2012, March 6: staff recommendation; to alter an existing crossing of the Merrimack River in Merrimack and Litchfield, New Hampshire by altering the material, height, location of both support structures as well as increasing the conductor size and
material, increasing the size and material of the static wire which serves as a shield wire and replacing the communication wire from an ADSS type to an OPGW line (84 fiber optic cable). The relocation of the existing support structures of an existing 115 kv transmission line (Circuit K- 165 referred to as
the “Busch Tap”) on both sides of the Merrimack River allows for proper clearance from a newly proposed circuit H- 123 (115 kV) that will be installed between Line 380 (345kV) and the relocated K-165 (115 kV)
