| Project Name: |
Cathodic Protection Installation at Eastshore-Dumbarton 115kV, Tower 003/023 |
| City/County: |
Union City, Alameda County |
| Comment Period: |
10/15/2024 - 11/4/2024 |
| Project Description: |
The purpose of the proposed activity is to prevent corrosion of metal tower foundations. PG&E will be installing a corrosion protection system, which includes a zinc rod(s) and a wire(s) being placed underground near the towers. Through a process called cathodic protection (CP), this allows the zinc rods to corrode instead of the tower footing. CP systems can last 30 years or more. |
