ATTACHMENT A 
to July 15, 2008 Hearing Officer Order 
AS 08-10, RCRA Delisting Adjusted Standard Petition of Peoria Disposal Company 
1.    
Please describe any treatment operating guidelines Peoria Disposal Company 
(PDC) has concerning curing times based on weather conditions. 
2.    
Please explain PDC’s position on whether its shipments of electric arc furnace 
dust stabilization residue (EAFDSR) that meet delisting levels would be subject to 
the Board’s “special waste” regulations, including manifesting requirements (35 
Ill. Adm. Code 808, 809). 
3.    
Please comment on the appropriateness of including a condition in the adjusted 
standard language requiring that PDC, before transporting an initial load of 
delisted EAFDSR to a given disposal facility, provide the Illinois Environmental 
Protection Agency (IEPA) with a one-time written notification identifying that 
disposal facility. How many days before transporting those initial loads to the 
respective disposal facilities can PDC reasonably provide such notification? 
4. Please comment on the appropriateness of requiring PDC to provide IEPA with 
written notice of any “significant change” and the results of the related bench-
scale treatability testing prior to operating full-scale treatment using the new 
chemical regimen. 
See 
proposed condition 3(b). 
a. PDC’s petition states that “significant change” would “mean the 
utilization of a chemical treatment regimen containing different active 
ingredients.” Petition at 18. Please explain whether this definition of 
“significant change” should be a part of the adjusted standard conditions. 
b. PDC has provided a “Reagent Constituent of Concern Evaluation” in its 
petition for the current recipe. Please comment on how verification under 
proposed condition 3(b) would ensure evaluation of potential constituents 
of concern (COCs) when changing the chemicals used by PDC in the 
treatment process. 
5.    
Please comment on the appropriateness of including a condition in the adjusted 
standard language requiring PDC to submit annually to IEPA the data (and/or a 
summary of the data) collected pursuant to proposed condition 3(c). 
See 
67 Fed. 
Reg. 1888, 1895 (Jan. 15, 2002) (Heritage Environmental Services, LLC 
delisting, ¶B(4) ).
6 
6.    
Hexachlorophene, which is a 40 C.F.R. Appendix IX constituent that is not a 
chlorinated pesticide or herbicide, does not appear to be in PDC’s analytical 
results. Please address sampling and analysis for hexachlorophene. 
7.    
PDC’s Technical Support Document (TSD) (Petition Attachment 2) refers to two 
federal delistings involving chemically-treated EAF dust: Heritage 
Environmental Services, LLC (Heritage) on January 15, 2002 and Conversion 
Systems, Inc. (CSI) on June 13, 1995. TSD at 4-9. Although the TSD refers to its 
Appendix C for more information on these delistings, Appendix C does not 
contain the relevant material. Please provide the information referred to at 4-9 of 
the TSD regarding the federal delistings for Heritage and CSI. 
8.    
The “EPA RCRA Delisting Program Guidance Manual for the Petitioner” dated 
March 23, 2000, states that “a final list of constituents can be prepared to include 
only the metals and organics from the 40 CFR 261.24 Toxicity Characteristics list 
plus all additional constituents that were detected in the first sample when 
analyzed for totals concentrations of constituents on the initial list.” Manual, 
Appendix H, Attachment 2. 
a.    
PDC detected dioxins and furans in EAFDSR samples but the constituents 
were not included in the final list of COCs. In an email dated 1/31/08, 
Todd Ramaly of the United States Environmental Protection Agency 
(USEPA) Region 5 commented on excluding dioxins and furans from the 
final list of COCs: “we’re not sure of this conclusion and did not yet 
agree that DF are no longer an issue.” TSD Appendix C. Please describe 
any resolution PDC may have reached with USEPA concerning dioxins 
and furans not being on the final list of COCs. 
b.    
Bis(2-ethylhexyl)phthalate was detected above both the Method Detection 
Limit (MDL) and the Estimated Quantitation Limit (EQL), but was not 
included in the final list of COCs. Although semivolatile organic 
compounds (SVOCs) are discussed generally in the TSD at 4-6, there is no 
specific reference to bis(2-ethylhexyl)phthalate. Please explain why bis(2-
ethylhexyl)phthalate was not included in the final list of COCs. 
9.    
In a communication record dated 1/24/08, PDC’s consultant, RMT, summarizes 
the agenda for a conference call between PDC, RMT, IEPA, and USEPA. One 
point states: “With comparison to Illinois Tiered Approach for Corrective Action 
(TACO) screening values and DRAS [Delisting Risk Assessment Software] v.2 
values, the results from the SAP [Sampling and Analysis Plan] implementation 
provided supports analytical results to exclude additional constituents of concern 
(COCs) other than the 14 metals listed in the SAP/QAPP [Quality Assurance 
Project Plan].” TSD Appendix C. In an email response, Todd Ramaly of USEPA 
Region V commented on the draft by striking the above sentence and adding, 
“[Laura – I don’t think we discussed this last point during the call.]” TSC 
Appendix C (email from Ramaly to Curtis dated 1/13/08). Please describe any
6 
resolution PDC may have reached with USEPA concerning this approach to 
excluding detected constituents as COCs. 
