Final Comprehensive Conservation Plan - U.S. Fish and Wildlife ...

Hakalau Forest National Wildlife Refuge
Comprehensive Conservation Plan
(http://www.fs.fed.us/r6/invasiveplant-eis/Risk-Assessments/Herbicides-Analyzed-InvPlant-
EIS.htm) and Bureau of Land Management (http://www.blm.gov/wo/st/en/prog/more/veg_eis.html).
These risk assessments and associated documentation also are available in total with the
administrative record for the Final Environmental Impact Statement entitled Pacific Northwest
Region Invasive Plant Program – Preventing and Managing Invasive Plants (US Forest Service
2005) and Vegetation Treatments Using Herbicides on Bureau of Land Management Lands in 17
Western States Programmatic EIS (PEIS) (Bureau of Land Management 2007). In accordance with
43 CRF 46.120(d), use of existing NEPA documents by supplementing, tiering to, incorporating by
reference, or adopting previous NEPA environmental analyses would avoid redundancy and
unnecessary paperwork.
As a basis for completing “Chemical Profiles” for approving or disapproving refuge PUPs,
ecological risk assessments for the following herbicide and adjuvant uses prepared by the US Forest
Service would be incorporated by reference:
• 2,4-D;
• Chlorosulfuron;
• Clopyralid;
• Dicamba;
• Glyphosate;
• Imazapic;
• Imazapyr;
• Metsulfuron methyl;
• Picloram;
• Sethoxydim;
• Sulfometuron methyl;
• Triclopyr; and
• Nonylphenol polyethylate (NPE) based surfactants.
As a basis for completing “Chemical Profiles” for approving or disapproving refuge PUPs,
ecological risk assessments for the following herbicide uses as well as evaluation of risks associated
with pesticide degradates and adjuvants prepared by the Bureau of Land Management would be
incorporated by reference:
• Bromacil;
• Chlorsulfuron;
• Diflufenzopyr;
• Diquat;
• Diuron;
• Fluridone;
• Imazapic;
• Overdrive (diflufenzopyr and dicamba);
• Sulfometuron methyl;
• Tebuthiuron;
• Pesticide degradates and adjuvants (Appendix D – Evaluation of risks from degradates,
polyoxyethylene-amine (POEA) and R-11, and endocrine disrupting chemicals).
