D.C. Mun. Regs. r. 21-739
A solid waste facility shall immediately cease operation without additional notice if:
The owner or operator of a solid waste facility which voluntarily and permanently ceases operations shall notify the Director in writing five (5) days prior to the closing. Failure to notify the Director shall constitute abandonment of the facility.
The owner or operator of a solid waste facility which permanently ceases operations, whether voluntarily or involuntarily, shall remove all solid waste from the facility within twenty-four (24) hours following the closing. The facility shall also be thoroughly cleaned, including floors, walls, and all equipment used to handle solid waste.
In the event that the owner or operator of a solid waste facility fails to act in accordance with § 739.3, the Director may issue a written notice directing compliance.
If the owner or operator fails to comply with the written notice issued pursuant to § 739.4 within the time period stated in the notice, the Director may remove the solid waste from the facility, clean the facility, and take any other corrective actions as are necessary to safeguard human health, the public welfare, or the environment.
The Director may assess a penalty against the person or persons named in the written notice issued pursuant to § 739.4 equal to triple the costs of undertaking the actions undertaken pursuant to § 739.5. The costs and penalties may be recouped by the District from the facility's environmental mitigation bond, or by a lien against the real property and or equipment or any other method available under the law.
