Section 1 Introduction This report serves as a supplemental document to the Final Screening-Level Ecological Risk Assessment (SLERA) Report (CDM 2006) conducted for the Consolidated Iron and Metals Superfund Site (the site). The final SLERA report indicated that there is a potential for ecological risk at the site. The purpose of this supplemental document is to proceed to the next step in the Ecological Risk Assessment process, which involves refinement of the contaminants of potential concem (COPCs) and further characterizing the potential for ecological effects.
Environmental Protection Agency (EPA) guidance recommends using the findings of a SLERA as the basis of a scientific/management decision point (SMDP) to determine the next steps in the ecological risk assessment process (EPA 1997). During a phone conversation with EPA and National Oceanic and Atmospheric Administration (NOAA) on June 27, 2006, the next steps in the ecological risk assessment process were discussed. It was decided that the next step, specifically Step 3, would be completed for sediment in the Hudson River adjacent to the site, as described in EPA (2001). This report provides the results of the refinement of the COPCs.
The approach used to refine the selection of COPCs for the site involved five basic modifications from the Final SLERA Report (CDM 2006a). The modificahons are listed below:
• Refinement of exposure point concentrations • Normalization of sediment screening values using average site-specific total organic
carbon (TOC) concentrations • Consideration of background concentrations • Consideration of site-related contaminants • Refinement of screening benchmarks
The COPCs identified for sediment following the refined evaluation for the site are summarized in Table 3-1.

Section 2 Modifications Details regarding the modifications made to the refined COPC selection process are presented below.
2.1 Exposure Point Concentration In the Final SLERA report, the maximum detected values of contaminants in sediment were compared to screening benchmarks. In the refined COPC selection, the mean concentration for each chemical was compared to its screening benchmark. The use of the mean concentrations for calculating exposure point concentrations is more representative than the use of maximum concentrations.
2.2 Total Organic Carbon in Sediment The bioavailability of organic compounds decreases as the organic content of sediment increases. In the Final SLERA, the lowest total organic carbon (TOC) concentration measured at the site (1.2 percent) was used to normalize screening benchmark concentrations for organic compoimds. In the refined COPC selection for sediment, the average, site-specific TOC concentration (3.73 percent) was used, providing a more realistic estimation of the potential risk from contaminants at the site.
2.3 Background Concentrations In the Final SLERA Report, background concentrations of contaminants were not considered. In the refined COPC selection, the mean background concentration for each contaminant was calculated and contaminants having a mean detected concentration lower than the background value were removed from consideration as COPCs. One half of detection limit was used for non-detects.
2.4 Site-Related Contaminants In the Final SLERA Report, whether the contaminants were site related was not considered. In the refined COPC selection, the non-site related contaminants were eliminated as COPCs (see Table 3-1). The site-related contaminants identified in the Final RI Report (CDM 2006b) are the following:
• Polycyclic Aromatic Hydrocarbons (PAHs): benzo(a)anthracene, benzo(b)fluoranthene, benzo(a)pyrene, indeno(l,2,3-c,d)pyrene, and dibenz(a,h)anthracene
• Polychlorinated Biphenyl (PCB): Aroclor-1254 • Metals: arsenic, cadmium, copper, iron, lead, mercury, vanadium, and zinc
2.5 Screening Benchmarks In the Final SLERA Report, conservative screening benchmarks among sources considered were used to calculate hazard quotients (HQs). In the refined COPC selection, the following widely accepted and used benchmark sources that contained screening values for the compound(s) of interest were considered:

