Pathways, Components, or Threats Not Evaluated

1) Ground Water Pathway: The ground water migration pathway was evaluated but has

not been scored. Private water wells have shown elevated levels of metals (Ref. 5, p. 10). Based on information available at this time, further evaluation of the ground water migration pathway would not significantly affect the listing decision (Ref. 1, Sec. 2.2.3).

2) Surf ace Water Pathway: Ground Water to Surface Water Migration Component: The Surface Water Pathway has been scored for the Human Food Chain Threat and Environmental Threat. The Ground Water to Surface Water Migration pathway has not

been scored . Based on info rmation available at this time, evaluation of this component would not significantly affect the listing decision (Ref. 1, Sec. 2.2.3).

3) Air Migration Pathway: The air migration pathway has not been scored because an observed release to the air migration p athway has not been documented and there are no analytical data to support a release. Based on information available at this time, evaluation of the air migration pathway would not significantly affect the listing decision (Ref. 1, Sec. 2.2.3).

4) Soil Exposure Pathway: The soil exposure pathway has not been scored. Observed contamination has been documented on or within 200 feet of soil pathway targets, but

based on inf ormation available at this time, further evaluation of the soil exposure pathway would not significantly affect the listing decision (Ref. 1, Sec. 2.2.3).

These pathways and components are of concern to the U.S. Environmental Protection Agency (EPA) and may be considered during a future evaluation.1 HRS DOCUMENTATION RECORD

*The street address, coordinates, and contaminant locations presented in this HRS documentation record identify the ge neral area

the site is located. They represent one or more locations EPA considers to be part of the site based on the screening information

EPA used to evaluate the site for NPL listing. EPA lists national priorities among the known "releases or threatened releases" of hazardous substances; thus, the focus is on the release, not p recis ely delineated boundaries. A site is defined as where a hazardous substance has been "deposited, stored, placed, or o therwise come to be located." Generally, HRS scoring and the subsequent listing of a release merely represent the initial determination tha t a certain area may need to be addressed under CERCLA. Accordingly, EPA contemplates that the preliminary description of facility boundaries at the time of scoring will be refined as more information is developed as to where the contamination has come to be located.2 NOTES TO THE READER

Tracking numbers are assigned by the region to every page of every reference. The tracking number consists of the reference number followed by the pag e number within that reference. A tracking number will have a two -digit number followed by the sequential number (for example, 05 001; 05 002).

The following rules were used when citing references in the HRS (Hazard Ranking System) package.

1. The tracking numbers are cited for all references.

2. Hazardous substances are listed by how they appear in the Superfund Chemical Data Matrix (SCDM).

3. Significant figures: Calculations are reported to two significant figures to the right of the decimal place when the HRS does not specify rounding.

Wilcox Oil Company is an inactive and abandoned oil refinery located in Creek County,

Oklahoma. The s ite consists of contaminated areas and surface water bodies due to the release

from the former Lorraine and former Wilcox Refineries . These refineries were located in the N

1⁄2 of the NW 1/4 of S29 T16N R9E and the SW 1/4 of the SW 1⁄4 of S20 T16N R9E in Creek County, Oklahoma (Ref. 5, pp. 4, 5). The location of the releases from the two refineries are considered to be a single site composed of a commingled release from the combined refinery operation s threatening the same targets. The release f rom the two refineri e s is c omingled and /or

the con t amination is conti guous. The Wilcox Oil Company site is composed of a release from the combined facility operations.

The geographical coordinates for the site are 35°50 ’26 .8966 ” north latitude and 96°22’48.693” west longit ude (Ref. 5, p. 4). The property covers approximately 125 acres (Ref. 3; Ref . 5, pp. 4, 5, 23 ; Figure 1 of this HRS Documentation Record ).

Two refinery process facilities and storage tank areas once operated at the two facilities . Recent investigations (2009- 2011) indicate the site area contains elevated concentrations of metals and organic compounds in the former storage tank areas, surface soils , surface impoundment and

sediment s . Elevated levels of metals were also detected in three priv ate residential wells on site, and from three wells adjacent to the property (Ref. 5, pp. 5 – 12, 17-22; Ref. 18 ).

