500001 DECLARATION STATEMENT RECORD OF DECISION

SITE NAME AND LOCATION

Welsbach and General Gas Mantle Contamination Site (EPA ID# NJD986620995) Camden and Gloucester City, Camden County, New Jersey Operable Unit 3

STATEMENT OF BASIS AND PURPOSE

This decision document presents the selected no action remedy for the surface water, sediment, and wetland areas in the Welsbach and General Gas Mantle Contamination site (Welsbach Site) study area in Camden and Gloucester City, New Jersey. This remedy was chosen in accordance with the Comprehensive Envirormiental Response, Compensation, and Liability Act of 1980 (CERCLA), as amended, and, to the extent practicable, the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). This decision is based on the Administrative Record file for this site. The State of New Jersey concurs with the selected no action remedy.

DESCRIPTION OF SELECTED REMEDY

The selected no action remedy described in this docimient applies to the third of foiu- plaimed operable tmits for the Welsbach Site. The U.S. Enviroimiental Protection Agency (EPA), in consultation with the State of New Jersey, has determined that no site-related contaminants of potential concem are present at elevated levels in the surface water, sediment, and wetland areas in the Welsbach Site study area. Therefore, no remedial action is warranted, because there is no radiological contamination in the surface water, sediment, and wetland areas in the Welsbach Site study area that poses an unacceptable risk to human health or the environment.

On July 23, 1999, EPA, with support from New Jersey Department of Environmental Protection (NJDEP) selected a remedy for Operable Unit 1 (GUI) at the Welsbach Site, and identified three additional planned operable imits. The QUI remedy included demolition of the former General Gas Mantle Company (GGM) building; excavation of the radiologically contaminated soil and debris at the residential, commercial, and industrial properties at the Welsbach Site; and disposal of this material at a licensed off-site facility. Additional operable units will address potential remedies for the former Welsbach-era building knovsTi as the Armstrong Building (Operable Unit 2), and the groimdwater (Operable Unit 4).

DECLARATION OF STATUTORY DETERMINATIONS

In accordance with the requirements of CERCLA and the NCP, EPA has determined that no remedial action is necessary for the third operable unit (0U3) of the Welsbach Site to ensure protection of human health and the environment.

500002 The primary contaminants at the Welsbach Site are radionuclides in the and uraniimi decay chains and their decay products. Although the levels of some chemical contaminants of potential concem exceeded the ecological guidelines and human health risk levels in the surface water, sediment, and wetland areas in the Welsbach Site study area, these chemical contaminants are not related to operations associated with the Welsbach Company or the GrGM Company.

EPA is aware that NJDEP periodically collects samples of edible fish and shellfish in water bodies throughout the state. NJDEP has fotmd elevated levels of merciuy, dioxins, and polychlorinated biphenyls (PCBs) in its Delaware River samples. Furthermore, NJDEP established fish consumption advisories to address the elevated levels of PCBs and other chemical contaminants in fish from the Delaware River and its tributaries. EPA recommends that people fishing in the area follow the appropriate fish consiunption advisories.

500005 SITE NAME, LOCATION, AND DESCRIPTION

The Welsbach/General Gas Mantle Contamination site (Welsbach Site) is a multi-property site centered aroimd two former thoritim gas mantle manufacturing companies in the cities of Gloucester City and Camden, New Jersey. Approximately 100 residential, commercial, and industrial properties make up the Welsbach Site. The Delaware River, Newton Creek, and Martins Lake are adjacent to some of these radiologically contaminated properties. This Record of Decision (ROD) addresses surface water, sediment and wetland areas associated with these water bodies in the Welsbach Site study area.

The U.S. Enviroimiental Protection Agency (EPA) has divided the Welsbach Site into four separate cleanup phases, or operable units. On July 23,1999, EPA, with support from the New Jersey Department of Environmental Protection (NJDEP) selected a remedy for the radiologically cpntaminated soils at the Welsbach Site. The remedy for this first Operable Unit 1 (OUl) included demolition of the former General Gas Mantle Company (GGM) building, excavation of the radiologically contaminated soil and debris at the residential, commercial, and industrial properties at the Welsbach Site, and disposal of this material at a licensed off-site facility. The third Operable Unit 3 (0U3) includes the surface water, sediment and wetland areas in the Welsbach Site study area. Additional operable units will address potential remedies for the former Welsbach-era building known as the Armstrong Building (Operable Unit 2), and the groimdwater (Operable Unit 4).

SITE HISTORY AND ENFORCEMENT ACTIVITIES

Site Background

Between the 1890s and 1940s, the Welsbach Company (Welsbach) manufactured gas mantles at its facility in Gloucester City, New Jersey. Welsbach was a major manufacturer and distributor of gas mantles vmtil the electric hght replaced gas hghting. Beginning aroimd 1895, Welsbach imported ore to use as its source of the radioactive element thorium. Welsbach extracted thorium from the ore and used it in its gas mantle manufacturing process. Thorium causes the mantles to glow more brightly when heated. Just after the turn of the century, Welsbach was the largest producer of gas mantles and lamps in the United States, making up to 250,000 mantles per day. Welsbach went out of business in 1940.

A second gas mantle manufacturing company, GGM, located in Camden, New Jersey, was a small competitor to the Welsbach Company. GGM operated from 1912 to 1941. There is little information on its iactivities. It appears that GGM only used refined thorium in its gas mantle manufacturing processes.

EPA initially identified the Welsbach Site in 1980 during an archive search conducted as part of an investigation of the U.S. Corporation Superfimd site located in Orange, New Jersey. Historical U.S. Radium Corporation files indicated that U.S. Radium purchased radiological materials from Welsbach during the 1920s. In May 1981, EPA sponsored an aerial radiological survey of the Camden and Gloucester City area. The survey covered a 20-square-kilometer area surrounding the locations of the former Welsbach and GGM facilities. NJDEP evaluated the data from the aerial survey and identified five areas with elevated gamma radiation levels. The

500006 elevated areas included the locations of the two former gas mantle manufacturing facilities and three mainly residential areas in both Camden and Gloucester City. In 1993, EPA re-analyzed the data from the aerial survey, which subsequently led to the identification of a sixth area, located in Gloucester City, with elevated gamma radiation levels (See Figure 1.)

A description of each Study Area follows:

• Study Area 1 - includes the former GGM facihty and residential and commercial properties that surround the facihty. The former GGM facihty is located in a mixed industrial, commercial, and residential section of Camden.

• Studv Area 2 - includes the location of the former Welsbach facihty and nearby residential/commercial properties. The former Welsbach facility is located in an industrially zoned section of Gloucester City with residential properties immediately to the east. An original Welsbach building, the Aimsfrong building, is still present on the property.

• Study Area 3 - includes residential and recreational properties in Gloucester City, including the Gloucester City Swim Club and the Johnson Boulevard Land Preserve.

• Study Area 4 - includes residential properties in the Fairview section of Camden.

• Studv Area 5 - includes residential properties, vacant land, and two municipal parks near Temple Avenue and the South Branch of Newton Creek in Gloucester City.

• Study Area 6 - includes vacant lots in a residentially zoned area of Gloucester City.

• Surface Water, Sediment and Wetland Investigation Areas - EPA conducted the investigation of surface waters, sediments and wetlands in Study Areas 1,2, 3, 5, and 6 of the Welsbach Site. EPA did not include Study Area 4 in this investigation because the soil contamination in this area is in very small and isolated locations.

In the early 1990s, NJDEP conducted follow-up radiological investigations at more than 1,000 properties located throughout the original five Study Areas. During these investigations, NJDEP identified radiological contamination at the two former gas mantle facilities and at residential, commercial, and industrial properties located near the two facihties. Based on these data, NJDEP conducted some interim remedial measures which included installing concrete, steel, and/or soil shielding inside homes and yards, installing mitigation systems at selected properties, and relocating one resident and one business.

In March 1995, EPA prepared a Hazard Ranking System (HRS) report for the Site, and in June 1996, EPA placed the Welsbach Site on the National Priorities List (NPL). EPA, as the lead agency, prepared this decision document with support from NJDEP. Site-related activities are being federally fimded.

From September 1997 to January 1999, EPA conducted a remedial investigation and feasibility study (RI/FS) to investigate the radiological contamination at a number of residential and 500007 industrial properties at the Welsbach Site. On July 23,1999, EPA signed a ROD for OUl (1999 ROD). EPA stated in the 1999 ROD that it would address the potential site impacts to surface water, sediment, and wetland areas in the fiiture.

In April 2001, EPA started the surface water, sediment, and wetland investigation called for in the 1999 ROD. The results of this study can be found in the Screening Level Ecological Risk Assessment Report (March 2002). In January 2005, EPA used sediment data from the surface water, sediment, and wetland investigation to evaluate the baseline human health risk from radionuclides and chemicals of potential concem (Human Health Risk Assessment Addendum, January 2005).

As part of the design investigations for OUl, EPA has investigated nearly 1,000 properties in the Camden and Gloucester City area. Based on information from this investigation, EPA has identified approximately 100 residential, commercial, and industrial properties with elevated radionuchde levels. EPA has completed cleanup activities on over 15 residential properties, a portion of the Gloucester City Swim Club, and the Popcorn Factory property in Study Area 6. At present, EPA is continuing its cleanup efforts on other residential properties in the Gloucester City and Camden area.

Enforcement History

Both Welsbach and GGM went out of business in the early 1940s. To date, EPA has been unable to identify any successor companies.

In September 1997, Holt Hauling and Warehousing, Inc. (Holt), which owned the former Welsbach property at that time, entered into an Adminisfrative Order on Consent (AOC) with EPA. Under the terms of the AOC, Holt agreed to perform an RI/FS on the Aimsfrong Building (the one remaining original Welsbach building). In January 2000, Holt submitted the RI/FS Report for EPA review and approval. Holt's RI/FS identified sporadic radiological contamination on the structural surfaces inside the building. In July 2000, EPA approved Holt's RI/FS Report, and will select a remedy for the Aimsfrong Building in the fiiturebase d on information obtained from Holt's RI/FS.

HIGHLIGHTS OF COMMUNITY PARTICIPATION

EPA has worked closely with public officials and other interested members of the Gloucester City and Camden communities. Their participation and contributions to the site investigation and remediation process have benefited and continue to benefit the Agency in achieving its goal of effectively protecting human health and the environment.

The Proposed Plan and supporting documentation were released to the public for comment on May 24,2005. These documents were made available to the public at:

• The EPA Adminisfrative Record File Room, 290 Broadway, 18th Floor, New York, New York 10007.

• City of Camden Main Library, 418 Federal Sfreet, Camden, New Jersey 08103.

3 500008 • The Hynes Center, 1855 South 4th Sfreet, Camden, New Jersey 80104.

• The Gloucester City Pubhc Library, Monmouth and Hudson Sfreets, Gloucester City, New Jersey 08030.

The initial pubhc comment period was held from May 24 through June 23, 2005. However, at the request of the NJDEP, EPA extended the public comment period to August 2, 2005. Notices of availability for the documents in the adminisfrative record were published in the Courier-Post on May 24, 2005, and July 25,2005. EPA held two public meetings to present the preferred no action remedy for 0U3. The first meeting was held on June 8,2005, at the Welsbach Field Office, and the second meeting was held on July 26, 2005, at the Camden County Municipal Utilities Authority. The purpose of these meetings was to inform local officials and interested citizens about the Superfimd process, to discuss the Proposed Plan and receive comments on the Proposed Plan, and to respond to questions from area residents and other interested parties. Responses to the comments received at the pubhc meetings and in writing during the pubhc comment period are included in the Responsiveness Summary, attached as Appendix FV to this ROD. SCOPE AND ROLE OF OPERABLE UNIT

The decision described in this document relates to the third of four planned operable units at the Welsbach Site. The July 1999 ROD addressed OUl, and specified the demolition of the foimer GGM building, excavation of the radiologically contaminated soil and debris at the residential, commercial, and industrial properties at the Welsbach Site, and disposal of this material in a hcensed off-site facility.

This ROD addresses 0U3, the surface water, sediment, and wetland areas in the Welsbach Site study area. Based on the findings in the Screening Level Ecological Risk Assessment and the baseline Hiunan Health Risk Assessment Addendum reports, the surface water, sediment and wetland areas do not pose an unacceptable risk to human health or the environment for site- related contaminants. Additional operable units will address potential remedies for the former Welsbach-era building known as the Armsfrong Building (0U2), and the groundwater (0U4).

SITE CHARACTERISTICS

As discussed above, the Welsbach Site is a multi-property site that is centered around two former thorium gas mantle manufacturing companies, Welsbach, located in Gloucester City, and GGM, located in Camden. According to the 2000 census data, approximately 11,500 and 79,900 people live in the cities of Gloucester City and Camden, respectively.

Site Area Drainage

The Welsbach Site is located on the westem edge of the Atlantic Coastal Plain in New Jersey in the Delaware River drainage basin. Drainage from the six Study Areas flows into the following water bodies: Newton Creek, including its North and South Branches, the Delaware River, and Martins Lake. The three forks of Newton Creek ultimately flow into the Delaware River. Martins Lake is an isolated water body about a third of an acre in size located in Study Area 5.

. 500009 Newton Creek and its South Branch generally flow west-northwest, and the Delaware River generally flows south. These surface waters are tidal.

In Study Area 1, runoff water from rain events flows into the Delaware River though the municipal storm sewer system. In the basement of the former GGM building, there were underground drains that connected to the municipal storm sewer system.

In Study Area 2, runoff from the residential site properties and a portion of the former Welsbach property flows into the Delaware River through municipal storm sewers. The remainder of the overland runoff of water from the former Welsbach property is comprised of sheet flow (runoff that does not follow a defined chaimel) that flows directly into the Delaware River or Newton Creek.

In Study Area 3, runoff flows into Newton Creek through municipal storm sewers or as sheet flow.

In Study Area 4, runoff flows into either Newton Creek or the North Branch Newton Creek. The runoff from the residential site properties flows into the creeks through municipal storm sewers. Because the radiological contamination in this Study Area is located in very small isolated areas, the water bodies with runoff from this Study Area were not included in the ecological assessment.

In Study Area 5, runoff flows into either the South Branch Newton Creek or Martins Lake. Runoff flows into Newton Creek either through municipal storm sewers or as sheet flow along the surface. A portion of the overland flow from Martins Lake Park empties into Martins Lake.

