This talk will give a brief overview of the performance-based measurement approach to project planning and analytical methods selection and how it applies to the RCRA Program. It will also cover the basic changes to the RCRA regulations as a result of the promulgation of the Methods Innovation Rule (MIR) on June 14, 2005 and its effect on the regulatory and regulated communities, particularly enforcement and compliance. It will also cover the changes in how analytical methods will be added to SW-846.