Wilcox Oil Company (Wilcox) operated as a crude oil refin ery from the 1920s until 1963. A skimming and cracking plant was constructed in 1929. The main components of the plant consisted of a skimming plant, cracking unit, and redistillation battery with a vapor recovery system and treatment e quipment (Ref. 12, pp. 3, 5).

The Wilcox Oil Company expanded when it acquired the Lorraine Refinery in 1937, which was located west of the railroad (Figure 1 of this HRS documentation record; Ref. 33, pp. 2, 3). Oil refining began in 1915 at the Lorraine Refinery (Ref. 33, p.2). Wilcox sold the property to a private individual in 1963 (Ref. 13, p. 3). Most of the equipment and storage tanks were auctioned or salvaged for scrap me tal by the new property owners. Wilcox Oil Company no longer o perates in Oklahoma. Based on information from the Oklahoma Secretary of States’ office, the company merged with T enneco Oil Company in 1967 (Ref. 13, p. 15).

A church and six residents are presently on the facility (Ref. 5, p. 13).

A large volume of visible waste is present where refined product and crude oil storage tanks were once located ( Ref. 15, pp. 3, 5, 6 ; Ref. 33, p. 5; Ref. 35). Approximately 4 inches of crude oil were discovered on a church property when a cap broke off an existing pipeline. Hydrocarbon sheen was visible when digging 2-3 feet below ground surface (Ref. 33, p. 4 ). Elevated levels of

metals and semi

- volatiles are present in waste samples collected (Tables 3 and 4 of this HRS documentation record).19 The site includes re m nants of form er oil re fi ning operations and tank farms. The facility can be

divided into three m ajor fo rm er operational area s: two processing areas with surrounding refined product storage and a crude oil storage area. An active railroad divides th e two fo rm er processing areas and product storage areas (Ref. 18 , pp. 1-4). Most of the refinery structures and tanks have been removed or are in ruins. The northwestern portion of the property, west of the

railroad and north of West 221 st Street South/Refinery Road, was used as a refined product storage area but is now rural land no longer used for refinery storage purposes. There are

m

ultiple areas of stressed vegetation, barren areas, and visible black tarry waste of a hydrocarbon nature (Ref. 11, pp. 1-2; Ref. 33, pp. 3, 4, 5 ).

The southwestern portion of the property, south of Refinery Road, west of the railroad had a processing area and refined product storage. The First Assembly of God Church, playground, and one re si dence a r e l o cated whe r e proces si ng and storage o ccur red. The re a r e

m

ultiple a r eas of stressed vegetation, barren areas, and visib le black tarry waste (Ref. 11, pp. 1, 2; Ref. 15, pp. 2, 3).

East of the railroad was a processing area and refined product storage areas. S everal refined product storage tank s, refinery -related debris, dilapidated buildings, and structures remain on the property. There is one re sid e nce in th is portion of the property . An interm ittent str e am (W est
Tributa ry) marks the eastern extent of the processing and refined product storage area east of

the railroad. This trib ut ary ru ns north to south and flows into Sand Creek to the south. Ther e are

m

ultiple are as of stressed vegetation, barren areas, and visible black tarry waste (Ref. 11, pp. 1, 2).

To the ea st of the W est Tributary is a fo rm er large crude o il storage area/tank far m . There are

four residen ces lo cated on top of or dire c tly ne xt to former tank locations. There a r e multi p le areas of stressed vegetation, barren areas, and v i sible black tarry waste of a hydrocarbon nature.

Waste was also obser v ed in several drainage channels that e m pty i nto Sand Creek (Ref. 11, pp. 1, 2).

There are a to tal of six residences on the property, a ll of which are located on form er tank or refinery operations locations. Three of the residences loc ated on the eastern portion of the property are known to use wate r f rom dom estic/ p riv a te wells loc ated on site. The drainage pattern of the property is primarily towards Sand Creek that follows the western and southwestern boundaries of the property. Two interm itte n t strea ms and sever al draina g e ch a nnels cr oss the portion of the property east of the railroad, both of which flow into Sand Creek (Ref. 11, pp. 1, 2).

