National Oil and Hazardous Substances Pollution Contingency Plan; 
National Priorities List Update

AGENCY: Environmental Protection Agency.

ACTION: Notice of intent to delete Allied Plating from the National 
Priorities List: request for comments.

-----------------------------------------------------------------------

SUMMARY: The United States Environmental Protection Agency (EPA) Region 
10 announces its intent to delete the Allied Plating Site (Site) from 
the National Priorities List (NPL) and requests public comment on this 
proposed action. The NPL constitutes Appendix B to the National Oil and 
Hazardous Substances Pollution Contingency Plan (NCP), which EPA 
promulgated pursuant to Section 105 of the Comprehensive Environmental 
Response, Compensation, and Liability Act (CERCLA) of 1980, as amended. 
EPA and the state of Oregon Department of Environmental Quality (DEQ) 
have determined that all appropriate actions under CERCLA have been 
implemented and that no further cleanup of the Site under CERCLA is 
necessary. Moreover, EPA and DEQ have determined that remedial 
activities conducted at the Site to date have been protective of public 
health, welfare and the environment.

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.
