We determined the Tennessee Valley Authority’s (TVA) coal plants have taken steps to reduce combustible coal dust since dedicated Combustible Dust Program funding was provided by TVA in 2018. Specifically, coal plants have dedicated combustible dust housekeeping crews to help mitigate combustible dust accumulations, and projects were completed to improve conditions at the plants. However, we identified areas of noncompliance with TVA Technical Safety Procedure 18.1205, Combustible Dust (Combustible Dust TSP), related to (1) coal dust accumulation, (2) documentation of combustible dust daily inspections, and (3) training. In addition, we identified an area for improvement related to inconsistent language in the Combustible Dust TSP and site combustible dust programs.
