1.0 SITE INFORMATION

The CES Griggs Road VCP Site (CES Environmental Services facility) (the “Site”) is a former industrial cleaning, waste recycling, and waste disposal facility located at 4904 Griggs Road, Houston, Harris County, Texas. This document is an attachment to the CES Griggs Road Voluntary Cleanup Program (VCP) application dated April 8, 2015 and provides the information requested by the Texas Commission of Environmental Quality (TCEQ) pursuant to 30 Texas Administrative Code (TAC) 361.604(c).

CES operated between 2002 and August 2010. On August 13, 2010, CES filed for Chapter 11 bankruptcy and operations at the Site appear to have ceased at that time. On October 13, 2010, the bankruptcy case was converted to a Chapter 7 liquidation proceeding.

1.1 Site Location

The Site is comprised of approximately 7.9 acres located in southeast Houston, approximately one mile north of Interstate Loop 610 (Figure 1). The Site consists of three properties: 4904 Griggs Road, 5910 Wayland Street, and 4900 Griggs Road Street (Figure 2). The Site is located in a mixed residential/commercial area with residential properties bordering the eastern and southern boundaries. A charter school is located on the western Site boundary.

The Site contains:

1. an administration building

2. metal warehouses

3. above ground storage tanks (ASTs)

4. Waste containers such as vacuum boxes, frac tanks, tanker trailers, roll-off boxes, drums/totes, and vats.

Attachment 2 to the VCP Application contains the legal description for the Site.

1.2 Site Operational History

1.3.2 Complaints and Inspections

Between 2005 and 2009, the City of Houston responded to odor and emission complaints by nearby residents (TCEQ, 2014a). During this period, four major events occurred at the Site:

October 2, 2008 – tanker trailer fire;

December 6, 2008 – thermal oxidizer explosion;

December 16, 2008 – carbon scrubber control equipment explosion; and

July 7, 2009 – tanker trailer explosion.

In addition, the TCEQ conducted several compliance inspections between 2008 and 2010.

1.3.3 Emergency Response

As discussed in the Justification Assessment for State-Funded Cleanup (TCEQ, 2014a), several incidents occurred at the Site in 2014, which resulted in the release of waste materials. In May 2014, vandals damaged the security fence and emptied several waste containers onto the ground. Subsequently, heavy rainfall resulted in the release of waste to off-site areas. In an effort to prevent



further off-site releases, the Bankruptcy Trustee constructed a berm in the low-lying areas of the Site and attempted to repair leaking containers.

On April 22, 2014, the TCEQ emergency response contractor mobilized to the Site, and secured the Wayland Street gate, placed absorbent berms at the loading bay entrances to the warehouse and washout building, diked the entrances to the tank farm secondary containment, covered open containers, and covered the dumped materials with plastic sheeting.

In late July and early August 2014, vandals removed portions of the security fence and opened a valve on a tanker truck trailer, releasing an unknown quantity of waste. A second off-site release occurred after a heavy rainfall. Response actions were conducted by the City of Houston, the TCEQ’s emergency response contractor, and the United States Environmental Protection Agency (EPA). These response actions included the removal and disposal of the off-site waste, the construction of physical controls to decrease off-site releases, and the repair of the security fence. In August 2014, USEPA and their emergency response contractor, mobilized to initiate the removal and disposal of hazardous wastes and substances contained in approximately 22 ASTs, two roll-off boxes, 12 frac tanks, 11 vacuum boxes, two tanker trailers, 224 totes/drums, and other containers located at the Site.

As of May 8, 2015, EPA had completed the following removal action tasks (Moore, 2015):

1. Vacuum and roll-off boxes: wastes were removed and sent for disposal and original containers were removed from the Site.

2. Frac tanks: wastes were removed from nine of the twelve frac tanks (three were empty), sent for disposal and original containers rented by CES were removed from the Site.

3. ASTs: liquids and sludges were removed from the 20 steel ASTs and the three poly tanks. The secondary containment for the tank farms were cleaned of oily materials; however residual oil remains under the tanks which needs periodic maintenance.

4. Waste water treatment plant (WWTP) tanks: liquids and sludge were removed from 19 of the 20 tanks and accumulated liquids within the secondary containment were removed. One tank containing lime needs disposal of the contents. The secondary containment for the WWTP requires cleaning to remove sludge and the piping needs to be inspected for waste.

5. Totes/Drums/Miscellaneous containers: Wastes have been bulked and either disposed or awaiting disposal. The majority of empty totes, drums, and miscellaneous containers have been cleaned (pressure washed), cut up, disposed or packaged for disposal. The remaining containers were retained for other tasks.

6. Loading and truck cleaning bays: bays were cleared of debris, wastes and sludge. Final cleaning of the bays remains.

7. Storm water management: contaminated sediments and solids were removed as necessary to ensure that accumulated stormwater did not have a sheen. Storm water drains through silt barriers and absorbent boom prior to discharge to the City of Houston storm sewer. Two 4-inch pipes with ball valves were placed in the sedimentation pond to allow drainage in the event the water reaches approximately 2 feet in height.



As of May 11, 2015, TCEQ completed the following removal action tasks (Andrews, 2015):

1. Removed 15,000 gallons of waste water in frac tank 1004.

2. Transported and disposed of 12 vacuum boxes of used oil from the north tank farm tanks.

3. Transported and disposed of 34 drums and six totes of materials removed from the south tank farm tanks.

Tables 1 and 2 summarize the analytical data for the waste at the Site. Waste materials are characteristically hazardous for corrosivity, chromium, lead, benzene, and/or cresols (EPA, 2014c). Waste constituents include benzene, 1,2-dichloroethane, 1- and 2-methylnapthalene, bis(2-ethylhexyl)phthalate, polycyclic aromatic hydrocarbons (PAHs), lead, mercury, and total petroleum hydrocarbons (TPH).

1.4 Preliminary Assessment

The TCEQ completed the Preliminary Assessment (PA) for the Site in January 2015 (TCEQ, 2015b). The PA is included as Attachment 1 to this report. The goals for the Preliminary Assessment were to:

1. Determine the potential threat to public health or the environment posed by the Site;

2. Determine the potential for a release of hazardous constituents into the environment; and

3. Determine the potential for placement of the Site on the National Priorities List.

The PA documents the Site ownership, operations and waste characteristics, previous investigations, waste sources, and migration exposure pathways, including groundwater, surface water, soil, and air pathways.



2.0 NATURE AND EXTENT OF CONTAMINATION AT THE SITE

Four sampling events have occurred at the Site. In addition, one set of soil and groundwater samples was collected as part of a Phase II Environmental Site Assessment (ESA) at the former Holiday Townhomes property located immediately west of the Site (currently used as a recreational area for the adjacent charter school). EPA collected surface soil samples in the residential neighborhood south of the Site after the stormwater release in August 2014. This section discusses the analytical results of on-site and off-site investigations and compares the data to the Texas Risk Reduction Program (TRRP) residential protective concentration levels (PCLs) (TCEQ, 2014b).

2.1 September 1996 Phase I and Phase II ESA

In September 1996, a Phase I and limited Phase II ESA was conducted on the Site when it was owned by Younger Brothers and operated as a truck terminal (WCM, 1996). The report is provided in Attachment 2. Analytes detected in soil samples are summarized in Table 3.