A detailed title search in the Creek County Cler k office confir ms that the property was used in oil refinery operations from 1915 until Novem ber 1963. Access to the property is not contro lled (Ref. 15, pp. 3, 4). Po r tions of the property are fenced ( Ref. 12, p. 4). There are no schools or day care centers located within 200 feet of the site (Ref. 15, p. 3 )

.

The Wilcox Oil site consists of a former cooling pond, former tank bottoms, and the associated

releases of polynuclear a romatic hydrocarbons ( PAHs ) and metals to the nearby wetlands and20 Sand Creek (Ref. 18, pp. 3, 4; Table 9 of this HRS documentation record).

Leaded tank bottoms are specifically listed as RCRA K052 waste and are CER CLA hazardous substances (Ref. 14, pp.1- 8). In the definition of hazardous substances, Section101(14) of CERCLA provides that “[t]he term does not include petroleum, including crude oil or any fraction thereof which is not otherwise specifically listed or designated as hazardous substance under subparagraph (A) through (F) of this paragraph...”. This provision has been te rmed the “petroleum exclusion”. In the EPA General Counsel’s Opinion Scope of the CERCLA Petroleum Exclusion under Sections 101(14) and 104( a) (2) (July 31, 1987), the EPA interprets the petroleum exclusion to include hazardous substances such as benzene and toluene, which are “indigenous” to petroleum products. The petroleum exclusion also includes “refinery- added” hazardous substances that are normally mixed with or added to crude oil or crude oil fraction during the refining process. Conversely, “contaminants” found in petroleum or petroleum products do not fall within the petroleum exclusion. “Contaminants” include substances which

are no t indigenous to petroleum products or which are present at levels that exceed those normally found in petroleum products (Ref. 14, pp.1-8).

In its decision in US v. Western Processing (1991), the federal district court concluded that “tank bottom sludge is a contaminated waste product, and not a petroleum fraction, as that term is used in [CERCLA].” In so ruling, the court focused in part on the tank bottom’s status as “waste” in contrast to a useful petroleum product, which would be considered a petroleum fraction un der CERCLA (Ref. 36, pp. 1-10). In Cose v. Getty Oil (1993), the U.S. 9 th Circuit of Appeals concluded “crude oil tank bottoms are never ‘subjected to various refining processes’ ; as required by our ‘petroleum’ definition. Moreover, such tank bottoms are not used ‘for producing useful products’...” and “crude oil tank bottoms do not fall within CERCLA’s exclusion of ‘petroleum’, including crude oil or a fraction thereof” (Ref. 37, pp. 1- 9). In addition, the circuit court of appeals also found it u nnecessary to determine whether the level of lead in the refinery sludge exceeded levels indigenous to petroleum products such as leaded gasoline (Ref. 32, pp. 1- 11).

22 SOURCE DESCRIPTION

2.2 SOURCE CHARACTERIZATION

Source characterization for the Wilcox Oil Company site includes identification of the sources, hazardous substances associated with the sources and pathways potentially threaten ed by the

hazardous substances. The re are 1 0 sources evaluated at the Wilcox Oil Company site, for HRS

purposes:

Source No. 1- Cooling Pond

Source Nos. 2-10: Tank Bottoms

The first source evaluated is :

• Source No. 1: Co oling Pond

2.2.1 Source 1 Identification

Number of the source: Source No. 1

Name and description of the source: Co oling Pond (surface impoundment (buried/backfilled)

Source No. 1, a surface impoundment, is located on the east side of the former process and refinery areas at the Lorraine Refinery (Ref. 18, pp. 1-6; Figs. 2 and 3 of this HRS

documentation record ). The area in the vicinity of the surface impoundment contained a cooling

tower , stills and storage tanks (Ref. 18, pp. 1- 6). A church and parking lot near the surface impo undment are now located where the former refinery operations were conducted (Ref. 16, pp. 5, 6 ; Figure 2 of this HRS documentation record ).

