                  Protecting   Endangered
                 Species
                 Interim  Measures
                 Pima  County, Arizona
                     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 1993. 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 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

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 Held 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 in less drift.
