AGENCY: Environmental Protection Agency.

ACTION: Notice of intent for partial deletion of the French Limited

Superfund Site from the National Priorities List.

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

SUMMARY: The United States Environmental Protection Agency, Region 6

(EPA) announces its intent to delete a portion of the French Limited

Superfund Site (Site) from the National Priorities List (NPL) and

requests public comment on this 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), as amended, 42 U.S.C. 9605. This partial

deletion is proposed in accordance with 40 CFR 300.425(e) and the

Notice of Policy Change: Partial Deletion of Sites Listed on the

National Priorities List.

This proposal for partial deletion pertains to all portions of the

Site, excluding shallow groundwater, where appropriate response actions

under CERCLA have been completed (Site Deletion Area). The Site

Deletion Area consists of all properties located within the Site

boundaries but does not include the shallow groundwater beneath the

Site (Excluded Area). The Excluded Area will remain on the NPL and is

not the subject of this partial deletion. CERCLA response activities

will continue in the Excluded Area through 2006, and this partial

deletion will not alter or abate those activities.

This proposal for partial deletion is based on the determination by

EPA and the State of Texas, through the Texas Natural Resource

Conservation Commission (TNRCC), that all appropriate actions under

CERCLA have been implemented to protect human health and the

environment and that no further response action is appropriate in the

Site Deletion Area. In the Site Deletion Area, extensive sampling and

cleanups have been completed at all surface and shallow subsurface

areas that had contaminant levels above the Record of Decision (ROD)

criteria.

Appendix B--Site Coordinate Boundaries--French Limited Superfund Site,

Crosby, Texas

I. Introduction

The EPA Region 6 announces its intent to delete a portion of the

French Limited Superfund Site, Crosby, Harris County, Texas, from the

NPL, which constitutes Appendix B of the NCP, 40 CFR part 300, and

requests comments on this proposal for partial deletion.

This proposal for partial deletion pertains only to the Site

Deletion Area defined herein to consist of all portions of the Site,

excluding shallow groundwater, where CERCLA response activities have

been completed. The Site Deletion Area is the triangular 22.481-acre

tract, including the former eight-acre waste lagoon, located

immediately east of the intersection of, and bounded on two sides by,

old U.S. Highway 90 and Gulf Pump Road near Crosby, Texas.

The Excluded Areas of the Site that will remain on the NPL and are

not the subject of this partial deletion are defined herein to consist

of the shallow aquifer (S1 and INT units) that is undergoing natural

attenuation beneath the Site. CERCLA response activities will continue

in the Excluded Area. The NPL is a list maintained by EPA of sites that

EPA has determined present a significant risk to public health or the

environment. Pursuant to 40 CFR 300.425(e)(3), ``All releases deleted

from the NPL are eligible for further Fund-financed remedial actions

should future conditions warrant such action.''

The EPA will accept comments concerning its intent for partial

deletion for 30 days after publication of this document in the Federal

Register and a newspaper of record.

Section II of this document explains the criteria for deleting

sites from the NPL. Section III discusses procedures that EPA is using

for this action. Section IV discusses the history of the Site and

explains how the Site meets the deletion criteria.

II. NPL Deletion Criteria

The NCP establishes the criteria that EPA uses to delete sites from

the NPL. In accordance with 40 CFR 300.425(e), sites may be deleted

from the NPL where no further response is appropriate to protect public

health or the environment. In making such a determination pursuant to

Sec. 300.425(e), EPA will consider, in consultation with the State,

whether any of the following criteria have been met:

(a) Section 300.425(e)(1)(i): ``Responsible parties or other

persons have implemented all appropriate response actions required;''

(b) Section 300.425(e)(1)(ii): ``All appropriate Fund-financed

response under CERCLA has been implemented, and no further response

action by responsible parties is appropriate; or''

(c) Section 300.425(e)(1)(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.''

A partial deletion of a site from the NPL does not affect or impede

the EPA's ability to conduct CERCLA response activities at areas not

deleted and remaining on the NPL. In addition, deletion of a portion of

a site from the NPL does not affect the liability of responsible

parties or impede agency efforts to recover costs associated with

response efforts.