In Study Area 6, runoff flows into either the Delaware River or Little Timber Creek through storm sewers or as sheet flow.

Surface Water, Sediment, and Wetland Investigation

In April and May 2001, EPA conducted a surface water, sediment, and wetland investigation in five of the six Study Areas in the Welsbach Site study area. The main objectives of this investigation were:

• To determine the presence or absence of radiological contamination in the bottom sediments of the water bodies where on-shore deposits of site-related radiologically contaminated materials were known or suspected.

• To prepare a screening level ecological risk assessment for the radiological and chemical contaminants of potential concem.

• To assess baseline risk to human health and the enviromnent from radionuclides in the surface water, sediment, and wetland areas.

• To provide sufficient data to make either a "no further action" recommendation or recommendations for fiirther studies.

5 500010 EPA conducted the investigation of surface waters, sediments and wetlands in Study Areas 1,2, 3, 5, and 6 of the Welsbach Site. EPA did not include Study Area 4 in this investigation because the soil contamination is in very small and isolated areas.

The investigation included collecting sediment samples and measuring the water quality in Newton Creek, the South Branch Newton Creek, Martin's Lake, and several storm water outfalls in South Branch Newton Creek and the Delaware River. EPA collected 154 sediment samples and 82 water quality measurements. Both radiological and chemical data were collected. EPA collected samples from seven sampling area fransects and 10 storm water outfall locations (See Figure 2).

Since the radionuclides of potential concem also occur naturally, EPA collected ten backgroimd sediment samples from five locations upsfream of the Welsbach Site in Newton Creek and South Branch Newton Creek, as well as in North Branch Newton Creek, Little Timber Creek and Miller's Lake (See Figure 3).

Investigation Results

For the radionuclides of potential concem, the radionuchde concenfrations in the sediments were, on average, equal to levels found in uncontaminated areas in the vicinity of the Welsbach Site (background levels). The average radionuchde concenfrations for thorium and radium in both the sediment and background samples were less than 1.2 picoCuries per gram (pCi/g.)

EPA used the data from the ecological investigation to develop the human health and the screening level ecological risk assessments for 0U3, as described below. Because the data requirements for each of these risk assessments were different, EPA separated the results of the investigation. Table 1.1 presents a summary of the sampling results for the human health risk assessment and Table 5 presents a summary of the sampling results for the screening-level ecological risk assessment.

At all of the sediment sampling locations, EPA detected non-radiological chemical constituents that exceeded the maximum background concenfrations and sediment screening guidelines. These chemicals consisted primarily of polycyclic aromatic hydrocarbons (PAHs), pesticides, and PCBs. However, these chemicals are not site-related. Neither Welsbach nor GGM used these chemicals in their manufacturing processes. In addition, many of these chemicals (e.g., PCBs) were not in common use until after both companies went out of business.

As part of a statewide program, NJDEP periodically collects samples of edible fish and shellfish in water bodies throughout the state. NJDEP found elevated levels of mercury, dioxins, and PCBs in its Delaware River samples. As a result, NJDEP issued fish consumption advisories for fish and shellfish from the Delaware River in the area of the Welsbach Site. This advisory is based on concenfrations of mercury, dioxins, and PCBs in fish. Furthermore, NJDEP has issued a prohibition on fish consumption from the Delaware River and its tributaries in the area of the Welsbach Site because of possible Escherichia coli {E.coli) bacterial contamination. Many of the sewer pipes in the area are combined sewer and storm water, with the overflows going directly to the local water bodies. 500011 CURRENT AND POTENTIAL FUTURE LAND AND RESOURCES USES

The Welsbach Site properties and the surrounding areas consist of industrial, commercial, and residential zoning districts. Study Area 1 is located in an industrial-zoned section of Camden with residential properties east of the foimer GGM facility. In Study Area 2, the former Welsbach Facility is situated in an industrial-zoned section of Gloucester City with residential properties to the immediate east. Study Area 3 consists of residential properties, a private swim club, and a land preserve. Study Area 4 consists entfrely of residential properties. Residential properties and two municipal parks comprise Study Area 5. Study Area 6 consists of residential properties and vacant land in a residential area. The Gloucester City Board of Education planned to build a new middle school on the vacant land in the area, including the former Popcom Factory parcel.

No significant changes in land use are anticipated, except in the area of the former GGM facility where some residential areas may be rezoned for commercial uses. The former GGM facihty was bordered by residential homes located on Arlington Sfreet in Camden. At the time of the 1999 ROD, most of the homes on Arlington Sfreet were abandoned and there was debate within the community, given the industrial nature of the area, whether to rezone this area to allow for commercial development or leave it residential. In 2004, the City of Camden demolished the homes on Arlington Sfreet to make way for fiiture commercial use of the property. EPA removed the radiological soil contamination adjacent to the homes and alleyways, removed the building foundations, and backfilled the area with clean fill.

The State of New Jersey classifies Newton Creek and the South Branch Newton Creek as "fresh water - non-frout" (FW2-NT). The State has also classified Martins Lake as FW2-NT. The FW2-NT water classification refers to fresh waters that are generally not suitable for front because of the waters' physical, chemical or biological characteristics, but are suitable for a wide variety of other fish species. Designated uses of FW2-NT waters include: maintenance, migration, and propagation of the natural and estabhshed plant and animal life; primary and secondary contact recreation; industrial and agricultural water supply, and public potable water supply after freatment.

The State of New Jersey classifies the portion of the Delaware River adjacent to Study Area 2 as "Zone 3." Designated uses for Zone 3 include agricultural, industrial and pubhc water supply after freatment; maintenance of resident fish and other aquatic life; migration offish; secondary contact recreation; and navigation. EPA anticipates no significant changes to the classifications of the Delaware River, Newton Creek or Martins Lake.

SITE RISKS

As part of the risk assessment process, EPA looks at the risks posed by a site to both human health and the environment. EPA's risk assessment guidance calls for EPA to consider risk from all radiological and other chemical contaminants of potential concem regardless of whether they are site related. Based on the sediment sampling data from the surface water, sediment, and wetland areas in the Welsbach Site study area, EPA conducted both baseline human health and screening level ecological risk assessments.

n 500012 1999 ROD Human Health Risk Assessment

In the 1999 RI/FS, EPA assessed the potential risk to human health from the radiological contamination in soil at the Welsbach Site. The exposure pathways EPA considered were exposure to extemal gamma radiation and the inhalation and ingestion of radionuclides. The potential receptors of concem were workers, frespassers, and resident adults and children. EPA found that there was unacceptable risk to human health for each of the potential receptors of concem for all of the exposure pathways.

In the 1999 ROD, EPA addressed these risks to human health by selecting a remedy to remove the radiologically contaminated soil and dispose of it at an off-site, licensed facihty. The 1999 ROD also recommended that EPA evaluate current and potential future risk to human health and the envfronment from radionuchdes in surface water, sediment, and wetland areas at a later date.

OU3 Risk Assessment

As discussed above, EPA detected non-radiological chemical constituents in the sediments that exceeded the maximum background concenfrations and sediment screening guidelines. However, EPA determined that these chemicals are not related to the operations of Welsbach or GGM. Since radionuclides are the only site-related constituents foimd in the soils in the Welsbach Site study area, only radiological risks are discussed in the following sections.

Summary of Baseline Human Health Risk Assessment

The baseline human health risk assessment evaluated both current and fiiture cancer risks to young children (0 to 6 years), adolescents (10 to 18 years old), and adults (19 years and older) in the absence of any remedial action and institutional confrols. EPA developed the human health risk assessment using current EPA policy and guidance. A detailed discussion of the data collected and analyzed in this assessment can be found in the Human Health Evaluation: Chemical and Radiological Contaminants in the Delaware River, Newton Creek, and Martin's Lake - Addendum to the Draft Final Remedial Investigation/Feasibility Study Report, January 1999 (Malcolm Pimie, 2005) and the Screening Level Ecological Risk Assessment (March 2002).

EPA uses a four-step process for assessing quantitative human health cancer risks for a reasonable maximum exposure (RME) scenario:

• Data Evaluation or Hazard Identification - identifies the contaminants of potential concem at the site based on several factors such as toxicity, frequency of occuirence, and concenfration.

• Exposure Assessment - estimates the magnitude of actual and/or potential human exposures, the frequency and duration of these exposures, and the pathways (e.g., ingesting contaminated fish) by which humans are potentially exposed.

500013 • Toxicity Assessment - determines the types of adverse health effects associated with chemical exposures, and the relationship between magnitude of exposure (dose) and severity of adverse effects (response).

• Risk Characterization - summarizes and combines outputs of the exposure and toxicity assessments to provide a quantitative assessment of site-related cancer risks.

Data Evaluation: In this step, EPA identified the nature and extent of radiological contamination in environment at the site, such as sediment and fish. EPA selected the contaminants of potential concem in various media {i.e., sediment) based on such factors as toxicity, frequency of occurrence, and fate and fransport of the contaminants in the environment, concenfrations of the contaminants in specific media, mobility, persistence, and bioaccumulation. EPA used simplistic fate and fransport models to evaluate the radionuclides of potential concem (ROPCs) in animal tissue {i.e., fish) associated with the water bodies identified above. The models exfrapolated contaminant concenfrations from sediment to pore water and then to fish. Table 1.2 presents a summary of the predicted contaminant concenfrations in animal (fish) tissue. EPA then used these predicted contaminant concenfrations in the exposure calculations to estimate potential cancer risks. This health protective approach may have resulted in an overestimation of potential cancer risks.

Exposure Assessment: Exposure assessment evaluates pathways by which people are or can be eixposed to the contaminants of potential concem in different media {i.e., sediment). Factors relating to the exposure assessment include, but are not limited to, the concenfrations that people are or can be exposed to and the potential frequency (number of days per year) and duration of exposure (number of years). Table 2 provides the rationale for inclusion or exclusion of potential exposure pathways. EPA identified three pathways of concem; two relating to sediment exposure (ingestion and extemal radiation) and the other to fish ingestion.

Factors relating to the exposure assessment include, but are not limited to, the concenfrations that receptors might be exposed to, and the potential frequency and duration of exposure. The Exposure Point Concenfrations for ROPCs in sediment and fish, as presented in Tables 1.1 and 1.2, were calculated using a 95% Upper Confidence Limit on the arithmetic mean where adequate data were available to support the statistical calculation. EPA used the maximum detected concenfration when adequate statistical information was not availabl/e. EPA's ProUCL Version 3.0 software was used to perform the statistical calculations.

EPA also evaluated exposures to RME individuals. These individuals are regarded as having activity patterns {i.e., fishing) that would bring them into contact with the water bodies more frequently than average individuals. As such, this exposure assessment evaluated current/fiiture . RME child, adolescent, and adults who may recreate in, or consume fish from, the water bodies.

Sediment Exposure. Adolescent exposures were evaluated from direct contact {i.e., incidental ingestion and extemal radiation) with sediment at the water bodies. EPA assumed that adolescents would recreate at the various water bodies for 35 days/year (equivalent to about one day a week over the course of about a nine-month fishing season). EPA also assumed an adolescent ingestion rate of 50 milhgrams per day (mg/day) of sediment and a bodyweight of 60 kilograms (kgs). EPA did not evaluate the

9 500014 potential for exposure to a young child and an adult because these individuals are less likely to frequent the water bodies than an adolescent. Therefore, resulting cancer risks for a young child and an adult would be less than those for an adolescent.

Fish Ingestion. Using the modeled fish concenfrations, EPA evaluated the fish ingestion pathway for young children, adolescents, and adults using the standard default assumptions for fish ingestion of 25 grams/day for an adult and adolescent. EPA modified the ingestion rate for young children based on bodyweight. Exposure duration was based on standard default assumptions for residents; 6 years for a young child, 24 years for an adult, and 8 years for an adolescent fisher. For the Delaware River and Newton Creek, it was assumed that 100% of the portion offish consumed may be contaminated. For Martin's Lake, it was assumed that 50% of the portion of j5sh consumed may be contaminated. This assumption was based on the size of Martin's Lake (approximately one-third of an acre in size and 18 inches deep) and its inability to provide adequate fish population to support a consumption rate of 25 grams/day.

Toxicity Assessment: Toxicity assessment determines the types of adverse health effects potentially associated with exposures to contaminants at the Welsbach Site and the relationship between the magnitude of exposure (dose) and severity of adverse effects (response). It involves determining whether exposure to a radionuclide can cause an increase in the incidence of a particular adverse health effect. Regarding exposure to radionuchdes, the carcinogenic potential due to chronic exposure to the radionuclides present at the Welsbach Site is the only health effect of concem. Long-term radiation exposure has been found to increase the risk of developing cancer in humans. The baseline human health risk assessment used the current consensus toxicity values for radionuchdes from the Radionuchde Health Effects Assessment Summary Tables (April 2001). Table 3 presents the radionuclide-specific toxicity data for the pathways of exposure evaluated in the baseline assessment {i.e., ingestion of sediment, ingestion offish, and extemal radiation).

Risk Characterization: Risk characterization is the final step in the Human Health Risk Assessment process. It combines exposure and toxicity information to provide a quantitative assessment of site risks. Exposures are evaluated based on the potential risk for developing cancer. EPA expresses the likelihood of an individual developing cancer as a probabihty. For example, a 10-4 cancer risk represents a "one in 10,000 excess cancer risk," or an increased risk of an individual developing cancer of one in 10,000 as a result of exposure to site contaminants under the conditions used in the Exposure Assessment. Under the federal Superfund program, EPA's goal of protection is an excess cancer risk of 10-6 or less for the RME individual. Acceptable exposures, as outlined in the NCP, are an individual with excess cancer risk at or below the range of 10-4 to 10-6 (corresponding to one in 10,000 to one in 1,000,000 excess cancer risk). Tables 4.1 to 4.4, summarize the potential for carcinogenic health effects associated with possible exposure to ROPCs in sediment and animal tissue in the water bodies. These tables provide a summary of the potential cancer risks associated with exposure to the medium of concem (i.e., sediment and fish) or "gross" cancer risks and the potential cancer risks from background exposure. To estimate "net" risks, or risks without contribution from background, EPA subfracts the background risks from the gross cancer risks.

