District of Columbia DOE adopted operator training rules in 2009 that are similar to EPA guidelines. Deadline was 8/12/2012.
Our DC Class C online course is available and considered acceptable in District of Columbia. After the initial training, Class C operators shall be briefed by the Class A or B operator on these instructions or procedures at least annually (every 12 months). We also suggest retaking the Class C course and filling out the worksheet again. If you’re coming back for a refresher here’s how you do it in your account.
See the District of Columbia DOE UST web page for more information.
