This rule amends the regulation by allowing interim progress reports to be due in 60 days, instead of the current 30-day requirement, following the close of the quarterly and semi-annual reporting periods. In addition, this amendment allows the recipient of a Superfund State Contract (SSC) to request that EPA apply any overpayment of cost share to another site. The revisions affect States, Indian Tribes, intertribal consortia, and political subdivisions. The revisions will improve the administration and effectiveness of Superfund Cooperative Agreements and Superfund State Contracts.
