The Clay-DeWitt and Clay-Teall Rebuild Project is a 115,000 volt (or, 115kV) electric transmission line project that will enhance the reliability of the electric system in the Syracuse area. The project will be constructed in the communities of Clay, Cicero, DeWitt and Salina, in Onondaga County, New York

Article VII

The Project team worked with various state and federal agencies to receive approval and certification for the Project, which began with an application to the New York State Public Service Commission (PSC, or Commission) for a Certificate of Environmental Compatibility and Public Need ("Certificate") under Article VII of the State Public Service Law. The Article VII process involves an evaluation of all potential impacts from the Project and includes a detailed environmental impact assessment. Other agencies, like the Department of Agriculture and Markets and the Department of Environmental Conservation, are parties to the Article VII process. The Commission issued an order granting the Project its Certificate on April 23, 2018, allowing for the Project to be constructed. 

Environmental Management & Construction Plan

National Grid received approval by the PSC of the Project's Environmental Management and Construction Plan (EM&CP) on June 13, 2019. The EM&CP includes best practices for construction as well as the Project's final design.

With the EM&CP approved, DPS will issue a Notice to Proceed with Construction. The community, including affected landowners, will receive a Construction Commencement Notice before the start of construction.

Other Permits

Permits from other agencies are also required before construction can start. The U.S. Army Corps of Engineers will issue a permit under the Clean Water Act for construction activities in any waters under its jurisdiction (these typically include wetlands in upstate New York). The Federal Aviation Administration (FAA) also reviews the project and makes determinations regarding structure heights and proximity to air fields. New York State Department of Transportation (DOT) permits will also be required for various Project road crossings.

The permitting process includes opportunities for public involvement and comment from permitting through construction. To contact National Grid with a question or comment, click the "Contact Us” link above.

The Project is comprised of seven segments, each with a unique transmission corridor and construction plan. Below are descriptions of each segment. For segment locations, please see the Project Map above.

Segment 1 begins at the Clay Substation near the intersection of Caughdenoy Road and Verplank Road, travels northeast for 2.72 miles, ending near the intersection of Clarecastle Path and Longford Path. Currently, the corridor contains three single-circuit 115kV H-frame structures standing approximately 57—65 feet tall. The two outside structures and their conductors (wires) would be removed, leaving one existing single-circuit 115kV H-frame structure that stands approximately 65 feet tall. The structures that are removed would not be replaced.

Segment 2 Located in the Town of Cicero, Segment 2 begins near the intersection of Clarecastle Path and Longford Path, travels east then southeast for 1.31 miles, ending at the Bartell Road Substation, south of St. Elmos Drive. Currently, the corridor contains one double-circuit 115kV lattice structure, standing approximately 57 feet tall, along with a shorter 34.5kV sub-transmission pole for a portion of the segment. The 115kV lattice structures and conductor would be removed and not replaced.

Segment 3 Located in the Town of Cicero, Segment 3 begins at the Bartell Road Substation south of St. Elmos Drive, travels southeast for 2.19 miles and ends near the intersection of State Route 11 and Meltzer Court. Currently, the corridor contains one double-circuit 115kV lattice structure, standing approximately 65 feet tall, along with a 34.5kV sub-transmission pole that stands approximately 39 feet tall. The 115kV lattice structure would be removed and replaced with a double-circuit 115kV monopole structure made of weathering steel, standing approximately 80 feet tall. The centerline of the new monopole structure would be placed approximately 50 feet from the edge of the existing transmission right-of-way.

Segment 4 Located in the Town of Cicero, Segment 4 begins near the intersection of State Route 11 and Meltzer Court, travels southeast for 2.55 miles and ends near where the transmission corridor crosses Darby Road. Currently, the corridor contains a double-circuit 115kV lattice structure, standing approximately 65 feet tall, along with a 34.5kV sub-transmission pole that stands approximately 39 feet tall. The 115kV lattice structure would be removed and replaced with a double-circuit 115kV monopole structure made of weathering steel, ranging from approximately 80 feet to 110 feet tall. In some areas, the structure centerline will remain the same as existing for the corridor; in other areas, the structure centerline will shift. For specific structure height and centerline questions, please contact the Project team via the "Contact Us” link above.

Segment 5 Located in the Towns of Cicero and DeWitt, Segment 5 begins near where the transmission corridor crosses Darby Road, travels southeast for 4.18 miles and ends near the junction of Northern Boulevard and East Molloy Road. Currently, the corridor contains two single-circuit 115kV H-frame structures that stand approximately 57—65 feet tall. Some areas of the corridor also contain a double-circuit 115kV lattice structure that stands approximately 65 feet tall, and a 34.5kV sub-transmission pole that stands approximately 34 feet tall. For the first 2.27 miles of the corridor, both existing 115kV H-frame structures would be removed and replaced with two single-circuit 115kV monopole structures standing approximately 80 feet tall and made of weathering steel. For the next 1.91 miles, the westernmost existing 115kV H-frame would be removed and replaced with a single-circuit 115kV monopole structure, also standing approximately 80 feet tall and made of weathering steel. The 115kV structures' centerline will be shifted to the east.

Segment 6 Located in the Towns of DeWitt and Salina, Segment 6 begins near the junction of Northern Boulevard and East Molloy Road, travels southwest for 2.58 miles and ends at the Teall Avenue Substation near the intersection of Townline Road and Factory Avenue. Currently, the corridor contains four separate single-circuit 115kV H-frame structures, standing approximately 57 feet tall, and one 34.5kV sub-transmission pole standing approximately 34 feet tall. The northernmost H-frame structure would be removed and replaced with one single-circuit 115kV monopole structure made of weathering steel, standing approximately 80 feet tall. The structure centerline would be the same as what exists today.

Segment 7 Located in the Towns of Clay and Cicero, Segment 7 begins at the Clay Substation near the intersection of Caughdenoy Road and Verplank Road, travels southeast for 2.5 miles and ends near the intersection of State Route 11 and Meltzer Court. The corridor currently contains two single-circuit 345kV lattice structures standing approximately 87 feet tall, and one double-circuit 345/115kV lattice structure standing approximately 134 feet tall. A new double-circuit 115kV monopole structure made of weathering steel and standing approximately 95 feet tall would be constructed on the southern end of the corridor. No structures would be removed from the corridor.

Rebuilding an electric transmission line involves a variety of activities set out in phases:

1. Site Preparation:
The first phase of site preparation and construction is tree and brush clearing. Clearing allows construction crews to build access roads and remove any trees that are in danger of falling into the transmission lines. Marshaling yards will be established to house materials and construction crews.

2. Environmental Controls:
Next, environmental controls will be installed to mitigate construction impacts to the area. These can include matting, silt fence, concrete washouts, among others.

3. Transmission Line Rebuilding:
The next phase is transmission line rebuilding, where foundations are poured, structures are spotted and erected, and new wire is strung and energized. Old structures are removed from the transmission right-of-way. This work is done with a variety of equipment, including cranes and other heavy equipment, using temporary work pads.

4. Restoration:
The final phase of construction is ground surface restoration, in which the construction area is restored to the condition it was in before construction.

During the vegetation clearing phase of the Project, National Grid will employ a variety of Integrated Vegetation Management (IVM) techniques. Mechanical clearing, hand cutting, mowing and selective herbicide applications are a few examples of such techniques. This work will be conducted by New York State Department of Conservation-licensed contractors in site-specific locations prescribed by National Grid Forestry staff. The herbicide application—as part of a planned IVM program—will enable National Grid to create stable, low-growing plant communities that require minimal maintenance. The labels for each of the herbicides to be used can be found below.