III. Deletion Procedures

Deletion of a portion of a site from the NPL does not itself

create, alter, or revoke any person's rights or obligations. The NPL is

designed primarily for informational purposes and to assist EPA

management.

Upon determination that at least one of the criteria described in

Sec. 300.425(e) of the NCP has been met, EPA may formally begin

deletion procedures. The following procedures were used for the

intended deletion of the Site Deletion Area from the NPL:

(1) The EPA consulted with the State of Texas on this proposed

partial deletion from the NPL prior to developing this notice of intent

for partial deletion.

(2) The EPA provided the State of Texas at least 30 working days

for review of this notice of intent for partial deletion prior to its

publication in the Federal Register, and the State of Texas, through

the TNRCC, concurred with this proposed partial deletion decision.

(3) Concurrently with publication of this notice of intent for

partial deletion, a document is being published in a newspaper of

record and is being distributed to appropriate federal, state, and

local officials, and other interested parties. Both notices announce a

30 day public comment period concerning this proposed partial deletion,

which commences on the date of publication of this document in the

Federal Register and a newspaper of record.

(4) The EPA has placed copies of information supporting the

proposed partial deletion in the information

[[Page 17595]]

repositories listed above, which information is available for public

inspection and copying. The notice in a newspaper of record also

announces the availability of this notice of intent for partial

deletion. The public is asked to comment on the EPA's proposal to

delete the Site Deletion Area from the NPL. All critical documents

needed to evaluate EPA's decision are listed on the Deletion Docket and

are available for review and copying at the information repositories.

(5) Upon completion of the 30 day public comment period, the EPA

will evaluate the comments and all new data submitted before issuing a

final decision on the proposed partial deletion. The EPA will prepare a

Responsiveness Summary that will address concerns presented by comments

and new data and respond to each significant comment and all

significant new data submitted during the comment period. Such

Responsiveness Summary will be included in the final partial deletion

package. Members of the public are encouraged to contact the EPA to

obtain a copy of the Responsiveness Summary.

(6) If, after review of all public comments, the EPA determines

that the partial deletion from the NPL is appropriate, the EPA will

publish a final notice of final partial deletion in the Federal

Register. The deletion of the Site Deletion Area does not actually

occur until a final notice of partial deletion is published in the

Federal Register. The EPA will place the final partial deletion package

in the information repositories listed above once the final notice of

partial deletion has been published in the Federal Register.

IV. Basis for Intended Partial Site Deletion

The following provides the EPA's rationale for deletion of the Site

Deletion Area from the NPL and EPA's finding that the criterion in 40

CFR 300.425(e)(1)(i) has been satisfied.

Background

The French Limited Site is a 22.5-Sacre tract of land located

adjacent to Highway US-90 in eastern Harris County, Texas, about 20

miles northeast of Houston. The Site is approximately triangular in

shape. The Site is in the floodplain of the San Jacinto River, an area

that was extensively used for sand mining in the 1950s and 1960s.

During the period of 1966 through 1971, the Site was permitted by

the State of Texas to accept industrial waste material. About 80

million gallons of waste material, generated by Houston area

responsible parties, were disposed in the main waste lagoon creating

300,000 cubic yards of contaminated sludges and soils. Some

neutralization was done in 1971 and 1972, and the Site was closed to

receiving wastes in 1973.

The main waste lagoon at the French Site was an abandoned sand pit,

consisting of about eight acres with an average water depth of about 20

to 25 feet. The Site also included a drainage ``slough'' adjacent to

the main pit that periodically received contaminants that were washed

out of the lagoon during flooding events. A shallow aquifer was

contaminated beneath the Site to a depth of approximately 50 feet and

extended laterally offsite approximately 600 feet.