The contamination associated with Source No. 1 was based upon analytical results from the ODEQ Site Inspection (SI) (August 2009) (Ref. 16, pp. 6, 12, 13, and 25; Table 5 of this HRS documentation record). Sampling was conducted following the procedures set forth in the Quality Assurance Project Plan (QAPP) (Ref. 39) and the approved DEQ Quality Management Plan (QM P) for State fiscal year 2009 -10, EPA QTRAK # 09-039 ( Ref. 40 ).SO

Source No. 1 is located on the eastern side of the former process and refinery areas of the Lorraine Refinery (Ref. 18, pp. 1-6) (Figs. 2 and 3 of this HRS documentation record ). The sample that was used to define Source No. 1 is LSS -4 ( Table 2 of this HRS documentation

record ).

•Source Type for HRS evaluation purposes: Surface Impoundment (buried/backfilled)

•Containment

Gas release to air: The air migration pathway was not scored; therefore, gas release to

air containment was not evaluated.

Particulate release to air: The air migration pathway was not scored; therefore, particulate containment was not evaluated.

Release to ground water: The ground water migration pathway was not scored; therefore, ground water containment was not evaluated.

Release via overland migration and/or flood: There i s no documentation or evidence to

indicate that Source No. 1 had a maintained run-on control system or runoff management system, or an engineered cover . There is also no evidence of any runoff treatment (Ref. 5, pp. 8, 31-54; Ref. 18, pp. 1-6 ). The contain ment factor value for Source No. 1 is 10 (Ref. 1, Table 4- 2).

2.2.2 Hazardous Substances Associated with a Source

The substances listed in the following pages were present in the sample collected during the 2009 Lorraine Site Inspection from the waste in the former cooling pond (Ref. 16).

The sample contained arsenic, chromium, copper, lead , nickel, and zinc at concentrations equal to or greater than their corresponding reporting limits ( RL s) and waste was evident during sample collection (Ref. 16, p. 17; Table 3 of th is HRS documentation record ). The sample was analyzed for semivolatiles and metals ( Ref. 16, pp. 70, 125 ).SO

2.4.2.1.1 Hazardous Constituent Quantity

The h azardous c onstituent quantity for Source No. 1 could not be adequately determined according to the HRS requirements; that is the total mass of all Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) hazardous substances in the source is not

known and cannot be estimated with reasonable confidence (Ref. 1, Sec. 2.4.2.1.1). There are insufficient historical and current data (manifests, PRP records, state records, permits, waste concentration data, etc.) available to adequately calculate the total mass of all CERCLA

hazardous substances in the source and the assoc iated releases from the source. Therefore, there

is insufficient information to evaluate the associated releases from the source to calculate the hazardous constituent quantity for Source No. 1with reasonable confidence. Scoring proceeds to

the evaluation of Hazardous Waste stream Quantity (Surface Water Pathway) according to the HRS (Ref. 1, Sec. 2.4.2.1.1 and 2.4.2.1.2).

2.4.2.1.2 Hazardous Wastestream Quantity

The hazardous wastestream quantity for Source No. 1 could not be adequately determined according to the HRS requirements; that is the mass of hazardous wastestreams plus the mass of any additional CERCLA pollutants is not known and cannot be estimated with reasonable confidence (Ref. 1, Sec. 2.4.2.1.2). There are insufficient historical and current data (manifests, PRP records, state records, and permits) available to adequately calculate the mass of the

hazardous wastestream or the ma ss of any additional CERCLA hazardous substances in the

source. Therefore, there is insufficient information to evaluate the associated releases from the source to calculate the hazardous wastestream quantity for Source No. 1with reasonable

confidence. S co ring proceeds to an evaluation of volume according to the HRS (Ref. 1, Sec. 2.4.2.1.2 and 2.4.2.1.3).

The sources evaluated at the Wilcox/Lorraine Refinery site, for HRS purposes include:

• Source Nos. 2 - 10 : Tank Bottoms (Pile - other)

2.2.1 Sources 2- 10 Identification

The following information corresponds to sources 2 - 10 identified for this documentation

record

.

Number of the source: Source No. 2 - 10

Name and description of the source: Tank Bottom (Pile -other)

Source No. 2 through Source No. 10 are former tank bottoms located in the central portion of the former process and refinery areas of the Lorraine and Wilcox Refinery . Tank bottoms are generally defined as the liquids and residue, such as heavy hydrocarbons, solids, sands and emulsions, wh ich collect in the bottom of or remain in the bottom of storage tanks after a period

of service (Ref. 4, p. 9 ). Previous investigations identified approximately 6.5 acres of tank bottom material within the storage tank berms in the tank farm area (Ref. 12, p. 6). Tank bottom sediment and oily sludge was also observed in a former remnant of a tank bottom (Ref. 5, pp. 47- 54).

