District of Columbia Code Division V. Local Business Affairs § 34-401. Utilities to report accidents; Commission may investigate.

(a) Every public utility shall, whenever an incident occurs within the District of Columbia that results in the loss of human life, personal injury requiring hospitalization, or service disruption directly or indirectly arising from or connected with its maintenance or operation, give immediate notice thereof to the Public Service Commission and the Office of the People's Counsel of the District of Columbia. In the event of any such incident, the public utility shall also submit a written report to the Commission that explains the cause of the incident, what steps if any the public utility will undertake to prevent such an occurrence in the future, and such other information which the Public Service Commission shall, by order or regulation, require. The Commission, by regulation or order, shall establish the minimum criteria for a service disruption (e.g., time period or minimum number of affected customers) that warrants notification and a report under this section. The Commission, if it deems the public interest requires it, shall cause an investigation to be made of any incident.

(b) The report required by subsection (a) of this section shall not be admitted into evidence for any purpose in any suit or action for damages arising out of the loss of life, injury, or service interruption referred to in this subtitle.
