The P2 Programs data provided in response to the OMB PART assessment generally addressed the PART questions and supported the moderately effective rating received. However, we noted several weaknesses: The P2 Programs Fiscal Year 2006 PART performance measures were not designed to report on the programs impacts to human health and the environment. P2 Program managers believed that reductions in discharges and emissions of pollutants represent the best measures that can be supported by data obtainable on a program-wide basis and acknowledge that additional outcome measures are needed to assess impacts on human health and the environment associated with hazardous materials reductions. The P2 Programs verification and validation procedures did not ensure the accuracy of performance data. P2 program managers had no assurance that performance results data obtained from voluntary partnerships with industry and other organizations were accurate. The Programs Fiscal Year 2006 performance results were not reported consistently and contain inaccuracies. Strengthening data controls would provide P2 managers with improved program performance data. While the P2 Program has completed several interim PART follow-up actions, some of its actions to address its program improvement plan have been slow. In addition, the plan did not address all deficiencies identified in the PART assessment.
