EPA Announces Approval of Extensions to August 24, 2020, First-Ever Long-Lasting Antiviral Product for Use against COVID-19

Lisa M. Campbell Heather F. Collins, M.S.

On January 19, 2021, the U.S. Environmental Protection Agency (EPA) announced the issuance of a Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 18 emergency exemption to the states of Oklahoma and Arkansas, permitting American Airlines to use SurfaceWise2, believed to inactivate coronaviruses like the SARS-CoV-2 virus on surfaces, in specific airport facilities and planes.  EPA also has revised the terms of use for SurfaceWise2 for all current emergency exemptions. 

EPA’s initial emergency exemption for the state of Texas issued on August 24, 2020, specified that the product remained effective for seven days.  According to its updated labels for all three states, EPA has now approved claims that SurfaceWise2 provides residual surface control of the coronavirus SARS-CoV-2 on surfaces that are undisturbed for up to 30 days.  The updated labels state “When used in accordance with the directions for use, SurfaceWise®2 provides residual surface control of coronaviruses, including SARS-CoV-2, for up to 30-days on undisturbed (e.g., are not routinely disinfected with List N products) non-porous treated surfaces.” 

Of note, EPA also states in its announcement that SurfaceWise2 should be reapplied every time surfaces are disinfected to ensure continuous product performance as exposure to prolonged wetness may adversely impact the efficacy of the product.  The updated labels state in the Directions for Use that the user must “Reapply SurfaceWise®2 after surfaces are disinfected to ensure continuous product performance” and “Do not expose SurfaceWise®2 to prolonged wetness as this may adversely impact the efficacy of the product.”

FIFRA Section 18 authorizes EPA to exempt federal or state agencies from any provision of FIFRA in the event that emergency conditions require such an exemption.  EPA regulations (40 C.F.R. Part 166) specify when state or federal government agencies will be permitted to use unregistered pesticides in response to an emergency.  EPA’s regulations provide that an emergency exists when:

  • There is an “urgent, non-routine” situation requiring the use of a pesticide to control a new pest not previously prevalent in the United States, to control significant risks to health, the environment, beneficial organisms, or endangered species, or to prevent specified types of economic loss; and
  • There is no registered pesticide or economically or environmentally feasible alternate method of control available.

40 C.F.R. § 166.3.

The exemptions granted can be very specific and time-limited; EPA has developed a database so companies can search (by chemical, site, pest, applicant, or date range) to determine if an emergency exemption has been issued and its expiration date.

In this case, EPA approved the Section 18 emergency exemption request for SurfaceWise2 — a product manufactured by Allied BioScience.  SurfaceWise2 is a surface coating that Allied BioScience states inactivates viruses and bacteria within two hours of application and continues to work against them for up to 30 days, on undisturbed non-porous treated surfaces.  EPA’s approvals will allow Texas, Oklahoma, and Arkansas to permit American Airlines airport facilities and planes at specific locations identified on the label and two Total Orthopedics Sports & Spine Clinics in Texas to use SurfaceWise2 under certain conditions.  The approved Section 18 emergency requests are effective for one year. This public health exemption will expire August 24, 2021.  As new data emerge, EPA may alter the terms of the product’s emergency uses, as it did with the modifications discussed here.
