Pathways, Components, or Threats Not Scored 

The ground water migration, surface water migration and air migration pathways were not scored in this Hazard 

Ranking System (HRS) documentation record. These pathways are a concern to the EPA and may be considered 

during future evaluations. However, the soil exposure pathway is sufficient to qualify the site for the National 

Priorities List (NPL).
HRS DOCUMENTATION RECORD

Name of Site: 35th Avenue Date Prepared: September 2014

EPA Region: 4 

Street Address of Site*: 3500 35TH N.

City, County, State, Zip Code: Birmingham, Jefferson County, Alabama, 35207

General Location in the State: Central Alabama

Topographic Map: Birmingham North (Reference 3)

Latitude: 33.557464o North

Longitude: 86.799671o West 

The reference point for the above latitude and longitude coordinates is the approximate center of the site area of 

observed contamination (AOC).

Ref: 105, p. 1; see also Figure 2 of this HRS documentation record

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

the general 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 precisely 

delineated boundaries. A site is defined as where a hazardous substance has been "deposited, stored, disposed, or 

placed, or has otherwise come to be located." Generally, HRS scoring and the subsequent listing of a release 

merely represent the initial determination that 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.

SITE SUMMARY 

The 35th Avenue site is located in a mixed industrial and residential area of Birmingham, Jefferson County, 

Alabama, within the area historically known as North Birmingham (Refs. 3; 4, pp. 2, 4, 17-18; 5, pp. 2, 4, 7). The 

site consists of an area of lead, arsenic, and benzo(a)pyrene (BaP)-contaminated soil from multiple possible 

sources, including nearby facility smoke stack emissions and coke oven battery emissions, as well as from 

possible flooding along Five Mile Creek, that have become intermingled over many decades of releases to the 

area (See Figure 1) (Refs. 3; 4, pp. 2, 17-18; 7, pp. 3, 12-14; 106, pp. 12-13, 22; Ref. 110, pp. 1-3; 111, pp. 26-37, 

60-69). The 35th Avenue site and surrounding area include two coke oven plants, asphalt batch plants, pipe 

manufacturing facilities, steel producing facilities, quarries, coal gas holder and purification system facility, and 

the Birmingham-Shuttlesworth International Airport (Refs. 102, p. 14; 103, pp. 1, 159; 104, pp. 1-2). For HRS 

scoring purposes, the 35th Avenue site is the area of observed contamination (AOC) currently documented in the 

soil as a result of the release of hazardous substances from nearby facilities (see Figure 2 of this HRS 

documentation record). However, these releases may extend to areas outside the identified properties in the AOC. 

They may extend to other surrounding areas to the north, south, east and west. Five-mile Creek flows along the 

northern portion of the site; Walter Coke, ABC Coke, U.S. Pipe, and Alabama Gas Corporation (Alagasco) 

facilities are within or near the AOC (see Figures 1 and 2 of this HRS documentation record). The latitude and 

longitude of the site is based on the approximate center of AOC, 33.557464 North Latitude and 86.799671 West 

Longitude (Ref. 105; see also Figure 2 of this HRS documentation record).

The first industrial facilities in this site area of North Birmingham commenced operations in the late 1870s and 

early 1880s. By the turn of the century, the area was home to numerous diversified plants, including foundries and 

kilns, coal and coke by-product plants, a knitting mill, brickworks, and a cement plant (Refs. 5, pp. 2, 4-8; 7, pp. 

12-14). Since 1886, the area has been home to 20 foundries and kilns; seven coal, coke, or byproducts facilities; 

26 scrap and metal processing plants; and four chemical plants (Ref. 7, pp. 12-14). By 1981, 20 percent (%) of 

the land area was devoted to large industrial plants (Ref. 5, p. 8). 

Coke is the residue from the destructive distillation of coal (Refs. 13, pp. 1-3; 14, p. 2; 15, p. 11). When coal is 

subjected to a high degree of heat in the absence of air, the complex organic molecules break down to yield gases, 

together with liquid and solid organic compounds of lower molecular weight, leaving a relatively non-volatile 

carbonaceous matter (coke) (Refs. 13, pp. 1-3; 14, p. 2). Water is used to quench the glowing coke to prevent the 

coke from burning after exposure to air (Ref. 15, pp. 16-17). The volatile products from coal and coal tar 

derivatives are recovered and separated in the by-products plant (Refs. 14, p. 2: 15, p. 17). The coal used in the 

coke plants in the site area was generally obtained from mines in the Birmingham area, until the late 1950s when 

imported ores began supplementing the Red Mountain and Russellville production (Ref. 5, pp. 2-3). Other 

mining areas known to be used are Nebo, Flat Top, Warrior and Blue Creek (Ref. 5, pp. 2-3). Coal from local 

mines continued to be used, and those mines expanded through the 1980s (Ref. 5, p. 3). Coal from mines in the 

Birmingham area and the Black Warrior Basin in west Alabama and the central Appalachians is known to have 

arsenic levels as high as 1,500 milligrams per kilogram (mg/kg) (Refs. 16, p. 4; 17, p. 1; 18). BaP is a known 

contaminant from coke ovens and foundries; arsenic, while also high in local soils, is present at high 

concentrations in the coal from Birmingham and north Alabama, the same coal used in many of the coke furnaces; 

lead is a known contaminant from foundries and other industrial plants (Refs. 5, p. 3; 16, p. 4; 17, p. 1; 18; 19, p. 

1; 106, pp. 12-13, 22; 107, p. 1; 108, p. 1; 109, p. 2). 

Air is the primary source of deposition within the 35th Avenue site AOC, from smokestacks and windblown 

particles from process fines and other stockpiled material; flooding from Five Mile Creek is another source of 

deposition. Aerial deposition of lead, arsenic, and BaP throughout the 35th Avenue site is supported by the 

variability in wind direction as documented in the Wind Rose graphs from 1950-1955, 1970-1975, 1990-1995, 

and 2008-2012 that indicate considerable wind variability in the area (Ref. 100, pp. 1-13). Another source of 

deposition of material includes the sediments of Five Mile Creek, which have been shown to contain lead, arsenic, 

and BaP, and are known to be in a flood prone area (Refs. 110, pp. 1-3; 111, pp. 26-37, 60-69).

Area-Wide Air Monitoring Studies

Since 2005, multiple air monitoring studies have been conducted in the site area in North Birmingham to assess 

the potential health effects resulting from the local population’s exposure to chemicals in ambient air (Ref. 102, p. 

14). The Agency for Toxic substances and Disease Registry (ATSDR) conducted a Public Health Assessment in 

2014 for the area surrounding the 35th Avenue site using the environmental data collected during these studies 

(Ref. 102, pp. 1, 14.) ATSDR concluded that the past and current exposures to air contaminants and particulate 

matter in the communities adjacent to the Walter Coke Incorporated facility resulted in both short- and long-term 

exposures to particulate matter that could have resulted in harmful effects in sensitive individuals (Ref. 102, pp. 

11-12). These studies further document the wide-spread air contamination from local industries in the 35th

Avenue site area. The table below summarizes the findings and the text following the table provides additional 

details.

The Birmingham Air Toxics Study (BATS) 

The BATS was conducted in four locations north of downtown Birmingham by the Jefferson County Health 

Department (JCDH) between July 15, 2005, and June 26, 2006 (Ref. 47, p. 4). The purpose of the study was to 

assess the potential health effects resulting from the local population’s exposure to chemicals in ambient air; a 

subsequent risk assessment was based on the monitoring data (Refs. 47, p. 4). Two locations, Shuttlesworth and 

North Birmingham, were selected by JCHD for proximity to both industrial facilities and adjacent residential 

areas (Ref. 47, p. 6). These two locations are discussed below due to proximity to the 35th Avenue site area. 

