I. Introduction
EPA Region 10 announces its intent to delete the Allied Plating
site from the National Priorities List (NPL), Appendix B of the
National Oil and Hazardous Substances Contingency Plan (NCP), 40 CFR
Part 300, and requests comments on this deletion. EPA identifies sites
that appear to present a significant risk to human health or the
environment, and places these sites on the NPL. EPA has the discretion
to use its authorities under CERCLA or RCRA, or to designate a state
with remedial authorities to accomplish appropriate cleanup at sites
listed on the NPL. As described in Sec. 300.425(e)(3) of the NCP, sites
deleted from the NPL remain eligible for Fund-financed remedial actions
in the unlikely event that conditions at the site warrant such actions.
EPA plans to delete the site, located at 8135 Martin Luther King,
Jr. Boulevard, Portland, Oregon, from the NPL.
EPA will accept comments on this proposal to delete this Site for
thirty days after publication of this notice in the Federal Register.
Section II of this Notice explains the criteria for deleting sites
from the NPL. Section III discusses procedures that EPA is using for
this action. Section IV discusses the Allied Plating Site and explains
how the Site meets the deletion criteria.
II. NPL Deletion Criteria
Section 300.425(e) of the NCP, 40 CFR 300.425(e), provides that
sites may be deleted from, or recategorized on, the NPL where no
further response is appropriate. In making a determination to delete a
site from the NPL, EPA shall consider, in consultation with the State,
whether any of the following criteria have been met:
(1) EPA has determined that responsible or other parties have
implemented all appropriate response actions required; or
(2) All appropriate Fund-financed responses under CERCLA have
been implemented, no further cleanup by responsible parties is
appropriate; or
(3) The remedial investigation has shown that the release poses
no significant threat to public health or the environment and
therefore, taking remedial measures is not appropriate.
III. Deletion Procedures Followed for the Allied Plating Site
The following procedures were used for the intended deletion of
this Site:
(1) EPA Region 10 has determined that the Site was successfully
remediated through a Removal Action which took place in the fall of
1992. On June 29, 1993, EPA issued a No Further Action Record of
Decision (ROD) after the public comment period ended. No comments
were received.
(2) EPA Region 10 has recommended deletion of the Site and has
made the relevant documents available to the public for review in
the information repositories.
(3) The Oregon Department of Environmental Quality has concurred
with the deletion decision.
Deletion of the Allied Plating Site from the NPL does not itself
create, alter, or revoke any individual rights or obligations. The NPL
is designed primarily for informational purposes to assist EPA
management. As mentioned in Section II of this Notice, 40 CFR
300.425(e)(3) states that deletion of a site from the NPL does not
preclude eligibility for future Fund-financed response actions.
For deletion of this Site, EPA's Regional Office will accept and
evaluate public comments on EPA's Notice of Intent to Delete before
making a final decision to delete. The EPA will prepare a
Responsiveness Summary, if necessary, addressing significant public
comments.
A deletion occurs when the Regional Administrator places a final
notice in the Federal Register. Generally, the NPL will reflect
deletions in the final update following the notice. Public notices and
copies of the Responsiveness Summary will be made available to local
residents by the Regional EPA office.
IV. Basis for Intended Site Deletion
The following site summary provides EPA Region 10's rationale for
the intention to delete the Allied Plating Site from the NPL.
The Allied Plating Site is located at 8135 Martin Luther King, Jr.
(MLK) Boulevard, in an industrial and commercial district of
northeastern Portland, Multnomah County, Oregon.
The Site covers approximately 12 acres, and contained the buildings
which formerly housed a plating operation and a waste disposal area
approximately 3 acres in size.
In 1957, the buildings were leased for the operation of Allied
Plating, Inc., a chrome plating facility which operated from that year
until 1984, when the company declared bankruptcy and ceased operations.
Prior to 1969, wastewater from the facility was discharged to a
swale leading to the Columbia Slough (an off-site water body). After
1969, landfilling north of the property cut off natural drainage, and
as a result the discharge of liquid wastes from the plating facility
created a lagoon on-site. The metals in the plating wastewater
precipitated out, forming a layer of plating waste at the bottom of the
lagoon. Aerial photographs indicate that the lagoon covered
approximately 3 acres during the time when the company was discharging
plating wastes into the lagoon. After the company ceased its
discharges, the lagoon receded, leaving a small pond with the
surrounding area covered with plating waste.
EPA conducted a Remedial Investigation (RI) at the Site between
January 1990 and April 1992. The RI determined that the Site
contamination was mainly limited to the area formerly covered by the
lagoon.
Following the RI, the Site was evaluated for a potential Removal
Action as part of the Superfund Accelerated Cleanup Model (SACM)
Program. The Site met the criteria for remediation under a Removal
Action. This Removal Action took place between October 20 and November
10, 1992. During the Removal Action, the pond was drained, and the pond
sludges and the plating waste in the surrounding areas were excavated
and shipped off-site for disposal at Envirosafe Services, Inc., in
Grandview, Idaho (a facility identified by EPA as being eligible to
receive CERCLA wastes). Approximately 1100 cubic yards of sludge and
waste were excavated and disposed of in this manner. The Site owner
also placed a deed restriction on the Site property, preventing the use
of the shallow groundwater beneath the Site. The RI had determined that
one well in this aquifer had nickel concentrations above drinking water
standards.
Following the Removal Action, EPA conducted a risk assessment on
the contaminant concentrations remaining in the surface soils of the
Site. Although the remediated area had been backfilled during the
Removal Action by at least one foot of rock, to be conservative in the
analysis, it was assumed that there would be direct human exposure to
the remaining residual contaminant concentrations. The results
indicated that the Removal Action achieved a site cleanup level which
left the health threat associated with site-related contaminants well
below a 1 x 10-4 excess cancer risk. The remaining hazard index
was 2 for a residential scenario and 0.2 for an industrial scenario. A
hazard index of 1 is the level where no toxic effects are expected to
occur.
This residual contamination level is negligibly above levels that
would allow for unlimited use and unrestricted exposure. The Site was
remediated to industrial standards. The Site is currently used for
light industry and is expected to remain so, given the historical land
use in this area. In addition, although the remaining surface
contamination level had a residential hazard index of 2, the residual
contamination is buried under one or more feet of crushed rock used as
backfill; therefore, no contact route exists.
EPA signed a Record of Decision for no further action at the Allied
Plating Site on June 29, 1993. The Oregon Department of Environmental
Quality concurred with the no further action remedy selection.
EPA believes that the implemented remedy at the Allied Plating Site
is protective of the public health and the environment. All possible
exposure pathways from contamination on-site have been addressed,
including groundwater and near-surface soils.
A five year review is scheduled to be conducted at the Allied
Plating Site by June 1998. If EPA determines that the remedy is still
protective of public health and the environment, no further five year
reviews will be conducted.
EPA has determined that all appropriate Fund-financed responses
under CERCLA at the Allied Plating Site have been completed, and that
no further cleanup by responsible parties is appropriate. The Oregon
State Department of Environmental Quality has concurred with this
decision.
Dated: August 1, 1994.
