I. Introduction

    EPA, Region IV, announces its intent to delete the Site from the 
NPL, which constitutes Appendix B of the NCP, and requests comments on 
this proposed deletion. EPA identifies sites that appear to present a 
significant risk to public health, welfare, or the environment and 
maintains the NPL as the list of those sites. Sites on the NPL may be 
the subject of remedial actions financed by the Hazardous Substances 
Superfund (Fund). Pursuant to Sec. 300.425(e)(3) of the NCP, any site 
deleted from the NPL remains eligible for Fund-financed Remedial 
Actions in the unlikely event that conditions at the site warrant such 
action.
    EPA will accept comments concerning this Site until March 13, 1995.
    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 how the Site meets the deletion 
criteria. [[Page 7935]] 

II. NPL Deletion Criteria

    The NCP establishes the criteria that the Agency uses to delete 
sites from the NPL. In accordance with 40 CFR 300.425(e), releases may 
be deleted from the NPL where no further response is appropriate. In 
making this determination, EPA will consider, in consultation with the 
State, whether any of the following criteria have been met:
    (i) Responsible or other parties have implemented all appropriate 
response actions required; or
    (ii) All appropriate Fund-financed responses under CERCLA have been 
implemented and no further cleanup by responsible parties is 
appropriate; or
    (iii) The remedial investigation has shown that the release poses 
no significant threat to public health or the environment and, 
therefore, taking of remedial measures is not appropriate.

III. Deletion Procedures

    EPA Region IV will accept and evaluate public comments before 
making a final decision to delete. Comments from the local community 
may be the most pertinent to deletion decisions. The following 
procedures were used for the intended deletion of this Site:
    (1) EPA, Region IV, has recommended deletion and has prepared the 
relevant documents. (2) The State has concurred with deletion decision. 
(3) Concurrent with this National Notice of Intent to Delete, a local 
notice has been published in local newspapers and has been distributed 
to appropriate federal, state, and local officials, and other 
interested parties. (4) The Region has made all relevant documents 
available in the Regional Office and local site information repository.
    Deletion of a site from the NPL does not itself, create, alter, or 
revoke any individual rights or obligations. The NPL is designated 
primarily for information purposes and to assist Agency management. As 
mentioned in Section II of this document, 40 CFR 300.425(e)(3) provides 
that deletion of a site from the NPL does not preclude eligibility for 
future Fund-financed response actions.
    The comments received during the notice and comment period will be 
evaluated before the final decision to delete. The Region will prepare 
a Responsiveness Summary, if necessary, which will address any comments 
received during the public comment period.
    A deletion occurs when the EPA Regional Administrator publishes a 
notice in the Federal Register. The NPL will reflect any deletions in 
the next final update. Public notices and copies of the Responsiveness 
Summary will be made available to local residents by Region IV.

IV. Basis for Intended Site Deletion

    The following summary provides the Agency's rationale for the 
intent to delete this Site from the NPL.
    The Wilson Concepts Site occupies approximately two acres in a 
highly industrialized section of northeastern Broward County, Pompano 
Beach, Florida. Associated operations at the facility included 
precision machining, drilling, and milling of metal parts, vibratory 
deburring, degreasing, steam cleaning, and spray coating of parts. A 
variety of chemicals were used, including organic solvents, chlorinated 
solvents, petroleum products, paints, cyanides, acids, and bases.
    From 1976 through 1989, several inspections were conducted by 
Broward County Environmental Quality Control Board (BCEQCB) which 
documented poor waste handling practices, including discharge of 
industrial wastes onto the ground. Raw materials usage at the Site was 
documented on two occasions over a period of 10 years. In the early 
1980's, possibly as early as 1981, Wilson Concepts submitted a 
hazardous materials inventory list to the BCEQCB. The chemicals used at 
the Site included a variety of hydraulic and lubricating oils, metal 
protection agents, water coolants, methylene chloride, methyl ethyl 
ketone, and chemical cleaners (possibly corrosives). In August 1985, 
EPA conducted a Preliminary Assessment of the Site and in July 1986 
requested its contractor, NUS, to perform a Sampling Investigation. The 
results of this sampling caused the Site to be proposed for the NPL in 
July 1988. In March 1989, the Wilson Concepts Site, of Florida, was 
formally included on the NPL.
    The Remedial Investigation (RI) was conducted in two phases, phase 
I in 1990 and phase II in 1991. The groundwater contaminant levels 
detected at the Site during the RI were much lower than those detected 
during the Site Listing Investigation (SLI). Most of the contamination 
consisted of organic compounds which easily evaporate and/or naturally 
degrade. Trichloroethylene was detected in two monitoring wells during 
the first sampling event but was not detected above groundwater 
standards in phase II, indicating that no distinct groundwater 
contaminant plume existed. Chromium and strontium along with low levels 
of orgaincs including toluene were detected in Site soils. Chromium was 
observed in two locations in subsurface soils at elevated levels. 
Though similar organic contaminants were detected during the RI, the 
concentrations were much lower than previously detected and were within 
the range considered by EPA to be safe for human exposure. It is 
possible that the organic contamination was reduced by natural 
attenuation.
    The Record of Decision (ROD), issued by EPA, Region IV, on 
September 22, 1992 selected alternatives consistent with the 
recommendation in the Feasibility Study. The remedy is a ``No Action'' 
remedy which included monitoring of on-site ground water, quarterly, 
for a one-year period to confirm the appropriateness of the no action 
remedy.
    The EPA community relations activities at the Site included a 
public meeting in July 28, 1992 to present to the public the Agency's 
Proposed Plan for Remediation at the Site. Public comments received 
during a 30-day comment period were received and addressed in the 
Responsiveness Summary. The major concerns included the Site's affect 
on local wells and water bodies, residual dangers from the Site, what 
has happened to the contaminant concentrations that allowed the Site to 
be placed on the National Priorities List, how the monitoring will be 
conducted and what will happen when the monitoring is completed. The 
Responsiveness Summary was included as an appendix to the ROD.
    A Post ROD Project Operations Plan for the Site was completed on 
May 25, 1993. Field work for Post ROD ground water monitoring begin on 
June 21, 1993, and was completed on July 18, 1994. Post ROD ground 
water monitoring confirmed that Site related contaminants had declined 
in concentration and are below maximum contaminant levels (MCLs). 
Sporadic detections of iron, manganese and aluminum do not appear site 
related. During the Remedial Investigation drums were left on the Site. 
Those drums since have been sampled. No contaminants of concern were 
detected in either the drummed soil or aqueous samples. The Agency for 
Toxic Substances and Disease Registry (ATSDR) completed a health 
assessment for the Site in May, 1990. ATSDR reviewed the surface water 
and ground water data and recommended that the Site should not be 
considered for follow-up health studies due to no present exposure to 
population.
    No institutional controls are necessary for the Site. A five-year 
ground water review will not be conducted because contaminants of 
concerns have achieved levels below MCLs, which was verified 
[[Page 7936]] through Post ROD monitoring. These levels indicated that 
no future threats to the public health or environment exist. EPA and 
the State find that the remedy continues to provide adequate protection 
of human health and the environment. Therefore, EPA proposes to delete 
the Site from the NPL.
    EPA, with concurrence of the State of Florida, has determined that 
all appropriate Fund-financed responses under CERCLA at the Wilson 
Concepts Site have been completed, and that no further cleanup by 
responsible parties is appropriate.
