Interim Measures

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 and
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 1994. 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
let us know whether the information is clear and
correct. Also tell us to what extent following the
recommended measures would affect you 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 listed
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 often
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 pf 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 Thijf 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 or
near 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 pf Pesticide Active
Ingredients"? -
Jf you answer "yes" to both questions, you
should follow the instructipns on "How to Use
This Information" to determinp if you shpuldi
limit use of the pesticide to help protect listed
species.
If you answer "np" to either question, you
should follow the usage directions on the
pesticide prisduct label.
-------
How To Use This Information
1) On the county map, find the specific shading pattern(s)
in or near the area where you intend to apply pesticides.
2) Read the descriptor under the Shading Key for the
pattern(s) to identify the specific area involved.
3) In the "Table of Pesticide Active Ingredients," locate the
active ingredient in the pesticide you intend to apply.
4) Locate the code to the right of the active ingredient name
and under the shading pattern(s) that apply to you.
5) When using the pesticide, find the code(s) described
under "Limitations on Pesticide Use" and follow the
limitation given.
6) If you are applying more than one listed active ingredient
or applying a listed active ingredient in an area with
more than one shading pattern (species), multiple codes
may apply. If so, you should follow the most restrictive
limitation.
7) Read the information on Reducing Runoff and Drift in
this pamphlet.

Reducing Runoff and Drift
Careful use of pesticides can cjiminish harm tp 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 alsp 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 arid 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 dpes not contain a ground water warning label.
Keep Informed about changing weather cpnditipns, and try tP avoid pesticide application when heavy rainfall is expected.
Drift
Wind direcp'pn, speed, and evappratipn are important factprs in reducing drift. Most importantly, pesticides should be
applied when the wind direptipft is away from areas pf cpncern; try tp avoid applicatipn during periods of high winds.
Avoiding applications during the hottest part of the day, when evaporation 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 cpverage will reduce drift. Typically, higher spray vplumes
will alsp result in less drift.