500015 10 The results of EPA's risk characterization include:

• Potential for adverse health effects for recreationalists exposed to radionuclides in sediment (via extemal radiation and ingestion) were within EPA's acceptable risk range.

• Potential for adverse health effects for adolescent and young child fishers exposed to radionuchdes in animal tissue (via consumption offish) from the Delaware River, Newton Creek, and Martin's Lake were within EPA's risk range.

• Potential for adverse health effects for an adult fisher exposed to radionuclides in animal tissue (via consumption offish) from the Delaware River and Newton Creek were within EPA's risk range.

• A calculated cancer risk of 3 x 10"^ (i. e., 3 in 10,000) for an adult fisher exposed to radionuclides in animal tissue (via ingestion offish) from Martin's Lake. This risk is within the upper bound of EPA's acceptable risk range. However, EPA concluded that a more realistic cancer risk would be less than 90 % of the calculated cancer risk since the main contributors to the risk estimate {i.e., radium and lead) are bone seekers and are not expected to be present in edible fish tissue.

Screening Level Ecological Risk Assessment

Similar to the human health risk assessment, EPA used the following four-step process for assessing site-related ecological risks for a reasonable maximum exposure scenario:

1) Problem Formulation, a quahtative evaluation of contaminant release, migration, and fate; identification of contaminants of potential concem, receptors, exposure pathways, and known ecological effects of the contaminants; and selection of endpoints for fiirther study;

2) Exposure Assessment, a quantitative evaluation of contaminant release, migration, and fate; characterization of exposure pathways and receptors; and measurement or estimation of exposure point concenfrations;

3) Ecological Effects Assessment, literature reviews, field studies, and toxicity tests, hnking contaminant concenfrations to effects on ecological receptors; and

4) Risk Characterization, measurement or estimation of both current and fiiture adverse effects.

Problem Formulation: As described earlier, radionuclides in the uranium and thorium series are the primary contaminants of potential concem. Table 5 presents a summary of the radionuclides of potential concem and sediment data evaluated in the screening-level ecological risk assessment. '

Exposure Assessment: The screening level ecological risk assessment focused on aquatic organisms, including fish, and did not evaluate the potential risk to higher-level organisms such as waterfowl, muskrats, and beavers. EPA considered fish as the potential receptors of concem

11 500016 for radionuclides because they have more potential for exposure to radionuclides in sediments than do semi-aquatic bfrds and mammals. They are also more sensitive to radiological damage than bottom-dwelling invertebrates (See Table 6).

Ecological Effects Assessment: There are very few studies on ecological risk from radiological contaminants. Therefore, EPA compared the radionuclide concenfrations found in the sediment samples at the Welsbach Site to multi-media benchmarks developed by the U.S. Department of Energy's (DOE's) Oak Ridge National Laboratory (See Table 5). The adjusted benchmarks assume that the sediment and surface water concenfrations are in equilibrium, and thus consider potential surface water exposure. These benchmarks are identified in DOE's 1998 document titied "Radiological Benchmarks for Screening Contaminants of Potential Concem for Effects on Aquatic Biota at Oak Ridge National Laboratory, Oak Ridge, Tennessee." Radiological levels above the benchmark or guideline values would indicate that sediments and surface water could cause harmfiil impacts to ecological receptors.

Risk Characterization: The resuhs of this analysis indicated that the radionuchde concenfrations in sediment and surface water are well below the DOE guideline levels (See Table 5). Furthermore, all of the sediment samples collected had radionuclide concenfrations tiiat were indistinguishable from the levels found in the area. Therefore, EPA has determined that radionuclides do not cause an unacceptable ecological risk at the Welsbach Site.

Discussion of Uncertainties in Risk Assessment

Human Health Risk Assessment

Some uncertainty is inherent in the process of conducting predictive, quantitative human health evaluations. This uncertainty is associated with each component of the process, including environmental sampling and analysis, chemical fate and fransport modeling, human exposure assessment, and the toxicological criteria used to characterize potential health risks. Uncertainty in any of these components could alter the risk estimates.

Environmental Sampling

Uncertainty associated with envfronmental samphng is generally related to the limitations of the sampling in terms of the number and distribution of samples, while uncertainty associated with the sample analysis is generally associated with systematic or random errors (e.g., false positive or negative results). Thus, exposure may overestimate or underestimate risk depending on how well each environmental medium is characterized.

The use of the maximum detected radionuclide concenfrations in the evaluation of Martin's Lake may have resulted in an overestimation of risks. In addition, sampling locations for radiological analysis were not selected randomly; sampling locations for radiological analysis were generally biased towards potential sources of contamination (e.g., contiguous to areas of know contamination, storm water outfalls, etc.). Therefore, some of the maximum detected ROPC concenfrations used in the evaluation may be biased high and potentially overestimate risks.

500017 12 Fate and Transport Modeling

EPA derived the concenfrations of radionuclides in animal tissue (i.e., fish) by converting sediment concenfrations to pore water concenfrations using fate and fransport modeling. EPA then calculated fish tissue concenfrations using bioaccumulation factors (BAFs). These models were developed for chemicals; however, EPA used these models for the radionuclides in this evaluation because there are no fate and fransport and BAF models for radionuclides. Furthermore, because these models are intended for non-radionuclide chemicals, they do not account for the physical and chemical characteristics of the radionuchdes (i.e., radium, which is a bone seeker, and accounts for approximately 50% of the total risk). Therefore, the calculated risks from radionuchdes in fish may be overestimated.

Human Exposure Modeling

Uncertainties in the exposure assessment are related to estimates of how often an individual would actually come in contact with the contaminants of potential concem, the period of time over which such exposure would occur, and in the models used to estimate the concenfrations of the containinants of potential concem at the point of exposure.

In addition to the calculation of exposure point concenfrations, several site-specific assumptions regarding fiiture land use scenarios, intake parameters, and exposure pathways are a part of the exposure assessment stage of a baseline risk assessment. EPA based these assumptions on site- specific conditions to the greatest degree possible. In the absence of site-specific data, EPA used default parameter values found in EPA risk assessment guidance documents. However, there remains some uncertainty in the prediction of future use scenarios and their associated intake parameters and exposure pathways.

Toxicological Criteria

Uncertainties in toxicological data occur in exfrapolating from high to low doses of exposure, as well as from the difficulties in assessing the toxicity of a mixture of radiological contaminants. EPA addresses these uncertainties by making health protective assumptions concerning risk and exposure parameters throughout the assessment. As a result, the baseline human health risk assessment provides upper-bound estimates of the risks to populations near the Site, and it is highly unlikely to imderestimate actual risks related to the site.

Human epidemiological data on carcinogenesis from exposure to ionizing radiation are more extensive than that for most chemical . However, these data are based primarily upon studies of populations exposed to radiation doses and dose rates that are higher than the levels of concem in this risk assessment. Use of these data to predict excess cancer risk from low-level radiation exposure requires exfrapolation based on estimated dose-response assumptions. However, the risk estimators used in this assessment are generally accepted by the scientific community as representing reasonable projections of the cancer risks associated with exposure to the various radionuclides.

13 500018 Screening-Level Ecological Risk Assessment

Some uncertainty is inherent in the process of conducting a screening-level ecological risk assessment. Envfronmental sampling and analysis and exposure calculations are prone to uncertainty, as are the available toxicity data used to characterize risks.

Environmental Sampling

Uncertainty associated with envfronmental sampling is generally related to the limitations of the sampling program in terms of the number and distribution of samples, while uncertainty associated with the analysis of the samples is generally related to systematic or random eirors.

Exposure Assessment

Another point of uncertainty hes in the assumption that each of the wildhfe receptor species feeds only upon food items found in the study areas. For species with very small home ranges (e.g., organisms that live in the sediment), this assumption is likely to be close to actuality. However, other receptors (e.g., fish) may consume food sources other than those considered in the assessment, the exclusion of which could either over- or underestimate the potential risk. It is possible that receptors may not feed entirely within the sampling areas, but may look for food in other areas as well.

Screening Benchmarks

The multimedia sediment benchmarks used in the screening-level ecological risk assessment do not include the extemal dose from water, which is considered a minor source of error relative to the extemal radiation from the sediment. Also, the multimedia sediment benchmarks were calculated using default sediment/water partition coefficients and bioconcenfration factors. There is uncertainty associated with these factors.

OU3 Risk Characterization Summary

The primary containinants of potential concem for the Welsbach Site are radionuchdes in the thorium and uranium decay chains. The results of EPA testing did not indicate elevated radionuclide concenfrations in sediments in the Welsbach Site study area. Although the levels of some chemical contaminants of potential concem exceeded the ecological guidelines and human health risk levels in the surface water, sediment, and wetland study area, these chemical contaminants are not related to operations associated with Welsbach and GGM.

EPA's baseline human health risk assessment found that effects from exposures to the radionuclide concenfrations in the sediments are within the upper bounds of EPA's acceptable risk range. In addition, the screening level ecological risk assessment results indicate that the radionuclide concenfrations in the sediments are below EPA's level of concem. Therefore, no remedial action is necessary because EPA has determined that no unacceptable risk to human health and the environment exists from radionuclides in the surface water, sediment, and wetland areas in the Welsbach Site study area.

500019 14 STATE ACCEPTANCE

The State of New Jersey concurs with the selected no action remedy.

DOCUMENTATION OF SIGNIFICANT CHANGES

EPA released the Proposed Plan for 0U3 of the Welsbach Site for pubhc comment on May 24, 2005. The Proposed Plan identified No Action as the preferred remedy for the surface water, sediment, and wetland areas at the Welsbach Site. EPA reviewed all comments received during the public comment period, and determined that no significant changes to the no action remedy, as originally identified in the Proposed Plan, were necessary or appropriate.

Welsbach and General Gas Mantle Contamination Superfund Site

INTRODUCTION

This Responsiveness Summary provides a summary of the pubUc's conmients and concems regarding the Proposed Plan for Operable Unit 3 (0U3) of the Welsbach and General Gas Mantle Contamination site (Welsbach Site), and EPA's responses to those comments. 0U3 includes the smface water, sediments, and wetland areas in the Welsbach Site study area. At the time of the public comment period, EPA proposed "no action" for 0U3. All comments summarized in this docimient have been considered in EPA's final decision for selecting a no action remedy for the surface water, sediment, and wetland areas in the Welsbach Site study area.

This Responsiveness Summary is divided into the following sections:

I. BACKGROUND ON COMMUNITY INVOLVEMENT AND CONCERNS: This section provides the history of community involvement and interest regarding the Welsbach and General Gas Mantle Contamination Site.

n. COMPREHENSIVE SUMMARY OF MAJOR QUESTIONS, COMMENTS, CONCERNS, AND RESPONSES: This section contains summaries of oral comments received by EPA at the public meeting, EPA's responses to these comments, as well as . responses to written comments received diuing and after the public comment period.

in. ATTACHMENTS: The last section of this Responsiveness Summary provides attachments which document public participation in the remedy-selection process for this Site. The attachments are as follows:

Attachment A: the Proposed Plan that was distributed to the public for review and comment;

Attachment B: the public notices that appeared in the Courier-Post;

Attachment C: the transcripts of the public meetings; and

Attachment D: the written comments received by EPA diuing and after the pubhc comment period.

500039 I. BACKGROUND ON COMMUNITY INVOLVEMENT AND CONCERNS

In January 1999, EPA made available for public comment the Proposed Plan and supporting documentation for Operable Unit One (OUl). EPA conducted public meetings in both Gloucester City and Camden to inform local officials and interested citizens about the Superfimd process, to review proposed remedial activities at the Site and receive comments on the Proposed Plan, and to respond to questions from area residents and other mterested parties. After evaluating comments received during the public comment period, EPA selected a remedy for OUl, which included demohtion of the General Gas Mantle Building and the excavation and off- site disposal of the radiologically contaminated soils at the Welsbach Site. During the OUl public comment period, community interest was moderate in Gloucester City and low in Camden.

On May 24,2005, EPA released the Proposed Plan and supporting documentation for the no action remedy for the surface water, sediment, and wetland areas in the Welsbach Site study area (0U3) to the public for comment. EPA made these documents available to the pubhc in the administrative record repositories maintained at the EPA Region n office (290 Broadway, New York, New York), the City of Camden Main Library (418 Federal Street, Camden, New Jersey 08103); the Hynes Center (1855 South 4th Street, Camden, New Jersey 80104); and the Gloucester City Public Library (Monmouth and Hudson Streets, Gloucester City, New Jersey 08030). Notices of availability for the documents in the administrative record were published in the Courier-Post on May 24,2005, and July 25,2005. The initial pubhc comment period was held from May 24 through June 23,2005. However, at the request of the NJDEP, EPA extended the pubhc comment period to August 2,2005. EPA held two public meetings to present the preferred no action remedy for OU3. The first meeting was held on June 8,2005, at the Welsbach Field Office, and the second meeting was held on July 26, 2005, at the Camden County Municipal Utilities Authority (CCMUA).

II. COMPREHENSIVE SUMMARY OF MAJOR OUESTIONS. COMMENTS, CONCERNS. AND RESPONSES

PART 1: Verbal Comments

This section summarizes conunents received from the pubhc during the pubhc comment period, and EPA's responses. EPA held public meetings on June 8,2005, at 7:00 p.m. at the Welsbach Field Office, 130 N. Broadway, Gloucester City, New Jersey, and on July 26,2005, at 7:00 p.m. at CCMUA's auditorium, 1645 Ferry Avenue, Camden, New Jersey.

June 8. 2005 Public Meeting

Comments and questions raised by the public following EPA's presentation are categorized by relevant topics and presented as follows:

500040 • Surface Water, Sediment, and Wetland Investigation • Human Health and Ecological Risk • Remedial Action • General Community Concems

Surface Water, Sediment, and Wetland Investigation

Question 1: What were the radionuchde concentrations in the sediment and background samples?

EPA Response: The radionuclide concenfrations found in the background sediments were less than one picoCurie per gram (pCi/g). A comparison of the concenfrations detected in the samples to the average concenfrations found in the background samples indicated that the results were indistinguishable. In other words, the levels found in the sediments adjacent to the site were the same as the concenfrations found in the background samples. These levels are also similar to statewide radionuclide averages for radium and thorium.

Question 2: How were the background sampling areas selected?

EPA Response: The background samples were collected from locations upsfream of the known areas of contamination, thereby minimizing any potential that these samples could have been contaminated by radionuchdes from the site.

