On Tuesday, Tucson Electric Power Company was granted a time extension for its Certificate of Environmental Compatibility giving the company additional time to complete construction of a 138kV transmission line to serve the Rosemont mine in Southern Arizona.
The original Certificate of Environmental Compatibility was granted by the Arizona Corporation Commission in 2012 in Decision No. 73232 and gave Tucson Electric Power Company until June 12, 2019 to complete the transmission line. The extension will give the company until June 12, 2022 to complete the project.
The Rosemont Copper Company has secured all but one permit required by the CEC in order for construction on the transmission line to begin. The extension is to ensure that the project can be completed within the timeframe allowed by the Commission, as projects must be done prior to the deadline.
