2. Background

   1. What Guidance Does the PR-Notice on Labeling Provide?

      In the PR-Notice, EPA provides registrants with guidance for new labeling statements for controlling pesticide spray and dust drift. These statements are intended for agricultural, industrial, home, lawn, garden, and certain other outdoor use pesticide products applied by aerial, ground rig, orchard airblast, chemigation, and handheld equipment. These proposed statements are based on EPA's policy on drift, which is articulated in the PR-Notice, studies submitted by registrants, other studies in the open scientific literature, and communications with applicators, registrants, academicians, and other Federal, state, and tribal government agencies. The Agency generally considers the label statements to be generic statements and representative of drift mitigation measures that are practical and effective to reduce drift under most application situations.

      The Agency acknowledges, however, that this labeling guidance may not be appropriate for all products and that for certain products there may be appropriate alternatives to the wording of these statements. EPA will consider other wording proposed by registrants for their products. This notice is not binding on either EPA or pesticide registrants, and EPA may depart from the guidance where circumstances warrant and without prior notice. Likewise, pesticide registrants may always assert that the guidance is not appropriate generally or not applicable to a specific pesticide or situation. The intention of these new statements is to provide registrants and applicators with improved and more consistent directions for controlling drift from application sites and assuring protection to human health and the environment. This notice also provides the Agency's position on drift, definitions of the terms ``spray (or dust) drift'' and ``no-spray zone,'' rationale for the label statements, and a plan for what registrants should do.

   2. What Issues/Questions Should you Consider?

      Those who wish to comment are free to raise any issue, but the following questions are of particular interest to the Agency, and comments on them are invited.

      1. The Agency requests comments on the proposed labeling statements, specifically in four areas described in this and the following three paragraphs. In the proposed guidance for labeling statements, the first sentence of the proposed labeling is a prohibition against allowing drift from the application site to contact people and the specified sensitive areas. The Agency is interested in comments about whether this labeling statement provides a definitive and enforceable requirement or expectation to applicators for protecting human health and the environment from drift.

      2. The Agency is interested in comments regarding the inclusion of specific application conditions in the labeling statements, the selection of the specific application conditions as key measures to control drift, and their enforceability and practicality to be followed under many different application scenarios. The proposed labeling statements include specific limitations for application conditions, including maximum wind speed, application height, and nozzle placement, which are key variables in affecting the quantity and distance or deposition of drift. The proposed specific limits are based on the available studies on drift, particularly those dealing with cause and effect. Placing a limitation on these variables is a means to control drift and reduce pesticide exposures and associated risks to human health and the environment.

      3. The Agency asks for comment on the content of the proposed labeling statement for home and garden products. According to information on drift incidents provided by States, use of these products result in a significant portion of the total number of all reported drift incidents. The Agency is mindful that any wording for these products would need to be simpler than for other types of products, such as agricultural products, which are likely to be applied by trained applicators.

      4. Because higher risk pesticides may lead to the need for no-spray zones for additional risk reduction, the Agency is proposing a no-spray zone labeling statement that generally would be used for those pesticide products. The Agency is interested in comments on its proposal for no-spray zones and the proposed labeling statement for no- spray zones.

   3. Summary of the Agency's Position on Drift

      The Agency has the responsibility to ensure that the use of pesticides will not cause unreasonable adverse effects to human health and the environment. Those involved in pesticide application decisions have an important responsibility to protect people, domestic animals, wildlife, and the environment from pesticide exposures and potential harm from drift. States, tribes, and EPA have responsibilities to carry out enforcement to ensure compliance with pesticide use requirements.

      EPA's position on pesticide drift is that applicators must not allow spray or dust drift to contact people, animals, and certain sensitive sites, including structures people occupy at any time, and the associated property, parks and recreation areas, nontarget crops, aquatic, wetland areas, woodlands, pastures, and rangelands. The Agency believes this is prudent public policy. It sets high but appropriate standards for applicators to protect people and the environment. Applicators must consider and use necessary application practices and measures required by states or tribes in addition to mandatory drift control measures that are stated on product labels.

      EPA realizes this position sets high but appropriate standards for applicators to protect people and the environment. However, the Agency believes that this policy will not have an undue impact on agriculture or other uses of pesticides. Rather, this policy

      [[Page 44143]]

      and new labeling will clarify expectations of applicators and set definitive standards for application practices. The Agency also believes that in addition to improved labeling a very important component for controlling drift is training and education of applicators and others involved in pesticide application decisions about the causes and consequences of drift, control methods, and legal requirements.

   4. Other Options EPA Considered for Labeling

      EPA considered a variety of other options for label statements for spray drift mitigation, some of which were offered by stakeholders. These other labeling options and the Agency's reactions are discussed below. The Agency welcomes comment on these other options.

      Label Statement Option-``Do not Allow Spray Drift''

      This option, which EPA has required on some product labels, oversimplifies and conflicts with the Agency's conclusions of the supporting scientific data that some de minimus degree of drift will occur as part of nearly all pesticide applications. Nevertheless, recognizing the inadequacies of this statement and its appearance on numerous product labels for many years, we believe that it has been effectively and practically enforced by EPA, states, and tribes. Enforcement authorities have used their discretion to pursue violations based on their evaluation of those cases where there may have existed the potential for an effect or concern for exposures and risks to off- target people, animals, plants, and the environment.

      Label Statement Option-``Do not Allow Drift to Cause Adverse Effects''

      EPA believes this statement is problematic from an enforcement perspective because the burden of proof must be shifted from the simple fact of drift to the ``effect'' of drift, which is less compatible with the nature of evidence gathered in field investigations. This would require the determination of the definition of ``adverse effects'' under numerous circumstances on a case-by-case basis.

      An additional problem with this label statement is it suggests to applicators that drift is acceptable unless someone recognizes and reports effects and appropriate authorities rule the effects are ``adverse.''

      Label Statement Option-``Minimize Drift to Sensitive Areas. If Drift Occurs and Causes Environmental and Economic Effects, Enforcement Action May be Taken''

      ``Minimize drift'' suggests the Agency finds certain levels of off- target drift acceptable, contrary to EPA's policy as discussed above. Further, Agency enforcement authorities believe this statement compromises their responsibilities by jeopardizing their ability to take enforcement action when necessary. The second proposed statement also causes concern. Under this label statement EPA, states, and tribes would have to prove drift as well as both environmental and economic effects before taking further action.

      Since there is no label minimization standard, this statement essentially provides tacit permission to allow drift to occur at certain levels, presumably at levels up to those that do not cause ``environmental and economic effects.'' If certain levels of drift are permissible, a statement that off-target drift may result in enforcement action is nonsensical.
