Underground Storage Tanks (UST)
Environmental Health conducts Underground Storage Tank (UST) permitting, construction plan checks, inspections, and tank closure activities.
Environmental Health classifies UST repairs, modifications and upgrades into two categories: work requiring a permit, and no permit required. These categories are determined by the scope of work and the need for a site inspection. UST work requiring a permit involves the submission of a UST Permit Application, a technical review of the proposed work, equipment to be used and contractor information and at least one site inspection. It may also include soil and/or ground water sampling. If the proposed work is approved, a UST Installation, Modification or Repair letter will be issued by Environmental Health to both the UST owner and the contractor. It will list site-specific construction and inspection requirements. No UST construction activities can proceed prior to the issuance of this letter. Work can begin upon receipt of the approval letter.
For assistance in determining the classification of repairs to be made to your UST system please refer to the UST Installation Modification Repair Guide or contact us.