Question 3: What was the basis for selecting the sediment sampling locations? Since thorium does not migrate, were the locations selected because EPA believes there might have been dumping in these areas?

EPA Response: EPA selected sediment sampling locations that were adjacent to either potentially contaminated properties, or known contaminated properties in order to determine if contamination migrated from these areas. These properties included the Swim Club, the Land Preserve on Johnson Boulevard, north and south of Nicholson Road, and the Komatsu Yard. The Komatsu Yard is potentially contaminated property along Broadway, north of the Walt Whitman Bridge. In addition, EPA collected samples from outfalls in the Delaware River and Newton Creek. EPA sampled eight storm water runoff outfalls in the Delaware River and two outfalls in Newton Creek.

Question 4: Was the overflow pipe that entered Newton Creek just south of the Little League field still there, and if so, was it sampled?

EPA Response: The pipe is still present. It is one of the outfall points EPA sampled during the investigation.

500041 Human Health and Ecological Risk

Question 1: Were the risks from chemical contaminants included in the risk assessment and were the non-radiological chemicals associated with the site?

EPA Response: EPA conducted a baseline human health risk assessment for both radionuclides and chemicals found in the sediment samples. As part of non-radiological chemical assessment, EPA looked at ingestion offish which were potentially contaminated from the water bodies adjacent to the site. EPA looked at ingestion rates for young children (0-6 years of age), adolescents (10-18 years of age) and adults (greater than 18 years of age) and calculated risks from ingestion of potentially contaminated fish.

EPA also noted that one of the primary chemicals found in the water bodies was polychlorinated biphenyls (PCBs). PCBs have been found throughout the river system and are the basis for a State of New Jersey fish consumption advisory. However, PCBs are not related to the site. In the United States, PCBs were primarily used from the mid-1930s until 1977 when they were banned by EPA. Both the Welsbach Company and General Gas Mantle Company went out of business in the early 1940s, and there is no evidence that they used PCBs.

Question 2: Was the risk assessment based on state or federal standards?

EPA Response: The assessment followed a risk-based approach that includes federal Superfimd and EPA guidance and pohcies. The federal standards for fish ingestion were not used because federal standards, {i.e.. Food and Dmg Adminisfration), assume that an individual would be ingesting fish obtained from more than one source. The risk assessment assumed that a reasonable maximum exposed individual would be consuming his/her entfre fish diet from the water bodies evaluated in the risk assessment.

Question 3: Is there any risk from Martin's Lake since many generations of people in the town swam in the lake?

EPA Response: EPA's investigations at Martin's Lake identified radiological contamination on a very small area on the land, along the northern shore of the lake. The area is only a few cubic yards in size. There is not enough contamination present that would pose a risk for the activities described. To be at risk, a person would have to be in contact with the soil for a long period of time (i.e. daily for 30 years).

Question 4: What were the benchmark criteria EPA used for the ecological risks?

EPA Response: Benchmarks are values that are protective of ecological receptors, such as benthic organisms (organisms that live in sediment). There are a number of sources for the benchmarks. These sources can be found in the Screening Level Ecological Risk Assessment. These criteria are mainly based on hterature values for specific species identified from scientific research.

500042 Remedial Action

Question 1: Does EPA intend to remove the contaminated soil at Martin's Lake?

EPA Response: Yes, EPA will remove the contaminated soils on the land portions along the shore of Martin's Lake. This cleanup is part of the remedy EPA selected in the 1999 ROD. The purpose of this proposed plan for 0U3 was to discuss whether or not the contamination on the land made its way into the water bodies that are adjacent to the site. EPA found no contamination in the sediments of these water bodies.

General Community Concerns

Question 1: How did EPA discover the Welsbach Site, and how does EPA know where the radiological contamination is located?

EPA Response: EPA and NJDEP have conducted several extensive studies throughout Gloucester City and Camden. In the early 1980s, NJDEP used an aerial radiological flyover and identified five areas of radiological contamination. Since 1996, EPA has reviewed numerous historic maps and conducted detailed radiological investigations to identify properties where dumping may have occurred. When EPA compared the aerial radiological flyover with the historic maps, EPA found five additional contanoinated properties.

Question 2: With respect to the aerial radiological flyover, how accurate is it, and does EPA plan to conduct another survey?

EPA Response: An aerial survey will not identify small-scale radiological contamination, such as a small area of contamination in someone's backyard. For this reason, EPA is conducting a ground-based yard-by-yard survey. In the early 1990s, the State of New Jersey investigated approximately 1,100 properties within the original five study areas. EPA later identified a sixth area in Gloucester City, the Popcom Factory parcel, where a middle school is proposed to be built. Within the six study areas, there are oVer 1,200 properties that the EPA and/or the State of New Jersey investigated with more accurate equipment than what is used dming an aerial survey. Once these investigations are complete, EPA will clean up the contaminated properties.

EPA has not conducted another aerial survey since a new survey would only show the same areas that have already been identified. An aerial survey will only show large sites with large amounts of radiological material because the "shine" from highly contaminated areas will block out any nearby low level contaminated areas. Once the contamination from the large areas is removed, there is a chance that a new aerial survey could show some smaller arezis. At present, EPA does not have any plans to conduct another aerial survey, it is something that may be considered in the future after all the work is completed.

Question 3: Have conditions changed since the aerial radiological survey {e.g., moving of fill)?

500043 EPA Response: There are historic aerial photographs for the site from 1930 through 2000. EPA compared and reviewed these aerial photographs and found no new areas of dumping.

Question 4: When did the dumping in the Martin's Lake area start and when did it end?

EPA Response: Based on historical aerial photos, dumping activities were identified on the triangle property between Klemm and Highland Avenues as early as the 1930s. It appears these activities continued through the 1940s, 1950s, and into the 1960s. It is likely there were different generations of waste from multiple sources being deposited on these properties. One source for the contamination at Martin's Lake could be from the nearby contamination at Klemm and Highland Avenues. A portion of the radiologically contaminated soil at Klemm and Highland properties was originally dumped by Welsbach at the Gloucester City Swim Club. EPA was told by the owner of one of the Klemm and Highland properties that when the pools were dug at the Swim Club some of the excess soils were placed on the Klemm property.

Welsbach went out of business in 1940. In the late 1950s when the Walt Whitman Bridge was built, a number of Welsbach buildings were knocked down. EPA believes that some of the building material may have been deposited on the Jogging Track area that was formerly part of Newton Creek. It is possible that some of this material may also have been placed in the Martin's Lake area.

Question 5: How could contaminants from the site get into Martin's Lake?

EPA Response: During the remedial investigation in the late 1990s, EPA identified an area on the land portion of Martin's Lake that had elevated levels of radionuclides. The area is roughly three feet square and the contamination is relatively shallow (approximately 1.5 to 2 feet in depth). During the surface water investigation, EPA conducted additional sampling at Martin's Lake to determine if the contamination found on the land portion extended into the lake. EPA found no contamination in these sediments.

Question 6: How mobile are the radionuclides in sediment and water, how long is thefr half Ufe, and will the radionuclides underwater radiate energy in all dfrections?

EPA Response: Thorium is a heavy metal that does not migrate far in soil. It also has a low partitioning coefficient, which means that if it gets into water it doesn't dissolve into the water. Thorium is a radioactive element, and as part of its process it breaks down into daughter products. Those daughter products release energy as photons, alpha and beta particles, and gamma rays, as part of the decay process. The half life of thorium is 14 bilhon years.

Question 7: Is coal tar radioactive?

EPA Response: No, coal tar is not radioactive.

Question 8: Was radiological material dumped in the old racetrack area of Gloucester City that was filled in during the late 1890s.

^ 500044 EPA Response: During the cleanup of the Popcom Factory, some historic maps were found that identified a tributary of the Delaware River called the Indian Run. Indian Run ran right along the old racefrack area, through the Popcom Factory parcel, and then north. This tributary was filled in from the 1890s through the 1900s. Radiological contamination has been found in Indian Run at several locations including at the Popcom Factory and across the sfreet off 7th Sfreet between Jersey and Charles Sfreets.

July 26.2005 Pubhc Meeting

At this public meeting, EPA presented the proposed no action remedy for OU3 at the Welsbach Site together with the EPA's proposed remedy for the Martin Aaron Superfimd site. A portion of the Welsbach Site is adjacent to the Martin Aaron site. Conunents and questions raised by the pubhc following EPA's presentation regarding the Welsbach Site are presented below.

Question 1: A question was asked, in reference to the Martin Aaron Superftmd Site - were groundwater samples analyzed for radionuclides, and if so what were the results?

EPA Response: EPA collected groundwater samples from monitoring wells located on the Martin Aaron property for radionuclide analysis during the remedial investigation for the Welsbach Site. ITie radionuclide concenfrations in the groundwater samples collected from monitoring wells located on the Martin Aaron property were below drinking water standards. Radionuclide contamination in the groundwater was only foimd in samples collected immediately adjacent to the Welsbach Facility and several dumping areas in Gloucester City and the General Gas Mantle building in Camden.

Question 2: Does EPA use a 48-hour tum-around-time for^oundwater gross alpha analysis?

EPA Response: EPA followed the standard laboratory procedures that were in place during the time of the groundwater sampling.

Question 3: What is the proposed remedy for the Welsbach Site?

EPA Response: EPA is proposing no further action for the surface water, sediment, and wetland portion of the Welsbach Site (0U3):

Question 4: Is further reihediation planned at the General Gas Mantle property beyond the demolition of the building and covering of the property with gravel?

EPA Response: EPA will be removing all the radiologically contaminated soil from the property once funding becomes available. EPA's first priority is to remediate residential areas.

Question 5: Could EPA confirm that radiological samples were collected from wetland areas and used to evaluate human health and ecological risks.

500045 EPA Response: EPA collected sediment samples from three water bodies (the Delaware River, Newton Creek, and Martin's Lake) contiguous to the Welsbach Site for radiological analysis. The data were used to evaluate potential human health and ecological risks.

Question 6: What were the background radionuchde concentrations and were the sediment samples above the background concenfrations?

EPA Response: The average radionuclide concentrations for thorium and radium in both the sediment and background samples were less than 1.2 pCi/g. These concenfrations are consistent with statewide averages for background radionuchde concenfrations. Radionuclide concenfrations were, on average, equal to levels found in uncontaminated areas in the vicinity of the Welsbach Site (background levels).

Question 7: How were the background radionuchde concenfrations used in the calculation of risks?

EPA Response: EPA used the background radionuchde concenfrations to estimate "background radiation" cancer risks. After determining the "background radiation" risks, EPA subfracted the background risks from the total risk from all sources.

Question 8: Were non-site-related chemicals detected in sediment samples?

EPA Response: At nearly all of the sediment sampling locations, EPA detected non-radiological chemical constituents at levels that exceeded the maximum background concenfrations and sediment screening guidelines. In the area of the Welsbach Site, heavily developed industrial areas are located near the surface water bodies. These industrial areas are potential sources of these non-Welsbach site-related chemicals found in the sediment.

Question 9: Do the background concenfrations of radionuchdes in sediment increase the risk to human health and the envfronment from the non-site-related chemicals?

EPA Response: The risk assessment evaluated the potential for adverse effects to human health and the envfromnent from both radionuclides and non-site-related chemicals. Initially, the potential risks from exposure to radionuclides and non-site-related chemicals were evaluated separately. The risks were then combined since individuals may be exposed to both radionuclides and chemicals. EPA found that the contribution from radionuclides did not increase the risk from exposure to the non-site-related chemicals.

Question 10: Was EPA able to determine the source(s) of the non-site-related chemicals detected in sediment?

EPA Response: In the area of the Welsbach Site, heavily developed industrial areas are located near the surface water bodies. These industrial areas are potential sources of the non-Welsbach site-related chemicals found in the sediment.

500046 EPA also noted that the primary chemical of concem in sediments is PCBs. PCBs have been found throughout the river system and are the basis for a State of New Jersey fish consumption advisory. However, PCBs are not related to the site. In the United States, PCBs were primarily used from the mid-1930s until 1977 when they were banned by EPA. Both the Welsbach Company and General Gas Mantle Company went out of business in the early 1940s, and there is no evidence that they used PCBs.

Question 11: Has EPA attempted to locate or identify any former workers who may have worked in the General Gas Mantle building or any residents who may have lived in the vicinity of the facihty to conduct an assessment of thefr health?

EPA Response: The Agency for Toxic Substances and Disease Registry (ATSDR) working with the New Jersey Department of Health and Senior Services performed a health assessment for Gloucester City and Camden as part of the Welsbach Site. They found that there was an increased risk of cancer in the two areas but that this increase was primarily attributed to smoking. ATSDR did not look at historic exposures in the cities.

PART 2: Written Comments

Comments and concerns that were not addressed at the public meeting were accepted in writing during the public comment period. Copies of these comments are included in Appendix D of this Responsiveness Summary. A summary of each written comment received is included below along with EPA's response.

Question 1: An email was received from a professor at Rutgers University, Camden. He indicated that it would be helpful for the public understanding if EPA conducted a follow-up assessment of contamination levels, after remediation is completed. He would like this assessment to show the initial levels as compared to the post-remediation levels of radionuchdes, in order for the public to discern whether or not the EPA did what the ROD requfres.

EPA Response: After the cleanup at each construction unit, EPA conducts a Final Status Survey, consisting of the collection of a statistically significant number of soil samples. The results of these samples are used to determine whether EPA has met the cleanup levels specified in the ROD. If not, additional excavation and sampling is conducted. In addition, post- remediation measurements, including a surface exposure rate scan, and where applicable, radon/thoron levels, are also collected for additional verification. At the conclusion of each remedial action, EPA prepares a Remedial Action Report which summarizes the cleanup activities at the site, and documents that the cleanup has met the ROD requfrements.

Question 2: An email was received from two residents of Haddon Township, New Jersey, a city approximately 10 miles from the Welsbach Site. They have recently noticed a number of crippled, disfigured and otherwise handicapped Mallard ducks in thefr area. They asked if the study that was performed to determine the level, extent and impact of the contamination included study of effects on wildlife, and whether or not the abnormalities seen in the Mallards are in any way linked to the contamination.