Overview of Regulatory Activities

After Site closure in 1973, a series of regulatory activities

occurred which defined the remedial action objectives and

implementation schedule for the French Limited Site. In 1981 the Site

was listed on the NPL and triggered emergency actions, engineering

studies, and regulatory enforcement actions (including a ROD and a

consent decree (CD)), remedial action construction, and operations. A

chronological summary of these activities is presented in Table 1.

Record of Decision

The components of the selected remedy defined in the Record of

Decision are as follows:

(a) The primary component of the selected remedy for French Limited

is in situ biological treatment of the sludges and contaminated soils

in the lagoon onsite.

(b) The contaminated groundwater will be recovered and treated

during implementation of the in situ biological treatment process.

Groundwater recovery and treatment will continue until modeling shows

that a reduction in the concentration of volatile organics to a level

which attains the 10 -\6\ Human Health Criteria can be

achieved through natural attenuation in 10 years or less.

(c) Surface water from the lagoon will be treated to at least the

Texas surface water quality standards for San Jacinto River Segment

1001.

(d) Residues generated from the treatment process will be

stabilized to prevent leachate generation and used as backfill in the

lagoon. The remaining lagoon volume will be backfilled with clean soil.

The surface will then be graded to promote drainage away from the Site.

(e) The final component of the remedy involves post-closure

monitoring of the upper and lower aquifers for a period of 30 years.

Post-closure monitoring is required under the Resource Conservation and

Recovery Act (RCRA).

Consent Decree

In autumn 1988 and spring 1989, EPA negotiated a consent decree

(CD) with FLTG, Inc. (FLTG) to conduct the remedy established in the

1988 ROD. The CD was effective in March 1990.

The first deliverable by FLTG pursuant to the CD was a remedial

action plan (RAP) that established the design, construction and

operations planning, and schedule requirements to meet the obligations

of the CD. FLTG contracted ENSR Corporation to prepare the RAP and the

subsequent design packages for the remedial action. The final approved

RAP was submitted to EPA in October 1990.

A summary of the implementation of the selected remedy and criteria

for the lagoon, aquifer, and surface water is presented in the

following subsections.

Lagoon

The primary component of the selected remedy for the French Site

was in situ biological treatment of the sludges and contaminated soils

in the lagoon. The concentrations of contaminants in the sludges and

soils were reduced to a 1x10 \5\ excess cancer risk that was tracked by

the compounds and remediation standards shown in Table 2:

* parts per million.

The biomass generated during the biological treatment process was

stabilized in place and the remaining lagoon volume was backfilled with

approximately 15 to 20 feet of clean soil. The surface was graded to

promote drainage away from the Site.

The completion of the lagoon remediation is documented in the Site

Remediation Summary Report: Part A, Lagoon Remediation Verification,

May 1995.

Aquifer/Groundwater

The contaminated groundwater was recovered and treated in an above-

[[Page 17597]]

ground biological treatment facility. FLTG enhanced aquifer and

groundwater remediation with the injection of oxygen and nutrients to

stimulate subsurface in situ biological treatment processes. Active

groundwater recovery and treatment operations continued until computer

modeling showed that aquifer remediation goals could be met through

natural attenuation within 10 years of system shut-off. Aquifer

remediation goals are Maximum Concentration Levels (MCLs) or the 1x10-

6 Human Health Criteria at the Site boundary. The active

aquifer remediation system was shut off in December 1995. The

completion of the active aquifer remediation is documented in the Site

Remediation Summary Report: Part B Active Aquifer Verification, March

1996.

Surface Water

Surface water from the lagoon was treated to at least the Texas

surface water quality standards for San Jacinto River Segment 1001 as

specified in the remedial action plan.

Post-Closure Monitoring

The final component of the remedy involves post-closure monitoring

of the upper and lower aquifers for a period of 30 years. Post-closure

monitoring is required under RCRA. The French Limited Site closure plan

was completed and approved by EPA in March 1996. The post-closure

monitoring, as described in the plan, consists of 10 years of progress

monitoring and 20 years of compliance monitoring. During the progress

monitoring, 13 wells in the S1 unit and 18 wells in the INT unit will

be sampled and analyzed for indicator compounds to evaluate natural

attenuation progress.

