EPA Approves Emergency Exemption for Surface Coating that Continuously Kills COVID-19

This original announcement was published by the EPA on April 22, 2021. Click here for more information.


Today, the U.S. Environmental Protection Agency (EPA) approved emergency exemption requests from Georgia, Utah, and Minnesota, allowing BIAXAM, a supplemental residual surface coating. EPA is issuing an emergency exemption for BIAXAM to be used in Delta Air Lines planes and facilities in those three states.

BIAXAM is an adhesive film that can be applied by trained applicators to a range of hard, non-porous surfaces like gate counters, seat backs, overhead storage, and touch screens. Laboratory testing data submitted by the applicant indicates that BIAXAM kills 99.999% of SARS-CoV-2 particles that land on the film within two hours. Based on differences in cleaning and disinfection frequency and protocols used in airport terminals vs. airplanes, it remains effective for up to 100 days on airport surfaces and up to 200 days on airplane surfaces.

Recent information from the Centers for Disease Control and Prevention (CDC) notes that the risk of being infected with COVID-19 by touching contaminated surfaces is considered low. This product serves as an additional tool in limited use situations to aid in the fight against the virus and does not replace routine cleaning and disinfection. Always follow CDC, state, and local public health guidelines.

EPA Releases Analysis of Groundwater Model for Public Comment

This original announcement was published by the EPA on April 16, 2021. Click here for more information.


The U.S. Environmental Protection Agency (EPA) is releasing its Analysis of Subsurface Metabolism in Groundwater Modeling for public comment. This report evaluates assumptions used in Pesticide in Water Calculator groundwater modeling, which EPA developed to estimate pesticide concentrations in vulnerable groundwater sources and is used in human dietary risk assessments.

EPA will take comments on the Analysis for 45 days, starting on April 15, 2021. You can submit comments online in docket EPA-HQ-OPP-2021-0241 at www.regulations.gov. EPA will carefully consider public input when evaluating whether changes in the methodology for estimating pesticides concentrations in groundwater are necessary.

EPA Releases Final Biological Evaluations of Carbaryl and Methomyl’s Impacts on Endangered Species

This original announcement was published by the EPA on March 31, 2021. Click here for more.


EPA is taking the next step in its regulatory review of carbaryl and methomyltwo insecticides used on a variety of food and feed crops. Carbaryl is also registered for residential uses, in areas like home gardens and lawns.

After carefully considering public comments on the draft biological evaluations (BEs) for carbaryl and methomyl, today, EPA is releasing its final BEs, which find that these insecticides are “likely to adversely affect” a number of threatened and endangered species and their designated critical habitats.

Since the findings of the BEs include potential adverse effects on listed species, EPA will need to engage in formal consultation with the U.S. Fish and Wildlife Service and the National Marine Fisheries Service (the Services) to further study these potential impacts and possibly propose mitigation measures for vulnerable species. EPA’s final BEs are being submitted to the Services to begin this process. EPA is also considering additional mitigation measures, including prioritizing mitigation measures for certain vulnerable species while in consultation with the Services.

Biological evaluations are the beginning of EPA’s Endangered Species Act consultation review process for pesticides. EPA followed its March 2020 Revised Method for National Level Listed Species Biological Evaluations of Conventional Pesticides to conduct this biological evaluation. In order to make its “likely to adversely affect” determination, EPA evaluated whether an individual of a listed species is “reasonably expected” to be exposed to the pesticide at a sufficient level that it will have an effect, and whether that effect will be adverse.

The Services will use this information to develop their biological opinions to determine if the pesticides jeopardize the continued existence of any of the listed species and whether there is adverse modification to their critical habitats. If jeopardy or adverse modification is determined, the Services, with input from EPA and the registrants, will propose protection measures as appropriate. Protection measures would be designed to reduce potential harm to listed species or their critical habitat.
