Assessments underway as part of Oncor Transmission Line proposal as hundreds give feedback

Assessments underway as part of Oncor Transmission Line proposal as hundreds give feedback

Multiple assessments currently are underway along a 200-plus–mile route transecting 14 Texas counties including Llano, Mason and San Saba. It is all part of the licensing process of a major transmission line being proposed by Oncor and LCRA TSC (Lower Colorado River Authority Transmission Services Corporation). 

“We are still in the ‘Environmental Assessment and Routing Study’ and ‘Certificate of Convenience and Necessity (CCN) Application’ stages,” according to Andrew Clark with Oncor’s media relations department, who answered questions for the News in an email on Oct. 21. “The next step will be for Oncor and LCRA to file the joint application with the PUCT (Public Utility Commission of Texas). Upon filing, official notice will be sent to all directly affected landowners and will be published in several newspapers across the project area. Oncor and LCRA are diligently working to refine routing options and complete the necessary steps to finalize the joint application.”

The “Environmental Assessment and Routing Study” stage typically takes 6-12 months and includes reviewing environmental, archaeological and historical data within the study area and mapping possible routes and alternative routes, according to the flowchart provided by LCRA TSC.
