## Docket Report September 30, 2010 Owosso Graphic Arts (Owosso), Owosso, Michigan Delisting Petition RE: Risk Evaluation for Mismanagement in a Subtitle D Landfill The Environmental Protection Agency (EPA) used the Delisting Risk Assessment Software (DRAS) version 3 to evaluate Owosso's petitioned waste. EPA entered site-specific parameters into DRAS including maximum annual waste volume and maximum observed total concentrations of hazardous constituents in the waste. EPA usually incorporates separate leachate data from analysis of waste samples, however, in this case, EPA conservatively estimated leachate concentrations from total concentrations. EPA divided the totals concentrations by 20 to approximate the TCLP method (which includes a 20-fold dilution with an extraction fluid). This approach conservatively assumes that all of each metal or chemical in the waste will dissolve into the extraction fluid. EPA also entered Region 5 specific target cancer and hazard levels (1x10-6excess cancer risk for individual chemicals or metals, lx10-5

## excess aggregate cancer risk, hazard index of 1.0) into DRAS. The program output is attached. Please note that the Owosso analytical data for total concentrations was adjusted to a dry-weight basis for use in the DRAS software. The waste analysis conducted by Owosso indicated the presence of a waste constituent not pre-loaded in DRAS (n-methyl-2-pyrrolidone - NMP). EPA reviewed several sources, including EPA's Integrated Risk Information System (IRIS), for any indication of NMP-toxicity. California EPA has published Maximum Allowable Dose Levels (MADLs) for NMP from exposure via inhalation and dermal exposure. EPA added NMP to DRAS and researched physical, chemical, fate, and transport parameters needed by DRAS to conduct the analysis. The parameters used are summarized after this narrative. The concentration for NMP used in the DRAS was adjusted to dry weight using the minimum % solidsreported for earlier samples of this waste submitted in support of the petition. The NMP concentration also includes tentatively identified compounds (TICs) that were similar to NMP in analytical retention time and mass spectra as these may be derivatives of NMP in the waste. The aggregate cancer risk and hazard index for the petitioned waste meet the criteria set by Region 5. The risk analysis estimated the total aggregate cancer risk from constituents detected in the waste to be 4.12x10-6, below EPA Region 5's target aggregate cancer risk of lx10-5. The risk analysis estimated individual constituent cancer risks generally well below EPA Region 5's target of lx10-6with the single exception of arsenic (just over at 4.05x10-6). The analysis estimated total aggregate hazard index (a sum of hazard quotients) from constituents detected in the waste to be 0.583, below EPA Region 5's target of 1.0. Note that the final aggregate calculation does not agree with the final table Aggregate Risk and Hazard Quotient Results from DRAS version 3.0. To be conservative, the Agency ran DRAS 3.0 with all three types of chromium and arsenic from the DRAS database each at the maximum observed concentration. This was done in order to obtain the most conservative maximum allowable total and TCLP concentrations for these metals. We included only the species of arsenic or chromium resulting in the greatest cancer risk or hazard quotient in the final aggregate calculation. A spreadsheet showing the revised aggregate calculation is attached.

## Attachment 2 Aggregate Risk and Hazard Quotient Results Revised to Correct for Summing Calculation

September 30, 2010Aggregate Risk and Hazard Quotient Results Owosso Graphic Arts Page 1 of 1 9/30/2010 Revised to Correct for Summing Calculation:
1. Summing algorithm not affected here since there were no non-detected values 2. Correction eliminates multiple entries for individual metals (i.e. Cr, Cr(III), Cr(VI)) by choosing the most conservative.