The Shuttlesworth air monitoring location was situated between Walter Coke and ABC Coke, due east 

and immediately adjacent to the Walter Coke facility and approximately 1-mile south of the ABC Coke 

facility (Ref. 47, pp. 8, 61). Eleven contaminants considered potential risk drivers for chronic cancer risk 

were identified in air samples collected at this location, including: 1,3-butadiene, acetaldehyde, arsenic, 

benzene, BaP, beryllium, carbon tetrachloride, hexavalent chromium, naphthalene, p-dichlorobenzene, 

and tetrachloroethene (PCE) (Ref. 47, pp. 34). The cumulative chronic (long term exposure) cancer risk 

for these contaminants of potential concern at the Shuttlesworth location was calculated to be 1.66 x 10-4, 

17
Area Letter: A

 

equating to an increased likelihood of 166 additional cases of cancer per one million chronic exposures 

(Ref. 47, p. 34). Additionally, the increased cancer risk exceeds the EPA risk management cleanup 

threshold of 1 x 10-4 increased cancer risk (Ref. 47, p. 31). 

The North Birmingham air monitoring location was situated to the west of the U.S. Pipe facility (Refs. 

47, p. 61). Twelve potential drivers for increased chronic cancer risk were detected at this location: 1,3-

butadiene, acetaldehyde, arsenic, benzene, benzo(a)anthracene, BaP, cadmium, carbon tetrachloride, 

dibenz(a,h)anthracene, naphthalene, p-dichlorobenzene, and PCE (Ref. 47, pp. 33-34). The cumulative 

increased chronic cancer risk for contaminants of potential concern at the North Birmingham location was 

calculated to be 9.92 x 10-5, equating to an increased likelihood of 99 additional cases of cancer per one 

million chronic exposures (Ref. 47, pp. 33-34). 

EPA Schools Monitoring Initiative 

The Schools Monitoring Initiative was conducted by EPA from August 5, 2009 to December 3, 2009 by the 

placement of air monitoring stations at three Birmingham-area schools: Lewis Elementary School at 2015 

26th Ave N, Riggins School at 3177 44th Avenue North, and North Birmingham Elementary School at 2620 

35th Avenue North, as well as from August 5, 2009 through November 24, 2009 at the North Tarrant 

Elementary School at 1269 Portland Street, as part of a nation-wide air toxics study (Ref. 48, pp. i, 1, 5, 9-10, 

64, 65). The studies found levels of coke-related emissions, particularly benzene, arsenic, and BaP, in air 

samples at levels that pose concern for long-term exposure in the schools (Ref. 48, pp. 7-8, 9-17, 22-23, 66-

73). 

Sampling Activities

As part of its RCRA permit, sampling was conducted in conjunction with an Environmental Indicator study at 

residential and school properties in the 35th Avenue site area by Walter Coke in 2005 (Refs. 50, p. F-38; 51, p. 1). 

EPA RCRA requested additional sampling of residential properties in 2009; 75 composite surface soil samples 

within the area and surrounding area of the 35th Avenue site were collected (Refs. 46, p. 2; 51, p. 2; 52, pp. 5-6, 

9). The sampling results indicated that 22 properties in Collegeville, four properties in Harriman Park, and 2 

properties in Fairmont exceeded the cleanup levels for arsenic and/or BaP Toxic Equivalent (TEQ) (Ref. 52, pp. 

17-21). Fourteen areas were resampled in 2010, three sampling locations exceeded the cleanup levels for BaP 

TEQs (Ref. 53, pp. 10-14). In 2011, Walter Coke removed 52,000 cubic feet of soil to a depth of 2 feet due to the 

presence of BaP toxic equivalents at concentrations exceeding the EPA cleanup level at the Hudson School and 

replaced it with clean backfill (Ref. 53, pp. 1-3). As of June 2012, Walter Coke was able to gain access and 

conduct removal activities of 16 of the 23 properties that were identified as having polycyclic aromatic 

hydrocarbons (PAHs) and arsenic concentrations above Removal Management Levels (RMLs) through 

negotiations with EPA RCRA (Refs. 46, pp. 3-4; 56, p. 1-1). 

In March 2011, EPA RCRA submitted the residential sampling data to the EPA Region 4 Emergency Response 

and Removal Branch (ERRB) (Ref. 55, p. 3). The EPA ERRB requested the EPA Region 4 Technical Services 

Section (TSS) to evaluate the 2009 residential sampling results collected by Walter Coke against Removal Action 

Levels (RALs) (Ref. 55, p. 3). The EPA TSS summarized that 16 residential properties, two schools, a former 

school, and a right of way exceeded the RAL of 1.5 mg/kg for BaP TEQ in residential surface soil (Ref. 55, p. 3). 

Therefore, EPA ERRB concluded that the properties meet the criteria for a time-critical removal action (Ref. 55, 

p. 3). Following suspension of negotiations with Walter Coke for sampling of additional properties, EPA ERRB 

began coordinating sampling 1,283 properties as part of the 35th Avenue Removal Investigation (Refs. 57, p. 2). 

18
Area Letter: A

The 35th Avenue Removal Investigation was initiated in November 2012 by EPA and was completed on June 25, 

2014 (Refs. 6, pp. 1-2, 7). Sampling was conducted in non-industrial areas of the Harriman Park, Collegeville, 

and Fairmont neighborhoods, which includes the 35th Avenue site (Refs. 4, p. 5; 6, p. 8, App. A, pp. 1-8). The 

Removal Investigation consisted of the collection of composite and grab surface soil samples from residential 

yards and garden areas, playgrounds, schools, churches, apartment housing, and empty lots (Ref. 6, p. 8, App. B, 

pp. 1-88). Vegetation samples were collected as well (Ref. 6, p. 7, Att. 3, pp. 1-53). The Removal Investigation

included the collection of 4,767 surface soil samples for x-ray fluorescence (XRF) screenings, of which 

approximately 14% (677 samples) were also analyzed by a laboratory (Refs. 6, pp. 13-14). The Removal 

Investigation identified 394 properties above the RML for one or more compounds analyzed including lead (400 

mg/kg), BaP (1,500 μg/kg), and arsenic (39 mg/kg) (Refs. 4, p. 20-22; 6, pp. 17-19). The Removal Investigation

identified elevated concentrations of lead, arsenic, and BaP in the residential neighborhoods near the site area 

(Refs. 6, pp. 17-19). The composite surface soil samples collected and analyzed by a laboratory are used to 

determine the AOC scored in Section 5.0 of this HRS documentation record. 

In 2012, EPA conducted two sampling events along Five Mile Creek to support the Removal Investigation at Five 

Mile Creek (Ref. 111, p. 7). The purpose of the investigation was to collect information to determine whether 

contaminants associated with former and current coke and chemical manufacturing operations at nearby facilities 

had impacted Five Mile Creek at levels hazardous to human health and/or the environment (Ref. 111, p. 7). A 

total of 31 in situ screening locations and 27 ex situ sediment samples were screened for metals using an XRF. A 

total of 54 samples, including 36 sediment samples, four surface water samples, four surface soil, seven field 

duplicates, and three Quality Assurance (QA) samples, were collected and submitted for analysis. Analytical 

results confirmed that heavy metals and semi-volatile organic compounds (SVOCs), specifically polyaromatic 

hydrocarbon (PAH) compounds, exist in concentrations above the residential and/or industrial Removal 

Management Levels (RMLs) within the sediment and overburden soil sampling area (Ref. 111, p. 23).

