ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 300

[FRL-5428-3]


National Oil and Hazardous Substance Pollution Contingency Plan; 
National Priorities List

AGENCY: Environmental Protection Agency.

ACTION: Notice of intent to delete the Amnicola Dump Superfund Site, 
Chattanooga, Tenn., from the National Priorities List (NPL).

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

SUMMARY: The Environmental Protection Agency (EPA) Region 4 announces 
its intent to delete the Amnicola Dump Site from the National 
Priorities List (NPL) and request public comment on this proposed 
action. The NPL constitutes Appendix B of 40 CFR Part 300 which is 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 Tennessee Department of the 
Environment & Conservation have determined that the Site poses no 
significant threat to public health or the environment, therefore, 
further remedial measures pursuant to CERCLA are not appropriate.

SUPPLEMENTARY INFORMATION:

Introduction

    The Environmental Protection Agency (EPA) Region 4 announces its 
intent to delete the Amnicola Dump Site from the National Priorities 
List (NPL), Appendix B of National Oil and Hazardous Substances 
Pollution Contingency Plan (NCP), 40 CFR part 300, and requests 
comments on this deletion. EPA identifies sites that appear to present 
a significant risk to public health, welfare, or environment and 
maintains the NPL as the list of these sites.
    As described in 300.425(e)(3) of the NCP, sites deleted from the 
NPL remain eligible for remedial actions in the unlikely event that 
conditions at the site warrant such action.
    EPA will accept comments on the proposal to delete this Site for 
thirty days after publication of this notice in the Federal Register.

NPL Deletion Criteria

    Section 300.425(e) of the NCP provides that sites may be deleted 
from the NPL where no further response is appropriate. EPA, in 
consultation with the State of Tennessee, has concluded that the 
Amnicola Dump Site meets the following criteria for site deletion:
    (i) Responsible parties have implemented all appropriate response 
actions required; and
    (ii) All appropriate response under CERCLA has been implemented.
    Even if a site is deleted from the NPL, where hazardous substances 
remain at the site above levels that allow for unlimited use and 
unrestricted exposure, EPA's policy is that a subsequent review of the 
site will be conducted at least every five years after the initiation 
of the remedial action at the site. If new information becomes 
available which indicates a need for further action, EPA may initiate 
remedial actions. Whenever there is significant release from a site 
deleted from the NPL, the site may restored to the NPL without the 
application of the Hazardous Ranking System.

Deletion Procedures

    The following procedures were used for the intended deletion of 
this Site: (1) EPA Region 4 issued a Final Close Out Report which 
addressed the Site conditions, quality assurance and control during 
construction, and technical criteria for satisfying the completion 
requirements; (2) a notice has been published in the local newspaper 
and has been distributed to appropriate federal, state, and local 
officials announcing the commencement of a 30-day public comment period 
on EPA's Notice of Intent to Delete; and (3) all relevant documents 
have been made available for public review in the local Site 
information repositories.
    Deletion of the Site from the NPL does not itself create, alter, or 
revoke any individual's rights or obligation. The NPL is designed 
primarily for information purposes and to assist Agency management. As 
mentioned in Section VI of this document, Sec. 300.425(e)(30) of the 
NCP states that deletion of a Site does not preclude eligibility for 
future response actions.
    For deletion of this Site, EPA's Regional Office will accept and 
evaluate public comments of EPA's Notice of Intent to Delete before 
making a final decision to delete. If necessary, the Agency will 
prepare a Responsiveness Summary to address any significant public 
comments received.
    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 office.

Basis For Intended Site Deletion

    The following site summary is the Agency's rationale for the 
proposal to delete Amnicola Dump from the NPL.

A. Site Background and History

    The Site is an 18-acre inactive construction debris disposal area 
located in Chattanooga, TN. From mid-1970 to 1973, the Site was 
operated as a construction debris disposal area by the city of 
Chattanooga. The debris disposed included 25 percent or less 

[[Page 6807]]
household-type waste. A substantial portion of the wood waste taken to 
the Site during this period was incinerated by an air-curtain 
destructor with the ashes placed on-site. Approximately 12 acres of the 
18-acre site were eventually filled.
    Consolidated Latex, Inc., formerly located on the south border of 
the Site, allegedly disposed of latex waste in the southwest corner. In 
1971, the Tennessee-American Water Company noted the dumping of latex 
waste as well as the presence of a strong styrene-like odor during one 
leachate sampling event. Concern arose because of the proximity of the 
water company's intake from this leachate stream and alleged latex 
disposal location. Latex waste is the only industrial waste reportedly 
disposed at the Site. In May 1971, EPA recommended closure of the Site.

