Special State Registrations

Emergency Exemptions (Section 18) Registrations

Under Section 18 of FIFRA, state and federal agencies are allowed to permit the unregistered use of a pesticide in a specific geographic area for a limited time if emergency pest conditions exist. This typically arises when agricultural growers and others encounter a pest problem on a site for which there is either no registered pesticide available, or for which there is a registered pesticide that would be effective but is not yet approved for use on that particular site. Exemptions may also be approved for public health and quarantine reasons.

Federal regulations define an emergency condition as an urgent, non-routine situation that requires the use of a pesticide(s). Any emergency condition exists only when the situation is urgent and non-routine and all three conditions are met:

  1. No effective registered pesticides are available.
  2. No feasible alternative control practices are available.
  3. The situation a) involves the introduction or spread of a new pest, b) will present significant risks to human health or the environment, or c) will cause significant economic loss.

Special Local Need (SLN) – 24(c) Registrations

Under Section 24(c) of FIFRA, states can register a new pesticide product for any use, or a federally registered product for an additional use, as long as there is both a demonstrated "special local need," and a tolerance, exemption from a tolerance, or other clearance under the Federal Food, Drug, and Cosmetic Act (FFDCA). EPA has the authority to disapprove a state's special local need registration application.

An SLN is defined, in 40 CFR 162.151(i) as an existing or imminent pest problem within a state for which the state lead agency, based upon satisfactory supporting information has determined that an appropriate federally registered pesticide is not sufficiently available.

For both Section 18 and SLNs, OISC will work with local personnel to confirm the need in the state. Once a need is identified, OISC will contact the registrant and identify the next steps.

Annual Renewals:

SLNs and Section 18s require annual renewal in the state of Indiana. Renewal form will be sent to the registrant in mid-October.


Expiration Dates:

SLN labels expire within five years of the initial registration. OISC will confirm that the special local need still exists and request a revised SLN label prior to the expiration.

OISC will work with registrants on any needs connected to extending the expiration (revised labels) or cancelling the SLN. OISC will submit all required documents to EPA.