In 2014, the EPA Region IV began the Phase I removal action targeting properties in which the arsenic, lead, 

and/or BaP exceeded the Region IV Removal Management Levels (RMLs) by ten times or exceeding 1,200 

mg/kg for lead. Fifty-eight parcels were scheduled for removal through August 28, 2014, with an additional 30 

properties undergoing removal activities during Phase II activities beginning in September 2014 (Ref. 112, pp. 1-

4). These properties undergoing removal activities, or scheduled to undergo such activities, are not included in 

the calculations for the 35th Avenue site AOC or target populations. 

The driving factor for the HRS site score are residential targets associated with properties subject to BaP and/or 

arsenic and/or lead contamination. According to the HRS, Section 5.1.3, residential targets include a person 

living or attending school or day care on a property with an area of observed contamination and whose residence, 

school, or day care center, respectively, is on or within 200 feet of the area of observed contamination (Ref. 1, 

Section 5.1.3).

Area Letter: A

5.0 SOIL EXPOSURE PATHWAY

5.0.1 GENERAL CONSIDERATIONS

The soil exposure pathway is based on an area of observed contamination (AOC) (Ref. 1, Sect 5.0.1). The AOC 

at the site is based on analytical evidence of hazardous substances present in concentrations three times or greater 

than the designated background levels, if detected in background, and in concentrations greater than the 

corresponding sample quantitation limits (SQLs) (all surface soil samples were collected at a depth of 2 feet or 

less). The AOC is currently defined based on analytical results for soil samples collected in the area during the 

35th Avenue Removal Investigation (Ref. 6). The AOC excludes those properties that have been determined to be 

not contaminated or have had a removal conducted (Ref. 112). See Figure 2 of this HRS Documentation Record.

BACKGROUND LEVEL

Due to extensive industrialization in the North Birmingham area, potential background locations near the site area 

were likely influenced by other industries, or were affected by other coke or foundry facilities. Since 1886, the 

area has been home to 20 foundries and kilns; seven coal, coke, or byproducts facilities; 26 scrap and metal 

processing plants; and four chemical plants (Ref. 7, pp. 12-14). In order establish background conditions for the 

site area the EPA Region 4 Science and Ecosystem Support Division (SESD) and RCRA Division conducted a 

sampling investigation in 2010 in the Robinwood neighborhood. This area was selected because the soil types 

within the neighborhood were determined to have similar composition to those within the 35th Avenue site area,

and the neighborhood is outside the influence of coke production (Ref. 16, pp. i, 4-6). Differences in contaminant 

levels are due to the mode and duration of contaminant deposition (contamination has been aerially deposited on 

the AOC for more than 100 years) (Refs. 3; 16, pp. 5). Additional similarities between the Robinwood 

neighborhood and the 35th Avenue AOC include: home construction and age; the use and storage of coal for home 

heating; residential burn barrels in the neighborhood; asphalt shingles on the home; asphalt roads and the nearby 

rail road line (i.e., non site related factors that could contribute to ambient contaminant levels) (Ref. 16, p. 5). 

Further, the surficial geology of the Robinwood neighborhood is similar to that of the 35th Avenue site (Ref. 16, p. 

5). 

Twenty sample locations were identified during the background sampling investigation conducted by SESD and 

RCRA; see Figures 1 and 2 on pages 30 and 31 of Reference 16 for sampling locations (Ref. 16, p. 7). However, 

only 5-aliquot composite background surface soil samples collected from residential properties were used for 

comparison for the purposes of this HRS documentation record, as only 5-aliquot residential samples were used 

for AOC samples. Only background residential samples were used for comparison as only residential samples 

were used to document the release and define the AOC. From this subset of background samples collected, the 

highest sieved and non-sieved sample was used for comparison to sieved and non-sieved samples collected from 

the 35th Avenue site, respectively. Background and release samples that were collected from a similar depth, 

using the same sampling protocol, and analyzed using the same analytical method are used do document the 

observed release of contamination in the site area for this HRS documentation record (Refs. 4, pp. 4-5, 8-9; 16, 

pp. 6, 28-29). All samples were conducted in accordance with EPA SESD Field Branches Management and 

Quality System Procedure and using the SESD field measurement and sampling operating procedures (Ref. 16, p. 

28). All samples were analyzed according to EPA Analytical Support Branch Laboratory Operations and Quality 

Assurance Manual, January 2010 (Ref. 16, p. 29). The samples were analyzed according to EPA method 8270D, 

200.8, and 6010 (Ref. 16, p. 29).

Contaminated Samples

Contaminated samples obtained from residential yards during the 2013 EPA Removal Investigation sampling 

events are used to document the AOC. The samples were collected from depths of 0 to 4 inches bgs (Refs. 4, p. 9; 

6, pp. 12-14; 62, p. 6). Release samples were compared to the highest value background sample, with the same 

number of aliquots for each composite sample, from a similar depth, from the same type of property, using the 

same sampling protocol, and analyzed using the same analytical methods (Refs. 4, pp. 4-5, 8-9; 6, pp. 12-14; 16, 

pp. 6, 28-29; 63). Sieved and non-sieved background samples were compared to sieved and non-sieved 

contaminated samples, respectively. All samples were collected within 200 feet of the residential home and 

within the legal property boundaries (See the contaminated samples table below and Reference 63 for 

documentation). (See Figure 2 of the HRS documentation record.) Those properties in which removal activities 

were conducted, or are planned to be conducted, are not included in the following list to ensure scoring under 

current conditions (See Reference 112 for the list of properties that have had or are scheduled to have a removal 

conducted). 

All activities and procedures conducted by START during the Removal Investigation were performed in 

accordance with the EPA Region 4 Field Branches Quality System and Technical Procedures (FBQSTP) and the 

site-specific QAPP/SSP approved on October 18, 2012 (Ref. 6, p. 8). All soil samples collected were submitted 

to a NELAC Institute certified laboratory, either Spectrum Laboratory of Tampa, Florida, or TestAmerica 

Laboratories, Inc., of Savannah, Georgia, and Tampa, Florida, for sample analysis (Ref. 6, pp. 14-15). See

The Reporting Limit (RL) listed below is equivalent to the Method Reporting Limit (MRL), adjusted for samplespecific conditions. The MRL is synonymous with a contract required quantitation limit (CRQL). For metals 

analyses where a single point calibration is performed (i.e., a high standard and a blank), the MRL is equivalent to 

the concentration of the reporting limit check standard (Ref. 113, p. 1).

Some of the current and historical coal/coke and foundry-related facilities in the immediate area of the 35th

Avenue site include the active Walter Coke facility located at 3500 35th Avenue; the former U.S. Pipe facility 

located at 3000 30th Avenue North; the ABC Coke facility located at 900 Railroad Avenue in Tarrant City, 

Jefferson County, Alabama (also listed as 1 Railroad Avenue and 900 Huntsville Avenue); and the Alagasco 

facility at 2333 F L Shuttlesworth Drive (also listed as 2337 Huntsville Road) in Birmingham, Alabama (See 

Figures 1 and 2 of this HRS documentation record) (Refs. 8, p. 1; 9, p. 3; 10, p. 1; 11, p. 1; 12, p. 1; 103, p. 1, 

159; 104, pp. 1-3). Particulate and volatile organic compound emissions originate from many operations at coke 

facilities such as Walter Coke and ABC Coke (Ref. 15, p. 20). Organic compounds soluble in benzene are major 

constituents of the particulate material emissions and are also included as VOCs (Ref. 15, p. 20). Substantial 

emissions are also obtained from ancillary operations such as boilers, wastewater treatment, cooling towers, and 

roads (Ref. 15, p. 20). Foundries such as U.S. Pipe can contribute to the deposition of contamination in the area 

by air emissions of metals, such as lead, and polycyclic aromatic hydrocarbons (PAHs), such as BaP, both 

through gaseous emissions and PAHs adsorbed onto dust (Refs. 106, pp. 12-13, 22; 108, p. 1; 109, p. 2). 

