version 1.2.3. T-REX input variables would include the following: max application rate (acid basis
[see above]) and pesticide half-life (days) in soil to estimate the initial, maximum pesticide residue
concentration on general food items for terrestrial vertebrate species in short (LOCs, then a PUP would only be approved with additional BMPs specifically to minimize
exposure (ecological risk) to bird, mammal, and/or fish species. One or more BMPs such as the
following would be included in the Specific Best Management Practices (BMPs) section to reduce
potential risk to non-listed or listed species:
• Lower application rate and/or fewer number of applications so RQs≤LOCs
• For aquatic assessments (fish) associated with cropland/facilities maintenance, increase the
buffer distance beyond 25 feet so RQs≤LOCs.
Justification for Use: Service personnel would describe the reason for using the pesticide based
control of specific pests or groups of pests. In most cases, the pesticide label will provide the
appropriate information regarding control of pests to describe in the section.
Specific Best Management Practices (BMPs): Service personnel would record specific BMPs
necessary to minimize or eliminate potential effects to non-target species and/or degradation of
environmental quality from drift, surface runoff, or leaching. These BMPs would be based upon
scientific information documented in previous data fields of a Chemical Profile. Where necessary
and feasible, these specific practices would be included in PUPs as a basis for approval.
If there are no specific BMPs that are appropriate, then Service personnel would describe why the
potential effects to refuge resources and/or degradation of environmental quality is outweighed by
the overall resource benefit(s) from the proposed pesticide use in the BMP section of the PUP. See
Section 4.0 of this document for a complete list of BMPs associated with mixing and applying
pesticides appropriate for all PUPs with ground-based treatments that would be additive to any
necessary, chemical-specific BMPs.
References: Service personnel would record scientific resources used to provide data/information
for a chemical profile. Use the number sequence to uniquely reference data in a chemical profile.
The following on-line data resources are readily available for toxicological endpoint and
environmental fate data for pesticides:
