The Malone Services Company (MSC) Site is located in Galveston county,
Texas City, Texas, at 5300 Campbell Bayou Road. The site is located in an
industrial and petrochemical area, on the shores of Swan Lake and Galveston
Bay, approximately 1.6 miles southeast of the intersection of Loop 197 and
State Highway 3.
The Site is located in a marsh/wetlands area, and approximately 1.5 miles from
the nearest residential area. An estimated 10,000 people live and/or work
within a three-mile radius of the site.
Setting: The MSC was a reclamation, storage and disposal facility for waste oils and
chemicals that included acid and caustic compounds, solvents, and gasoline and
crude oil tank bottoms.
The MSC site covers approximately 150 acres. Approximately 100 acres
(northeastern portion of the Site) of the 150 acre site were developed for the
storage, processing and disposal of industrial hazardous wastes. The developed
acreage contains numerous waste handling areas; which include storage tanks,
2 API separators, a ±5 acre settling pond, a closed ±0.5 acre waste collection
pond, and two(2) deep subsurface injection wells. The remaining undeveloped
50 acres (northwestern portion of the Site) contain a ±7 acre storm water
The entire facility is encircled by an 18 foot high flood control levee. Wetlands,
Galveston Bay and Swan Lake border the northeast and east sides of the site.
Industrial and waste disposal facilities are located outside the northwestern and
western boundaries of the Site. The southwestern, southern and southeastern
boundaries of the facility border on marsh land/wetlands.
Within the Site boundary, two shallow channel sands merge into one channel
sand to form the primary aquifer of concern below the site. Due to its shallow
nature and its high chloride and Total Dissolved Solids (TDS) content, this
aquifer is not a drinking water source. The channel sands trend northwest to

southeast, and merge midpoint within the facility. Ground water flow appears
to be northwest to southeast, into Galveston Bay.
The waste water settling pond, the waste collection pond and the stormwater
pond were excavated through the shallow channel sand aquifer and into the
underlying clay layer, and therefore, the wastewater ponds supply/supplied
contaminants to the shallow ground water.
In addition to the stormwater pond, which collects the majority of runoff within
the northwestern portion of the facility, several areas on the western and
southwestern portions of the Site collect the remaining surface water runoff.
Following testing, this stormwater is either discharged into Galveston Bay or
deep well injected.
The Chicot Aquifer, which is a primary drinking water aquifer at depth,
underlies the site from approximately 100 feet to 1100 feet below ground
Wastes and Volumes
The principal contaminants of concern at this site are the myriad of organic and inorganic
chemical wastes in the form of liquids, sludges and solids present in the above ground storage
tanks, the API separators, the settling pond, and the surface soils of some of the secondary
containment areas on the site.
Wastes received at the facility included acids and caustics from industrial cleaning and surface
preparations; contaminated residues and solvents removed from processing and storage units
during cleaning operations; spent drilling fluids, including drilling muds and brines, from well
workover and exploration activities; acids containing metals from etching and plating
operations; inorganic slurries from sump cleaning; gasoline and crude oil tank bottoms;
contaminated earth and water from chemical spill cleanup operations; general industrial plant
wastes; phenolic tars; and waste oils.
The groundwater pathway appears to be the only ongoing active release of hazardous
substances occurring at the Site. The settling pond is located within a sand channel. The limits
of the pond on the north and south appear to coincide with the approximate limits of the sand
channel; the east and west ends are exposed to the sand channel. The operator had indicated
the east and west ends of the pond had been sealed with clay, apparently to prevent
contaminants from entering the ground water. However, ground water and pond constituent
characterization indicate that the sand channel has been impacted by the ponds.
Ground water samples collected during a 1997 Texas
atural Resource Conservation
Commission (TNRCC)(now the Texas Commission on Environmental Quality (TCEQ)
inspection indicated that hazardous substances originally found in the impoundment and API
separator in the 1980's field sampling had been released to the underlying aquifer. Chemical
analysis of Galveston Bay sediments (adjacent to the Site) determined the presence of
chromium and lead; it has yet to be determined if this is related to the Site.
Presently, volumes of materials to be remediated have not been determined; however, volumes
will be determined during the Remedial Investigation (RI)/Feasibility Study (FS).

