Potentially affected entities may include:

• Food manufacturing (NAICS code 311).
• Pesticide manufacturing (NAICS code 32532).
If you have any questions regarding the applicability of this proposed action to a particular entity, consult the person listed under *FOR FURTHER INFORMATION CONTACT* .
**B. What should I consider as I prepare my comments for EPA?**
1. *Submitting CBI.* Do not submit CBI to EPA through email or *https://www.regulations.gov.* If you wish to include CBI in your comment, please follow the applicable instructions at *https://www.epa.gov/dockets/commenting-epa-dockets#rules* and clearly mark the information that you claim to be CBI. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2.
**C. What is EPA's authority for taking this action?**
Under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) (7 U.S.C. 136p), at the discretion of the EPA Administrator, a Federal or State agency may be exempted from any provision of FIFRA if the EPA Administrator determines that emergency conditions exist which require the exemption. EPA implementing regulations are set forth in 40 CFR part 166.
**II. What action is the Agency taking?**
EPA is announcing receipt of requests submitted to EPA under FIFRA section 18. This notice does not constitute a decision by EPA on the application itself. The regulations governing FIFRA section 18 require publication of a notice of receipt of an application for a specific exemption proposing use of a new chemical ( *i.e.,* an active ingredient) which has not been registered by EPA.
**II. Summary of the Request Received**
The Arkansas and Missouri Departments of Agriculture have requested the EPA Administrator to issue specific exemptions for the use of tetflupyrolimet on rice to control Barnyardgrass resistant to multiple herbicides. Information in accordance with 40 CFR part 166 was submitted as part of this request. As part of this request, the applicants assert that emergency conditions exist due to insufficient means to control Barnyardgrass resistant to rice herbicides, especially Barnyardgrass resistant to multiple herbicides, which leaves rice growers without an effective control option. The use of tetflupyrolimet will help avert significant economic losses.
The Applicants propose to make up to two applications of 8.6 fluid ounces of the unregistered product, KEENALI HERBICIDE (containing 35.0% tetflupyrolimet, equivalent to 3.34 lbs. of tetflupyrolimet per gallon of product) on up to a total of 646,000 acres of rice (546,000 in Arkansas and 100,000 in Missouri), from March 1, 2026 to July 1, 2026. If a maximum of two applications are made to the maximum requested acreage, a potential of 43,399 gallons of product (equivalent to 146,080 pounds of tetflupyrolimet) could be used.
The Agency will review and consider all comments received during the comment period in determining whether to issue the specific exemptions requested by the Arkansas and Missouri Departments of Agriculture.
