16. Abstract (Limit: 200 words)
The Stewco site, previously a tanker truck terminal and truck washing
facility, is located in northeastern Texas, in Eastern Harrison County,
south of the city limits of Waskom. The site consists of two nonadjacent
locations approximately one mile apart, referred to as Location 1 and
Location 2. Location 1 is a one-half acre plot that includes a maintenance
hop with fueling facilities, a truck-tank washing facility, and two
ackfilled and capped evaporation ponds (ponds 1 and 2) that received
astewater from the tank washing operation. Approximately 50 homes are
located within one-half mile of Location 1, four of these are within 500
feet of the north, west and south site boundaries. In addition, shallow
wells are located approximately one mile to the north. Location 2 consists
of a third pond which received excess wastewater conveyed by truck from the
evaporation ponds at Location 1. Approximately 30 homes are within a
one-half mile radius of Location 2. Land use within a one mile radius of
the two locations includes residential, recreation, industrial, and
commercial. The underlying Wilcox aquifer serves the city of Waskom as well
as numerous domestic users within a three mile radius of the site. From
1972 - 1979, R.A. Corbett Transport, Inc. owned, operated and maintained a

6. ABSTRACT (continued)
fleet of transport trucks engaged in contract hauling for the oil and gas
industry and various businesses. Stewco purchased the site in 1979 and
continued operations until declaring bankruptcy in 1983. Materials hauled
included glue, resin, gasoline, diesel, jet fuel, and creosote. The
wastewater generated from washing the outside of trucks, and the tank
residue resulting from steam cleaning the inside of the tankers were
directed to pond 1 with overflow entering pond 2, and the surplus
transported to the third pond at Location 2. All ponds were unlined.
Reports from the Texas Water Commission files indicate numerous instances
of noncompliance with permit requirements. After abandonment in 1983, ponds
1 and 2 began to overflow their dikes creating a serious threat of dike
collapse and significant hazardous substances release. Consequently, EPA
conducted a removal action at Location 1 from March 31 to April 14, 1984.
The action consisted of removing the source of contamination: 400,000
gallons of liquid wastes were pumped, treated, and discharged; and 5,500
yd3 of sludges from the bottom and sides of the disposal ponds were
stabilized and disposed of offsite. The pond disposal area was then
backfilled and capped. No removal or remedial actions were taken at
Location 2 since the level of contamination was much less than that of
Location 1 and the pond was not filled near capacity. The contaminants of
concern prior to the removal action were VOCs, PAHs, and phthalates.
EPA determined that, based on the effectiveness of the previous removal
ction, the residual contamination remaining in the soil, pond sediments,
land ground water poses no threat to public health, and that no long-term
monitoring is necessary. Therefore, no further action will be taken at
this site. However, ground water contamination has been identified that is
not attributed to the site. Follow-up actions by the State and EPA will
attempt to determine the source of this contamination. If within 2 years
of the signing of this ROD, wells onsite at Stewco are determined to be of
no use to the offsite source investigation, closure will be initiated. The
cost of plugging the 16 wells is estimated not to exceed $5,000.
PERFORMANCE STANDARDS OR GOALS: Chemical-specific goals met by this no
action remedy were not specified.
INSTITUTIONAL CONTROLS: Not applicable.
KEYWORDS: No Action Remedy.

RECORD OF DECISION
September, 1988
SITE NAME AND LOCATION
Stewco, Incorporated is located in Waskom, Harrison County, Texas.
STATEMENT OF PURPOSE
This decision document represents the rationale for determining that no
further remedial action is warranted under Superfund for the Stewco site.
This decision is in accordance with the Comprehensive Environmental
Response, Compensation, and Liability Act of 1980 (CERCLA) as amended by
the Superfund Amendments and Reauthorization Act of 1986 (SARA), and the
National Contingency Plan (40 CFR Part 300).
STATEMENT OF BASIS
This decision is based upon the administrative record for the Stewco,
Incorporated Superfund Site. The attached index (Appendix A) identifies
the items which comprise the administrative record.
Based upon the findings in the Remedial Investigation for this site, the
residual contamination remaining in subsurface soils, pond sediments, and
groundwater (following the 1984 Emergency Response Action) pose no public
health threats. However, groundwater contamination has been identified
that is not attributed to the site. Although the groundwater is a potential
drinking water source, Class II B Aquifer, no private wells are located
immediately downgradient of the site at this time. Follow-up actions by
other programs within both the State and EPA will attempt to determine
the source of this contamination.
The Agency for Toxic Substances and Disease Registry (ATSDR) has been
consulted and supports this conclusion.