Section 3 Refined Chemicals of Potential Concern Selection The refined list of COPCs, the reason for their selection/exclusion, contaminant concentrations, and background concentrations are discussed in this section.
Using a conservative approach, the Final SLERA Report indicated that the potential for ecological risk exists in sediments in the Hudson River adjacent to the site (CDM 2006a). A scientific and management decision was made during a conference call with EPA's Biological Technical Assistance Group (BTAG) to refine and re-evaluate COPCs identified in the SLERA using supplemental information and site-specific parameters, as discussed in EPA (2001). Modifications made from the Final SLERA Report are listed in Section 1.
Table 3-1 lists statistical information of COPCs identified in the SLERA, mean and background concentrations, HQs based on mean concentration of these contaminants, HQs based on the background concentrations, and justification and comments for selection or exclusion of each chemical or analyte as a COPC in this refinement.
As shown in Table 3-1,32 COPCs [1 volatile organic compound (VOC), 17 semi-volatile organic compounds (SVOCs), 4 pesticides/PCBs, and 10 inorganicsj identified in the SLERA have HQs equal to or less than one, indicating they are not considered COPCs in the refinement. Five contaminants (benzaldehyde, carbazole, endrin ketone, thallium, and vanadium) do not have screening values. The mean concentration of vanadium (25.5 mg/kg) was lower than the backgroimd concentration (26.1 mg/kg) . Thus, vanadium is eliminated as a COPC. Benzaldehyde, carbazole, endrin ketone, and thalliimi, are also excluded as COPCs because they are not associated with site operations and are not considered site-related contaminants.
Four contaminants (dibenzofuran, dimethylphthalate, 2-methylnaphthalene, and cyanide) having mean concentrations below their respective mean background concentrations. Therefore, they are excluded as COPCs.
Three contaminants (acetone, acenaphthylene, and 4-methylphenol) were present at concentrations exceeding their respective screening levels. However, these three compounds were detected very infrequently in soil samples at the site, indicating that these three contaminants in sediments in the Hudson River likely did not originate from site soils. Furthermore, the RI Report (CDM 2006b) indicates that these contaminants are not associated with site activities. Therefore, they are also eliminated as COPCs in this refinement.
One SVOC (butylbenzylphthalate) and four inorganics (manganese, seleniimn, silver, and zinc) are also excluded from the refined COPC list, because they are not considered site related in the RI Report. In addition, screening level exceendances for these five contaminants were low, with calculated HQs ranging from 2.3 to 1.1.

Section 3 Refined Chemicals of Potential Concern Selection
Benzo(b)fluoranthene and copper may be considered COPCs in the refinement. The calculated HQs for these two contaminants are below 10 (8 and 3.2, respectively). In background samples, the mean backgroimd concentration of benzo(b)fluoranthene also exceeds its screening criterion (HQ = 5.3). Therefore, a calculated net H Q from this contaminant is low (2.7).
Two contaminants (benzo(b)fluoranthene and copper) have been determined to be site related and could be considered COPCs in this refinement. However, copper has a low HQ (3.2). For benzo(b)fluoranthene, the mean concentration and background concentrations are 3,094 and 2,061 Mg/kg, respectively, resulting in HQs of 8 and 5.3, respectively. The difference between these HQs is 2.7, which indicates the potential for risk is extremely low. Furthermore, previous investigations conducted at the Newburgh manufactured gas plant (MGP) hazardous waste site immediately down river of the Consolidated Iron site indicated that PAHs and inorganics were contaminants of concem (COCs). Benzo(b)fluoranthene and copper were generally detected in Hudson River sediment samples at much high levels adjacent to the MGP site. It is likely contaminants from the MGP site were transported upriver with the tidal flow and deposited near the Consolidated Iron site. Therefore, these two contaminants in sediment may have originated at the MGP site.
Using the approach described herein to refine the list of COPCs at the site, detected contaminants fall into several groupings, as shown on Table 3-1 and svunmarized below.
• Most contaminants present in sediment are at concentrations below screening values; their HQs are below 1, indicating no risk concems.
• Several contaminants (acetone, acenaphthylene, and 4-methyIphenol) have relatively high HQs, but are not site related contaminants, based on limited or no detections of these contaminants in site soils.
• Several contaminants (butylbenzylphthalate, aluminum, manganese, seleniimi, silver, and zinc) minimally exceed screening values, with HQs in the range of 1 to 3, which is indicative of very low potential for risk.
• Several contaminants (benzaldehyde, carbazole, endrin ketone and thallitun) lack screening values, but are not site related, based on limited or no detections of these contaminants in site soils.
• Two compounds (benzo(b)fluoranthene and copper) exceed screening criteria, with relatively low HQs (2.7 and 3.2, respectively), indicating low potential for risk.
Based on the refinement of COPCs described in this Addendtun to the SLERA, only two contaminants - benzo(b)fluoranthene and copper - are site-related COPCs. Both have low HQs and show low potential for risk to receptors in the Hudson River sediments. Therefore, CDM recommends that a Baseline Ecological Risk Assessment (BERA) should not be conducted for Hudson River sediments.
