A petition to amend an existing tolerance on domestic or imported crops and for which there is not a related label amendment request necessitating the proposed tolerance amendment. This may be a request to increase or decrease an existing tolerance currently established under section 408 of the FFDCA. The fee for this category applies to each additional food use to which the requested tolerance amendments apply, up to 5 uses (i.e. the fee for this category is multiplied by 4 if 4 uses are proposed). If tolerance amendments are being requested for six or more uses, the fee category R297 applies. This category is applicable when a tolerance amendment is being requested but no related label amendment is necessary or being requested. Examples of situations to which this category might apply include but are not limited to requests to amend an existing tolerance (decrease level), requests to increase an existing tolerance to reflect residue data demonstrating higher observed residues than the existing tolerance, or requests to move an existing tolerance from one paragraph to another within the citation in 40 CFR Part 180. Examples of food uses include: use on foods, for example, corn or apples; aquatic uses involving potable water, irrigation, or requiring tolerances for fish, or shellfish; uses on areas where food may be grown or raised such as pasture, rangeland, home garden, beehive, and uses involving livestock, such as livestock housing, livestock dips, and livestock ear tags.