DESCRIPTION OF SELECTED REMEDIAL ACTION
o Based on the completeness of the previous removal action, no further
remediation is necessary for the Stewco site. Although long-term
monitoring is not required, groundwater wells will not be closed out
at this time. If the wells can be of no use to the off-site source
investigations during the following two years, then closure will be
initiated.
o Potential off-site and/or active facilities which appear to be
contributing to groundwater contamination in the area of the site
will be further investigated by other programs within both the
State and EPA.
o If new information from the off-site source investigations correlate
with the current findings, that site residuals are not contributing
to groundwater volatiles contamination, then deletion of the site
from the National Priorities List will be pursued.
DECLARATION
Consistent with the Comprehensive Environmental Response, Compensation,
and Liability Act of 1980 as amended by the Superfund Amendments and
Reauthorization Act of 1986, and the National Contingency Plan, I have
determined that this decision will provide adequate protection of the
public health, welfare, and the environment. This decision attains
Federal and State requirements that are applicable, or relevant and
appropriate. In view of the 1984 source removal and based upon the
lack of significant risks posed by the site, this decision is permanent
and cost effective. Alternative treatment technologies were used to
the maximum extent practicable during the source removal. Because
no site related hazardous substances remain onsite above health based
levels, the five-year facility review will not apply to Stereo.
The State of Texas has been consulted and supports this remedial
decision for the Stewco, Incorporated Superfund Site. If new information
obtained from the off-site investigations do not correlate with the
current findings, the need for groundwater remediation will be evaluated.
For such case, a Record of Decision will be prepared to address any
future remedial action(s).

July, 1988
SITE LOCATION AND DESCRIPTION
The Stewco Site, previously a tanker truck terminal and truck washing
facility, is located in Eastern Harrison County, south of the city limits
of Waskom, Texas. Harrison County is located in northeastern Texas and
the eastern county line borders the State of Louisiana. The site consists
of two non-adjacent locations approximately one mile apart, referred to
as Location 1 and Location 2. The two locations of the Stewco site are
presented in Figure 1.
Location 1
Location 1 is a one-half acre plot on the east side of State Highway 9,
approximately one-half mile south of the intersection of State Highway 9
and Interstate 20. Location 1 has an office and maintenance shop with
fueling facilities, a truck-tank washing facility, and two backfilled and
capped evaporation ponds that received wastewater from the tank washing
operation prior to remedial actions. Pond 1 was 75 by 75 feet in plan by
10 feet deep, while Pond 2 was 85 by 55 feet in plan by 15 feet deep.
The Location 1 site boundary includes the area surrounding the backfilled
ponds and truck wash pad, as outlined on Figure 2.
Approximately 50 homes are located within one-half mile of Location 1.
Four of these residences are within 500 feet of the north, west, and south
site boundaries. Currently, an active gas well, oil and water separator,
and associated salt-water gathering line'are located immediately northwest
of the "cap" area. A petroleum tank farm, the Mobil Oil Corporation-Waskom
Terminal borders the site on the east. The Mobil facility consists of
numerous large petroleum storage tanks and a pond immediately adjacent to
the east boundary. The Texaco facility, also a petroleum storage terminal,
borders Mobil on the north, northeast of the Stewco site.
Location 2
Location 2 consists of a third pond, approximately 1/4 acre in size,
which received excess wastewater conveyed by truck from the evaporation
ponds at Location 1. Location 2 is located approximately one mile
northwest of Location 1 and about 100 yards south of Interstate 20. The
pond is partially above ground and is approximately 165 feet by 60 feet
in plan and 10 feet deep. The boundary of the study area for this
location is limited to the pond, dike and immediate surrounding area.
Location 2 has no adjoining residences within 500 feet. Approximately 30
homes exists within one-half mile. The only structures adjacent to
Location 2 are two storage tanks which hold oil and condensate from a gas
production well located immediately west of the evaporation pond. The
tanks are located about 40 feet south of the pond. The general layout of
Location 2 is shown on Figure 3. The remaining land immediately surrounding
Location 2 is undeveloped forest land.

Site History
From 1972 to 1979 R.A. Corbett Transport, Incorporated owned, operated
and maintained a fleet of transport trucks engaged in contract hauling
for the oil and gas industry and other businesses in the Waskom area.
Materials hauled included glue, resin, gasoline, diesel, jet fuel and
creosote. In July, 1979 R. A. Corbett Transport, Incorporated sold its
interstate operating authority and terminal facilities to the Stewco,
Incorporated Company which continued operations until declaring bankruptcy
in 1983.
During active operation, wastewater was generated from high pressure
washing of the outside of trucks and from steam cleaning the inside of
tankers. An alkaline cleaning solution was used, making it necessary
to neutralize the wastewater with acid. Wastewater and tank residue
were directed to Pond 1 (154,000 gallon capacity) with overflow entering
Pond 2 (270,000 gallon capacity). Surplus wastewater from these unlined
ponds was trucked to a third pond (Location 2) approximately one mile
away.
