Extension for Complying with Certain Antimicrobial Product Performance Test Guidelines to August 28, 2019

For Release: February 21, 2019

EPA is extending the testing compliance implementation deadline by six months for three final guidelines. EPA announced the availability of final test guidelines for “Series 810 – Product Performance Test Guidelines: Group B – Antimicrobial Efficacy Test Guidelines” on February 28, 2018. The Product Performance 810 Efficacy guidelines are a series of documents that provide recommendations for the design and execution of laboratory studies to evaluate the effectiveness of antimicrobial pesticides that work against public health pests.

The testing compliance date will be extended for the following three final guidelines:

Since the posting of the final 2018 guidelines, the agency has received extensive feedback and inquiries from stakeholders regarding the need for further clarification on various topics within the guidelines. For this reason, the agency is extending the testing compliance deadline to August 28, 2019, for the 2018 guidelines to allow for resolution of outstanding inquiries. The agency does not foresee any adverse implications to public health from this delay. In the interim, applicants may utilize either the 2012 or the 2018 final test guidelines for product performance testing.

All studies initiated after August 28, 2019, should utilize the revised 2018 guidelines for testing.

Documents pertaining to the revision of the test guidelines, including public comment submissions, and the agency’s response to comments are available at, in docket EPA-HQ-OPP-2015-0276.
