PHMSA has hired a contractor to update the location of Ecological Unusually Sensitive Areas for Liquid IMP HCA analysis. The update is scheduled for Q4 2024. While we can’t pinpoint the exact release date by PHMSA, it’s likely to hit the public domain sometime in November or December 2024. Operators will then need to use this updated dataset for their ”could affect” analysis that determines which liquid pipeline segments are required to be in their integrity management plans.
Note that PHMSA requires liquid pipeline operators to conduct a “could affect” analysis even if they voluntarily include all of their pipe segments in their IMP.
RCP’s GIS experts will be prepared to use this new dataset to assist our clients in their HCA analysis as soon as it is released. For further information, please message Jessica Foley.
