C. What Action Is the Agency Taking?

EPA is announcing that American Cyanamid Company, P.O. Box 400, Princeton, NJ 08543-0400 has withdrawn its application to register a pesticide containing chlorfenapyr for use on cotton as provided for in section 3(c)(7)(C) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended by the Food Quality Protection Act of 1996 (FQPA). Chlorfenapyr is an active ingredient not included in any previously registered pesticide product. Chlorfenapyr has been proposed for many uses on several pests. This withdrawal notice is applicable to the products PIRATE and ALERT for use on cotton.

EPA issued a notice in the Federal Register of December 2, 1998 (63 FR 66534) (FRL-6046-6), which announced American Cyanamid's submission of an application to register a pesticide product (EPA File Symbols 241-GAT and 241-GAI) containing an active ingredient, 4-bromo-2-(4-chlorophenyl)-1-(ethoxymethyl)-5-(trifluoromethyl)-1-pyrrole-3-carbonitrile (chlorfenapyr), not included in any previously registered pesticide product. The application was for an insecticide/miticide for use on cotton.

On January 20, 1999 (64 FR 3091) (FRL-6489-2), EPA published in the Federal Register a Notice of Availability of Risk/Benefit Assessments. These assessments were made available for public comment in the docket and at​opprd001/​chlorfenapyr/​toc.htm. The Agency received approximately 400 public comments in the docket in response to the notice.

In addition, the Office of Pesticide Programs submitted EPA's and American Cyanamid's risk assessments to peer review by the Federal Insecticide, Fungicide, and Rodenticide Act (“FIFRA”) Scientific Advisory Panel (“SAP”). The SAP met twice to review the assessments. The SAP reports are available at:​oscpmont/​sap/​1999/​july/​finlrpt3.pdf​oscpmont/​sap/​1999/​september/​finalrpt.pdf.

The Agency also had extensive discussions with the United States Fish and Wildlife Service (FWS). The comments received by the FWS were taken into consideration in EPA's registration assessment.

On March 13, 2000, Susan H. Wayland, Acting Assistant Administrator for the Office of Prevention, Pesticides and Toxic Substances, signed a decision memorandum for the denial of chlorfenapyr use on cotton. Copies of the decision memorandum are available in the docket. American Cyanamid has since decided to withdraw its application for registration.
