greater than 100 ppm arsenic are currently
regulated as dangerous wastes by washington.4 Materials that
meet the definitions of hazardous waste (federal) or dangerous
waste (state) that are generated by the demolition and
dismantling of site structures and remain on site will be

state hazardous waste storage requirements for waste piles.s
Specifically, the waste pile regulations at WAC 173-303-660
provide that a waste pile may be located inside or under a
structure that provides protection from precipitation so that
neither run-off nor leachate is generated, provided that liquids
or materials containing free liquids are not placed in the pile
and other specified conditions are met. The federal and state
h~zardous waste regulations also specify facility management
practices that will establish operating procedures for the site
during storage of the wastes.

Federal and state land disposal restrictions (LDR) will not
apply to the consolidation qf waste within the same area of

converter. EPA can authorize Asarco to conduct a remedial action
to fully comply with this permit under the authority of CERCLA
~122 (e) (6). In the event EPA determines, however, that it is
necessary to withdraw its authorization, any activity involving
the converter must comply with substantive requirements under
federal or state laws and regulations including those for
emissions of particulates, arsenic, sulfur dioxide, hydrogen
chloride and disposal of incinerator ash. Wood that is

by all known available, and reasonable technology (AKART) if the
contaminant levels exceed permitted levels which are generally
water quality standards. For storm water discharges, the state
considers Best Management Practices (BMP) to constitute AKARTs.
Source control BMPs include measures to prevent the storm water
from being contaminated in the first place.
Surface water, composed of storm water runoff coming from
areas near the Site will be diverted so that it no longer crosses
the site. The surface water will be diverted from contaminated
surfaces at the Site, thus using BMP to meet AKARTs. The
diverted water will be monitored at the point of discharge from
the point source created by the surface water diversion to
determine compliance with water quality standards.
During the demolition activities, control measures will be
taken to minimize surface water contact with contaminated soils
and demolition debris that could be discharged to surface waters
off site. Precipitation from the demolition area and water
generated from the demolition activities will be collected and
routed through an EPA-approved evaporator system. Surface water
discharge points from the site will be monitored to ensure that
discharges to Commencement Bay do not exceed the substantive
discharge limits established by the NPDES Permit Program which
will reduce further contaminant loading in the Bay.

at the site, EPA will determine whether the site is eligible for
the NRHP and will consider data recovery as a miti~ation measure
if appropriate.

regulations by the Office of Surface Mining at 30 CFR ~ 816.67.
These documents and regulations, which apply to blasting during
mining activities, will be considered in designing and monitoring
explosive demolition of the stack.
C.
Cost-Effectiveness
The selected interim remedial action is cost-effective
because it is protective of human health and the environment,
attains ARARs and achieves an appropriate balance of long-term
effectiveness and permanence, the reduction of toxicity,
mobility, or volume and short-term effectiveness; i.e., the costs
of the remedy are proportional to its overall effectiveness.
The cost of demolishing and dismantling buildings and
structures other than the stack by conventional methods is
estimated to cost $9,192,000, including the cost of sampling and
analysis of materials for disposal or reuse, and environmental
monitoring during demolition operations. Demolition of the
stack, including environmental monitoring, is estimated to cost
$720,500.
Cost estimates for disposal of materials generated by the
demolition activities vary depending on the choice of disposal
method. The cost of modifying the on-site incinerator to meet
air pollution control requirements and to incinerate wood debris

-------
is estimated at $1,777,000. The effectiveness of permanent
disposal of the wood debris by on-site incineration is
proportional to its costs. Wood and other materials from the
site can be decontaminated and may be salvaged for reuse. The
non-wood-debris that is not salvaged will be stored temporarily
on-site in the fine ore bins building. Asarco estimates the cost
of transporting and storage of debris from the stack demolition
in the fine ore bins at $260,000. Pending the selection of a
final remedy for disposal of the demolition wastes, the temporary
storage on site in the fine ore bins building is cost-effective.

The cost of diverting off-property surface waters to existing
drainage systems of the City of Tacoma and the Town of Ruston is
estimated to be up to $2,891,600, but may actually be lower.
Implementation of these measures would be protective of human
health and the environment. The estimated total cost of
implementing thes~ measures ranges from $11,764,500 to
$38,68b,000.
D. utilization of Permanent Solutions and Alternative
Treatment Technoloqies (or Resource Recoverv Technoloqies)
to the Maximum Extent Practicable
The selected interim remedial action to demolish structures
at the Site does not provide permanent solutions to all
contamination problems at the site. However, there are several
features of this selected remedy that provide a permanent
solution. The primary purpose of this ROD is to start and safely
clear structures from the site in anticipation of the permanent
remedial action that will be subsequently selected. EPA has
determined that the interim remedial action selected in this ROD
is not inconsistent with nor will it preclude implementation of
the final remedy.
While the selected remedy is an interim measure, the remedy
employs permanent solutions in several ways. Demolition of the
stack will permanently eliminate the threat of an uncontrolled
collapse. The remedy will permanently remove most structures on
the site, which will enable the Agency to plan the final remedy.
In addition, this remedy provides for final disposition of many
materials from the Site, to include salvaging reusable materials
and incinerating most of the wood debris that is not a hazardous
or dangerous waste. The remaining debris will be stored on site
until selection of a final disposal remedy in a subsequent ROD.
E.
Preference for Treatment as a Principal Element
Demolition and temporary storage on site provides an interim
solution to contamination problems at the site pending selection
of a final, permanent remedy. Because this action does not
constitute the final remedy for this operable unit, the statutory

-------
preference for remedies that employ treatment that reduces
toxicity, mobility, or volume as a principal element will be
addressed by the final decision document for this Site.
Subsequent actions are planned to address fully the principal
threats posed by this site.