Field inspection reports and other correspondence concerning the site,
available in the Texas Water Commission (TWC) files, formerly the Texas
Department of Water Resources (TDWR), indicate numerous instances of
noncompliance with permit requirements at Location 1. Violations
included unauthorized surface discharges, degeneration of groundwater
quality, inadequate freeboard, and inadequate operation of acid treatment
mechanisms. TDWR recommended site remedial actions including the dewatering
and proper disposal of evaporation pond contents and the implementation
of a groundwater quality improvement program. Stewco, Inc. filed for
Chapter 7 bankruptcy on May 6, 1983, with inadequate assets to conduct
remedial activities. Site remedial actions recommended by the TDWR were
not implemented.
Both locations were abandoned in early 1983 and the ponds continued to
collect rainfall. Ponds 1 and 2 at Location 1 became full after site
abandonment with a slight amount of water overflowing the dikes. This
created a serious threat of dike collapse which could result in a substantial
release of hazardous waste. Inspection of the site by the EPA Field
Investigation Team (FIT) in November, 1983, recommended that EPA undertake
removal actions.
An immediate removal action was conducted by EPA at Location 1 from
March 31 to April 14, 1984. The action consisted of removing the source
of contamination: 400,000 gallons of liquid wastes were pumped, treated,
and discharged; 5,500 cubic yards of sludges from the bottom and sides of
the disposal ponds were stabilized and trucked to the Chemical Waste
Management Company Class A landfill at Port Arthur, Texas about 202 miles
away. The pond disposal area was then backfilled with clean soil and a
10-mil plastic liner was placed across the area. Over the liner, two
feet of compacted soil was then graded to the original site slope and
seeded with bermuda grass.
No removal or remedial actions were taken at Location 2 since the level
of contamination was much less than that at Location 1 and the pond was
only 45% full with no evidence of dike failure.
-------
The Stewco site, both locations, was ranked using the EPA Hazardous Ranking
System in June, 1984. Although Location 1 had undergone an immediate
removal action, the ranking was performed as if the removal never occurred.
The site scored a 48.86 based on the potential groundwater route to the
Wilcox Aquifer, which serves the City of Waskom, Texas, as well as numerous
domestic users within a three mile radius of the site. At the time of
ranking the constituents of concern were polynuclear aromatic hydrocarbons,
phthalates, DDT, and aromatic solvents.
On November 13, 1987, the EPA committed funds to perform a Remedial Invest-
igation at the site. Enforcement options were not available, although
potentially responsible parties were notified. The Remedial Investigation
fieldwork was completed in February, 1988. The results of this study
were documented in the Remedial Investigation Report, completed in draft
form in May 1988, and will be discussed in the remainder of the Decision
Summary.
LAND USE AND NATURAL RESOURCES
Land use within a 1 mile radius of the two Stewco locations includes
residential, recreational, industrial, and commercial. Natural resources
in the vicinity of the site include groundwater, surface water, fish and
game, arable land, forest woodlands, minerals, and oil and gas resources.
The local economy is based on petroleum production, mining, timber
production, cattle raising, and cotton production.
The corporate city limits of Waskom are located within a 1 mile radius
of both Stewco locations as depicted on Figure 1. According to the 1980
census, the population of Harrison County is approximately 53,000. The
city of Waskom is estimated at having a current population of about 2,000.
Additional population not residing within the corporate limits of Waskom,
but 3 miles of the Stewco locations, has been estimated at 1,300. The
total number of people within a 3 mile radius of the site is approximately
3,300.
The area surrounding and on the Stewco site locations is suitable habitat
for game and non-game species of wildlife. The study area can be
generally characterized as rolling to hilly topography within the pine-
hardwood section of the East Texas timber belt. The area has been heavily
developed for oil and gas production and several oil and gas wells, pumping
stations, and storage tanks are in close proximity to both Stewco locations.
Geology
The Stewco site is situated on the eastern edge of the East Texas Basin, a
15,000 square-mile area that is part of the Gulf Coastal Plain. The
region is characterized by thick sediments, low-amplitude crustal warping,
and some structural deformation. A broad upwarp, the Sabine Uplift,
occurs beneath the Waskom area. Topography is mildly undulating, with
surface elevations varying from 260 to 300 ft above Mean Sea Level (MSL).
The East Texas basin was formed by block faulting, and is filled with
thick accumulations of consolidated and unconsolidated sediments, ranging
from Jurassic to Tertiary in age. The strata include halite evaporate
units which have produced salt domes in the center of the basin, 50 miles
to the west of the site. As shown in Figure 4, strata outcropping in the

vicinity of the site belong to the Eocene Wilcox Group, which is composed
of interbedded sand, silt, clay, shale, and lignite. The Wilcox Group is
approximately 400 feet thick and is underlain by the finegrained Midway
Group.
