Special Review Process

Pesticide Reevaluation

EPA uses the Pesticide Special Review process when it has reason to believe that the use of a pesticide may result in unreasonable adverse effects on people or the environment. The Special Review process usually involves intensive review of only a few or just one potential risk. The review involves evaluating existing data, acquiring new information and/or studies, assessing the identified risk and determining appropriate risk reduction measures.

Known formerly as the Rebuttable Presumption Against Registration (RPAR) process, Special Review provides a mechanism for public input into EPA’s deliberations before the Agency issues a Notice of Final Determination describing its selected regulatory action. The Special Review process determines whether some or all registrations of a particular active ingredient or ingredients meet the federal standard for registration, or whether amendment or cancellation of portions or all of the registrations is appropriate. Since the 1970s, EPA has reviewed more than 100 pesticides under the Special Review process.

Actions Regarding Chemicals in Special Review

Since the inception of the Special Review process, EPA has conducted and concluded Special Review on many pesticides (PDF) (65 pp, 111 MB, About PDF). The Agency now has only a few pending Special Review decisions to complete.

Possible Outcomes of the Special Review Process

The decision to begin Special Review does not necessarily mean that the pesticide poses unreasonable risks and will be canceled. Special Reviews may end with a determination that the pesticide does not pose such risks, or that it may require other risk reduction measures such as labeling changes or removal of certain uses.

Faster Alternatives to the Full Special Review Process

The ultimate goal of the Special Review process is to reduce the risks posed by a pesticide. This includes considering both the risks and benefits provided by the use of the pesticide to the extent permissible under law. Completing the full Special Review process can take many years because of the extensive amount of data that must be collected and reviewed.

Where appropriate, EPA employs alternative approaches to develop timely decisions and risk reduction measures. For example, EPA has conducted the Special Review program along with tolerance reassessment and reregistration for older pesticides. EPA is planning to complete Special Reviews for many of the chemicals currently in the process in conjunction with reregistration, and EPA is consolidating its reviews to expedite decision-making.

Possible alternatives to using the full Special Review process include:

These alternatives are not intended to replace the conventional, intensive Special Review process. EPA may use some of the alternatives concurrently with the conventional process to achieve timely risk reduction of critical concerns while the overall review continues. In other cases, the alternative steps are used to quickly reduce risk concerns associated with the use of a pesticide before it is placed in the formal Special Review process.