ASARCO INTERIM REMEDIAL ACTION RESPONSIVENESS SUMMARY
I.
Overview
The Asarco Tacoma ~melter site (the Site) is part of the
CommencelUent Bay NearshorelTideflats (CB NIT) Superfund Site, which
was listed on the interim priority list by the Environmental
Protection Agency (EPA) in 1981 and included in the first
promulgated National Priorities List that EPA published in
September 1983. The Asarco Tacoma Smelter Site, in Ruston and
Tacoma, . Washington, is located on approximately 67 acres of
property owned by ASARCO ::Incorporated (Asarco). A Remedial
Investigation and Feasibility Study (RI/7S) are underway for the
entire facility. This responsj ...ene-ss s"~~ry add~esses puQlic
co~~ents mad~ rcgarGi~g ~ pr~posed Interim R~mecial A~tio~ at the
facility.
This Interim Remedial Action calls for activities to
demolish contaminated structures to clear the Site for the
completion of the RIIFS, prevent the threat of an uncontrolled
smelter stack collapse, and control the movement of off-site
surface water onto the Site.
. The facility began operation in 1890 as a lead smelter
under the ownership of the Tacoma Smelter Company. Over seventy
buildings and the smelter stack, which is 562 feet high, were
constructed between 1902-1917 for copper smelting and the
refinement of process byproducts. During the period of copper
smelting operation, Asarco generated large quantities of copper
reverberatory slag (slag). Historically, molten slag was poured
on the ground and at the shoreline edge as fill material, which
altered the shape of the original shoreline. The Site area also
includes a pond that was used during plant operations as a
discharge point for cooling water. Since the early 1970s, the
pond, which is at a low elevation, has served as a natural drainage
basin on the site and receives runoff from about 45 acres off site
of Asarco property.
Since the late 1960' s the Puget Sound Air Pollution
Control Authority (PSAPCA) has been regulating sulfur dioxide and
arsenic emissions from the smelter, although Asarco was granted
variances until 1975. EPA requirements for National Pollution
Discharge Elimination Systems (NPDES) permits regulating point
source water discharges were also applied in 1975.
After the facility ceased arsenic smelting operations in
January 1986, Asarco signed a legal agreement called an
Administrative Order on Consent (AOC) , in September 1986 with
Asarco agreeing to investigate the nature and extent of the
contamination problems at the facility and develop alternatives

-------
for cleanup where necessary.
ongoing as mentioned above.
Th~s work is called an RIfFS and is
As part of the Consent Order a Site Stabilization Plan
Phase I -( SSP) was developed and agreed upon to remove the most
contaminated structures on the site involving arsenic production
and arsenic contaminated emission control. Demolition activities
started in July 1987 and were completed in 1988.
Asarco has also been working to determine the extent of
contamination at the facility and evaluate alternatives for cleanup
in accordance with the 1986 Consent Order as described above.
Although progress has been made toward gathering information in
order to fully cleanup th~ Site, EPA believes that additional
sampling must take place and a more detailed evaluation of
tre3tment altern~tiv~s must be pe~for.med before any firial decision
can be made. -' -
In the meantime, EPA believes that important progress
could be made toward final Site cleanup by taking steps to begin
the second phase of demolition -activities at the site. This will
allow the initial steps of cleanup to get underway while the
additional information about the extent of contamination is being
gathered. Removing the Site buildings will also allow for better
characterization of the contamination on the Site as the soil
beneath the buildings also needs to be sampled. Since the
demolition is estimated to take two years, EPA decided to go
forward and proposed this plan of a two-phased cleanup to the
public.
The EPA held a 60-day public comment period from July 18,
1990 to September 18, 1990 to provide an opportunity for interested
parties to comment on the July 16, 1990 Proposed Plan for interim
actions for demolition of structures on the Asarco Site. This
interim operable unit includes:
the removal of buildings at the site which are
contaminated and present a hazard and in anticipation of
the need to further characterize and remediate soil, fill
materials, and groundwater at the site:
the control of surface water from adjacent areas coming
on site to reduce the amount of water running through
contaminated soil and to minimize the transport of
contaminants to groundwater and off site.
EPA held a public meeting the evening of August 16, 1990,
at the Bates Vocational Technical School Ruston Campus in Ruston,
Washi~gton to outline EPA's proposed demolition activities, answer
questions and take public comment.

-------
The meeting was attended by approximately sixtY-five
people including EPA and Asarcb representatives. Although many of
the questions asked pertained to the proposed demolition
activities, questions were also raised about the Ruston Expedited
Response. Action (ERA) sites and other Asarco off-property
Ruston/North Tacoma issues. Several letters were received from
concerned citizens and local governments. All of the questions and
comments received during the public comment period are addressed
in this Responsiveness Summary.
Representatives of the State Department of Ecology have
reviewed the EPA Record Of Decision and have concurred with the
EPA Selected Remedy. "

The Asarco Tacoma Smelter has been the subject of much
interest and concern amongst the communities of Ruston and North
Tacoma, Washington for many years. This summary is specific to
communi ty interest and involvement since the Superfund process
began at the site in 1986, when Asarco began its first phase of
site stabilization (demolition). The following summarizes concerns
about all of the Asarco related proj ects but it focuses on
community involvement in the demolition activities described in the
Interim Record of Decision for the Asarco smelter. EPA is aware
that the concerns have changed over time and that.this summary may
not reflect all interests, but does attempt to. describe community
involvement in the Superfund process at Asarco.
Since work to characterize the contamination at the
Asarco smelter began, EPA has been working to keep the local
communi ty informed and involved in the progress of the
investigation. Many residents in the area are aware of the
smelter's history and have relatives who worked at the smelter or
may have worked there themselves. Historically, members of the
community have been concerned that the contamination at the smelter
site be properly contained, removed or cleaned up completely so
that the property can be returned to profitable economic use to
provide revenue to support the Town of Ruston. More recently there
has been interest expressed (initially by the City Club of Tacoma)
that the smelter property be developed into a park after the clean
up is complete.
Probably the most common and frequently expressed concern
is that Asarco not be allowed to construct a hazardous waste
containment facility on the property. .Many members of the
community, including local officials, have expressed their concern
with such a proposal in that it would compound the stigma they feel
exists in the Tacoma area. People feel the Tacoma area has had an
unfair label of a contaminated place and that an on- site hazardous
waste containment facility would only enhance this image. The Town

-------
of Ruston has taken additional steps apd passed a local ordinance
prohibiting such a facility. .
There are also concerns amongst members of the community
about EPA' s acti vi ties adj acent to the smelter property in the
surrounding residential area. The residential area is the subject
of a separate investigation and study of cleanup alternatives.
Some cleanup work is also nearly complete in the residential area.
This work has been known as the "Expedited Response Action" and
involved scraping the top layer of soil from 11 publicly accessible
sites and replacing it wit~ clean fill and a grass or gravel cover.