The report documented the presence of an underground storage tank (UST), an inactive tank truck cleaning rack, an active cleaning rack, and a shop building. Two USTs were formerly registered at the Site. The report stated that an inactive Class III landfill was believed present under approximately 0.5-acre of the property. According to a former Younger Brothers employee, the “landfill” was a gully that was filled with brick, glass, scrap metal and other inert materials. The gully was located in the northern portion of the Site. The gully is shown in the 1945 aerial photograph contained in the ESA.

Eleven borings were advanced in various locations throughout the Site, including near the UST, the cleaning racks, a hazardous waste storage trailer, and near the location of the backfilled gully. Soil samples were collected from the borings and one boring (SB-1), near the UST, was converted to a temporary monitoring well. Two grab samples were collected from soil piles along the Wayland Street right of way.

The soil samples collected near the UST (SB-1 and SB-2) were analyzed for TPH and BTEX. Ethylbenzene and total xylene concentrations were less than the TRRP residential PCLs (TCEQ, 2014b). Benzene and toluene were not detected in the soil samples. The maximum TPH concentration of 1,800 milligram/kilogram (mg/kg) potentially exceeded the residential PCLs for the soil leaching to groundwater ingestion (GWSoilIng) pathway and the total soil combined pathway (TotSoilComb). This sample was analyzed by EPA Method 418.1 and the data cannot be directly compared to the TPH PCLs.

The groundwater sample collected from SB-1 was also analyzed for TPH and benzene, toluene, ethylbenzene, and total xylenes (BTEX). TPH and BTEX were not detected in the groundwater sample.

Other soil samples were analyzed for TPH, volatile organic compounds (VOCs), and semivolatile organic compounds (SVOCs). A maximum TPH concentration of 75 mg/kg was reported for a sample collected near a cleaning rack. The remaining TPH concentrations were less than the residential PCLs. Two VOCs, chlorobenzene and cis-1,2-dichloroethene, were detected in two samples at concentrations less than the residential PCLs. One SVOC, di-n-octyl phthalate, was detected in one soil sample at a concentration less than the applicable residential PCL.



In addition to TPH, VOC, and SVOC analyses, four samples were analyzed for Resource Conservation and Recovery (RCRA) metals. Barium, chromium, and lead were detected in the four samples at concentrations less than the Texas-specific soil background concentrations (30 TAC 350.51(m)).

2.2 October 2009 TCEQ Soil Samples

On October 1, 2009, TCEQ collected eight surface soil samples (0 to 6-inches) around the perimeter of the Site (Figure 3). Samples were analyzed for VOCs, SVOCs, and metals (TCEQ, 2009). Table 3 summarizes analytes detected in soil samples and Attachment 3 contains the laboratory report.

Except for methylene chloride, VOCs were not detected in the surface soil samples. Methylene chloride was detected in six of the eight soil samples; however, it was also detected in the associated laboratory blank. PAHs and phthalate esters (common field and laboratory contaminants) was detected in the soil samples. Concentrations were below the TRRP residential PCLs.

Selenium and silver were not detected in the samples and chromium concentrations were below the residential PCLs. Arsenic, lead, and mercury concentrations exceeded the Texas-specific soil background concentrations (30 TAC 350.51(m)). The Texas-specific soil background concentrations are used for these comparisons because the GWSoilIng PCLs are lower than background. One cadmium and two barium concentrations exceeded the GWSoilIng PCLs. Other than arsenic, metals concentrations were below the TotSoilComb PCLs. Except for one location, arsenic concentrations were below the TotSoilComb PCLs for residential exposure. The arsenic concentration of 26.9 mg/kg in soil sample 013063-07 collected from the southwest corner of the property slightly exceeded the TotSoilComb of 24 mg/kg.

2.3 August 2010 Phase II ESA

In July 2010, Enercon Services conducted a Phase II ESA to evaluate property conditions for Bank of America (Enercon, 2010). Thirteen soil borings were advanced to a depth of 20 feet bgs (Figure 3) and samples were collected from the interval of the highest organic vapor meter (OVM) reading and at the terminal depth of each boring. Soil borings indicated the presence of clay to approximately 14 to 20 feet below ground surface (bgs). Sand, if present, was encountered approximately 14 to 20 feet bgs.

Soil samples were analyzed for VOCs, SVOCs, TPH, and RCRA metals. A temporary monitoring well was installed at SB-2; however no groundwater accumulated in the well during the day so a groundwater sample was not collected. Soil data are summarized in Table 3. The Phase II ESA is provided as Attachment 4.

Soil sample concentrations were less than the TotSoilComb PCLs for residential exposure.

TPH was detected in one sample at concentrations less than the residential PCLs. Arsenic concentrations in three samples exceeded the Texas-specific soil background concentration of 5.9 mg/kg (30 TAC 350.51(m)). Lead concentrations in five samples also the exceeded Texas specific soil background concentration of 15 mg/kg. Barium and mercury concentrations in one sample



exceeded the applicable Texas-specific soil background concentrations. Cadmium, chromium, selenium, and silver concentrations were less than the residential GWSoilIng PCLs.

PAHs were detected in three soil boring samples. Concentrations were less than the residential PCLs for the GWSoilIng pathway.

Eight VOCs, acetone, n-butylbenzene, sec-butylbenzene, carbon disulfide, 1,1-dichloroethane, cis-1,2-dichloroethene, methyl-tert butyl ether (MTBE) and methylene chloride, were detected in at least one soil sample. Other than methylene chloride, soil concentrations of the other VOCs were less than the residential PCLs for the GWSoilIng pathway. Methylene chloride concentrations ranged from 0.0034 to 0.0165 mg/kg. However, methylene chloride, a common VOC laboratory contaminant, was detected in the associated laboratory blanks at 0.005 mg/kg and these detections would be qualified as non-detect.

2.4 January 2011 Phase II ESA

In December 2010, TGE Resources, Inc. (TGE) conducted a Phase II ESA at the former Holiday Townhomes property, located immediately west of the facility (TGE, 2011). Three soil borings were advanced to 36 feet bgs and temporary wells were installed in the borings (Figure 3). Two of the borings were installed adjacent to the CES property fence line. One soil sample and one groundwater sample were collected from each soil boring; samples were analyzed for VOCs, TPH, and RCRA metals. Soil and groundwater sample data are summarized in Tables 4 and 5, respectively. The Phase II ESA is provided as Attachment 5.

VOCs and TPH were not detected in the soil and groundwater samples.

Metals concentrations were less than the residential TotSoilComb PCLs. Other than lead, soil metals concentrations were below the higher of the Texas-specific soil background concentration or the GWSoilIng PCLs. Lead concentrations in the three soil samples ranged from 23.7 to 61.2 mg/kg, higher than the Texas-specific soil background concentration of 15 mg/kg.

Other than lead and chromium, groundwater metals concentrations were less than the residential GWGWIng PCLs. The lead concentrations ranged from 0.00083 to 0.025 mg/L and the chromium concentrations ranged from 0.00148 to 0.116 mg/L. The lead and chromium GWGWIng PCLs are 0.015 and 0.1 mg/L, respectively. TGE attributed the lead and chromium exceedances in TSB2 to the naturally occurring suspended sediment in the temporary well.

2.5 January 2014 Site Soil Data

In January 2014, the Bankruptcy Trustee collected four surface soil (0- to 1-feet bgs) samples from the AST tank farms (Figure 3) (IKON, 2014). Samples were analyzed for VOCs, SVOCs, and RCRA metals. Sample detections are summarized on Table 3 and the laboratory report is provided as Attachment 6.

