RISK ASSESSMENT SUPPORTING THE FINAL RULE FOR SOLVENT-CONTAMINATED WIPES.
Impact/Purpose:
The risk analysis will be used to support the development of a final rule for solvent-contaminated wipes. To ensure the adequacy of the modeling and solvent concentrations, the analysis was peer reviewed by external reviewers.
Description:
This analysis evaluates potential risks due to release of solvents from laundry sludge and disposable wipes sent to a landfill. Receptors for air and groundwater in lined and unlined landfills were evaluated. The potential solvent concentrations were calculated to determine the solvent loadings from the wipes and sludge. The mass based solvent quantity loadings were compared to the risk based loadings to determine the risk potential for specific solvents. This risk analysis also addressed previous peer reviewers’ and general public comments on the initial risk assessment conducted for the proposed rule. The final rule, supported by the risk assessment, will be prepared after the consideration of all comments for the proposed rule and the risk analysis Notice of Data Availability.
