You inquired how you could deactivate the plant, and still retain the grandfather\nclause for the plant so that it can be brought back into operation without having to meet the current LNG design and\nconstruction requirements.\nFrom a review of Section 193.2005(b), a facility constructed in the 1960's, would not have to comply with the applicable\nrequirements of Part 193 governing siting, design, installation and construction unless the facility is replaced, relocated,\nor significantly altered. Other sections of Part 193 which are pertinent are:\n1. Section 193.2603(b) states that an operator may not return to service any component which is not maintained in\naccordance with Subpart G.\n2. Section 193.2619(b) states that a control system which out of service for 30 days or more must be inspected and\ntested for operational capacity before returning it to service.\nI trust that this clarifies this matter.\nSincerely,\nJack C. Overly\nChief\nWestern Region Pipeline Safety\nOffice of Operations and Enforcement","truncated":false,"body_characters":1439}
