US Environmental Protection Agency Office of Pesticide Programs Reregistration Eligibility Decision for Formetanate Hydrochloride When EPA concluded the N-methyl carbamate cumulative risk assessment in September 2007, all tolerance reassessment and reregistration eligibility decisions for individual N-methyl carbamate pesticides were considered complete. N-methyl carbamate Interim Reregistration Eligibility Decisions (IREDs), therefore, are considered completed REDs. Combined PDF document consists of the following: • Completion of the Tolerance Reassessment and Final Reregistration Eligibility Decisions for the N-methyl Carbamate Pesticides (September 24, 2007) • Formetanate Hydrochloride IRED United States Prevention, Pesticides Environmental Protection and Toxic Substances March 2006 Agency (7508C) EPA 738-R-06-015 Interim Reregistration Eligibility Decision for Formetanate Hydrochloride Interim Reregistration Eligibility Decision (IRED) Document for Formetanate Hydrochloride Case Number 0091 Approved by: Date: Debra Edwards, Ph.