Site Map and Diagram
The Remediation Process
The Site consists of buildings, approximately 83 holding/storage/blending tanks, two API
separators, one hazardous waste pond (and one which was recently closed), a stormwater pond,
and a rainwater runoff collection and discharge area.
The facility operated from 1964 until 1997. MSC was originally permitted as a waste oil
reclamation facility, but later added hazardous waste underground injection/disposal wells.
Wastes were received by the facility from a variety of industries. Wastes from the reclamation
process were disposed down the onsite deep injection wells.
The original operation, which began in 1964, consisted of two earthen unlined pits which
received incoming wastes. The larger pit, which served as a settling pond, was used for wastes
with high solids and /or water content. The oil fraction would rise to the surface of the large pit

where it was skimmed off and pumped to a smaller oil pit (which is closed). Oils in the oil pit
were then pumped to one of several tanks for treatment. The oil was then resold as waste oil
for energy recovery.
API separators were installed in 1979 and 1987 to replace the settling pond and oil pit; however
the pond and pit were never cleaned/removed, hazardous liquid wastes and solids still remain in
the open large pit and closed small oil pit. Oils separated in the two API units were pumped to
holding/treatment tanks; waste water was pumped to the injection wells for disposal and the
solids were sent to an offsite hazardous waste landfill for disposal.
Surface drainage directs rainwater runoff on the developed acreage to one collection point
within the Site; runoff on the undeveloped acreage is collected in the southwest stormwater
pond. In the past, this collected runoff from within the Site was analyzed and discharged to
Galveston Bay or injected dependent on analytical results. Presently, this runoff is managed as
it was in the past.
Ground water sampling results indicate that ground water has been impacted by hazardous
wastes in the area of the inactive five acre impoundment and the 100 Unit Separator.
EPA Removal conducted removal actions at the Site from 1999 to 2000.
The Site was listed to the
PL on June 14, 2001.
atural Resource Conservation Commission contractors conducted periodic inspections
of stormwater controls at the site and maintained stormwater capacity in ponds and separators
at the site. This responsibility has been assumed by EPA Removal. Stormwater runoff is
directed to one collection point within the Site, analyzed, and dependent on analytical results,
discharged to Galveston Bay or injected into the onsite deep injection/disposal well.
EPA issued General
otice Letters to major generators (those who contributed 0.6% or greater
of total waste delivered to the Site) and the current owner.Several of the Potentially
Responsible Parties (PRPs) have formed a steering committee (the Malone Cooperating Parties
(MCP)) and have signed the Administrative Order on Consent (AOC) to conduct the Remedial
Investigation and the Feasibility Study (RI/FS).
The MCP have assume Site storm water management activities from EPA Region 6.
EPA Region 6 approved the Remedial Investigation Feasibility Study Work Plan for the Site
on June 29, 2005. Mobilization to the site to conduct the investigation to determine risk and
nature and extent of contamination was conducted in mid July. Field work to collect
ground/surface water, soils, sediment and sludge samples is on-going and is scheduled to be
completed the end of September.
o Public Informational Meetings will be held until
sufficient information is available to answer possible community concerns, which would most
probably be in 2006.
Site contaminants have been found in ground water below the site. Constituents related to the
site have beenfound in Galveston Bay sediments. Hazardous constituents may exist in surface
water runoff. The Remedial Investigation/Feasibility Study will be conducted to determine the
extent of contamination at and below the surface of this Site and Galveston Bay.

Present Status and Issues
EPA and the PRPs are presently working on amending the AOC to incorporate the recently
approved Statement of Work for storm water management at the Site.
Following the completion of the Remedial Investigation/Feasibility Study and a baseline risk
assessment, a Proposed Plan will provide the Agency's proposed remedial action for the site.
The remedial action decided upon will be presented in a Record of Decision (ROD) following
public meetings and public comment. The ROD will present the cleanup measures determined
to be protective of human health and the environment.
