[FRL-8186-7]

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

AGENCY: Environmental Protection Agency.

ACTION: Direct final notice of deletion of the Dixie Oil Processors, 
Inc. Superfund Site from the National Priorities List.

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

SUMMARY: The United States Environmental Protection Agency (EPA) Region 
6 is publishing a direct final notice of deletion of the Dixie Oil 
Processors, Inc. Superfund Site (Site), located in Friendswood, Texas, 
from the National Priorities List (NPL). The NPL, promulgated pursuant 
to section 105 of the Comprehensive Environmental Response, 
Compensation, and Liability Act (CERCLA) of 1980, as amended, is 
appendix B of 40 CFR part 300, which is the National Oil and Hazardous 
Substances Pollution Contingency Plan (NCP). This direct final notice 
of deletion is being published by EPA with the concurrence of the State 
of Texas, through the Texas Commission on Environmental Quality (TCEQ), 
because EPA has determined that all appropriate response actions under 
CERCLA have been completed and, therefore, further remedial action 
pursuant to CERCLA is not appropriate.

DATES: This direct final notice of deletion will be effective August 
21, 2006 unless EPA receives adverse comments by July 24, 2006. If 
adverse comments are received, EPA will publish a timely withdrawal of 
the

[[Page 35811]]

direct final notice of deletion in the Federal Register informing the 
public that the deletion will not take effect.

I. Introduction

    The EPA Region 6 office is publishing this direct final notice of 
deletion of the Dixie Oil Processors, Inc. Superfund Site from the NPL.
    The EPA identifies sites that appear to present a significant risk 
to public health or the environment and maintains the NPL as the list 
of those sites. As described in Sec.  300.425(e)(3) of the NCP, sites 
deleted from the NPL remain eligible for remedial actions if conditions 
at a deleted site warrant such action.
    Because EPA considers this action to be noncontroversial and 
routine, EPA is taking it without prior publication of a notice of 
intent to delete. This action will be effective August 21, 2006 unless 
EPA receives adverse comments by July 24, 2006 on this document. If 
adverse comments are received within the 30-day public comment period 
on this document, EPA will publish a timely withdrawal of this direct 
final notice of deletion before the effective date of the deletion and 
the deletion will not take effect. The EPA will, as appropriate, 
prepare a response to comments and continue with the deletion process 
on the basis of the notice of intent to delete and the comments already 
received. There will be no additional opportunity to comment.
    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 Dixie Oil Processors, Inc. 
Superfund Site and demonstrates how it meets the deletion criteria. 
Section V discusses EPA's action to delete the Site from the NPL unless 
adverse comments are received during the public comment period.

II. NPL Deletion Criteria

    Section 300.425(e) of the NCP provides that releases may be deleted 
from the NPL where no further response is appropriate. In making a 
determination to delete a release from the NPL, EPA shall consider, in 
consultation with the State, whether any of the following criteria have 
been met:
    i. Responsible parties or other persons have implemented all 
appropriate response actions required;
    ii. All appropriate Fund-financed (Hazardous Substance Superfund 
Response Trust Fund) response under CERCLA has been implemented, and no 
further response action 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, 
the taking of remedial measures is not appropriate.
    Even if a site is deleted from the NPL, where hazardous substances, 
pollutants, or contaminants remain at the deleted site above levels 
that allow for unlimited use and unrestricted exposure, CERCLA section 
121(c), 42 U.S.C. 9621(c), requires that a subsequent review of the 
site be conducted at least every five years after the initiation of the 
remedial action at the deleted site to ensure that the action remains 
protective of public health and the environment. If new information 
becomes available which indicates a need for further action, EPA may 
initiate remedial actions. Whenever there is a significant release from 
a site deleted from the NPL, the deleted site may be restored to the 
NPL without application of the hazard ranking system.