Alagasco, a coal gas holder and gas purification facility, could contribute to the deposition of metals via air 

emissions and BaP adsorbed onto dust (Ref. 114, p. 247)

The results of sampling events conducted in the 35th Avenue study area in 2012 and 2013 revealed elevated 

concentrations of lead, arsenic, and BaP at concentrations greater than or equal to background concentrations 

collected from similar residential areas. As explained below, the EPA has determined that there is insufficient 

data to identify the contribution from any individual industry in the area to the soil contamination present in the 

commingled AOC. Therefore, a commingled AOC has been identified at this site. This area includes the releases 

from the industries that operated in and around the 35th Avenue study area as possible origins of the lead, arsenic, 

and BaP contamination. The presence of lead, arsenic, and BaP within the AOC is most likely due to emissions 

from facility stacks, use of solid waste as fill material, and the likely inundation of properties during flood events

(Refs. 15, p. 20; 16, p. 9; 106, pp. 12-13, 22; 108, p. 1; 109, p. 2; 110, pp. 1-3; 111, pp. 26-37, 60-69; 114, p. 247). 

BaP is a known contaminant from coke ovens, foundries and manufactured gas sites; arsenic, while also high in 

local soils, is present at high concentrations in the coal from Birmingham and north Alabama, the same coal used 

in many of the coke furnaces; lead is a known contaminant from foundries and other industrial plants (Refs. 5, p. 

3; 16, p. 4; 17; 19, p. 1; 106, pp. 12-13; 108, p. 1; 109, pp. 2, 18; 114, p. 247). 

North Birmingham was developed in the late 1800s as a planned residential and industrial community (Ref. 5, pp. 

2, 4-6). The first industrial facilities in North Birmingham commenced operations in the late 1870s and early 

1880s (Ref. 5, pp. 2, 4-7; 7, p. 12). By 1920, the area was home to numerous diversified plants, including 

pipeworks, foundries, a knitting mill, brickworks, and a cement plant (Ref. 5, pp. 2, 4-7; 7, p. 12). Since 1886, the 

area has been home to 20 foundries and kilns; seven coal, coke, or byproducts facilities; 26 scrap and metal 

processing plants; and four chemical plants (Ref. 7, pp. 12-14;). By 1981, 20% of the land area was devoted to 

large industrial plants (Ref. 5, p. 8). An industrial survey prepared by Walter Coke identified 76 distinct facilities 

in seven industries that Walter Coke claimed were associated with both metals and PAHs (Ref. 7, pp. 12-14). 

Most of the facilities provided in the survey are outside of the site area (Ref. 7, pp. 12-14; See Figures 1 and 2).

Many of the residences in the area were developed as company housing for the numerous large industries in the 

area (Ref. 5, pp. 4-7). By 1908, the neighborhood of Collegeville was developing east of the current U.S. Pipe

facility (Ref. 5, p. 7). 

Coke is the residue from the destructive distillation of coal (Refs. 14, p. 2; 15, p. 11). Prepared coal is heated in an 

oxygen-free atmosphere (coked) until most volatile components in the coal are removed; the remaining is a 

carbon mass called coke (Ref. 15, p. 11). When coal is subjected to a high degree of heat in the absence of air, the 

complex organic molecules break down to yield gases, together with liquid and solid organic compounds of lower 

molecular weight, leaving a relatively non-volatile carbonaceous matter (Ref. 14, p. 2). Metallurgical coke is used 

in iron and steel industry processes to reduce iron ore to iron (blast furnaces); foundry coke is used by foundries 

in furnaces for melting metal and the preparation of molds (Ref. 15, p. 11). Foundry coke production uses a 

different blend of coking coals, longer coking times, and lower coking temperatures relative to those used for 

metallurgical coke (Ref. 15, p. 11). Most coke plants are co-located with iron and steel production facilities (Ref. 

15, p. 11). 

Most coke is produced in the US using the “byproduct” process, including coke produced at Walter Coke and

ABC Coke (Refs. 5, p. 3; 14, p. 2; 15, pp. 11-14; 33, p. 4). The general process of coking using the by-product 

process is described in Reference 15, pages 15 through 18, and includes coal being charged to ovens; the thermal 

distillation of coal in groups of ovens (batteries) producing coke; the glowing coke being quenched with water, 

and the quenched coke allowed to drain and cool; the coke is then crushed, screened and stored (Ref. 15, pp. 15-

17). The volatile products from coal and coal tar derivatives are recovered and separated in the by-products plant 

(Ref. 14, p. 2). 

Emissions originate from many operations at the coke and byproducts plant (Ref. 15, p. 20). Particulate emissions 

(PM) are emitted from leaks from doors, lids, and offtakes during coking; soaking; pushing coke from the oven; 

hot coke quenching; combustion stacks; and coke crushing, sizing, screening, handling, and storage (Ref. 15, p. 

20). Volatile organic compounds are emitted from coke oven leaks, coke pushing, and coke quenching (Ref. 15, 

p. 20). Organic compounds soluble in benzene are major constituents of the PM emissions and are also included 

as VOCs (Ref. 15, p. 20). Substantial emissions are also obtained from ancillary operations such as boilers, 

wastewater treatment, cooling towers, and roads (Ref. 15, p. 20). Controls for coke plants consist of operation 

and maintenance practices to reduce oven emissions, and application of control devices to specific operations in 

the coke-making and byproduct recovery process (Ref. 15, p. 20). Operation and maintenance practices include 

steam aspiration and staged charging to reduce charging leaks, and sealing of doors, lids and off takes at joints 

that may leak (Ref. 15, p. 20). Sheds ducted to a baghouse and hooded quench cars are available controls for 

pushing and coke-side door leaks (Ref. 15, p. 20, 21). Quenching emissions are controlled by baffles in the 

quench tower to impeded PM flow and the use of non-process water for quenching (Ref. 15, p. 21). Several 

factors can affect emissions from the combustion stack during coke manufacturing, including incomplete 

combustion in the flues or cracks in the brickwork between an oven chamber and flue (Refs. 15, pp. 12, 26; 34 p. 

58). Incomplete combustion is typically the result of excess gas and/or insufficient air in the system (Ref. 34, p. 

58). Excess emissions from damaged brickwork or overly decarbonized ovens are most notable just after an oven 

is charged because gases from combusted coal dust are forced through cracks during charging (Ref. 34, p. 58).

Coal from mines in the Birmingham area and the Black Warrior Basin in west Alabama and the central 

Appalachians is known to have arsenic levels as high as 1,500 mg/kg (Refs. 5, p. 3; 16, p. 4; 17, p. 1; 18). Coal 

from these mines was used extensively in coke plants in the North Birmingham area (Ref. 5, p. 3). The use of this 

coal in many of the coke furnaces in the area concentrates the levels of arsenic during the burning process (Refs. 

