EPA is amending the 1992 Worker Protection Standard (WPS) by establishing the length of time for which decontamination supplies are required at 7 days following the expiration of pesticide restricted- entry intervals (REIs) of 4 hours or less. Pesticides with REIs of 4 hours or less have passed an EPA risk screening process because of their low acute toxicity, an absence of evidence of worker poisonings after the REI, and a lack of other concerns about toxicity. The decontamination requirements for all other pesticides are not affected by this amendment.