Work to conduct the Expedited Response Action began in
1988. EPA held a public cOmment period in the Fall of 1988 during
which the agency received significant comments from the public
questioning the proj ect', s impact on area property values and
whether arsenic in area soils really presents a health risk.
Another of the concerns expressed during public comment was that
EPA had not done a good job of involving the community in its
efforts to clean up the 11 sites. EPA believes that public
involvement in the Superfund process, especially at a Site which
impacts so many people, is very important. As a result of the
pUblic's interest in becoming more involved, EPA took steps to
reach more people before beginning its investigation of the entire
residential area. Although these activities were initiated' in
preparation for the off-site investigation, they have become
valuable means for the community to be involved in all of the
Asarco related projects. ' '
First, EPA expanded its mailing list to include more
members of' the community. EPA sends fact sheets describing the
Agency's progress on the Asarco related projects as a baseline of
information. A list of fact sheets that have been sent out to date
can be found in Attachment A. In the interest of promoting better
information exchange between EPA and the community, members of the
community also requested that an EPA staff member be available in
the community a few days a' week to answer questions and hear
concerns. In response to this request, EPA hired a community
liaison who now has an office in Ruston and is available to speak
with individuals or address interested groups. This has been a
posi ti ve step in promoting better communication and an
understanding of community concerns.
Al though the fact sheets are an important means of
reporting progress and members of the community find them useful,
EPA and the community felt that more involvement in addition to
information was needed. In October 1989, a community workgroup
was formed, again primarily to promote involvement in the
residential investigation. However, the group is interested in
all aspects of the Asarco cleanup and has provided EPA with useful
feedback on its activities for the smelter site. EPA first
solicited interest in the group in June 1989 in a fact sheet that

-------
t
was mailed to 5,000 addresses in the Ruston and North Tacoma area.
The workgroup now has 17 members who regUlarly attend the monthly
meetings; however the meetings are open to any interested resident.
. . One workgroup meeting (July 1990) focused specifically
on the proposed plan for demolition. The workgroup provided.
important feedback as to additional pieces of information that they
wanted to see in the proposed plan. EPA was able to incorporate
all of the group's sugge~tions before releasing the proposed plan
for public comment on July 16, 1990. The plan was subject to
public comment for 60 days and was also discussed at a public
meeting on August 16, 199'0. All of the comments received during
the period, EPA's responses to them and changes made to the plan
based on those comments are ~;described in the following section of
this responslveness summary.
III. Summary of Comments Keceived During the Public Comment Period
and EPA Responses

This responsiveness summary addresses the comments received
by EPA concerning the Proposed Plan for the Interim Measures at
the Asarco Smelter site. Approximately twenty written comments
were received in ten letters and twenty-five oral comments were
presented by citizens at the August 16, 1990 public hearing.
Several of the written and oral comments addressed similar concerns
and have been organized accordingly. Comments and questions raised
during the public comment period are summarized below and are
grouped by category.
Copies of the transcript for the meeting are available at all
the public repositories listed in the Community Relations section
of the Record of Decision (ROD) and a copy is part of the
Administrative Record (AR). Copies of the letters received have
been included in the AR.
RESPONSIVENESS SUMMARY
Demolition
1.
Comment:
A few commentors expressed the opinion that the
stack ought to be saved. Suggestions included:
encasing in concrete, plugging it, painting it so
it could be used as a tourist attraction or install
elevators to convert the stack into an observation
point for Commencement Bay; or saving the lower 50
feet as a monument to the area's historical past.
Response: As identified in the Remedial Investigation (RI)
and the site Stabilization Plan Phase II, the smelter stack is

-------
)
not stable. The significant ~epair~ that would be necessary to
save the entire stack are not practicable due to the stack's
deterioration over the years and its height. Asarco's
engineering consultants believe that to save the base,
explosives would need to be placed above the base of the stack
which would reduce control over where the stack would fall.
2.
One commentor expressed concern that the plastic,
which will line the bottom of the bermed trench
the stack bricks will fall into, will be punctured
by falling bricks.

Response: The purpose of lining the trench with plastic
during the demolition ::process is to prevent potentially
contaminated water used' to suppress dust resulting from the
demolition of the stack from being absorbed into the soi.l. Any'
. water collected will be routed to the existing wastewater
evaporation system on site.
Comment:
In response to thecommentor's suggestion an adequate
engineering design, i.e. using layers of sand as a cushion
above and below the plastic, will be used to minimize the risk
that this plastic will be punctured by falling bricks. Under
the bermed area a french drain, or underground confined gravel
and a buried channel, will be used to contain and direct
wastewater collected during stack demolition.
3.. Comment:
One commentor asked how deep the smelter stack base
went underground..
Response: Asarco asserts the base of the stack extends thirty
feet under the surface.
4.
Comment:
A demolition contracting company submitted a
detailed evaluation of the demolition technique to
implode the stack as outlined in the site
stabilization plan. They have several technical
concerns regarding the implosion of the stack, the
types and placement of explosives, and the design
of the trench the stack bricks would fall into.
Response: The detailed evaluation submitted by the demolition
company concludes that the stack can be demolished in a safe and
protective manner. The concerns described in the report will be
addressed and resolved during the Remedial Design/Remedial Action
(RD/RA) phase of the Interim Action for Demolition of On Site
structures.
5.
Comment:
One nearby resident was concerned that imploding
the stack would harm the structure of his home.
Response:
Based on EPA' s experience in other regions with

-------
similar activities, EPA does not anticipate that the ground
vibration or air blast caused -by demolition techniques will
adversely affect the nearby homes. However, the selected remedy
calls for geophysical monitoring during blasting to determine
its effects. EPA's opinion is that Asarco would be responsible
for adverse affects, if any, resulting from the demolition.
Several commentors expressed concern that stack
demolition would harm the structural integrity of
the car and railroad tunnels. They asked whether
EPA or Burlington Northern Railroad would be
checking these tunnels.

