This comes through a revised 2021 Shipboard Technology Evaluation Program (STEP) Application Package, published by the USCG Office of Operating and Environmental Standards.

The STEP application incorporates fully validated experimental design parameters developed through the US Environmental Protection Agency’s Environmental Technology Verification (ETV) process, as well as ETV harmonized shipboard testing requirements.

The revised format is intended to assist applicants to prepare and submit all necessary information in a clear and consistent manner, thus facilitating the review process. Potential applicants should familiarize themselves with the guidance before completing the application,

...the USCG explained.

The application and instructions for submitting are available on the Office of Operating and Environmental Standards webpage.

The Navigation and Vessel Inspection Circular 01-04 (NVIC 01-04) establishes the process and gives additional information for vessel owners to apply to STEP.