Soil sample concentrations were less than the residential PCLs for the TotSoilComb pathway.

The only SVOC detected in the soil samples was bis(2-ethyl)hexyl phthalate. The only VOCs detected in the soil samples were 1,2,4-trimethylbenzene, acetone, benzene, carbon disulfide,



ethylbenzene, methyl ethyl ketone, and MTBE. Soil concentrations were less than the residential PCLs for the GWSoilIng pathway.

One arsenic, three lead, and three mercury concentrations exceeded the Texas-specific soil background concentrations. Two barium concentrations exceeded the GWSoilIng PCLs. The remaining metals concentrations were below the higher of the Texas-specific soil background concentrations or the residential GWSoilIng PCLs.

2.6 August 2014 Residential Soil Data

In August 2014, after the storm water release from the Site, EPA collected nine surface soil samples from residential yards along Kingsbury Street south of the Site (Figure 3) (EPA, 2014a). Samples were analyzed for herbicides, pesticides, polychlorinated biphenyls (PCBs), SVOCs, target analyte list (TAL) metals, TPH, and VOCs. Data are summarized in Table 4 and the laboratory report is contained in Attachment 7.

Soil sample concentrations were less than the residential PCLs for the TotSoilComb pathway.

Herbicides and PCBs were not detected in the soil samples. The only pesticides detected were alpha- and gamma-chlordane at concentrations less than the residential PCLs for the GWSoilIng pathway.

Of the 21 metals detected in the soil samples, only the arsenic, beryllium, lead, and mercury concentrations exceeded the higher of the Texas-specific soil background concentration or the GWSoilIng PCLs.

One VOC, acetone, was detected in three samples at concentrations ranging from 0.0194 to 0.0711 mg/kg. Seven VOCs, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, carbon disulfide, ethylbenzene, methyl ethyl ketone, toluene, and total xylenes, were detected at location CES-CS-01-51, the soil sample collected in the ditch leading from the Site (Figure 3). Concentrations of these VOCs were all less than the residential PCLs for the GWSoilIng pathway.

Four SVOCs, benzo(b)fluoranthene, bis(2-ethylhexyl) phthalate, fluoranthene, and pyrene, were detected in soil samples with concentrations less than the residential PCLs for the GWSoilIng pathway.

TPH was only detected at location CES-CS-01-51; concentrations were slightly higher than the residential PCLs for the GWSoilIng pathway.



3.0 POTENTIAL FOR HUMAN EXPOSURE TO CONTAMINATION AT THE SITE

This section discusses the potential for on-site and off-site exposures to COCs reported in the soil and groundwater data summarized in Section 2.

3.1 Potential for On-Site Exposure

EPA and TCEQ are performing a waste removal action to stabilize the Site. The goal is to remove waste materials to reduce potential off-site waste migration to the adjacent residences and school as well as on-site exposure to trespassers (EPA, 2014b). The EPA budget for the removal action is $2,000,000 and the TCEQ has agreed to pay up to $500,000 for waste disposal (EPA, 2014b and TCEQ, 2014a). The Site is currently inactive and the only authorized personnel present on the Site are EPA contractors removing waste materials. This work is conducted under a Health and Safety Plan that specifies monitoring requirements and personal protective equipment to minimize exposure. EPA and TCEQ have secured the Site and enlisted the cooperation of the neighbors to reduce trespasser intrusions.

Based on the 2009 to 2014 data described previously, potential exposure to Site workers appears limited. However, no soil or groundwater samples have been collected at the Site since the May and August 2014 vandalism which resulted in the release of wastes onto Site soils. In addition, several deteriorated waste containers were identified at the Site; soil and groundwater samples have not been collected at these locations.

VOC and SVOC concentrations are less than the residential TotSoilComb PCLs. One TPH and one arsenic concentration exceeded their respective TotSoilComb PCLs.

One TPH concentration, 1,800 mg/kg, for a soil sample collected in 1996 from 2- to 4-feet bgs adjacent to an UST, potentially exceeded the residential PCL for the GWSoilIng pathway. However, this concentration from the EPA Method 418.1 analysis cannot be directly compared to the TRRP PCLs.

The arsenic concentration of 26.9 mg/kg in a soil sample collected from the southwest corner of the property in 2009 slightly exceeded the residential TotSoilComb PCL of 24 mg/kg. This concentration is less than the commercial/industrial PCL of 200 mg/kg.

Other than one methylene chloride concentration which would be qualified as non-detect, VOC and SVOC concentrations in soil samples collected from the Site are less than the residential PCLs for the GWSoilIng pathway.

Arsenic, barium, lead, and mercury concentrations exceeded the higher of the Texas-specific soil background concentrations or the residential GWSoilIng PCLs. One cadmium concentration exceeded the residential GWSoilIng PCL.

Only one groundwater sample was collected from the Site. The sample was collected in 1996 and analyzed for BTEX and TPH, which were not detected.

According to the PA (TCEQ, 2015b), drinking water is supplied by the City of Houston so currently there is no exposure to groundwater that may be impacted by the potential for soil leaching from metals.



3.2 Potential for Off-Site Exposure

The limited available off-site soil data described previously do not appear to indicate a significant potential for off-site exposure to COCs resulting from Site activities. Soil samples were collected from the vacant lot (currently used by the school as a recreational area) (TGE, 2011). Residential yards south of the Site (EPA, 2014a) were sampled after the off-site release of stormwater. No analyte concentrations exceeded the residential TotSoilComb PCLs.

The TPH concentration in a soil sample collected from the ditch leading from the Site exceeded the residential GWSoilIng PCL (EPA, 2014a). Arsenic, beryllium, lead, and mercury concentrations exceeded the residential soil leaching to groundwater ingestion (GWSoilIng) PCLs in several off-site samples.

Lead and chromium concentrations in one off-site groundwater sample exceeded the residential GWGWIng PCLs (TGE, 2011). TGE attributed these concentrations to the naturally occurring suspended sediment in the temporary well.

According to the PA, drinking water to the residences and school is supplied by the City of Houston and as such there would be no exposure to groundwater that may be impacted by either the potential for soil leaching from metals or by metals concentrations in groundwater.

1 INTRODUCTION

The Texas Commission on Environmental Quality (TCEQ) was tasked by the United

States Environmental Protection Agency (EPA) Region 6 to conduct a Preliminary

Assessment (PA) at the CES Environmental Services site in Houston, Harris County,

Texas. The specific goals for the PA are:

• Determine the potential threat to public health or the environment posed by the

site;

• Determine the potential for a release of hazardous constituents into the

environment; and

• Determine the potential for placement of the site on the National Priorities List

(Ref. 1).

Completion of the PA was consistent with EPA guidance for performing preliminary

assessments under CERCLA and included reviewing existing site information, collecting

receptor information within the range of site influence, determining regional geology,

ground water, surface water, determining surrounding population characteristics, and

conducting on- and off-site reconnaissance. This document includes a discussion of

background site information (Section 2), a discussion of migration/exposure pathways

and potential receptors (Section 3), and a list of pertinent references (Section 4) (Ref. 1;

Ref. 2; Ref. 3).