The distinction between consolidated and unconsolidated materials becomes
uncertain due to overconsolidation of some sediments. The discontinuous
nature of the strata and the distance between the two site locations
requires separate characterization of Location 1 and Location 2, each
having a distinctly different near surface geologyand hydrogeology.
Figure 5 represents the subsurface at Location 1 and Figure 6 repre-
sents the subsurface at Location 2, as determined from the boring and
well logs at each location during the Remedial Investigation fieldwork,
February 1988. These figures will be discussed in the following section.
Hydrogeology
Regionally, the Wilcox Group is considered as a single aquifer for water
supply purposes, even though it is stratified and heterogeneous. When
considered as a single hydrologic unit, the Wilcox has an average
transmissivity of 3,150 gpd/ft and an average hydraulic conductivity of
52 gpd/ft . The transmissivity is variable, depending on the relative
proportion of sand to clay in the stratigraphic section. The direction
of groundwater flow is related to surface topography, but is generally
eastward or northeastward in east-central Harrison County. The native
groundwater is a sodium bicarbonate type.
As the source of groundwater to the Waskom municipality, the Wilcox
serves six pumping wells at an average daily pumping rate of between 250,000
and 300,000 gallons per day. The radius of influence for the pumping
wells is not known. Both site locations are within the distribution area
for municipal water. Shallow wells are located approximately 1 mile
north of Location 1. A rural water authority serves the zone outside of
the Waskom service area.
For site assessment purposes, the individual sand bodies within the Wilcox
are considered separate aquifers. Again in reference to Figures 5 and 6,
the first significant water bearing zone beneath each location differs in
composition. In general, values in hydraulic conductivity in the near-surface
saturated zone (both locations) are low to moderate.
Along the southern site boundary at Location 1, the near-surface aquifer
extends from 9 feet down past 50 feet beneath the surface [Units B and D],
Figure 5. On the northern portion of the site, the aquifer is separated
into two zones by an aquitard [Unit C] which decreases in thickness from
13 feet to 0 feet [where Unit B and D form a single unconfined aquifer].
Groundwater flows beneath the site in a southwestward direction at an
average rate of.05 foot/day.

At Location 2, the near-surface aquifer [Unit F] extends from about 6 feet
down to 30 feet beneath the surface, Figure 6. A fine grained clay [Unit
G.Ga] underlies this aquifer. On the north side of the pond, the surficial
clay layer [Unit E] is less than 2 feet thick. Since the depth of the
pond is 7 feet and the depth to the water table is generally 5 feet, the
pond has become an integral part of the shallow groundwater system.
Although the near surface groundwater flow beneath the site is generally
to the east, flow from the pond is radial on the north, east, and south
sides. The groundwater average flow velocity is .07 foot/day on the north
and south sides of the pond and .2 foot/day on the east.
Private wells present in the area, Figure 7, are upgradient of both site
locations (near-surface groundwater flow direction). These wells are
probably completed in the Wilcox aquifer, although data in well construction
were generally unavailable. The nearest domestic water well to either
site location is at the J. B. Rudd residence, about 1850 feet northeast
of Location 1.
Surface Water Hydrology
The surface water hydrology differs at each site location, but is primarily
controlled by the slope and intervening terrain. Runoff from each site
location into definite drainage pathways may be limited by the length of
overland flow, therefore increasing the amount of precipitation infiltration
into the ground surface.
At Location 1 the precipitation drains to the south from the cap area
into a pasture where a natural spring and its drainage are intercepted,
then to an unnamed tributary which flows into Crosrs Bayou. Site drainage
from the main building area flows west along a fence line into a north-
south drainage ditch adjacent to Highway 9 and then flows south to an
unnamed tributary and then to Cross Bayou. The ponding of surface water
runoff at Location 1 occurs in the southwest^corner of the site, but most
runoff will enter one of the two drainage pathways or infiltrate the soil
prior to reaching either drainage pathway.
Surface water runoff at Location 2 drains to the north of the site in
small drainage ditches to an east-west drainage area adjacent to the
Interstate 20 service road. The length of overland flow limits the
amount of runoff that may reach other surface water drainage patterns.
If runoff does continue to flow from the service road drainage area, the
runoff would enter an unnamed intermittent stream east of the site, then
an unnamed tributary of Cross Bayou, then Cross Bayou. Runoff may also
flow into an unnamed intermittent stream, then to an unnamed tributary,
then to Cross Bayou. Surface water ponding at Location 2 is present and
surface water runoff may be minimal as evidenced by the onsite ponding of
water. Water collects in an onsite pond, in a low-lying area northeast
of the pond, in a seepage area southeast of the pond, and in the areas
east and south of the pond where the onsite gravel road is higher than
the base of the pond's berms.
Cross Bayou flows across the Texas/Louisiana state line into Cross Lake,
then back into Cross Bayou, which flows into the Red River. Cross Bayou
is designated by the Louisiana Stream Control Commission to have water
use for primary and secondary contact recreation, for propagation of fish
and wildlife, and for domestic raw water supply.

