Connecticut Siting Council

July 9, 1998

Decision and Order

Pursuant to the foregoing Findings of Fact and Opinion, the Connecticut Siting Council (Council) finds that the effects associated with the construction, operation, and maintenance of a new substation and its connection to an existing 115-kV transmission line located approximately 1,200 feet northwest of the intersection of Hopmeadow Street (Route 10) and Wolcott Road in the Town of Simsbury, Connecticut, including effects on the natural environment; ecological integrity and balance; forests and parks; scenic, historic, and recreational values; air and water purity; fish and wildlife; and public health and safety are not disproportionate either alone or cumulatively with other effects compared to need, are not in conflict with the policies of the State concerning such effects, and are not sufficient reason to deny the application. Therefore, the Council directs that a Certificate of Environmental Compatibility and Public Need, as provided by General Statutes § 16-50k, be issued to the Connecticut Light and Power Company (CL&P) for the construction, operation, and maintenance of a new substation and its connection to an existing 115-kV transmission line located approximately 1,200 feet northwest of the intersection of Hopmeadow Street (Route 10) and Wolcott Road in the Town of Simsbury, Connecticut.

Upon the establishment of any new standards, the facilities granted in this Decision and Order shall be brought into compliance with such standards as soon as practical.

a) A final site plan showing the placement of all substation equipment, structures, and buildings within the substation perimeter and the 23-kV feeder conduit;

b) An erosion and sediment control plan to protect the slope and wetlands adjacent to the site, consistent with the Connecticut Guidelines for Soil Erosion and Sediment Control as amended;

c) Provisions for storm water management and oil containment;

d) Provisions for noise monitoring, at least twice during normal operations, once during the day and once at night.

b) Installation of the storm water management and oil containment devices;

c) Removal of the temporary substation.

4. The Certificate Holder shall notify the Council if and when substation operations terminate.

5. The Certificate Holder shall provide the following to the Council:

a) A six month report on the electric and magnetic field measurements at the locations of the pre-construction survey, and at the southern conductor of the transmission tap line.

b) A first year operating report, to be submitted to the Council within three months after the conclusion of the first year of operation, to include:

1. As-built drawings of all buildings, structures, and conduit;

2. The final total cost of the project;

3. Information relevant to the overall condition, safety, reliability, and operation of the substation.

6. Unless otherwise approved by the Council, this Decision and Order shall be void if all construction authorized herein is not completed within five years of the effective date of the Decision and Order, or within five years after all appeals to this Decision and Order have been resolved.

By this Decision and Order, the Council disposes of the legal rights, duties, and privileges of each party named or admitted to the proceeding in accordance with Section 16-50j-17 of the Regulations of Connecticut State Agencies.