500047 EPA Response: The main purpose of EPA's study was to see whether the radiological contamination on the site^properties had contaminated the surface water, sediment, and wetland areas adjacent to these site properties. As part of our investigation, EPA collected both radiological and chemical samples in the Delaware River, Newton Creek, and a small lake in Gloucester City called Martin's Lake.

With the data from these samples, EPA conducted a screening-level ecological and human risk assessment to assess the risk posed by the radionuclides and chemicals we found in the samples. The screening-level ecological risk assessment focused on aquatic biota (fish) and did not evaluate the potential risk to higher-level organisms {e.g.. Mallard duck and other semi-aquatic animals). Fish were considered to be the potential receptors of concem for radionuchdes, since they have more potential for exposure from sediments tiian semi-aquatic birds or manmials, and they are more sensitive to radiological exposure than benthic invertebrates (animals that live in the sediments). For the chemicals of concern, benthic invertebrates were considered the receptors of potential concem, since these organisms have the greatest potential for exposure of the aquatic and semi-aquatic organisms that may use the water bodies.

Part HI - Written Comments Received After Public Comment Period On September 14,2005, EPA received the following comments. These conraients were received well after the public comment period closed. However, as a courtesy, EPA has decided to respond to these conunents in this Responsiveness Suimnary.

Comment 1: During the pubhc meeting it was revealed that radioactivity had been discovered at the Martin Aaron site, which is roughly Yi mile north of the General Gas Mantle site^ and within Study Area 1 of the Welsbach Superfund site. No acknowledgement of this fact was provided in the public handouts for either site. A complete set of the radiological data for the Martin Aaron site should be included in the Martin Aaron RA Selection report. Additionally, the impact of this radioactive material on the proposed disposal of Martin Aaron soils must be evaluated. The likely origin of the radioactivity at the General Gas Mantle site indicates this assessment should be part of the Welsbach site activities.

Response: To date, EPA has not identified any radiological contamination on the Martin Aaron Site proper. EPA found elevated radionuclide concenfrations on the Leitka and Whitman Park properties across the sfreet from the Martin Aaron Site. The Leitka property is identified in the Martin Aaron site Proposed Plan as the South Jersey Port Corporation property. As part of the Martin Aaron Site remedial investigation, EPA investigated the Leitka property and determined that it was not part of the Martin Aaron Superfund Site. EPA will address the radiological contamination on the Leitka and Whitman Park properties as part of the Welsbach Site remedial action. If radiological contamination is found on the Martin Aaron site during response actions at that site, EPA will dispose of the radiological waste in accordance with the cleanup standard identified in the Welsbach 1999 Record of Decision.

500048 Comment 2: The EPA expended fimds collecting and analyzing sediment and surface water samples for chemical contaminants then expended fimds to conduct human health and ecological risk assessments for those chemicals. Why these funds were expended when there was no intent to use the data should be explained. In addition, this data must be fransmitted to the NJDEP.

Response: While it is tme that site-related contaminants are limited to radionuclides, a trae ecological assessment cannot be accomphshed without a comprehensive understanding of all potential impacts. Therefore, it was essential that non^radiological compounds also be included in the assessment. This is in accordance with EPA guidance. All of the data generated from the sampling and assessment has been provided to NJDEP.

Comment 3: EPA states that the chemicals found in thefr samples were not in use when Welsbach and General Gas Mantle operated, apparently as its justification for not corisidering thefr chemical data when evaluating cleanup options. Both of these facilities had to have used coal and would, therefore, have produced polyaromatic hydrocarbon compounds (PAHs) in thefr coal ash. PCBs, according to the USEPA web site, were manufactured from 1929 to 1977, and thefr presence/use at these sites cannot be excluded. Widespread use of DDT as a pesticide commenced in 1939 (although the compound was created cfrca 1874). The blanket exclusion of Welsbach as a potential source of chemical contaminants is not justified. The potential contribution of the Welsbach site to the contaminated sediments requfres an evaluation.

Response: EPA disagrees that further evaluation of the chemical contamination in the sediments is required under the Superfimd program. The primary contaminants of concem at the Welsbach Site are thorium and radium. If the chemical contamination were related to the Welsbach Site, one would expect that radionuclides would be present in the areas where chemical contaminants were found. The thorium and radium concenfrations were on average, equal to levels found in the background samples in the surface water, sediment, and wetland areas in the Welsbach Site study area.

Coal was extensively used throughout the Camden and Philadelphia industrial region during the 1800s and early 1900s, and elevated levels of PAHs are found in the soils throughout the region. EPA qualitatively evaluated PAHs in the human health risk assessment. EPA evaluated multiple pathways and identified ingestion of fish as the primary pathway of exposure. As described in the Human Health Risk Assessment Addendum, PAHs do not readily bioaccumulate in fish, and therefore, no further quantitative evaluations were necessary.

PCBs were the only non-radiological chemicals of concem identified in the 0U3 Welsbach Site study area that posed an unacceptable risk to human health. As described in the Agency for Toxic Substances and Disease Registry Toxicological Profile for PCBs,

11

500049 "... Prior to 1974, PCBs were used both for nominally closed apphcations (e.g., capacitor and fransformers, and heat fransfer and hydraulic fluids) and in open-end applications (e.g., retardants, inks, adhesives, microencapsulation of dyes for carbonless duplicating paper, paints, pesticide extenders, plasticizers, polyolefin catalyst carriers, slide-mounting mediums for microscopes, surface coatings, wfre insulators, and metal coatfrigs) (Durfee 1976; EPA 1976a, 1988c; L\RC 1978; Orris et al. 1986; Safe 1984; Welsh 1995)."

These activities were not conducted at the Welsbach or General Gas Mantle gas mantle manufacturing facihties. Furthermore, PCBs were not in wide use when these facihties operated. EPA determined, therefore, that PCBs are not related to the gas mantle manufacturing activities at the Welsbach Site. Therefore, no additional evaluation of PCBs in the surface water, sediment, and wetland areas in the Welsbach Site study area is necessary under the Superfund program. EPA provided the PCB data to NJDEP. NJDEP is currently sfridying the PCBs ui the Delaware River basis under its regulatory authorities.

Although DDT was selected as a chemical of potential concem, EPA determined that it did not pose an unacceptable risk to human health at tiie Welsbach Site. Furthermore, DDT was not in wide use during the time Welsbach and General Gas Mantle operated, and was not identified in soils at the Welsbach and General Gas Mantle facilities.

REMEDIAL ACTIONS IMPLEMENTED TO DATE SITE CHARACTERISTICS

Thus far, EPA's cleanup of the Welsbach Site has As noted earlier, EPA stated in the 1999 ROD that involved four phases. it would evaluate the potential radiological impact to the nearby surface water, sediment, and wetland The first phase involved the demolition of the areas. EPA's first step in this process was to GGM Building in Camden.

500055 WHAT ARE THE POTENTIAL • To provide sufficient data to make either a "CONTAMINANTS OF CONCERN"? "no further action" recommendation or EPA has ideritified several contaminants in the' recommendations for fiirther studies. sediments near the Welsbach Site. These contaminants fall into two categories, those EPA conducted the investigation of surface waters, related to the maiiufacturing process of the sediments and wetlands in Study Areas 1, 2, 3, 5, former Welsbach and General Gas Mantle and 6 of the Welsbach Site. As previously facilities, and those most likely from other discussed, EPA did not include Study Area 4 in industries in the area. this investigation because the soil contamination is in very small and isolated areas. The Welsbach Site-related contaminants of concern are part of the uranium and thorium The investigation included collecting sediment decay chain, specifically radium-226, radium- samples and measuring the water quality in 228, thorium7230, and thorium-232. These Newton Creek (Smdy Area 3), the South Branch radionuclides pose the greatest potential risk to Newton Creek (Study Area 5), Martins Lake human health and the environment at the (Study Area 5), and several storm water outfalls in Welsbach Site; : South Branch Newton Creek and the Delaware River (Study Areas 1, 2, 3, 5 and 6). EPA The Don-Welsbach Site-related contaminants collected 154 sediment samples and 82 water of potential concern foiind in the sediments quality measurements. Both radiological and include arsenic, lead, :benzo(a)pyrene and chemical data were collected. See Figure 1 for an other PAHs, pesticides such as 4,4:'DDE, 4,4'- overview map of the Study Areas. DDT and heptachlor expoxide, and PCBs. EPA also found elevated concentrations of these chemicals in the background samples. EPA collected ten background sediment samples at I locations upstream of the Welsbach Site in Newton In general, the area surrounding the Welsbach Creek and South Branch Newton Creek, as well as Site includes historic and current in North Branch Newton Creek, Little Timber manufacturing facilities that used a variety of Creek and Miller's Lake. chemicals that were not in use or available when Welsbach made gas mantles. This INVESTIGATION RESULTS supports EPA's conclusion that the non- radiological chemicals are not related to the For the radionuclides of potential concem, the WelsbachSite. ^ ^ radionuclide concentrations in the sediments were, on average, equal to levels found in uncontaminated areas in the vicinity of the Welsbach Site (background levels). The average radionuclide concentrations for thorium and potential sources of these non-Welsbach site- radium in both the sediment and background related chemicals found in the sediment. samples were less than 1.2 picoCuries per gram (pCi/g). NJDEP has issued a "do not eat" advisory for fish and shellfish from the Delaware River in the area At all of the sediment sampling locations, EPA of the Welsbach Site. This advisory is based on detected non-radiological chemical constituents in concentrations of mercury, dioxins, and the sediments that exceeded the maximum polychlorinated biphenyls (PCBs) in fish. As part background concentrations and sediment screening of a statewide program, NJDEP periodically guidelines. This information can be found in the collects samples of edible fish and shellfish in Screening Level Ecological Risk Assessment water bodies throughout the state. NJDEP found (March 2002). In the area of the Welsbach Site, elevated levels of mercury, dioxins, and PCBs in heavily developed industrial areas are located near its Delaware River samples. the surface water bodies. These industrial areas are 500056 WHAT IS RISK AND HOW IS rr CALCULATED?

In a Superfund baseline human health risk assessment, EPA analyzes the potential adverse health effects caused by the release of hazardous substances, including radionuclides, from a site. The risk assessment assumes there will be no actions to control or mitigate the releases under current-and future-land uses. The risk assessment evaluates chemicals of concem that are both site related and non-site related. EPA bases its decisions under the Superfimd program on the risk to human health and the environment from site-related contaminants. ,

EPA uses a four-step process in assessing site-related human health risks for reasonable maximum exposure •scenarios. •

Hazard Identification: In this step, the contaminants of concem at the site in varioiis media (i.e., surface water, sediments, and wetlands) associated with the site are identified based on such factors as toxicity, frequency of occurrence, and fate and transport of the contaminants in the environment, concentrations of the contaminants in specific media, mobility, persistence, and bioaccumulation.

Eyq)osure Assessment: In ibis step, ihe different exposure pathways through which people may be exposed to the contaminants identified in the previous step are evaluated. Examples of exposure pathways include incidental ingestion of and dermal contact with contaminated sediment, and ingestion offish. Factors relating to the exposure assessment include, but are not limited to, the concentrations that people might be exposed to and the potential frequency and duration of exposure. Using these factors, a "reasonable maximum exposure" scenario, which portrays the highest level of human exposure that could reasonably be expected to occur, is calculated.

Toxicity Assessment: In this step, the types of adverse health effects associated with chemicaf and radiological exposures, and the relationship between magnitude of exposure (dose) and severity of adverse effects (response) are determined. Potential health effects are chemical and radionuclide specific and may include the risk of developing cancer over a lifetime or other non-cancer health effects.

Risk Characterization: This step summarizes and combines exposure information and toxicity assessments to provide a quantitative or qualitative assessment of site risks. Exposures are evaluated based on the potential risk of developing cancer and the potential for non-cancer health hazards. The likelihood of an individual developing cancer is expressed as a probability. For example, a 10"^ cancer risk means a "one-in-ten-thousand excess cancer risk"; or one additional cancer may be seen in a population of 10,000 people as a result of exposure to site contaminants under the conditions explained in the Exposure Assessment. Current Superfund guidelines for acceptable exposures are an individual lifetime excess cancer risk in the range of 10"* to 10"* (corresponding to a one-in-ten-thousand to one4n-a-million excess cancer risk). For non-cancer health effects, a "hazard index" is calculated. An HI represents the sum of the individual exposure levels compared to their corresponding reference doses. The key concept for a non-cancer HI is that a "threshold level" (measured as an HI of less than 1) exists below which non-cancer health effects are not expected to occur.

The characterization also identifies risks associatedWith site related and non-site related contaminants. The characterization also considers uncertainties in the components of the assessment including the modeling.

SUMMARY OF SITE RISKS In the 1999 RI/FS, EPA assessed the potential risk As part of the risk assessment process, EPA looks to human health from the radiological at the risks posed by a site to both human health contamination in soil at the Welsbach Site.

LONEY: My name is Natalie Loney. 2 I am the Community Involvement Coordinator for the 3 Welsbach Superfund site and with us tonight, as usual, is 4 Rick Robinson, who is the Remedial Project Manager for 5 the site and next to Rick is Marian Olsen. She's the 6 Hiiman Health Risk Assessor. Thank you. 7 Anyway, the purpose of the meeting today is to 8 discuss the proposed plan for 0U3, which is the surface 9 water sediment and wetlands portion of the site. 10 The way these public meetings run, we do our 11 presentation, at the end of which there is a 12 question-and-answeir period. The questions will be 13 primarily regarding the proposed plan that we presented. 14 I know that there may be other questions regarding other 15 portions of the site. I'm just asking that once we 16 complete that portion of it for the administrative record 17 then we can move on to discuss those other questions, 18 okay. 19 We are going to start off, you see, 20 with the introduction followed by background of 21 the site to bring you up to speed on the history 22 of the site. We'll then go into detail about the 23 surface water sediment and wetland study followed 24 by presentation of some of the sampling results. 25 Marian will then talk about the risk assessment.

# 14 or step in the history of a Superfund site is 15 discovery. That can happen. The state can 16 recommend a site for Superfund. We can even -- 17 sites can even be recommended by citizens. And 18 with this site the state spoke to EPA about the 19 Welsbach site and it was -- we continued with an 20 assessment where we looked at the basic site 21 evaluation, we looked at some of the contaminants 22 and a little bit of the history of the site and 23 that information was used in something we call the 24 Hazard Ranking System.