REMEDIAL INVESTIGATION RESULTS
The primary objectives of the Remedial Investigation were to acquire site-
specific data needed to document the existence of hazardous substances
and threats of releases of hazardous substances at the Stewco site. The
Remedial Investigation focused on determining background conditions and
the presence/absence and extent of contamination in various environmental
media at each location of the Stewco site. From the information obtained
during fieldwork activities (February 1988), the potential for future
migration of contaminants was then evaluated. The site specific geology
and hydrogeology were presented in the previous section.
In order to evaluate the effect of site contaminants on public health and
the environment, contaminants of concern are selected by assessing their
toxicity, concentration, and persistence. Health criteria have been
developed for various chemicals in surface water and groundwater. However,
since health criteria have not been developed for contaminants in soil
and many chemicals are either naturally occurring in the environment or
have resulted as part of common industrial activities, "background" concen-
trations are used for comparative purposes. In the absence of health
criteria or background information, toxicity information is used to
quantify risks associated with a chemical. In the absence of toxicity
information, a chemical of potential concern is retained for qualitative
evaluation in the risk assessment.
Tables 1 and 2 summarize the primary chemicals of concern for each media
at Location 1 and at Location 2, respectively. Tables 3 and 4 compare
those chemicals with available Applicable or Relevant and Appropriate
Requirements (ARAR). For groundwater which is a potential drinking water
source, Maximum Contaminant Level (MCL) concentrations are health based
criteria set for maintaining groundwater quality. These same criteria
may be used for the pond at Location 2 due to its interaction with the
groundwater. In the absence of MCLs, Ambient Water Quality Criteria
(AWCQ) are used for comparative purposes.
However, the origin of contamination at any site must also be evaluated to
distinguish between those chemicals resulting from past site operations
and those chemicals resulting from other sources in the site vicinity.
All chemicals of concern, whether site related or non-site related, were
evaluated in the Risk Assessment. Any such chemicals will be identified
and discussed in the following subparts.

Location 1
Soils Investigation
Numerous polycyclic aromatic hydrocarbons (PAHs) were detected in the soils
at Location 1. Those PAHs detected at Stewco are persistent and relatively
immobile in the soil at the site. Although PAHs in the subsurface can be
assumed to represent residual contamination remaining 'in the soils following
the Emergency Removal Action in 1984, some surface soils in the cap area
contain higher levels of certain PAHs. The concentration levels detected
are within the expected background concentrations for this area of Texas,
and in consideration of the surrounding industry.
Some inorganics in surface soils at Location 1 were elevated in comparison to
surface soils in the site vicinity. However, no health effects are anticipated
from these contaminants, as assessed in the risk analysis. Inorganics detected
in subsurface soils at Location 1 were within expected background ranges for
Northeast Texas.
Other organics were detected infrequently in the subsurface. These include
pesticides and the volatile organics benzene, ethylbenzene, and xylene.
The three pesticides detected were within expected background concentrations.
Ethylbenzene was previously (1983 FIT investigation) detected in the original
Pond 1 sediments, but at concentrations orders of magnitude higher than
current data. Benzene and xylene were not detected in the original pond
sediments during the 1983 FIT investigation or in the 1984 post-removal
sampling by Emergency Response. A subsurface investigation report (1986)
by a neighboring facility show these same substances to the east of the
site in an area which should not be affected by Stewco past operations.
Surface Hater and Sediments
Eleven organics were detected at relatively low concentrations and
frequencies of detection. No significant organic or inorganic contamination
were present in these samples.
Groundwater
PAH compounds found at concentrations above detection limits include
acenaphthene, dibenzofuran, fluorene, and phenanthrene. These compounds are
heavier than water and were detected only at low levels in the deep downgradient
well at the southwest corner of the site [MW-4D]. None of the PAHs detected
in the groundwater are believed to be carcinogenic (cancer causing). Although
dibenzofuran is not currently classified as either a carcinogen or noncarcinogen,
the low level detected should not present an adverse health risk if exposure
to groundwater were to occur.
The only metal which was detected in higher concentrations downgradient
than upgradient was aluminum, which was detected in both the shallow and
deep wells at the southwest corner of the cap area [MW-4S.MW-4D] at'concen-
trations of 199 and 279 ug/1, respectively. Although health criteria for
this inorganic have not been developed, potential risk of health effects would
be minimal if exposure were to occur. The other metals did not exhibit flow-
related concentrations.
18
-------
Off-gradient well samples at the northwest and southeast corners of the site
were not influenced by residual PAHs beneath the cap area since the near-
surface groundwater flows from the northeast to the southwest. However,
volatile organics and metals were detected which have been determined to
not be contributed by residuals from the former ponds. Although benzene
and 1,2-dichloroethane and barium exceed MCLs, their pattern of occurrence
and concentration would indicate that the site is not the source of these
substances. Two other factors support this conclusion:
1) None of the volatiles or metal of concern were among
those contaminants of significant magnitude which were
detected in the 1983 FIT investigation.