The area of each tank bottom was measured based upon the Sanborn and historical aerial photographs (Ref. 18, Ref. 28). Tank waste bottoms were located in the bermed area for each oil storage tank.

Waste samples were collected during the ODEQ Site Inspection (SI) (August 2009) and Expanded Site Inspection (ESI) of the Lorraine Refinery (September 2010) and the ODEQ ESI

of the Wilcox Refinery (September/December 2011 ) (Ref. 5 , pp. 47-54; Ref. 21;Ref. 22; Ref. 24). During sampling activities, these areas contained oil, tarry and black asphalt- like materials (Ref. 5, p. 5; Ref. 34, pp. 2, 3 ).

•Location of the source, with referen ce to a map of the site:

Source No. 2 through Source No. 10 are located in the c entral portion of the facility. Waste samples were collected from each source. Analytical results are summarized in Table 4 of this HRS documentation record (Figs. 2, 3 and 4 of this HRS documentation record).

2.4.2.1.1 Hazardous Constituent Quantity

The hazardous constituent quantity for Source Nos. 2-10 could not be adequately determined according to the HRS requirements; that is the total mass of all Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) hazardous substances in the sources is not known and cannot be estimated with reasonable confidence (Ref. 1, Sec. 2.4.2.1.1). There are insufficient historical and current data (manifests, PRP records, state records, permits, waste concentration data, etc.) available to adequat ely calculate the total mass of all CERCLA

hazardous substances in the sources and the associated releases from the source s. Therefore,

there is insufficient information to evaluate the associated releases from the source s to calculate the hazardous constituent quantity for Source Nos. 2- 10 with reasonable confidence. Scoring proceeds to the evaluation of Hazardous Wastestream Quantity (Surface Water Pathway) according to the HRS (Ref. 1, Sec. 2.4.2.1.1 and 2.4.2.1.2).

The hazardous wastestream quantity for Source Nos. 2-10 could not be adequately det ermined according to the HRS requirements; that is the mass of hazardous wastestreams plus the mass of any additional CERCLA pollutants is not known and cannot be estimated with reasonable confidence (Ref. 1, Sec. 2.4.2.1.2). There are insufficient historical and current data (manifests, PRP records, state records, and permits) available to adequately calculate the mass of the hazardous wastestream or the mass of any additional CERCLA hazardous substances in the sources. Therefore, there is insufficient inf ormation to evaluate the associated releases from the

33 2.4.2.1.4 Area

Using the historical aerial photographs and the Sanborn maps, by sample collection of waste samples and visual inspection within each bermed area, the diameter of each waste source measured approximately 200 feet (Ref. 18; Ref. 28) . The area source was determined by calculating the area of a circle. (Area of a circle = Π r 2 ).

100 ft. 2 x 3.14 = 31,400 ft. 2

31,400 ft. 2 / 13 = 2,415.38

Each area source for Source Nos. 2-10 will be assigned an area hazardous waste quantity value of 2,415.38.

Other Possible Sources Not Scored

Other possible sources at Wilcox include:

• four tank bottom areas located north and south of Source No. 1 (Ref. 18, p. 4; Figure 5 of this HRS documentation record); two of the tank bottoms are located within the wetland s (Figure 5 of this HRS documentation record ); and

• three tank bottom areas in the former tank farm area (Ref. 18, pp. 2-6).

