The South of Birds Landing 230 kV Transmission Line Reconductoring Project was needed to accommodate wind energy facilities in the Montezuma Hills in Solano County and involved the reconductoring of 11 miles of 230 kV transmission line. The majority of the project spanned an area predominately used as dry-land wheat farming and livestock grazing (sheep). The northern portion of the project is located in the northwestern portion of the Collinsville – Montezuma Hills Wind Resource Area. The southern portion of the project is adjacent to the Antioch Dunes National Wildlife Refuge and spans residential, industrial, and agricultural portions of Antioch.
ETIC storm water professionals prepared, maintained, and amended the project SWPPP and performed the SWPPP compliance inspections and monitoring throughout the duration of the construction activities.

The project was performed in compliance with the requirements set forth in the following permits:
The species and habitats of concern on the project included the:
The SWPPP routine site inspections included before, during, and after precipitation events to monitor BMPs and document any storm water concerns. Recommendations for BMP repair and/or maintenance were recorded and ETIC construction personnel performed the necessary BMP maintenance and/or repairs.
