237 | 233 | notification to OPS is required in accordance with Part 192.949, 180 |
238 | 234 | days before conducting the assessment. Also, verify that notification |
239 | 235 | to a State or local pipeline safety authority is required when either |
240 | 236 | a covered segment is located in a State where OPS has an interstate |
241 | 237 | agent agreement, or an intrastate covered segment is regulated by that |
242 | 238 | State. [§192.921(a)(4)] |

| 503 | B31.8S, section 4.2.1, section 4.4, and Appendix A [ASME B31.8S, 4.1, |
| 504 | 4.2.1, 4.4, 5.7(e), and Appendix A]: |
| 505 | i. Each threat covered by the missing or suspect data is assumed to |
| 506 | apply to the segment being evaluated. The unavailability of identified |
| 507 | data elements is not a justification for exclusion of a threat. |
| 508 | ii. Conservative assumptions are used in the risk assessment for that |
| 509 | threat and segment or the segment is given higher priority. |
| 510 | iii. Records are maintained that identify how unsubstantiated data are |
| 511 | used, so that the impact on the variability and accuracy of |
| 512 | assessment results can be considered. |
| 513 | iv. Depending on the importance of the data, additional inspection |
| 514 | actions or field data collection efforts may be required. |