The possible contaminants associated with the tank bottoms are most probably the same hazardous substances detected in the samples from Source Nos. 2 through 10.SO

The sum of the source hazardous waste quantity values is assigned as the Hazardous Waste Quantity Facto r Value (Ref. 1, Sec. 2.4.2.2). The sum of the source hazardous waste quantity values for Surface Water Pathway is 2 1,796.11 . For a Hazardous Waste Quantity range of greater than >10,000 to 1,000,000 a value of 10,000 is assigned for the migration pathway (Ref. 1, Sec. 2.4.2.2, Table 2

General Considerations:

Four PPEs have been identified. While contamination could have entered the wetlands anywhere along the boundary of the wetlands and the surface impoundment, PPE -1 is the most upstream probable point of entry into the wetlands from the surface impoundment. PPE-1 is located on the western part of the former Lorraine refinery (Figure 5 of this HRS documentation record ). PPE

2 and PPE- 3 are where on

- site intermittent tributaries flow into Sand Creek (Figure 5 of this

HRS documentation record ). PPE

- 4 is located on the eastern side of the Wilcox facility where an

eastern intermittent tributary also flows into Sand Creek (Figure 6 of this HRS documentation

record ). The 15 mile target distance limit is illustrated on Figure 6 of this HRS documentation

record.

Definition of In- Water Segments

The drainage pattern for the site is generally to the south (Ref. 3; Ref. 9, p. 23; Ref. 13, pp. 23, 46; Ref. 30. pp. 1- 2). Th ere are four locatio ns where overland flow of surface waters acr o ss the

s ite e n ters peren n ial waters ( S and Creek) (Ref. 9, p. 23; Ref. 13, pp. 3, 23, 46). Sand Creek meanders approxim ately 3.5 m iles east until it me rges with Li ttle Deep Fork Creek

. Little Deep Fork Creek begins approximately 3.1 miles south east of PPE No. 4 (Figure s 5 and 6 of this HRS documentation record).

Sand Creek

Sand Creek, a perennial stream, is located on the west side of the facility (Ref. 3; Figure 5 of this

HRS documentation record ). Sand Creek flows southward approximately 3.5 miles until it empties into the Little Deep Fork Creek (Ref. 3; Figure 6 of this HRS documentation record).SWOF

- Surface Water Overland Flo w/Flood Migration Component

37 Little Deep Fork Creek

The Little Deep Fork Creek is joined by Sand Creek approximately 3 .1 miles from the farthest

downstream PPE (PPE 4) . The remaining 8.9 miles of the 15- mile target distance limit (TDL) is

contained within the Little Deep Fork Creek , which is a fishery (Ref. 5, pp. 1 -4; Ref. 9, p. 1 ; Ref. 25, p.1 ).

4.1.2.1 Likelihood of Release

4.1.2.1.1 Observed Release

Chemical Analyses:

Field sampling procedures used for the samples collected followed the procedures set forth in the EPA Guidance for Performing Site Inspections under CERCLA , Interim Final, EPA 540-R-92- 021(Ref. 5, pp. 4, 55 ; Ref. 16, pp. 4, 34; Ref. 31, pp. 6, 20 ). The sampling followed the procedures set forth in ODEQ’s Site Assessment Quality Assurance Project Plan ( QAPP) and the approved DEQ Quality Management Plan (QMP) (Ref. 39; Ref. 40). The samples were analyzed for total metals, including mercury, volatile and semivolatile organics using Oklahoma State Environmental Laboratory (SEL) methods and procedures ( Ref. 16, pp. 59-68; Ref. 19).

Release sediment samples were compared to the background sediment samples to support an observed release to the surface water migration pathway. In addition to the chemical analyses, waste was also observed deposited into the stream bank during field activities by ODEQ personnel (Ref. 20, pp. 11, 12).

Soil types on the facility and surrounding are a contain several soil series: t he Stephenville and Darnell fins sandy loams, sloping and gently sloping, the Verdigris silt loam; and Oil

- waste Land. Soils are described by the Creek County Soil Survey as follows (Ref. 16, pp. 7-9 ):

• The Stephenville and Darnell fine sandy loams cover most of the facility. These soils consist of shallow to moderately deep upland soils developed over reddish-yellow to red sandstone or interbedded sandstone and sandy shale (Ref. 16, p. 7).

• The Verdigris silt loam is located in the southwestern portion of the property, along Sand

Creek. These soils occupy the flood plans of streams and are mod erately well drained; however, they are flood occasionally to frequently. Parent material consists of slightly acid to weekly alkaline alluvial sediments washed from soils of the prairies (Ref. 16, p. 8).

