EPA’s Key Management Challenges for Fiscal Year 2008, July 2, 2008: “EPA needs to periodically assess threats to human health and the environment across media to ensure that resources and priorities focus on the highest risks, regardless of the source. Presently, EPA’s strategic goals stress reducing risks to human health and the environment from distinct sources – such as air pollution, water pollution, and hazardous releases on land. This is feasible because EPA invests in science to enhance its understanding of health and ecological implications, enabling it to identify and develop risk assessment methodologies. Risk assessors can use these methodologies to evaluate the adequacy of current exposure assessment approaches.2 Risks are assessed within each of the Agency’s strategic goals – for example, for air pollution effects, radiation, waste treatment, Superfund cleanups, etc. However, the Agency does not assess threats to human health and the environment across media to ensure EPA’s actions are designed to reduce total risk in the most efficient manner.”