25 Each one of those criteria are given L Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500068 Page 4 1 a score and depending on the score that the site 2 is given it can qualify for the Superfund site 3 list, which is the NPL listing. 4 This site did score high enough 5 within the Hazardous Ranking System and it was 6 recommended for and placed on the Superfund site 7 list. 8 Being placed on that site -- on that 9 list means your site is now eligible for funding 10 under the Federal Superfund Program and Superfund 11 dollars can be used to address the contamination 12 at the site. So now that we've completed the site 13 assessment phase, we have moved into the remedial 14 phase. The site was placed on the NPL and now we 15 conducted a more intensive assessment of the site, 16 a little bit more involved investigation. 17 And what happened during the course 18 of that investigation, which Rick will be going 19 into detail about, is that the results of that 20 investigation, we're proposing that no-further 21 action is required at the site, at this portion of 22 the site, based on those results.

23 If the — in some of the other 24 portions of the site that we have done work in, 25 the soil portion of the site, we did actually go

ROBINSON: Thanks, Natalie. 18 I was just going to give you a brief 19 overview, a little bit of the history and then go 20 into a little bit on the study. 21 The Welsbach site was originally 22 identified -- originally started basically back in 23 1885 when an Austrian gentleman named Dr. Carl Van 24 Welsbach invented the process of using thorium in 25 the manufacture of gas mantles, and for those of

» 2 little picture of the mantles from the Welsbach 3 , and what they did is they used thorium, 4 which is a radioactive element and they dipped it, 5 the mantle fabric, in this thorium and it caused 6 the mantle to glow brightly when lit.

7 And in the turn of the 20th century 8 it was competing with the electric light as 9 a source of illumination. 10 In the 1890's the Welsbach Company 11 started up here in Gloucester City, and their main 12 peak -- point of manufacturing of the mantles was 13 around World War I. At the time they had employed 14 over 2600 employees here in Gloucester City and 15 they could make up to 250 mantles per day, and in 16 the early '40s they went out of business. 17 In Camden, there's a much smaller gas 18 mantle manufacturing company and that's called 19 General Gas Mantle. They were in operations from 20 1912 to 1941 and Gas Mantle was a much smaller 21 competitor to Welsbach, and we have little 22 information other than that they made gas mantles 23 and they used and resold radi\am and thorium.

24 The Welsbach site, as Natalie said, 25 was identified as part of the investigation

Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500071 Page 7 1 process. 2: In 1980, EPA came across doing a 3 record search of the U.S. radium site in Orange, 4 New Jersey, and there was some literature 5 regarding Welsbach, and as a result EPA then went 6 around and did a helicopter radiological flyover 7 of the Camden and Gloucester City area in 1981. 8 That spawned the New Jersey DEP to come out in the 9 early '90s and investigate over 1100 properties in 10 the Camden and Gloucester City area. 11 As part of the state action, they did 12 a number of interim actions to address immediate 13 health concerns and those actions were basically 14 putting in some steel sheathing, concrete 15 sheathing to shield the radiation and also putting 16 some Radon mitigation systems in some homes. 17 They also purchased two properties 18 and relocated the residents and the business. 19 The site -- we have two study areas, ' 20 two operable units right now out of a total of 21 four that -- where we have a remedy on and the 22 others we are proposing a remedy. 23 Operable unit 1 is the two former gas 24 mantle manufacturing facilities.

We have the 5 gas mantle manufacturing facility up in Camden and 6 then in Gloucester City we have a number of other 7 satellite areas where the tailings from the 8 Welsbach operation were disposed of. We have the 9 Gloucester Swim Club area. We have what we call 10 the Popcorn Factory where they want to build a new 11 middle school. We have property over off of 12 Temple Avenue and over in the jogging track area 13 of Gloucester City. Then also we have identified 14 a few properties in the Fairview section of 15 Camden. 16 And the soils portion of the site is 17 operable unit one and that mainly consists of 18 residential properties, commercial properties and 19 some municipal park land.

20 Operable unit three, which is the 21 purpose of today's presentation, is the water 22 bodies adjacent to those contaminated areas, the 23 Delaware River, Newton Creek and Martin's Lake.

24 The site was listed on the National 25 Priorities list or Superfund list in 1996 and in

5 July 1999. 6 The remedy included demolition of the 7 former gas mantle building in Camden, excavation 8 of the radiological contaminated soils at the 9 properties at the Welsbach site and disposal of 10 material at a licensed offsite disposal facility. 11 The ROD also mentioned that the EPA 12 would address the potential site impacts to the 13 surface water sediment and wetland areas in a 14 future study. 15 That study -- that investigation 16 started in April 2001. We completed a screening 17 level ecological risk assessment in March 2002 and 18 in January 2005 we completed a human health risk 19 assessment for the surface water sediment and 20 wetlands. 21 The purpose of this investigation was 22 to determine if the radionuclides from the site 23 contaminated the adjacent surface water, sediment 24 and wetland areas. 25 EPA — and also to evaluate the

8 the south branch of Newton Creek, although we have 9 the jogging track in this area and Temple Avenue 10 right in through there. 11 As part of the surface water sediment 12 and wetland investigation with radiological 13 contamination, what we do is we have to first 14 conduct a background radiological survey to 15 investigate what the background radiation levels 16 were in the area, and we collected data from five 17 different areas and those are shown on the figure 18 over here. 19 We have the north branch of Newton 20 Creek, the main branch of Newton, over on the 21 south branch of the Newton Creek, Miller's Lake 22 and Little Timber Creek.

5 The sediment sampling results, all 6 the sediment samples for radiological contaminants 7 were within the range of natural background. 8 The chemicals detected in the site -- 9 in the sediment — were not related to the 10 Welsbach site.

11 The sampling data was used for both 12 h\aman health and the screening level ecological 13 risk assessment and these investigation reports 14 are available at the local repositories.

24 explain the risk assessment process that is used

25 at all Superfund sites.

Page 12 1 What risk assessment does is it 2 provides a framework for us to evaluate potential 3 exposures to contaminants and also to evaluate 4 whether remedial action is appropriate at a site. 5 The risk assessment includes two main 6 components. The first is exposure. How is 7 someone coming in contact with the material, 8 whether it's wading;into the river or swimming. 9 Those are the types of things that would be looked 10 at. 11 We also look at the toxicity of 12 individual chemicals that are found. 13 At this site we also did a separate

» 14 radiological assessment and Nidal is here who 15 basically is the radiation risk assessor for this 16 site. 17 The risk assessment looks at risks in 18 the absence of any institutional controls. For 19 example, at the Delaware River at the current time 20 there are fish, consumption advisories in place 21 which recommend that people do not eat fish 22 because of contamination there, so in our 23 assessment we did not evaluate that., If nothing 24 was happening -- if there were no institutional 25 controls such as fish advisories, what would the

And this is a person whose activity 5 patterns bring them into contact with the river, 6 for example, more frequently than an average 7 person who may be there far less, so we're being 8 protective in making our assvimptions about the 9 exposures. 10 As part of the h\aman health risk 11 assessment, we look at various individuals who may 12 be exposed, so we look at a young child under the 13 age of six. We looked at adolescents who may go 14 to the river and have activities, wading or 15 something there and may be exposed. That would be 16 a group maybe from ten to eighteen years and we 17 also looked at adults. 18 Typically in risk assessments we look 19 at the residents in the area, which is how long 20 would someone be exposed and we include that as 21 part of the assessment. 22 In looking at how people may be 23 exposed, we're dealing with water bodies, so we

There is a specific range that 18 is used to determine whether we're above or below 19 that number and to help make the decisions.

20 We also found that the other exposure 21 pathways that were evaluated also were below — at 22 or below EPA's of level of concern, and what I'd 23 like to do now is turn it back to Rick who's going 24 to talk about another type of assessment.

25 MR. ROBINSON: At EPA, we look at

Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 Page 15 1 both h\iman health and risk to hioman health and the 2 environment. 3 As part of the environment risk 4 evaluation, we conducted a screening level 5 ecological risk assessment, and based on the 6 results of all the sampling data, all the sediment 7 data were below the sediment benchmark criteria 8 which indicated that there were no ecological 9 risks. 10 I just want to go through now and 11 just summarize the presentation. We did not find 12 any radionuclides above background levels in the 13 surface water sediment and wetland areas. 14 The human health risks for 15 radionuclides were at or below EPA's level of 16 concern. 17 The ecological risk from the 18 radionuclides were also below EPA's level of 19 concern; therefore, EPA is proposing a no-action 20 remedy for the surface water and sediment and 21 wetland areas at the site. 22 What we'd like to do now, if you 23 would like to submit written comments on this 24 remedy, my name is up there -- name and address .is 25 up there and Natalie's name and address is up

Submit written comments to us by either 2 mail or email. 3 What we would like to do is open it 4 up for questions right now, but while we are on 5 the record for the operable unit three we would 6 like to address the questions relating to this' 7 remedy. 8 If you have other questions relating 9 to the site of what's going on, we would be more 10 than willing to address those questions after the 11 meeting, so if you want to get the light. 12 I will just leave the information up. 13 LANCE COMAS: My name is Lance Comas, 14 C-0-M-A-S. 15 I'm curious to know what the 16 background levels were and what were the 17 concentrations that radionuclides were detected? 18 MR. ROBINSON: This is Nidal Azzam. 19 MR. AZZAM: The background levels 20 were less than one 1.1 PCI, pico curie per gram. 21 We looked at the average 22 concentration of the samples and they were 23 indistinguishable from each area.

24 MR. ROBINSON: Basically what that 25 means is the levels that we found in the sediments

Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500081 Page 17 adjacent to the site were the same as the m concentrations we found in the five background 3 areas. We didn't see any difference between the 4 sediment samples collected along Newton Creek -- 5 in the Delaware River outfalls and in Martin's 6 Lake. They were all the same as the background 7 areas for radionuclides. 8 BOB SAUNDERS: Bob Saunders, City of 9 Gloucester. 10 Having read the proposed plan and 11 understanding your scope involves the 12 radionuclides and contamination associated with 13 Welsbach, I understand and read that you also did 14 some chemical studies, but I -- correct me if I'm 15 wrong or I guess maybe perhaps I'm 16 misunderstanding, it doesn't appear that there was 17 a full risk assessment done with the chemicals 18 that were detected. 19 MR. ROBINSON: Marian, do you want to 20 address that? 2i SPEAKER: I fully understand that 22 it's not from the scope of Welsbach. I'm not 23 suggesting it is. 24 MR. ROBINSON: Let Marian explain. 25 MS. OLSEN: We did do a full risk

Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500082 500083

Page 18 1 assessment for -- it's called a baseline risk > 2 assessment for the chemicals, and as part of that 3 assessment we looked at ingestion of fish that was 4 potentially contaminated from the river bodies. 5 We looked at ingestion rates for 6 children, young children, adolescents and adults. 7 We did calculate risks from those, but the 8 important thing is that the chemicals that were 9 found were primarily PCB's which have been found 10 in the river system and is the basis for the fish 11 cons\amption advisories and those are not related 12 to the site, and one of the pieces of evidence for 13 that is that PCB's were really not used in the 14 United States until the mid thirties and then 15 through about 1977 when they were banned by the 16. U.S. EPA, so, therefore, they are not related to 17 the activities at the site. 18 MR. ROBINSON: The Welsbach factory 19 went out of business in 1940. 20 SPEAKER: As a point of 21 clarification, I guess, and I'm not arguing the 22 point or suggesting somehow they are associated 23 with Welsbach, but we found this contamination 24 regardless of source and understanding that your 25 scope was pretty much at Welsbach, let's just say

Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 Page 19

1 it was ABC Chemical Company in the '40s, who would m 2 request or as part of the City of Gloucester, say 3 I've been directed to request to get that risk 4 assessment done on those chemicals, based on your 5 data it had nothing to do with Welsbach?

6 MR. ROBINSON: We have done the risk 7 assessment. The risk assessment for that is done. 8 You can review that copy of the risk assessment 9 with all the chemical information. It's in the 10 library. 11 SPEAKER: It's relative to the 12 Federal standards or the state standards or both? 13 MS. OLSEN: It's specifically risk- 14 based because there are -- the federal standards 15 for injunction would basically be the Food and 16 Drug Administration's concentrations and those 17 assume an individual would be receiving fish from 18 multiple sources and our risk assessment approach 19 is we look specifically at someone getting their 20 fish meals directly from the river body that we're 21 investigating and that was evaluated in chapter 22 two of the dociunent risk assessment. 23 MR. ROBINSON: Just to let you know. 24 Bob, we have a representative here from NJDEP who 25 after the meeting, if you would like to talk about

Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500084 Page 2 0 1 some of the issues she'll be available there to 2 answer any of your question. 3 SPEAKER: I understand and agree that 4 they are not associated with Welsbach. 5 MS. OLSEN: If you would like after 6 the meeting I can show you exactly what and show 7 you the data and how it was analyzed. 8 SPEAKER: Thank you. 9 STEVE MARTIRANO: I'm curious. You 10 mentioned Martin's Lake -- we called it "the 11 pond," how contaminants got in there. Is it 12 flowing underground from some -- the top of the 13 hill or what? 14 MR. ROBINSON: What we found, and let 15 me show you the figure over here. This is 16 Martin's Lake right here. On the north shore of 17 Martin's Lake when we did the remedial 18 investigation back in the late '90s we identified 19 a point on the land portion where there was some 20 elevated readings of radionuclides. It's not a 21 large area. It's a pretty small area. It's three 22 feet by three feet. It's only a couple feet deep 23 and the contamination goes down about a foot and a 24 half to two feet and that's the reason why we did 25 the investigation in Martin's Lake itself to make

Fink &'Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500085 Page 21 1 sure that the contamination that we found on the 2 land portion did not extend into the lake itself 3 or the pond itself.

