RE: 2009 Multnomah County Pesticide Use Plan 

Dear Mr. Wirth: 

The Oregon Department of Fish and Wildlife has completed review ofthe Multnomah County 

(County) 2009 Pesticide Use Plan (PUP) in accordance with ORS 452.140. 

ODFW compliments the County on providing detailed information on vector control operations, 

including maintaining and protecting the environment. 

Based on the information you supplied, your plan is approved, which includes identification of 

sensitive fish and wildlife areas and critical habitat for federally listed threatened fish species and 

mosquito management within and around these areas. 

In addition, the following are required as part ofthe PUP approval: 

•	 Meet annually with ODFW staffto identify any additional sensitive habitats and protections 

needed, especially for native turtles. Sensitive turtle nesting areas may need seasonal 

protections, possibly including no mosquito treatments unless disease carrying mosquitoes 

are identified at the specific location. 

•	 As identified in MCVNC's 2009 document, Description o/the Vector Control District, when 

applying adulticides to sensitive areas, sufficient buffers listed must be maintained to ensure 

that pesticides do not drift into sensitive areas. 

•	 Ifmosquito control is needed in any sensitive areas as a result of disease detection or 

outbreak, ODFW prefers use ofmicrobial larvicides. 

•	 As indicated in your PUP, no pesticide applications may be made to Sauvie Island Wildlife 

Area (WA) without first consulting with Mark Nebeker, manager of the WA (Tel. 503-621­

3488). In the event of an emergency as the result of a mosquito-borne disease outbreak and 

Mr. Nebeker is unavailable, contact should be made in the following order: ODFW 

Watershed Manager, Jeff Boechler (Tel. (971) 673-6005), Chris Wheaton, Regional Director 

(Tel. 971-673-6007), Eric Rickerson, Program Manager for Wildlife Habitat (Tel. 503-947­

6082), or Jill Zarnowitz, ODFW Vector Control Plan Coordinator (Tel. 503-947-6092).

•	 We note that the County stocks Gambusia affinis (western mosquitofish) and that a fish 

transportation pennit has been obtained. Please provide a link to the document below or post 

it on MCVNC's website to ensure the public understands that gambusia must be used only in 

aquaria (document attached):

health. If you have any questions, please call Jill Zamowitz or Mischa Connine (tel. 503-621­
