# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Notice of availability.

# SUMMARY:

The Agency is announcing the availability of and seeking public comment on a draft Pesticide Registration Notice (PR Notice) entitled “Use of Antimicrobial Pesticide Products in Heating, Ventilation, Air Conditioning and Refrigeration Systems.”   PR Notices are issued by the Office of Pesticide Programs (OPP) to inform pesticide registrants and other interested persons about important policies, procedures, and registration related decisions, and serve to provide guidance to pesticide registrants and OPP personnel.  This particular draft PR Notice would, once final, provide guidance to the registrants concerning EPA-registered sanitizer, disinfectant and other antimicrobial products whose labels bear general directions for use on or incorporation within hard, non-porous or porous surfaces, but which are not specifically registered for treatment of Heating, Ventilation, Air Conditioning and Refrigeration Systems (HVAC&R).

Comments must be received on or before November 21, 2006.

                    1.                     *Docket.*                     EPA has established a docket for this action under docket identification (ID) number EPA-HQ-OPPT-2006-0351.  Publicly available docket materials are available either in the electronic docket at                     *http://www.regulations.gov*, or, if only available in hard copy, at the Office of Pesticide Programs (OPP) Regulatory Public Docket in Rm.

## II.  What Guidance Does this PR Notice Provide?

The EPA is concerned that sanitizer, disinfectant and other antimicrobial products are being used to treat surfaces of HVAC&R systems, including but not limited to use as a part of an air duct cleaning program.  When initially registered, these products were approved for use on hard surfaces such as countertops, but air ducts were not intended to be included in the broad hard surface category.  EPA is concerned that data demonstrating efficacy when used in air ducts have not been submitted for review by the Agency.  Moreover, use of these products in HVAC&R systems such as air ducts pose potential human exposure and health risks to applicators and building occupants which have not been assessed by the Agency.

This draft PR Notice provides guidance which, once final, the Agency would provide to  registrants concerning labeling language that EPA believes would address its current concerns for sanitizer, disinfectant and other antimicrobial products whose labels bear directions for use on, or incorporation within, hard, non-porous surfaces, but which have not been specifically approved for use in HVAC&R systems.  The PR Notice describes an Agency approach that registrants of products subject to this Notice should add a “Do Not Use” statement to the labeling of such products. Supporting documents for this draft PR Notice are contained in the docket.

## III.  Do PR Notices Contain Binding Requirements?

The PR Notice discussed in this notice is intended to provide guidance to EPA personnel and decision makers and to pesticide registrants.  While the requirements in the statutes and Agency regulations are binding on EPA and the applicants, this PR 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 assert that the guidance is not appropriate generally or not applicable to a specific pesticide or situation.
