Section 1 contains the regulatory authority and framework for deregistration/tolerance reassessment. Section II provides a profile of the use and usage of the chemical. Section III gives an overview of the revised human health and environmental effects risk assessments. Section IV presents the Agency's reregistration eligibility and risk management decisions. Section V identifies label changes necessary to implement the risk mitigation measures. Finally, among the Appendices is a description of the revised use patterns, generic and product-specific Data Call-In (DCI) information.
