May an operator designate an entire segment as HCA (i.e., covered by the rule)?
Yes, operators may designate an entire segment, or their entire pipeline, as covered by the rule. Operators will still need to gather information about the areas near their pipeline in order to consider differences in the consequences of pipeline accidents as part of their risk assessments and to identify appropriate preventive and mitigative measures. • FAQ-174. The centerline of a pipeline may not be accurately determined via GIS or other method. The locations of structures (e.g., from aerial photography) may also involve inaccuracies. What provisions must be taken to address for inaccuracies in these measurements, in order to accurately determine the relative location of structures with respect to the pipeline? [10/02/2006]Answer: The rule does not explicitly address mapping/measurement inaccuracies. Instead, it specifies the use of distances that apply to pipelines, and distances from those pipelines, as they actually exist in the field. The research behind the C-FER equation used