19, p. 1; 16, p. 4; 5, p. 3; 17, p. 1; 18)

The following facilities have been identified as possible or likely contributors to the lead, arsenic, and/or BaP 

contamination found in the AOC due to their proximity to the AOC, the type of plant, the processes utilized at the 

plant, and the history of releases contributing to the commingled contamination of the AOC over the period of 

many years. A brief history of the facility, their processes, permits and violations, as available, is provided below. 

Walter Coke 

Walter Coke, also known as Sloss-Sheffield Steel and Iron Company; United States Pipe and Foundry Company; 

Jim Walter Resources, Inc.; and Sloss Industries, has operated as a coke plant at the 35th Avenue facility since 

1920 through the present, although the name and ownership has changed several times over the course of the 

operational history (Refs. 5, p. 3; 20, pp. 1-3; 21, pp. 1-2). Coke is the residue from the destructive distillation of 

coal (Refs. 14, p. 2; 15, p. 11). BaP is a known contaminant from coke ovens. Arsenic, while also high in local 

soils, is present at high concentrations in the coal from Birmingham and north Alabama, the same coal used in 

many of the coke (Refs. 5, p. 3; 16, p. 4; 17, p. 1; 18). 

Both foundry and furnace coke are produced at the Walter Coke facility (Ref. 20, p. 3). The Walter Coke plant 

currently utilizes 120 coke ovens with a capacity to produce 460,000 tons per year (tpy) of coke (Ref. 20, p. 8). 

Additionally, Walter Coke operates a Utility Plant consisting of four generators that consume coke oven gas and 

natural gas. The principal end user for the power produced at Walter Coke is the Coke Plant. All remaining 

power generated from the Utility Plant is sold back to the local utility provider under a cogeneration agreement 

(Ref. 14, p. 2). 

Thirty-nine (39) Solid Waste Management Units (SWMUs) were identified at the Walter Coke (formerly Sloss 

Industries) facility during a 1989 EPA RCRA Facility Assessment (RFA) and 1996 Geraghty & Miller RCRA 

Facility Investigation (RFI) (Refs. 23, pp. 1, 6-17; 24, p. 17; 25, pp. 1, 8). These 39 SWMUs were separated into 

four separate areas, created to group similar industrial activities together and allow for a systematic 

implementation of the investigation at each area: the Coking Facility, Land Disposal Areas, Biological Treatment 

Facility (BTF) and Sewers, and Chemical Manufacturing Plant (Ref. 25, p. 8). An investigation into the overall 

facility, and each of these identified areas, was implemented in 1995 and continued through at least 2007 (Refs. 

24, p. 17-19; 25, p. 8; 26, p. 1; 27, p. 1; 28, p. 19; 29, pp. 1, 17-18). Further information regarding each waste 

area can be found in References 30, pages 4 through 15. 

In 2010, the Walter Coke facility had two quench towers and one baghouse that were shared between all three 

batteries (Ref. 22, p. 2). The shared baghouse had seven cells consisting of 352 shaker style bags each with one 

hood shared between the batteries (Ref. 22, p. 2). 

The Walter Coke facility’s Title V Air Permit was originally granted on November 21, 2002 (Ref. 22, p. 4). 

Between 1999 and 2000, three violations regarding opacity were recorded at the facility and four violations of the 

source operating permits were identified (Ref. 65, pp. 2-3). An Official Warning was served to the Sloss 

Corporation that continued violations may result in more stringent action (Ref. 65, p. 1). A Settlement 

Agreement, Civil Action No. CV0103322, was entered into on May 25, 2001, between the Jefferson County 

Board of Health (JCBH) and Sloss Industries (aka Walter Coke) Slag Wool Plant as a result of a JCBH complaint 

alleging violations of its Air Pollution Control Rules and Regulations and National Ambient Air Quality 

Standards (NAAQS) for carbon monoxide (Ref. 66, pp. 1-2). Multiple violations were documented in the 2003 

JCDH Full Compliance Inspection, specifically:

Additional Settlement Agreements and several Notices of Violation (NOV), civil penalties and civil actions were 

imposed on Walter Coke between 2000 and 2005 (Refs. 68, pp. 1-3; 69, pp. 4-7).

A 2009 NOV for visible air emissions resulted in a Release Agreement whereby Walter Coke, formerly Sloss 

Industries, paid a fine of $62,000 (Refs. 70, pp. 1-6; 71) 

Historically, the Walter Coke facility treated wastewater generated by its own operations and also received and 

treated wastewater from its Ariton, Alabama facility. In addition, by agreement, wastewater from U.S. Pipe and 

Foundry Company was accepted and treated at the plant (Ref. 72, pp. 1, 2). NPDES Permit No. AL0003247 was 

issued by ADEM on September 29, 1993. The permit authorized the discharge of pollutants and industrial wastes 

to Five Mile Creek. Subsequent to issuance of the NPDES permit in 1993, it was modified by ADEM on January 

31, 1994 and June 16, 1995 (Ref. 72, p. 2). Walter Coke was subsequently cited for numerous permit violations 

and ordered to pay civil penalties as a result (Ref. 72, pp. 1-3). Since the effective date of Consent Order # 02-

214-CWP, 41 additional violations of its NPDES permit were committed (Ref. 72, p. 3). 

On September 13, 2010, ADEM issued an NOV in response to a comprehensive NPDES evaluation indicating 

that Walter Coke discharged pollutants in violation of the limits imposed by Part 1 of its NPDES Permit nine 

times between January 2009 and June 2010 (Ref. 75, pp. 1-8).

ABC Coke

ABC Coke, also known as Birmingham Coke and ByProducts Company [or Birmingham By-Products Coke 

Company (BBCC)]; Alabama By-Products Corporation (ABC); and Drummond Company Inc., ABC Coke 

Division has operated at the facility from 1919 through the present, although the names and ownership have

changed hands several times (Refs. 32, pp. 5-13). Coke is the residue from the destructive distillation of coal 

(Refs. 14, p. 2; 15, p. 11). BaP is a known contaminant from coke ovens, and arsenic, while also high in local 

soils, is present at high concentrations in the coal from Birmingham and north Alabama, the same coal used in 

many of the coke (Refs. 5, p. 3; 16, p. 4; 17, p. 1; 18; 19, p. 1; 106, pp. 12-13; 108, p. 1; 109, p. 2). 

The active ABC Coke facility property, originally 50 acres, is bordered by a railroad and other industrial 

complexes to the east and south, by Five Mile Creek to the North, and a sewage disposal plant and quarry to the 

West (Refs. 3; 31, p. 5; 32, p. 105).

ABC Coke produces foundry coke and furnace coke from three coke oven batteries (Ref. 33, p. 4). The Wilputte 

battery (#1A) has 78 ovens and produces 75% of the total coke; the two remaining Koppers-Becker batteries (#5 

and #6) have 54 ovens and produce the remaining 25% of coke (Refs. 33, p. 4; 34, p. 57). Coal is placed in the 

coke batteries, in the absence of air, at a temperature of approximately 2,100 degrees Fahrenheit (Ref. 33, p. 4). 

The coal breaks down in this destructive distillation process, creating coke oven gas and coke (Ref. 33, p. 4). The 

volatile products from the coal and coal tar derivatives are recovered and separated in the coke by-products 

recovery plant (Ref. 33, p. 4). Listed hazardous waste generated in the coke by-products plant and other solid 

wastes are recycled into the coke ovens using a waste recycling process, called the Kipin process (Ref. 33, p. 4). 

