Protecting Endangered
Species
Interim Measures
Williams County, North Dakota
The information in this pamphlet is
similar to what the U.S. Environmental
Protection Agency (EPA) expects to
distribute once our Endangered Species
Protection Program is in effect. The
limitations on pesticide use are not law at
this time, but are being provided now for
your use in voluntarily protecting
endangered and threatened species from
harm due to pesticide use. We encourage
you to use this information. We also
welcome your comments.
The Endangered Species Act is intended
to protect and promote recovery of animals
ana plants that are in danger of becoming
extinct due to the activities of people.
Under the Act, EPA must ensure that use
of pesticides it registers will not result in
harm to the species listed as endangered or
threatened by the U.S. Fish and Wildlife
Service, or to habitat critical to those
species' survival. To accomplish this, the
EPA expects to implement program
requirements beginning in 1991. This
program will protect endangered and
threatened species from harm due to
pesticide use.
EPA requests your comments regarding
the information presented in this
publication. Please drop us a line to let us
know whether the information is clear and
correct. Also tell us to what extent
following the recommended measures
would affect your typical pesticide use or
productivity. This information will be
considered by EPA during the final stages
of program development.

About This Publication
This publication contains a County Map
showing the area within the county where
pesticide use should be limited to protect
fasted species. These areas are identified on
the map by a shaded pattern. Each shaded
pattern corresponds to a species in need of
protection.
The Shading Key shows the name of the
species that each shaded pattern represents
and describes the shaded area. The area
may be described in terms of Township,
Range, and Section or by giving details
about the habitat of the species.
The first column of the "Table of Pesticide
Active Ingredients" lists the active
ingredients for which there should be
limitations on use to protect certain species.
The next columns are headed by the shaded
pattern of the species with Codes listed
underneath them.
The Code indicates the specific limitation
that is necessary to protect the species. The
section titled Limitations on Pesticide Use
explains the code.
Does This Information Apply To
You?
To determine whether this information
applies to your use of a pesticide, review
the questions below. The information
applies only if you answer "yes" to both
questions;:
• Do you intend to use pesticides within
the shaded area on the county map?
• Are any of the ingredients listed on the
front panel of your pesticide product label
named in the "Table of Pesticide Active
Ingredients"?
If you answer "yes" to both questions,
you should follow the instructions on "How
to Use This Information" to determine if
you should limit use of the pesticide to help
protect listed species.
If you answer "no" to either question,
you should follow the usage directions on
the pesticide product label.

How To Use This Information
Table Of Pesticide Active Ingredients
1) On the county map, find the specific shading patterns
that cover the area where you will apply pesticides.
2) Read the shading key for those patterns to identify
the specific area involved.
3) In the "Table of Pesticide Active Ingredients," locate
the active ingredients in the pesticide you intend
to apply.
4) Locate the code to the right of the active ingredient
name and under the shading patterns that apply
to you.
5) When using the pesticide, you should follow the
limitations indicated for those codes described under
"Limitations on Pesticide Use."
6) If you are applying more than one listed active
ingredient or applying a listed active ingredient in
an area with more than one shaded pattern (species),
multiple'codes may apply. If so, you should follow
the most restrictive limitation.

Reducing Runoff and Drift
Careful use of pesticides can diminish harm to the environment and reduce exposure of endangered and
threatened species to pesticides. Using pesticide runoff and drift measures may be helpful in keeping more
of the applied pesticide on the field and may also lower your costs of pesticides.
Runoff
Where possible, use methods which reduce soil erosion, such as limited till and contour plowing; these
methods also reduce pesticide runoff.
Where feasible, use application techniques such as T banding and in-furrow techniques, which incorporate
the pesticide into the soil.
Pesticides with ground water warning labels are more likely to enter ground and surface water than those
without such warnings. When possible, use a pesticide that does not contain a ground water warning label.
Keep informed about changing weather conditions, and try to avoid pesticide application when heavy
rainfall is expected.
Drift
Wind direction, speed, and evaporation are important factors in reducing drift. Most importantly,
pesticides should be applied when the wind direction is away from areas of concern; try to avoid applica-
tion during periods of high winds. Avoiding applications during the hottest part of the day, when evapora-
tion is highest, will further reduce drift.
When high winds and excessive evaporation are not present, a drift retardant may be useful for aerial
applications.
Using the largest droplet size compatible with the pesticide coverage will reduce drift. Typically, higher
spray volumes will also result hi less drift.
