Can assessments performed before the effective date of the rule be relied on as baseline assessments?
Integrity assessments conducted on category 1 pipelines after January 1, 1996 can be used as baseline assessments, provided they meet the criteria established by the rule. The corresponding date for category 2 pipelines is February 15, 1997. However, if an operator relies upon an assessment performed prior to March 31, 2002, (category 1) or February 18, 2003, (category 2) for purposes of establishing a baseline, that segment must be re-assessed in accordance with the rule’s provisions for subsequent assessments. This means that reassessment of segments for which pre-rule integrity assessments are used for a baseline must be conducted within five years following the dates those assessments were performed. For example, assume a pipeline segment that could affect an HCA was internally inspected in January, 1999, and that assessment met the rule’s requirements. If the operator elects to use this inspection as the baseline assessment for a particular segment, then this segment would have re
