Comment submitted by Martin Tiemann, Intervet Inc.

The proposed rule proposes reduced tolerances for cattle and hogs without having shown that there is a toxicological concern. Since existing tolerances meet the standard of "reasonable certainty of no harm", Intervet requests that the tolerances for cattle and hogs remain unchanged. The proposed rule states: "Based on the available data following dermal treatment and a 3-day pre-slaughter interval on cattle with amitraz......Based on available data following dermal treatment of swine with amitraz which show.....". This statement incorrect since there is no pre-slaughter interval in cattle, however there is a 3 day pre-slaughter period in swine. Intervet kindly requests that the final rule be amended to reflect what is approved by EPA.