Response: In response ~;to this comment EPA will require that
structural engineers go into th~ tunnels before and after the
stack has I~.:>me dO\'!11 to :%lakE" sU-:-P t~at the tunnels are so\,'nd.
Details for such inspections will be c'-'mpl2t9d prior to stack
demolition.
6.
Comment:
7.
Comment:
The Town of Ruston requested that a road survey be
completed before demolition activities begin to
determine present road conditions and evaluate the
impact of the demolition activities on local
traffic. The Town also requests that alternate
routes of transportation or alternative modes of
transportation, ie. rail or water, be considered
if many vehicles are entering and exiting the site.
Response: In response to the Town's request a "before and
after"survey will. be conducted the use of roads that are used
to move debris materials from the stack area to the fine ore
bins building and any other routes that will be used to take
materials off Site.
Alternative modes of transportation will be evaluated in the
design phase of planning.
8.
Comment:
One commentor suggested that the roadway tunnel on
Ruston Way be removed as a part of the demolition
efforts.
Response: A project concerning the removal of the tunnel is
beyond the scope of the present interim action. There is no
evidence that removal of the tunnel is necessary to be
protective of human health and the environment. If during the
design of plans for the interim actions or in selecting the
final remedy for the site a need to remove the tunnels is
indicated, then EPA will evaluate and consider the alternatives.

-------
9.
Comment:
Several commento~s thought. that the demolition
project and the proposed Ruston Way roadway
realignment project could be accomplished
simultaneously.
Response: Because the roadway runs across contaminated areas
of the Site, it is unlikely that plans can be made for
construction of a roadway until a remedy for the full Site
cleanup has been chosen. However, when the Town develops
preliminary plans for realignment, EPA will discuss how those
plans may be incorporated into the on-going site actions. EPA
hopes that future roadway plans will be available before
implementing a final .Site cleanup remedy so they can be
integrated into the final cleanup plans.
10. Comment:
A ~ew commentors were. concerned. that the Asarco
property. would remain an "eyesore" after demolition
and wanted EPA to enhance the aesthetics of the
property.
Response: Footings and concrete pads will be left in place
until the final cleanup measures begin; and debris will be
securely stored. The final condition of the Site will be
determined during selection and implementation of the permanent
remedy.

Disposal- The following category is further broken down into two
subsections: "Temporary Storage" and "Converter."
1.
Comment:
One commentor reminded EPA that the Town of Ruston
has a local ordinance prohibiting the disposal of
hazardous waste within the Town limits. The City
of Tacoma's Environmental Commission, the City of
Tacoma, and the Town of Ruston are opposed to a
permanent disposal site for demolition debris on
Asarco's property. Their concern is that federally
. regulated hazardous waste will be stored
indefinitely on this site.
Response: EPA understands that the community of Ruston is
concerned about the long-term storage, or disposal, of hazardous
or dangerous materials within the Town limits. At this time EPA
is planning only temporary storage for the demolition debris
over the next several years. Although local ordinances and
requirements generally are not binding on EPA cleanup
activities, the local ordinance will be considered and evaluated
as EPA reviews the alternatives for the final on-site cleanup.

-------
Disposal/Temporarv Storaqe: .
1. Comment: One public official "asked about the length of time
that the demolition debris would be stored at the
Asarco site.
Response: Materials that cannot be cleaned, salvaged or
burned, will be stored under cover in the fine ore bins 1tntil
EPA selects a final cleanup remedy fur the entire site. Full
site cle~nup is expected to take about five years, once a final
decision is made. .
2.
Comment:
Several cbmmentors wondered about the extent of
contamination in the concrete, wood, steel and
other materials generated by the demolition and
dismantling.process, and where this debris would
be disposed or stor.ed.
Response: In general, EPA expects that some of the demolition
debris will be contaminated with metals and organic compounds
as a result of the nature of work carried out at this facility.
Some of the materials can be cleaned to safe levels. Several
alternatives for disposing, temporarily storing and reusing or
recycling the demolition debris are detailed in the Selected
Remedy, section IX of the ROD. The appropriate disposal option
will be determined during implementation of the interim remedy
as the materials are tested for contaminant levels.
3.
Comment:
The Town of Ruston opposes the use of the fine ore
bins for temporary storage of demolition debris as
this may negatively affect the project and funding
for realignment of Ruston Way.
Response: Because the proposed roadway runs across
contaminated areas of the Site, EPA expects that siting or
constructing the Ruston Way realignment project cannot be done
until the final cleanup strategy for the facility has been
completed. Planning the new roadway can begin now with dialogue
between the Town of Ruston, Asarco and EPA. (See response for
Demolition, question 10.) The temporary storage of any
materials in the fine ore bins building will not hinder future
efforts of roadway realignment because EPA expects that all
demolition debris will be moved out of the fine ore bins
building upon implementation of a final remedy.
4.
Comment:
The City of Tacoma is concerned that an on-site
containment facility (OCF) is being considered in
the final remediation plans for the Asarco
property. They feel that the siting of an OCF is
in direct confl ict to the City's long-term programs
and interests.

