UST Program - Leak Prevention - Frequently Asked Question #12

Question: Are monthly Designated UST Operator inspections required when a UST facility is in temporary closure?

Answer: No. When a UST facility is in temporary closure as described in California Code of Regulations, Title 23, section 2671, monthly inspections by a Designated UST Operator are not required. Instead, UST facilities in temporary closure must be inspected at least every three months by the owner /operator as described in section 2671(c). Recordkeeping requirements still apply while the UST facility is in temporary closure, so the UST owner/operator must maintain Designated UST Operator monthly inspections reports from the 12 months prior to the facility going into temporary closure. Monthly Designated UST Operator inspections must resume once the facility is put back into service.