III. Deletion Procedures

    The following procedures apply to deletion of the Site:
    (1) The EPA consulted with TCEQ on the deletion of the Site from 
the NPL prior to developing this direct final notice of deletion.
    (2) TCEQ concurred with deletion of the Site from the NPL.
    (3) Concurrently with the publication of this direct final notice 
of deletion, a notice of the availability of the parallel notice of 
intent to delete published today in the ``Proposed Rules'' section of 
the Federal Register is being published in a major local newspaper of 
general circulation at or near the Site and is being distributed to 
appropriate Federal, state, and local government officials and other 
interested parties; the newspaper notice announces the 30-day public 
comment period concerning the notice of intent to delete the Site from 
the NPL.
    (4) The EPA placed copies of documents supporting the deletion in 
the Site information repositories identified above.
    (5) If adverse comments are received within the 30-day public 
comment period on this document, EPA will publish a timely notice of 
withdrawal of this direct final notice of deletion before its effective 
date and will prepare a response to comments and continue with the 
deletion process on the basis of the notice of intent to delete and the 
comments already received.
    Deletion of a site from the NPL does not itself create, alter, or 
revoke any individual's rights or obligations. Deletion of a site from 
the NPL does not in any way alter EPA's right to take enforcement 
actions, as appropriate. The NPL is designed primarily for 
informational purposes and to assist EPA management. Section 
300.425(e)(3) of the NCP states that the deletion of a site from the 
NPL does not preclude eligibility for future response actions, should 
future conditions warrant such actions.

IV. Basis for Site Deletion

    The following information provides EPA's rationale for deleting 
this Site from the NPL.

Site Location

    The Dixie Oil Processors (DOP) Site is located approximately 20 
miles southeast of Houston, Texas, in Harris County. The Site occupies 
approximately 26.6 acres. Portions of the Site occur both north and 
south of Dixie Farm Road and are designated as DOP North and DOP South. 
DOP North covers 19.0 acres and DOP South covers 7.6 acres.
    Mud Gully, a flood control ditch and local tributary of Clear 
Creek, runs along the eastern boundary of DOP North and

[[Page 35812]]

the western boundary of DOP South. The Brio Refining Superfund Site 
borders DOP to the northeast and an abandoned athletic field borders 
DOP North to the southwest.

Site History

    Over the years, several companies conducted operations at the DOP 
site. Intercoastal Chemical Company (ICC) operated a copper recovery 
and hydrocarbon washing facility on the DOP North site from 1969 to 
1978. A total of six surface impoundments were used by ICC to store 
wastewater containing copper prior to recovery and to treat wastewater 
prior to discharge. Wastewaters from the hydrocarbon washing operations 
were also discharged into one of the impoundments. During a two year 
period between 1975 and 1977, the impoundments were closed and 
decommissioned.
    In 1978, DOP began operations on the south side of the site. 
Activities occurring on the site included regeneration of cuprous 
chloride catalyst; hydrocarbon washing to produce ethylbenzene, 
toluene, aromatic solvents, and styrene pitch; oil recovery; and 
blending and distilling residues from local chemical plants and 
refineries (mainly phenolic tank bottom tars and glycol cutter stock) 
to produce various petroleum products including fuel oil, creosote 
extender, and a molybdenum concentrate catalyst.
    Active operations on the DOP site stopped in 1986. Approximately 
6,000 cubic yards of contaminated soils were excavated in 1984 and 
disposed off-site.

Remedial Investigation and Feasibility Study (RI/FS)

    A remedial investigation conducted by the potentially responsible 
parties (PRPs) began at the site in 1986. This investigation identified 
three potential sources of contamination: the contents of drums and 
tanks comprising the process facility, soils associated with the onsite 
waste pits (now closed-out), and contaminated groundwater. The 
investigation found approximately 107,351 cubic yards of contaminated 
soils and subsoils on the site, associated with six different pits. The 
contaminants of concern included ethylbenzene, hexachlorobenzene, and 
copper.
    The risk assessment concluded that the site potentially poses four 
major risks to human health and the environment: ingestion of on-site 
soils, direct contact with on-site soils, inhalation of dust from the 
site, and ingestion of shallow ground water from the site.

Record of Decision

    A Record of Decision (ROD) was issued for the DOP site by the EPA 
on March 31, 1988 selecting limited action and monitoring, including 
fluids stabilization and a site cover with institutional controls. In 
accordance with the requirements of the Unilateral Administrative 
Order, Docket Number 6-23-91, signed by the EPA on July 10, 1991, a 
group of PRPs known as the DOP Task Force was directed to design and 
implement the remedial action as specified in the ROD.

Response Actions

    The remedy was broken into two phases for implementation. The Phase 
I activities included:
     Removal of surface contamination;
     Improvement of surface water controls;
     Reconstruction of Mud Gully;
     Revegetation and installation of security fencing.