-------
Response: EPA has not yet .decid~d on. the full-site cleanup
plan, including whether EPA will approve construction and use
of an on-site containment facility at the smelter. EPA has
required Asarco to evaluate a full range of alternatives for
full site cleanup. The alternatives range from no action to a
variety of treatment and containment options. At this time an
OCF is a part of several of the alternati~e cleanup solutions
discussed in the Feasibility study (FS). This disposal option
will be evaluated using the nine criteria as required by the
National contingency Plan (NCP), see ROD page 21, to choose the
most protective, implementable, and cost-effective remedy for
the long-term storage 'of demolition debris.
"
5.
The Town of Ruston, concerned that the double
handling of' demolition debris from the smelter
stack would in~rease response costs .a~d increase'
the risk of exposure to . contaminated. dust,
suggested the debris be capped and landscaped where
it lay following the stack demolition.

Response: In the Selected Remedy EPA has selected the fine
ore bins for temporary storage of structure and stack brick
debris. Creating a waste pile of the stack bricks in place
after demolition would require extensive Site preparation work
and would cover a part of the Site with debris. Final decisions
concerning the location of demolition debris will be made after
the RIfFS is complete.
Comment:
Disposal/Converter:
1. Comment: The Town of Ruston, Tacoma officials and business
leaders accept the proposed incineration activities
on Site during demolition as long as the converter
meets all applicable Puget Sound Air Pollution
Control Authority (PSAPCA) and Ecology standards.
Specifically they suggested that Asarco' s converter
be subject to air quality advisories or alerts. In
addition the City of Tacoma Environmental
Commission requests assurance from EPA that
Ecology's sulfur dioxide standard [WAC 173-434-
130(3)] and PSAPCA's particulate standard for
refuse burning and BACT policy on carbon monoxide
will be met.
Response: See Section X.B.2.a. of the Record of Decision for
a description of requirements that will be imposed on any
incineration activities.

-------
2.
Comment:
One commentor wanted to know the basis forPSAPCA's
and Ecology's health standards establ ished for
acceptable air quality.
Response: EPA recommends that this
directly to PSAPCA and Ecology.
comment
be
submitted
Dust
1.
Comment:
One commentor wants to know if demolition of this
nature has been done before and whether the dust
suppression methods chosen for Asarco's stack
demolition were adequate in a project such as this.
Respo21~e: similar dl'st f"'lppression techniques have beel'
Su.cc~sdfull.f used for other. sh:..ilar deiUolition projects.
Smelter demolitions have been successfu~ly completed under EPA
oversight at other sites in the united States, e.g., Anaconda,
Montana. The oversight EPA will provide will have the benefit
of this and previous technical experience.
A complete design of the demolition will be planned and
approved by EPA before the work is initiated. EPA will require
that air monitoring devices be stationed around the demolition
site before the stack is imploded. They will measure ambient
air quality during all demolition activities. The air
surveillance and operation of these devices will monitor
compliance with health standards that have been established for
acceptable air quality by PSAPCA, EPA, Ecology and local
authorities.
Air will be monitored throughout the demolition process. If
elevated levels of contaminated materials are released, the
dust control methods will be augmented and, where appropriate,
work w1ll be stopped.
2.
Comment:
One commentor felt that since air monitoring
equipment measures in micrograms per cubic meter
of air there could not be any personal hazards from
these low levels during demolition.
Response: In order to ensure that exposures to arsenic and
particulates during demolition are not exceeding promulgated
standards or the acceptable exposure levels defined by EPA' s
Superfund program (generally those corresponding to a risk of
cancer of 1 in 10,000 to 1 in 1,000,000), monitoring will likely
be needed in the microgram per cubic meter range.

-------
3.
Comment:
One commentor was concerned that dust would blanket
the area within the 1,000 foot radius and adversely
affect his property.
Response: There will be dust control measures such as fogging
and misting in place to minimize dust releases during demolition
of the stack. Monitoring for ambient dust levels before,
during, and after demolition will measure the effectiveness of
the dust control measures.
Health
1.
Comment:
One commentor suggested that no proof was given
that arsenic was dangerous. Another commentor
asked what the threshold concentration for adverse
effects froID arsenic trioxide was; who established
these levels; what the basis of the threshold was.
Response: EPA responds that the adverse health effects from
exposure to arsenic have been confirmed in numerous public
health and scientific studies. Arsenic can cause a variety of
toxic effects in humans with the type and severity of effects
depending upon the level of exposure and. form of arsenic.
Inorganic arsenic has been recognized as a human poison for
decades and large doses can cause death. Human exposure to
lower levels of arsenic has resulted in injury to a number of
body tissues and organs, including the liver, kidneys, nervous
system, skin, and an increased risk of developing lung and skin
cancers. This increased risk of lung cancer has been observed
in numerous studies of workers who inhaled arsenic in smelters
and in a pesticide plant.
Increased incidence of skin cancers have been found in people
who have consumed drinking water contaminated with arsenic (for
example, in Taiwan and Mexico) and in those who used medicines
containing arsenic.
At the levels of arsenic found in the environment around the
Tacoma smelter, the health effects of most concern are skin and
lung cancer.
For chemicals which cause cancer, it is generally believed that
there is no level of exposure that does not pose some risk of
developing cancer. That is, there is no exposure level thought
to be risk-free. It is also assumed by EPA that the risk of
getting cancer increases as a person' s exposure increases.
Al though a "safe" or "threshold" exposure level can' t be defined
for a ca~cer-causing chemical like arsenic, estimates can be
made of the risk of getting cancer if the level of exposure to
that chemical is known.

-------
2.
Several commentors ~ugge~ted that because arsenic
is. a "non-cumutative poison" (doesn't build up in
the body) and is "removed from the system
naturally" data on its toxicity is inconclusive.

