Appendix H <br />Aluminum and Magnesium Phosphide for Burrowing Rodent <br />Control Recommended Permit Conditions <br />Background In April 2010, the U.S. Environmental Protection Agency (U.S. EPA) <br />requested that aluminum and magnesium phosphide products for burrowing <br />rodent control be labeled with additional restrictions to protect human health. <br />This included prohibiting use around residential areas and increasing the <br />distance from 15 feet to 100 feet from the application to a building that is, or <br />may be occupied by, humans and/or animals, especially residences. <br />Subsequently, in March 2012, U.S. EPA allowed registrants to amend label <br />and labeling (Applicator's Manual), reinstating outdoor use around residential <br />and other properties, but prohibited use within 100 feet of any building where <br />humans and/or domestic animals do or may reside. <br />Recommended Because there still may be aluminum and magnesium phosphide products <br />permit with older labeling lacking the U.S EPA restrictions in the channels of trade, <br />conditions the following permit restrictions are recommended to ensure that the more <br />restrictive use requirements are applied to all aluminum or magnesium <br />phosphide products for burrowing rodent control. <br />Aluminum and magnesium phosphide must only be used out-of-doors for <br />control of burrowing pests on agricultural areas, orchards, non -crop <br />areas, pastures, rangeland, golf courses, athletic fields, airports, <br />cemeteries, rights -of -ways, earthen dams, parks and recreational areas, <br />other non-residential institutional or industrial sites and on residential or <br />other commercial properties. <br />2. Use of aluminum and magnesium phosphide is prohibited within 100 feet <br />of any building where humans and/or domestic animals do or may reside <br />on single and/or multi -family residential properties and nursing homes, <br />schools (except athletic fields [application is allowed less than 100 feet to <br />an occupied structure]), daycare facilities, hospitals and other commercial <br />buildings that are regularly occupied. <br />Continued on next page <br />H-1 <br />(Rev. 12-14) <br />