2) A sub-surface investigation report by a neighboring
facility [November 1986] shows volatiles contamination
east and southeast of the cap area, an area unaffected
by Stewco past operations.
The volatile contaminants do present a potential risk for health effects to
occur if groundwater is ever utilized at Location 1. However, residents
are currently utilizing the city water system which is upgradient and unaffected
by the site. Barium presents no health hazard as assessed in the risk analysis.
Location 2
Soils Investigation
Organic chemicals were detected infrequently and at low concentrations in
soils at Location 2. Three of the five detected were pesticides; these
concentrations were below averages for cropland soils.
Inorganics in surface soil samples are similar to those levels detected at
Location 1. None of these metals should pose a health risk, as assessed
in the risk analysis. Levels of inorganics in subsurface soils are within
background ranges for this area of Texas.
Surface Water and Sediment
Only one organic was detected in the pond surface water, di-n-butylphthalate
at 3 ug/liter. Although no health criteria exist for this compound,
the low concentration detected does not present a health threat. PAHs were
not detected in the surface water. PAHs in pond sediments which are elevated
from surface soils in the vicinity of the site include naphthalene, 2-methyl
naphthalene, acenaphthene, dibenzofuran, fluorene, anthracene,
benzo(a)anthracene, and benzo(a)pyrene. These concentrations are
still within background concentration ranges for Northeast Texas.
Inorganics in pond surface water which appear at concentrations twice that
of the upgradient groundwater, include barium, iron, and lead. However,
none of these levels are above water quality criteria. Pond sediments.
contain inorganics at levels within background levels of surface soils 'in
the area.
19
-------
Twenty-four organics, other than PAHs, were detected in the pond sediments.
Volatiles of concern in the sediments include benzene, chlorobenzene, and
xylene. None of the volatile* of concern were detected in significant
magnitude in the pond sediments during the 1983 FIT investigation. The
concentrations detected do not pose a significant risk as assessed in the risk
analysis.
Seep sediment samples showed no appreciable organic or inorganic contamination,
Barium, magnesium, and zinc appeared elevated in the swampy area west of
the pond. However, this area was a mud drilling pit for the gas well on
the northwest side of the pond.
Groundwater
Semi volatile compounds detected include di-n-butyl phthalate and
bis(2-ethylhexyl)phthalate and only one PAH, anthracene. Since these
compounds were detected in the pond sediments at Location 2, it can be
assumed that the pond is a potential source of these substances to the
groundwater. However, due to the low concentrations of contaminants
detected, groundwater quality is not significantly affected by the pond.
Health risks were estimated as minimal if the groundwater at Location 2
is ever utilized privately.
The only metals detected in groundwater which are potentially contributed
by the pond include barium and zinc. Barium was detected below its MCL
of 1,000 ug/1. Although health criteria are not available for zinc, no
health effects are anticipated from the levels detected.
Volatile organic compounds found at levels above the detection limit at
Location 2 include benzene and xylene. Although benzene exceeds its MCL
(5 ug/1), the only detection (15 ug/1) occurred in the upgradient shallow
well [GW-4S] west of the pond. Xylene was detected in this same well
and also in the shallow well south of the pond. No health criteria
currently exist for xylene, but health effects are not anticipated for the
low levels of xylene detected. Based on the previous sampling information
(1983 FIT), the distribution of volatiles currently, and the other potential
sources surrounding the site, the pond has been determined to not be
contributing volatile organic compounds to the groundwater.

Site Risk Assessment Summary
The following public health evaluation (PHE) summary highlights the broad
concerns raised as a result of the risk assessment process, but does not
present the numerous assumptions and constraints employed in the PHE.
Please refer to the Remedial Investigation Report to understand the full
context of this brief summary.
The PHE was conducted using conservative assumptions according to the
general risk assessment guidelines outlined by EPA (Superfund Public Health
Evaluation Manual, 1986). The purpose of using conservative assumptions is
to explore the potential for adverse health effects using conditions that
tend to overestimate risk. This assures that the final estimates will usually
be near or higher than the upper end of the range of actual exposures and
risks. As a result, the assessment of risk should not be construed as
presenting an absolute estimate of risk to human populations. Rather, it
is a conservative analysis intended to indicate the potential for adverse
impacts to occur.
Since many chemicals were detected infrequently at both locations, all
chemicals of concern were retained for evaluation in the risk assessment.
As evidenced in Tables 3 and 4, those chemicals of concern for each location
which have Applicable or Relevant and Appropriate Requirements (ARARs) are
not necessarily contributed by the site. Therefore, the potential for site
related contaminants of concern to impact human health and the environment
are evaluated separately and summarized in Tables 5 and 6.
