Class 1 transmission line operators in Pennsylvania must register lines with the Pennsylvania Public Utility Commission this month, if they haven't already, after it voted Thursday to issue a final order toward implementing a gas line safety act, the commission said.
Pipelines are classified based on proximity to buildings, with the higher classifications indicating a higher density of buildings intended for human habitation near the pipelines, said Denise McCracken, a spokeswoman for the commission.
Class 1 locations are defined as offshore areas or any so-called class location units with 10 or fewer buildings intended for human occupancy, according to a commission news release.
Thursday's board action was a clarification of the commission's implementation order, and Class 1 operators must now file by June 22, according to a news release.
The Gas and Hazardous Liquids Pipelines Act, or Act 127, directed the commission to develop a registry and conduct safety inspections of nonpublic utility gas and hazardous liquids pipeline equipment and facilities in the state, according to a news release.