4 SPEAKER: Now, the only thing you are 5 saying to me, then, they were dumping this stuff 6 all over town at that time? 7 MR. ROBINSON: We found contamination 8 across the street on the triangle property between 9 Clemen Highland and possibly when fill was used to 10 fill in that property somebody may have taken a 11 few shovelfuls and filled in a hole over on 12 Martin's Lake area. That's how we are estimating. 13 SPEAKER: They filled that in. That 14 was basically filled in from stuff from 15 Philadelphia, if I recall right, maybe back in the 16 '40s or '50s sometime. This worries me about 17 spots that flow down that you are talking about. 18 There's got to be other contaminants around. 19 MR. ROBINSON: What we have done, we 20 have done a quite extensive stiidy throughout 21 Gloucester City starting with the aerial flyover 22 and that aerial flyover -- I actually have a copy 23 upstairs and I can show you after the meeting that 24 shows the properties and the regional area where 25 there's contamination. And based on that we have

Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500086 Page 22 1 identified a number of properties, and in the 2 beginning designs we then went through old 3 historic maps and looked for where dumping 4 occurred and they matched that up with the 5 radiological flyover and we actually found four or 6 five other properties that were not originally 7 found based on that. 8 SPEAKER: Do you have any information 9 when the dumping quit? 10 MR. ROBINSON: Welsbach went out of 11 business 1940. However, in the late '50s they 12 built the Walt Whitman Bridge. When they built 13 the bridge, they knocked down a niimber of Welsbach 14 buildings. That material, we believe, probably 15 ended up in the jogging track area which was part 16 of a river, so we think a lot of that material 17 ended up in there. 18 Also, we found, based on historical 19 aerial photos, that the triangle property between 20 Clemen Highland, that property there we're seeing 21 dumping as early as the '30s through the '40s, 22 '50s up into the '60s and different generations of 23 waste and from multiple sources.

24 What we also found is in the early 25 '60s when they built the Gloucester City Swim Club

Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500087 Page 23 1 they dug the pools out. The pool materials, I was 2 told by the owner of the property, that that 3 material he knows was put on the property he 4 bought later on, so we have material that we know 5 from the swim club area that had radiological 6 contamination was dumped on the property on Clemen 7 Highland. 8 SPEAKER: Yeah, there was a couple « 9 properties torn down on the other side of 10 Broadway. I know they were found to be badly 11 contaminated, too. I know that because my 12 grandfolks worked there. 13 What I'm saying is, I was just 14 curious if this stuff flows through the 15 underground streams or carry-off? 16 MR. ROBINSON: The one thing that's 17 good news about thorium is that it does not 18 migrate. It's a heavy metal. It does not 19 migrate, so the spot where it was dumped, it will 20 not migrate somewhere else. 21 It also has a low partitioning 22 coefficience, which, in laymen's terms, if it gets 23 into the water it doesn't dissolve like into the 24 water. - 25 MR. AZZAM: Thori\am barely moves in

Fink & Carney Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500088 500089

Page 24 1 soil. It doesn't migrate far. It probably moves 2 one inch every five, ten years. 3 SPEAKER: How about water? 4 MR. AZZAM: It doesn't dissolve in 5 the water. 6 SPEAKER: What does it do? 7 MR. AZZAM: It's metal. It just kind 8 of settles in there. 9 MR. ROBINSON: It just — the thorium 10 stays put. The water will flow around it. The 11 thoriiim stays put. 12 SPEAKER: Basically it's a sold metal 13 is what you are speaking of. 14 SPEAKER: Doesn't it radiate out 15 towards whatever is around it? 16 MR. ROBINSON: Would you please state 17 your name for the record. 18 LORRAINE DiCAMILLO: Lorraine 19 DiCamillo.

20 MR. ROBINSON: Could you repeat your 21 question, please?

22 LORRAINE DiCAMILLO: So the thorium 23 is sitting there under water, let's say, I don't 24 know, what, three feet, a foot, whatever. Doesn't 25 it like radiate like out in all different

Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK •* Fax: (212) 869-3063 Page 25 1 directions? p 2 MR. ROBINSON: Thorium is a 3 radioactive element, and as part of its 4 radioactive decay process it breaks down into 5 other daughter products. Those daughter products 6 release energies either photons, either Alfa Gamma 7 rays, so that is the decay process. That does not 8 spread. That's from that particle and that emits. 9 SPEAKER: That takes 40 billion years 10 or something? 11 MR. ROBINSON: Well, the half life of 12 thorium is 14 billion years, so the amount of 13 thorium that was put on the earth when the earth

# 14 was created, over half of it hasn't gone away yet. 15 That's why EPA is cleaning this up because this 16 stuff won't naturally attenuate. It won't go 17 away. 18 TRACY GRAHAM: I'm concerned about 19 Martin's Lake. You are talking in this back row 20 people of -- generation after generation of people 21 that swam in Martin's Lake. Three of us did. 22 We're old enough, I hate to admit it, but we swam 23 in Martin's Lake and I remember when that lake -- 24 when there was runoff and now it's running off a 25 lot and dirt runs off with it. How about the dirt

500090 Page 26 1 that runs out with that water? 2 MR. ROBINSON: What we found is that 3 there's just a very small isolated portion on the 4 land -- on the northern shore that there's some 5 elevated readings. It's not widespread throughout 6 it. It's only a couple cubic yards worth of 7 contamination most likely. There's not a lot of 8 contamination there that would pose any risk for 9 the activities that you have described. You would 10 have to be living on the soil for a long period of il time. 12 SPEAKER: Is there any possibility of 13 them removing it? 14 MR. ROBINSON: 'Part of the remedy 15 that we'have selected back in the 1999 ROD was to 16 remove the radiological contamination anywhere we 17 found it on the land portions of the site, and the 18 purpose of this remedy was to discuss whether or 19 not the contamination on the land made it into the 20 water bodies that are adjacent to the site and 21 when we went into this we had no idea knowing what 22 Welsbach did with their waste. Did they dump it? 23 Did it end up in the wetlands or did they just 24 dump it on the land, and it appears that it was 25 just dumped on the land and never made it into the

Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500091 Page 27 1 wetlands. 2 BILL WHITLOW: That speaks to my 3 question which is the basis for your selecting the

4 sites that you did for sampling was because of -- 5 I take what you are saying is you don't expect the 6 thorium to migrate either on the surface or in the 7 water but you picked sites because you thought 8 there might have been dumping there? 9 MR. ROBINSON: There were a number of 10 outfalls from the Delaware River. There were 8 11 storm water runout outfalls that would have gotten 12 any rain water from anywhere involved in this 13 area, the vicinity of Gloucester City. We 0 14 measured all the outfalls in the Delaware River. 15 There's also two outfalls that went into Newton 16 Creek that we sampled. We also sampled adjacent 17 to either potentially contaminated properties or 18 known contaminated properties. 19 There's a property that we call the 20 Kumatzu yard on the north part of Broadway on the • 21 north side of the Walt Whitman Bridge. There's a 22 big empty lot in there. There's potential 23 radiological contamination on that property. 24 We've not confirmed it yet, but when we did our 25 wetland studies, we studied sediments along that

i«iiu^ift™f*t>a«asii::;.

500092 Page 28 1 bank. 2 Also along the swim club adjacent to 3 where the contaminated areas are, we sampled right 4 along those. 5 Over on the land preserved portion of 6 Johnson Boulevard we sampled along the sediments 7 and also down north of Nicholson Road and south of 8 Nicholson Road on the south branch of Newton Creek 9 we sampled through there, so anywhere there was a 10 potential for or we knew there was contamination 11 we took samples of the sediments. 12 SPEAKER: Have you done a subsequent 13 aerial survey to evaluate the radiological 14 activity and compare it to what you saw earlier? 15 MR. ROBINSON: We have not done .16 another aerial survey. What we are doing right 17 now is we are doing field investigations. There's 18 1100 properties that the state looked at for -- 19 within the original five study areas that they've 20 come up with in the early 1990's. We found a 21 sixth area which is now Gloucester City, which is 22 the Popcorn Factory parcel where they want to 23 build a middle school. That's what we call study 24 area six. 25 Within those six study areas there's

WJi.ijAii.Vat.-.iilAl-MK'Vii.A-J'i Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500093 Page 29 1 probably over 1200 properties that we — the EPA 2 or the state has looked at, and of those 3 properties our first goal is to study them all

4 with detailed equipment versus a regional kind of 5 a study with a flyover. 6 After we complete those studies, we 7 then clean up those properties. We probably will . 8 not do another confirmatory flyover. 9 If we do one, it will probably be 10 after we complete all the work because when you 11 deal with the radiation you get what's called 12 shine and the shine from a contaminated -- highly 13 contaminated area will block out all the other # 14 contamination around it. You want to remove those 15 higher properties that are contaminated and then 16 you would survey possibly at the end. 17 (At this time, there was an off the 18 record discussion.) 19 MR. ROBINSON: I don't know if that 20 answered your question or not. 21 SPEAKER: Why don't you do a second 22 flyover? 23 MR. ROBINSON: The reason why we 24 don't do another large scale overview is because 25 it won't show you anything different because of

Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500094 Page 3 0 1 the shine from the higher properties. 2 MR. AZZAM: The ground survey is more 3 accurate than the flyover. 4 SPEAKER: That's only if there hasn't 5 been any relocation to fill through the original 6 area. 7 MR. ROBINSON: What we have done, we 8 have a record of aerial photography that goes back 9 from 1930 through basically 2 000 was the last one 10 that we flew. 11 We've compared the aerial photography 12 as time went on to see if areas where new dvimping 13 areas went on and where we know where the 14 contamination is. We have not found any 15 additional new dump areas that could have been 16 opened or areas from when we knew contamination 17 was that was moved. 18 SPEAKER: That sounds like you are 19 limiting it to large scale rather than people 20 taking their dirt and moving dirt from one 21 backyard to another backyard?

22 MR. ROBINSON: Well — Doug, do you 23 have anything you want to add to that? 24 Doug is the design engineer for the 25 Army Corps of Engineers and he's doing the design

4fci!ai'«i*siiwi!.-ai«»i>*t«ili;

»^ 2 MR. ELLEMA: I think the question at 3 hand is with the aerial flyovers and Nidal has 4 already tested this, that the accuracy for the 5 aerial flyover will not pick up the radiological 6 contamination in someone's backyard, let's say, in 7 a small area of my backyard and it was moved over 8 here. That will not show up under any aerial 9 flyover survey. That's why we were doing the 10 ground-based yard-by-yard type survey where we get 11 the accuracy. 12 If we were to refly this, it will 13 only show the same areas that we already know 14 about, the Popcorn Factory, the aerial over 15 Highland Glen and the large sites with the large 16 amounts of radiological materials. It won't tell 17 us anything different than the big sites that we 18 already know. 19 MR. ROBINSON: What it may do, if we 20 remove the contamination and the large areas are 21 removed, there's always a chance that one would 22 see something smaller show up, so I don't know if 23 we will do that. It's something that will have to 24 be considered in the future.

25 KELLY McNICHOLAS: I have a question

Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500096 Page 32 1 about the -- were those, samples outside of the 2 scope of the initial aerial survey? 3 MR. ROBINSON: Which samples? 4 MS. McNICHOLAS: The ones for this . 5 background samples for this part. 6 MR. ROBINSON; Our background 7 samples -- the aerial flyover — actually, I have 8 a copy -- Lisa, can you run upstairs to the 9 bulletin board outside of my office? There's a 10 copy of the aerial flyover up there. 11 The aerial flyover encompassed 12 about -- I believe it was like a 50 kilometer area 13 throughout South Camden, Gloucester City and 14 points east of Gloucester and a number of those 15 areas on -- I believe most of those samples where 16 we took background were within that flyover and 17 after the meeting I can show you the map, and I'm 18 pretty sure that it did include those areas.

19 MS. McNICHOLAS: Was it within the 20 area of concern for that? " My understanding is you 21 took this big picture and then from that big 22 picture you started refining where --

23 MR- ROBINSON: The aerial flyover in 24 '81 identified probably over 20 different 25 properties that the state went out and field

And then in the late '90s when the 4 City of Gloucester was planning on doing --buying 5 a property or I guess they already had the 6 property, they were proposing to place -- some 7 kind of a facility on the Popcorn Factory 8 property. They did a study and found radiological 9 contamination on it. 10 We subsequently looked at the flyover 11 and we found that it was shown on there and that's 12 what led us to go back in our design to any 13 potential areas within the Welsbach that had both f 14 elevated flyover readings and a history of 15 dumping% 16 LORRAINE DiCAMILLO: Now, coal tar, 17 that's not radioactive, right? The coal tar is 18 not a radioactive substance? 19 MR. ROBINSON: No. 20 LORRAINE DiCAMILLO: So, was that 21 contamination there from the PSE&G site as well as 22 the thorium? 23 MR. ROBINSON: Well, if you want to 24 just question about the Popcorn Factory parcel, we

25 can answer that after the presentation regarding

How does 6 that -- how does that play into this and are we 7 confident or should we be confident that the 8 sampling sites for the streams are far enough away 9 from where the contamination was to really reflect 10 a background, a true background? 11 MR. ROBINSON: When we select a 12 background location, it's upgradient and it's 13 not -- Mike -^ we selected -- 14 MICHAEL BARONE: My name is Michael 15 Barone. I work for Malcolm Perry, Incorporated. 16 We selected background locations that 17 were upstream of the known areas of contamination, 18 so there's no possible way they could have been 19 contaminated by any radionuclides from the site.

If there's 2 anything coming in there through that pipe and I 3 think they took care of Martin's Lake -- 4 MR. ROBINSON: It's still there and 5 we sampled the outflow into the river there. 6 That's one of our sampling points. Actually, it 7 runs from Highland Lake across the property 8 between Clemen Highland, then across the jogging 9 track and enters the south branch of Newton Creek. 10 That's the drainage in the area right now — 11 LOUISA LEWELLEN: Is that pipe still 12 there? 13 MR. ROBINSON: Yes. It's a titled 14 pipe. During high tides it does flow into -- from 15 Newton Creek into Highland Lake and in low tide it 16 flows back out. We sampled the sediments from.the 17 outflow of that pipe as part of our investigation. 18 LOUISA LEWELLEN: We are concerned 19 about the way Martin's Lake is not draining.

20 MR. ROBINSON: Right. 21 LOUISA LEWELLEN: Thank you. 22 SPEAKER: I just have a question. 23 What are the benchmark criteria for the ecological 24 risks? How do you do that?

