toxins on the Internet at (http:// 

www.regulations.gov/fdmspublic/component/ 

main?main=DocketDetail&d=APHIS-2009-0070). 

comments on the current list1 of select 

agents and toxins and on any other 

significant pathogens so as to inform the 

working groups as they begin the 

biennial review process. 

Reorganization of Current List of 

Select Agents and Toxins 

We are also seeking public comment 

regarding potential reorganization of the 

list of select agents and toxins. Recent 

reports by the National Academies, the 

Executive Order 13486 Working Group, 

and the National Science Advisory 

Board for Biosecurity have 

recommended tiering the list of select 

agents and toxins based on the relative 

potential of each to be misused. If 

implemented, such tiering could allow 

for the application of different security 

measures for those select agents or 

toxins that pose a higher risk to animal 

or plant health if they were to be stolen 

or otherwise misused. 

For those commenters who believe 

tiering the list of select agents and 

toxins is advisable, we also welcome 

recommendations as to what criteria 

should be used to designate high risk 

select agents and toxins. For example, 

potential tiering of the select agent and 

toxin list could reflect one or more of 

the following: 

∑ The relative ease with which a 

particular select agent or toxin might be 

disseminated or transmitted from one 

animal to another or into the 

environment where it could produce a 

deleterious effect upon animal or plant 

health; 

∑ The potential for high animal or 

plant mortality rates; 

∑ The potential for a major animal or 

plant health impact; 

∑ Select agents or toxins whose 

misuse might result in public panic or 

other social or economic disruption; 

∑ Select agents or toxins whose use 

might require Federal, State, and/or 

local officials to take special action in 

planning for major animal or plant 

health disasters. 

Additionally, we are interested in any 

potential corresponding changes to the 

security requirements of the current 

regulations that would be necessary to 

provide appropriate protection of higher 

tier select agents or toxins and whether 

such changes should be prescriptive or 

performance based. 

At the conclusion of the working 

group review process, we will publish 

another document in the Federal 

Register either republishing the lists of 

select agents and toxins in 7 CFR 331.3, 

9 CFR 121.3, and 9 CFR 121.4 or 

proposing changes to one or more of the 

lists. The document may also include 

reorganization of the lists of select 

agents and toxins via tiering of the 

select agents or toxins themselves and/ 

or tiered security requirements. 

This action has been determined to be 

significant for the purposes of Executive 

Order 12866 and, therefore, has been 

reviewed by the Office of Management 

and Budget. 

Authority: 7 U.S.C. 8401; 7 CFR 2.22, 2.80,