Phase II activities included:
     Removal and off-site disposal of tank residuals;
     Dismantlement of the process tanks and drums;
     Disposal of process equipment.
    Phase I field activities began on March 26, 1992. Surficial 
deposits of contamination were removed, stored in roll-off containers 
and sent off-site for disposal. Approximately 1750 tons of contaminated 
soils and sludges from storage tanks were sent off-site for disposal. 
All off-site facilities were in compliance with EPA's Off-Site Disposal 
Policy.
    Phase II activities began in August 1992. This phase entailed 
removal of liquids and sludges stored in process vessels left on the 
site. Approximately 250,000 gallons of material were removed from the 
vessels and sent off-site for disposal. The vessels were removed and 
sent to a smelting facility.
    The DOP Task Force notified EPA that Phase I and Phase II 
activities were completed on March 27, 1993. A pre-certification 
inspection was conducted by EPA on April 20, 1993. The DOP Task Force 
certified that the Remedial Action was complete in a letter dated April 
27, 1993. The DOP Task Force prepared a Remedial Action Report that 
contained a certification by a Texas Professional Engineer that all the 
requirements of the Remedial Design were met. EPA approved the report 
on August 6, 1993.

Operation and Maintenance (O&M)

    In July 1993, the DOP Task Force submitted a Monitoring, Operation 
and Maintenance (MO&M) Plan for the DOP site. The plan was revised in 
January 1999. The purpose of the MO&M Plan is to document procedures to 
be used to assess the long-term success of the site remedy while 
minimizing adverse natural or man-made impacts on the DOP site. The 
plan requires (i) monthly inspections and maintenance, (ii) a five-year 
review as required by the EPA, and (iii) semi-annual monitoring of the 
environmental media (soil, ground water, and air).
    The DOP Task Force conducts monthly site inspections to identify 
any damage to the site facilities, and monitors the general health and 
integrity of the soil cover.
    Since monitoring began in May 1993, the DOP Task Force has kept 
records of site activities and submitted them to the EPA on an annual 
basis. The reports include specific maintenance activities completed 
during the past year, dates that maintenance activities were performed, 
names of people and companies performing the maintenance activities, 
and any replacements or redesigns of deficient materials or equipment.
    The institutional control plan for the Site was revised in February 
2006 and included deed restrictions filed by the landowner in 2005. The 
deed restrictions provide long-term assurance of the protectiveness of 
the remedy by limiting the future uses of the site.

Five-Year Review

    Consistent with section 121(c) of CERCLA and requirements of the 
OSWER Directive 9355.7-03B-P (``Comprehensive Five-Year Review 
Guidance'', June 2001), a five-year review is required at the Site. The 
Directive requires EPA to conduct statutory five-year reviews at sites 
where, upon attainment of ROD cleanup levels, hazardous substances 
remaining within restricted areas onsite do not allow unlimited use of 
the entire site.
    Since hazardous substances remain onsite, this Site is subject to 
five-year reviews to ensure the continued protectiveness of the remedy. 
Based on the five-year results, EPA will determine whether human health 
and the environment continues to be adequately protected by the 
implemented remedy. Five-year reviews were completed on September 24, 
1998 and September 4, 2003. The reviews found that the remedy remains 
protective of human health and the environment. The MO&M plan was 
revised in January 1999, and continues to be implemented by the DOP 
Task Force to ensure the remedy remains protective.

Community Involvement

    Public participation activities have been satisfied as required in 
CERCLA section 113(k), 42 U.S.C. 9613(k), and CERCLA section 117, 42 
U.S.C. 9617. Documents in the deletion docket which EPA relied on for 
recommendation of the deletion from the NPL are available to the public 
in the information repositories.

V. Deletion Action

    The EPA, with concurrence of the State of Texas, has determined 
that all appropriate responses under CERCLA have been completed, and 
that no further response actions under CERCLA, other than O&M and five-
year reviews, are necessary. Therefore, EPA is deleting the Site from 
the NPL.
    Because EPA considers this action to be noncontroversial and 
routine, EPA is taking it without prior publication. This action will 
be effective August 21, 2006 unless EPA receives adverse comments by 
July 24, 2006. If adverse comments are received within the 30-day 
public comment period, EPA will publish a timely withdrawal of this 
direct final notice of deletion before the effective date of the 
deletion and it will not take effect. The EPA will prepare a response 
to comments and continue with the deletion process on the basis of the 
notice of intent to delete and the comments already received. There 
will be no additional opportunity to comment.