2.2 SITE DESCRIPTION

CES Environmental Services (CES) is listed in the EPA Envirofacts database as

providing general freight trucking, nonhazardous waste treatment and disposal,

miscellaneous waste management services, and remediation services (Ref. 14, p. 2). The

CES site consists of three adjacent properties with a total area of 7.9 acres (Ref. 4, pp. 1,

3, 5). The site is located in a mixed commercial and residential area near the intersection

of Griggs Road and Wayland Street in Houston, Harris County, Texas (Figures 1 and 2).

Buildings currently present at the site and formerly used in business operations include

a business office, a training center/locker room, the main processing facility, the tank

wash office, a shed, and a warehouse. The main processing facility is a metal building

that consists of a combined wastewater treatment system located in the north end, and a

former laboratory and drum/container receiving area located in the south end. The

former tank wash office is located in a separate metal building south of the main

processing facility. Wastes are staged throughout the site in a myriad of vessels,

including vacuum boxes, roll-off boxes, frac tanks, tanker trailers, totes, vats, drums,

aboveground storage tanks, and other miscellaneous smaller containers (Ref. 5, pp. 6, 8,


6

10, 12, 14; Ref. 6, pp. 6, 7, 9, 11-28). Ponded storm water has been observed in the

southwest corner and north end of the site in multiple TCEQ site visits (Ref. 6, pp. 3, 8,

15, 21; Ref. 7, pp. 2-4, 6, 7, 9, 10, 12, 17, 22, 25). Operations at the facility ceased in 2010

due to bankruptcy liquidation, and the site is currently inactive (Ref. 8, p. 1; Ref. 9, p. 1).

The properties located immediately east and south of the site are residences (Figure 3).

A few of the residences bordering the northeast corner of the site are currently

abandoned (Ref. 5, p. 16). Griggs Road borders the site to the north, and other

residences are present on the north side of the road. A vacant, open lot is located on the

west side of Wayland Street, north of the on-site warehouse. The Beatrice Mayes

Institute Charter School is located northwest of the on-site warehouse, adjacent to the

vacant lot (Figure 3). The school uses the property located southwest of the on-site

warehouse for physical education activities (Ref. 5, p. 2). This property is not currently

considered part of the CES site; however, according to historical aerial photos, it

appears to have been used for business operations associated with the site beginning at

some point after 1943 and continuing until as recently as 2007 (Ref. 10, pp. 1-6).

2.3 OWNERSHIP HISTORY

Prior to commercial development in the early 1940s, the properties associated with the

site were used as agricultural land (Ref. 49, p. 14). In the early 1940s, the Younger

family used the site for their business to sell horses to the United States Army. Their

business grew into transportation by livestock-drawn flatbed trailers, which later

became a flatbed trucking business (Ref. 49, p. 20). The oldest building still located on-

site, the warehouse on Wayland Street, dates to 1977 (Ref. 10, p. 2). Younger

Transportation owned the 4904 Griggs Road property from 1984 to 1988, and was

merged into Younger Brothers Inc. in 1986. Between 1988 and 1998 the property was

owned by Younger Brothers Inc., which used it for tank truck dispatch, cleaning, fueling,

and storage and maintenance (Ref. 4, p. 7; Ref. 49, p. 5). In 1998 the property was sold

to Suttles Truck Leasing Inc., a freight shipping and trucking company that

accommodated hazardous material and hazardous waste transport needs. Dana


7

Transport Inc. acquired Suttles Truck Leasing Inc., in 2000 (Ref. 4, p. 7; Ref. 12, p. 12;

Ref. 50, p. 1).

CES acquired the property at 4904 Griggs Road on June 11, 2002, and operated as a

domestic for-profit corporation (Ref. 4, p. 7; Ref. 11, p. 1). The properties located at 4904

Griggs Road, 4900 Griggs Road and 5910 Wayland Street are currently owned by CES,

with Matt Bowman as the registered agent (Ref. 4, pp. 1, 3, 5). On August 13, 2010, the

company filed for bankruptcy and David Askanase was appointed as the Bankruptcy

Trustee. He began assessment and disposal of many of the wastes left at the property

(Ref. 8, p. 1; Ref. 29, p. 8).

2.4 OPERATIONS AND WASTE CHARACTERISTICS

Younger Brothers Inc. used tank truck trailers to haul a variety of petrochemicals.

Products stored or used at the property between 1984 and 1998 include sodium

hydroxide, inorganic acid, sulfuric acid, caustic tank cleaner, and diesel fuel (Ref. 4, p. 7;

Ref. 49, p. 5). Truck washing sludge was disposed at the property in an onsite landfill for

disposal of Class III inert waste materials. The landfill is no longer present at the site but

its previous location may have coincided with the portion of the Kuhlman/Belmont

Gully that once flowed through the property (Ref. 49, p. 7, 20).

CES began operating at the site in 2002 as a tank truck cleaning facility and a combined

waste treatment facility. The facility cleaned approximately 3,000 truck trailers, roll-off

boxes, totes, and other types of transportation equipment each year. CES removed and

managed petroleum products, paint thinners, acids, and caustic soda solutions from the

containers (Ref. 29, pp. 3-4). Other services at the facility included used oil recycling,

waste transportation, waste packaging, and waste disposal. The company managed

hazardous industrial wastes and wastewater, and was registered as a solid waste

generator, receiver, transporter, and transfer facility (Ref. 29, p. 4).


8

CES has an industrial waste permit, TCEQ IHW Permit No. 39048, as well as a permit

to pre-treat wastewater, Permit No. TXR05T850 (Ref. 29, p. 4). Wastewater discharged

by the facility was handled by the City of Houston through the Industrial Waste Permit

Nos. 6806 and 9558. Permit No. 6806 was terminated in October 2009 after the

company discharged hazardous waste in violation of this permit into the City of Houston

sanitary sewer system (Ref. 29, p. 4; Ref. 30, p. 1). This discharge reportedly destroyed

the City of Houston’s ability to treat waste at the Sims Bayou wastewater treatment

facility, and caused a release of phenolic compounds into Sims Bayou (Ref. 32, p. 1; Ref.

31, pp 1-2). The company also registered for air permit-by-rule (PBR) 83191 to handle

and recover methylene chloride, as well as PBR 83798 to authorize an oil quality

improvement operation that treated oil to remove water and other impurities (Ref. 34, p.

2; Ref. 33, p. 2).

Other operations at the facility included recycling of methyl ethyl ketone (MEK) wastes.

Mixtures of either methanol, non-volatile polymer solids and water, or MEK and water

entered the facility through tank trucks and were pumped into the recycle distillation

system for processing. Water from the distillation process was sent to the on-site

wastewater treatment facility (Ref. 35, p. 3). On December 6, 2008, an explosion

occurred at the site due to CES’s attempt to combust MEK vapors or liquids in the

thermal oxidizer. The event released 239 pounds of MEK to the atmosphere in 13

minutes, exceeding the rate of 1.8 pounds per hour, calculated as the maximum

authorized rate in 30 Texas Administrative Code §106.262. On July 7, 2009, another

explosion occurred during the opening of a hatch on a tanker truck, and resulted in the

release of 36.87 pounds of methanol and ethanol (Ref. 29, pp. 37-39).

During a site visit in March 2009, TCEQ investigators noted that a 20,000 gallon tank

used by CES to store incoming wastewater had no secondary containment. The

wastewater constituted characteristically hazardous waste due to benzene toxicity. The

investigators also noticed eleven 300-gallon totes, four “first flush” totes in wash bays,

and four 55-gallon drums, all containing hazardous wastes. In addition, two tanker


9

trucks (Nos. 7253 and 221) containing characteristically hazardous waste due to

methanol toxicity were observed (Ref. 29, pp. 36-37).

