How to submit your application directly to EPA.

Action Code Interpretation
An application that requires the review of a modified protocol where only minor changes are made to an existing efficacy method (e.g. AOAC International, ASTM, AATCC, EPA guideline 810 or an AD approved method described in A431). The protocol should be submitted before any product registration testing has been done under the modified protocol. A draft label with proposed directions for use and use claims must accompany the protocol and the application. The draft label submitted with this application is not subject to the Agency’s approval. Examples of minor changes include (but are not limited to): varied test conditions, modification of standard method to support additional microorganisms [e.g., Germicidal Spray Products test for spore‐formers], changes to surface types/carriers, changes in inoculum preparation and inoculation, changes to required test microbes, and changes to support alternate application types [e.g., foams, electrostatic sprayer]. A pre‐registration meeting is strongly recommended prior to submission of the protocol. The Agency will make every effort during this meeting to determine if the protocol falls under the Tier 1 category. If, during further review, the Agency determines that a Tier l protocol should be elevated to Tier 2 status (A522), the applicant will receive notification prior to this change.
