LAS VEGAS — The Bureau of Land Management has extended the scoping period to gather public comments on the proposed GridLiance West Core Upgrades Transmission Line Project to upgrade the existing 155-mile single-circuit 230 kV transmission system in Clark and Nye counties to a double-circuit system of 230 kV or 500 kV. The new deadline for public comments is Sept. 28, 2023.

Previously, the end of the comment period was Sept. 14, 2023, per the Federal Register Notice. The extension is for two weeks and ends Sept. 28.

“Public input is critical as we continue to evaluate the proposed project,” said Pahrump Field Office Manager Nicholas Pay. “The most useful comments concern the scope of the environmental impact statement analysis, potential alternatives, and identification of relevant information and studies.”

The project would include amending portions of existing right-of-way grants to construct, operate, maintain, and eventually decommission approximately 155 miles of transmission system upgrades across approximately 4,900 acres of federal public lands. More information about the proposed project can be found on the BLM National NEPA Register.