Between March 2005 and March 2009, the TCEQ documented at least 20

environmental violations that resulted in enforcement actions. These violations included

failure to maintain records, storage of non-permitted hazardous wastewater, operation

of tanks without secondary containment, failure to conduct required tests and

inspections, and failure to label hazardous waste containers (Ref. 13, pp. 1-2). Since

2009 there have been two formal enforcement actions and two informal enforcement

actions associated with the site. During the last facility inspection in April 2010, 15

RCRA violations were documented (Ref. 9, p. 4).

2.5 PREVIOUS INVESTIGATIONS

In May 2009, soil and ground water samples were collected approximately two blocks

east of the CES facility as part of a Limited Phase II Environmental Site Assessment that

was conducted at 4922 Griggs Road (Ref. 36, p. 3, 9). Ground water samples collected at

a depth of 20-30 feet below ground surface from three borings at the property had

concentrations of 1,2-dibromo-3-chloropropane, tetrachloroethene, trichloroethene,

and 1,2-dichloroethane at levels exceeding their respective maximum contaminant

levels (MCLs). Chloroform was also detected in one of these samples at a level

exceeding the SCDM benchmark for cancer risk (Ref. 36, pp. 5, 14-15; Ref. 52, pp. 10, 12,

13, 18, 19). Soil samples collected at a depth of 2-5 feet had concentrations of arsenic at

levels exceeding the SCDM soil pathway benchmark for cancer risk (Ref. 36, pp. 11-13;

Ref. 52, p. 6). The assessment identified CES as a potential source of this contamination

(Ref. 36, p. 6).

Soil samples were collected at the CES site on October 1, 2009, by the TCEQ Industrial

and Hazardous Waste Section. Detected analytes included polycyclic aromatic

hydrocarbons, metals, phthalates, and methylene chloride. Additionally,

benzo(a)anthracene, benzo(a)pyrene, indeno(1,2,3-cd)pyrene, arsenic, and chromium


10

were detected at levels exceeding their respective SCDM soil pathway benchmarks (Ref.

37, pp. 8-55; Ref. 52, pp. 6-8, 11, 14).

In March 2014, vandals dumped the contents of two tanker trailers and seven roll-off

boxes on the ground and into on-site containment structures in order to steal the

equipment (Ref. 38, p. 1). An emergency action was conducted by the TCEQ Houston

Regional Office in response. TCEQ personnel secured the entry gate, placed piles of

contaminated debris on plastic sheeting with plastic covering, and used soil to build

containment dikes around chemical containers and secondary containment structures

(Ref. 39, p. 4).

On August 1, 2014, a release from an open valve on Tanker Trailer 408 occurred (Ref. 7,

pp. 1, 6; Ref. 6, p. 12). Storm water runoff from the site carried the oily water mixture

into the residential neighborhood southwest of the site on Kingsbury Street (Ref. 38, p.

1). The City of Houston and TCEQ Houston Regional Office conducted another

emergency action in response, which consisted of removing the spilled material from

storm sewers, flushing the storm sewers, removing the oily material from ponded areas

on the site, repairing soil containment structures, and placing a containment structure

to prevent offsite drainage from the facility. The EPA repaired the security fencing

around the site, and sampled soil in the drainage ditch, storm water, air, and the

contents of Tanker Trailer 408 (Ref. 39, p. 4; Ref. 7, p. 6). Storm water samples collected

in a vegetated drainage ditch along the surface water pathway located next to Wayland

Street, between Keystone Street and Dewberry Street, indicated detections of acetone,

MEK, metals, pesticides, 1-methylnaphthalene, 2-methylnaphthalene, and phenolic

compounds. Aluminum, lead, nickel, selenium, and alpha-chlordane were detected at

levels exceeding the SCDM surface water pathway environmental benchmark for acute

freshwater exposure (Ref. 42, pp. 1-19; Ref. 47, p. 1; Ref. 52, pp. 5, 9, 15-17).

The EPA began a response action in August 2014 to sample the on-site containers and

dispose of the chemicals which are considered to pose a threat to public health and

welfare. This ongoing removal action will include the clean-up and disposal of all


11

containers and visually contaminated asphalt, concrete, soil and debris. The EPA also

plans to dewater the pooled areas of the site and remove contaminated sediment.

Samples collected in September 2014 from the ponded storm water at the site indicated

detections of acetone, arsenic, manganese, lead and 4-methyl-2-pentanone. Aluminum,

lead and nickel were detected at levels exceeding the SCDM surface water pathway

environmental benchmark for acute freshwater exposure (Ref. 42, pp. 20-61; Ref. 52, pp.

5, 15, 16). Contaminated storm water will be discharged into the City of Houston’s

sanitary sewer to reduce runoff into the storm drains (Ref. 38, p. 2). The Trustee

continues to address waste issues at the site in coordination with the TCEQ and EPA

(Ref. 38, p. 1).

2.6 SITE VISIT

On September 24, 2014, TCEQ Superfund Section staff visited the site and adjacent

residential neighborhoods. The earthen berm constructed by the City of Houston to

prevent storm water runoff from the site to Kingsbury Street was still in place (Ref. 5, p.

4; Ref. 6, pp. 3, 17). There was also an eroding earthen berm present on the northeast

side of the site to prevent surface water runoff into the residential properties on the east

side of the site. During large flood events, storm water may flow over the berm and into

residential backyards located along the eastern fence of the site. TCEQ staff also

observed several egrets and killdeer wading in the ponded surface water on the

southwest and north ends of the site (Ref. 5, p. 12; Ref. 6, p. 21).

TCEQ staff observed evidence of vandalism throughout the site. A former tanker trailer

reportedly cut apart by vandals was located near the former wastewater treatment

system inside the main processing facility. Black oil formerly contained within this

tanker trailer was dumped in the loading bay of the building. During the site visit, an

uncovered vat containing this oil was observed in the main processing facility. TCEQ

staff also observed a trash dumping area in front of the warehouse located on the west

side of Wayland Street (Ref. 5, p. 14; Ref. 6, pp. 23-25).


12

2.7 SOURCES

Potential sources associated with the site include various chemicals contained within

aboveground storage tanks, vats, totes, drums, frac tanks, roll-off boxes, vacuum boxes,

tanker trailers, wastewater treatment tanks, and laboratory sampling containers.

Contaminated soils, asphalt, and concrete are also potential sources (Figure 2).

2.7.1 Source 1: Aboveground Storage Tanks

As of December 2014, 22 aboveground storage tanks (ASTs), each with an estimated

storage capacity between 16,000 and 20,000 gallons, were located at the site (Ref. 38, p.

1; Ref. 45, p. 1). These ASTs are classified into two groups referenced as the North ASTs

and the South ASTs (Figure 2). Both AST groups are surrounded by concrete secondary

containment; however, the concrete containment structure does not entirely surround

the ASTs. In places where concrete walls are missing, earthen berms have been

constructed to prevent releases from the containment structure (Ref. 7, p. 12). At the

time of the TCEQ site visit in September 2014, a black oily sludge material was observed

within the secondary containment of the South ASTs. This material appeared to be

leaking from the earthen portion of the containment wall (Ref. 6, pp. 14, 16).

