SUPPLEMENTARY INFORMATION:

I. General Information

    The EPA is making two aquatic toxicity reports, submitted by Tidal 
Vision Products, LLC, available for public comment. The EPA seeks input 
from stakeholders on how these reports may be used to inform the 
Agency's assessment of the aquatic toxicity of chitosan and its salts.
    On November 2, 2020, the EPA published ``Pesticides; Proposal to 
Add Chitosan to the List of Active Ingredients Permitted in Exempted 
Minimum Risk Pesticide Product,'' 85 FR 69307 (FRL-10009-24). The 
proposed rule addressed the subject matter of a 2018 petition by Tidal 
Vision Products LLC that requested that the substance commonly known as 
chitosan (also known by its chemical name poly-D-glucosamine) (CAS Reg. 
No. 9012-76-4) be added to the list of active ingredients allowed in 
exempted minimum risk pesticide products under 40 CFR 152.25(f)(1).
    Public comments on the proposed rule discussed these salts. The EPA 
notes that chitosan may form as a salt (e.g., acetate, lactate, 
hydrochloride, and salicylate) when it is solubilized in acids for end 
use product formulation and subsequently applied in the environment. 
The new information submitted by Tidal Vision pertains to these salts.
    As authorized by the Federal Insecticide, Fungicide, and 
Rodenticide Act (FIFRA) section 25(b), the EPA has exempted from the 
requirement of registration certain pesticide products if they are 
composed of specified

[[Page 27060]]

ingredients (recognized active and inert substances which are listed in 
the regulations) and labeled according to the EPA's regulations in 40 
CFR 152.25(f). The EPA created the exemption for minimum risk 
pesticides to eliminate the need for the Agency to expend significant 
resources to regulate products that were deemed to be of minimum risk 
to human health and the environment. Prior to submission of these 
aquatic toxicity reports, the EPA received a petition from Tidal Vision 
Products, LLC, requesting that the substance commonly known as chitosan 
(also known by its chemical name poly-D-glucosamine) (CAS Reg. No. 
9012-76-4) be added to the list of active ingredients allowed in 
exempted minimum risk pesticide products under 40 CFR 152.25(f)(1). 
This matter was the subject of a proposed regulation (85 FR 69307) 
(FRL-10009-24).
    The EPA is considering the information submitted by Tidal Vision in 
its decision regarding whether to finalize the proposal to add chitosan 
to the list of permitted active ingredients, and if so, whether and how 
to address chitosan salts in the exemption.