Response: EPA believes exposure to arsenic poses a risk of
developing adverse health effects. Once arsenic enTers the
body it is widely distributed thro~ghout the body through the
blood stream. The majority of it is then eliminated, primarily
in the urine, over a period of several days. As long as arsenic
remains in the body, there is the potential for it to cause
adverse effects. These adverse effects may be irreversible
(e. g ~ initiation of cancer) and therefore not dependent on
continued exposure. ;;
Comment:
In additioTi, as long as arsenic is present in the environment,
~.lthe ai£.or soil and- p90pla areexp~sed to it, arsenic can
continuously enter and be distributed in the body.
Safety
1.
Comment:
One commentor wondered if EPA anticipated any kind
of hazard during stack demolition outside the 1,000
foot evacuation radius.
Response: EPA does not anticipate a hazard from demolition
of the stack. As a prudent precautionary measure, however,
during stack demolitions people within an area twice the height
of the stack are typically asked to evacuate that area prior to
the demolition. Local authorities will be responsible for
coordinating the evacuation events and securing the area.
Costs
1.
One commentor wanted to know the cost of the total
demolition project.

Response: Estimated costs for the demolition or dismantlement
of the structures other than the stack are $9,192,000. The cost
of the explosive demolition, by implosion, of the smelter stack
is estimated at $720,000. Storage of the stack bricks in the
fine ore bins has capital costs estimated at $75,000 to
$260,000. Modification of the converter incinerator and
operation of the incinerator is estimated to cost $1,777,000.
The cost of diverting off-property surface waters to existing
drainage systems is estimated between $1,869,500 to $2,891,600.
Comment:

-------
One commentor suggested that EPA get cost estimates
to haul the debris to a iandfill in Arlington
Oregon by barge.

Response: If demolition debris is shipped off Site, EPA will
require Asarco to evaluate barge shipment and other
transportation alternatives.
2.
Comment:
3.
Comment:
One commentor wondered about the source of funding
for the demolition activities. .
Response: The next step after the Record of Decision is for
EPA to request that Asarco enter into a legal agreement, called
a Consent Decree, that will outline how Asarco will do the work
at its expense. If EPA and Asarco cannot agree, EPA could also
use its enforcement. authority to compel Asarco.to do the
demolition.. Also Superfund trust monies .could be used to. pay
for the demolition. EPA would then recover its costs from
Asarco.
Process

Comment:
Response:
activities.
2.
Comment:
One commentor thought that EPA ought to sell the
television rights to the demolition of the stack.

EPA is not seeking to make a profit on its cleanup
Several commentors indicated that the cleanup
efforts by EPA and Asarco were progressing too
slowly. They were concerned that the process is
going to continue indefinitely. There is also
concern about frequent changes in EPA staff who
are responsible for the cleanup. The commentors
believe these changes have a direct impact on the
completion of demolition and overall cleanup of
the site.
Response: The process of evaluating a large, complex site
like the Asarco smelter, evaluating possible cleanup
al ternati ves and implementing those technologies is a
complicated process. EPA is committed to completing its cleanup
activities at the smelter and adjacent areas as quickly as is
practicable.
One commentor wanted clarification whether this is
an EPA project or whether EPA is overseeing Asarco.

Response: The cleanup of Superfund si tes is an EPA
responsibility. Certain activities involved in a cleanup can
be conducted by the Potentially Responsible Party (PRP) under
the oversight of EPA. EPA has been overseeing Asarco's efforts
3.
Comment:

-------
since the Fall of 1986 when Asarco agreed to conduct. the
investigation under EPA guidelines and oversight. Based on this
information, EPA has determined the demolition plan and final
cleanup for the smelter Site. It is also EPA's responsibility
to make sure that the cleanup is implemented properly.
4.
A few comme~tors expressed concern that the public
comments solicited by EPA were not taken seriously.

Response: EPA has considered all comments submitted during
the sixty day public comment period on its proposed demolition
activities. All of the comments received are included in this
Responsiveness Summary' and similar comments are grouped
together. EPA has made:, modifications to the details of its
demolition plan based on public comments. EPA has included
plans to survel ~he car and ~~il turnels and the roads around
Ruston ih respo..~e to public comments. : In addit-ion, EPA has
modified its plans for protective measures during the stack
demolition to include a protective layer over the visqueen
ground cover and additional drainage protection to ensure that
water use to control dust is collected. EPA will continue to
seek and consider public comments throughout the cleanup of
Asarco related projects.
Comment:
5.
Comment:
One commentor expressed concern that the Lige-
Dickson trucks that have been entering and exiting
the Asarco facility have been running over the
curb, while transporting soils from the ERA sites,
as they turn the corner. The comment or is
concerned that continued activities of the nature
will ruin the streets in Ruston.
Response:

request that
the future.
Lige-Dickson is an Asarco subcontractor. Although
ERA sites is complete for this season, EPA will
Asarco direct its contractors to take more care in
other Related proiects
The remaining questions and comments made during the public
meeting in Ruston on August 16, 1990 pertained to the off-site
properties that fall into two operable units, 1) the Expedited
Response Action (ERA) which consists of 11 publicly accessible
lands and 2) the Ruston/North Tacoma Study Area which includes
private residential lands. Questions were also related to arsenic
as a contaminant and its threat to human health.
1.
Comment:
One commentor noted that the News Tribune said that
"Legal requirements hold companies perpetually
liable for environmental contamination or health

-------
protection from Superfund sites.1I He wondered if
that was true or if there were some qualifications.
Response: Under CERCLA, companies responsible for
contaminating property are liable, even after the cleanup has
been conducted, for hazardous substances that remain on Site.
If such hazardous substances cause health or environmental
problems in the future, responsible parties are responsible for
taking additional actions to respond to that problem.
2.
Comment:
The same commentor asked if this same liability
would apply to private properties that are
contaminated with arsenic. Are private property
owners responsible if they want to develop their
land? .
Response: Under CERCLA's' broad liability provisions~ in
addition to the companies responsible for releasing hazardous
substances into the environment, owners of property at the time
that hazardous substances are disposed of on that property may
be liable for the government's costs to cleanup the site. At
the Asarco Site, however, EPA does not expect that it will be
necessary for individuals that own contaminated property to
participate in funding cleanup costs. EPA cautions individual
property owners that improper handling or disposal of
contaminated soil may result in liability under federal and
state environmental laws. EPA is now working with state and
local health and environmental agencies to develop guidelines
on conducting activities, including development of residential
properties, in an appropriate manner.
3.
Comment:
One commentor stated that he did not understand
why soils need to be capped on the ERA sites. They
stated that so far the data was inconclusive as to
the degree of harm caused by these soils since
arsenic was removed from the body naturally. Also
they stated that it was natural for kids to grow up
and go to school, therefore decreasing the amount
of time they spent playing in the dirt and their
contact with arsenic contamination. Commentors
suggested that no proof, such as cancer deaths, has
been given that arsenic is dangerous.
Response: Past samples taken from the Ruston/North Tacoma
area have revealed levels of arsenic in the soil greater than
what is expected in an urban environment. These elevated levels
are a result of operations at the ASARCO smelter.
As previously discussed in question number one under the Health
section of this Responsiveness Summary, health effects from
arsenic depend upon the form of arsenic as well as the degree
and duration of exposure. Potential health effects from