10.   
The values for dioxin and furan congeners and toxicity equivalency quotient 
(TEQ) in Table 3a and Appendix L of the TSD do not seem to agree with the raw 
laboratory data from Pace Analytical in Appendix N of the TSD. Please reconcile 
the raw data with the summarized data. 
11.   
The TSD indicates the TEQ value of 160 ng/kg was used in the spreadsheet 
calculation model for the dioxin fish ingestion pathway. Please comment on 
whether the higher value of 220 ng/kg (Sample R5-01) reported in the Pace 
Analytical raw laboratory data should be employed in the evaluation. If it should 
be, please provide revised input and results and address the resulting carcinogenic 
risk “Fishing CR,” “Fish Concentration Edible Portion,” and “Fishing DL” of the 
revised values. If PDC provides revised results, please update the comparison 
with the table “Background Dioxin Concentrations in Fish Tissue” presented in 
Appendix H of the TSD. 
12.   
Based on the TCLP results of the dioxin/furan analyses, please comment on how 
the highest value of 0.052 pg/L (TSD Appendix N, Sample R1-04, 1064827002, 
12/07/07) compares to the groundwater adult dermal pathway that was determined 
as a limiting pathway by the DRAS v.2 analysis of 2.05 x 10
-10 
mg/L in Appendix 
H of the TSD. Also, please compare how the detected TCLP value of 0.052 pg/L 
compares to the revised “Fishing DL” in the dioxin spreadsheet calculation 
model. 
13.   
Please provide all of the pages from each of these DRAS runs: 2/20/08 (Arsenic) 
and 2/19/08 (Screening Levels to Identify COCs). 
See 
TSD Appendix H. 
14.   
In a communication record dated 1/24/08, RMT summarized the agenda for a 
conference call between PDC, RMT, IEPA, and USEPA. One point states: “PDC 
requested discussing how to handle . . . altering delisting criteria acceptable by the 
Agency (i.e., arsenic concentration based on 1 x 10-5 risk). It was decided that a 
conference call on 1/28/08, after the Agency call on 1/25/08 would be scheduled 
for the purposes of providing the path forward and technical answers regarding 
the DRAS model.” TSD Appendix C. Please describe any resolution PDC may 
have reached with USEPA or IEPA concerning altering the delisting criteria for 
arsenic. 
15.   
PDC’s proposed adjusted standard language specifies TCLP concentrations not to 
be exceeded for 14 metals. Unlike the federal delisting for Heritage, however, 
PDC’s proposed language does not contain a delisting level for total mercury. 
See 
67 Fed. Reg. 1888, 1895 (Jan. 15, 2002). 
a.    
Please quantify the contribution from mercury to the aggregate hazard 
index.
6 
b.    
Please comment on the appropriateness of including a delisting level for 
total mercury. 
16.   
PDC premises its dioxin modeling for the fish ingestion pathway on disposal in 
the Indian Creek Landfill. The proposed adjusted standard language, however, 
does not limit disposal of EAFDSR to that landfill. Please consider re-running the 
model using the default generic values for a less site-specific analysis. If PDC 
wishes to use site-specific information in its modeling, rather than the default 
generic values, please consider either providing site-specific modeling for all the 
potential Illinois landfills at which the EAFDSR might be disposed, or limiting 
the proposed adjusted standard language to only those disposal facilities for which 
site-specific modeling was performed. 
17.   
References in the proposed adjusted standard language to the “mechanical mixer” 
and the “K061 stabilization process described in its Petition” (
see 
proposed 
condition 2) could encompass the stabilization process that PDC has used for the 
past 19 years. Please comment on the appropriateness of more narrowly-tailoring 
the adjusted standard language to PDC’s “new proprietary stabilization 
technology,” subject to proposed condition 3(b). Petition at 2. As appropriate, 
please propose amendatory language. 
18.   
Proposed conditions 3(c)(1) and (2) each refer to “another round of verification 
sampling and analysis.” Please clarify whether these additional rounds would 
include testing for all COCs or only for those that exceeded the delisting 
concentrations in the prior round. If PDC is proposing the latter approach, please 
explain how PDC will verify that over-treatment has not increased the solubility 
of other metals that may be amphoteric. 
19.   
PDC states that its proposed adjusted standard language requires that the delisted 
EAFDSR be disposed of in a lined landfill with leachate collection in Illinois that 
is “licensed, permitted, or otherwise authorized to accept the delisted waste in 
accordance with all applicable RCRA Subtitle D requirements.” Petition at 19. 
Please explain what types of landfills other than permitted landfills PDC believes 
would be able to accept the delisted EAFDSR.