25 MR. ROBINSON: There's a number of

2 after the meeting, but if Mike wants to go -- 3 MR. BARONE: They are in the 4 ecological risk assessment report and they are 5 largely based on literature niombers, based on 6 scientific research. 7 SPEAKER: I don't understand what 8 they are. What are the criteria that you used? 9 MR. BARONE: It's basically 10 benchmarks which are protected of ecological 11 receptors meaning benthic organisms, for examples. 12 A benthic organism is an organism 13 that lives in sediment. 14 SPEAKER: So you are looking at just 15 like the health of a standard wetland or something

16 like that? . 17 MR. BARONE: Yes. 18 SPEAKER: Thank you. 19 SPEAKER: Little Timber Creek, that 20 flows quite a ways up. I was wondering -- it goes 21 around past where there used to be a racetrack 22 which was filled in back in the '90s, 1890's, 23 somewheres around there or a little before that. 24 I imagine probably some of that stuff was dumped 25 in there. There was also a gas pump.

ROBINSON: We are familiar with I» 2 where the racetrack area is and actually where the 3 racetrack area is it's over closer to Gloucester 4 Point, I guess, and over -- what we found is 5 during the clean up of the Popcorn Factory 6 property we found some old historic maps that 7 showed a tributary that went -- of the Delaware 8 River that was called Indian Run and Indian Run 9 ran right up along where the racetrack area was 10 and up through the Popcorn Factory parcel and then 11 north. That was filled in in the 1890's through 12 the 1900"s and we found some radiological 13 contamination in Indian Run in a couple locations, 14 one at the Popcorn and one across the street over 15 off of 7th Street between Jersey and Charles. 16 Thank you. 17 18 (Hearing concluded.) 19 20 21 22 23 24 25 L I Fink & Camey Reporting and Video Services 39 West 37th Street * New York, New York 10018 (800) NYC-FINK * Fax: (212) 869-3063 500103 Page 39 1 CERTIFICATION 2 3 I, Deborah McNally, do hereby certify that 4 the witness in the foregoing deposition was duly sworn to 5 testify the truth, the whole truth and nothing but the 6 truth in the within-entitled cause; that said deposition 7 was taken at the time and place therein stated; that the 8 testimony of said witness was reported by me, a Certified 9 Shorthand Reporter and Registered Professional Reporter, 10 and was thereafter transcribed under my direction into 11 typewriting, and that this is a true and correct 12 transcript of same. 13 I further certify that I am not counsel 14 for, nor in any way related to any of the parties to this 15 suit, nor am I in any way interested in the outcome 16 thereof. 17

Most of you are — msybe — many of PRESENTATION BY JOHN PRINCE t 6 you may be aware of the fact that there is another 5 PAGE 18 7 superfimd site in Camden — the City of Clamden, 6 8 particularly in this portion of the — in tiiis 7 g 9 portion of Camden, Waterfront South, there is flie 9 10 general Gas Mantle Facility and since we were coming 10 11 here to talk about Martin Aaron and the proposed plan 11 12 to address contamination at the Martin Aaron Site, we 'l2 13 thought it fitting that we also discuss the woik diat 13 14 is - the proposed plan rather for contamination at 14 15 the Welsbach Site, so this meeting actually will be 15 16 covering both the Martin Aaron Superfimd Site and the 16 17 Welsbach - a portion of the Welsbach Site. 17 18 We're going to start with the Welsbach IS 19 portion and then we'll move on to the - to the 19 20 Martin Aaron portion of the everiing. 20 • 21 We have a - since this is a public 21 22 meeting and we are going to be discussing a proposed 22 23 ' 23 plan, all of this information is being recorded by 24 24 our court reporter, so I would ask that at the end of 25 25 the presentation ^^ilen we do the Q and As that you Pages 2 to 5 [email protected] Mastroianni & Formaroli, Inc. 856-546-1100 Professionals Serving Professionals 500106 July 26,2005

This is the agenda for the evening. For 3 investigation and feasibility study. 4 the Welsbach portion of the presentation. Rick 4 What that basically is is we go out and 5 Robinson, wiio is the remedial project manager for the 5 gather information, actually go to Ae site and do 6 Welsbach Site, will be coming to talk about — talk 6 pretty extensive investigation, sampling, that sort 7 about — give you flie information about the projxjsed 7 of thing and that information helps us to determine 8 plan for Welsbach. 8 the nature and extent of the contamination and that 9 I wanted to go over with you all 9 information is the basis for the proposed remedial 10 briefly, it looks a little bit confiising but it 10 action plan which is what we're talking about this 11 really isnt, this is the milestones in the siq>erfimd 11 evening. 12 process and I just wanted to talk briefly about where 12 The proposed remedial action plan, once 13 we came from and wiiere we are with regard to the- 13 we've defined the nature and extent of contamination 14 to. the continuum of the life cycle of a superfimd 14 at the site, we then have to figure out well, what's 15 site. 15 the best way of addressing it, what's the best way of 16 Initially, there's a — >*iienever a 16 cleaning up the site. 17 superfimd site comes into existence, it usually 17 We put together this document that looks 18 starts off with discoveiy. Many times a site might 18 at available technologies and what is die best 19 be identified by a state entity, the New Jersey 19 approach to addressing contamination at any 20 Department of Environmental Protection, sometimes it 20 particular site. 21 may even be a concerned citizen that notifies EPA and 21 Tonight, we're going to be presenting 22 we begin an investigation and we may — it may 22 that proposed plan, that proposed remedial action 23 actually turn out to be something more and may become 23 plan, what does EPA Aink is the best way to address 24 a superfimd site. 24 the cleanup. And we're going to be talking about the 25 Once a site discovery takes place, we go 25 Martin Aaron Site and in addition the Welsbach Page 7 Page 9 \^ 1 through something called a preliminary assessment and 1 Facility. 2 a site inspection. What h^pens in the preliminary 2 Once we've completed this proposed 3 assessment is that we begin to collect any available 3 remedial action plan, there will be a document 4 data and information about any known or suspected 4 forthcoming called the record of decision. That is 5 releases at that facility. The technical phase 5 the document that says, well, EPA — we — ftisi s 6 follows the site inspection v/here we actually go out 6 the — this is what we believe is the best remedy, 7 and do preliminary inspection of the site. 7 this is the decision that has been made out of 8 That information is put together in 8 those - the series of alternatives for cleanup, this 9 something — and we go through something called a 9 is the one that has - we've decided oa 10 hazardous ranking ~ hazard ranking system. That- 10 Once we've made our decision as what — 11 that information, gleaned from the information search 11 how to clean up the site, we then go into Ae latter 12 in the site inspection, each site is scored and once 12 phases ofremediationofa site, actually designing 13 it gets a particular number, it then qualifies for 13 Aat particular -that particular cleanup and then 14 and is then listed on the >JPL, the National 14 moving on to actually building it, w^iatever — or 15 Priorities List, which is a list of all of the 15 whatever flie — whatever the selection is. If it 16 superfimd sites in the country. 16 requires construction on site or off site, thaf s 17 Martin Aaron has gone through this 17 this phase. 18 process and — both Martin Aaron and Welsbach have 18 We then - once we've gone through all 19 gone through this process and they were both listed 19 of th|f;and the actual cleanup begins, goes into the 20 on the NPL making them federal superfimd sites, they 20 operaiion & maintenance mode.

Dear Mr. Robinson,

I read the EPA bulletin (#05064) released May 26, 2005 regarding the cleanup of the above site.

We live in Haddon Township, Camden County NJ, which is within 10 miles of the cleanup site in Gloucester and Camden. Over the past several years we have noticed a number of crippled, disfigured and otherwise handicapped Mallard ducks in our area which we did not see previously. We know that ducks in our area transit to and from the Delaware River in that area, because this past winter we saw 5 or 6 of them in our lake and creek that came in contact with the oil spill that occurred in the river. One was captured and taken to Tri State Bird Rescue and Research in Newark, Delaware where he was treated and then we released him back in our area.

My question is whether the study that was performed to determine the level, extent and impact of the contamination included study of affects on wildlife, and whether or not the abnormalities seen in the Mallards are in any way linked to the contamination.

Thanks for considering our question and concem.

Dear Rick, Natalie and Marian, Thanks for the information about the Welsbach site. You all did an excellent job of presenting information and of listening to the community. I hope you get credit within your agency for that; in my experience, it is a very unusual to find at EPA someone who actually listens.

From the perspective of public communication, I do think it would be extremely helpful for the agency to do a follow-up assessment of contamination levels, so you could show, in a simple and direct fashion, what the contamination level was that put Welsbach/General Gas Mantle on the NPL, and what it is now, after your remediation efforts (as well as what your target level was). It should show that you've done what you are supposed to do. Frankly, I find all the discussion about the technical details of one remediation effort or another is the sort of information that makes my eyes glaze over, without giving me a satisfactory answer to the question of whether the threat has been abated.

Thanks again, Bill Whitlow

Re: Comments for Welsbach/General Gas Mantle Contamination Site Proposed Cleanup Plan for 0U3

Dear Mr. Robinson:

Attached, please find comments prepared by Chapin Engineering on behalf of Edison Wetlands Association regarding the proposed cleanup plan for Welsbach/General Gas Mantle Contamination Site.

As a non-profit organization advocating for enviroiunental justice and proper cleanup of contaminated sites throughout New Jersey, we are concerned by EPA's No Action proposal for OU3 and recommend that you reconsider the decision based on the comments provided by Chapin Engineering.

Sincerely,

Robert Spiegel Executive Director

R.W, Chapin, P.E. President MEMO TO: Bob Spiegel, Edison Wetlands Association FROM: R.W. Chapin, P.E. DATE: 09/14/05 RE: Welsbach/General Gas Mantle Superfimd Site, Camden, NJ Review of Proposed Remedial Action, OUS, dated May 2005

According to the USEPA's Proposed Plan, the Welsbach Site consists of two former gas mantle manufacturing sites (Welsbach and General Gas Mantle) and "ntunerous" other properties in Camden and Gloucester City, NJ proximate to these former manufactiuing locations. The companies used radioactive Thorium to manufacture gas mantels that would glow brightly. The tailings fi-om the processing of Thorivmi ores and other radioactive wastes are the contaminants of concem for the Welsbach site.' Welsbach operated from 1895 until 1940, while General Gas Mantle operated from 1912 to 1941.

The USEPA issued its summary of its proposed remedial action for Operable Unit 3 (the "EPA Stmimary") in May 2005. The EPA Summary presents of the preferred altemative for addressing contaiiiination of surface water, sediment and wetlands areas at the Welsbach site, including a rationale for its sielections. The selected remedy is No Action. This selected remedy was presented and discussed at the July 26, 2005 pubhc meeting in Camden. This memo provides comments on the EPA Summary, which is 11 pages in length and includes one figure, as well as comments based on information provided at that meeting. . The proposed remedial action for the Martin Aaron Superfimd Site was also presented and discussed at the July meeting.

The selected altemative is No Action. This is based on the EPA finding that radionuclide concentrations in the sediment samples were essentially no different than "background"; consequently, neither the hvmian health nor ecological risk assessment foimd vmacceptable risks.

The EPA investigations of Operable Unit 3 (0U3) included analysis of samples for "Chemical contaminants", although the list of specific chemicals is not stated. The EPA found that PCBs are the "main chemical contaminant" in the sediments that exceed EPA's "level of concem" for human health risk. No other chemical is discussed, and EPA stated that PCBs are not associated with the Welsbach site, hi general, the EPA states that no chemical contaminant found by their investigation is associated with the Welsbach site, and does not address any chemical contamination in their proposed remedy. This is also the case for the ecological risk assessment, although "a number of chemical contaminants" exceeded ecological impact guidelines.

Conmients on the Welsbach proposed plan follow.

MEMO TO: Bob Spiegel, Edison Wetlands Association FROM: R.W. Chapin, P.E. DATE: 09/14/05 RE: Welsbach/General Gas Mantle Superfimd Site, Camden, NJ Review of Proposed Remedial Action, 0U3, dated May 2005

• During the pubhc meeting it was revealed that radioactivity had been discovered at the Martin Aaron site, which is roughly Vi mile north of the General Gas Mantle site, and within Study Area 1 of the Welsbach Superfimd site. No acknowledgement of this fact was provided in the pubhc handouts for either site. A complete set of the radiological data for the Martin Aaron site should be included in the Martin Aaron RA Selection report. Additionally, the impact of this radioactive inaterial on the proposed disposal of martin Aaron soils mtist be evaluated. The likely origin of the radioactivity at the General Gas Mantle site indicates this assessment should be part of the Welsbach site activities.

• The EPA expended fimds collecting and analyzing sediment and surface water samples for chemical contaminants then expended fimds to conduct himian health and ecological risk assessments for those chemicals. Why these fimds were expended when there was no intent to use the data should be explained. In addition, this data must be fransmitted to the NJDEP.

• EPA states that the chemicals foimd in their samples were not in use when Welsbach and General Gas Mantle operated, apparently as its justification for not considering their chemical data when evaluating cleanup options. Both of these facilities had to have used coal and would, therefore, have produced PAH compoimds in their coal ash. PCBs, according to the USEPA web site, were manufactured from 1929 to 1977, and their presence/use at these sites cannot be excluded. Widespread use of DDT as a pesticide commenced in 1939 (although the compoimd was created circa 1874). The blanket exclusion of Welsbach as a potential source of chemical contaminants is not justified. The potential contribution of the Welsbach site to the contaminated sediments requires an evaluation.

Re: Record of Decision (ROD) for Operable Unit #3 Wel.sbach/General Gas Mantle Contamination Superfund Site Gloucester City & Camden, Camdoi County

Dear Mr. Steinberg:

The New Jersey Department of Environmental Protection (Department) has completed review of the July 2005 Draft Record of Decision (ROD) for Operable Unit #3 (0U3), the surface water, sediment and wetland areas. We are pleased to concur with the chosen remedial alternative.

The chosen remedial alternative for 0U3 is the no action remedy described in the ROD document and applies to the third of four planned operable units for the Welsbach site. As stated in the ROD, the U.S. Environmental Protection Agency (EPA) has determined that no site-related contaminants ofaoncem are present at elevated levels in the surface vvaler, .sediment, and wetland areas adjacent to the Welsbach Site. Therefore, no remedial action is warranted, because there is no radiological conumination in tlie surface water, sediment, and wetland areas adjacent to the Welsbach Site that pose an unacceptable risk to human health or environment.

We appreciate the opportunity lo participate in the remedial decision making process and ihc efforts of USEPA lo address this contaminated site.

Ifyou have any questions, please do not hesitate to call me at (609) 292-1250.
