ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 300
[FRL-6321-6]
National Oil and Hazardous Substances Pollution Contingency Plan;
National Priorities List
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.

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.
