What is an Underground Storage Tank?
An underground storage tank (UST) is one or multiple tanks, including pipes, beneath the sidewalk and/or roadway surface which are typically used for the storage of hazardous substances and wastes that are potential sources of contamination of the ground and underlying aquifers. These hazardous substances and contaminants may pose other dangers to public health and the environment as defined under the State Health and Safety Code (Chapter 6.7, Division 20) and the California Underground Storage Tank Regulations (Subchapter 16 of Title 23 of the California Code Regulations).
Under SF Public Works Code (Article 2.4, Section 2.4) and SF Public Health Code (Article 21, Section 1120), a permit is required for excavation of the Public Right-of-Way for the removal of any UST. For information regarding permits from Department of Public Health (DPH), please contact DPH directly at (415) 252-3800.
