D.C. Mun. Regs. tit. 24, r. 24-219
When the Director considers it in the public interest to construct or authorize construction of any utility in, through, under, over, or in place of any vault, the Director shall request the Director of Consumer and Regulatory Affairs to serve a notice on the owner stating the need for the vault space, what portion is required, and the date by which it must be available.
Within the time specified in the notice required by § 219.1, the owner shall do any work that is necessary to clear the required space.
The Director is authorized to accept an arrangement between the owner and the utility company under which the utility company shall do all or part of the required work on the vault in conjunction with the utility installation.
An arrangement as authorized by § 219.3 shall not relieve the owner of any responsibility under the vault permit and the recorded agreement.
All abandonment or alteration effected by the utility company shall be under permit, and to Department specifications.
When any change proposed to be made in the roadway, sidewalk, or other surface adjoining a vault will affect the vault, the owner shall be notified as provided in § 219.1; and he or she shall make all necessary modifications to the vault within the specified time.
