The U.S. Environmental Protection Agency (EPA) awarded a $756,565 Project Grant to the Quinault Indian Nation (QIN) under the Diesel Emissions Reduction Act (DERA) National Grants program (CFDA 66.039). The grant will fund a project to repower one Tier 0 diesel main engine and two Tier 0 diesel auxiliary engines on a QIN vessel with EPA Tier 3 diesel engines. This engine replacement is expected to reduce annual emissions of nitrogen oxides by 49.4%, particulate matter by 43.1%, hydrocarbons by 52%, and carbon monoxide by 12.8%. The project has a period of performance from May 1, 2024 to April 30, 2026.
