EPA Seeks Public Comment on Pesticide Applications Adding Hemp as a New Use Site
By Lisa M. Campbell and Timothy D. Backstrom
On August 23, 2019, the U.S. Environmental Protection Agency (EPA) issued a Federal Register notice announcing the receipt of 10 applications to amend currently registered pesticide products to add hemp as a new use site. The 10 application amendments are the result of the 2018 Farm Bill, signed in to law on December 20, 2018, that removed hemp from the Controlled Substances Act and legalized commercial use and production of hemp that contains less than 0.3% tetrahydrocannabinol (THC).
EPA states in the notice that Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 3(c)(4) does not require EPA to provide notice and opportunity to comment concerning these 10 applications because hemp falls within the terrestrial outdoor and residential outdoor use pattern previously approved for the pesticidal active ingredients in question, and approval of the applications would therefore not involve "a changed use pattern." Instead, EPA states that it has decided to provide an opportunity to comment in this instance "because of the potential significant interest from the public" and to be "completely transparent about these applications." EPA also states that it does not intend to provide notice or opportunity to comment for similar applications to add hemp that are likely to be submitted in the future.
EPA also states that the products with requested label amendments contain active ingredients for which EPA "has previously determined the residues will be safe under any reasonably foreseeable circumstances." Each active ingredient has an established tolerance exemption for residues on all raw agricultural or food commodities.
The 10 products for which EPA has received an application to add hemp are:
Once public comments are received, EPA anticipates making its decision on adding hemp as a new use site on the specific products before the end of 2019, so that these products may be available for the 2020 growing season.
Although the Federal government has legalized commercial production and use of hemp (as opposed to marijuana that contains higher levels of THC), not every State has changed its laws to conform to the new classification. EPA took the unusual step of announcing receipt of the new amendment applications at Hemp Production Field Day at the University of Kentucky. Senator Rand Paul of Kentucky has long been a proponent of commercial hemp production, and about 1,000 growers in Kentucky now have licenses to grow hemp for commercial use.
As hemp production increases, there will also be increased demand for pesticides to combat weeds, insects, and plant diseases that pose a potential threat to this crop. Although hemp fiber and oil have many potential industrial uses, hemp also has potential medicinal uses because extracts containing cannabidiol (CBD) are now being widely marketed for their purported health benefits. This use of hemp means that EPA will have to consider whether new tolerances may be required for some active ingredients before they can applied to hemp. As EPA has noted, the active ingredients in the 10 products for which EPA announced that applications are pending to add labeling for hemp already have tolerance exemptions, and therefore do not present this issue.
Comments are due on or before September 23, 2019. The public can submit comments at www.regulations.gov in Docket Number EPA-HQ-OPP-2019-0369.
