If the source is an aboveground component that can be inspected visually, the component shall be repaired and may be returned to service without secondary containment as long as the requirements of sub. (6) are satisfied. If a component is replaced to comply with the requirements of this paragraph, that component shall satisfy the requirements for new tank systems or components in ss. NR 665.0192 and 665.0193. Additionally, if a leak has occurred in any portion of a tank system component that is not readily accessible for visual inspection (e.g., the bottom of an inground or onground tank), the entire component shall be provided with secondary containment in accordance with s. NR 665.0193 prior to being returned to use.
NR 665.0196(6) (6)Certification of major repairs. If the owner or operator has repaired a tank system in accordance with sub.