Samples collected from the ASTs in September 2014 indicated detections of sulfide,

benzene, MEK and phenolic compounds, as well as other volatile organic compounds

(VOCs) and semi-volatile organic compounds (SVOCs) (Ref. 48, pp. 6-42). The contents

of three of these ASTs have been disposed as part of the ongoing EPA removal action

(Ref. 38, p. 1).

2.7.2 Source 2: Vats, Totes and Drums

Four vats containing oily material are located on-site (Ref. 46, p. 20). During the

September 2014 site visit, TCEQ staff observed an uncovered vat inside the main

processing facility that contained black oil previously recovered from the loading bay

located inside the building. Vandals reportedly cut apart a tanker trailer containing this


13

material and dumped the oil in the loading bay (Ref. 5, p. 14; Ref. 6, pp. 23-24). Several

plastic and metal totes and drums were also scattered throughout the facility, many of

them rusted, smashed, corroded, bulging, or in poor condition. Many of these

containers were empty but some contained unidentified materials. TCEQ staff observed

the contents of some of the drums and totes spilling onto the ground, while others had

stained concrete or soil beneath them (Ref. 5, pp. 10, 12, 14, 16; Ref. 6, pp. 12-16, 19-28).

Several of the totes were stacked primarily on the concrete pad south of the South ASTs

(Ref. 5, p. 10; Figure 2).

The inventory conducted by the Bankruptcy Trustee in October 2010 identified

approximately 450 55-gallon drums containing acetone, sump sludge, spent caustic

material, sulfuric acid, spent carbon, residue oil, antifreeze, and ferric chloride.

Approximately 100 totes, each with a 300 gallon capacity, were also identified. They

contained oily water, spent caustic, sludge, sodium hydroxide, non-hazardous paint,

diesel, and ferric chloride (Ref. 45, pp. 1-7).

2.7.3 Source 3: Frac Tanks, Vacuum Boxes and Roll-off Boxes

As of December 2014, there were 12 frac tanks located at the site, each with a 20,000

gallon capacity (Ref. 45, pp. 1-7). One frac tank sampled in 2011 contained hazardous

levels of benzene, o-cresol, cresol, and 2,4,6-trichlorophenol. The other tanks contained

nonhazardous oily water (Ref. 39, pp. 19-22). Samples collected from these tanks in

August 2014 indicated detections of metals, MEK, acetone, naphthalene, benzene,

phenolic compounds, pesticides, herbicides, and several other SVOCs (Ref. 48, pp. 49-

72, 100-133). Three of the frac tanks have been disposed as part of the ongoing EPA

removal action (Ref. 38, p. 1).

On September 24, 2014, TCEQ staff observed evidence of corrosion and extensive red

staining on one of the roll-off boxes caused by an unidentified leaking substance (Ref. 5,

p. 12; Ref. 6, pp. 19-20). Some vacuum boxes on site contained hazardous phenolic

caustic substances with strong odors, while others contained oily water and oily sludge


14

with detections of benzene (Ref. 39 pp. 31-50). All but two of these vacuum boxes have

been removed and disposed (Ref. 38, p. 1). These vacuum boxes were located

approximately five feet east of the fence that borders the western portion of the site

(Figure 2). The Beatrice Mayes Institute Charter School uses the property west of this

fence for physical education activities (Ref. 5, p. 2).

2.7.4 Source 4: Tanker Trailers 407 and 408

Tanker Trailers 407 and 408, each with a 5,000 gallon storage capacity, contained oily

water with solids (Ref. 45, p. 6; Ref. 46, p. 15). Samples collected from these trailers in

August 2014 indicated detections of acetone, MEK, naphthalene, ethylbenzene, toluene,

xylene, phenanthrene, dioxins, and phenolic compounds, as well as other VOCs and

SVOCs (Ref. 48, pp. 233-267). The contents of these tanker trailers have been disposed

as part of the EPA removal action (Ref. 38, p. 1).

2.7.5 Source 5: Wastewater Treatment Tanks

There are currently 19 wastewater treatment tanks at the site, each with an estimated

storage capacity of 10,000 gallons (Ref. 45. p. 4; Ref. 38, p. 1). The liquid waste within

these containers consists of a mixture of oily material, acids, and water (Ref. 46, 22).

Samples collected from these tanks in October 2014 indicated detections of acetone,

benzene, chloroform, methylene chloride, MEK, phenolic compounds, naphthalene,

carbon disulfide, and metals (Ref. 48, pp. 134-216).

2.7.6 Source 6: Laboratory Containers, Chemical Products and Waste Piles

TCEQ staff observed a wide variety of sampling containers, many containing unknown

chemicals, within the former laboratory of the main processing facility during the

September 2014 site visit (Ref. 6, p. 21). The Bankruptcy Trustee consolidated and

disposed of the chemicals within these containers, as well as many of the old chemical


15

products stored in the warehouse on Wayland Street. Debris from stolen roll-off boxes

was also removed and disposed of by the Trustee (Ref. 38, p. 1).

3 MIGRATION/EXPOSURE PATHWAYS

The following sections describe migration/exposure pathways and potential receptors

within the site's range of influence.

3.1 GROUND WATER MIGRATION PATHWAY

The target distance limit (TDL) for the ground water migration pathway is a 4-mile

radius that extends from the sources at the site. Figure 4 depicts the ground water 4-

mile TDL.

3.1.1 Geologic Setting

The geologic formations and hydrostratigraphic units found beneath the site, beginning

at the surface and progressing downward, are shown in Table 3.1.

21

The Pleistocene Series consists of Beaumont Clay, Lissie Formation, Montgomery

Formation, Bentley Formation, and Willis Sand (Table 3-1). The Beaumont Clay is the

youngest formation of the Pleistocene age that crops out extensively in Harris County.

The Beaumont Clay is made up of poorly bedded marly clay that is interbedded with

sand lenses (Ref. 17, p. 16, 17).

The Lissie Formation underlies the Beaumont Formation. The Lissie Formation is

considered equivalent in age to the Montgomery and the Bentley Formations, with the

bottom of the latter being considered the base of the Pleistocene. The Lissie Formation

consists of reddish, orange, and gray fine- to course-grained, cross-bedded sands.

Caliche beds, containing finer-grained cemented sands, are often found at the base of

the Lissie Formation (Ref. 17, pp. 10, 16).

The Willis Sand underlies the Lissie Formation and overlies the Goliad Formation. The

Willis Sand consists of reddish, gravelly sands with subordinate clays that grade into the

Goliad Formation toward the southwest of the Gulf Coast (Ref. 17, pp. 16).

The Pliocene Series consists of the Goliad Formation which overlies the Miocene

Fleming Formation. The upper part of the Goliad Formation consists of sands with

caliche cement. The Goliad Formation also consists of coarse-grained sediments,

including cobbles, clay balls, and wood fragments. The sands in the Goliad Formation

are typically whitish-or pinkish-gray interbedded with grayish clays (Ref. 17, pp. 14, 16).

The average annual precipitation in the city of Houston, Texas is approximately 50

inches (Ref. 19, p. 1).

3.1.2 Aquifer System

The site overlies the Gulf Coast aquifer, which consists of five hydro-stratigraphic units,

from youngest to oldest: the Chicot aquifer, the Evangeline aquifer, the Burkeville

confining system, the Jasper aquifer, and the Catahoula confining system (Table 3-1).