During the 20-year compliance monitoring program, six wells in the

S1 unit and eight wells in the INT unit will be sampled and analyzed

for indicator compounds. In addition, several wells will monitor the

gradient inside and outside the lagoon sheet-pile wall.

Community Involvement

The EPA has the lead responsibility for community involvement

activities with TNRCC assistance. Meetings with the surrounding

communities (Riverdale, Crosby, and Barrett Station) were held by both

EPA and FLTG on a periodic basis to explain the ongoing response

actions. The community relations plan was finalized in August 1989.

A community meeting was held at the Crosby High School on February

11, 1988, to present the preferred remedial alternatives as described

in the proposed plan. The public comment period ran from January 25,

1988, through February 23, 1988. Several fact sheets were prepared by

EPA before and after the ROD, administrative order, and CD were signed.

There was a public comment period associated with the lodging of the CD

with the federal court. EPA also issued press releases to local

newspapers and has issued notices that the contents of the

administrative record are available in four designated repositories for

public review and copying. EPA and TNRCC conducted an open house in May

1995, to inform the residents and local officials of the progress

regarding the completion of the remedial actions at the Site. During

the public comment period for this proposed partial deletion, EPA and

TNRCC will conduct an open house meeting in Crosby, Texas, to answer

questions and receive public comments.

In addition to these public meetings and fact sheets, EPA, TNRCC,

and FLTG prepared routine publications of progress, maintained a 24-

hour telephone hot line, participated in community response projects,

conducted group tours and technical seminars, and provided other

community outreach programs.

Site Inspections

Beginning in 1987, EPA and TNRCC conducted monthly inspections of

the Site, which was being cleaned up by the responsible parties. On

February 14, 1996, EPA conducted an inspection of the Site including

the former waste lagoon and aquifer remediation system. EPA determined

that the remedial action performed in the Site Deletion Area was

successful in protecting public health and the environment. Therefore,

except for the Excluded Area, all appropriate response actions have

been completed in the surface and subsurface soils.

Conclusions

In the Excluded Area, a 10-year period of natural attenuation,

following four years of extraction, treatment, and in situ

bioremediation of the shallow aquifer, is part of the 30-year post

closure monitoring as described in the ROD. The active groundwater

remediation operations continued until computer modeling showed that

aquifer remediation goals (as specified in the ROD) could be met

through natural attenuation within 10 years of system shut-off. System

shut-off occurred December 15, 1995. The analysis supporting system

shut down is documented in the Natural Attenuation Modeling Report

dated December 1995.

During the 10-year (or less) natural attenuation phase of

remediation, progress monitoring will be performed at selected

groundwater wells to confirm the computer modeling predictions. FLTG

will continue to collect and analyze groundwater from groundwater

monitoring wells at selected locations at the Site. Upon successful

achievement of aquifer cleanup criteria, EPA will initiate full

deletion of the Site from the NPL and the FLTG will conduct post-

closure monitoring activities for an additional 20 years to ensure

protectiveness of the remedy. Pursuant to the NCP, five-year reviews

will be required for the Site Deletion Area and the Excluded Area. The

first five-year review was performed by EPA in December 1994. Five-year

reviews will be required in years 1999, 2004, 2009, 2014, 2019, and

2024.

All EPA completion requirements for the Site Deletion Area have

been met. Specifically, confirmatory sampling has verified that the

surface and shallow subsurface soils cleanup criteria specified in the

ROD have been achieved at remediated locations within the Site Deletion

Area.

The Site Deletion Area will remain eligible for future Fund-

financed response actions if future conditions warrant such action.

Furthermore, this proposed partial deletion does not alter the status

of the Excluded Area which are is not being deleted and which will

remain on the NPL.

The EPA, with concurrence of the State of Texas, has determined

that all appropriate CERCLA response actions have been completed at the

Site Deletion Area. Therefore, EPA makes this proposal to delete that

portion of the Site from the NPL.