ABC Coke receives waste materials, such as tar decanter sludge, for recycling from the coke by-products plant 

and from facilities in Ohio, New Jersey, and Alabama (Ref. 33, p. 4). Further information regarding processes at 

the ABC Coke facility is located in References 33, pages 4 through 11; 34, pages 57 through 59; and 35, pages 2 

through 4. 

ABC Coke operates a biological wastewater treatment system, including tanks with secondary containment, an 

equalization basin, post aeration basin, and separate storm water runoff basin, whose discharge to Five Mile Creek 

is regulated by an NPDES permit (Refs. 31, p. 3, 5-6, 22; 32, p. 17). An area near Five Mile Creek was used for 

the storage of tar storages, a practice that ended around 1950; coke is stored in this area (Refs. 31, p. 3, 5-6, 22; 

32, pp. 16-17; see also Figure 1 of this HRS documentation record). ABC Coke regularly (at least twice a year) 

removes all sludge and sediments from these ponds and units, dewaters these materials, and recycles them 

through its process (Ref. 32, pp. 17-18). ABC Coke produces foundry coke from three coke oven batteries, all of 

which use coke oven gas for fuel (Ref. 34, p. 57). Factors affecting emissions from the combustion stack include 

incomplete combustion in the flues or cracks in the brickwork between an oven chamber and flue (Ref. 34, p. 58). 

ABC Coke practices periodic silica dusting, the spraying of a silica-containing dust inside an oven before 

charging it with coal (Ref. 34, pp. 58-59). The dust fuses to the silica brick lining the oven and sealing any small 

cracks (Ref. 34, pp. 58-59). Repairs to brickwork, jambs, through-walls and end flues are reportedly conducted as 

needed (Ref. 34, p. 59). 

Water is used to quench the glowing coke (Ref. 32, p. 17). The process consumes water and uses up all water 

internally in the process (Ref. 32, p. 17). The quenching process and the process air emissions are both regulated 

under 40 C.F.R. §§ 63.7280—63.7352, whose requirements are incorporated into the Facility's Title V permit 

(Ref. 32, p. 17). 

ABC Coke’s air emissions were regulated by JCHD since the mid-1970s (Refs. 32, p. 15; 76, pp. 402-404). 

A Major Source Operating Permit in 2003 replaced 22 existing permits (Refs. 32, p. 15; 76, pp. 36-37, 49). The 

2003 Major Source Operating Permit reduced the emissions sources to 14; this permit was replaced in 2008 (Ref. 

32, p. 15; 76, pp. 36-37, 105-107). 

Multiple violations and corrective actions were brought against ABC Coke over its operating history (Refs. 32, p. 

16; 36, pp. 10-12, 759-1116; 79, pp. 1-24; 80, pp. 1-10; 81, p. 1-26). In 1975, legal action was first brought 

against ABC Coke for failure to implement Clean Air Act provisions (Ref. 80, p.161). On October 31, 1980, a 

Consent Decree between the United States of American and ABC Coke was ordered that included detailed 

requirements to control door, standpipe, and charging hole lid emissions (Ref. 80, pp. 295-315). The 1980 

Consent Decree was subsequently modified in 1982 to include schedules for engineering, construction, start-up 

and demonstration of compliance for new boilers and a new pushing emission control system (Ref. 80, pp. 316-

345). The terms of the 1982 Consent Decree expired in 1985; the one exception was that the 20% maximum 

opacity, as established as a standard for pushing emissions in the Consent Decree, remained in effect until 

between 1997 and 1998 (Ref. 80, pp. 155-156, 159). Following a NOV from JCHD citing five observed 

47 
Area Letter: A

 

violations between January 6 and April 22, 1987, a Settlement Agreement was entered in April 1988 that included 

extensive requirements to repair and replace door jambs, door plugs, and valves, as well as demonstrations of 

compliance with Jefferson County Air Pollution Control Rules (Ref. 80, p. 160). In March, 1988, JCDH received 

a letter indicating that after repair and modification of the system, ABC Coke could not meet the 20% opacity 

limits as dictated by the 1982 Consent Decree (Ref. 80, p. 33). Additional violations and complaints were 

received between 1989 and 2005, including a Notice of Violation in 1999 and 2005 (Ref. 80, pp. 12, 23, 45-76, 

98, 102, 117, 119, 157, 254, 290). Multiple violations were also noted with the NPDES permit (Refs. 78, pp. 1-9; 

81, pp. 1-9). A Consent Order was submitted in 2004 by ADEM for exceeding the maximum daily discharge 

limit for BaP 37 times, exceeding the monthly average for BaP four times, and failure to report the daily 

maximum for BaP once, a total of 42 violations (Ref. 81, pp. 271-279). 

U.S. Pipe 

The former U.S. Pipe operated at 3000 30th Avenue North as a pipe foundry from the early 1900s until 2010, with 

ownership and the name changing several times (Refs. 5, pp. 3-5; 37, p.1; 115, p. 10). U.S. Pipe has also been 

known as: Dimmick Pipe Co. (Dimmick); United States Cast Iron Pipe and Foundry Company a/k/a United States 

Pipe and Foundry Company; Jim Walter Corporation; Mueller Water Products, Inc.; and USP Holdings (Refs. 5, 

pp. 3-5; 21, pp. 1-2; 38, pp. 1-9). BaP and lead are known contaminants from foundries (Refs. 5, p. 3; 16, p. 4; 

17; 19, p. 1; 106, pp. 12-13, 22; 108, p. 1; 109, pp. 2, 18; 114, p. 247). 

The approximately 63-acre facility is bounded on the north by 35th Avenue and to the southwest by the 

Birmingham Southern railroad right-of-way (Refs. 3; 40, p. 4). The facility's main entrance was located on 29th 

Avenue North (Ref. 40, p. 4). The former U.S. Pipe originally manufactured pipe using the pit cast method, 

replaced in 1921 by centrifugal casting (Ref. 21, p. 1). Prior to dismantlement, the facility contained a foundry, 

several pipe storage yards for finished products, several treatment ponds, scrap raw material storage, and a closed 

landfill formerly used for disposal of solid waste (Ref. 40, p. 4). Scrap metal, including automobile parts, 

demolition debris from steel tanks, and building materials, was placed into a cupola furnace and heated to 

approximately 3,000 degrees Fahrenheit (°F). Limestone was added to remove impurities from the scrap metal 

mixture and coke was added to fuel the reaction (Ref. 41, p. 10). Together this material formed the cupola furnace 

input or "charge" (Ref. 41, p. 10). While in the furnace, lead, cadmium and other contaminants in the scrap metal 

vaporized and adhered to particulates in the off-gases (Ref. 41, p. 10). Additional details regarding the processes 

at U.S. Pipe are available in Reference 41, pages 13 through 15 and 42, pages 12 through 16. 

Waste products from the facility included approximately 104 tons per day (tpd) of solid waste, consisting of 

baghouse dust and cement-lining materials (Ref. 40, p. 4). Baghouse dust, generally 15-20 microns in size, was 

generated at a rate of 15 tpd and was formed by metal vaporization, reaction of air within the cupola, and 

deposition on condensed nuclei scrap (Refs. 41, p. 13-14; 42, p. 12). Metals such as zinc, lead, and cadmium 

became part of the dust along with dirt normally found in melted scrap (Ref. 42, p. 12). Prior to 1987, the 

baghouse dust contents were disposed in a landfill on the property, where it was spread and mixed with other 

foundry waste (Ref. 42, p. 1, 14). In early 1988, U.S. Pipe began operating a totally enclosed treatment system for 

its baghouse dust whereby the dust was gathered and mixed with a reagent to bind the metals and then disposed of 

at an off-property permitted industrial landfill (Refs. 40, p. 4; 42, pp. 14; 43, p. 66). The contact wastewaters 

were channeled to facility ponds for settling treatment followed by additional settling in the facility’s primary and 

secondary treatment ponds. Water from the secondary treatment pond was pumped to a National Pollutant 

Discharge Elimination System (NPDES) wastewater treatment plant located at another U.S. Pipe plant on 

Huntsville Road in Birmingham (Refs. 44, p. 1; 41, pp. 14-15; 45, p. 3). Additional details regarding the 

wastestreams at U.S. Pipe are available in References 41, pages 13 through 15 and 42, pages 12 through 16. 