Conservative exposure scenarios were developed which address those "maximum
plausible cases" of exposure that current nearby residents may be subject
to under current and future site use conditions. These "maximum plausible
cases" assume an individual is exposed to the maximum concentration level
detected onsite every time exposure occurs. For example, a trespassing
youth at Location 1 may ingest 1.5 g/day of soil through hand to mouth
interaction each time he visits the site between the ages of 6-16. Over an
expected 70 year lifetime, he may have a two in one million chance of
developing cancer due to the maximum concentration of carcinogenic PAHs
onsite. This maximum concentration was used along with a factor for the
most potent carcinogen onsite, benzo(a)pyrene, even though this compound
represents only a minor portion of the carcinogenic PAHs detected onsite.
Therefore, the estimated risk of two in one million is the extreme upper
bound risk for Location 1. The actual risk is most probably lower and can
even be zero.
The "worst case" scenario considers redevelopment of both locations under
unrestricted future land and groundwater use onsite. Since a resident
living onsite would have increased exposure to surface soils and even subsurface
soils through yard-work, etc., the lifetime cancer risk for Location 1 is
increased from two in one million to eight in ten thousand. However, this
risk is again assuming that the resident is consistently exposed to the
most potent carcinogen at the maximum concentration of PAHs detected onsite.
Assuming that the resident also utilizes the groundwater beneath th£ site,
this risk is not increased in terms of PAHs since no carcinogenic PAH was
detected in the groundwater. Health risks from the detection of bis(2-ethylhexyl)
phthalate, another semi-volatile compound detected in the groundwater, are
significantly lower than this risk, and therefore, do not increase the
chance of developing cancer.
21
-------
In consideration of the volatiles detected at Location 1 which are believed
to be coming from other sources in the vicinity of the site, a person who
comes into contact with groundwater over their expected 70 year lifetime
might have a one in one thousand chance of developing cancer. This assessment
assumes that a person drinks 2 liters/day of water containing the maximum level
concentration detected in groundwater onsite. This estimate also considers
contact while showering since volatile organics can be absorbed through the
skin or inhaled. Therefore, a high risk exists at Location 1 under the
worst case scenario (where groundwater is utilized) that is not attributed
to Stewco.
Although the same assumptions were used for Location 2, the risks are
significantly lower than those at Location 1 since the only volatile detected
was benzene and only at a very low concentration. Even if benzene detected
in pond sediments were to leach out into the groundwater, exposure to
the estimated concentrations might only present a risk of one in one billion.
Therefore, risk from volatiles at Location 2, whether related to original
contaminants or not, is minimal.

STATUTORY DETERMINATION
Development of remedial alternatives was not warranted for either location
on the following basis:
o Residual contaminants associated with the former ponds at Location 1
and the existing pond at Location 2 do not pose a substantial risk to the
public health or environment.
o Applicable or Relevant and Appropriate Requirements (ARARs) may be
chemical, location, or action specific for a Superfund site. However,
none of these exist for the type of contaminants attributed to Stewco
and in consideration of no further remedial action. Risk estimates
were developed and evaluated in determining the adequate protection of
human health and the environment.
o The expenditure of additional funds to implement a remedy at Stewco
would not result in significant additional protection of human health or
the environment. Therefore, the decision to conduct no further action
at Stewco is considered cost-effective.
Since the previous removal action was effective in mitigating the
threats posed by the site to the public health, welfare, and the
environment, further remediation of soils and/or groundwater would not
substantially reduce the toxicity, mobility, or volume of contaminant
residuals. Background concentrations of PAHs remain onsite and site
contaminants are low in mobility as evidenced by the extremely low and
infrequent concentrations detected in the subsurface and groundwater.
Therefore, further remediation of the site is not warranted. The State
and community support this decision. However, the followup Investigation
on the volatiles contamination not attributed to Stewco is of concern to
area residents as well as the State. The Responsiveness Summary discusses
this concern in more detail.
DOCUMENTATION OF SIGNIFICANT CHANGES
No significant changes to this Record of Decision were necessary from
the Proposed Plan published 1n July 1988.
-------
RESPONSIVENESS SUMMARY
STEWCO, INCORPORATED
RECORD OF DECISION
September, 1988
This community relations responsiveness summary is divided into two sections;
The first section provides a brief history of community interest and concern
raised during the remedial planning activities at the Stewco, Inc. Superfund
site. The second section provides a brief summary of the community concerns
raised during the public comment period and EPA responses to the comments.
BACKGROUND OF COMMUNITY INVOLVEMENT AND CONCERNS
On April 11, 1984, during the Immediate Removal Action at the Stewco site,
the EPA conducted interviews of area residents. Those interviewed were
primarily curious, rather than alarmed about the activities at the site.
