II. What Guidance Does this PR Notice Provide?

This final PR Notice provides guidance pertaining to applications for registration of antimicrobial products that would make labeling claims to “inactivate Bacillus anthracis (anthrax) spores” (hereafter referred to as “anthrax-related products”). This guidance should help the United States be prepared to respond to incidents involving anthrax spores by assuring that anthrax-related products are registered, that they bear appropriate labeling, and that they are effective when used as directed. In addition, this guidance will help protect public health from the potential risks of anthrax spores by limiting the use of anthrax-related products to those who are properly trained and determined to be competent in their use.

In summary, this PR notice specifies that in order for a product to qualify for a claim of inactivating anthrax spores, an anthrax-related product should be: (a) supported by specific sporicidal efficacy studies that are acceptable to EPA and (b) subject to specific terms and conditions of registration that limit the use of these products to certain persons. Prospective applicants are encouraged to follow the guidance in this notice and consult with EPA prior to applying for registration or amendment of a product when seeking such a claim.

In October 2001, when several letters containing Bacillus anthracis (anthrax) spores were introduced into the U.S. Postal Service mail system, no antimicrobial products were specifically registered for inactivating the spores of this particular pathogen. Since that time, EPA/OPP has developed guidance on the terms and conditions of registration for the labeling of these products that will limit their use to certain persons, as described below. In addition, the EPA/OPP has developed guidance on laboratory efficacy test methods for demonstrating the effectiveness of antimicrobial products for inactivating anthrax spores on inanimate surfaces. Such efficacy testing guidance will be issued separately from this PR Notice. It is EPA's intent that registrants will follow the efficacy testing guidance and this PR Notice when applying for registration of anthrax-related products, and that such products, when registered, will be made available to trained and competent civilian and military personnel who respond to incidents involving anthrax spores.

The information collection activities associated with the activities described in this PR Notice are already approved by the Office of Management and Budget (OMB) under the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq. The corresponding Information Collection Request (ICR) document for the training of pesticide applicators has been assigned EPA ICR number 0155.09 and is approved under OMB control number 2070-0029. The ICR document for the pesticide application process has been assigned EPA ICR number 0277.13, and is approved under OMB control number 2070-0060. The total estimated respondent paperwork burden associated with the training and certification of a pesticide applicator is an annual average of 3.1 burden hours. The annual average reporting and recordkeeping burden for a registration applicant respondent is estimated to range from 14 hours to 646 hours, depending upon the type of activity. For “Type A” activities, which include new active ingredients and new uses, the estimated annual applicant burden average is 194 hours per application. For “Type B” activities, which include amendments and notifications, the estimated annual applicant burden average is 14 hours per application. The respondent burden estimate for “Type C” reduced risk products is an average of 646 hours per product. A copy of the most recent version of EPA ICR #0155.09 is available under Docket ID No. EPA-HQ-OPP-2003-0357, and a copy of the most recent version of EPA ICR #0277.13 is available under Docket ID No. EPA-HQ-OPP-2004-0419.

III. Do PR Notices Contain Binding Requirements?

The PR Notice discussed in this notice is intended to provide general guidance to pesticide applicants and registrants. While the requirements in the statutes and Agency regulations are binding on EPA, registrants, and applicants, this PR Notice is not binding on either EPA or any outside parties, and EPA may depart from the guidance where circumstances warrant and without prior notice. Likewise, pesticide applicants and registrants may assert that the guidance is not appropriate generally or not applicable to a specific pesticide or situation. Pesticide applicants and registrants may propose alternatives to the recommendations described in the PR Notice, and the Agency will assess them for appropriateness on a case-by-case basis and will respond in writing.