• Oil -waste Land has been mapped in areas through the property, occurring in tanks farm and refinery areas. The areas mapped in this soil type have been practically ruined for agricultural use by oil and s alt

- water waste from oil wells. They are more or less gullied and eroded and are almost barren of vegeta tion (Ref. 16, p. 7).

42 Attribution:

The Wilcox facility is an inactive and abandoned oil refinery (Ref. 12, p. 3 ). The facility was active from

1915 until 1960s (Ref. 12, p. 3 ; Ref. 15, p. 4; Ref. 18, pp. 1-4 ).

The hazardous substances used to establish an observed release were associated with the site sources and the site contributed at least in part to the significant increase in the concentration of the hazardous

substances in the observed release. F urth ermore, the haz ardous sub stances were detected at elevated

lev els in intermittent streams o n the property that lead s to Sand Creek (see Tab le 10 of this HRS

documentation record ).

Alternative sites that may be contributing releases of hazardous substances to those found at the Wilcox facility were identifie d. Former refineries were located north of the site. Little information is known

about the dates of operation at these facilities. Sanborn maps from 1915 and 1920 indicate that the property west of the Wilcox Oil facility was occupied by Continental Refining C ompany (Ref. 18). Indiahoma Refining Company was located north of the facility (Ref. 18).

The background sediment samples (SED

- 7, LSD -5, and SED- 9) were collected between any up gradient influences from former refinery activities and the site sources , which indicates that the significant

increase in the concentration of the hazardous substances in the observed release is not due to other sites.

The sources contained the same constituents in the observed release and in the drainage pathway to Sand Creek (see Tables 3, 4, 7 and 10 of this HRS documentation record).SWOF

4.1.3.2.1 Toxicity /Persistence/Bioaccumulation

The human food chain waste characteristics section provides the toxicity, persistence and

bioaccumulation factor values for hazardou s substances that are available to migrate from sources at the site to surface water in the watershed via the overland/flood hazardous substances migration path for the watershed ( Ref. 1, Section 4.1.3.2.1 ), the hazardous waste quantity value for the water shed (Ref. 1, Section 4.1.3.2.2), and the calculation of the human food chain threat- waste characteristics factor category value ( Ref. 1, Section 4.1.3.2.3). The highest combined toxicity, persistence and

bioaccumulation factor is used to determine the was te characteristics factor value for the human food chain threat of the surface water migration pathway ( Ref. 1, Section 4.1.3.2.1.4).

Hazardous substances that meet the criteria for an observed release to surface water and all hazardous substances associated with the sources that have a surface water containment factor value greater than 0 for the watershed are presented in Table 1 1 below. Each hazardous substance eligible to be evaluated is assigned a toxicity/persistenc e/bioaccumulation factor value. The hazardous substance with the highest toxicity/persistence/bioaccumulation factor value for the watershed is used to assign the value to this factor (Ref. 1, Section 4.1.3.2.1.4).

The waste characteristics factor category value is assigned based on the Waste Character istics Product. The Waste Characteristics Product is the product of the Toxicity/Persistence Factor Value and the Hazardous Waste Quantity Factor V alue subject to a maximum of 1 x 10 8 . This product is multiplied by the Bioaccumulation Potential Factor Value subject to a maximum value

of 1 x 10 12 . The hazardous substance with the highest Toxicity/Persistence/Bioaccumulation factor value for the watershed is benzo(a)pyrene ( Ref. 1, Secti on 4.1.3.2.3).

Little Deep Fork Creek, which is located in the 15- mile TDL is a fishery and fish collected are for human consumption (Ref. 25, p. 1). Little Deep Fork Creek is located approximately 3.7

miles downstream of PPE -2, where Sample No. SED- 14 was collected (see Figure s 5 and 6 and

Table 9 of th is HRS Documentation Record).

4.1.3.3.1 Food Chain Individual

A food chain individual factor value of 20 is assigned based on an observed release by chemical analyses of fluo ranthene and p yrene with a Bioac cumulation Factor Value of 500 or greater to sediments within the surface water target distance limit, and due to the fishery present in Little Deep Fork Creek (Sec. 4.1.2.1.1 of this HRS documentation record; Ref.1, Sec. 4.1.3.3.1; Ref. 2, pp. 2, 3, and 10; Ref. 25, p.1; Figure 6 and Table 9 of th is HRS Documentation Record ).

