The Improving Science in Chemical Assessments Act aims to enhance the assessment of chemical toxicity by directing the Environmental Protection Agency (EPA) to conduct these assessments through its various program offices rather than a single program. This change is intended to ensure that the evaluations are more aligned with the specific needs and priorities of different areas within the EPA. One of the key provisions of the Act is that it requires the EPA to coordinate its research and development efforts with the needs of its program offices.