-------
exposure to arsenic include skin and lung cancer. In order,for
the arsenic to have an adverse" impact on health, however, a
mechanism for exposure to the arsenic must exist. In the
Ruston/North Tacoma area the concern is that people may be
exposed. to arsenic. by inhalation or ingestion of arsenic
contaminated soils. Children are of particular concern because
of their ~endency to play in soil and to touch their fingers to
their mouths. Children playing in contaminated soil increase
their exposure and intake by getting contaminated material and
dirt in their mouth.
Although it is true that children grow up and go on to school,
the Endangerment Assessment (EA) completed for the EPA in 1988
estimated that a large proportion of a persons lifetime dose of
arsenic from exposure. t'o soil occurs before age 7. Also,-
..::l.ildren who e.re j n sc"oc.' (gradE:> school through high school)
'often .3peud a sUbstantial po:::'tio~'1 ,~f t.heir non~school ti:::e at
or near their homes, ana may be attending a school that has
elevated arsenic levels in its soil. While it is true that
arsenic is excreted from the body within several days of
exposure, EPA is concerned about its potential effects prior to
excretion. So long as arsenic remains in the soil, there is the
potential for continuous exposures.
The action taken at the ERA sites involves removing the soil
from the surface (3 inches) and capping with clean soil. This
action reduces the potential for direct contact by the public
with contaminated soils.
4.
Comment:
Commentors wondered why the EPA was not working
more closely with the Tacoma pierce County Health
Department (TPCHD) and why the TPCHD was not more
concerned about the arsenic contamination.
Commentors viewed the discontinuation of the
moni toring program of urinary arsenic levels as
proof that arsenic. was not the problem it was
claimed to be. Also a commentor wondered what
happened to the study on death rates as correlated
with arsenic levels that was to be conducted by the
State Department of Health, and why this study was
not completed before claiming the area was
hazardous.
Response: EPA and the TPCHD have had a long history of
cooperative involvement. The agencies have worked jointly on
developing and implementing community relations efforts and
community workgroups. In. addition, the TPCHD reviews and
comments on EPA documents. CUrrently EPA and TPCHD are.
cooperating on producing guidelines on the safe handling and
removal of soil potentially contaminated with arsenic. As the
local health agency, TPCHD continues to offer advice and
information to the public on various arsenic related issues.

-------
There has never been a urinary arsenic. monitoring "program"
per see In the past, urinary arsenic monitoring was conducted
as part of a larger study. As EPA recognized the interest
within the community for this service, a provision was included
in the March 8, 1989 Consent Order (signed by EPA and Asarco)
for Asarco to provide funding to the TPCHD for the purpose of
conducting urinary arsenic testing. Asarco and the TPCHD have
developed a plan to make further testing available to members
of the community who desire it.
While urinary arsenic m~nitoring is used as a tool to determine
if people may have been.'exposed to arsenic, it is important to
recognize its shortcomings. The Toxicological Profile for
Arsenic prepared by the u.s. Public Health Service offers the
. following regarding the interpretation of urinary arsenic
monitoring results: ."A number of. biomonitoring.'.options are
available for estimating short-term and long-term arsenic
exposure levels in humans. Arsenic levels in blood, urine,
hair, and nails all tend to increase with increasing exposure,
but there is a wide range in "normal" levels, and values in
people wi th moderate levels of exposure are sometimes not
distinguishable from typical "background" levels. In addition,
in the low to moderate exposure range of chief concern, there
is not a strong correlation between arsenic levels in these
fluids or tissues and the onset of arsenic-induced toxicity.
Thus, these biomarkers are of limited utility in judging the
health risk to populations with low to intermediate levels of
arsenic exposure."
The study currently being conducted by the State Department of
Health (DOH) is designed to evaluate the effect of arsenic
exposure on the mortality rates in children residing close to
the smelter. Only male children are being studied. All boys
born between 1895-1925 who lived north of 35th street in Tacoma.
for two or more years prior to age 14 are included in the study.
A residence history is being determined for each boy using
school records, city directories and other records. Exposure
level will be based on the distance of the child's residence
from the smelter, the number of years at each residence, and the
time period of exposure. It is expected that death certificates
will provide information on cause and date of death. DOH
anticipates that the study will be completed in March 1991.

