EPA's mission is to protect human health and to safeguard the natural environment—air, water, and land—upon which life depends.

Tools and Approaches Will
Continue to be based on sound science and utilize available data
Be legally defensible under statutory mandates
Be based on methodologies that are as consistent and practical as possible
Be implementable at the federal and state level
Be developed as quickly as possible, and Reflect stakeholder input and comments
What we hope to achieveWhat we hope to achieve
Provide a common basis for the characterization of aquatic effects of pesticides under the CWA and FIFRA resulting in effects assessments that are consistent with both statues.
The community benchmarks generated for protection of aquatic wildlife and plants may be adopted: by states for standards, permitting, 303(d) for assessment of monitoring data by OPP in addition to other benchmarks in risk assessment.
The tools developed for generating toxicity values can be used to develop species sensitivity distributions for characterizing
interspecies variability for bridging data to characterize uncertainty
Methodologies are identified for using aquatic plant data in deriving community-level benchmarks.