When the Stewco site was included on the National Priorities List in
October 1984, the TDWR (now known as the Texas Water Commission) scheduled
an initial meeting for the area residents. Approximately 25 residents
attended the meeting that was conducted on May 22, 1985, at the Waskom City
Hall. The primary concern of those in attendance was the need for a follow-
up investigation to determine if the. Immediate Removal eliminated the threat
to public health and the environment.
In December 1987, EPA prepared and mailed an updated fact sheet on the
Stewco site to all interested citizens on the mailing list. The fact sheet
informed the citizens that EPA would be on site to conduct further sampling
and perform a risk assessment in early 1988. After careful review of the
sampling and risk data, EPA would then determine if further action would be
needed at the site.
In March 1988 EPA completed a Remedial Investigation (RI). The results
of the RI indicate that existing site contamination, poses no significant
public health threat at this time.
In July 1988, a fact sheet was prepared on the proposed plan of action at
the site and mailed to all persons on the mailing list. EPA issued a news
release on July 25, 1988, announcing the proposed plan of action.
The public comment period opened on July 25, 1988, and closed on August 23,
1988. On August 4, 1988, at 4:00 p.m. the EPA met with the Mayor of Waskom,
Texas and the Editors of the local newspapers in the Waskom City Council
Chamber to brief the citizens on the study findings. At 7:00 p.m. the EPA
conducted a public meeting at this same location to brief the citizens on
the study findings; 25 people attended the meeting.
-------
SUMMARY OF COMMENTS RECEIVED DURING THE PUBLIC COMMENT PERIOD
AND EPA RESPONSES.
Although no written comments were received during tne Public Comment
Period, several issues were discussed at the Public Meeting held in Waslcom
on August 4, 1988. The following is a summary of the questions posed at
the public meeting and documented in the transcript, accessible through the
Administrative Record.
Issue #1: How does EPA work with the Texas Railroad Commission and other
such agencies?
Response: In terms of solving the various problems encountered at
Superfund sites, EPA must coordinate not only with State
agencies such as the Railroad Commission but also with local
agencies and other Federal laws relevant to a particular
environmental problem. In this manner if one agency has
authority where the others do not, the problem is still
addressed. Also, where jurisdictions overlap, the agencies
work together to ensure that the more stringent requirement
is met.
Issue #2: What is RCRA's role in relation to Superfund?
Response: The Resource Conservation and Recovery Act (RCRA) program deals
with the regulation of active industries which generate and
dispose of hazardous waste. Superfund deals with sites where a
business has disappeared or declared bankruptcy.
Issue 13: In terms of the ongoing contamination in the area surrounding
Stewco from spills and the contamination in the aquifer, who
will help alleviate the problem?
Response: The EPA and the TWC will investigate and pursue possible
off-site sources in the area which appear to be contributing
volatiles to the groundwater through regulations other than
CERCIA. Off-site sources managing hazardous wastes are subject
to investigation under RCRA. EPA has delegated authority
to the Texas Water Commission (TWC) to carry out the hazardous
waste program in the state of Texas. Off-site facilities not
managing hazardous waste would need to be investigated under
the authority of other regulations such as the Texas
Administrative Code (TAG) 335.4. The TWC has also sent
relevant information to the Railroad Commission for their
review of the situation. For Information on the results
of the TWC investigation, the following person may be
contacted:
Dana Elder
Community Relations Co-ordinator
Texas Water Commission
P.O. Box 13087, Capitol Station
Austin, Texas 78711-3087
-------
Issue #4: Is the EPA interested in private well.s, currently used for
cattle water, which have brine contanination?
Response: Brine is not currently regulated by the EPA or the TWC. If the
brine is associated with some type of oil and gas developmental
activity, tne Railroad Commission might be interested in the
problem.
Issue #5: What is the level of benzene in the groundwater at Location 2
and what are the health hazards associated with it?
Response: A level of 15 ppb in the shallow well upgradient of the pond was
the only detection of benzene in the groundwater at Location 2.
Since no users are located downgradient of the pond, no health
threats currently exist. Although benzene Is found in greater
concentrations in the sediments of the pond, health risks are
negligible due to the type of contact involved.
Based on potential future use of the groundwater and several
assumptions typifying the worst plausible case, (the benzene
leaching out into the groundwater from sediments), a person
might have a one in one billion chance of developing a case of
cancer over an estimated 70 year lifetime. This risk is well
below the action level that EPA utilizes for determining the
need for remediation. Therefore, the main concern of benzene in
groundwater remains focused at Location 1 where other programs
will investigate the potential off-site sources upgradient of
the site.
Issue #6: Are the lead levels in soils onsite and in the vicinity of the
the site safe?
Response: Lead concentrations onsite and in the site vicinity are well
below EPA action levels and do not pose health risks as assessed
in the Remedial Investigation.