48 
Area Letter: A

 

U.S Pipe’s air emissions were regulated by the JCHD since the early 1970s (Ref. 82, p. 2). On July 18, 2001, 

JCDH issued a Title V Major source Operating Permit No. 4-07-0360-01 to U.S. Pipe, which expired on July 19, 

2006, and included 16 permitted emissions units (Ref. 83, pp. 1, 3). On January 30, 2009, U.S. Pipe was issued 

Title V Major Source Operating Permit No. 4-07-0360-02 (Ref. 84, p. 1). 

U.S. Pipe first filed a Hazardous Waste Notification form in 1981 and was assigned EPA ID No. ALD004017901 

(Ref. 85, p. 1). A facility inspection conducted on June 10, 1985 determined that U.S. Pipe had been disposing of 

baghouse dust containing hazardous waste in an on-site landfill (Ref. 86, p. 1). EPA issued U.S. Pipe a Complaint 

and Compliance Order in November 1985 for violations surrounding the on-site landfill (Ref. 87, pp. 1-6). After 

nearly three years of negotiations, in 1988, U.S. Pipe and EPA entered into a Consent Agreement and Final Order, 

in which U.S. Pipe agreed to immediately cease placing untreated baghouse dust in its landfill, develop and 

implement plans for closure and post-closure of the landfill, including periodic ground water monitoring (Ref. 88, 

pp. 1, 6-7). The landfill was certified closed in 1995 (Refs. 89; 90, pp. 8). U.S. Pipe was granted Post-Closure 

Care Permit in 1997, which required U.S. Pipe to perform additional assessment activities in three areas: ground 

water monitoring, interim measures work plan and implementation, and confirmatory sampling work plan and 

implementation (Ref. 91, p. 1). 

Multiple air releases were reported at the U.S. Pipe facility, including malfunctions causing the release of excess 

emissions from as little as 6 minutes to 19 hours, often resulting in opaque emissions (Refs. 92, pp. 1-2; 93, p. 1; 

94, pp. 2-3; 95; 98). Surface water violations were also noted at the U.S. Pipe facility, including the release of 

cement-burdened wastewater, industrial water, and pH 10 water from various ponds (Ref. 99, pp. 1-3). 

Alagasco 

The Alagasco facility, also known as the Blue Mud Facility, operated as the Alagasco gas holder and purification 

system from 1878 until the mid-1900s (Ref. 103, pp. 5, 273). The gas was not manufactured on the property, but 

was further purified and stored; an area behind the Gas Storage Facilities was used as a disposal site for spent 

wood chip filters or “boxes” used to clean the synthetic gas (Ref. 103, pp. 5, 273). The gas supplied to the 

property reportedly may have come from local coking operations conducted at foundries in and around the 

Birmingham area (Ref. 103, p. 5). The conversion from coke oven gas to natural gas occurred at this location 

between 1950 to 1955, and afterwards it served as a gas holder and distribution facility, until the gas holder 

operations were discontinued and the gas holder dismantled in 1985 (Ref. 103, p. 5). The dominant chemical 

used in the spent filters was Prussian Blue, or ferric ferrous cyanide, imparting a bright blue color to the soil at the 

property (Ref. 103, pp. 10-11, 273). The property was also used an unofficial dump; buried debris and numerous 

bottles were discovered over the years (Ref. 103, p. 273). The location became the Birmingham District 

Distribution Control Center until those operations were moved in September 1999 (Ref. 103, p. 6). 

In 1980, Alabama Gas Corporation was notified that sampling at the property, referred to as the Birmingham 

Disposal Site, had indicated low pH water, containing cyanide and arsenic, was intermittently flowing from the 

area to a nearby ditch (Ref. 103, p. 459-461). Arsenic and lead were also detected in sludge collected from the 

property during the same year (Ref. 103, p. 470). 

An area was excavated in 1982, with a large amount of the blue soil and clay excavated, the excavated area filled 

with lime, and the original soil material returned to the hole with new fill material from off the property (Ref. 103, 

pp. 273, 626-645). 

In 1997, an environmental and geotechnical Site Assessment was conducted at the facility to evaluate the property 

for future land use (Ref. 103, pp. 279-281). According to the report, a number of PAHs, metals and total cyanide 

49 
Area Letter: A

 

were detected at elevated concentrations on the property, with the possibility of an unacceptable risk of direct 

exposure to soil (Ref. 103, p. 284). Specifically, BaP, arsenic, and lead were all detected in soils located on the 

property (Ref. 103, p. 301). 

In 1998, a sampling investigation was conducted to determine if the cyanide had migrated off the property (Ref. 

103, p. 273-274). Trace metals were detected in the monitoring wells, as well as cyanide in the surface water and 

sediment samples (Ref. 103, p. 274). However, as there were no target populations, and the soil was scheduled to 

be capped, no further evaluation was recommended (Ref. 103, p. 276). 

Alabama Gas Corporation was authorized by NPDES permit to discharge to Village Creek, located south of the 

35th Avenue AOC, effective February 4, 1985, and expiring February 4, 1986 (Ref. 103, p. 827). 

 

Attribution Conclusion

Due to the duration of deposition, likely overlapping releases within the AOC, and number of contributors, the 

EPA has determined that there is insufficient data to define the extent of the contribution from any industry in the 

area. Therefore, a commingled area of observed soil contamination has been identified at this site (Ref. 100, p. 1-

13; see Figure 2 and the tables in section 5.0.1 of this HRS documentation record). The AOC includes 

commingled soil contamination likely resulting from the emissions of nearby industrial operations (e.g., Walter 

Coke, ABC Coke and U.S. Pipe); numerous other possible contributors have been identified in and around the 

35th Avenue site area. An industrial survey prepared by Walter Coke identified 76 distinct facilities in seven 

industries that Walter Coke claimed were associated with both metals and PAHs (Ref. 7, pp. 12-14). The AOC is 

likely a result of a combination of air deposition, physical transfer of contaminated waste solids from the 

industries by residents, and the deposition from flooding downstream of NPDES outfalls. This conclusion is 

based on the following: 

(1) The operational history of the industries listed above; 

(2) The presence of lead, benzene compounds, and arsenic in air studies;

(3) The presence of lead, BaP, and arsenic in sediments along Five Mile Creek (Ref. 111, p. 23) 

Uneven spatial distribution of contaminants within the AOC is likely due to the length of time since initial 

contamination deposition, variations in wind and weather patterns, and the proximity to Five Mile Creek (Refs. 3; 

100, pp. 1-13). In the 100-plus years since operations began in the area, many of the residential yards have been 

disturbed by landscaping, sidewalk placement, gardening, and even total redevelopment. Additionally, the 

historical wind direction for the 5-year periods between 1950-1955, 1970-1975, 1990-1995, and 2008-2013 

indicates considerable wind variability in the area (Ref. 100, pp. 1-5). This data further supports the aerial 

deposition and commingling of lead, arsenic, and BaP contamination in the soil within the AOC from multiple 

likely and possible contributors.