50 4.1.3.3.2 Population

The Population Factor for the watershed is based on three factors: Level I concentrations, Level

II co ncentrations, and potential human food chain contamination.

4.1.3.3.2.1 Level I Concentrations

There are no Level I concentrations established because there were no tissue samples collected (Ref. 1, Sec. 4.1.3.3.2.1).

4.1.3.3.2.2 Level II Concentrations

No Level II concentrations have been established within a fishery.

4.1.3.3.2.3 Potential Human Food Chain Contamination

Fishing is documented in Little Deep Fork Creek. Fish are consumed from Little Deep Creek, but the exact pounds consumed are not kno wn (Ref. 25, p. 1). Although the annual pounds of fish consumed are unknown, since some fish are consumed, the annual pounds consumed are greater than zero. A human food chain population value of 0.03 is assigned for production greater than zero (>0) and l ess than 100 (<100) pounds per year of annual human consumption (Ref. 1, Table 4 -18 ).

According to gauging station #07243500 located in the NW 1⁄4 of the SW 1⁄4 of S20 T14N R12E

in Ok mulgee County, approxim ately 25 m iles southea s t from t he site, the average annual flow rate of the Deep Fork River as measured for water year 1939 through 2011 is 932 cfs (Ref. 29, pp.1- 2). No gauging stations are located on Sand Creek or the Little Deep Fork Creek. The flow rate at the target locations (wetlands, Sand Creek, and Little Deep Fork Creek) was extrapolated using the flow data from Deep Fork River, therefore these segments will be set to equal the flow at the downstream gauging station and will be considered to be a moderate to large stream and will be assigned a dilu tion value of 0.01 (Ref. 1, Table 4-13).

The population factor value is equal to:

A value of 3.0 x 10 -5 is assigned as the Population Factor Value.

4.1.3.3.3 Calculation of Human Food Chain Threat- Targets Factor Category Value

The Human Food Chain Threat - Targets Factor Category value is calculated by summing the food chain individual and population factor values for the watershed:

Food Chain Individual + Population Factor= 20 + 0.00003 = 20.00003

Target Factor Category Value: 20.00003

4.1.3.4 Calculation of Human Food Chain Threat Sco re for a Watershed

The Human Food Chain Threat score is calculated by multiplying the human food chain threat factor category values for likelihood of release, waste characteristics, and targets for the watershed (Ref. 1, Section 4.1.3.4).

Likelihood of Release (550) x Waste Characteristics (1000) x Targets (20.00003) = 11,000,016 (rounded to the nearest integer).

This product is then divided by 82,500:

11,000,016 ÷ 82,500 = 133.33

The resulting value, subject to a maximum of 100, is assigned as the Human Food

Chain Threat Score.

- WASTE CHARACTERISTICS

4.1.4.2.1 Ecosystem Toxicity/Persistence/Bioaccumulation

The environmental threat waste characteristics section provides the ecosystem toxicity, persistence and bioaccumulation factor values for hazardous substances that are available to migrate from sources at the site to surface water in the watershed via the overland/flood hazardous substances migration path for the watershed (Ref. 1, Section 4.1.4.2.1), the hazardous waste quantity value for the watershed ( Ref. 1, Section 4.1.4.2.2), and the calculation of the

environmental threat- waste characteristics factor category value. The highest combined ecosystem toxicity, persistence and bioaccumulation factor is used to determine the waste characteristics factor value for the environmental threat of the surface water migration pathway (Ref. 1, Section 4.1.4.2.3 ).

Hazardous substances that meet the criteria for an observed release to surface water and all

hazardous substances associated with the sources that have a surface water containment factor value greater tha n 0 for the watershed are presented in Table 14 below. Each hazardous substance eligible to be evaluated is assigned an ecosystem toxicity/persistenc e/bioaccumulation

factor value. The hazardous substance with the highest ecosystem toxicity/persistence/bioaccumulation factor value for the watershed is used to assign the value to this factor (Ref. 1, Section 4.1.4.2.1.4).