B. Remedial Planning Activities

    The State of Tennessee conducted a site visit in July 1979, and 
noted that the Site was in good overall condition; however, some 
discoloration of water was observed in one of the drainage ditches. EPA 
recommended an evaluation of historical water data and further water 
sampling.
    Sampling of a leachate stream indicated the presence of 
trichloroethylene, vinyl chloride, and 1,2 transdichloroethyleno. The 
Site was finalized on the NPL in September 1983.
    A Remedial Investigation (RI) of the Site commenced in July 1987; 
EPA conducted this RI to determine the nature and general extent of 
Site contaminants. A Feasibility Study (FS) was also conducted by EPA 
to evaluate alternatives for Site cleanup. Sampling data from the RI 
indicated that some surface soils on the Site contained concentrations 
of Polynuclear Aromatic Hydrocarbons (PAHs) above acceptable health 
based levels.
    On March 30, 1989, EPA issued a Record of Decision (ROD) for the 
Site which selected a remedy for the contamination detected. The major 
remedy components selected for the Site consisted of excavation of 
surface soil and debris, solidification of the surface soil, and 
groundwater monitoring.

C. Remedial Construction Activities

    On-Site excavation of contaminated soil and debris started on 
August 5, 1993, and the material was shipped off-site for disposal. The 
excavated material included pieces of creosote ties, asphalt chips, 
bricks, concrete, contaminated soil and other debris. Excavation was 
completed on August 5, 1993, and confirmatory cleanup samples were 
taken. Once the confirmatory samples indicated that the excavated area 
no longer contained soil levels over the cleanup goal, the area was 
then filled with crushed stone for easy identification.
    The final inspection was performed on September 2, 1993. The 
inspection was performed by EPA and Tennessee Department of Environment 
and Conservation (TDEC) representatives. It was determined that the 
Remedial Action had been successfully executed.
    Confirmatory soil sampling taken before and after the soil removal 
has demonstrated that contaminant levels in the surface soil are now 
below the cleanup goal. Results of the sampling can be seen in the 
August 1993, Remedial Design Report and the September 1993, Remedial 
Action Report. No Site contaminants have been detected in the 
groundwater above the levels established in the ROD.

D. Community Relations Activities

    The Region 4 Community Relations staff along with the Site project 
manager conducted an active campaign to ensure that the local residents 
were well informed about the different activities occurring at the 
Site. Community relations activities included the development of 
Community Relations Plans, holding public meetings, and routine 
publications of progress report fact sheets. Site information was 
placed at a local repository located in the Chattanooga/Hamilton County 
Bicentennial Library.

E. Summary of Operation and Maintenance

    Since all surface soil above the cleanup goal has been removed, and 
as no operating systems or containment measures were necessary, 
Operation and Maintenance (O&M) of the Site is not required. Site 
Institutional Controls were defined in the Consent Decree to place deed 
restrictions on the property.

F. How Amnicola meets NPL Deletion Criteria

    Section 300.425(e) of the NCP provides that sites may be deleted 
from the NPL where no further response is appropriate. EPA, in 
consultation with the State of Tennessee, has concluded that the 
Amnicola Dump Site meets the following criteria for site deletion:
    (i) Responsible parties have implemented all appropriate response 
actions required; and
    (ii) All appropriate response under CERCLA has been implemented.

G. State Concurrence To Delete Amnicola Dump Site

    EPA, in consultation with the State of Tennessee, has concluded 
that the Amnicola Dump Site meets the following criteria for site 
deletion: (1) Responsible parties have implemented all appropriate 
response actions required; and (2) All appropriate response under 
CERCLA has been implemented. EPA and the State of Tennessee believe 
that the above listed criterion for deletion has been met. 
Subsequently, EPA is proposing deletion of Amnicola Dump Site from the 
NPL. Documents supporting this action are available from the docket.