AREA HAZARDOUS WASTE QUANTITY

- Hazardous Constituent Quantity:

The Hazardous Constituent Quantity for AOC A could not be adequately determined according to the HRS 

requirements; that is, the total mass of all CERCLA hazardous substances in the source and releases from the 

source is not known and cannot be estimated with reasonable confidence (Ref. 1, pp. 51590-51591 [Section 

2.4.2.1.1]). Insufficient historical and current data [manifests, potentially responsible party (PRP) records, State 

records, permits, waste concentration data, etc.] are available to adequately calculate the total mass of all 

CERCLA hazardous substances in the source and the associated releases from the source. Therefore, there is 

insufficient information to calculate the Hazardous Constituent Quantity for AOC A with reasonable confidence.

Hazardous Constituent Quantity Assigned Value: Not Scored

- Hazardous Wastestream Quantity:

The Hazardous Wastestream Quantity for AOC A could not be adequately determined according to the HRS 

requirements; that is, the total mass of all hazardous wastestreams and CERCLA pollutants and contaminants for 

the source and releases from the source is not known and cannot be estimated with reasonable confidence (Ref. 1, 

p. 51591 [Section 2.4.2.1.2]). Insufficient historical and current data (manifests, PRP records, State records, 

permits, waste concentration data, annual reports, etc.) are available to adequately calculate the total mass of all 

hazardous wastestreams and CERCLA pollutants and contaminants for the source and the associated releases 

from the source. Therefore, there is insufficient information to adequately calculate or extrapolate the Hazardous 

Wastestream Quantity for AOC A with reasonable confidence.

Hazardous Wastestream Quantity Assigned Value: Not Scored

- Volume:

The volume for AOC A could not be adequately determined according to the HRS requirements because 

insufficient historical and current waste sampling data are available to adequately calculate the volume of the 

source with reasonable confidence (Ref. 1, p. 51591 [Section 2.4.2.1.3]). Insufficient historical or current 

sampling data are available to adequately estimate the depth of waste material within the source. Therefore, there 

is insufficient information to adequately calculate or estimate the volume for AOC A.

Volume Assigned Value: 0

- Area:

The AOC is defined by the contamination presented in the above tables. Because of some possible removal 

activities not included in the scoring, or disturbances such as roads, other possible removal actions, etc. that have 

not been quantified, EPA has not inferred contamination between locations for the hazardous waste quantity 

measurement or scoring purposes; therefore, an area measure has not been made for the AOC. The Area for the 

AOC is undetermined but greater than zero.

5.1 RESIDENT POPULATION THREAT

5.1.1 LIKELIHOOD OF EXPOSURE

All samples within the AOC containing arsenic, lead, or BaP concentrations equal to or greater than 3 times the 

applicable background level meet observed contamination criteria as defined by the HRS (Ref. 1, Sections 2.3 and 

5.0.1). Release samples were compared to the highest value background containing the same number of aliquots 

for each composite sample, from a similar depth, similar property type, and compared to sieved or non-sieved as 

appropriate. All samples were collected using the same sampling protocol and analyzed using the same analytical 

methods (Ref. 4, pp. 4-5, 8-9; 6, pp. 12-15; 16, pp. 6, 28-29; 63). All background samples were conducted in 

accordance with EPA SESD Field Branches Management and Quality System Procedure and using the SESD 

field measurement and sampling operating procedures (Ref. 16, p. 28). Background soil samples were analyzed 

according to EPA Analytical Support Branch Laboratory Operations and Quality Assurance Manual, January 

2010 (Ref. 16, p. 29). The samples were analyzed according to EPA method SW-846 8270D, 200.8, and 6010 

(Refs. 4, p. 19; 16, p. 29). Contaminated samples were collected in accordance with the EPA Region 4 Field 

Branches Quality System and Technical Procedures (FBQSTP) and the site-specific QAPP/SSP approved on 

October 18, 2012, and were submitted to a NELAC Institute certified laboratory, either Spectrum Laboratory of 

Tampa, Florida, or TestAmerica Laboratories, Inc., of Savannah, Georgia and Tampa, Florid, for sample analysis 

(Ref. 6, pp. 8, 14-15). Contaminated soil samples were analyzed for semi-volatile organic compounds (SVOCs) 

using EPA Method SW846-8270D and metals using SW846-6010/7471 (Ref. 4, p. 19). Data were validated 

according to the USEPA Contract Laboratory Program (CLP) National Functional Guidelines (NFG) for Organic 

Methods Data Review dated October 1999, USEPA CLP NFG for Low Concentration Organic Methods Data 

Review dated June 2001, and USEPA CLP NFG for Inorganic Data Review dated October 2004 (Ref. 6, p. 15). 

Residential property boundaries and sample locations were plotted in the field logbooks and also recorded with 

global positioning system (GPS) coordinates during sampling events (Ref. 62, p. 8). Some of the sample 

locations were not manually measured from the residence in the field. In these instances, the property boundaries 

were obtained electronically, and the distance from the residence to the farthest aliquot was measured using the 

Geographic Information System (GIS) program to provide the evidence that the samples were within 200 feet of 

the home (Ref. 63, pp.1-4). Therefore, all properties whose soil sample analytical results indicate arsenic, lead, or 

BaP contamination meet observed contamination criteria. For all samples presented below, the sample 

documenting observed contamination is on the property of and within 200 feet of a residence. Thus, a likelihood 

of exposure factor category value of 550 was assigned in accordance with the HRS (Ref. 1, Sections 5.1 and 5.1.1, 

p. 51646). Those properties undergoing removal actions have not been included in this list (Ref. 112, pp. 1-4).

The samples listed below, and shown in Figure 2 of this HRS documentation record, meet the requirements for 

establishing observed contamination.

5.1.3.1 Resident Individual

Area Letter: A

Level of Contamination (Level I/Level II): I

As previously stated in this HRS documentation record, the samples were collected from depths of 0 to 4 inches 

bgs (Refs. 4, p. 9; 6, pp. 12-14; 62, p. 6). Because properties in the AOC are less than 200 feet in length and 

width, all residential properties where analytical results indicate arsenic, BaP, or lead contamination significantly 

above background level have residents living less than 200 feet from the AOC (confirmed by samples presented 

in Section 5.1.1 of this HRS documentation record). There are no health-based benchmarks for lead in the soil 

exposure pathway, therefore only those properties with arsenic or BaP above applicable benchmarks were 

considered for resident individual and Level I resident population evaluation, a total of 97 properties (confirmed 

by the table in Section 5.1.3). 

Resident Individual Factor Value: 50

Level I Resident Population Targets

All residents located on the property of and within 200 feet of a sample within the AOC documenting arsenic 

and/or BaP contamination at concentrations equal to or greater than the Cancer Risk Screening Concentration 

(CRSC) for the soil exposure pathway qualify as Level I targets. A total of 97 residential properties have samples 

exceeding the CRSC benchmark and are therefore considered subject to Level I concentrations. The average 

number of persons per household in Jefferson County is 2.48, resulting in a total of 240.56 individuals subject to 

Level I concentrations (97 households x 2.48 persons per household = 240.56 individuals) (Refs. 1, Section 

5.1.3.2, p. 51647; 101, p. 1).

Sum of individuals subject to Level I concentrations: 240.56

Sum of individuals subject to Level I concentrations x 10: 2,405.6