22

The Chicot and Evangeline aquifers flow toward the Gulf of Mexico (Ref. 17, pp. 19-21).

The recharge of aquifers mainly occurs through the outcrop of the Chicot aquifer (about

140,000 acre-feet per year); smaller quantities recharge through the Evangeline (about

49,000 acre-feet per year) and the Jasper aquifers (about 33,000 acre-feet per year);

and negligible quantities recharge through the Burkeville confining system (Ref. 17, p.

36).

The Chicot aquifer includes the Beaumont Clay which extends from the ground surface

through the Willis Sand. Due to the high percentage of sand in the aquifer formations,

the Chicot aquifer is recognized for an abundance of water in Southeast Texas. The

depth of the base of the Chicot aquifer is approximately 700 feet below the ground

surface (bgs) in the site area (Ref. 17, pp. 2, 22-33).

The Evangeline aquifer is approximately 1,300 feet thick and underlies the Chicot

aquifer, spanning the entire thickness of the Pliocene Goliad Formation sands and part

of the Miocene Flemming Formation (Ref. 17, pp. 3-10). The Chicot and Evangeline

aquifers are geologically similar; however differences in hydraulic conductivity form the

basis for distinction (Ref. 20, p. 10). The Evangeline aquifer is considered to be one of

the most prolific aquifers of the Coastal Plain, yielding large quantities of good quality

ground water. In the site area, the Evangeline aquifer extends from approximately 700

feet bgs to approximately 2,000 feet bgs (Ref. 17, pp. 10-15, 22, 33, 38).

The Evangeline aquifer and the underlying Jasper aquifer are separated by the

Burkeville confining system, which consists of 300 feet of silt and clay strata. The Jasper

aquifer is the deepest confined water bearing unit in the Gulf Coast aquifer system in

Texas, and consists of the Fleming Formation and the Oakville Sandstone. The base of

the Jasper aquifer is approximately 3,300 feet bgs in the site area (Ref. 17, pp. 3-11, 15).

The Catahoula confining system underlies the Jasper aquifer and has an average

thickness of 900 feet. The Catahoula Formation is composed of non-marine sands, clays,

and volcano-clastic deposits interbedded with fluvial sediments (Ref. 17, pp. 11-18).


23

During most of the 20th century, the high rate of ground water removal from the Chicot

and Evangeline aquifers in Harris County and surrounding counties caused water levels

to dramatically fall in these aquifers. This problem caused land-surface subsidence

problems and led to the use of surface water as the primary source of potable water in

the area. In the mid-1970s, the City of Houston converted most of its public water

system (PWS) water sources to surface water from Lake Houston, and the San Jacinto

and Trinity rivers (Ref. 17, pp. 33-35).

3.1.3 Drinking Water Receptors

The site is located in a neighborhood supplied by the City of Houston municipal water

supply (MWS). Local lakes and rivers, including the Trinity River, Lake Livingston, San

Jacinto River, Lake Conroe, and Lake Houston, supply the City of Houston surface

water resources. Ground water wells drilled into the Evangeline and Chicot aquifers

with an average depth of 750 feet provide 29 percent of the City’s water supply to

customers predominately located in the west side of Houston (Ref. 15, pp. 2-4). There

are two active Public Water Supply (PWS) wells within four miles of the site; one serves

the City of Houston (PWS #1010013), and the other serves the MD Anderson Cancer

Center (PWS #1013142) (Ref. 16, pp. 1, 3).

There are 75 wells in the Texas Water Development Board (TWDB) Submitted Driller’s

Reports database within the 4-mile TDL, including 4 domestic, 5 irrigation, 5 industrial,

6 geothermal heat loop, 1 rig supply, and 54 test wells. Of these, one irrigation well and

three test wells are located within two miles of the site (Ref. 18, pp. 1-5). The estimated

population for Harris County in 2013 was 4,336,853 (Ref. 21, p. 1).


24

3.2 SURFACE WATER MIGRATION PATHWAY

The surface water migration pathway TDL begins at the probable point of entry (PPE) of

surface water runoff from the site to a surface water body and extends downstream for

15 miles. Figure 5 depicts the surface water 15-mile TDL.

3.2.1 Overland Route

Prior to urban development, surface water drainage from the site flowed directly into

the Kuhlman/Belmont Gully, which once flowed through the northern end of the site

(Ref. 49, p. 16; Ref. 10, p. 1). Currently, a storm water drain on the northwest corner of

the site at Wayland Street and Griggs Road receives surface water runoff from the

northwest part of the property. During the TCEQ site visit on September 24, 2014, all

ponded storm water was being pumped by the EPA to the northwest corner of the site to

discharge into this drain. Earthen berms were constructed in 2014 to prevent storm

water runoff from traveling into residential yards located northeast and southwest of the

site. Before these berms were constructed, storm water from the southwest part of the

site flowed south into a ditch, then west onto Kingsbury Street into a storm water drain

on the corner of Kingsbury and Calhoun Street (Ref. 6, p. 2). Storm water from the

northeast portion of the site likely traveled directly into residential backyards adjacent

to the site, then into a storm water drain located on Grace Lane (Ref. 5, pp. 2, 4, 12; Ref.

44, p. 1).

All storm water drains associated with the site empty into the Kuhlman/Belmont Gully

on the north side of Schroeder Road and Griggs Road (Ref. 44. p. 1). The United States

Geological Survey topographic map indicates that the gully is intermittent; however, the

TCEQ observed standing water in the gully in September 2014 (Figure 1; Ref. 6, p. 1).

This is considered the probable point of entry for the surface water migration pathway.

The Kuhlman/Belmont Gully empties into Brays Bayou, which then empties into Buffalo

Bayou (Figure 5).


25

The 2-year, 24-hour rainfall average for the site area is 5 inches (Ref. 22, p. 3). The site

is not in a Federal Emergency Management Agency (FEMA) designated flood zone (Ref.

23, p. 1).

3.2.2 Drinking Water Receptors

There are no surface water intakes downstream of the site within the 15-mile TDL (Ref.

51, p. 1). The average number of persons per household in Harris County is 2.88 (Ref. 21,

p. 1).

3.2.3 Human Food Chain Receptors

It is likely that local Houston residents occasionally consume fish caught in the

numerous parks along Brays Bayou prior to intersecting Buffalo Bayou, also referred to

as the Houston Ship Channel; however, due to the presence of dioxins, organochlorine

pesticides, and polychlorinated biphenyls, the Texas Department of State Health

Services recommended adults limit consumption of all fish species and blue crabs from

the Houston Ship Channel and its contiguous waters to no more than one, 8-ounce meal

per month. The fish consumption advisory also recommended women of childbearing

age and children under 12 not consume any fish or blue crabs from these waters (Ref. 24,

p. 3). The portions of the TDL within Brays Bayou and Buffalo Bayou shown on Figure 5

are affected by this advisory.

