Technical Memorandum
Date: April 3, 2009
To: Deschutes County
From: Ted Gresh and John Runyon, ICF Jones & Stokes; Joanne Richter, WPN
cc: Central Oregon Intergovernmental Council (COIC)
Subject: Deschutes County ESA Risk Assessment Evaluation
The cities and counties of Central Oregon (the jurisdictions) are evaluating whether current local
government policies and practices are sufficiently protective of steelhead and their habitat, listed
and protected under the federal Endangered Species Act (ESA). Specifically, the jurisdictions aim
to avoid the “take” of re-introduced steelhead, potential ESA enforcement actions, or third-party
lawsuits.
ICF Jones & Stokes has developed a Risk Assessment Framework to systematically evaluate
jurisdictions’ management policies and practices for their potential risks to listed steelhead. The
following tables and text outline our preliminary evaluation of your jurisdiction’s codes, policies,
and practices. The evaluation was developed from a review of relevant documents and staff
interviews.
The evaluation is organized within the Risk Assessment Framework and focuses four areas:
1) land use, 2) stormwater management, 3) pest management, and 4) routine road maintenance.
This evaluation will be incorporated in the final report as an appendix and will provide the
basis for summarizing your jurisdiction’s activities and developing recommendations.
As outlined in the Risk Assessment Framework, surface and groundwater withdrawals and
wastewater discharge will be summarized separately for each jurisdiction (when it applies) and
not evaluated for their potential risk to steelhead.
Please review the attached evaluation. Your comments should focus on correcting any incorrect
descriptions of your codes, policies, or practices. Where appropriate, please note where we are
missing descriptions of relevant activities.

Technical Memorandum
List of 27 Pesticides/herbicides that require no spray buffers to protect threatened and endangered Pacific
salmon, November 5, 2007.
azinphos-methyl Chlorpyrifos* fenbutatin-oxide naled
bensulide Diazinon* lindane phorate
bromoxynil dimethoate Malathion* prometryn
captan disulfoton methidathion propargite
carbaryl diuron methomyl triclopyr BEE
carbofuran ethoprop methyl parathion trifluralin
chlorothalonil fenamiphos Metolachlor
* NMFS issued a Biological Opinion for Chlorpyrifos, Diazinon, and Malathion in November 2008.
No Spray buffers are required for all pesticides that the Environmental Protection Agency (EPA) determined are “likely to adversely affect”
threatened and endangered Pacific salmon and steelhead.
In January 2001, 38 pesticides required no spray buffers because EPA had not yet determined which pesticides were likely to adversely affect
salmon and steelhead. Since then EPA has narrowed the list to 27 pesticides.
Routine Road Maintenance
Since the County relies on the ODOT Routine Road Maintenance Manual to conduct road
maintenance procedures, this risk assessment does not focus on how the County conducts specific
road maintenance activities, but rather makes recommendation to the County to ensure adequate
documentation exists on how the County conducts road maintenance in the event an incident
should occur that impacts County surface waters. These recommendations are based on ODOT’s
training programs and procedures that are part of their maintenance program and describe how
they implement their Routine Maintenance Program.
In order to ensure that the County is committed to conducting road maintenance activities in
accordance with the ODOT manual the County should consider the adoption and utilization of the
following documents:
1. A formal letter of commitment to conduct their road maintenance procedures in
accordance with the ODOT manual.
2. Procedures for the documentation and reporting of their maintenance activities along
roads that cross or are adjacent to surface waters.
3. Adoption of a required training program for routine maintenance personnel. The County
could utilize existing ODOT trainings for road maintenance personnel that include:
a) Maintenance Academy: for new employees, includes presentation of the
Manual and other environmental issues
b) Incident Responder classes, including “Plug and Patch” training on
maintenance responsibilities for spills
c) Basic Hazardous Materials Awareness
d) Erosion and Sediment Control training

Technical Memorandum
e) Technology Transfer (T2) programs including Roads Scholars that has
environmental sessions including vegetation management, erosion control,
etc.
4. Create and adopt Resource Maps and Restricted Activity Zone Maps:
a) Resource Maps should provide the general proximity and areas of probability
for natural resources adjacent to County roads.
b) The Restricted Activity Zone Maps define the road maintenance activities and
relate the identified resource (wetlands, riparian area, etc.) to each
maintenance activity.
c) Maintenance personnel would review each map while planning work to
determining appropriate BMPs for each activity.
d) Road Masters should hold Resource and Restricted Activity Zone map
coordination meetings to make sure personnel understand where resources are
located and what BMPs are to be employed.
By adopting these documents and programs the County would create a framework for the Public
Works Department to follow and would inform the public and state and federal regulatory
agencies of their commitment to ensure the ODOT manual is implemented consistently and
appropriately.