In addition to the study currently being conducted by the DOH,
other epidemiologic studies have been performed in the community
surrounding the Tacoma smelter. For example these included
studies on non-cancer health affects and on lung cancer deaths.
All of these studies to date have found no statistically
significant increases in adverse health outcomes associated with
arsenic exposure. It is important to note that no epidemiologic
studies of skin cancer incidence within the community have been

-------
performed.
In general, EPA does not rely on epidemiologic studies done in
a community to make cleanup decisions about that community.
These studies are typically done based on historical records
where, in most cases, people have already died from certain
exposures. It is not appropriate to wait until a study shows
death via some exposure to take action to address that concern.
EPA's Superfund guidance states that, in general, acceptable
, exposure levels are those that represent an upper bound lifetime
cancer risk to an individual of between 1 in 10,000 to 1 in
1,000,000. As shown by the following example, epidemiological
studies, especially those conducted in a small population, are
"ot likely to be able to detect such risks. Ifa population of
5,000 is cxpose..J. to a contaminant such that the individual
litetime cancer risk would be 1 in 10,000, then about 0.5 or one
half of a cancer case would be expected to be detected in that
population over a 70 year period (or one cancer case in 140
years) .
One additional cancer case in 140 years is extremely difficult
if not impossible to detect in epidemiological studies. This
is especially true for lung and skin cancers (those associated
with arsenic exposure) since the number of people within the
population with these types of cancer is already very high. For
example, about 70 to 90 people die from lung cancer in Tacoma
each year. Therefore, while positive results of an
epidemiologic study may help support the need to take a
particular cleanup action, the absence of statistically
significant increases in adverse health outcomes does not prove
that adverse health effects will not occur.
5. Comment: One commentor asked about the methodology of collecting
and evaluating samples on residential and ERA
properties. The commentor wondered why a cap was
sufficient even if contamination was found at deeper
levels, shouldn't all contaminated soils be removed
and disposed. In the case that a tree was planted
after the cap was in place, wouldn't exposure to these
contaminated soils be an unacceptable risk.
Response: In general, we expect the majority of contamination
to be at the surface of the soils. Due to its nature arsenic
does not leach, wash or move off the soils, very well into the
soils below. However, this pattern is not always true. Sample
results for depth samples were inconsistent from one set to the
next. For example, it is possible to find higher values of
arsenic at depth than at the surface. This is due to removal
and/or redeposition of contaminated and clean soils over the 100
year operational history of the smelter. In addition, both

-------
natural and man-made forces (erosion, wind, development, anq
excavation) may contribute to 'this 'pattern. Black and Veatch
prepared a Final Field Investigation Report-Ruston/Vashon Island
Area (September 1988) for Ecology detailing their field
investigation, evaluation of data and the extent of
contamination.
Soil removal and capping may not eliminate all contaminated
soil, but significantly reduces the potential for arsenic
exposure: if properly maintained, a cap adequately reduces
health risks. The amount of exposure that one could get by
digging a hole to plant. a tree is relatively short term and may
not be 'unacceptable if' appropriate procedures are followed.
Currently EPA is working:: on guidelines on how to conduct such
activities to reduce exposure. When the ERA sites were capped,
property owners signed access agreements with Asarco that
delineated responsibilities for maintenance of the protective
caps. Any such capping activities conducted on residential
properties in the future would be subject to similar provisions.
6.
Comment:
pertaining to the soils in the Ruston and North
Tacoma area one commentor noted that the City has
required that the topsoil be scraped away to
preclude future problems with arsenic
contamination. The commentor wondered if this was
a necessary requirement of city planning.
Response: EPA is not aware of any such requirements of the
City of Tacoma or the Town of Ruston. We believe that the
commentor is referring to a specific development issue that
surfaced in 1981. At that time a developer wanted to build a
housing project in Tacoma using federal. funds offered through
the Department of Housing and Urban Development. An
Environmental Impact Statement, required for the project,
revealed a concern with arsenic contaminated soil. As a
condition of development the developer was required to scrape
the top two inches of soil.
7.
Comment:
One commentor expressed concern that the Yacht Club
peninsula is comprised entirely of Asarco slag and
was worried about the effects of this on the
environment. The commentor thought that this slag
was exposed and was curious as to EPA's oversight
of the need for slag cleanup at the Yacht Club
property. Another commentor wondered if the Yacht
Club property was covered with asphalt.
Response: At present there is no discrete study of the Yacht
Club. Environmental problems associated with the slag, such as
that which makes up the Tacoma Yacht Club peninsula, are being
investigated by EPA as part of two separate but related
projects. One project is the Remedial Investigation/Feasibility

-------
study (RI/FS) for the Asarco smelter property, and the othe+ is
an RI/FS for the marine 'sedimentsoffshore of the smelter
property, including the Yacht Club peninsula. The RI/FS for the
smelter property will evaluate the need for site cleanup and
stabilization measures, including what to do about exposed slag
on this property. The RI/FS for the marine sediments will
evaluate the need for cleanup and stabilization of sediments as
well as the slag making up the shoreline. Currently EPA is
evaluating the toxicity and leachability of slag in an Asarco
off-Property study. The leachability study and both RI/FS
investigations will be provided to the public for review and
comment.
8.
Comment:
One commentor asked about the original and recent
samples collected at Point. Defiance Park and their
con~~mination lev~ls.
Response: The original samples collected in the Point
Defiance Park area by Black and Veatch for the Department of
Ecology in 1988 show arsenic concentrations below the 250 ppm
action level established for high use areas during the expedited
response actions. A limited number of additional surface soil
samples were collected from the Park during the most recent
round of sampling in June 1990 in order to supplement existing
data and clearly delineate surface arsenic concentrations.
9.
Comment:
One commentor asked about the direction of the
prevailing winds.

Generally in a southwesterly direction.
Response:
10. Comment:
One commentor suggested that the opinions and
suggestions of the Ruston workgroup were not the
representative opinions or attitudes held by the
whole community.
Response: The opinions and suggestions of the entire
communi ty are important to EPA and we hope that this is
evidenced by the community relations efforts the Agency has
taken over the past year. The establishment of the Ruston/North
Tacoma Workgroup and a community liaisons office in Ruston were
accomplished in an effort to be responsive to community
concerns. EPA has invited anyone who is interested to join the
workgroup or to attend any meetings where the topics are of
interest. In addition, EPA continues to distribute fact sheets
to interested individuals on activities related to the Superfund
activities in the area, and to hold public meetings at critical
decision making points in the Superfund process in order to get
public input. Staff are available to meet with individuals or
small groups on topics of interest.
EPA
is
interested
in
meeting
the
community's
needs
for

-------
information and believe's that community involvement is very
important in designing a successful cleanup for the Asarco site.
Members of the community are encouraged to talk to EPA
representatives about their concerns or suggestions for public
involvement.
