On the basis of the inspection, PHMSA has identified the apparent inadequacies found within Century Aluminum’s procedures, as described below: 1. § 192.12 Underground natural gas storage facilities. (a) … (c) Procedural manuals. Each operator of a UNGSF must prepare and follow for each facility one or more manuals of written procedures for conducting operations, maintenance, and emergency preparedness and response activities under paragraphs (a) and (b) of this section. Each operator must keep records necessary to administer such procedures and review and update these manuals at intervals not exceeding 15 months, but at least once each calendar year. Each operator must keep the appropriate parts of these manuals accessible at locations where UNGSF work is being performed. Each operator must have written procedures in place before commencing operations or beginning an activity not yet implemented. Century Aluminum’s written procedures for conducting operations, maintenance, and emergency preparedness and response activities were inadequate to ensure safe operation of a pipeline facility. Specifically, Century Aluminum failed to include a procedure for monitoring the presence of annular gas by measuring and recording annular pressure and/or annular gas flow in accordance with API RP 1171, Section 9.3.2 Well Integrity Monitoring (Section 9.3.2). Section 9.3.2 states in part, “[t]he operator shall monitor for presence of annular gas by measuring and recording annular pressure and/or annular gas flow.” During the inspection, PHMSA requested Century Aluminum’s procedures for monitoring the presence of annular gas by measuring and recording annular pressure and/or annular gas flow. Century Aluminum provided the Storage Integrity Management Plan (SIMP), Section 4. However, the SIMP failed to include a process for monitoring the presence of annular gas by measuring and recording annular pressure and/or annular gas flow. Therefore, Century Aluminum’s written procedures required by §192.12(c) were inadequate. Century Aluminum must revise its procedures to address the deficiency outlined above. 2. § 192.12 Underground natural gas storage facilities. (a) … (c) Procedural manuals. Each operator of a UNGSF must prepare and follow for each facility one or more manuals of written procedures for conducting operations, maintenance, and emergency preparedness and response activities under paragraphs (a) and (b) of this section. Each operator must keep records necessary to administer such procedures and review and update these manuals at intervals not exceeding 15 months, but at least once each calendar year. Each operator must keep the appropriate parts of these manuals accessible at locations where UNGSF work is being performed. Each operator must have written procedures in place before commencing operations or beginning an activity not yet implemented. Century Aluminum’s written procedures for conducting operations, maintenance, and emergency preparedness and response activities were inadequate to ensure safe operation of a pipeline facility. Specifically, Century Aluminum failed to establish an annual frequency for testing the operation of the master valve and wellhead pipeline isolation valve for proper function and ability to isolate the well in accordance with Section 9.3.2 Section 9.3.2 states in part, “[t]he operator shall test the operation of the master valve and wellhead pipeline isolation valve at least annually for proper function and ability to isolate the well.” During the inspection, PHMSA requested Century Aluminum’s procedures regarding testing of the master valve and wellhead pipeline isolation valve for proper function. Century Aluminum provided its SIMP, which failed to establish an annual frequency requirement for testing of the operation of the master valve and wellhead pipeline isolation valve for proper function and ability to isolate the well. Therefore, Century Aluminum’s written procedures required by §192.12(c) were inadequate. Century Aluminum must revise its procedures to address the deficiency outlined above. 3. § 192.12 Underground natural gas storage facilities. (a) … (c) Procedural manuals. Each operator of a UNGSF must prepare and follow for each facility one or more manuals of written procedures for conducting operations, maintenance, and emergency preparedness and response activities under paragraphs (a) and (b) of this section. Each operator must keep records necessary to administer such procedures and review and update these manuals at intervals not exceeding 15 months, but at least once each calendar year. Each operator must keep the appropriate parts of these manuals accessible at locations where UNGSF work is being performed. Each operator must have written procedures in place before commencing operations or beginning an activity not yet implemented. Century Aluminum’s written procedures for conducting operations, maintenance, and emergency preparedness and response activities were inadequate to ensure safe operation of a pipeline facility. Specifically, Century Aluminum failed to include a procedure to define a threshold or limit for the annular pressure and/or annular gas flow and to evaluate annular gas occurrences in accordance with Section 9.3.2. Section 9.3.2 states in part, “[t]he operator shall evaluate each annular gas occurrence that exceeds operator- or regulatory-defined threshold levels determined from well integrity evaluation and from risk assessment.” During the inspection, PHMSA requested Century Aluminum’s procedures regarding evaluating annular gas occurrences. Century Aluminum provided its SIMP, which failed to include a process for determining threshold levels from well integrity evaluation and from risk assessment. The SIMP also failed to include a process for evaluating each annular gas occurrence that exceeds operator- or regulator-defined thresholds. Therefore, Century Aluminum’s written procedures required by §192.12(c) were inadequate. Century Aluminum must revise its procedures to address the deficiency outlined above.
