(minglett@suburbanpropane.com) 32024006NOA_Notice of Amendment_01112024_(23-264475)_text.pdf NOTICE OF AMENDMENT VIA ELECTRONIC MAIL TO: konderdonk@suburbanpropane.com; emoreno@suburbanpropane.com; minglett@suburbanpropane.com January 11, 2024 Keith Onderdonk Vice President of Operational Support Suburban Propane, L.P. 240 Route 10 West Whippany, NJ 07961 CPF 3-2024-006-NOA Dear Mr. Onderdonk: From April 24-27, 2023, a representative of the Pipeline and Hazardous Materials Safety Administration (PHMSA), pursuant to Chapter 601 of 49 United States Code (U.S.C.), conducted an onsite inspection of Suburban Propane, L.P’s (Suburban) Procedures for operations and integrity management in West Salem, Wisconsin. As a result of the inspection, PHMSA has identified the apparent inadequacies found within Suburban’s plans or procedures. The items inspected and the inadequacies are described below: 1. § 192.605 Procedural manual for operations, maintenance, and emergencies (a) General. Each operator shall prepare and follow for each pipeline, a manual of written procedures for conducting operations and maintenance activities and for emergency response. For transmission lines, the manual must also include procedures for handling abnormal operations. This manual must be reviewed and updated by the operator at intervals not exceeding 15 months, but at least once each calendar year. This manual must be prepared before operations of a pipeline system commence. Appropriate parts of the manual must be kept at locations where operations and maintenance activities are conducted. (b) Maintenance and normal operations. The manual required by paragraph (a) of this section must include procedures for the following, if applicable, to provide safety during maintenance and operations. (1) Operating, maintaining, and repairing the pipeline in accordance with each of the requirements of this subpart and Subpart M of this part. The Suburban Propane, L.P Operations and Maintenance Manual, last revised December 14, 2022, is inadequate because it does not require that leakage surveys be conducted with calibrated leak detector equipment outside business districts as frequently as necessary, but at least once every 5 calendar years at intervals not exceeding 63 months as required by § 192.723(b)(2). 2. § 192.613 Continuing surveillance. (a) Each operator shall have a procedure for continuing surveillance of its facilities to determine and take appropriate action concerning changes in class location, failures, leakage history, corrosion, substantial changes in cathodic protection requirements, and other unusual operating and maintenance conditions. (b) If a segment of pipeline is determined to be in unsatisfactory condition but no immediate hazard exists, the operator shall initiate a program to recondition or phase out the segment involved, or, if the segment cannot be reconditioned or phased out, reduce the maximum allowable operating pressure in accordance with § 192.619 (a) and (b). The Suburban Propane, L.P Operations and Maintenance Manual last revised December 14, 2022, is inadequate because it does not to require documentation of a program to recondition, phase out, or reducing the MAOP in a pipeline segment that is determined to be in unsatisfactory condition but for which no immediate hazard exists. 3. § 192.1007 What are the required elements of an integrity management plan? A written integrity management plan must contain procedures for developing and implementing the following elements:. . . . Suburban Propane did not develop a written integrity management plan as specified in § 192.1007. Suburban’s integrity management program incorrectly utilized § 192.1015 for a small liquefied propane gas (LPG) operator. The Suburban Terlingua system has 121 customers from a single source which exceeds the 100-customer-count specified by § 192.1001. Therefore, Suburban cannot be considered a small LPG operator.
