From the 3/26/20 Memo: COVID-19 Implications for EPA’s Enforcement and Compliance Assurance Program
Many training classes are offered on-line and such on-line training generally should not be affected by travel and social distancing constraints. If practicable, sectors mandated to function with certified operators should maintain normal certification and training practices. If not practicable due to the COVID-19 pandemic, the EPA believes that it is more important to keep experienced, trained operators on the job, even if a training or certification is missed.