3.2.4 Environmental Receptors

Endangered or threatened species located in Harris County include the following:

Houston toad (Anaxyrus houstonensis), American Peregrine Falcon (Falco peregrinus

anatum), Bald Eagle (Haliaeetus leucocephalus), Peregrine Falcon (Falco peregrinus),

Red-cockaded Woodpecker (Picoides borealis), White-faced Ibis (Plegadis chihi),

White-tailed Hawk (Buteo albicaudatus), Whooping Crane (Grus americana), Wood

Stork (Mycteria americana), Creek chubsucker (Erimyzon oblongus), Smalltooth


26

sawfish (Pristis pectinata), Louisiana black bear (Ursus americanus luteolus),

Rafinesque’s big-eared bat (Corynorhinus rafinesquii), Red wolf (Canis rufus),

Louisiana pigtoe (Pleurobema riddellii), Sandbank pocketbook (Lampsilis satura),

Texas pigtoe (Fusconaia askewi), Alligator snapping turtle (Macrochelys temminckii),

Green sea turtle (Chelonia mydas), Kemp’s Ridley sea turtle (Lepidochelys kempii),

Leatherback sea turtle (Dermochelys coriacea), Loggerhead sea turtle (Caretta caretta),

Smooth green snake (Liochlorophis vernalis), Texas horned lizard (Phrynosoma

cornutum), Timber rattlesnake (Crotalus horridus), and Texas prairie dawn

(Hymenoxys texana) (Ref. 25, pp. 1-6). There are two large HRS-eligible wetlands

within the 15-mile TDL. One wetland segment, located along Brays Bayou, is 77.9 acres

in size and is classified as a riverine lower perennial unconsolidated bottom wetland.

The other wetland segment, located along the Houston Ship Channel, is 2,385.25 acres

in size and is classified as an estuarine and marine deepwater subtidal unconsolidated

bottom wetland (Ref. 26, pp. 1-4). There are no other sensitive environments identified

within the surface water TDL (Figure 5).

3.3 SOIL EXPOSURE PATHWAY

The soil exposure pathway is evaluated based on the threat to resident and nearby

populations from hazardous substances present within two feet of the surface.

3.3.1 Site Setting and Sources

The portion of the site east of Wayland Street is largely covered by impervious concrete

and asphalt throughout the majority of the property (Ref. 6, p. 19). On-site soils are

classified by the United States Department of Agriculture as a mix of urban land and the

Bacliff-Urban land complex with little to no slope. Most soil in the area is either covered

by structures and pavement or disturbed by cutting, filling, or grading. Native soils are

the Bacliff clay in the immediate vicinity of the site and the Vamont clay along the

Kuhlman/Belmont Gully (Ref. 53, pp. 1-3).


27

Extensive staining of the concrete, asphalt and soil at the site was observed by TCEQ

staff in September 2014. The soil formerly underneath Vacuum Box 617 had bright

orange-red and light blue stains. There was black soil staining beneath Vacuum Box 610,

at the former location of Vacuum Box 601 and where the former aluminum shed was

previously located, south of the main processing facility (Ref. 5, pp. 6, 8; Ref. 6, pp. 7-9,

25). Black staining was also observed on the concrete beneath Waste Management Unit

123, near Vacuum Box 406 and beneath an unidentified drum located on the eastern

border of the site. Orange and black soil staining was observed on the property west of

Wayland Street, near the western and southern fence lines, directly adjacent to the

property used by the Beatrice Mayes Institute Charter School (Ref. 6, pp. 11, 19, 21, 26-

27).

In addition to the soil staining, TCEQ staff also noticed oil seeping from the earthen

berm located on the southwest side of the site, which was constructed in response to the

August 2014 release to stop storm water runoff from entering the Kingsbury Street

neighborhood (Ref. 5, p. 10; Ref. 6, p. 18). TCEQ staff observed red staining on the

pavement along Kingsbury Street, likely caused by this release (Ref. 5, p. 4). All on-site

and off-site observed contamination was located within 200 feet of the bordering

residences or school (Figure 2). Soil samples collected from storm water ditches on

Kingsbury Street in August 2014 indicated detections of acetone, carbon disulfide, MEK,

alpha- and gamma-chlordane, metals, and other VOCs and SVOCs. Arsenic was detected

at a concentration of 8.4 mg/kg, which exceeds the SCDM soil pathway cancer risk

benchmark of 0.71 mg/kg (Ref. 47. pp. 1, 16-17, 22-23, 34, 36, 42-47, 56, 64-69, 85-86,

91-92, 103, 105, 114, 116, 125, 132-138; Ref. 52, p. 6).

A 24-hour security guard was present at the site between September 2010 and June

2013 in order to protect the public from hazardous material (Ref. 8, p. 2). Currently,

there is a fence surrounding the entire property to prevent open access to the facility;

however, vandals have previously compromised the security fencing by stealing fence

panels, and the fence has not eliminated vandalism at the facility (Ref. 41, p. 1). Between


28

August and December 2014, two incidents occurred at the site, including theft of

equipment batteries and vandalism of a fence (Ref. 38, p. 2).

3.3.2 Receptors

There are 17 residences located within 200 feet of sources at the site (Figure 3). The

nearest school, the Beatrice Mayes Institute Charter School, is located approximately

200 feet northwest of the site, and includes 443 students (Figure 3; Ref. 27, p. 1). There

are no day care facilities, sensitive terrestrial environments, or land resources within

200 feet of the site (Figure 3).

3.4 AIR MIGRATION PATHWAY

The air migration pathway TDL is a 4-mile radius that extends from sources at the site

(Figure 4).

3.4.1 Air Pathway Receptors

There are 14 residences bordering the site on the east side and three residences

bordering the site on the south side (Figure 3). Sources at the site are within 50 feet of

several of these residences and the nearest home is located 25 feet south of the site

(Figure 2; Ref. 29, p. 3). Since 2005, residents in the area have complained of strong and

offensive odors from the site that resulted in nausea, dizziness, and headaches. From

October 2005 to February 2009, the City of Houston responded to more than 200 odor

and emission complaints from nearby residents, resulting in over 50 notices of violation

and nine citations (Ref. 29, p. 6). From February 2009 to September 2011, there were

270 citizen complaints of nuisance odors, and 65 complaints resulted in notices of

violation. From September 2011 to July 2014, there were an additional 59 complaints of

nuisance odors, one of which resulted in a notice of violation that was issued by the City

of Houston on April 16, 2014 (Ref. 28, pp. 4-6, 11-12, 21-37).


29

The City of Houston Health and Human Services Department analyzed an air sample

collected at the site on January 24, 2008. Contamination detected included methylene

chloride, acetone, benzene, toluene, ethylbenzene, xylene, and other VOCs (Ref. 40, pp.

1-2). Air samples collected at the site by the EPA on August 6, 2014 also indicated

detections of ethylbenzene, benzene, and 1,4-dioxane (Ref. 43, pp. 8-16). During the

September 24, 2014 site visit, TCEQ staff noticed strong phenolic odors and other

unknown chemical odors emanating from various sources at the site (Ref. 5, pp. 8, 12).

The nearest park, Mac Gregor Park, is located 0.4 miles to the north (Figure 4). The

nearest church, Garden of Gethsemane Baptist Church, is located 400 feet northwest of

the site across Griggs Road (Figure 3). According to the 2010 census, 11,853 people live

within one mile of the site (Ref. 9, p. 5).

3.4.2 Environmental Receptors

Mac Gregor Park is the only designated recreation area present within one mile of the

potential sources at the site. There is no commercial agriculture or commercial

silviculture present within 0.5 miles of the site (Figure 4). The largest perennial wetland

near the site is Brays Bayou, which is 77.9 acres in size and is located approximately 0.75

miles north of the site. Other wetlands located within the 4-mile TDL range in size from

0.10 to 2,385.25 acres (Ref. 26, pp. 1-4).
