Planning and Standard Operating Procedures for the Use of Rotenone in Fish Management: Rotenone SOP Manual, 2nd Edition

4 Standard Operating Procedures


The techniques for using rotenone are outlined in the following 16 SOPs. The information contained in each SOP in the Rotenone SOP Manual generally follows the order (1) title, (2) purpose, and (3) procedure. SOPs may be revised or new SOPs may be added and approved by the EPA in the future. Applicators should check the AFS website frequently for changes. The reference to the revision is listed as SOP #.* (# is SOP number and * is revision number). Readers can submit comments to the AFS webpage.

The words “must,” “should,” “may,” “can,” and “might” have very specific meanings in these SOPs:

“Must” is used to express an absolute (mandatory) requirement, that is, to state that the guidelines are designed to satisfy the specified condition. “Must” is only used in conjunction with factors that directly relate to the legality or acceptability of specific recommendations (i.e., a requirement on the label of a pesticide product).

“Should” is used to state that the specified condition is recommended (advisory) and ought to be met, if possible. Terms such as “is desirable,” “is often desirable,” and “might be desirable” are used in connection with less important factors.

“May” is used to mean “is (are) allowed to.”

“Can” is used to mean “is (are) able to.”

“Might” is used to mean “could possibly.” “Might” is never used as a synonym for either “may” or “can.”
